英语的动词和情态动词的两道题
---oh,mis.wang, your dress looks nice ,is it new ?
---no,i _____ it since two years ago
a. bought b. have bought
答案是b,这里是用现在完成时.我想问的是：为什么不能够选a,看成是一般过去式.理解成,在两年前我就买了.two years ago是时间点
the old man was quite weak after the accident . so he ___-
a. must be take care of b. must be looked after
答案是b,为什么不能选a,同样是理解成“应该被照顾”的意思.
i told you not to be late again ,john , ____ i ?
a did b. didn't
答案是b,为什么不是a,在前句中,不是有一个否定的not了吗?
那么后句不是应该用肯定的吗?

这些题都有一定的迷惑性
1.,I bought it （since） two years ago ,要是a 的话就不要since啦
2.被动语态明显take 的形式不对嘛,taken
3.I told you not to be late again ,主语是I（我）,反义疑问句的肯否定判断与后面的无关啦,可以理解为I told you sth,john ,didn't
