You should say "Thank you"when someone passes you the salt on the table,when someone walking before
you keep the door open for you,when someone says you have done your work well,you have bought a nice thing,or your city is very beautiful.(1~2)
1.为什么when someone says 中用says而不用saying,况且上文也有when someone walking before you keep the door open for you
(难道是句中的before 可是都是介词后的动词加ing呀)
2.为什么when someone walking before you keep the door open for you中要用keep而不用keeping,句子中不是有before吗
3.Have your parents flown to Shanghai?
Yes.They went there to see the fashion show.
问句中为什么用现在完成时,答句中用过去时.
You should say
1.句中的时态是一般现在时,when引导时间状语从句,在时间状语从句中将来时态都要用现在时代替;
2.when someone walking before you 中”walking before you“是修饰someone的,意思是“走在你前面的人”,强调状态,所以是进行时态,walk并不是谓语,而keep才是someone的谓语,是不是忘了加"s”了.所以要耐心的分清句子结构,不然就搞混了.
3.问句强调到了没有,在答句中其实是做了相应的回答的,完整的应该是yes,they have.说明我的父母已经到过上海了.后面一句是一般过去时,表达另外一个意思,说明他们当时去那里的目的,所以是一般现在时.
希望以上的能帮到你!
