动词 when 和 while 的选择:when 后加瞬间动词,while 后加延续性动词。

重点语法
宾语从句
结构:主语 + 谓语动词 + 宾语从句(主语 + 谓语动词 + 宾语/表语)
1、引导名词性从句的连接词
(1)that:没有含义,在宾语从句中不做成分
(2)whether/if:表示是否,宾语从句中不做成分。
I don't know if /whether he still lives here after so many years. 我不知道这么多年后,他是否还住在这里。
(3)连接代词:what, which, who, whom, whose(在宾语从句中做主、宾、表和定语)
连接副词:where, when, how, why(在宾语从句中做状语)
2、在做宾语从句的题目时应注意时态
(1)当主句是现在时态时,宾语从句可以根据需要使用任何时态。
He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。
