动词的时态 --- 基本概念 5. 现在进行时和过去进行时 基本概念: 指目前(一点或一段时间) / 过去(一点或一段时间)正在发生的动作. 例句 1. I don’t really work here. I ____ until the new secretary _______. A. just help out; comes B. have just helped out; will come C. am just helping out; comes D. will just help out; has come (正确选项 C, 指目前一段时间正在发生的动作, until 引导的是时间状语从句,动词需用一般现在时.) 2. --- When shall we leave? --- As soon as I ______ what I _______. A. will finish; do B. have finished, am doing C. finish, will do D. finish, do (正确选项B, as soon as 从句前省略了主句, 时间状语从句中动词强调将来的结果用现在完成时; what I am dong 指目前正在做的事.) 3. At that time he _____ in the library. A. worked B. had worked C. was working D. would work (正确选项C, was working 指 at that time 正在发生的行为.) 4. The students ____ busily when Miss Brown went to get a book she____in the office. A. were working; had left B. worked; left C. had worked; left D. were working; would leave (正确选项A, 句中went 是说话人给定的时间, work 和leave发生的时间都要看它们与went 的时间关系, work 与went动作同时发生, 强调正在做,用过去进行时; leave 在went之前发生, 应用过去完成时.) 5. --- Hey, look where you are going! --- Oh, I’m terribly sorry. _______. A. I’m not noticing. B. I wasn’t noticing. C. I haven’t noticed. D. I don’t notice. E. I didn’t notice. F. I won’t notice. (正确选项B, 对话的后者显然是在解释刚才不小心冒犯对方时正在做的事情.) 6. 一般过去时和过去进行时 比较下列句子： * I wrote a letter yesterday. （信写完了） * I was writing a letter yesterday. （一直在写信，但不一定写完了） * I was writing a letter when he came in. (他进来时，我正在写) 从以上例句可以看出，一般过去时常常用来表示过去的一个有结果的动作，而过去进行时1）强调动作在某一时刻正在发生2）动作在过去一段时间内一直在发生，无论哪一种情况都不强调动作的结果。再如： *He ______ a book about China last year, but I don’t know if he ______ it. wrote; has finished B. was writing; has finished C. was writing; had finished D. wrote; will finish 正确选项为B. 从I don’t know if he has finished it. 推断，他去年正在写。 * Tom ________ into the house when no one ___________. A. slipped; was noticing B. had slipped; noticed C. slipped; had noticed D. was slipping; noticed 正确选项为A. slip和notice 为同时发生的动作，因此B、C为错误选项，slipped指过去有结果的动作（他溜进去了），when no one was noticing 指他溜进去的一刹那发生的情况（没有人注意）。 * As she ________ the newspaper, Granny _________ asleep. A. read; was falling B. was reading; fell was reading; was falling D. read; fell 正确选项为B(道理同上)。 * The last time I _________ Jane she __________ cotton in the fields. A. had seen; was picking B. saw; picked C. had seen; picked D. saw; was picking 正确选项为D(道理同上)。 7. 过去完成时 基本概念: A) 表过去某一时间以前有结果的行为 * She said she had seen the film. 这里需要注意的是，had seen 一定是发生在said之前的行为，而不是之后。 再如： * The old man _____ two days after he had been sent to hospital. A. died B. would die C. had died D. has died 正确选项为A, 因为died是发生在had been sent to hospital之后而不是之前的行为；died 是站在现在时间角度看过去，是强调过去发生了的事情，而不是强调现在如何，因此D错，B错（过去将来时是站在过去的时间角度看过去的将来）。 * Old McDonald gave up smoking for a while, but soon ______ to his old ways. A. returned B. returns C. was returning D. had returned 正确选项为A(道理同上)。 B) 表延续到过去某一时间的行为 * She said she had been a doctor for 20 years. C) 表过去某一时间以前未曾实现的愿望或打算 * I _____ my son _____ a doctor, but he wasn’t good enough at science. A. hoped; would become B. had hoped; would become C. had hoped; will become D. hope; will become 正确选项为B。 * I _____ to take a good holiday this year, but I wasn’t able to get away. A. hope B. have hoped C. had hoped D. hoped 正确选项为C。 8. 过去将来时 基本概念: 表过去某一时间之后将要发生的行为（过去的将来）。 * We were all surprised when he made it clear that he _____ office soon. A. leaves B. would leave C. left D. had left * She said she ___(leave) the next morning. 答案可以是：A. would leave B. was leaving C. was going to leave 由此可以看出, 我们在一般将来时中讨论的将来时的多种形式均可灵活地运用于过去将来时中。 9. 将来完成时 基本概念: 在讨论了现在完成时和过去完成时之后，我们应该认识到：完成时的概念其实就是两条1）表结果 2）表延续 ，站在现在时间角度看，就是现在完成时；时间移到过去就是过去完成是；时间移至将来就是将来完成时，因此，将来完成时 A) 表到将来某一时间前要完成的行为 * By the end of 2000 they will have built the factory. * We will have finished the work before she arrives tonight. B) 表延续到将来某一时间的行为 * I will have been a teacher for 20 years by the end of next year. 动词的被动语态 以上我们讨论了动词主动语态的各种时态，与主动语态一样，被动语态也有相同的各种时态。因此，我们只要关注被动语态的某些特殊用法就可以了。 被动语态的某些特殊用法 A. 有些及物动词有时形式上为主动, 表达主语的特性或特征 * The kind of cloth washes well. * The book sells / writes well. * Your hands feel cold. |
