My bother came back while I_____homework.A.am doing B.was doing C.do .D,did(选什么并给予详细回答)
B was doing
当你兄弟回来时是过去式,所以后面形容我在做作业时也是过去时,因为是while 表明是与你弟弟回来同时发生的事情,所以是进行时,加起来就是过去进行时啦~
B.was doing
句子的意思是说我弟弟回来的时候,我正在做作业
正确:B (句意:妈妈回来时,我正在做作业。while后常接延续性动词,从句意体会得到使用进行时,又came体现过去式,故使用过去进行时。)
was doing.come back 说明是过去时,要用过去式。另外,当我正在做作业时,我哥哥回来了。
B
由came知道应该是过去式,排除A,C,而由while引导时间状语从句知道应该是过去进行时,表示恰好在过去的某一时间发生了特定的动作,即本句 (之前)我正在做作业的时候我哥哥回来了。
选择B,主句用过去时,从句用过去进行时。
应该选b
came back 是过去式,前后时态应一致,所以排除a,c
而且while表示的是当...时候,所以应该是用进行时态,而且是过去进行时态
