选D
如果选择c的话,what 和that就重复了,这个地方用what 或that引导的都是名词性从句。
如果要正确的话那就吧c选项的what和that反过来,用that做连词,而what引导从句。所以选择D,应道从句的是that
翻译过来就是:接下来史密斯先生告诉我为什么他正在做的事情那么重要。
what
因为Mr. Smith told me后面要接上一个名词
told sb sth.
what引导后面的he was doing was very important
意思为:Mr. Smith跟我说他做的东西非常重要。
答案错了。请相信自己。
答案错了,应该是(that可省)what
前面是宾语从句Mr.Smith told me (that)
后面是主语从句what引出he was doing
C.what that that 可以省
应该是what...没that吧
c
