9．-Is there any chance of my borrowing your ipad？
-For how long？（　�。�----____the end of this week．
A．SinceB．UntilC．FromD．By

分析 --我可以借你的ipad嗎？
--多久？
--直到本周結(jié)束．

解答 答案是B．本題主要考查表示時間的介詞辨析．since自從（過去某一時間起）；until在肯定句中表示"動作延續(xù)到…結(jié)束"；from自從（某一時間）；by 表示"到…時候?yàn)橹梗▌幼饕呀?jīng)發(fā)生）"；根據(jù)語境判斷，how long指段時間，指借用的狀態(tài)持續(xù)多久；用until the end of the week表示"借用的狀態(tài)持續(xù)到周末"，所以答案選擇B．

點(diǎn)評 介詞辨析要在掌握各介詞的基本用法和固定搭配的基礎(chǔ)上結(jié)合語境做出符合邏輯、常理的推測．

19．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 a sports shirt-to the office．He hardly ever wears a necktie．"I am 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 and Company，85percent of employers said that they believe that casual dress improves employee morale（心境，士氣）．Only 4percent of employers said that casual dress has a negative influence 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．"

C．he wanted his clothes to look neat all the time

17．Three visitors traveling on a bus began a conversation about the world's greatest wonders．
"In my opinion，"the first visitor said，"the Egyptian pyramids are the world's greatest wonder．Although they were built thousands of years ago，they are still standing．And remember：the people who built them had only simple tools．They did not have the kind of machinery that builders and engineers have today．"
"I agree that the pyramids in Egypt are wonderful，"the second visitor said，"but I do not think they are the greatest wonder．I believe computers are more wonderful than the pyramids．They have taken people to the moon and brought them back safely．In seconds，they carry out mathematical calculations that would take a person a hundred years to do．"
