I call my beloved pair of grey jeans “Saturday Pants”.Originally hand-me-downs from a former roommate， they’re just a touch too informal to wear to the office， but for many years were my favourites to wear on the weekends for going shopping or hanging out with friends.But I needed to rethink my day-off clothes when the jeans got a large rip （撕开的大口子） next to the right back pocket.
I will happily mend （缝补） anything that rips a little， but usually when clothing in our household gets bigger holes I send these items away for recycling or add them to my collection of scrap fabric （废旧布料）.However， I couldn’t quite bring myself to add the Saturday Pants to either pile.Instead， they sat on the shelf under my other jeans for longer than I’d care to admit.
Then I came across Softpaw Vintage， the beautifully patched （打补丁的） and reworked clothes of Taylor Randal， a creator in Rhododendron， Oregon.Her perfectly patched up jeans gave me the inspiration to reuse the Saturday Pants with creative mending.
I went ahead and added a patch to the inside of my jeans to hopefully stop further tearing and to provide a strong base for the rest of the project.I then added more decorative patches to the outward-facing part of the jeans.My old favourites finally came back as my day-off clothes.I find it comforting that if these repairs don’t hold or work， I can add more patches or try a different technique.
To me， creative mending takes visible mending a step further， offering a space to play and be artistic with an eye to a functional end.As we attempt to move beyond throwaway culture and fight for the right to repair， it’s also worth finding pleasure and joy on the way to reducing our impact on the environment.
24.What is special about the author’s Saturday Pants？（ ）
A.They are a gift sent by her family. B.They are a pair of second-hand jeans.
C.They are designed by Taylor Randal. D.They are her favourites to wear to work.
25.What did the author decide to do after getting to know Softpaw Vintage？（ ）
A.Repair the hole in her beloved jeans creatively.
B.Pass down her favourite items to others.
C.Donate her old clothes to be recycled.
D.Put her clothes on the shelf in order.
26.What do we know about the author？（ ）
A.She has a strong sense of tradition. B.She dreams of opening a clothing store.
C.She enjoys bringing everything to perfection. D.She is a person with environmental awareness.
27.What is the best title for the text？（ ）
A.My Unique Way to Become a Fashion Designer
B.My Efforts to Make Full Use of Day-off Clothes
C.My Fight for the Right to Get a Pair of Designer Jeans
D.My New Strategy to Make Favourite Clothes Last Forever
C
Not only does the use of plastic water bottles hurt your wallet， but it also causes pollution， wastes energy， and surprisingly wastes water.Only 23% of the plastic in America ends up in recycling bins， meaning over $1 billion worth of plastic is treated as rubbish a year.Recently， Skipping Rocks Lab has invented a kind of water bottle called Ooho.
It’s a kind of convenient， clear water bottle that can either be drunk or eaten.To drink it， you can either get rid of the membrane （膜） or tear a hole in the membrane with your teeth to pour the water into your mouth.To eat it， you simply put the whole bottle in your mouth.It’s completely insipid so you needn’t worry about any taste.
It aims for large outdoor events where tons of plastic bottles are used and frequently left behind as litter.Too much plastic is sure to do harm to the environment， which could account for the purpose of such a new invention.
The team has been working for the past two years to develop the technology and materials that are needed to produce Ooho.The price for an only bubble （泡状物） or a unit of bubbles hasn’t been decided yet， but it costs about two cents to create a unit， which is cheaper than plastic bottles.The team has also been selling Ooho water bottles in London for the past six months.
Ooho is catching many people’s attention and has raised over $1 million in only three days.It’s mostly being sold at events at the moment to interest the buyers while the production machine is getting up and running.It’s quickly making a rise， so keep an eye out for these bottles of the future.
28.How is most plastic in America dealt with？（ ）
A.It is wasted by people. B.It is reused as new energy.
C.It is buried under the ground. D.It is applied to new technology.
29.What does the underlined word “insipid” in Paragraph 2 probably mean？（ ）
A.Sweet. B.Delicious.
C.Tasteless. D.Interesting.
30.What can we infer about Ooho？（ ）
A.It plans to be sold at a very low price.
B.It has some advantages over plastic bottles.
C.It has taken the place of plastic bottles in London.
D.Proper materials of making Ooho are hard to find.
31.Who might be the target readers？（ ）
A.Scientists. B.Experts.
C.Environmentalists. D.The public.
D
Scientists working on an experimental anti-ageing therapy have announced that they have broken a record by extending the lifespan of a lab rat called Sima.Named after the Hindi word for “limit” or “boundary”， Sima is the last remaining survivor that received infusions （输注） of blood plasma （血浆） taken from young animals to see if the treatment prolonged their lives.
Sima， who was born on 28 February 2019， has lived for 47 months， longer than the 45.5 months believed to be the oldest age recorded in scientific literature for a female Sprague Dawley rat， the researchers say.“We have the oldest living female Sprague Dawley rat，” said Dr Harold Katcher， a former biology professor at the University of Maryland， now chief scientific officer at Yuvan Research， a California-based start-up.
Researchers have rushed to produce and test therapies based on young blood plasma after numerous experiments found that infusions could give new energy and strength to ageing organs and tissues.But while studies have found benefits for rats， there is no evidence to date that the approach to youthfulness will help humans avoid the passage of time， despite the best wishes of Silicon Valley.
The results from Katcher’s latest study will be written up when Sima dies， but data gathered so far suggests that eight rats that received infusions that have no therapeutic effect lived for 34 to 38 months， while eight that received a purified and concentrated form of blood plasma， called E5， lived for 38 to 47 months.Rats normally live for two to three years， though the oldest ever one is a brown rat that survived on a restricted calorie diet for 4.6 years.
“The real point of our experiments is not so much to extend lifespan， but to extend youthspan， to make people look and feel younger， to make their golden years really potentially golden years， instead of years of pain，” Katcher said.“But the fact is， if you manage to do that， you also manage to lengthen life and that’s not a bad side-effect.”
Dr Steve Horvath is now a principal investigator at Altos Labs in San Diego， which is not working with Yuvan.“I think the results are impressive，” he said.“Some people won’t accept the results due to the low sample size.One swallow does not make a summer.But I believe the results because several studies support them.” He expects there will be safe and effective treatments from plasma research in the next 20 years.
32.How is Sima different from other rats？（ ）
A.It is the oldest Sprague Dawley lab rat. B.It has the rarest blood type.
C.It is the first Sprague Dawley rat. D.It has survived several experiments.
33.What have researchers focused on when it comes to anti-ageing therapies？（ ）
A.Purifying and concentrating blood plasma. B.Developing effective long-term diet plans.
C.Testing infusions of young blood plasma. D.Replacing ageing organs and tissues.
34.What can we infer from the words of Katcher in Paragraph 5？（ ）
A.Humans will finally live much longer than before.
B.The experiments have caused potential problems.
C.His team is worried about side-effects.
D.Youthspan is what his team cares about.
35.What does Horvath think of Katcher’s study？（ ）
A.It is worth believing. B.It requires further testing.
C.It studies too small samples. D.It is effective in treating disease.

Breakthroughs from science and technology have completely changed much of human life.36.（ ） Here are some examples of traditional methods， old ideas， and ancient techniques that are helping to solve problems here in the 21st century.
Growing food in the desert.
Yacouba Sawadogo， a farmer from Burkina Faso， a landlocked country in West Africa， has led the transformation of barren， dry land into productive agriculture.37.（ ） Pits （坑） are dug into the ground， allowing water to gather in one place.Since popularizing the use of pits， Sawadogo has helped increase food production in Burkina Faso.
38.（ ）
Digging holes forms an important part of agriculture in Zimbabwe， too.Here the use of deep holes is helping to grow crops without the need for intensive ploughing.The holes are covered with soil， straw （稻草） and other materials to keep in as much moisture as possible.Unlike more conventional ploughing-based planting， this technique means water can be directed precisely where it is needed.
Saving a forest by burning it.
39.（ ） The reason is that they can clear out dead organic materials， open the forest floor up to sunlight， and nourish the soil.But this practice is nothing new.Researchers have found that ancient Amazon indigenous civilizations had long been using fires to clear the rainforest in a carefully controlled way， to limit the risk of large outbreaks.
Realizing natural pest control.
All farmers understand the importance of pest control.In Thailand， some farmers have avoided modern， chemical-based methods and are instead using ducks known locally as “ped lai thoong”， which means “field chasing （奔跑的） ducks”.40.（ ） They also eat rice husks （外皮） after harvests.
A.Building with naturally occurring materials.
B.Creating deep holes for more precise farming.
C.Many forests are benefitting from periodic fires.
D.He has done it thanks to an ancient way of trapping water in the soil.
E.This ground-based technique allows growers to gather accurate data in real time.
F.These birds are left to wander freely among fields， eating plenty of unwanted pests.
G.But sometimes， tried-and-tested ideas that have stood the test of time can still be of use.

I had just finished my dance class， and it was a disaster： I started on the wrong foot and couldn’t get the steps that other students seemed to do easily.I began to 41 my talent for ballet.
Just then， my big sister Julissa arrived.She took one 42 at me and asked， “What’s wrong， Lakeisha？”
“Nothing，” I said 43 .
“Uh huh，” Julissa replied.“Looks like a（n） 44 ‘nothing’ to me， so tell me what happened.”
“Well，” I mumbled （咕哝）， “maybe I shouldn’t be taking 45 classes？It felt like I was the only one who couldn’t land her pirouettes （单脚尖旋转） today.”
“Listen，” she said， “not every day is a（n） 46 one， and not everything you try is going to 47 the way you want.The point is to keep 48 .Remember that and you’ll be fine.”
“I tried my best， but ...” I replied.
Looking at me seriously， Julissa said， “Maybe ballet is not your 49 yet， but dance is. I see how you shake and move all the time.There are all kinds of 50 to dance， so maybe you just need to 51 your own style.Why not stick to jazz dance？You are so good at it.”
I thought about her 52 and my performances carefully.Yes， why had I never 53 that？I wanted to be a ballet dancer， but it may not be a good 54 for me.It seemed as if I suddenly saw the light.
“You’re right，” I replied. “Thank you.I’m so 55 to have you to guide me！”

Danish researchers have just set a new record for data transmission （传输）.56. （use） one small computer chip， they moved about 1.8 petabits of data per second.That equals 122 million 57. （movie） streaming at the same time.In their new demonstration， 8，251 beams of light 58. （carry） more than an entire world’s worth of data.For this test， the date traveled 7.9 kilometers along a fiber optic cable （光纤电缆）.
That’s truly impressive， notes Bill Corcoran. 59. （previous）， an accomplishment like this would have taken many chips and consumed far more energy.Corcoran， a physicist 60. wasn’t involved in this research， knows a lot about this field.His group had held the record for the 61. （high） data transmission rate with a single chip since 2020.Corcoran says，“62. is great to see records being broken at this pace.”
“Even though no one needs to move data so quickly right now， researchers are planning ahead.Such 63. high rate may be useful in data centers even sooner，” one of the Danish researchers says.More work should 64. （do） before the new device can be put into real-world use.Right now， the energy needed for difficult computing tasks already poses a risk to climate.The new 65. （innovate） in moving data could help lessen the Internet’s climate impact.

Tick-tock.Tick-tock.
Andreas watched the clock.It seemed to be moving very slowly.This was his last class of the day — biology.After school there would be tryouts for the basketball team.Andreas had been practicing for months.He loved the feeling of the basketball in his hands and the sound the ball made when it sailed through the net.
“Andreas！”
Andreas’s best friend， Tyrell， was trying to get his attention.
“I feel like this class will never end，” said Tyrell.
“Me， too，” said Andreas.
Tyrell and Andreas had been best friends since kindergarten （幼儿园）.Tyrell loved basketball， too， and he was also trying out for the basketball team.Andreas was glad he’d have his best friend by his side.
Suddenly the bell rang and class was over.Andreas and Tyrell ran to the gym and there were at least 60 boys crowded onto the bleachers （露天看台）.
“Oh no，” said Tyrell.“I never imagined there would be so many kids trying out for the basketball team.”
Andreas knew the basketball team only had room for 20 people.That meant two-thirds of the kids there wouldn’t make the team.Andreas and Tyrell looked at each other， worried.
The coach blew a whistle （哨子） and the tryouts began.Andreas and Tyrell were separated into different groups.First Andreas ran sprints （短跑） across the gym， over and over until his legs felt weak， and he was out of breath.Then， the coaches divided them into teams to play against one another.As soon as he felt his hands on the basketball， Andreas felt better.All the nights of practicing paid off as he took shots from the 3-point line.Not all of the shots went in， but a lot of them did.
Tyrell was waiting outside when the tryouts were over.
“How did it go？” Andreas asked.
“I don’t know ...I think it went all right，” said Tyrell.
Andreas felt worried.He knew he had played well， but was it good enough？
“It’s okay，” said Tyrell.Tyrell had known Andreas for so long that he could see when Andreas was upset.“I’m sure you made it.”
They walked the rest of the way home in silence.
注意：1.续写词数应为150左右；
2.请按如下格式作答。
The next morning Andreas couldn’t eat any of his breakfast.
“But I didn’t see my name，” Andreas replied.

M：Here is the news from Dallas.
Walmart posted its worst monthly sales results in history， declaring a large decrease in April.
Monthly sales measure sales gains or losses at stores open for at least a year.They are an obvious sign of the returns a supermarket earns， and thus an influence on the amount of profit it makes.Most US supermarkets are reporting their April results on Thursday.
Walmart’s 5% drop in the four-week period fell below its earlier forecast of “flat” sales of a 2% to 3% decrease.In a recorded phone message Thursday， Walmart blamed bad weather last month in most US areas.
Walmart’s chief financial officer warned a month ago that the company’s earlier goal of earnings for its latest quarter would be “a challenge” to achieve， considering what the company foresaw as a difficult April.The company didn’t provide an update.It did， however， predict a sales gain for this month of a small decrease.Walmart will report its results for its first quarter on Tuesday.

语篇解读：本文是一篇说明文。文章主要介绍了一种可以食用的水瓶Ooho的使用方法、制作成本以及市场前景。

34.D 推理判断题。根据第五段中Katcher所说可知，他的团队真正关注的是如何延长人类的青春岁月。
35.A 推理判断题。根据最后一段中Steve Horvath教授所说的话可知，虽然有些人对该抗衰老实验持怀疑态度，但他认为该实验有理论支持，其实验结果还是可信的。

49.B 根据本段中Maybe ballet is not your 49 yet， but dance is.和Why not stick to jazz dance？ You are so good at it.可知，作者的姐姐建议作者坚持跳爵士舞，因为作者擅长这种舞蹈。由此推断，她劝作者说：“也许芭蕾舞不是你的菜，但舞蹈是……跳舞有各种各样的方式，也许你只是需要找到自己的风格……”。thing在此意为“适当的东西，合适的东西”。
50.C 参见上题解析。
51.A 参见第49题解析。
52.D 本段是作者对姐姐的话的思考，故选words。
53.B 根据本段中I wanted to be a ballet dancer， but it may not be a good 54 for me.可知，作者思考自己为什么从来没想过这一点（坚持跳爵士舞，因为自己擅长这种舞蹈）。她想成为芭蕾舞演员，但这对她来说也许不是一个好选择。
54.C 参见上题解析。
55.A 根据本段中作者所说的话可知，作者肯定了姐姐的建议，对姐姐表示感谢。由此推断，作者说她很幸运有姐姐来引导她。

M：Here is the news from Dallas.
Walmart posted its worst monthly sales results in history， declaring a
large decrease in April.
Monthly sales measure sales gains or losses at stores open for at least a
year.They are an obvious sign of the returns a supermarket earns， and
thus an influence on the amount of profit it makes.Most US supermarkets
are reporting their April results on Thursday.
Walmart’s 5% drop in the four-week period fell below its earlier forecast
of “flat” sales of a 2% to 3% decrease.In a recorded phone message
Thursday， Walmart blamed bad weather last month in most US areas.
Walmart’s chief financial officer warned a month ago that the
company’s earlier goal of earnings for its latest quarter would be “a
challenge” to achieve， considering what the company foresaw as a
difficult April.The company didn’t provide an update.It did，
however， predict a sales gain for this month of a small decrease.Walmart
will report its results for its first quarter on Tuesday.

I call my beloved pair of grey jeans “Saturday Pants”.Originally
hand-me-downs from a former roommate， they’re just a touch too
informal to wear to the office， but for many years were my favourites to
wear on the weekends for going shopping or hanging out with friends.But
I needed to rethink my day-off clothes when the jeans got a large rip （撕
开的大口子） next to the right back pocket.
I will happily mend （缝补） anything that rips a little， but usually
when clothing in our household gets bigger holes I send these items away
for recycling or add them to my collection of scrap fabric （废旧布
料）.However， I couldn’t quite bring myself to add the Saturday Pants
to either pile.Instead， they sat on the shelf under my other jeans for
longer than I’d care to admit.
Then I came across Softpaw Vintage， the beautifully patched （打
补丁的） and reworked clothes of Taylor Randal， a creator in
Rhododendron， Oregon.Her perfectly patched up jeans gave me the
inspiration to reuse the Saturday Pants with creative mending.
I went ahead and added a patch to the inside of my jeans to hopefully
stop further tearing and to provide a strong base for the rest of the project.I
then added more decorative patches to the outward-facing part of the
jeans.My old favourites finally came back as my day-off clothes.I find it
comforting that if these repairs don’t hold or work， I can add more
patches or try a different technique.
To me， creative mending takes visible mending a step further，
offering a space to play and be artistic with an eye to a functional end.As
we attempt to move beyond throwaway culture and fight for the right to
repair， it’s also worth finding pleasure and joy on the way to reducing
our impact on the environment.

A. They are a gift sent by her family.
B. They are a pair of second-hand jeans.
C. They are designed by Taylor Randal.
D. They are her favourites to wear to work.

友穿过的旧裤子，虽然不太正式没法上班穿，但却是作者周末
最喜欢穿的裤子。hand-me-downs别人穿过的衣服；a touch 轻
微，稍许。
25. What did the author decide to do after getting to know Softpaw
Vintage？（ ）
A. Repair the hole in her beloved jeans creatively.
B. Pass down her favourite items to others.
C. Donate her old clothes to be recycled.
D. Put her clothes on the shelf in order.
解析： 细节理解题。根据第一段中的the jeans got a large rip
（撕开的大口子） next to the right back pocket和第三段内容可
知，Softpaw Vintage 是由Taylor Randal设计的服装，这些漂亮的
打补丁的牛仔裤给了作者灵感，让作者决定创意缝补那条破了的
牛仔裤。
26. What do we know about the author？（ ）

B. She dreams of opening a clothing store.
C. She enjoys bringing everything to perfection.

A. My Unique Way to Become a Fashion Designer
B. My Efforts to Make Full Use of Day-off Clothes
C. My Fight for the Right to Get a Pair of Designer Jeans
D. My New Strategy to Make Favourite Clothes Last Forever
解析： 标题归纳题。通读全文可知，作者最喜欢的裤子破
了，但她既不愿意把这条裤子送去回收，也不愿意把它当作废旧
布料，最终她通过创意缝补技巧让这条破了的裤子焕然新生。因
此，D项作标题最符合本文主旨，其中的My New Strategy指代
creative mending。

Not only does the use of plastic water bottles hurt your wallet， but it
also causes pollution， wastes energy， and surprisingly wastes
water.Only 23% of the plastic in America ends up in recycling bins，
meaning over $1 billion worth of plastic is treated as rubbish a
year.Recently， Skipping Rocks Lab has invented a kind of water bottle
called Ooho.
It’s a kind of convenient， clear water bottle that can either be
drunk or eaten.To drink it， you can either get rid of the membrane
（膜） or tear a hole in the membrane with your teeth to pour the water
into your mouth.To eat it， you simply put the whole bottle in your
mouth.It’s completely insipid so you needn’t worry about any taste.
It aims for large outdoor events where tons of plastic bottles are used
and frequently left behind as litter.Too much plastic is sure to do harm to
the environment， which could account for the purpose of such a new
invention.
The team has been working for the past two years to develop the
technology and materials that are needed to produce Ooho.The price for an
only bubble （泡状物） or a unit of bubbles hasn’t been decided yet，
but it costs about two cents to create a unit， which is cheaper than plastic
bottles.The team has also been selling Ooho water bottles in London for
the past six months.
Ooho is catching many people’s attention and has raised over $1
million in only three days.It’s mostly being sold at events at the moment
to interest the buyers while the production machine is getting up and
running.It’s quickly making a rise， so keep an eye out for these bottles
of the future.

B. It is reused as new energy.
C. It is buried under the ground.
D. It is applied to new technology.
解析： 细节理解题。根据第一段第二句Only 23% of the plastic
in America ends up in recycling bins， meaning over $1 billion worth
of plastic is treated as rubbish a year.可知，在美国大多数塑料被人
们浪费掉了。
29. What does the underlined word “insipid” in Paragraph 2 probably
mean？（ ）
A. Sweet. B. Delicious.
C. Tasteless. D. Interesting.
解析： 词义猜测题。根据画线词上文的To eat it， you simply
put the whole bottle in your mouth.和其后的so you needn’t worry
about any taste可知，这种水瓶可以吃，你不必担心有任何味道，
这是因为它是完全无味的。由此推测，insipid意为“无味道
的”，与tasteless意思相近。
30. What can we infer about Ooho？（ ）
A. It plans to be sold at a very low price.
B. It has some advantages over plastic bottles.
C. It has taken the place of plastic bottles in London.
D. Proper materials of making Ooho are hard to find.

C. Environmentalists. D. The public.
解析： 推理判断题。通读全文尤其根据最后一段可知，Ooho
主要出售给大型户外活动，这种瓶子正在崛起中，需要公众的关
注。由此可推知，文章是写给大众看的。
D
Scientists working on an experimental anti-ageing therapy have
announced that they have broken a record by extending the lifespan of a
lab rat called Sima.Named after the Hindi word for “limit” or
“boundary”， Sima is the last remaining survivor that received
infusions （输注） of blood plasma （血浆） taken from young animals
to see if the treatment prolonged their lives.
Sima， who was born on 28 February 2019， has lived for 47
months， longer than the 45.5 months believed to be the oldest age
recorded in scientific literature for a female Sprague Dawley rat， the
researchers say.“We have the oldest living female Sprague Dawley
rat，” said Dr Harold Katcher， a former biology professor at the
University of Maryland， now chief scientific officer at Yuvan Research，
a California-based start-up.
Researchers have rushed to produce and test therapies based on young
blood plasma after numerous experiments found that infusions could give
new energy and strength to ageing organs and tissues.But while studies
have found benefits for rats， there is no evidence to date that the
approach to youthfulness will help humans avoid the passage of time，
despite the best wishes of Silicon Valley.
The results from Katcher’s latest study will be written up when Sima
dies， but data gathered so far suggests that eight rats that received
infusions that have no therapeutic effect lived for 34 to 38 months， while
eight that received a purified and concentrated form of blood plasma，
called E5， lived for 38 to 47 months.Rats normally live for two to three
years， though the oldest ever one is a brown rat that survived on a
restricted calorie diet for 4.6 years.
“The real point of our experiments is not so much to extend
lifespan， but to extend youthspan， to make people look and feel
younger， to make their golden years really potentially golden years，
instead of years of pain，” Katcher said.“But the fact is， if you
manage to do that， you also manage to lengthen life and that’s not a bad side-effect.”
Dr Steve Horvath is now a principal investigator at Altos Labs in San
Diego， which is not working with Yuvan.“I think the results are
impressive，” he said.“Some people won’t accept the results due to
the low sample size.One swallow does not make a summer.But I believe
the results because several studies support them.” He expects there will
be safe and effective treatments from plasma research in the next 20 years.

命最长的老鼠。
33. What have researchers focused on when it comes to anti-ageing
therapies？（ ）
A. Purifying and concentrating blood plasma.
B. Developing effective long-term diet plans.
C. Testing infusions of young blood plasma.
D. Replacing ageing organs and tissues.
解析： 细节理解题。根据第一段第二句以及第四段中eight rats
that received infusions that have no therapeutic effect和while eight
that received a purified and concentrated form of blood plasma可知，
在研究抗衰老疗法的过程中，研究者关注的是年轻动物的血浆产
生的效果。
34. What can we infer from the words of Katcher in Paragraph 5？
（ ）
A. Humans will finally live much longer than before.
B. The experiments have caused potential problems.
C. His team is worried about side-effects.
D. Youthspan is what his team cares about.
解析： 推理判断题。根据第五段中Katcher所说可知，他的团
队真正关注的是如何延长人类的青春岁月。
35. What does Horvath think of Katcher’s study？（ ）
A. It is worth believing.
B. It requires further testing.
C. It studies too small samples.
D. It is effective in treating disease.
解析： 推理判断题。根据最后一段中Steve Horvath教授所说的
话可知，虽然有些人对该抗衰老实验持怀疑态度，但他认为该实
验有理论支持，其实验结果还是可信的。
第二节（共5小题；每小题2.5分，满分12.5分）
阅读下面短文，从短文后的选项中选出可以填入空白处的最佳选
项。选项中有两项为多余选项。
Breakthroughs from science and technology have completely changed
much of human life.36.（ ） Here are some examples of traditional
methods， old ideas， and ancient techniques that are helping to solve
problems here in the 21st century.
Yacouba Sawadogo， a farmer from Burkina Faso， a landlocked
country in West Africa， has led the transformation of barren， dry land
into productive agriculture.37.（ ） Pits （坑） are dug into the
ground， allowing water to gather in one place.Since popularizing the use
of pits， Sawadogo has helped increase food production in Burkina Faso.
Growing food in the desert.
38. （ ）
Digging holes forms an important part of agriculture in Zimbabwe，
too.Here the use of deep holes is helping to grow crops without the need
for intensive ploughing.The holes are covered with soil， straw （稻草）
and other materials to keep in as much moisture as possible.Unlike more
conventional ploughing-based planting， this technique means water can
be directed precisely where it is needed.
39. （ ） The reason is that they can clear out dead organic
materials， open the forest floor up to sunlight， and nourish the soil.But
this practice is nothing new.Researchers have found that ancient Amazon
indigenous civilizations had long been using fires to clear the rainforest in
a carefully controlled way， to limit the risk of large outbreaks.
Saving a forest by burning it.
All farmers understand the importance of pest control.In Thailand，
some farmers have avoided modern， chemical-based methods and are
instead using ducks known locally as “ped lai thoong”， which means
“field chasing （奔跑的） ducks”.40.（ ） They also eat rice
husks （外皮） after harvests.
A. Building with naturally occurring materials.
B. Creating deep holes for more precise farming.
C. Many forests are benefitting from periodic fires.
Realizing natural pest control.
E. This ground-based technique allows growers to gather accurate data in
real time.
F. These birds are left to wander freely among fields， eating plenty of
unwanted pests.
G. But sometimes， tried-and-tested ideas that have stood the test of time
can still be of use.

贫瘠干旱的土地变成了高产的农田，下文说明了这位农民推广使用挖
坑聚水的方法，帮助提高了该国的粮食产量。D项中的He指代上文中
提到的Yacouba Sawadogo， it指代上文中提到的情况，trapping water
in the soil与下文中描述的挖抗聚水法相呼应。
38. B 通读设空处下面一段可知，挖坑也是津巴布韦农业的重要组
成部分。通过挖出深坑，无需进行密集耕作便能种植庄稼。这种技术
可以将水精确地引导到需要的地方。B项概括了本段主旨，适合作小
标题。B项中的deep holes与段中的holes 和deep holes构成原词复现，
且precise farming与段中的water can be directed precisely where it is
needed相呼应。
39. C 下文说明了其中的原因是它们可以清除死去的有机物质，
让森林地面接触阳光，并滋养土壤。但研究人员发现，古代亚马
孙土著文明很早以前就在使用这种做法。C项与设空处后一句构成
因果关系。设空处后一句中的they指代C项中的periodic fires；C
项中的forests与小标题中的forest构成原词复现，且fires与下文中
的fires构成原词复现。
40. F 上文指出，一些泰国农民通过将鸭子放入稻田来消灭害虫，F
项对上文进行补充说明，其中的These birds指代设空处前一句中的鸭
群，eating与设空处后一句中的eat构成原词复现。

taking 45 classes？It felt like I was the only one who couldn’t land
her pirouettes （单脚尖旋转） today.”
“Listen，” she said， “not every day is a（n） 46 one，
and not everything you try is going to 47 the way you want.The point
is to keep 48 .Remember that and you’ll be fine.”
“I tried my best， but ...” I replied.

your 49 yet， but dance is. I see how you shake and move all the
time.There are all kinds of 50 to dance， so maybe you just need
to 51 your own style.Why not stick to jazz dance？You are so good at
it.”

why had I never 53 that？I wanted to be a ballet dancer， but it may
not be a good 54 for me.It seemed as if I suddenly saw the light.
“You’re right，” I replied. “Thank you.I’m so 55 to
have you to guide me！”

Danish researchers have just set a new record for data transmission （传输）.56. （use） one small computer chip， they moved about 1.8 petabits of data per second.That equals 122 million 57. （movie） streaming at the same time.In their new demonstration， 8，251 beams of light 58. （carry） more than an entire world’s worth of data.For this test， the date traveled 7.9 kilometers along a fiber optic cable （光纤电缆）.
That’s truly impressive， notes Bill Corcoran. 59. （previous）， an accomplishment like this would have taken many chips and consumed far more energy.Corcoran， a physicist 60. wasn’t involved in this research， knows a lot about this field.His group had held the record for the 61. （high） data transmission rate with a single chip
since 2020.Corcoran says，“62. is great to see records being broken at this pace.”
“Even though no one needs to move data so quickly right now，
researchers are planning ahead.Such 63. high rate may
be useful in data centers even sooner，” one of the Danish
researchers says.More work should 64. （do） before
the new device can be put into real-world use.Right now， the energy
needed for difficult computing tasks already poses a risk to
climate.The new 65. （innovate） in moving data
could help lessen the Internet’s climate impact.

第二节（满分25分）
阅读下面材料，根据其内容和所给段落开头语续写两段，使之构
成一篇完整的短文。
Tick-tock.Tick-tock.
Andreas watched the clock.It seemed to be moving very slowly.This
was his last class of the day — biology.After school there would be
tryouts for the basketball team.Andreas had been practicing for
months.He loved the feeling of the basketball in his hands and the sound
the ball made when it sailed through the net.
“Andreas！”
Andreas’s best friend， Tyrell， was trying to get his attention.
“I feel like this class will never end，” said Tyrell.
“Me， too，” said Andreas.
Tyrell and Andreas had been best friends since kindergarten （幼儿
园）.Tyrell loved basketball， too， and he was also trying out for the
basketball team.Andreas was glad he’d have his best friend by his side.
Suddenly the bell rang and class was over.Andreas and Tyrell ran to
the gym and there were at least 60 boys crowded onto the bleachers （露
天看台）.
“Oh no，” said Tyrell.“I never imagined there would be so many
kids trying out for the basketball team.”
Andreas knew the basketball team only had room for 20 people.That
meant two-thirds of the kids there wouldn’t make the team.Andreas and
Tyrell looked at each other， worried.
The coach blew a whistle （哨子） and the tryouts began.Andreas
and Tyrell were separated into different groups.First Andreas ran sprints
（短跑） across the gym， over and over until his legs felt weak， and he
was out of breath.Then， the coaches divided them into teams to play
against one another.As soon as he felt his hands on the basketball，
Andreas felt better.All the nights of practicing paid off as he took shots
from the 3-point line.Not all of the shots went in， but a lot of them did.
Tyrell was waiting outside when the tryouts were over.
“How did it go？” Andreas asked.
“I don’t know ...I think it went all right，” said Tyrell.
Andreas felt worried.He knew he had played well， but was it good
enough？
“It’s okay，” said Tyrell.Tyrell had known Andreas for so long
that he could see when Andreas was upset.“I’m sure you made it.”
They walked the rest of the way home in silence.
注意：1.续写词数应为150左右；
2. 请按如下格式作答。
The next morning Andreas couldn’t eat any of his breakfast.
“But I didn’t see my name，” Andreas replied.
参考范文：
The next morning Andreas couldn’t eat any of his breakfast.He
couldn’t wait anymore.He asked his mother to send him to school
early.Five minutes later， Andreas was standing in front of the gym.He
looked at the list.Tyrell’s name was at the very top — he had made it！
Andreas’s eyes moved down the list， slowly， reading every name.He
didn’t see his name anywhere.He felt very sad.Suddenly he heard
Tyrell’s happy voice， “Andreas！ We made it！”
“But I didn’t see my name，” Andreas replied.Tyrell came up to
Andreas， saying aloud， “Didn’t you look at the second sheet？”
Andreas realized he didn’t read it.He looked back at the list
hurriedly.Tyrell was right； there was a second sheet of paper
underneath.Andreas lifted up the first sheet of paper and saw his name at
the very top.He turned and gave Tyrell a high-five.They were going to be
on the basketball team together.
谢谢观看！
