【解析】

試題分析：本文談?wù)摰氖顷P(guān)于空氣污染。如果每個(gè)人都意識(shí)到環(huán)境的重要性并且做一些事情阻止污染，這個(gè)問題將被解決。

1.1】句意：因?yàn)榭諝獾奈廴�，air pollution 是名詞，所以because 后面要加of，可知此處填of。

2.2】此處應(yīng)用副詞修飾動(dòng)詞，main是形容詞，故填mainly。句意：空氣的污染主要是由下面的理由引起的。

3.3】此處是一個(gè)非限制性定語(yǔ)從句，cars and buses 是先行詞，指物，定語(yǔ)從句缺少主語(yǔ)，缺少引導(dǎo)詞，又因that不能引導(dǎo)非限制性定語(yǔ)從句,，故填which。

4.4】汽車放出有毒的氣體，gases 是名詞，所以用形容詞修飾，poison是名詞，其形容詞是poisonous，故填poisonous。

5.5】上一句說道：百分之35的空氣污染是由工廠引起的。所以下面說：另一個(gè)因素是吸煙�？芍颂幪預(yù)nother，注意大寫開頭。

6.6】上句提到的是吸煙，故此空填Smoking。句意：吸煙有害于別人的健康。

7.7】此處考查替代，health 是不可數(shù)名詞，of the smokers 是后置定語(yǔ)，所以用that替代health ，故填that。句意：吸煙即有害于別人的健康也有害于自己的健康。

8.8】take the place of 頂替、代替，故填the。句意：新染料能被用來代替汽。

9.9】句意：如果每個(gè)人都意識(shí)到環(huán)境的重要性。the放在名詞前面，“環(huán)境的重要性”， important是形容詞，應(yīng)用它的名詞importance，故填 importance。

10.10】problem 和solve之間是被動(dòng)關(guān)系，根據(jù)前面句意“如果每個(gè)人都意識(shí)到環(huán)境的重要性并且做一些事情阻止污染”可知此處表示將來，因此這里應(yīng)用一般將來時(shí)態(tài)的被動(dòng)語(yǔ)態(tài)，故填will be solved。

考點(diǎn)：考查語(yǔ)法填空

Protagoras was among the great teachers of ancient Athens. He taught many subjects, including the laws of argument(辯論) and the right use of language. It is said that he was the first teacher to accept money for his services.

A student, Evalthus, heard of this famous teacher and asked him to give him lessons. However, Evalthus didn’t want to pay for his lessons at once, and after some discussion it was finally agreed between them that Evalthus should pay only if he won his first case in the court. For if he won, it would prove that he had been taught well.

The lessons began and Evalthus proved himself to be a good student. But he refused to pay Protagoras anything at the end of his studies.

Protagoras therefore took Evalthus to the court and told the judges that he wanted his money. He explained that he must be paid whether he won or lost the case. “Whatever you decide,” he declared(宣稱)to the judges, “ I must be paid. For if you decide in my fovor , then I win the case, and so I must be paid . But If you decide against me, then Evalthus has won his first case in the court; according to our agreement, he must pay his lessons. Therefore I shall get my money whatever happens.”

The Athenian judges found no fault in it, so they asked Evalthus to reply.

“No, it’s quite clear,” said Evalthus, “ that I need not pay. If the judged decide in my favor, then I have won the case, and I need not to pay. But if Protagoras wins, then I have lost my first case. Therefore, according to our agreement, I do not have to pay. So I need not pay in any event.”

As both arguments appeared to be faultless, the judges were unable to come to a decision. They therefore ordered the two men to appear before them again one hundred years later.

1.Evalthus would pay Protagoras _______________.

A. before he started his lessons

B. after he finished his lessons

C. after the court decided against him

D. after the court proved that he was taught well

2.What do we know about Protagoras?

A. He won the judges’ favor in the end and got his money.

B. He was probably the first teacher to accept money for his lessons.

C. He didn’t teach Evalthus well because Evalthus didn’t pay.

D. He was not confident of his winning the case in the court.

3.Why did the judged ask Protagoras and Evalthus to come to the court one hundred years later?

A. They couldn’t make a decision.

B. They needed to think it over again.

C. They wanted to make fun of them.

D. They wanted more money from them.

4.What is probably the best title for the text?

A. A Smart Student---- Evalthus

B. A Great Teacher---Protagoras

C. Come Here One Hundred Years Later

D. A Fight Between Teacher and Student
