2、情況的假設(shè),因而應(yīng)該選(Bwould have lost為正確答案。2. Had Paul received six more votes in the last election, he our chairman now.A. must have beenB. would have beenC. wereD. would be解析:這道題目是一個(gè)混合虛擬語氣的句子。條件句省略了if,把助詞had提前到主語前面,表示對過去情況的假設(shè),而主句中now表明了對現(xiàn)在情況的假設(shè),所以應(yīng)選would(should, could, might+動(dòng)詞原形這種表達(dá)形式。四個(gè)選項(xiàng)中只有(D是正確表達(dá)形式,故為正

3、確答案。3.

4、spite ofB. But forC. Because ofD.

Look at the terrible situation I am in! If only I your adviceA. followB. would followC.

5、 had followedD. have followed解析:題目中的第一句話表示的是現(xiàn)在真實(shí)的情況,而第二句話中所要表達(dá)的是應(yīng)該做但事實(shí)上沒有做的事,這種情況導(dǎo)致第一句話中真實(shí)情況的發(fā)生,故If only條件句假設(shè)的是過去一種情況,因此應(yīng)該用had +過去分詞,所以正確答案是(C。6.

6、析:句意為:“要是有一聲巨響,這些動(dòng)物會(huì)受到驚嚇,這是有現(xiàn)實(shí)可能性的?！眘hould there be表示虛擬條件句中將來時(shí)間的謂語形式, if省略,所以should與there倒裝。因此B. should there be 就是本題答案。7、When Edison died, it was proposed that the American people all power in their homes, streets, and factories for several minutes in honour of this great man.A. turn offB. turned o

7、ffC. would turn offD. had turned off解析:propose是欲望動(dòng)詞,后接的賓語從句或主語從句中謂語要用虛擬語氣:should+動(dòng)詞原形或直接用動(dòng)詞原形。選擇(A. turn off8、I apologize if I you, but I assure you it was unintentional.A. offendB. had offendedC. should have offendedD. might have offended解析:B. had offended 。本題測試交錯(cuò)時(shí)間的虛擬條件句。was 暗示,事情發(fā)生在過去,所以虛擬條件句中的謂語

9、ight away.A. had to be printedB. should have been printedC. must be printedD. should be printed解析:it是形式賓語,urgent是賓語補(bǔ)足語,that引導(dǎo)的從句是真正的賓語從句,該從句的內(nèi)容被認(rèn)為是urgent(急迫的,這樣從句的謂語動(dòng)詞要求用虛擬語氣形式,即should(可以省略+動(dòng)詞原形。因此,本題正確答案是(D。11、Jean Wagners most enduring contribution to the study of Afro-American poetry is his insis

11、 I _ fully occupied the whole of last week.A. wereB. had beenC. have beenD. was解析:(D本道題目的前半句話是對過去情況的一種假設(shè),但事實(shí)上并沒有發(fā)生,而事實(shí)上沒有發(fā)生的真實(shí)原因是句子的后半部分由but引導(dǎo)的轉(zhuǎn)折句所表述的真實(shí)。因而but所引導(dǎo)的句子中應(yīng)該用表示志過去事實(shí)相符合的表陳述的時(shí)態(tài),即一般過去時(shí)。13.

14、. circlesC. is circlingD. be circling解析:if引導(dǎo)的從句要求用虛擬語氣,表示同時(shí)或?qū)淼那闆r,動(dòng)詞要用過去式(be動(dòng)詞用were或would(could 等+動(dòng)詞原形,本句話中指的是當(dāng)時(shí)的情況,所以要用過去式,故(A是正確答案。16. If the Watergate Incident Nixon would not have resigned from the presidency.A. did not occurB. had not occurredC. was not occurringD. be circling解析:(Bhad not occur

15、red表示對過去的虛擬,條件句中要用過去完成式,主句中要用should(would, could, might+動(dòng)詞原形的過去分詞。17.

16、edings .A. if he didnt get a flat tireB. if the flat tire hadnt happenedC. had he not had a flat tireD. had the tire not flattened itself解析:表示對過去情況的假設(shè),主句動(dòng)詞形式為would(should, could, might+have+過去分詞,條件句為過去完成式,if可以省略,但要把had提前主語前面。(B,(D的表達(dá)不符合英語表達(dá)習(xí)慣,所以(C是正確答案。19.

21、adC. hadnt hadD. hadnt have解析:(Cwho引導(dǎo)的定語從句中的現(xiàn)在完成時(shí)表示動(dòng)作業(yè)已發(fā)生,所以主句中表示的虛擬是針對已經(jīng)發(fā)生了的行為,所以應(yīng)該用過去完成式表示對過去的虛擬。27.

22、短語without,表示潛在的一種假設(shè),而主句中的情況也早已經(jīng)發(fā)生,所以是對過去情況的一種假設(shè),因此用would not have been achieved這一形式。28.
