3、1 and unit 2 language practice1. read through the example sentences in the box with the whole class.grammar.時態(tài)復(fù)習(xí)到目前為止，我們已經(jīng)學(xué)過了英語中常用的時態(tài)，包括一般現(xiàn)在時、一般過去時、現(xiàn)在進行時、過去進行時、一般將來時和現(xiàn)在完成時。在本模塊中，我們將對這些時態(tài)的用法進行總結(jié)。各種時態(tài)中一般疑問句和否定句的構(gòu)成(以do為例)：1. 一般現(xiàn)在時2. 一般過去時3. 現(xiàn)在進行時4. 過去進行時5. 一般將來時6. 現(xiàn)在完成時homework: explain the differences

4、 in meaning.1) i visited the giants causeway two years ago.2) it produces electricity for millions of people in china.3) ive never seen it, so im not sure i agree with you.4) i looked to the east-the sky was becoming grey.5) youll get there in five minutes.6) am i going the right way?2. ask the stud

5、ents to repeat the sentences in the box.1.一般現(xiàn)在時一般現(xiàn)在時可以用來表述或說明某一事物的特性，如上面表格的(1)；描述現(xiàn)在的狀態(tài)，如(2)。一般現(xiàn)在時還用來描述經(jīng)常發(fā)生的事情及原理，例如：thousands of people visit beijing every year.the sun rises in the east and sets in the west.注意: 1) when, until, as soon as等引導(dǎo)的時間狀語從句和if引導(dǎo)的條件狀語從句中, 若主句是將來時或祈使句, 從句則要用一般現(xiàn)在時表示將來。2）列車時刻，飛機

6、航班用一般現(xiàn)在時。2. 一般過去時一般過去時可以用來表述過去某個時間發(fā)生的事情或行為，如上面表格中的(3).一般過去時還可以用來描述事物過去的狀態(tài)或過去經(jīng)常發(fā)生的事情，例如：i was very thin in my childhood.i got up very early when i was a college student.注意： used to是過去時, 表示過去常常。e.g. i used to take a walk in the morning. 我以前常常早晨散步。3. 現(xiàn)在進行時現(xiàn)在進行時可以用來表述現(xiàn)在正在發(fā)生的事情或正在進行的行為，如表格中的(4)。現(xiàn)在進行還可以用來

7、表示已經(jīng)安排好的活動和事件。例如：my elder brother is coming tomorrow.we are having a meeting tomorrow morning.注意：go, come, leave, fly等表示位移的動詞的現(xiàn)在進行時可用來表示將來。e.g. she is flying to london tomorrow. 她明天將飛往倫敦。4. 過去進行時過去進行時表示在過去某段時間內(nèi)正在發(fā)生的事情或行動，如表格中的(5)。從例句可以看出，過去進行時常常以一個過去的行為或時間為參照。例如：i was having breakfast when he teleph

8、oned me.what were you doing at eight oclock yesterday evening?注意： while從句中的動詞只能是延續(xù)性動詞, when從句中的動詞延續(xù)性動詞非延續(xù)性動詞均可。e.g. the phone rang while / when mr. wang was sleeping on the sofa. 王先生正在沙發(fā)上睡覺時, 電話鈴響了。5. 一般將來時一般將來時表述的是發(fā)生在將來的事情或行為以及未來的狀態(tài)，如表格中的(6)。在表示對將來的預(yù)測時(沒有相關(guān)跡象表明某事必然會發(fā)生的情況下)，will和be going to可以互換。例如：i

9、t will / is going to be a rainy day tomorrow.但在其他情況下，be going to更強調(diào)計劃性，而will著重表達個人意愿或想法。例如：he is going to spend his vacation in hawaii.i will give you the information when i get it.注意：there be結(jié)構(gòu)的一般將來時常用there is /are going to be或there will be表示。e.g. there is going to / will be a film this evening. 今晚

10、將有一場電影。6. 現(xiàn)在完成時現(xiàn)在完成時與一般過去時所表示的行為都發(fā)生在過去，但是兩者表達的重點不同：一般過去時表述過去的事情，現(xiàn)在完成時則強調(diào)過去的行為對現(xiàn)在的影響，如表格中的(7)?？磳υ挘瑢Ρ葍煞N時態(tài)：a: have you seen the film?b: yes, i have.a: when did you see it?b: last night.從對話中可以看出，當(dāng)談話重心在過去的時間、地點或人物，而不是事件的結(jié)果或影響時，要用一般過去時。反之，如果我們要強調(diào)的是過去的事情對現(xiàn)在的影響，則應(yīng)該用現(xiàn)在完成時?，F(xiàn)在完成時還表示某個狀態(tài)從過去某個時間開始，一直持續(xù)到現(xiàn)在。例如：i h

11、ave lived here for a long time.i have been ill for a week.注意：have been to 曾去過某地, 表示一種經(jīng)歷have gone to 到某地去了e.g. my father has been to shanghai twice. 我父親去過兩次上海。 mr wang isnt here. he has gone to dalian. 王先生不在這兒, 他去大連了。一般疑問句式：do i / we / you / they +do? does he / she / it + do?否定句式：i / we /you / they +
