33. —I’m sorry, but I don’t quite follow you. Did you say you wanted to return on September 20?

—Sorry, I______ myself clear. We want to return on October 20.

A. hadn’t made          B. wouldn’t make      C. don’t make           D. haven’t made

分析：D。對(duì)方?jīng)]聽(tīng)清楚說(shuō)話者說(shuō)的話，是由于說(shuō)話者沒(méi)有說(shuō)清楚所導(dǎo)致的結(jié)果，所以空格處應(yīng)填現(xiàn)在完成時(shí)，即用現(xiàn)在完成時(shí)表示某個(gè)動(dòng)作所造成的影響或結(jié)果。

34. When you are home, give a call to let me know you ______ safely.

A. are arriving           B. have arrived          C. had arrived           D. will arrive

分析：B。根據(jù)句子本身已有的時(shí)態(tài)可知，過(guò)去完成時(shí)had arrived不能選；再根據(jù)常識(shí)，說(shuō)話人應(yīng)該是叫對(duì)方“已經(jīng)”到家后才打電話報(bào)平安，故選現(xiàn)在完成時(shí)。

35. Up to now, the program ______ thousands of children who would otherwise have died.

A. would save           B. saves                    C. had saved             D. has saved

分析：D。短語(yǔ)up to now的意思是“到現(xiàn)在為止”，指從過(guò)去某時(shí)開(kāi)始持續(xù)到現(xiàn)在的一段時(shí)間，通常與現(xiàn)在完成時(shí)連用。如：Her life has run smoothly up to now. 她的生活到目前仍一帆風(fēng)順。 Up to now, the work has been easy. 到現(xiàn)在為止這工作還算容易。

36. For many years, people ______ electric cars. However, making them has been more difficult than predicted.

A. had dreamed of     B. have dreamed of    C. dreamed of           D. dream of

分析：B。根據(jù)句意和句中的時(shí)態(tài)has been可知，空格處不可能填過(guò)去時(shí)態(tài)，故可排除A和C；比較B和D，B為現(xiàn)在完成時(shí)，與句中的for many years（多年來(lái)）相吻合，故選B。

37. 一When shall we restart our business?

一Not until we ______ our plan.

A. will finish             B. are finishing          C. are to finish          D. have finished

分析：D。由于until引導(dǎo)的是時(shí)間狀語(yǔ)從句，所以不能直接使用將來(lái)時(shí)態(tài)，由此可排除A；再根據(jù)句意和常識(shí)可知，人們通常是先制定計(jì)劃，然后付諸實(shí)施，故空格處填現(xiàn)在完成時(shí)比較符合句子語(yǔ)境。

38. —We’ve spent too much money recently.

—Well, it isn’t surprising. Our friends and relatives ______ around all the time.

A. are coming           B. had come              C. were coming         D. have been coming

分析：D。現(xiàn)在完成時(shí)的基本用法是從過(guò)去一直持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)。根據(jù)句意可知，正是因?yàn)樽罱�一直有朋友和親戚來(lái)訪，所以導(dǎo)致花錢較多。

39. —Why do you want to work for our company?

—This is the job that I ______ for.

A. looked                  B. am to look            C. had looked            D. have been looking

分析：D。用現(xiàn)在完成時(shí)表示最近一直在做的事情，以強(qiáng)調(diào)求職者對(duì)此工作的重視和珍惜。又如：

We have been entertaining each other in your absence. 你不在時(shí)我們彼此款待。

Snails have been eating our lettuces. 蝸牛一直在吃我們的萵苣。
