e. g. sit wherever you like.
make a mark where you have a question.
4. 目的狀語從句
引導目的狀語從句最常用的詞（組）是so, so that（從句謂語常有情態動詞）, in order that, in case（以防，以免）等。
e. g. speak clearly, so that they may understand you.
she has bought the book in order that she could follow the tv lessons.
he left early in case he should miss the train.
5. 結果狀語從句
結果狀語從句是表示事態結果的從句，通常主句是原因，從句是結果。由so that （從句謂語一般沒有情態動詞）, so … that, such … that等引導。
e. g. she was ill, so that she didn’t attend the meeting.
he was so excited that he could not say a word.
she is such a good teacher that everyone admires her.
6. 條件狀語從句
條件狀語從句分真實性（有可能實現的事情）與非真實性（條件與事實相反或者在說話者看來不大可能實現的事情）條件句。引導條件狀語從句的詞（組）主要有if, unless, so (as) long as, on condition that, so (as) far as, if only ( = if )。注意：條件從句中的if 不能用whether替換。
e. g. if he is not in the office, he must be out for lunch.
you may borrow the book so long as you keep it clean.
so far as i know（據我所知）, he will be away for three months.
you can go swimming on condition that ( = if ) you don’t go too far away from the river bank.
if he had come a few minutes earlier, he could have seen her.
7. 讓步狀語從句
讓步狀語從句可由although, though, as, even if (though), however, whatever, whether … or, no matter who (when, what, …) 等引導。注意：as引導的讓步狀語從句一般是倒裝的。
e. g. though he is a child, he knows a lot.
child as he is, he knows a lot.
whatever ( = no matter what ) you say, i’ll never change my mind.
8. 方式狀語從句
方式狀語從句常由as, as if (though), the way, rather than等引導。
e. g. you must do the exercise as i show you.
he acted as if nothing had happened.
9. 比較狀語從句
比較狀語從句常用than, so (as) … as, the more … the more等引導。
e. g. i have made a lot more mistakes than you have.
he smokes cigarettes as expensive as he can afford.
the busier he is, the happier he feels.
10. 使用狀語從句時要注意的幾個問題
（1）在時間和條件（有時也在方式、讓步等）從句中，主句是一般將來時，從句通常用一般現在時表示將來。
e. g. we’ll go outing if it doesn’t rain tomorrow.
i’ll write to you as soon as i get to shanghai.
（2）有些時間、地點、條件、方式或讓步從句，如果從句的主語與主句的主語一致（或不一致，是it），從句的謂語又包含動詞be ，就可省略從句中的“主語 + be”部分。
e. g. when (he was) still a boy of ten, he had to work day and night.
if (you are) asked you may come in.
if (it is) necessary i’ll explain to you again.
