_____Zhao hai today?Yes.It is hour.Just an hour ago.
Do you know why he _____ this evening He told me he had an important meeting to attend.
为什么是have you seen; isn't coming,而不是did you see;wasn't coming
这个today请详细解释下
______ you ______ the editor at the airport?No,he ______ away before my arrival.
为什么这道题第一个空就不是Have.met而是did.meet呢?
When I was young,I ______ to school everyday.
为什么答案是was walking,而不是walked呢?
感谢你们的回答!

这个today是指今天.题目的意思是指向今天之内你看见赵海了没?
所以不是过去时,用isn't coming.而另一种问法是你今天看见过赵海没,强调的是已经见过他了没,所以是现在完成时,用have you seen.
第二题,注意动词meet ,也就是题目意思是你和编辑在机场碰面了没有,是碰面的动作,这个动作不是延续性动词,所以不用完成时,用did you see 比较符合.
第三题,was walking,强调的是那一段时间之中都是走路去上学,而不是某一次走路去上学过,所以用过去进行时.这种句子里面的be动词+doing是指那段时间内从事的活动~
楼主仔细体会一下就熟悉了,语感是很重要的.希望你越学越好哈.

第一题没什么错误，答案正确，today在题目中没有意义可以替换为yesterday或其他时间状语。do you know所以用isn't coming
如果单独第一空的话两个都可以，但是结合后句意思“他已经离开了”可以了解到后句一定用完成时，he has been所以前后时态一致
was walking代表过去一时期的习惯动作，或者也可以用used to walk...

收起

一 你今天见过赵海吗？ today是时间副词，说话者是问在今天过去的时间里见过没有，所以用完成时。this evening 表示将来时态，今晚还没到。所以用is
二 这是对完成时态定义 一般过去时定义的考查，建议你好好看看
三 答案错了 就是walked
