1. 一般语法
1）两个动词不能连在一起用
2）如一定要同時用兩個動詞,後者的前面必須加“to”或者將後者加入“ing”。
I love to swim.
I love swimming.
---------------
I hate to eat fish.
I hate eating fish.
---------------
I love to play basketball.
I love playing basketball.
3) 主詞如果是第三人稱,現在式及單數,動詞必須加 s
以下的句子都是錯的。
* He write very well.
* Jack love playing the violin.
* Mary swim every day.
正確的句子是:
He writes very well.
Jack loves playing the violin.
Mary swims every day.
1. 現在完成進行式
如果有一個行動，從過去發生後，就一直延續到現在，我們可以用現在完成式。
verb to have + been + present participle(现在分词)
（1） 自從1974 年，我就在學校學英文。
Since 1974, I have studied English at school.
（2） 自從我大學畢業以後，我就在這裡工作。
Since I graduated from college, I have worked here.
2. 過去完成進行式
had + past participle
過去完成式是不能單獨用的。我們用的時候，必須有另一個事件。也就是說，假如我們有兩件事 A 和 B，兩件事都發生在過去，但 A 發生在 B 以前，A 應該用過去完成式，B 則用過去式。以下是幾個例子：
（1） 他到台灣以前，曾學過中文。
He had studied Chinese before he came to Taiwan.
|<--- A ------>| |<-- B -->|
（2） 他唸大學以前，曾前工作過。
He had worked before he decided to go to college.
|<-- A -->| |<-- B -->|
------------------------------------------------
Before之前用过去完成式，之后过去式。
（3） 週一以前，已經下過雪了。
It had already snowed before Monday.
3. 未来式
a. will
I will call you tonight.
He will graduate next June.
Mr. Lee will teach us English soon.
It will rain tonight.
b. verb to be +going to+ verb
I am going to call you tonight.
He is going to graduate next June.
Mr. Lee is going to teach us English soon.
It is going to rain tonight.
有一個規則必須注意,就是 will 是一個助動詞,現在式第三人稱
單數的主詞,仍不用在 will 後面加 s。
3.1 未来进行式
未來式可以和進行式合起來用,以下是未來進行式的例子
I will be watching TV tomorrow at eight.
Two days later, I will be driving a new car.
主语 + will be + 现在进行时
3.2 未来完成式
未來式可以和完成式合在一起用,而成為未來完成式,這種句子
都是在於強調未來要完成的事。
I will have finished this work by six o'clock tomorrow.
He will have written six novels next summer.
We will have had three meetings before six o'clock tonight.
