第1題

　　When an organism is completely encapsulated and preserved, it becomes a fossil, therefore turning into evidence of things that once lived.

　　A thereby B as a result of C so D in the end

　　【正確答案】：A

　　【答案解析】Therefore 和 thereby 均為副詞，表“因此”，但 therefore 后通常跟一個 句子，而 thereby 后常接現(xiàn)在分詞作狀語。as a result of 由于(as a result 才表“因此”)，因此 A 為答案。

　　第2題

　　His heavy drinking and fond of gambling makes him a poor role model. A and fact that he gambles B and that he gambles C and he gambles which D and gambling

　　【正確答案】：D

　　【答案解析】本句考查的是平行結構的用法。(并列連詞and，but，as well as，or 等連接的應是兩個或幾個同類的結構，語法上稱為平行結構)本句中and 連接的是兩個動名詞，所以選項 D 是答案。

　　第3題

　　Depression that inflicts people who believe their lives lack content when the rush of the busy week stops referred to by a prominent psychiatrist as Sunday Neurosis.

　　A .has been referred to by a prominent psychiatrist B .has been referred to as by a prominent psychiatrist C. a prominent psychiatrist has referred to it D .it has been referred to by a prominent psychiatrist

　　【正確答案】：A

　　【答案解析】 本句是個復合句：Depression 是主語，后面是 that 引導的定語從句 that inflicts people who believe their lives lack content when the rush of the busy week stops，而其中斜體部分又是一個修飾 people 的定晤從句，之后還有一個由when 引導的時間狀語從句，因此劃線部分應是謂語動詞，因此選項A正確。

　　第4題

　　Most of the older civilizations which flourished during the fifth century B.C. are died out.

　　A they have died out B has died out C have died out D they had died out

　　【正確答案】：C

　　【答案解析】本句是個復合句：Most of the older civilizations 是主語，后面是 which 引導的定語從句 which flourished during the fifth century B.C.因此劃線 部分應是謂語動詞，根據(jù)主語，謂語應用復數(shù)形式，因此選項 C 正確。

　　第5題

　　The student asked her professor if he would have gone on the space ship he did know earlier.

　　A if he knew B if he knows C he had known D had he known

　　【正確答案】：D

　　【答案解析】本句是對過去事實的假設，條件從句的謂語應用過去完成時(had known)，而 if 條件句中如有 were，should，had，可將 if 省去，而把 were，should，had 放在句首。因此選項 D 是答案。

　　第6題

　　The professor is quite difficult pleased.

　　A to please B to be pleased C for pleasing D pleasing

　　【正確答案】：A

　　【答案解析】此句是用動詞不定式作主語：To please the professor is difficult.此 句常寫作：It is difficult to please the professor.因此答案為 A。

　　第7題

　　All don't have a free ticket must pay the admission fee.

　　A Everyone who doesn't have a free ticket B No one who doesn't have a free ticket C No one who has free tickets D Anyone who has free tickets

　　【正確答案】：A

　　【答案解析】 [分析] 代詞應用。 此句考查的是帶有定語從句的代詞作主語，要表達的是：所有沒有免票的人 都要付入會費。選項 B 是雙重否定，與要表達的意思相反：選項 c 的定語從句中 的 ticket 不應用復數(shù)，選項 D 也與要表達的意思相反，而選項 A 意為“任何一 個沒有免票的人都要付入會費”。因此 A 為答案。

　　第8題

　　In our own galaxy, the Milky Way, there are perhaps 200 billion stars, a small part of them probably have planets on which life is feasible.

　　A a small fraction in which B a small fraction of which C a small fraction which D which a fraction of

　　【正確答案】：B

　　【答案解析】 [分析] 結構應用。 英語的定語從句(不論是限定性或非限定性)中，當關系代詞作介詞賓語時，介詞前置，其中 whom 指人，which 指物：而介詞 of 表示整體中的一部分，比用 in 準確，所以 B 為答案。

　　第9題

　　When I last saw them, the police had chased the robbers down Columbus Street.

　　A were chasing B was chasing C chased D were on a chase

　　【正確答案】：A

　　【答案解析】在由 when 引導的時間狀語從句的句子中， 主句和從句的謂語動詞的動作是有 先后次序的，如狀語從句的時態(tài)是一般過去時，主句應用過去時，本句表示過去 正在做的動作所以應用過去進行時，又因主語 the police 即狀語中的 them，所 以謂語為復數(shù)，答案應為 A。

　　第 10 題

　　The trapeze artist who ran away with the clown broke up the lion tamer's heart.

　　A broke away B broke down C broke D broken down

　　【正確答案】：C

　　【答案解析】 [分析] 動詞搭配。 break up 打碎， 終止， 驅散; break away 突然離開， 放棄(習慣等); break down 毀掉，制服，中止;而本句要表達的意思是：令訓獅員非常傷心;所以應用 break one's heart，選項 C 正確。
