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。對方沒聽清楚說話者說的話，是由于說話者沒有說清楚所導致的結果，所以空格處應填現在完成時，即用現在完成時表示某個動作所造成的影響或結果。

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。根據句子本身已有的時態可知，過去完成時had arrived不能選；再根據常識，說話人應該是叫對方“已經”到家后才打電話報平安，故選現在完成時。

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up to now的意思是“到現在為止”，指從過去某時開始持續到現在的一段時間，通常與現在完成時連用。如：Her life has run smoothly up to now. 她的生活到目前仍一帆風順。 Up to now, the work has been easy. 到現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。根據句意和句中的時態has been可知，空格處不可能填過去時態，故可排除A和C；比較B和D，B為現在完成時，與句中的for many years（多年來）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引導的是時間狀語從句，所以不能直接使用將來時態，由此可排除A；再根據句意和常識可知，人們通常是先制定計劃，然后付諸實施，故空格處填現在完成時比較符合句子語境。

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。現在完成時的基本用法是從過去一直持續到現在的動作或狀態。根據句意可知，正是因為最近一直有朋友和親戚來訪，所以導致花錢較多。

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。用現在完成時表示最近一直在做的事情，以強調求職者對此工作的重視和珍惜。又如：

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

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