新概念英语1 139
1课文She invited Charlotte and me to dinner this evening.
我写的she invited charlotte and me to have dinner this evening对吗?invite sb to sth还是invite sb to do?还是这两个词组都有?
2课文 but the boss want me to do some extra work.
但老板要我加班.
我写的but boss asked me to do extra work.老板要求下属,应该用ask更恰当吧?want力度不够啊.不加some从语法上来说成立吗?为什么不用过去式?课文此时是在叙述不能按时回家的原因,老板要求加班已经是过去要求的动作了,课文怎么不用过去式?
3课文 I said I would be at your house at six o'clock,
我说过我6点到你家,
为什么would后面不加arrive而用 be呢?would arrive at your house可以吗?
