小學(xué)英語(yǔ)語(yǔ)法 一般將來(lái)時(shí)
一般將來(lái)時(shí)主要用于：
表示將要發(fā)生的動(dòng)作或情況
e.g. Tom will have a bike of his own.
與這個(gè)時(shí)態(tài)連用的時(shí)間狀語(yǔ)常用：
tonight, tomorrow, the day after tomorrow, next week, in three hours, two days later 等。
一般將來(lái)時(shí)態(tài)與其它結(jié)構(gòu)表將來(lái)情況的區(qū)別：
一般將來(lái)時(shí)態(tài) ：主要從時(shí)間的角度表將要發(fā)生的動(dòng)作或情況。
be going to 結(jié)構(gòu) ：①表（主觀上）打算或準(zhǔn)備做某事時(shí)。 ②表有發(fā)生某事的預(yù)兆時(shí)。
e.g. They are going to have a competition with us in studies. It is going to rain.
據(jù)以上區(qū)別，故下面一句是錯(cuò)的：
I am going to be eighteen years old next year.
應(yīng)改為： I shall be eighteen years old next year.
be about to do sth 結(jié)構(gòu) ：意為"剛要做某事"、"馬上要做某事"強(qiáng)調(diào)時(shí)間之緊迫性。
e.g. We are about to discuss this problem.
小學(xué)英語(yǔ)語(yǔ)法 一般過(guò)去時(shí)現(xiàn)在完成時(shí)
一般過(guò)去時(shí)現(xiàn)在完成時(shí)主要用于：
1 、表示到現(xiàn)在為止這一時(shí)期中發(fā)生的動(dòng)作或情況，即多次動(dòng)作的總和。
e.g. We have learnt four English songs this month.
How many times have you read the novel?
For many days we haven`t seen each other.
2 、表示對(duì)現(xiàn)在有影響的某一已發(fā)生的動(dòng)作。
e.g. The delegation has left 代表團(tuán)已經(jīng)走了（說(shuō)明現(xiàn)在不在這里）
Look, what you have done. 看你干的事。
與這一時(shí)態(tài)連用的時(shí)間狀語(yǔ)有：
already, yet, just, ever, never, by now, so far, recently, by the end of this month, since, for 短語(yǔ)，連詞 since 引導(dǎo)的時(shí)間狀語(yǔ)從句。
一般過(guò)去時(shí)與現(xiàn)在完成時(shí)的區(qū)別：
一般過(guò)去時(shí)：重在說(shuō)明動(dòng)作在過(guò)去發(fā)生時(shí)的具體情況（時(shí)間、地點(diǎn)、方式、對(duì)象、細(xì)節(jié)等）。
現(xiàn)在完成時(shí)：只提起已發(fā)生的動(dòng)作（事實(shí)）及其影響，不說(shuō)明動(dòng)作發(fā)生時(shí)的具體情況。
cf. Have you had your lunch?
What did you have for lunch?
I have ever been to the Great Wall,_and_I went there last summer with my father.
注：現(xiàn)在完成時(shí)表達(dá)的動(dòng)作常具有反復(fù)性，故下面一句是錯(cuò)的：
Have you seen the six thirty`s news program?
應(yīng)改為：
Did you see the six thirty`s news program?
