參考答案及解析:
1.D。can guess 這一現(xiàn)在猜測(cè)是建立在眼前所見(jiàn)情景的基礎(chǔ)上的，故用現(xiàn)在進(jìn)行時(shí)。
 2.A。expect, intend, want, wish, hope, plan 等動(dòng)詞的過(guò)去完成式可表示過(guò)去未曾實(shí)現(xiàn)的想法、愿望、打算等。
3.A。如主句用將來(lái)時(shí)，在時(shí)間、條件和讓步狀語(yǔ)從句中要用一般現(xiàn)在時(shí)表示將來(lái)。又因if 從句是take notice of...的被動(dòng)語(yǔ)態(tài)結(jié)構(gòu)，故選A。
4.B。根據(jù)主語(yǔ)與build之間的被動(dòng)關(guān)系和now， 可知要選現(xiàn)在進(jìn)行時(shí)的被動(dòng)語(yǔ)態(tài)；因工廠正在修建，花費(fèi)一年半應(yīng)指將來(lái)。
5.C。shouldn’ t have done 表示“過(guò)去本不應(yīng)……”。You did lose your temper 是You lost your temper 的強(qiáng)調(diào)形式。
6.D�，F(xiàn)在完成進(jìn)行時(shí)表示從過(guò)去某時(shí)到現(xiàn)在一直在進(jìn)行的動(dòng)作。
7.B。句意為：他們（現(xiàn)在）不愿買新衣服，因?yàn)樗麄冊(cè)跀�錢買電視。由此可見(jiàn)，攢錢是現(xiàn)階段正在進(jìn)行的動(dòng)作。
8.C。擔(dān)心是從過(guò)去某時(shí)到說(shuō)話時(shí)為止一直在進(jìn)行的動(dòng)作，用現(xiàn)在完成時(shí)；expect 是在過(guò)去某一段時(shí)間里（整個(gè)晚上）正在進(jìn)行的動(dòng)作，故用過(guò)去進(jìn)行時(shí)。
9.B。論文已完成，花費(fèi)一個(gè)月時(shí)間應(yīng)指過(guò)去；某事花費(fèi)某人多少時(shí)間用sth.takes sb.some time 結(jié)構(gòu)。
10.D。交通現(xiàn)在已經(jīng)好了，在此基礎(chǔ)上正在變得更好。
11.A。題干沒(méi)有構(gòu)成“過(guò)去的過(guò)去”，不可選B。如選C、D則表示動(dòng)作已完成，與have no idea相矛盾。過(guò)去進(jìn)行時(shí)表示過(guò)去某段時(shí)間或某一時(shí)刻正在進(jìn)行的動(dòng)作，不涉及結(jié)果，正好附合題干語(yǔ)境。
12.C。by then 是指將來(lái)的時(shí)間狀語(yǔ)，排除A。再由句意可知，meet指的是到了十點(diǎn)鐘時(shí)將正在進(jìn)行的動(dòng)作。
13.B。問(wèn)句問(wèn)的是前天回來(lái)之前去了哪兒，故用過(guò)去完成時(shí)。注意had gone表示人未回來(lái)，與第一句相矛盾。
14.D。for＋時(shí)間段表示從過(guò)去某時(shí)延續(xù)至今的動(dòng)作或狀態(tài)，用現(xiàn)在完成時(shí)；meet發(fā)生在got to know 這一過(guò)去動(dòng)作之前，用過(guò)去完成時(shí)。
15.D。用一般現(xiàn)在時(shí)表示現(xiàn)在的特征或狀態(tài)。
16.B。come, go, leave, arrive, take 等動(dòng)詞常用進(jìn)行時(shí)表砂將來(lái)。
17.D。表示過(guò)去沒(méi)有做某事應(yīng)用去時(shí)。又因句子沒(méi)有"過(guò)去正在進(jìn)行 "之意，幫排除A。
18.B。問(wèn)對(duì)方"去了哪里"，指的是從過(guò)去某時(shí)到現(xiàn)在為止的動(dòng)作，用現(xiàn)在完成時(shí)；第二個(gè)空格是與過(guò)去事實(shí)相反的虛擬語(yǔ)氣和主句，條件狀語(yǔ)從句If I hadn’ t got stuck in the heavy traffic 被省略。
19.C。在一個(gè)國(guó)際會(huì)議上被介紹顯然發(fā)生在過(guò)去。
20.B。此句為復(fù)雜特殊疑問(wèn)句結(jié)構(gòu)，即“疑問(wèn)詞＋do you think (believe, suppose, expect, imagine, say, consider, guess等）＋其它（陳述語(yǔ)序）?”。
21.D。由but 分句中的現(xiàn)在時(shí)和答語(yǔ)所提建議內(nèi)容，可知應(yīng)選現(xiàn)在完成時(shí)的被動(dòng)語(yǔ)態(tài)。22.C。 always, often, constantly, forever, all the time 等副詞與現(xiàn)在（過(guò)去）進(jìn)行時(shí)連用，表示某種反復(fù)發(fā)生的動(dòng)作，往往帶有厭惡、不滿、責(zé)備或贊揚(yáng)等意味。
23.B。這種電視產(chǎn)于上海是客觀事實(shí)，故用一般現(xiàn)在時(shí)。
24.C。C項(xiàng)是was to have joined us in our discussion 的省略形式。was／were ＋ to have done表示原來(lái)計(jì)劃、安排要做的事，而實(shí)際上并沒(méi)有做。
25.B。當(dāng)時(shí)他在聽(tīng)收音機(jī)。
26.D。表示按時(shí)刻表或日程安排要發(fā)生的事,應(yīng)用一般現(xiàn)在時(shí)。
27.D。從句用的是一般現(xiàn)在時(shí)，故主句要用將來(lái)時(shí)。將來(lái)進(jìn)行時(shí)表示在將來(lái)某一時(shí)刻或某段時(shí)間內(nèi)正在進(jìn)行的動(dòng)作。
28.A。Look at this!說(shuō)明東西已找到。緊接著說(shuō)是怎樣找到的。
29.C。根據(jù)答語(yǔ)，問(wèn)句中的meet是過(guò)去發(fā)生的動(dòng)作，可排除A、D。但不能選B，因?yàn)闆](méi)有構(gòu)成“過(guò)去的過(guò)去”。答語(yǔ)中用過(guò)去完成時(shí)的被動(dòng)語(yǔ)態(tài)表示在我到達(dá)（過(guò)去動(dòng)作）之前他已被人用車接走。
30.D�！皼](méi)聽(tīng)”發(fā)生在對(duì)方（過(guò)去）問(wèn)問(wèn)題時(shí)，故用過(guò)去進(jìn)行時(shí)。
31.A。此題選A表示現(xiàn)在的特征或狀態(tài)。prefer屬表示心理狀態(tài)的動(dòng)詞，不能用于進(jìn)時(shí)。32.B。表示在過(guò)去某一動(dòng)作之前一直在進(jìn)行，并有可能繼續(xù)下去的動(dòng)作，要用過(guò)去完成進(jìn)行時(shí)。
33.A。cook發(fā)生在didn’ t taste very good 之前，且與主語(yǔ)之間有被動(dòng)關(guān)系，故用過(guò)去完成時(shí)的被動(dòng)語(yǔ)態(tài)。
34.A。read 發(fā)生在the first time we met之時(shí), 故用過(guò)去進(jìn)行時(shí)。
35.B。動(dòng)詞wash, lock, sell, wear, write read, open, shut, clean等動(dòng)詞的主語(yǔ)是物，且又表示主語(yǔ)的特征或狀態(tài)時(shí)，要用主動(dòng)形式表示被動(dòng)意義。
36.C。play 在came in 之前已完成，而do some reading 的動(dòng)作則即將開(kāi)始。
37.C。will／shall ＋v.表示臨時(shí)的決定，而be going to 表示已決定或安排要做的事。38.B。would ／ should like ＋ to have done表示過(guò)去未曾實(shí)現(xiàn)的愿望，故“未受邀請(qǐng)”應(yīng)用一般過(guò)去時(shí)的被動(dòng)語(yǔ)態(tài)。
39.B。by 后跟將來(lái)的時(shí)間狀語(yǔ)時(shí)，主句要用將來(lái)完成時(shí)。go without 意為“在缺……的情況下對(duì)付”。
40.D。all but one 主語(yǔ)是all，且all在此指人，故謂語(yǔ)動(dòng)詞用復(fù)數(shù)；take place 屬不及物動(dòng)詞短語(yǔ)，無(wú)被動(dòng)語(yǔ)態(tài)；be about to后面不能跟具體的時(shí)間狀語(yǔ)。
41.C。由對(duì)話情景可知，“周游世界”是現(xiàn)在正在進(jìn)行的動(dòng)作，而“實(shí)現(xiàn)”是到說(shuō)話時(shí)為止已完成的動(dòng)作；come true不能用于被動(dòng)語(yǔ)態(tài)。
42.A。詢問(wèn)到說(shuō)話時(shí)為止一段時(shí)間內(nèi)某動(dòng)作是否發(fā)生，要用現(xiàn)在完成時(shí)。
43.D。hear 發(fā)生在talked這一過(guò)去動(dòng)作之前；never是含有否定意義的副詞，放在句首時(shí)，句子應(yīng)用倒裝語(yǔ)序。
44.B。be用于進(jìn)行時(shí)可表示一個(gè)暫時(shí)的特點(diǎn)或表現(xiàn)。What they are up to相當(dāng)于What they are doing。
45.D。根據(jù)目前跡象判斷將要發(fā)生的動(dòng)作用be going to；if only 意為“但愿”，其后的句子用虛擬語(yǔ)氣。
46.A。由these three years可知應(yīng)選現(xiàn)在完成進(jìn)行時(shí)，表示“寫”從過(guò)去一直延續(xù)至今，并有可能繼續(xù)下去；“寫了40 篇”用現(xiàn)在完成時(shí)，表示到現(xiàn)在為止已完成的動(dòng)作。
47.D。no sooner...than和hardly(scarcely)...when 均表示“一……就……”，且主句用過(guò)去完成時(shí)，從句用一般過(guò)去時(shí)。
48.C。賓語(yǔ)從句表示的是客觀事實(shí)。
49.C。dream是從過(guò)去某時(shí)開(kāi)始一延續(xù)到are woken up...and asked to report...這一現(xiàn)在動(dòng)作之前的動(dòng)作，故用現(xiàn)在完成進(jìn)行時(shí)。
50.A。由What’ s the matter 和don’ t fit 可知，hurt是現(xiàn)在正在進(jìn)行的動(dòng)作。
