从句后加延续性动词的现在进行时,但主从句都是现在进行时的,可以吗,表什么,作选择题时,如何抉择。可以吗,可能表达不好,如果解释清楚,那真的要谢谢了。while mary was dong her home work ,the other children _______outside.就如上述题,应填啥时态,现在进行,还是一般进行,我就在这搞不懂,谢谢
可以!
while接时间状语从句,当。。。时。。。。, 从句一般情况下用进行时态,主句可以是进行时,也可以是简单过去时。
While I was climbing the stairs, the doorbell rang。
While I was eating, Tom called me。
While we were watching a basket game, our father was listening to the radio。
I was reading book while my son was playing outside。
但是主句不能是现在(或者现在进行)时态。 否则逻辑混乱。
有时候,主从句全用过去式:
While I read, she sang。
我看书时,她在唱歌。
while mary was dong her home work ,the other children were playing outside。
最恰当! 过去进行,因为在描述的时候,这些动作都已经过去了。
。
当然可以 while 引导得从句必须是具有延续性的 主句则随便,不过很多时候用进行时
可以如While John was sitting biting his nails, I was working out a plan to get us home. 约翰坐在那里咬指甲时,我想出了一个回家的办法。
你可以先弄明白while和when的用法啊!
主句的动作发生在从句之后用when ,当从句的谓语动词表示状态时用when ,when:放两个从句,while:放一个从句。
⒈when和while都可以作从属连词,表示时间:a。when的含义是at or during the time that,既可用于一点时间(从句的谓语动词需用终止性动词),也可用于一般时间(从句的动词用延续性动词,从句与主句中的谓语动词所表示的动作或状态能同时发生或一前一后发生。
b。while的含义是during the time that ,只能用于指一般时间(从句的谓语动词必须是延续性动词,从句与主句的谓语动词所表示的动作只能同时发生,不能一前一后发生。
⒉这两个词可用作并列连词。a。when意为“在那时”,“这时突然”,用来连接两个并列从句。 b。while意为“而;却”,表示对照关系。

可以的 while mary was dong her home work ,the other children _(were playing) outside. 或者while mary was dong her home work ,the other children (were)outside
