7．An accident in a bicycle race in the United States eight years ago alerted James Chang to the importance of sports medicine．One of his riding companions（25）was injured（injure） severely in the accident．
From then on，Chang，45，a Chinese-American who was born in Anhui province，began to launch business relating to physical safety and medical assistance，particularly in sport．So（26）whenhe took up marathon running two years ago he was shocked to see frequent injuries，many of them avoidable．
"I always heard people talking about people in marathons in China dying suddenly，"he says，adding that one reason why many of these deaths happen is（27）thatthere is a lot of ignorance in China about what marathon running involves．
Many amateur runners in China who are highly competitive get carried away and run at a pace that is far in excess of（28）whatthey can expect their body to take，and even ignore clear signals such as pain，Chang says．
As Chinese have placed more emphasis on leading healthy life-styles in recent years，marathon and other long-distance running（29）have become（become） a highly popular sport across the country quickly．
More than 50 China Athletic Association-sanctioned urban marathons were held in the country last year，and 39 races involving more than 750，000 runners were held the year before．However，long-distance running is a serious business that can exact a heavy physical toll on runners．
"Marathon carries（30）higher（high） risks of injury than other forms of sport，"Hou says，adding that the key to avoiding injury is to strengthen the body through regular exercise and to be aware of one's own physical condition．
Although some chronic injuries are hard（31）to avoid（avoid），even for highly experienced runners，cramp，fainting and shock can easily be prevent（32）ifrunners better understand the sport，he says．

分析 本文作者主要講述了45歲的美籍華人James Chang在體育運(yùn)動(dòng)方面開展與身體安全和醫(yī)療援助相關(guān)業(yè)務(wù)的起因；對(duì)中國(guó)賽跑選手現(xiàn)狀的分析以及長(zhǎng)跑運(yùn)動(dòng)在中國(guó)受歡迎的程度；并重點(diǎn)講述了James Chang對(duì)于參加馬拉松以及其他長(zhǎng)跑運(yùn)動(dòng)的運(yùn)動(dòng)員們避免該運(yùn)動(dòng)所造成傷害的方法；James Chang認(rèn)為，在中國(guó)，有人參加完馬拉松賽跑猝死的原因之一是由于人們對(duì)涉及到馬拉松賽跑的很多事情都不了解；中國(guó)許多的業(yè)余賽跑選手忘乎所以的參與到比賽中去，這遠(yuǎn)遠(yuǎn)超出了他們期待自己的身體所能承受的東西，甚至忽略了身體所發(fā)出的清晰的信號(hào)，如疼痛；在中國(guó)各地，馬拉松以及其他長(zhǎng)跑運(yùn)動(dòng)已迅速成為了一種很受歡迎的體育運(yùn)動(dòng)；與其他形式的運(yùn)動(dòng)相比，馬拉松比賽會(huì)帶來更高風(fēng)險(xiǎn)的傷害；避免傷害的關(guān)鍵是通過經(jīng)常鍛煉，并意識(shí)到自己的身體狀況，以加強(qiáng)身體鍛煉；另外，如果賽跑選手們能更好地了解這項(xiàng)運(yùn)動(dòng)，也可以防止抽筋，昏厥和休克等情況的發(fā)生．

解答 25．was injured        考查被動(dòng)語態(tài)    此處的主語"One of his riding companions"與動(dòng)詞injure構(gòu)成被動(dòng)關(guān)系；本句意為：他的一個(gè)騎行同伴在事故中遭受了重傷；根據(jù)上一句可知，這里講述的是8年前的事情；故用一般過去時(shí)態(tài)的被動(dòng)語態(tài)was injured．       
26．when     考查從屬連詞       分析句意可知，此處引導(dǎo)的應(yīng)是時(shí)間狀語從句；意為：因此，當(dāng)他兩年前參加馬拉松比賽時(shí)，他震驚地看到了頻繁的受傷，其中許多是可以避免的；故填when．
27．that      連詞that        此處用在系動(dòng)詞is之后，引導(dǎo)表語從句；由于該從句不缺少任何成分并且表達(dá)了完整的意思，"在中國(guó)，人們對(duì)涉及到馬拉松賽跑的很多事情都不了解"； 故用連詞that．
28．what     考查連接代詞      此處用在介詞短語 in excess of之后，故本句是賓語從句；意為：他們期待身體所能承受的東西；此處在句中作take的賓語，意為"…的東西"；故填連接代詞what．
29．have become     考查時(shí)態(tài)     根據(jù)句意以及句中的時(shí)間狀語"in recent years"可知，此處表達(dá)的是馬拉松以及其他長(zhǎng)跑運(yùn)動(dòng)對(duì)現(xiàn)在所產(chǎn)生的影響：即它們迅速在全國(guó)各地成為一個(gè)很受歡迎的體育運(yùn)動(dòng)，故用現(xiàn)在完成時(shí)；由于主語"marathon and other long-distance running"指的是馬拉松以及其他長(zhǎng)跑運(yùn)動(dòng)；故用have become．     
30．higher    考查形容詞的比較級(jí)        根據(jù)句意"馬拉松比賽與其他形式的運(yùn)動(dòng)相比會(huì)帶來更高風(fēng)險(xiǎn)的傷害"以及句中的連詞"than"可知，這里表達(dá)的是兩者的比較；故用形容詞的比較級(jí)higher．
31．to avoid     考查固定短語        固定短語be hard to do sth．意為：難于做某事；故填to avoid．    
32．if    考查連詞    根據(jù)最后一句的句意"即使對(duì)非常有經(jīng)驗(yàn)的運(yùn)動(dòng)員來說，雖然一些慢性損傷是難以避免的，但是如果賽跑選手們能更好地了解這項(xiàng)運(yùn)動(dòng)，抽筋，昏厥和休克是可以防止的"可知，此處引導(dǎo)的是條件狀語從句；故填if．

點(diǎn)評(píng) 本題主要考查了各種語法在短文中的具體運(yùn)用．做本題時(shí)，需要在正確理解短文的前提下，逐句分析句意以及所考查到的語法現(xiàn)象；因此在平時(shí)的學(xué)習(xí)中，應(yīng)熟練掌握各種語法知識(shí)，其中包括詞法，句法，各種時(shí)態(tài)語態(tài)以及虛擬語氣等．

17．Fast food and too much TV time should not take all the blame for the weight problems．A group of researchers say that a number of aspects of modern living from lack of sleep to environmental chemicals and to living with air conditioning-may be closely related to the weight problems of many people．
Lack of sleep is one of factors．Researches in animals and humans suggest that a lack of sleep over a long time can increase appetite．Studies also show that many adults and children are sleeping less than they used to．In recent decades，adults have gone from sleeping for all average of nine hours to about seven hours．
There is also evidence that industrial chemicals may increase body fat．These chemicals，which are used in products，change hormonal（荷爾蒙的） activity when they get into the body．Studies suggest that people have been getting more and more of these chemicals through the food chain in recent decades．
Another factor that may be making people overweight is air conditioning．The body burns calories when forced to eat less in hot and wet weather，but air conditioning makes it unnecessary for the body to make any adjustment．
Researchers also list other possible risk factors for overweight，including more older mothers，whose children may become overweight more easily； a number of medicines which can lead to weight gain； and fewer people who smoke，since people often gain weight when they stop smoking because nicotine can make people eat less．
No one is suggesting that people should stop working and sleep more，or keep smoking．When it comes to saying any person's weight，what really matters is how much they eat and how much of the food they use every day．That means diet and exercise are still the key．

81．Why does lack of sleep will result in weight problem？（No more than 5words）Because it can increase appetite．
82．How long do adults averagely sleep nowadays？（No more than 2words）Seven/7 hours．
83．How do the industrial chemicals affecting our weight come into our body？
（No more than 4words）Through the food chain．
84．What is the main idea of this passage？（No more than 18words）A number of aspects of modern living may be closely related to the weight problems of many people．

18．Smoggy weather has become common in China．But these days，air pollution levels in the north eastern city of Harbin surpassed the previous record levels．
The city was essentially shut down after PM2.5，fine Particulate（微粒物） pollution that is considered hazardous（有害的）．reached levels of 1000micrograms per cubic meter-40times the safety level remended by the World Health Organization．Schools，motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10meters．
Photos from Harbin showed residents covering their mouths with masks and scarves，and moving like ghostly shadows through the fog．Cars and motorcycles are moving slowly as traffic came to a standstill with traffic lights barely visible．．
Just days previously，the World Health Organization's International Agency for Research on Cancer （IARC）  classified air pollution as a carcinogen（致癌物）．It stated that there  is"sufficient evidence"that exposure to outdoor air pollution causes lung cancer and also linked it with an increased risk of bladder cancer．It's said that exposure has increased significantly particularly in"rapidly industrial countries with large populations"．
"The air we breathe has become polluted with a mixture of cancer-causing substances"，Dr Kurt Straif，head of the IARC said in a press released．"We now know that outdoor air pollution is not only a major risk to health in general，but also a leading environmental cause of cancer deaths．"
On the Chinese social media site Weibo，many users complained about the pollution and shared their concerns．References to"feed people with smog"have become popular on Weibo and there is a sarcastic play on the expression"serve the people"，as the two have a similar pronunciation．
"The impact of air pollution on people will be gradual．There won't be a sudden outbreak of symptoms，but normally three to five days after the smoggy weather occurs，there is a peak in the number of people seeing doctors，"Deng Ying，a doctor at the Second Affiliated Hospital of Harbin Medical University was quoted as saying．

24．As thick smog has become a common scene in Harbin，D
A．students there can go to school as usual
B．residents in the city can see as far as 20meters
C．traffic lights can be easily visible
D．the urban traffic has been seriously influenced
25．When exposed to outdoor air pollution，what kind of disease can be caused？C．
A．Cancer of stomach  B．Breast cancer  C．Bladder cancer     D．Ovarian cancer
26．According to Dr Kurt Straif，we can learn thatB．
A．the effect of the．smoggy weather is gradual
B．a(chǎn)ir pollution is the man environmental cause，of cancer deaths
C．exposure has greatly increased in countries with large populations
D．"feed people with smog"has bee a hot word
27．The purpose of this passage is toA．
A．a(chǎn)waken people's environmental awareness
B．warn people not to go out in smoggy weather
C．call for the public to wear their masks

4．Among all the fast growing science and technology，the research of human genes，or biological engineering as people call it，is drawing more and more attention now．Sometimes it is a hot topic discussed by people．
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with，such as cancer and heart disease．Every year，millions of people are murdered by these two killers．And to date，doctors have not found an effective way to cure them．But if the gene technology is applied，not only these two diseases can be cured completely，bringing happiness and more living days to the patients，but also the great amount of money people spend on curing their diseases can be saved，therefore it benefits the economy as well．In addition，human life span（壽命） can be prolonged．
Gene technology can help people to give birth to healthy and clever children．Some families，with the English imperial family being a good example，have hereditary（遺傳的） diseases．This means their children will for sure have the family disease，which is a great trouble for these families．In the past，doctors could do nothing about hereditary diseases．But gene technology can solve this problem perfectly．The scientist just need to find the wrong gene and correct it，and a healthy child will be born．
Some people are worrying that the gene research can be used to manufacture human beings in large quantities．In the past few years，scientists have succeeded in cloning a sheep，therefore these people predict that human babies would soon be cloned．But I believe cloned babies will not come out in large quantities，for most couples in the world can have babies in very normal way．Of course，the government must take care to control gene technology．

66．What does"these two killers"in the second paragraph refer to？C
A．Gene technology and another treatment of the two diseases．
B．The two murderers who killed the cloned baby．
C．The two diseases of cancer and heart disease．
D．Hereditary diseases and cancer．
67．What's the main idea of the third paragraph？A
A．How gene technology can be applied in the field of treating hereditary diseases．
B．Gene technology can be used to clone human babies．
C．Gene technology can help people to give birth to a baby．
D．Gene technology can help the English imperial family out．
68．In what way gene technology can help to treat hereditary diseases？B
A．Using gene technology，people with hereditary diseases can have more living days．
B．Using gene technology，the scientist finds the wrong gene and corrects it．
C．Using gene technology，human babies can be cloned．
D．Doctors can cure cancer and heart disease with the help of gene technology．
69．What is the main purpose of writing this passage？A
A．Expressing the writer's idea that gene technology will benefit people．
B．Telling people the disadvantages of gene technology．
C．Telling the readers that gene technology will not benefit people．
D．Explaining that gene technology will also do harm to the humanity．
