请问一下以下句子语法正确吗?
1、she asked me how many hours i worked last night.
2、she asked me where i went to school.
3、she asked me if i checked e-mail last night.
4、she asked me how long it took me to get here today.
5、she asked me when i

你这个.正常人不会这么问啊
1、she asked me how many hours i worked last night.正常人肯定问how long,而且要是是last night的话,应该要过去完成吧
2、she asked me where i went to school.正常人直接说where my school is
3、she asked me if i checked e-mail last night.要说谁的email,my email；还有一般会说if i had my email checked,或者if i have checked my email
4、she asked me how long it took me to get here today.是how long did it take me
5、she asked me when i没写完?
再问： 如果要用how many回答呢？应该怎样才对？ 5题如果我用when 后面应该要怎样作答，语法才对？
再答： 你说哪个用how many？asked已经是过去态了，你后面的句子就要多加一层过去式，未来式变现在，现在变过去，过去变过完 噢噢第一个继续用how many 啊，那你要说she asked me how many hours i have spend on working last night
再问： 噢！那第5题，“she asked me when i finished the lesson.”正确吗？
再答： 应该作she asked me when did i finish my lesson 你那句话的意思是，她在我上完课的时候问我
