状语从句

使用状语从句有两点要注意：一是状语从句中连词的选用，二是条件状语从句中的时态。

1.状语从句中连词的选用。

状语从句中连词的选用是由句子所表达的逻辑意义决定的。只要知道各种连词的意思和功能就能正确使用。

常用的有：

(1) 时间状语从句连词：when, while,  as, before, after, until, as soon as 等。

例如：My father took the photos when we lived in Hong Kong.

You’re not going out until you’ve finished this.

(2)地点状语从句连词：where

例如：We must camp where we can get water.

(3)条件状语从句连词：if

例如：If he leaves the vegetables with the goat, the goat will eat them.

(4)比较状语从句连词：than, as

例如：The cost of the repairs was a lot of cheaper than I thought.

(5)目的状语从句连词：so that, in order that

例如：I’ve brought some photos so that you can see what Britain looks like.

(6)原因状语从句连词：because, since, as

例如：Mark could not come because he had to work.

(7)结果状语从句连词：so … that …

例如：He got up so late that he missed the first train.

(8)让步状语从句连词：although, though

例如：Although the car is old, it still runs well.

2.条件状语从句中的时态

在条件状语从句中，如果主句的时态是一般将来时，从句一般用一般现在时。

例如：If it rains tomorrow, we will play inside.

不定式

1.作动词宾语

放在谓语动词之后的不定式作谓语动词的宾语。

如: want to do sth., agree to do sth.,    decide to do sth. 等结构。

例如：I decided to join some student clubs and take part in as many activities as I could.

2.作宾语补足语

不定式作宾语补足语是指v. 名词/代词 (to) do sth.结构中的不定式。变否定时只需在不定式前加not，其中的to在某些动词后面需省略。

3.作目的状语

不定式还可以作目的状语。不定式作目的状语时，可以放在句末和句首。

例如：He got up at five o’clock to catch the early bus.

To watch baseball, you need to go to the Yankee Stadium.
