when ,while,that在用的时候的区别 这种句子好像叫定语从句
解题思路: when ,while,that在用的时候的区别
解题过程:
when 和while的用法区别
两者的区别如下:
①when是at or during the time that, 既指时间点,也可指一段时间;
while是during the time that,只指一段时间,因此when引导的时间状语从句中的动词可以是终止性动词,也可以是延续性动词,而while从句中的动词必须是延续性动词。
②when 说明从句的动作和主句的动作可以是同时,也可以是先后发生;while 则强调主句的动作在从句动作的发生的过程中或主从句两个动作同时发生。
③由when引导的时间状语从句,主句用过去进行时,从句应用一般过去时;如果从句和主句的动作同时发生,两句都用过去进行时的时候,多用while引导,如:
a. When the teacher came in, we were talking.
当此句改变主从句的位置时,则为:
While we were talking, the teacher came in.
b. They were singing while we were dancing.
④when和while 还可作并列连词。when表示“在那时”;while表示“而,却”,表对照关系。如:
a. The children were running to move the bag of rice when they heard the sound of a motor bike.
孩子们正要跑过去搬开那袋米,这时他们听到了摩托车的声音。
b. He is strong while his brother is weak.
他长得很结实,而他弟弟却很瘦弱。
that的用法太多了,可以引导宾语从句,表语从句,主语从句,定于从句。在宾语从句和表语从句中可以省略,在主语从句中绝对不能省略,在定语从句中作主语不可省略,做宾语可以省略。定语从句的关系代词 that的用法: 若先行词指人或物则代替先行词在定语从句中充当主语或宾语
The animal that which is lost is a panda.
先行词 指物代替先行词在定语从句中充当主语
She is the person that who we are worried about.
最终答案:略
