my brother said he --is/was-doing his homework
选什么,为什么,总结时态方法
为什么前面半句是过去时,后面就得是过去进行时,这是什么句啊,时态总结

答案：was
解析：因为主句是一般过去时,所以从句中要用过去进行时,表示当时正在做的事情.
即：My brother said he was doing his homework.
翻译：我的哥哥说他正在做作业.
有不明白的请继续追问,
再问：求宾语从句主从句时态。格式；主句。。。。。。从句。。。。。。。。。悬赏100分
再答： 1. 宾语从句的主句如果是现在时态的话，从句根据句子意思使用任何时态。例如：My teacher tells me that John got an A in the yesterday's exam. 这里从句就是用了过去式。还可以说 My teacher tells us that we will have a trip to Shaoxing. 2. 宾语从句的主句如果是过去时态，那么从句要使用过去的某种时态（过去式，过去完成式，过去进行式等）只举一个例子了，例如: My teacher told me that I had passed the exam. (告诉我之前，我考试已经通过了。考试通过发生在告诉之前，是过去的过去，用过去完成时) 3. 不管宾语从句的主句是什么时态，只要从句部分是一般真理，名言警句等的话，那么从句都是使用一般现在时。例如：My teacher told us that the earth goes around the sun. 不管怎么样，从句的语序都是陈述句语序。 PS：我现在有点事，先下机，有问题，你可以先追问，等我回来再回答，最好把这个采纳了吧，呵呵
再问：因为主句是一般过去时，所以从句中要用过去进行时，为什么，有规定吗，求解，这是什么句子啊，时态如何把握
再答：对的，除非从句中描述的是客观真理，那么就要遵循我上面说的第二点。宾语从句的主句如果是过去时态，那么从句要使用过去的某种时态，本题中从句中要用过去进行时。因为你的题中已经给出进行时的形式了，即be + doing 形式，只是取决于这个be动词是要用现在时还是过去时，当然用过去时。通俗一点说吧，这个人说话的动作发生在过去（主句中的时态有体现），那么他说话的内容（即宾语从句部分）当然也是过去发生的事情了，所以要用过去进行时，当时正在发生的。
