【例2】He was hoping to go abroad but his parents __________ that they won’t support him unless he can borrow money from the bank.

A. were deciding                                 B. have decided

C. decided                                          D. will decide

分析：B。因賓語從句中的時態(tài)是一般將來時，主句中的謂語動詞不可能是過去時態(tài)，排除選項A和D; 由語境判斷，不是“將要決定”，而是“現(xiàn)在已經(jīng)決定”，所以排除D，而選B。

【例3】 —How can I apply for an online course?

—Just fill out this form and we __________ what we can do four you.

A. see                                                B. are seeing

C. have seen                                       D. will see

分析：D。表示將要發(fā)生的情況，自然是用一般將來時。

【例4】If their marketing plans succeed, they _________ their sales by 20 percent.

A. will increase                                   B. have been increasing

C. have increased                                D. would be increasing

分析：A。由于if條件從句用的是一般現(xiàn)在時，所以其相應(yīng)的主句宜用一般將來時。

【例5】 Population experts predict that most people _________ in cities in the near future.

A. live                                                B. would live

C. will live                                          D. have lived

分析：C。根據(jù)句中的in the near future可知要用一般將來時。

【例6】When I talked with my grandma on the phone, she sounded weak, but by the time we ________ up, her voice had been full of life.

A. were hanging                                  B. had hung

C. hung                                              D. would hang      

分析：C。從邏輯上說，當(dāng)我在電話里和奶奶聊天時，她的聲音聽起來很虛弱；但到我們要掛電話時，她的聲音又充滿朝氣。從邏輯上說，應(yīng)該是“奶奶的聲音又充滿朝氣”在先，“我們掛斷電話”在后，如果是反過來的話，那說話者就無法聽知道“奶奶的聲音又充滿朝氣”之回事了。所以“掛斷電話”應(yīng)用一般過去時。另外，由于by the time后接的定語從句通常要用一般現(xiàn)在時代替一般將來時，用一般過去時代替過去將來時，所以選項D不能選。

【例7】—Ann is in hospital.

—Oh, really? I ________ know. I ________ go and visit her.

A. didn’t; am going to                          B. don’t; would

C. don’t; will                                       D. didn’t; will

分析：D。根據(jù)句意，在此之前說話人不知道安住院了，因此第一空用一般過去時；說話人打算去看她，這個動作還沒發(fā)生，因此第二空用一般將來時。注意be going to與will表示將來的區(qū)別：表示臨時的決定，要用be going to，不用 will(www.hz123456.com)。

【例8】I’ll go to the library as soon as I finish what I ______.

A. was doing                                       B. am doing        

C. have done                                        D. had been doing

分析：B。句意是：我一完成我做的工作就去圖書館。由于“去圖書館”用的是一般將來時，說明要完成的工作是“現(xiàn)在”正在做的事情，故用現(xiàn)在進(jìn)行時。又如：

He is studying architecture. 他在學(xué)習(xí)建筑。

The ambulance is carrying wounded people to the nearest hospital. 救護(hù)車正在把受傷的人送到最近的醫(yī)院。
