Scarf is used to taking a walk.(现在习惯于散步) 典型例题 - Your phone number again? I _ quite catch it. - Its 69568442. A. didnt B. couldnt C. dont D. cant 答案 A. 本句虽没有明

8、确的时间状语，但从语意上看 出，在听的时候没有听懂这个动作发生在过去，因此应用过去时。 4. 一般将来时 1) shall 用于第一人称，常被 will 所代替。 will 在陈述句中用于各人称，在争求意见时常用于第二人称。 Which paragraph shall I read first. Will you be at home at seven this evening? 2) be going to +不定式，表示将来。 a. 主语的意图，即将做某事。 What are you going to do tomorrow? b. 计划，安排要发生的事。 The play is goin

It stars in ten minutes. 2）倒装句，表示动作正

12、在进行，如： Here comes the bus. = The bus is coming. There goes the bell. = The bell is ringing. 3）在时间或条件句中。 When Bill comes (不是 will come), ask him to wait for me. Ill write to you as soon as I arrive there. 4）在动词 hope, take care that, make sure that 等后。 I hope they have a nice time next week. Make sure

13、 that the windows are closed before you leave the room. 11. 用于现在完成时的句型 1） It is the first / second time. that结构中的从句部分，用现在完成时。 It is the first time that I have visited the city.

14、r) seen. 这是我看过的最好的电影。 This is the first time (that) Ive heard him sing. 这是我第一次听他唱歌。 典型例题 (1) -Do you know our town at all? -No, this is the first time I _ here. A. was B. have been C. came D. am coming 答案 B. This is the first time 后面所加从句应为现在完成时，故选 B。 (2) -Have you _ been to our town before? -No, its

15、 the first time I _ here. A. even, come B. even, have come C. ever, come D. ever, have come 答案 D. ever 意为曾经或无论何时，反意词为 never，此两词常用于完成时。 This is the largest fish I have ever seen. It is / was the first time +that-clause 的句型中，从句要用完成时。注意：非延续性动词的否定形式可以与表示延续时间的状语连用。即动作不发生的状态是可以持续的。 （错）I have received his

16、letter for a month. （对）I havent received his letter for almost a month. 12. 比较 since 和 for Since 用来说明动作起始时间， for 用来说明动作延续时间长度。 I have lived here for more than twenty years. I have lived here since I was born. My aunt has worked in a clinic since 1949. Some new oilfields have been opened up since 197

17、6. I have known Xiao Li since she was a little girl. My brother has been in the Youth League for two years. I have not heard from my uncle for a long time. 注意：并非有 for 作为时间状语的句子都用现在完成时。 I worked here for more than twenty years. (我现在已不在这里工作。) I have worked here for many years. (现在我仍在这里工作。) 小窍门： 当现在完成时

18、+一段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。 1) (对) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now. 2) (错) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now. 显然，第二句不对，

19、它应改为 Harry got married six years ago. 或 Harry has been married for six years. 13. since 的四种用法 1) since +过去一个时间点 (如具体的年、月、日期、钟点、1980, last month, half past six)。 I have been here since 1989. 2) since +一段时间+ ago I have been here since five months ago. 3) since +从句 Great changes have taken place since

20、you left. Considerable time has elapsed since we have been here. 4) It is +一段时间 + since 从句 It is two years since I became a postgraduate student. 被动语态的几种类型 1）主语句中有一个宾语的被动语态，如： He saw her in the shop yesterday. She was seen in the shop yesterday. 2) 主语有两个宾语的被动语态 Li Lei gave me a chemistry book. I was

21、 given a chemistry book by Li Lei. A chemistry book was given to me by Li Lei. 3）主动句中含宾语补足语的句子的被动语态 若宾语补足语是不带 to 的不定式，变为被动语态时，该不定式前要加 “to“。此类动词为 感官动词：feel, hear, help, listen to, look at, make, observe, see, notice, watch The teacher made me go out of the classroom. I was made to go out of the class

22、room (by the teacher). We saw him play football on the playground. He was seen to play football on the playground. 若宾语补足语是带 to 的不定式，那么被动语态仍保留 to: Mother told me not to be late I was told not to be late by mother. 5）情态动词+ be +过去分词，构成被动语态。 Coal can be used to produce electricity for agriculture and in

23、dustry. 6）表示“据说“或“相信“ 的词组 ? believe, consider, declare, expect, feel , report, say, see, suppose, think, understand It is said that 据说 It is reported that 据报道 It is believed that 大家相信 It is hoped that 大家希望 It is well known that 众所周知 It is thought that 大家认为 It is suggested that 据建议 It is taken grante

24、d that 被视为当然 It has been decided that 大家决定 It must be remember that务必记住的是 It is said that she will leave for Wuhan on Tuesday. 14. 延续动词与瞬间动词 1) 用于完成时的区别 延续动词表示经验、经历； 瞬间动词表示行为的结 果，不能与表示段的时间状语连用。 He has completed the work. 他已完成了那项工作。 (表结果 ) Ive known him since then. 我从那时起就认识他了。(表经历) 2) 用于 till / until

25、 从句的差异 延续动词用于肯定句，表示“做直到“ 瞬间动词用于否定句，表示“ 到，才“ He didnt come back until ten oclock. 他到 10 点才回来。 He slept until ten oclock. 他一直睡到 10 点。 典型例题 1. You dont need to describe her. I _ her several times. A. had met B. have met C. met D. meet 答案 B. 首先本题后句强调对现在的影响，我知道她的模样，你不用描述。再次，several times 告知为反复发生的动作，因此用现在完成时。 2.-Im sorry to keep you waiting.
