tony is working at a bank ____ (a)at the moment (b)a year ago (c)since last year (d)for a year谁会啊,快来教教我啊,被这个题搞晕了~~可是正确答案是b呢，所以很纳闷

I first met Tony three years ago.He ___ at a bookshop at the time.A.has worked B.was working C.had worked D.is working work for work at work in1.he is working for a big firm2.tony worked in a lawyer's office years ago3.he is now working at a bank请问可不可以互换,如果不可以的话是为什么? but he is now working at a bank. Tony saw me and came and sat at the same table.这两句话中at和a 还有at 和the ,是什么结构,为什么这么用 Tony worked in a lawyer’s office years ago,but he is now working at a bank.为什么前面用work in,后面用work at?两者的介词有什么区别? hard Tony is working —Yes. We should learn from him.A. What B. How C. What D,How a（ ）hard Tony is working —Yes. We should learn from him 关于系动词的句子分析,以及究竟如何使用的问题!在语法书上看得解释的是：说明主语性质和状态.Tony worked in a lawyer's offices years ago.Tony is now working at a bank.为什么第一句用work做动词 而第二句 Tony is ___for his test at home. Tony is good at English.You can Look at the boy.H___name is Tony. work in 与 work at 的区别Tony worked in a lawyer's office years ago,but he is now working at a bank.这里work at 与 work in 应该都可以看作在XX工作.有什么区别呢? tony is working at a bank ____ (a)at the moment (b)a year ago (c)since last year (d)for a year谁会啊,快来教教我啊,被这个题搞晕了~~可是正确答案是b呢，所以很纳闷 我写了一篇英语作文,My Best FriendI have many friend,among them,my best friend is my monitor-Tony.He looks like a famous singer and he is also very handsome.He is a hard-working student.We are good at different subjects on study.So sometimes he is now working at a bank.he is now working at a bank.和now he is working at a bank.的区别is 后面放now感觉 怪怪的 那么为什么but he is now working at a bank中却用at? Uncle Mike is working now.句中is working可用哪个替换?A.is busy B.is free C.is away D.is at work 一篇中考英语作文,给我打一下分数,同时,I have many friend,among them,my best friend is my monitor,Tony.He is a hard-working student and one of the best students in our class.We are good at different subjects.So we talk over questions t Tony is good at painting and drawing.(改为否定句）Tony【 】good at painting【 】drawing. is now working at a bankhe is now working in a bank 请问这两句意思一样吗.at换成了in
