关于"is"后紧跟动词用法的困惑
what i do in this period is keep in touch with you ...
what you do is send it directly to me in my department ...
这两句话中都出现了"is"后紧跟动词:keep send
这是种什么用法 感觉很奇怪
是雅思剑5听力中的原话

Answer 1

这两句没有错,都是主---系---表的结构:
1)what I do 是主语从句(作句子的主语),is 是谓语,
keep in touch with me 是不定式短语作表语(现在流行不定式作表语时前面不加 to);
2)what you do 主语(也是主语从句)
is 谓语
send it...(也是不定式作表语)
