14．-Roderick had an accident yesterday．
-How come？He      very carefully．（　�。�
A．droveB．drivesC．had drivenD．has driven

分析 ---Roderick昨天出車禍了．
---怎么會(huì)呢？他開車很小心的．

解答 答案：B
根據(jù)答語中"How come？"使用了一般現(xiàn)在時(shí)可知，此處描述的應(yīng)是現(xiàn)階段在通常的情況下，Roderick開車的特點(diǎn)即：他開車很小心；故應(yīng)使用一般現(xiàn)在時(shí)；A．一般過去時(shí)，表示過去發(fā)生的動(dòng)作；C．過去完成時(shí)，表示過去某時(shí)間之前發(fā)生的動(dòng)作；D．現(xiàn)在完成時(shí)，表示過去發(fā)生并持續(xù)到了現(xiàn)在的動(dòng)作；由于A．C．D都不符合句意，故選B

點(diǎn)評(píng) 本題考查了一般現(xiàn)在時(shí)態(tài)的用法．做類似的時(shí)態(tài)題時(shí)，首先要根據(jù)句意或句中的提示，判斷出動(dòng)作所發(fā)生的時(shí)間，從而確定句子應(yīng)使用的時(shí)態(tài)；其次應(yīng)熟練掌握各時(shí)態(tài)的意義及用法區(qū)別．

4．What is the porpose of readig or studying？If you can't remember what you read or study，it will be a waste of time．（36）GOne useful aid that does help you remember what you study is to have a specific purpose or reason for reading．
Why does a clerk in a store go away when your reply to her offer to help is，"No，thank you．I'm just looking．"？Both you and she know that if you aren't sure what you want，you are not likely to find it．But suppose you say instead，"Yes，thank you．I want a pair of sun glasses．"She says，"Right this way，please．"It's quite the same with your studying．If you choose a book，"just looking"for nothing in particular，you are likely to get just that-nothing．（37）FYour reasons will vary； they will include reading or studying"to find out more about"，"to understand the reasons for"and"to find out how"．
（38）ABefore you start to study，you say to yourself something like this，"I want to know why Stephen Vincent Benet happened to write about America"．Because you know why you are reading or studying，you relate the information to your purpose and remember it better．
Reading is not one single activity．（39）DAs you read，you take in ideas rapidly and accurately．But at the same time you express your own ideas to yourself as you react to what you read．You have a kind of mental conversation with the author．
This additional process of thinking about what you read includes evaluating it，relating it to what you already know，and using it for your own purposes （40）BOne part of critical reading，as you have discovered，is distinguishing between facts and opinions．Facts can be checked by evidence．Opinions are one's own personal reactions．Another part of critical reading is judging sources．Still another part is drawing accurate inferences．

A．This is an effective studying way．
B．In other words，a good reader is a critical reader．
C．You remember better when you know what you're reading．
D．At least two important processes go on at the same time．
E．It is important for students to have a positive attitude to their study．
F．But if you do know what you want，you are almost sure to get it．
G．Perhaps  you have already discovered some good ways to keep yourself from forgetting．

3．Mathilda，15，is Turkana，a native people that has survived by raising cattle in a semiarid （半干旱） region．Mathilda's school，like most schools in the area，doesn't have access to clean water and sanitation facilities for its students．So instead of spending their whole school day learning，Mathilda and her classmates start their day by spending two hours to the closest river fetching water---water that is anyway most likely not safe to drink．They do the same thing again in the afternoon，so they often lose around half of their school day fetching water．
Mathilda has to do the same thing outside of school hours to get the water her family needs at home，leaving her little time for studying．Because of rising temperatures，water has become harder and harder to find here，and people have to spend more and more time trying to find it．
This is just one small example of how climate change is making it harder to realize people's rights to water，education and security．Unfortunately，most higher-income countries remained silent on the issue．
This is despite studies showing that communities already facing marginalization（邊緣化），such as women and children，mostly suffer from climate change．This is especially the case for those in countries with limited resources and fragile ecosystems．
Meanwhile，women consist of the majority of the world's poor，and so are more dependent for their livelihood on natural resources that are threatened by climate change．And around the world，women and girls are the most likely to be responsible for fetching water for their families．
This exposes them to danger and leaves them with less time to attend school，earn money，or simply to rest．But the fact is that the effects of climate change will be felt globally．
Despite the difficulties she is facing，trying to get an education，Mathilda says she hopes to serve her community in a leadership role when she grows up．
"All of the world's leaders need to work together to solve this problem that we are all facing，"she said．
24．Mathilda has to spendCfetching water every school day．
A．two hours  
B．four hours   
C．more than four hours    
D．a(chǎn)lmost a whole day
25．The first two paragraphs are intended to tell usB．
A．the cause and effect of lack of water  
B．one serious consequence of climate change
C．the difficulties in fetching water in the semiarid region
D．the hardship of life for the people in the semiarid region
26．We can conclude from the passage thatA．
A．climate change is everyone's business
B．water is becoming rare because of rising temperatures
C．fetching water takes up Mathilda's half of studying time
D．females are more responsible for fetching water for their families
27．The passage is mainly about the problem caused byC．
A．rising temperatures       
B．fetching water   
C．climate change   
D．water shortage．
