5．Five years ago，David Smith wore an expensive suit to work every day．"I was a clothes addict，"he jokes．"I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled．"Today David wears casual clothes-khaki pants and sports shirt-to the office．He hardly ever wears a necktie．"I'm working harder than ever，"David says，"and I need to feel comfortable．"
More and more companies are allowing their office workers to wear casual clothes to work．In the United States，the change from formal to casual office wear has been gradual．In the early 1990s，many companies allowed their employees to wear casual clothes on Friday，but only on Friday．This became known as"dress-down Friday"or"casual Friday"．"What started out as an extra one-day-a-week benefit for employees has really become an everyday thing．"said business consultant Maisly Jones．
Why have so many companies started allowing their employees to wear casual clothes？One reason is that it's easier for a company to attract new employees if it has a casual dress code．"A lot of young people don't want to dress up for work，"says the owner of a software company，"so it's hard to hire people if you have a conservative （保守的） dress code．"Another reason is that people seem happier and more productive when they are wearing comfortable clothes．In a study conducted by Levi Strauss Company，85 percent of employers said that they believe that casual dress improves employee morale（士氣）．Only 4 percent of employers said that casual dress has a negative effect on productivity．Supporters of casual office wear also argue that a casual dress code helps them save money．"Suits are expensive，if you have to wear one every day，"one person said．"For the same amount of money，you can buy a lot more casual clothes．"
28．David Smith refers to himself as"a clothes addict，"becauseC．
A．he often wore khaki pants and a sports shirt
B．he couldn't stand a clean appearance
C．he wanted his clothes to look neat all the time
D．he didn't want to spend much money on clothes
29．David Smith wears casual clothes now，becauseA．
A．they make him feel at ease when working
B．he cannot afford to buy expensive clothes
C．he looks handsome in casual clothes
D．he no longer works for any company
30．According to this passage，which of the following statements is TRUE？C
A．Company workers started to dress down every day about twenty years ago．
B．Comfortable clothes make employees more productive．
C．Dress-down has become an everyday phenomenon since the early 1990s．
D．Many workers want to wear casual clothes to impress people．
31．In this passage，the following advantages of casual office wear are mentioned exceptB．
A．saving employees'money             
B．making employees more attractive
C．improving employees'motivation     
D．making employees happier．

29．A．細節(jié)理解題．從第 1 段最后一句話"I'm working harder than ever，"David says，"and I need to feel comfortable．"可知David Smith現(xiàn)在穿休閑服，因為他們讓他安心工作時；故選A．
30．C．細節(jié)理解題．從第 2 段最后 1 句"What started out as an extra one-day-a-week benefit for employees has really become an everyday thing．"可知dress-down自20世紀90年代以來成為一種日常現(xiàn)象；故選C．
31．B．推理判斷題．通讀最后一段可知休閑服有以下優(yōu)點為雇員省錢，提高雇員的工作熱情，使雇主高興等三條，故選B．

點評 考察學生的細節(jié)理解和推理判斷能力，做細節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷．

15．Have you wondered why different animals or pests have their particular colours？Colours in them seem to be used mainly to protect themselves．
Birds，especially seagulls are very fond of locusts （蝗蟲），but birds can't easily catch locusts because locusts change their colours together with the change of the colour of crops．When crops are green，locusts look green．But when crops are ripe，locusts take on exactly the same brown colour as crops have．Some other pests with different colours from plants are usually easily found and eaten by their enemies．So they have to hide themselves in terror for lives and appear only at night．
If you study the animal life in any part of the world，you will find the main use of colouring is to protect them．Bears，wolves and other beasts move quietly through forests．They are usually invisible（can't be seen） to the eyes of hunters，because they have the colour much like the bark（樹皮）of trees．
An even more strange act remains to be noticed．A kind of fish living in seas can send out a kind of very black liquid when it faces danger．While the liquid is over，its enemies cannot find it，and it quickly swims away．Thus，it has existed up to now though it is not powerful at all．
25．This passage mainly talks aboutD．
A．the change of colour in locusts
B．a(chǎn)nimals or pests can dye（染色）themselves different colours
C．how a certain sea fish protects itself
D．the protective colour of animals and pests
26．Locusts are pests but they aren't easily wiped out by their enemies becauseA．
A．they change colors with the crops              
B．they are dangerous to their enemies
C．they fly very fast                           
D．they are powerful enough
27．The pests that have different colours from plants usually appear at night becauseA．
A．their enemies can easily find them and eat them
B．they have the habit of coming out in darkness
C．it's easy for them to destroy plants in darkness
D．birds take their rests when night comes
28．A certain fish living in seas has lived through millions of year becauseC．
A．it is the most powerful in the sea
B．no other fishes can swim as fast as it can
C．it can send out a kind of liquid which makes its enemies unable to find it
D．the liquid it sends out can kill its enemies．

17．Human remains of ancient settlements will be reburied and lost to science under a law that threatens researches into the history of humans in Britain，a group of leading archaeologists （考古學家） says．In a letter addressed to the justice secretary，Ken Clarke，40 archaeologists write of their"deep and widespread concern"about the issue．It centers on the law introduced by the Ministry of Justice in 2008 which requires all human remains unearthed in England and Wales to be reburied within two years，regardless of their age．The decision means scientists have too little time to study bones and other human remains of national and cultural significance．
"Your current requirement that all archaeologically unearthed human remains should be reburied，whether after a standard period of two years or further special extension，is contrary to basic principles of archaeological and scientific research and of museum practice，"they write．
    The law applies to any pieces of bone uncovered at around 400 dig sites，including the remains of 60 or so bodies found at Stonehenge in 2008 that date back to 3，000 BC．Archaeologists have been granted a temporary extension to give them more time，but eventually the bones will have to be returned to the ground．
    The arrangements may result in the waste of future discoveries at sites such as Happisburgh in Norfolk，where digging is continuing after the discovery of stone tools made by early humans 950，000 years ago．If human remains were found at Happisburgh，they would be the oldest in northern Europe and the first indication of what this species was．Under the current practice of the law those remains would have to be reburied and effectively destroyed．
    Before 2008，guidelines allowed for the proper preservation and study of bones of sufficient age and historical interest，while the Burial Act 1857 applied to more recent remains．The Ministry of Justice assured archaeologists two years ago that the law was temporary，but has so far failed to revise it．
    Mike Parker Pearson，an archaeologist at Sheffield University，said，"Archaeologists have been extremely patient because we were led to believe the ministry was sorting out this problem，but we feel that we cannot wait any longer．"
    The ministry has no guidelines on where or how remains should be reburied，or on what records should be kept．
 
24．According to the passage，scientists are unhappy with the law mainly becauseB．
A．it is only a temporary measure on the human remains
B．it is unreasonable and thus destructive to scientific research
C．it was introduced by the government without their knowledge
D．it is vague about where and how to rebury human remains
25．Which of the following statements is true according to the passage？C
A．Temporary extension of two years will guarantee scientists enough time．
B．Human remains of the oldest species were dug out at Happisburgh．
C．Human remains will have to be reburied despite the extension of time．
D．Scientists have been warned that the law can hardly be changed．
26．What can be inferred about the British law governing human remains？D
A．The Ministry of Justice did not intend to protect human remains．
B．The Burial Act 1857 only applied to remains uncovered before 1857．
C．The law on human remains hasn't changed in recent decades．
D．The Ministry of Justice has not done enough about the law．
27．Which of the following might be the best title of the passage？D
A．New discoveries should be reburied，the government demands．
B．Research time should be extended，scientists require．
C．Law on human remains needs thorough discussion，authorities say．
D．Law could bury ancient secrets for ever，archaeologists warn．

14．Alan Tong was the worst driver in town．He had an accident of some kind almost every week．
Alan lived with his mother．His mother was always worried about him．Every day she worried that police would appear to arrest him．This wasn't a foolish worry because they usually visited Alan's house about once a week to send a speeding ticket or to serve him notice to appear in court（法庭）．
Most of his accidents were caused by his carelessness．He drove through red lights．He turned left or drove at night without proper lights．He overtook other cars on hills．In short，there wasn't a traffic rule that Alan had not broken，and he had had so many accidents that it was a surprise that he was still alive．But luckily for Alan，he had never hurt anyone in his accidents or even gone to the hospital．

"Painting my car，"Alan replied．
