that , if / whether , what , who , which , whose , when , what

等的用法,以及宾语从句的时态。
在复合句中作主句的宾语,叫宾语从句。
注意:宾语从句的语序必须是陈述句语序。
e.g. I asked him if he was a student.
宾语从句的时态呼应是:主句的时态是一般现在时,从句可以是任何一个时态。
如果主句的时态是一般过去时,从句必须是过去时态的一种形式。
当表示事实、真理、自然现象时必须用一般现在时。
e.g. The teacher told us that the earth goes around the sun.
老师告诉我们地球围绕太阳转。
请注意防止出现以下错误:
A. They said that they'll leave if Peter stays.
时态错误,应改为:
They said that they would leave if Peter stayed.
B. He asked why were you late for school.
语序错误,应改为:

C. Her brother asked me whose book this was ?

s , until , because , than , if , so …that
等词引导的时
间、原因,比较,条件、结果状语从句。

校长高声讲话为的是全体学生能够听到他所讲的话。
让步状语从句:

虽然他年龄小,但却认识许多事情。
状语从句的时态要与主句时态相互呼应。但要注意以
as soon as , when , until
等引导的时间
状语从句表示将来的动作时,从句要用一般现在时表示将来。
e.g. He will write to me as soon as he gets to America.
他一到美国就给我写信。
When I see him , I will tell him this good news.
当我见到他时,我将告诉他这个好消息。

直到完
成作业我们才会离开。
以
if
引导的条件状语从句假设 的是将来的动作,主句用一般将来时,从句用一
般现在时。
e.g. He will come to see me if he has time.
如果条件状语从句放在宾语从句中,时态则依照宾
语从句的要求而变。
e.g. My mother said she would buy me a book if I studied hard.
我母亲说如果我努力学习,她要给我买一本书。
以
because
引导的原因状语从句不可能和
so
一起连用。
e.g. He didn't come to school yesterday because he was ill.
他昨天没来学校,因为他生病了。
注意防止出现以下错误:
A. I'm sure he'll ring you up if he will come back.
从句时态错误,
will come
应该改为
comes.
B. Because he was tired , so he went to bed very early.
中文习 惯用
“
因为
……
所以
……”
,
但在英语中
because
不能和
so
同时使用,
应该去掉其中的
一个。
