8．-Why do you look so worried？
-My computed broke down and my paper_____unfinished since．（　�。�
A．was leftB．has leftC．leftD．has been left

分析 --你怎么看起來那么焦急呀？
--我的電腦壞了，我的論文還沒有寫完呢！

解答 答案：D．
根據(jù)句中的時間狀語since可知，此處應(yīng)該指的是since my computer broke down，所以需要使用現(xiàn)在完成時，而my paper與unfinish之間為邏輯上的動賓關(guān)系，所以要用被動結(jié)構(gòu)，實際上本題考查短語leave my paper unfinished；故選D．

點評 對于動詞時態(tài)的考查要搞明白每個時態(tài)的具體用法，尤其是要熟悉一些時態(tài)中的典型時間狀語．

3．Styrofoam，or polystyrene，is a light-weight material，about 95 percent air，with very good  insulation（隔熱） properties，according to Earthsource．org．It is used in products from cups that  keep your drinks hot or cold to packaging material that protects items during shipping．
    With the above good features，Styrofoam still enjoys a bad reputation．It cannot be recycled  without releasing dangerous pollution into the air．The U．S．Environmental Protection Agency says it is the fifth-largest creator of harmful waste．
    But now the common worms which are usually disgusting can come to the rescue，specifically，mealworms．Scientists from the U．S．a(chǎn)nd China have discovered that mealworms can digest plastic．One mealworm can digest a pill-sized amount of plastic a day．Study co-author Wei-Min Wu says that in 24 hours，the plastic is turned into carbon dioxide．
   Since Styrofoam has no nutrition at all，are the worms hurt by eating plastic？Much to the scientists'surprise，the study found that worms eating Styrofoam were as healthy as worms eating bran（谷糠）．
    The researchers will study the worm's eating habits and digesting system，looking to copy the plastic breakdown but on a larger scale．Once the way can be put into practice，it will make a revolutionary difference to the disposal of plastic．
"Solving the issue of plastic pollution is important"，says Wu，a Stanford University environmental engineering instructor．After all，our earth is small and landfill space is becoming limited with too much garbage waiting to be dealt with，he says．
    About 33-million tons of plastic are thrown away in the United States every year．Plastic plates，cups and containers take up 25 percent to 30 percent of space in America's landfills．One Styrofoam cup takes more than 1 million years to recycle in a landfill，according to Cleveland State University．

66．What do we know about Styrofoam？C
A．It can be used to cool drinks．
B．It is a weightless material．
C．It is harmful when recycled．
D．It is usually used on ships．
67．What can we infer from the third paragraph？A
A．Mealworms have amazing digesting power．
B．Mealworms are not bad in their nature．
C．Mealworms can rescue people's lives．
D．People misunderstood mealworms in the past．
68．Why will researchers study the worm's eating habits and digesting system？B
A．To find ways to help mealworms grow larger．
B．To imitate their ways of breaking down plastic．
C．To help develop their digesting ability．
D．To make sure of their safety after eating plastic．
69．In the future，plastic may be recycledD．
A．by raising amounts of mealworms    
B．by environmental engineering instructors
C．using a method inspired by eating mealworms 
D．without sending out dangerous pollution
70．What's the main idea of this passage？C
A．Styrofoam is widely used in daily life．
B．Mealworms are genius at eating plastic．
C．Plastic recycling may be no more a problem．
D．Plastic can be turned into carbon dioxide．

13．From the health point of view we are living in an amazing age．We are free from  many of the most dangerous diseases．A large number of once deadly illnesses can now be cured by modern medicine．It is almost certain that one day medicines will be found for the most stubborn remaining diseases．The expectation of life has increased greatly．But though the possibility of living a long and happy life is greater than ever before，every day we witness the unbelievable killing of men，women and children on the roads．Man vs the motor-car．It is a never-ending battle which man is losing．Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen．
   It has been rightly said that when a man is sitting behind a steering wheel（方向盤），his car becomes the extension of his personality．There is no doubt that the motor-car often brings out a man's very worst qualities．People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel．They say，they are ill-mannered and aggressive，willful as two-years-olds and completely selfish．All their hidden angers and disappointments seem to be brought to the surface by the act of driving．
   The surprising thing is that society smiles so gentlly on the motorist and seems to forgive his behavior．Everything is done for his convenience．Cities are allowed to become almost uninhabitable because of heavy traffic； towns are made ugly by huge car parks； the countryside is ruined by road networks； and the deaths become nothing more than a number every year，to be easily forgotten．
   It is high time a world rule was created to reduce this senseless waste of human life．With regard to driving，the laws of some countries are unbelievably lax（不嚴格） and even the strictest are not strict enough．A rule which was universally accepted could only have an obviously beneficial effect on the accident rate．Here are a few examples of some of the things that might be done．The driving test should be standardlized and made far more difficult than it is； all the drivers should be made to take a test every three years or so； the age at which young people are allowed to drive any vehicle should be raised to at least 21； all vehicles should be put through strict tests for safety each year．Even the smallest amount of alcohol in the blood can damage a person's driving ability．Present drinking and driving laws （where they exist） should be made much stricter． Speed limits should be required on all roads．Governments should lay down safety specifications for car factories，as has been done in the USA．All advertising stressing power and performance should be banned．These measures may not sound good enough．But surely nothing should be considered as too severe if it results in reducing the number of deaths．After all，the world is for human beings，not motor-cars．

51．What is the main idea of this passage？C
A．Traffic accidents are mainly caused by motorists．
B．Thousands of people the world over are killed each year．
C．Only stricter traffic laws can prevent accidents．
D．The laws of some countries about driving are too lax．
52．What does the author think of society toward motorists？B
A．Society laughs at the motorists．
B．Society forgives their rude driving．
C．Victims of accidents are nothing．
D．Huge car parks are built in the cities and towns．
53．What does the author say"his car becomes the extension of his personality"in Para.2？D
A．Driving can represent his manners．
B．Driving can show the other part of his personality．
C．Driving can bring out his character．
D．Driving can show his hidden qualities．
54．Which of the followings is NOT mentioned as a way against traffic accidents？A
A．Build more highways．
B．Stricter driving tests．
C．Test drivers every three years
D．Raise age limit and lay down safety specifications．
55．The author's attitude towards the present traffic situation isA
A．unsatisfied

20．What picture do you have of the future？Will life in the future be better，worse or the same as now？What do you hope about the future？
  Futurologists predict that life will probably be very different in 2050 in all the fields of activity，from entertainment to technology．First of all，it seems that TV channels will have disappeared by 2050．Instead，people will choose a program from a"menu"and a computer will send the program directly to the television．By 2050，music，films，programs，newspapers and books will come to us by computer．
   In what concerns the environment，water will have become one of our most serious problems．Demand for water will increase ten times between now and 2050 and there could be serious shortages．Some futurologists predict that water could be the cause of war if we don't act now．In transport，cars will run on new，clean fuels and they will go very fast．Cars will have computers to control the speed of the car and there won't be any accidents．Today，many cars have computers that tell drivers exactly where they are．By 2050，the computer will control the car and drive it to your destination．
  In the domain（領(lǐng)域）of technology，robots will have replaced people in factories．Many factories already use robots．Big companies prefer robots-they do not ask for payrises or go on strike，and they work 24 hours a day．By 2050，we will see robots everywhere-in factories，schools，offices，hospitals，hops and homes．
  Last but not least，medicine technology will have conquered many diseases．Today scientists have discovered how to control genes．They have already produced clones of animals．By 2050，scientists will be able to produce clones of people and decide how they look，how they behave and how much intelligence they have．Scientists will be able to do these things-but should they？

61．What's the purpose of the first paragraph？A
A．To arouse the interest of the readers．

17．Have you ever seen any students whose trousers hang so low you can see their underwear？What do you think of that？Fashionable？Some of today's teenagers are big fans of such a look．（36）A．
The headmaster of a school in central Italy has asked students to stop wearing low-rise jeans that expose underwear and part of the body．His request came after a class trip．One day，he saw one boy's baggy trousers slide to his feet．（37）C．
But in Italy，a nation that takes fashion very seriously，the suggestion caused a debate among parents，teachers and students．The issue is whether the headmaster's request will limit students'freedom-or whether dress in Italian schools is too casual．
（38）B．"We do not want to kick fashion out．"the headmaster explained，"but extremes of fashion like this are not right in school．"Many other schools have now requested that their students also stop wearing such trousers．
（39）F．Ludovica Gaudio，14，wore extremely low trousers exposing orange underwear in class．It was cold，so she wore a matching orange scarf．（40）E．"I don't really feel comfortable in those sorts of jeans，"said Sarah Lattanzi，"in winter，when dressed like that，it's quite cold and I am afraid my stomach will ache．"

A．But recently this trend has been at the center of an argument in Italian middle schools．
B．A parents'group praised the move in favor of good taste，while others advised schools to stop worrying about fashion and fix up old school buildings．
C．He pointed out that this way of dressing is not suitable for school．
D．Most students have simply ignored the request．
E．Another 14-year-old said she would probably respect the request，simply for practical reasons．
F．Let us see that Italian students react differently to schools'requests．
G．Schools should pay attention to things more important than students'clothes．
