5. I have some doubt ________ he
will win.
(六)同位语从句和定语从句的区别
1.定语从
句是先行词的修饰语,它不涉及先行词的具体内容。定语从句中that不但
起连接作用,而且在定语从
句中充当一个句子成分,充当从句的宾语成分时可省
略。
2.同位语从句对中心词
的内容作进一步的解释和说明,表明中心词的具体内容。引
导同位语从句的that
在同位语从句中不做任何成分,只起连接作用,无具体含义,且
不可省略.
1).We
expressed the hope that they had expressed.
2). We expressed the hope that they would come
to China again.
1).The information has been
announced that more middle school graduates will
be
admitted into university.
2).The
information that he revealed at the meeting is of
great value.
3.名词demand, suggestion,
proposal, advice等词后的同位语从句的语气要用虚拟语
气,结构为 should
+ do, should 可省略
He gave me a suggestion
that I ( should ) be calm now.
(七)注意宾语从句中的时态呼应
当主句动词是现在时,从句根据自身的句子情况,而使用不同时态。
例如:
I
know (that) he studies English every day.
(从句用一般现在时)
I know (that)he studied English
last term. (从句用一般过去时)
I know (that) he will
study English next year. (从句用一般将来时)
he has
studied English since 1998. (从句用现在完成时)
当主句动词是过去时态(could, would除外),从句则要用相应的过去时态
例如:
The teacher told us that Tom had left
us for America.(从句用过去完成时)
The teacher told us
that Tom was sleeping.(从句用过去进行时)
总结:主句:现在时,从句:啥时态都可; 主句:过去时,从句:过去时
