參考答案
　　1.正確答案：C答案解析：像這類題考查單詞的掌握，四個(gè)詞意思不一樣，就看哪一個(gè)放在句中邏輯上、語(yǔ)法上是正確的。這里come to the conclusion是一個(gè)固定詞組，意指“得出結(jié)論”。
　　2.正確答案：A答案解析：本題考查的是虛擬語(yǔ)氣的用法，表示的是與過(guò)去相反的情況，要用過(guò)去完成時(shí)，答案為A.
　　3.正確答案：A答案解析：本題考查的是固定搭配的用法。have no choice but to do sth.表示“別無(wú)選擇只能做某事”。
　　4.正確答案：B答案解析：account for表示：是……的原因/理由。
　　5.正確答案：C答案解析：本題考查的是if引導(dǎo)的虛擬條件句，省略了if要把had提前。
　　6.正確答案：C答案解析：本題考查的是have objection to doing sth的用法。
　　7.正確答案：D答案解析：bring out：出版，生產(chǎn)；come about：發(fā)生，產(chǎn)生；get down to：開(kāi)始認(rèn)真考慮；make up for：補(bǔ)償，彌補(bǔ)。
　　8.正確答案：D答案解析：本題考查的是would rather引導(dǎo)的虛擬語(yǔ)氣的用法，是對(duì)現(xiàn)在的虛擬，所以要用一般過(guò)去時(shí)。
　　9.正確答案：D答案解析：注意本題的解題關(guān)鍵是By the end of next month，所以要用將來(lái)完成時(shí)。
　　10.正確答案：C答案解析：本題考查的是so+形容詞+a/an+名詞的用法。
　　11.正確答案：D答案解析：it在這里做形式賓語(yǔ)。句意為：一些在自己領(lǐng)域才智過(guò)人并且非常成功的人發(fā)現(xiàn)，在語(yǔ)言學(xué)習(xí)上取得成功是很困難的。
　　12.正確答案：C答案解析：空格處應(yīng)該用形容詞原形，more than 4000 miles wide：4000多英里寬。

　　15.正確答案：B答案解析：本句屬于as/though引導(dǎo)的讓步從句，將表語(yǔ)或狀語(yǔ)提前（形容詞， 副詞， 分詞， 實(shí)義動(dòng)詞提前）。
　　16.正確答案：A答案解析：介詞in后接動(dòng)名詞，所以正確答案為A.
　　17.正確答案：C答案解析：這里所要考查的是虛擬語(yǔ)氣的用法，句子中的單詞proposal后面的從句做它的同位語(yǔ)，從句中應(yīng)該使用虛擬語(yǔ)氣，形式為“（should）+動(dòng)詞原形”，再者，動(dòng)詞應(yīng)該用被動(dòng)語(yǔ)態(tài)，所以正確答案為C.
　　18.正確答案：B答案解析：本題考查的是引導(dǎo)詞的用法，這里的句子主語(yǔ)是aggression is caused by male hormones，因?yàn)橹髡Z(yǔ)過(guò)長(zhǎng)，所以后置，用形式it來(lái)替代，后面的引導(dǎo)詞就需要用that，所以答案選B.
　　19.正確答案：B答案解析：“這位演員在演這出戲之前幾乎大多數(shù)觀眾都不知道他。”“be unknown to ”不知道，陌生。選B. unknown.
