(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。

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.

2). We expressed the hope that they would come to China again.

admitted into university.

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
