初二英語一般將來時和過去將來時語法知識點(diǎn)(2)

　　解析：先進(jìn)題有的同學(xué)一看he做主語就用了is，忽視了will后應(yīng)加動詞原形。我們在寫句子時，很容易把動詞丟掉，“英語句子里，動詞不能少”的規(guī)律必須要牢記。第二題中to后加動詞原形，而不是用單三人稱.。

　　二、be going to +動詞原形與will+動詞原形用法不清楚

　　例：我正努力學(xué)習(xí)，準(zhǔn)備參加英語診斷。

　　I am studying hard and I will try for my English exams.

　　答案：I am studying hard and I am going to try for my English exams.

　　解析：“be going to” 表示計(jì)劃、打算要做某事。E.g. He is going to visit his friends. 還表示某種跡象表明會發(fā)生某事.e.g. Look at the clouds. It’s going to rain. 而“Will+動詞原形 ”指對將來事物的預(yù)見、表示意愿、決心。E.g. I will wait for you until you come. 在單純預(yù)測未來時，二者可以互換，但在此題中只能用be going to，而不能用will。

　　將來時的一些特殊用法

　　1)　shall用于先進(jìn)人稱，常被will 所代替。

　　will 在陳述句中用于各人稱，在爭求意見時常用于第二人稱。

　　Which paragraph shall I read first.

　　Will you be at home at seven this evening?

　　2)　be going to +不定式，表示將來。

　　a. 主語的意圖，即將做某事。

　　What are you going to do tomorrow?

　　b. 計(jì)劃，安排要發(fā)生的事。

　　The play is going to be produced next month。

　　c. 有跡象要發(fā)生的事

　　Look at the dark clouds, there is going to be a storm.

　　3)　 be +不定式表將來，按計(jì)劃或正式安排將發(fā)生的事。

　　We are to discuss the report next Saturday.

　　4)　be about to +不定式，意為馬上做某事。

　　He is about to leave for Beijing.

　　注意：be about to 不能與tomorrow, next week 等表示明確將來時的時間狀語連用

　　11.5 be going to / will

　　用于條件句時， 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 as soon as possible.

　　Now if you will take off your clothes, we will fit the new clothes on you in front of the mirror.

　　11.6 be to和be going to

　　be to 表示客觀安排或受人指示而做某事。

　　be going to 表示主觀的打算或計(jì)劃。

　　I am to play football tomorrow afternoon.　　 (客觀安排)

　　I'm going to play football tomorrow afternoon. (主觀安排)

　　11.7 一般現(xiàn)在時表將來

　　1)下列動詞：come, go, arrive, leave, start, begin, return的一般現(xiàn)在時表將來。這主要用來表示在時間上已確定或安排好的事情。

　　The train leaves at six tomorrow morning.

　　When does the bus star? It stars in ten minutes.

　　2)倒裝句，表示動作正在進(jìn)行，如：

　　Here comes the bus. = The bus is coming.

　　There goes the bell. = The bell is ringing.

　　3)在時間或條件句中。

　　When Bill comes (不是will come), ask him to wait for me.

　　I'll write to you as soon as I arrive there.

　　4)在動詞hope, take care that, make sure that等后。

　　I hope they have a nice time next week.

　　Make sure that the windows are closed before you leave the room.

　　11.8 用現(xiàn)在進(jìn)行時表示將來

　　意為："意圖"、"打算"、"安排"、常用于人。常用詞為 come, go, start, arrive, leave, stay等。

　　I'm leaving tomorrow.

　　Are you staying here till next week?
