12．China always plays ____ active part in fighting against _____natural disasters．（　�。�
A．/； theB．an； theC．an；/D．/；/

分析 中國(guó)總是在抗擊自然災(zāi)害面前起著積極作用．

解答 答案：C，考查冠詞的用法，第一個(gè)空考查固定短語(yǔ)中的冠詞，play an active part表示"起著積極作用"；第二個(gè)空"自然災(zāi)害"是泛指，其前不用冠詞，故答案為C．

點(diǎn)評(píng) 考查冠詞的用法，注意區(qū)分句中是泛指還是特指，泛指則用不定冠詞a/an，特指則用定冠詞the，還應(yīng)注意某些冠詞的固定搭配．

5．A year ago，I paid no attention to English idioms，though my teacher emphasized （強(qiáng)調(diào)） the importance again and again．But soon，the importance of English idioms was shown in an  amusing experience
One day，I happened to meet an Englishman on the road，and soon we began to talk．As I was talking about how I was studying English，the foreigner seemed to be surprised．Gently shaking his head，shrugging his shoulders，he said，"You don't say!""You don't say!"I was puzzled．I thought，perhaps this is not a proper topic．"Well，I'd better change the topic．"So I said to him，"Well，shall we talk about the Great Wall？By the way，have you ever been there？""Certainly，everyone back home will laugh at me if I leave China without seeing it．It was wonderful．"He was deep in thought when I began to talk like a tourist guide．"The Great Wall is one of the wonders in the world．We are very proud of it．"Soon I was stopped again by his words："You don't say!"I couldn't help asking，"Why do you ask me not to talk about it？""Well，I didn't ask you to do so，"he answered，greatly surprised．I said，"Didn't you say‘you don't say'？"Hearing this，the Englishman laughed to tears．He began to explain，‘You don't say．'actually means‘really'!It is an expression of surprise．Perhaps you don't pay attention to English idioms．"Only then did I know how foolish I had been．Since then I have been more careful with idiomatic expressions．Remember：what the English teachers said is always right to us students．

56．At first，on hearing"You don't say"，I thought the foreigner meantC．
A．I had talked too much 
B．I had to stop talking
C．He was not interested in the topic
D．He was only interested in the Great Wall
57．The underlined word in the first paragraph probably meansA．
A．interesting   B．important  
C．terrible      D．unlucky
58．Which of the following is true according to the passage？D
A．The Englishman wanted me to act as his guide．
B．The Englishman left China without seeing the Great Wall．
C．The Englishman wanted to see the Great Wall after I talked about it．
D．The Englishman visited the Great Wall and thought it worth visiting．

A．I felt very foolish

C．I became more careful in everything
D．I thought the Englishman had made me a fool．

4．Long after the 1998World Cup was won，disappointed fans were still cursing the disputed refereeing（裁判）decisions that denied victory to their team．A researcher was appointed to study the performance of some top referees．
The researcher organized an experimental tournament（錦標(biāo)賽）involving four youth teams．Each match lasted an hour，divided into three periods of 20minutes during which different referees were in charge．
Observers noted down the referees'errors，of which there were 61over the tournament．Converted to a standard match of 90minutes，each referee made almost 23mistakes，a remarkably high number．
The researcher then studied the videotapes to analyze the matches in detail．Surprisingly，he found that errors were more likely when the referees were close to the incident．When the officials got it right，they were，on average，17meters away from the action．The average distance in the case of errors was 12meters．The research shows the optimum（最佳的）distance is about 20meters．
There also seemed to be an optimum speed．Correct decisions came when the referees were moving at a speed of about 2meters per second．The average speed for errors was 4meters per second．
If FIFA，football's international ruling body，wants to improve the standard of refereeing at the next World Cup，it should encourage referees to keep their eyes on the action from a distance，rather than rushing to keep up with the ball，the researcher argues．
He also says that FIFA's insistence that referees should retire at age 45may be misguided．If keeping up with the action is not so important，their physical condition is less critical．

51．The experiment conducted by the researcher was meant toB．
A．review the decisions of referees at the 1998World Cup
B．a(chǎn)nalyze the causes of errors made by football referees
C．set a standard for football refereeing
D．reexamine the rules for football refereeing
52．The number of refereeing errors in the experimental matches wasC．
A．slightly above average
B．higher than in the 1998World Cup
C．quite unexpected
D．a(chǎn)s high as in a standard match
53．The findings of the experiment show thatA．
A．errors are more likely when a referee keeps close to the ball
B．the farther the referee is from the incident，the fewer the errors
C．the more slowly the referee runs，the more likely will errors occur
D．errors are less likely when a referee stays in one spot
54．The word"officials"（Line 3，Para.4）most probably refers toC．
A．the researchers involved in the experiment
B．the inspectors of the football tournament
C．the referees of the football tournament
D．the observers at the site of the experiment
55．What is one of the possible conclusions of the experiment？B
A．The ideal retirement age for an experienced football referee is 45．
B．Age should not be the chief consideration in choosing a football referee．
C．A football referee should be as young and energetic as possible．
D．An experienced football referee can do well even when in poor physical condition．
