UNIT 5 A delicate world
Ⅰ.阅读理解
（2025·乐山三模）If someone asked you to name a species in need of conservation， it wouldn’t take long for you to land upon the polar bear.As the most symbolic animal of the Arctic， polar bears perfectly adapt to such a tough environment.Although most are born on land， polar bears spend the majority of their lives around water and on the sea ice of the Arctic Ocean.While they are not facing upcoming extinction， the destruction caused to their habitats by climate change puts their long-term survival at risk and their numbers are predicted to decline by 30% by 2050.
It is estimated that there are 26，000 polar bears in the wild， living across countries that border the Arctic Ocean.They are excellent swimmers， able to reach a top speed of 6 mph.They have been known to travel areas of up to 600，000 sq km to find their prey （猎物）.Polar bears have an incredibly well-developed sense of smell and can discover prey up to 1 km away.
The Arctic is warming twice as fast as the global average melting the sea ice that is vital to the polar bears’ ability to find food.The polar bear’s food supply is directly impacted by the melting ice.Seals， their main meal， also breed on the ice.So the whole seal population dwindles too as a consequence of that change.And it has forced polar bears to look further for seals.This has increased conflict between humans and polar bears， as they come closer to human settlements looking for food.
The fight to save polar bears is in fact linked to the joint efforts of us humans.There are several organisations aimed to aid polar bears.Polar Bears International is the only conservation group aimed to help polar bears.Consisting of scientists and conservationists， they are expanding our knowledge about polar bears using the most advanced technology.Another is the International Association for Bear Research and Management （IBA）， a group with over 500 members from over 60 countries who work together to share research and information on eight bear species including the polar bear.
1.What puts the polar bear at risk？（ ）
A.Illegal hunting. B.Severe pollution.
C.Climate change. D.Invasive species.
2.What can we learn about the polar bear from Paragraphs 2 and 3？（ ）
A.They have a sharp sense of smell. B.They search for food in a small area.
C.They are poor at swimming. D.They live in harmony with humans.
3.Which is closest in meaning to “dwindle” underlined in Paragraph 3？（ ）
A.Expand. B.Decrease.
C.Recover. D.Disappear.
4.What is the author’s purpose in writing the text？（ ）
A.To introduce polar bears’ habitats and hunting skills.
B.To show the influence of climate change.
C.To display some conservation groups’ achievements.
D.To call on people to protect polar bears.
Ⅱ.阅读七选五
（2025·河南模拟预测）We often hear very bad statistics about the destruction of the Amazon.5.（ ） One Amazonian Indian tribe （部落） every year has disappeared since 1900.Unless something is done to prevent it， the Amazon will be totally destroyed in fifty years’ time.
6.（ ） Although it is being destroyed by big farmers and logging （伐木） companies， the biggest cause of its destruction is the cutting down of trees by thousands of small-scale farmers.7.（ ） They cut down trees of the rainforest to grow crops to make money.The soil of the Amazon is perfect for plants as long as there are trees.It is the trees that recycle the nutrients that make the Amazon suitable for growing food.When the farmers cut down the trees， the soil can only support crops for one or two years.8.（ ）
Logging is the second biggest cause of the destruction of the rainforest.A lot of the trees are taken for firewood， charcoal， or for making furniture.Not only are these trees destroyed， but the trees around them are also destroyed to make way for the roads and tracks needed to take the wood away.Large areas of forest have also been cut down to free land for cattle farming.9.（ ） And the ranchers （牧场主） move on.More trees will be sure to disappear because of their cattle.
Most of the rainforest lies within Brazil.Fortunately， it is beginning to bring more laws to protect its rainforest.
A.Again the land cannot support them for long.
B.So they have to move on， and cut down more trees.
C.The problem involves organizations and governments.
D.The trees are often considered important to big farmers.
E.Poverty forces people to leave the cities and look for land.
F.An area of rainforest， the size of Belgium， is cut down annually.
G.The true key factor causing damage to the rainforest is not as you imagine.
Ⅲ.读后续写
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。
（2025·海南一模）It was a lovely spring morning.The sky was blue， the sun was out， and the air was warm.As I drove along the curvy roads， I saw thousands of wild flowers in bloom and some volunteers picking up trash along the side of the road.I smiled as I saw them doing some “Spring Cleaning” for our Mother Earth and my mind was cast back to the spring day long long ago.
When my children were younger， we used to walk a small trail around the lake near our home.One spring day， my daughter and I noticed much trash was lying along the trail.The next day we brought a big trash bag with us and started to pick up the trash along the way slowly.There were pop cans， plastic water bottles， wrappers for candy bars， empty chip bags， pieces of broken fishing line， and even an old deserted shoe.We picked up each one and even fished a few pieces of garbage out of the water.By the time we had circled the lake， the bag was nearly full.
Tired but happy， we finally put the bag in an empty trash can.Before we headed home， we took one last look at the lake.It looked more beautiful than ever and I felt like the angels were smiling at us at that moment.
I realized that though environmental pollution is still serious， the truth is that every time we stop to pick up a single piece of trash， it will make a difference.So from then on I planned to take further action to keep the environment clean.
注意：1.续写词数应为150个左右； 2.请按如下格式作答。
When we were back home， my family discussed how to clear the rubbish regularly.
The following weekend， we put our plan into practice.
UNIT 5 A delicate world
Ⅰ.
语篇解读：本文是一篇说明文。文章介绍了北极熊受气候影响而生存数量下降，一些保护北极熊的组织正在努力使人们了解北极熊目前的处境以便更好地保护它们。1.C 细节理解题。根据第一段中的While they are not facing ...decline by 30% by 2050.可知，气候变化使北极熊处于危险之中。
2.A 推理判断题。根据第二段中的Polar bears have an incredibly well-developed sense of smell and can discover prey up to 1 km away.可推知，北极熊的嗅觉很灵敏。
3.B 词义猜测题。根据画线词上文可知，北极熊的食物供应直接受到冰川融化的影响。海豹是它们的主食，在冰上繁殖。因此，作为这种变化（受到全球变暖的影响北极熊的数量在减少）的一部分，整个海豹的数量也在减少。由此可知，画线词意为“减少，缩小”，与decrease的意思相近。
4.D 写作意图题。根据最后一段中的The fight to save polar bears ...to help polar bear.可推知，作者写本文的目的是号召人们保护北极熊。
Ⅱ.
语篇解读：本文是一篇说明文。文章主要介绍了亚马孙雨林遭到破坏的原因。 5.F 上文提到关于亚马孙雨林遭到破坏的糟糕统计数据，下文提到自1900年以来，每年都有一个亚马孙印第安部落消失。F项（每年有相当于比利时面积的热带雨林被砍伐）承上启下，符合语境。
6.G 根据下文可知，下文主要论述了森林被破坏的原因。G项（造成雨林被破坏的真正的关键因素并不像你想象的那样）引出下文，符合语境。
7.E 上文提到造成森林被破坏的最大原因是成千上万的小规模农户砍伐树木，下文提到砍伐雨林是为了赚钱，说明是贫困导致的。E项（贫困迫使人们离开城市去寻找土地）符合语境。
8.B 上文提到土壤只能支持农作物一到两年，说明接下来土壤无法使用。B项（农民不得不继续搬走，到另外的地方砍更多的树以获取土地种粮食）符合语境。
9.A 根据上文可知，大面积的森林被砍伐，腾出的土地用于养牛。根据下文可知，牧场主又得搬走，导致更多的树木被砍伐掉。A项（这片土地又不能长久地维持他们）符合语境，承接上文，与下文构成因果关系。
Ⅲ.
When we were back home， my family discussed how to clear the rubbish regularly.My daughter positively suggested that we should fix a time to do our cleaning.Considering the specific situation of each family member， we finally decided to clean up the garbage on the weekend.My younger son also made good suggestions， such as putting up signs to remind people to protect the environment.Both of my children were very excited about this plan.
The following weekend， we put our plan into practice.We set out with the signs we had made in advance and put them up as we picked up the trash.In this way， we hoped to remind people to pay attention to the environmental protection.It happened that on that day we ran into the same people who were willingly picking up the garbage last time.They spoke highly of our behavior.What’s more， they decided to join us and pick up the trash with us every weekend.Thus， our team was growing.

我很开心能代表人与自然和谐相处协会在这里发表演讲。
Last Sunday， our school organized a field trip to explore the wild
plants.We visited a nearby forest and learned about different types of
vegetation that exist there.
The significance of this activity cannot be overstated.It helped us
understand the importance of preserving our natural heritage.We learned
that every plant has its own unique habitat and inhabitant.If we disturb
their natural habitat， it can lead to erosion and chaos in the ecosystem.
Furthermore， we learned about the conservation of rare and
endangered plants.We were told that if we don’t take action soon，
these plants will disappear forever.
Generally， this activity was a great opportunity for us to learn about
the vast and mysterious world of plants.We owe it to ourselves and future
generations to protect our ecology and preserve our biological diversity.

Ⅰ.阅读理解
（2025·乐山三模）If someone asked you to name a species in need
of conservation， it wouldn’t take long for you to land upon the polar
bear.As the most symbolic animal of the Arctic， polar bears perfectly
adapt to such a tough environment.Although most are born on land，
polar bears spend the majority of their lives around water and on the sea
ice of the Arctic Ocean.While they are not facing upcoming extinction，
the destruction caused to their habitats by climate change puts their long-
term survival at risk and their numbers are predicted to decline by 30% by
2050.
It is estimated that there are 26，000 polar bears in the wild， living
across countries that border the Arctic Ocean.They are excellent
swimmers， able to reach a top speed of 6 mph.They have been known to
travel areas of up to 600，000 sq km to find their prey （猎物）.Polar
bears have an incredibly well-developed sense of smell and can discover
prey up to 1 km away.
The Arctic is warming twice as fast as the global average melting the
sea ice that is vital to the polar bears’ ability to find food.The polar
bear’s food supply is directly impacted by the melting ice.Seals， their
main meal， also breed on the ice.So the whole seal population dwindles
too as a consequence of that change.And it has forced polar bears to look
further for seals.This has increased conflict between humans and polar
bears， as they come closer to human settlements looking for food.
The fight to save polar bears is in fact linked to the joint efforts of us
humans.There are several organisations aimed to aid polar bears.Polar
Bears International is the only conservation group aimed to help polar
bears.Consisting of scientists and conservationists， they are expanding
our knowledge about polar bears using the most advanced
technology.Another is the International Association for Bear Research and
Management （IBA）， a group with over 500 members from over 60
countries who work together to share research and information on eight
bear species including the polar bear.

（2025·河南模拟预测）We often hear very bad statistics about the
destruction of the Amazon.5.（ ） One Amazonian Indian tribe （部

prevent it， the Amazon will be totally destroyed in fifty years’ time.
6. （ ） Although it is being destroyed by big farmers and
logging （伐木） companies， the biggest cause of its destruction is the
cutting down of trees by thousands of small-scale farmers.7.（ ）
They cut down trees of the rainforest to grow crops to make money.The
soil of the Amazon is perfect for plants as long as there are trees.It is the
trees that recycle the nutrients that make the Amazon suitable for growing
food.When the farmers cut down the trees， the soil can only support
crops for one or two years.8.（ ）
Logging is the second biggest cause of the destruction of the
rainforest.A lot of the trees are taken for firewood， charcoal， or for
making furniture.Not only are these trees destroyed， but the trees around
them are also destroyed to make way for the roads and tracks needed to

（2025·海南一模）It was a lovely spring morning.The sky was
blue， the sun was out， and the air was warm.As I drove along the curvy
roads， I saw thousands of wild flowers in bloom and some volunteers
picking up trash along the side of the road.I smiled as I saw them doing
some “Spring Cleaning” for our Mother Earth and my mind was cast
back to the spring day long long ago.
When my children were younger， we used to walk a small trail
around the lake near our home.One spring day， my daughter and I
noticed much trash was lying along the trail.The next day we brought a big
trash bag with us and started to pick up the trash along the way
slowly.There were pop cans， plastic water bottles， wrappers for candy
bars， empty chip bags， pieces of broken fishing line， and even an old
deserted shoe.We picked up each one and even fished a few pieces of
garbage out of the water.By the time we had circled the lake， the bag
was nearly full.
Tired but happy， we finally put the bag in an empty trash
can.Before we headed home， we took one last look at the lake.It looked
more beautiful than ever and I felt like the angels were smiling at us at that
moment.
I realized that though environmental pollution is still serious， the
truth is that every time we stop to pick up a single piece of trash， it will
make a difference.So from then on I planned to take further action to keep
the environment clean.

参考范文：
When we were back home， my family discussed how to clear the
rubbish regularly.My daughter positively suggested that we should fix a
time to do our cleaning.Considering the specific situation of each family
member， we finally decided to clean up the garbage on the weekend.My
younger son also made good suggestions， such as putting up signs to
remind people to protect the environment.Both of my children were very
excited about this plan.
The following weekend， we put our plan into practice.We set out
with the signs we had made in advance and put them up as we picked up
the trash.In this way， we hoped to remind people to pay attention to the
environmental protection.It happened that on that day we ran into the same
people who were willingly picking up the garbage last time.They spoke
highly of our behavior.What’s more， they decided to join us and pick
up the trash with us every weekend.Thus， our team was growing.
