【正文】 的結(jié) 果，不能與表示段的時(shí)間狀語(yǔ)連用。 I have been here since 1989. 2) since +一段時(shí)間 + ago I have been here since five months ago. 3) since +從句 Great changes have taken place since you left. Considerable time has elapsed since we have been here. 4) It is +一段時(shí)間 + since從句 It is two years since I became a postgraduate student. 被動(dòng)語(yǔ)態(tài)的幾種類型 1）主語(yǔ)句中有一個(gè)賓語(yǔ)的被動(dòng)語(yǔ)態(tài)，如： He saw her in the shop yesterday. She was seen in the shop yesterday. 2) 主語(yǔ)有兩個(gè)賓語(yǔ)的被動(dòng)語(yǔ)態(tài) Li Lei gave me a chemistry book. I was given a chemistry book by Li Lei. A chemistry book was given to me by Li Lei. 3）主動(dòng)句中含賓語(yǔ)補(bǔ)足語(yǔ) 的句子的被動(dòng)語(yǔ)態(tài) 若賓語(yǔ)補(bǔ)足語(yǔ)是不帶 to 的不定式，變?yōu)楸粍?dòng)語(yǔ)態(tài)時(shí)，該不定式前要加 to。 ) 小竅門： 當(dāng)現(xiàn)在完成時(shí) +一段時(shí)間，這一結(jié)構(gòu)中，我們用下面的公式轉(zhuǎn)化，很容易就能排除非延續(xù)動(dòng)詞在完成時(shí)中的誤使。 I worked here for more than twenty years. (我現(xiàn)在已不在這里工作。 （錯(cuò)） I have received his letter for a month. （對(duì)） I haven’t received his letter for almost a month. 12. 比較 since和 for Since 用來說明動(dòng)作起始時(shí)間， for用來說明動(dòng)作延續(xù)時(shí)間長(zhǎng)度。 注意：非延續(xù)性動(dòng)詞的否定形式可以與表示延續(xù)時(shí)間的狀語(yǔ)連用。 (2) Have you ____ been to our town before? No, it’s the first time I ___ here. A. even, e B. even, have e C. ever, e D. ever, have e 答案 D. ever意為曾經(jīng)或無論何時(shí)，反意詞為 never，此兩詞常用于完成時(shí)。 This is the first time (that) I’ve heard him sing. 這是我第一次聽他唱歌。 I hope they have a nice time next week. Make sure that the windows are closed before you leave the room. 11. 用于現(xiàn)在完成時(shí)的句型 1） It is the first / second time…. that… 結(jié)構(gòu)中的從句部分，用現(xiàn)在完成時(shí)。 The train leaves at six tomorrow morning. When does the bus star? It stars in ten minutes. 2）倒裝句，表示動(dòng)作正在進(jìn)行，如： Here es the bus. = The bus is ing. There goes the bell. = The bell is ringing. 3）在時(shí)間或條件句中。 I am to play football tomorrow afternoon. (客觀安排 ) I’m going to play football tomorrow afternoon. (主觀安排 ) 7. 一般現(xiàn)在時(shí)表將來 1）下列動(dòng)詞： e, go, arrive, leave, start, begin, return的一般現(xiàn)在時(shí)表將來。 5. be going to / will 用于條件句時(shí)， be going to 表將來 will 表意愿 If you are going to make a journey, you’d better get ready for it a s soon as possible. Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror. 6. be to和 be going to be to 表示客觀安排或受人指示而做某事。 We are to discuss the report next Saturday. 4) be about to +不定式，意為馬上做某事。 The play is going to be produced next month。 a. 主語(yǔ)的意圖，即將做某事。 will 在陳述句中用于各人稱，在爭(zhēng)求意見時(shí)常用于第二人稱。 He is used to a vegetarian diet.

A. didn’t B. couldn’t C. don’t D. can’t 答案 A. 本句雖沒有明確的時(shí)間狀語(yǔ)，但從語(yǔ)意上看 出，在聽的時(shí)候沒 有聽懂這個(gè)動(dòng)作發(fā)生在過去，因此應(yīng)用過去時(shí)。 Did you want anything else? I wondered if you could help me. 2）情態(tài)動(dòng)詞 could, would. C
