用英语说我想帮你这句话为什么是i was trying to help you?不明白为什么用WAS不是IS?

and today she is got a headache这句话中got用过去式,为什么不是was It was his job to ripair bicycles.我不明白开始为什么用it was. i am usually tired when i get home.这句话为什么是am 不是was,get为什么不是g it is been nice to meet you?这是什么语态,为什么不是it was I was supposed to take care of him.为什么这句话要用was 不用am呢? 我不明白你为什么这样说?用英语如何说? 初中英语问题i need you to help me with my english.我需要你帮我学英语为什么help 两个英语问题,不难1.既然说“我已经六岁了”是“I am 6 years old."为什么不是用过去式"I was 6 It was getting dark.这句话翻译是：天黑了.为什么不是It is getting dark? why don\'t you ask for help,rather than trying to一句中为什么用tryi It is made in china 为什么用is 不是was to make in china I was moved by the hard work.请问这句话对不对,为什么用was 而不是am
