benzslk200 共回答了18个问题
|采纳率88.9%“The man we know who is a work”这句话有问题吧 主语是“the man”,“we know ”是定语从句修饰主语“the man”的(此处that省略了),“who is a worker”肯定不能做谓语,所以句中缺少谓语,应该去掉who,is系动词做谓语.后面这句主语是“we”,谓语是know ,宾语是the man,who is a worker是定语从句修饰宾语,所以是对的.此类问题首先要分析句子结构,看句子是否完整,然后再根据句意来看是否有问题.1年前查看全部

|采纳率94.4%As we know是“正如我们知道”,这个结构通常以as 作为关系代词,引导非限制性定语从句.
例如:As we know, the earth moves around the sun.这里“as”就在“as we know”这个从句中指代了“the earth moves around the sun”整个主句.
注意:As we know是定语从句,主句与定语从句的谓语表示的动作如果不是同时发生,时态则不要求一致.如:
