A few months ago，the Brooklyn Nets basketball player Ben Simmons donated a basketball court to Machang township in Southwest China's Guizhou Province during a ceremony.Simmons has visited China several times since he was young.He has been deeply touched by the Chinese people's warmth and friendly feelings towards him and their enthusiasm for basketball.
Impressed by the news that basketball competitions had been held in Guizhou at a village with their own “Village Basketball Association (VBA)”， Simmons decided to donate a basketball court to the village during the Chinese New Year Basketball Competition in January.After conducting a survey，he set up the basketball court in Machang township in Gui'an New Area in the hope that it would create more opportunities for young fans to play basketball.
In the mountainous village of Machang，there are no huge electronic screens or advertisements at basketball games，but they can still be thrilling thanks to local players' love for the sport.These players later became a hit in China and even went viral (迅速传播).A recent final competition attracted 30，000 viewers on site and more than 1 billion viewers online.
Comparatively，the NBA boasts the best players in the world，top-class basketball gyms and professionally made commercials，so its exciting games draw fans around the world.The NBA and the “VBA” are thousands of miles apart，but their games are equally striking，fueling thousands of fans' enthusiasm.Both focus on a common interest of basketball fans in the U．S.and China and their shared pursuit of sports and a better life.
Although Machang township lacks modern sports facilities，the local people's love for basketball remains strong.So Simmons' donation will surely help improve the village's situation to a certain extent，but more importantly，it will bring people separated by the Pacific Ocean closer through this sport.
4．How did Ben Simmons give a hand to Machang township
A．By donating electronic screens and some equipment for playing basketball.
B．By giving some money to help the township to build a stadium.
C．By training some local people to practise playing basketball.
D．By offering a basketball court to the township for free.
5．What can we learn from the third paragraph
A．The recent match appealed to a large number of viewers.
B．The local players can earn an amount of money by playing the game.
C．The players' professional skills make the local basketball games exciting.
D．Advertisements contributed to the successful promotion of the local sport.
6．Why is the NBA mentioned in paragraph 4
A．To suggest the “VBA” should learn from the NBA.
B．To show the NBA is much more exciting than the “VBA”．
C．To express the NBA and the “VBA” have something in common.
D．To prove the rules of the “VBA” and the NBA are almost the same.
7．What can be the theme of the last paragraph
A．The living standard of the village.
B．The significance of the donation.
C．The sports facilities of the township.
D．The meaning of the basketball competitions.

Migraine is a disease that has a number of symptoms (症状)，including head pain that can stick around from four hours to several days.While migraines can happen partly because of genetic (基因的) problems，attacks may happen by chance，set off by a cause in the environment.
One common cause is food，and some common dietary causes include alcohol，salt，sugar，chocolate，and caffeine.But there are many others，and scientists continue to identify more. For example，a Brazilian study found that watermelons brought on a headache within minutes in about 30 percent of the participants.
Some new research is looking at which foods and what kinds of diets can prevent or lessen migraines.A new study published by a team of researchers found that a diet higher in fish oils rather than vegetable oils helped people ease their headaches.In the study，those on a diet lower in vegetable oil and higher in fatty fish had a 30 to 40 percent reduction in total headache hours per day，serious headache hours per day，and overall headache days per month compared to the control group.
Tanya Kamka had suffered weekly migraines for most of her life.Then，in her 50s，she joined the NIH diet experiment and increased her intake of fish.After only a few months，“I haven't had a migraine，not even a mild one，in over two years，” she says.
For others，the solution comes from plants，not fish.A 60-year-old man joined a study on the food-migraine link and turned to a diet，which includes a lot of dark，leafy greens.After two months he was experiencing only one migraine a month instead of the 18 to 24 a month he'd suffered before.
Clearly，people with migraines react to food in very different ways.What works for one person may not work for another.
8．What do we know about migraine from paragraph 1
A．It is related to sleep time.
B．It never runs in the family.
C．It lasts for at least three hours.
D．It can be caused by the environment.
9．What is paragraph 2 mainly about
A．The length of migraine.
B．Foods that lead to migraine.
C．The most common cause of migraine.
D．A Brazilian study about migraine.
10．What can lessen migraines according to a new study
A．Fish oils.　　　　 B．Vegetable oils.
C．All kinds of fat. 　 D．Various vegetables.
11．Which is the author's opinion about the effect of food on migraines
A．It varies from person to person.
B．It can only stay for a short time.
C．It depends on the age of a patient.
D．It is connected to how much one takes.
D
Going from being called a “stupid molecule (分子)” to “the secret of life”， our discovery and understanding of DNA has come a long way.Last year marks the 70th anniversary of the discovery of the structure of DNA—the pivotal (关键的) year when the so-called “secret of life” was uncovered by two scientists: James Watson from the U．S. and Francis Crick from the UK.
Inherited characteristics like eye color，nose shape and even intelligence—scientists found the structure of the chemical which transmits these from one generation to another.“Discovering how these ‘chemical’ cards are shuffled (洗牌) and paired will keep the scientists busy for the next 50 years，” journalist Ritchie Calder commented in 1953 on the discovery.And it certainly has.The study of DNA has led to world-changing advances in many fields.
“DNA makes time fluid (流动的)，” said The Irish Times.It lets us redefine the future.For example，in medicine，DNA helps us identify “weak points” in the human genome that might be prone to disease.Through a technique called gene therapy，a person's genes can be modified to treat or cure certain diseases.Another example is agriculture，where work on plant DNA has allowed us to change the way we breed (培育) crops，opening the door for genetically modified plants and advances in food security.
DNA can also shed light on the past.In forensic (法医的) science，DNA analysis has come to serve as a vital form of evidence in crime scenes，with “many millions having been proven guilty or innocent” through its usage，said the website AZoLife Sciences.And DNA in specimens (标本) like fossils and artifacts (文物) can give us vital information on humans and other species.
But what's next for DNA research Improvements in technology are allowing us to utilize DNA in new ways.As the cost of DNA technologies decreases and related machines become more efficient，it becomes more accessible，reported Wired magazine.In medicine，DNA plays a key role in furthering the development of “personalized medicine” — designing treatment plans based on the genomes and other specific factors of individual patients.As “natural supercomputers”， DNA can store large amounts of data.So scientists are busy learning from DNA to make our computers store more data and work even faster.
12．Why does the author quote Ritchie Calder's remark in paragraph 2
A．To help better understand DNA.
B．To highlight scientists' efforts.
C．To stress the discovery's impact.
D．To stress the importance of DNA technology.
13．What are paragraphs 3 and 4 mainly about
A．The diverse applications of DNA.
B．The mysterious aspects of DNA.
C．Challenges of DNA research.
D．Ways to expand DNA research.
14．What does the underlined word “utilize” in paragraph 5 probably mean
A．Protect. 　 B．Use.
C．Correct. 　 D．Prevent.
15．What could DNA research help with in the future according to the text
A．The replacement of medicines.
B．The reduction of medical costs.
C．The advancement of self-diagnosis.
D．The improvement of computer performance.

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。
A few years ago，my wife Sue had some fairly serious health problems.She had suffered surgery after surgery and had also put on weight for several years.Diets had not helped her.
One day we sat down and drew up a “wish list” of the things we wanted most out of life.One of Sue's items was to run in a marathon.Given her history and physical limitations，I thought her goal was completely unrealistic，but Sue became committed to it.
She began by running very slowly around.Every day she ran just a little farther than she had the day before，just one driveway more.“When will I ever be able to run a mile？” Sue asked one day.Soon she was running three.Then five.“We can change ourselves for the better and cause ourselves to pursue our most precious desires with almost total success，” Sue said and registered to run in the St.George Marathon in southern Utah.
I drove the mountainous road from Cedar City to St.George.When the marathon began，I parked the car near the finish line and waited for Sue to come in.Five hours later，it was raining steadily and the wind was cold.Several cold and injured runners had been transported past me，and I began to panic.The image of Sue，alone and cold，off the road somewhere，made me sick with worry.The fast and strong competitors had finished long ago，and runners were becoming fewer and fewer.Now I could not see anyone in either direction.
Almost all of the cars along the marathon route had left，and some normal traffic was beginning.I was able to drive directly up the race route.There were still no runners in view after driving almost two miles.Then I went around a bend in the road and spotted two runners running up ahead.
注意：1．续写词数应为150左右；

[参考范文]
Dear David，
I am Li Hua, the monitor of Class 6 Grade 2．Knowing more sports events will be carried out in our extra-curricular activities, I'd like to recommend two events on behalf of my class.
Most of us consider jogging is suitable for both boys and girls.Not only will it benefit our health，but also it is helpful to shape our body.As for the group game, football is much more popular than others, especially among boys.All the members learn to cooperate with each other so that they build up important qualities like responsibility and teamwork.For these reasons, it's highly recommended that jogging and football should be included.
Hopefully, our recommendation will be taken into consideration.
Yours，
Li Hua

[参考范文]
It was Sue in the company of a girl runner, struggling. As I approached them, I noticed the pair dragging their feet and running forward awkwardly with their shoes wet.I pulled off and called.“Are you okay？” “Oh, yes！” Sue said, almost out of breath.The girl also nodded and kept moving.I had wanted to offer them a ride in, but the resolve in their eyes made me swallow back the words.I turned around and followed.Inch by inch, they were getting closer to the finish line.Eventually, the real winners in my heart ran past the finish line.
At the finish line, the girl hugged Sue, “You made me believe we could do it.” She added, “Sue described so vividly how it would be to finish that I knew I could do it.” Sue smiled back.“I've been dreaming about this day for two years and I shall not be denied.”Greatly moved, the girl promised she would never quit anything easily without total success.At that moment, I looked at Sue and found she was carrying herself differently.It was not as if she had become someone new; it was more as if she had discovered a real self she had not known before.She truly liked her newly discovered self.So did I.

37．to recycle　[考查非谓语动词。空处应填动词不定式作后置定语，修饰抽象名词efforts，故填to recycle。]
38．significantly　[考查副词。空处修饰动词contributed，应用副词形式，故填significantly。]
39．being generated　[考查非谓语动词。prevent... from doing sth.“阻止……做某事”，空处应填动词-ing形式作宾语，且动词generate和waste之间是被动关系，故用被动式，故填being generated。]
40．has established　[考查时态和主谓一致。根据时间状语Over the past decade可知，句子时态用现在完成时，主语China表示单数意义，助动词应用has，故填has established。]
41．largest　[考查形容词最高级。根据空前的“the”以及空后的“in the world”可知，此处应用形容词最高级，故填largest。]
42．the　[考查冠词。此处是倍数表达法“数字＋times＋the＋名词”，故填the。]
43．contributions　[考查名词复数。contribution“贡献”，是可数名词，make great contributions“做出巨大贡献”，此处应用名词复数形式，故填contributions。]
44．which　[考查定语从句。分词句子可知，此处是非限制性定语从句，先行词是“imported plastic waste”，关系词在从句中作介词of的宾语，应用关系代词which，故填which。]
45．helped　[考查时态。结合上文内容可知，此处是描述过去发生的事情，应用一般过去时，空处是谓语动词，用过去式。故填helped。]
