—Why did you leave without a word of warning to John?

—But what _____ otherwise? He never listens to me.

A.could I have done                       B.would I do

C.must I have done                        D.should I do

 

【答案】

A

【解析】

試題分析:句意:--為什么你沒有留下一句話就離開了?--但是要不我能做什么?他也不聽我的。根據(jù)第一句可知這里他的離開發(fā)生在過去,故用情態(tài)動詞+have done,所以排除BD;must have done不能用在疑問句中,故選A。

考點:考查情態(tài)動詞的用法。

點評:本題難度適中。情態(tài)動詞的完成式是高中階段的重難點之一,需要考生熟記它們的用法,在各類考試中經(jīng)常出現(xiàn),它主要用于表示對過去情況進(jìn)行推測或責(zé)備等。

即學(xué)即練:  --- There were already five people in the car but they managed to take me as well.

--- It ___ a comfortable journey.

A. can’t be     B. shouldn’t be   C. mustn’t have been  D. couldn’t have been

解析:D。They were already five people in the car, but they managed to take me as well.一句中的時態(tài),應(yīng)該是對過去情況的推測判斷,因為車上已經(jīng)有5位人了,在帶上我一個,可以斷定這一定是一次不舒適的旅行。所以,本句表達(dá)的是對過去否定的推測判斷,應(yīng)該用can’t/ could have done來表達(dá)。故答案選D。

At lunch time one day, a week before her mother’s birthday, Sally decided to have a quick sandwich and a cup of coffee instead of her usual 1 in the college hall, and then go 2 near her college to try to find her mother a nice present. When she had been looking for half an hour, she 3 across a shop that was selling umbrellas cheap, and 4 that one of those would solve her problem, since her mother had lost hers the month before.

Now which 5 shall I chooseshe thought.Well, I think a black one would be the most useful really. You can carry that when you are wearing 6 of any color, can’t you?So having made up her 7 , she bought a lovely black umbrella and took it back to the college with her 8 her classes had finished.

On her way back home in the train that evening she felt hungry because she had had such a small lunch, so she went 9 to the buffet car(餐車) for another sandwich and cup of coffee. She had 10 the black umbrella above her seat in the compartment, but when she got back, it was 11 ! When she had left the compartment, there had been no other passengers in it, but now there were three.

Sally burst into 12 when she saw that the umbrella was no longer there. The other passengers felt very sorry for her and asked what the 13 was. When she explained that the black umbrella she had bought 14 her mother had disappeared, and that she had to get out at the next 15 , the three other passengers asked her for her mother’s 16 , in order to be able to send the umbrella on to her in case someone had 17 it by mistake and not on 18, and brought it back after Sally had got out of the train.

The next week, Sally heard 19 her mother. Her letter said,Thank you very much for your lovely presents, but why did you send me 20 black umbrellas?

More and more teenage addicts in Korea are refusing to leave their bedrooms and some young adults are playing fantasy games online until they literally drop dead. "He didn't adapt very easily into high school," said Chu Dong-jiu, whose son, Jae--yun, 17, cruises football websites 12 to 14 hours a day. "That was why he dropped out. Now he spends all the time he is not eating on the computer. He hasn't been out of the house for eight months."
Eighty percent of South Koreans have broadband internet, the highest rate in the world. In Britain the figure is less than a third. This is partly the result of its intense, science-based schooling.  But according to Dr. Kim Hyun-soo, chairman of the Association of Internet Addiction Psychiatrists, an "education frenzy (狂怒)" has undermined children's self-confidence and forced them to seek escape elsewhere.
Children, many tutored beyond school, enjoy little free time outside home, driving them into the solitary solace(安慰) of the computer, he said. “What children do on the Internet reflects what they want in reality,” he said. “The dreams they pursue are the dreams they would pursue in ordinary life.”
The most common obsession(迷住,困擾) is with online games in which players become fantasy figures in landscapes pitted with foes and obstacles. One 28-year-old young man collapsed and died last year after playing a game non-stop for 50 hours in an Internet cafe. Doctors said he died from exhaustion and dehydration (脫水). Studies show five percent of "gamers” are seriously addicted, with a further 15 ~ 20 percent betraying signs of an unhealthy obsession. Gamers make up 90 percent of Dr. Kim's patients, often referred to him by mental hospitals to which parents had taken their children. The other l0 percent are guilty of freakish (異想天開的)and anti-social behaviour on websites. "These people are very frustrated inside and full of anger," he said.
The government has stepped in, banning children from Internet cafes after l0 p. m. , and sending teams of psychologists to visit them.
67. This passage mainly wants to tell us that________
A. Internet cafes seriously do great harm to children's life
B. lots of students in Korea escape into Internet fantasy
C. why more and more children in Korea like Internet cafes
D. the government should take immediate actions against Internet cafes
68. Why did Jae-yun drop out of the school?
A. Because his family was too poor.    B. Because he wanted to find a job earlier.
C. Because he liked searching football websites greatly.
D. Because he liked playing all kinds of computer games, especial]y football games.
69. According to the passage, we can infer that________.
A. most of Dr. Kim's patients are game lovers
B. garners make up l0 percent of Dr. Kim's patients
C. the government in Korea hasn't taken any action to control Internet cafes so far
D. more and more teenage addicts in Korea are refusing to leave their bedrooms
