1、 Jean Wagner’s most enduring contribution to the study of Afro-American poetry is his insistence that it in a religious, as well as worldly, frame of reference.

　　A. is to be analyzed B. has been analyzed

　　C. be analyzed D. should have been analyzed

　　解析：(C)在表示要求、愿望、建議、請(qǐng)求、命令等含義的名詞同位語(yǔ)從句中，從句謂語(yǔ)動(dòng)詞要用虛擬語(yǔ)氣形式，即should(可以省略)+動(dòng)詞原形。

　　2、 I would have gone to visit him in the hospital had it been at all possible, but I ______ fully occupied the whole of last week.

　　A. were B. had been C. have been D. was

　　解析：(D)本道題目的前半句話是對(duì)過(guò)去情況的一種假設(shè)，但事實(shí)上并沒(méi)有發(fā)生，而事實(shí)上沒(méi)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(guò)去事實(shí)相符合的表陳述的時(shí)態(tài)，即一般過(guò)去時(shí)。

　　3. I apologize if I you, but I assure you it was unintentional.

　　A. offend B. had offended C. should have offended D. might have offended

　　解析：(B)此題要求在if從句中選擇適當(dāng)?shù)膭?dòng)詞形式，以主句中的動(dòng)詞apologize(抱歉)來(lái)看，if從句中表達(dá)的內(nèi)容應(yīng)該是過(guò)去做的事，因此可以排除(A)，因?yàn)?A)是現(xiàn)在時(shí)。(C)中should+have+過(guò)去分詞結(jié)構(gòu)表示本來(lái)應(yīng)該做卻沒(méi)有做的事，在此不合題意。(D)選項(xiàng)中的might+have+過(guò)去分詞表示對(duì)過(guò)去發(fā)生的事情很不肯定的猜測(cè)，它表達(dá)的內(nèi)容還不能成為事實(shí)，所以藉此道歉真是不知從何說(shuō)起，因此此處也不合題意。(B)had offended表示當(dāng)時(shí)已經(jīng)發(fā)生了的動(dòng)作。這是復(fù)雜條件句：apologize 是現(xiàn)在，而條件句是表示對(duì)過(guò)去假設(shè)的條件句。

　　4. If you hadn’t taken such a long time to get dressed, we’d there by now.

　　A. be B. circles C. is circling D. be circling

　　解析：該句也是一個(gè)復(fù)雜條件句(或稱作混合虛擬條件句)。條件句表示對(duì)過(guò)去情況的假設(shè)，而主句表示對(duì)現(xiàn)在情況的假設(shè)，但事實(shí)上卻與此相反，所以正確答案應(yīng)該是(A)。

　　5. The sun rises in the east and sets in the west, so it seems as if the sun ________round the earth.

　　A. were circling B. circles C. is circling D. be circling

　　解析：if引導(dǎo)的從句要求用虛擬語(yǔ)氣，表示同時(shí)或?qū)��?lái)的情況，動(dòng)詞要用過(guò)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(guò)去式，故(A)是正確答案。

　　6. If the Watergate Incident______ Nixon would not have resigned from the presidency.

　　A. did not occur B. had not occurred C. was not occurring D. be circling

　　解析：(B)had not occurred表示對(duì)過(guò)去的虛擬，條件句中要用過(guò)去完成式，主句中要用should(would, could, might)+動(dòng)詞原形的過(guò)去分詞。

　　7. I hadn’t expected James to apologize but I had hoped ______ .

　　A. him calling me B. that he would call me C. him to call me D. that he call me

　　解析：(B)had hoped是常見(jiàn)的要求其后的賓語(yǔ)從句用虛擬語(yǔ)氣的句型,虛擬語(yǔ)氣would+動(dòng)詞原形。

　　8. George would certainly have attended the proceedings ______ .

　　A. if he didn’t get a flat tire B. if the flat tire hadn’t happened

　　C. had he not had a flat tire D. had the tire not flattened itself

　　解析：表示對(duì)過(guò)去情況的假設(shè)，主句動(dòng)詞形式為would(should, could, might)+have+過(guò)去分詞，條件句為過(guò)去完成式，if可以省略，但要把had提前主語(yǔ)前面。(B)，(D)的表達(dá)不符合英語(yǔ)表達(dá)習(xí)慣，所以(C)是正確答案。

　　9. The teacher suggested that her students ______experiences with ESP.

　　A. write a composition on their B. to write composition about the

　　C. wrote some compositions of his or her D. had written any compositions for his

　　解析：(A)suggest后面的從句要用虛擬語(yǔ)氣形式，其形式為should(可以省略)+動(dòng)詞原形。

　　10. He speaks Chinese as fluently as if he ______a Chinese.

　　A. were B. had been C. is D. has been

　　解析：(A).表示與現(xiàn)在相反的虛擬。
