Another reason is too much emphasis is put on difficult prob

2个回答

  • 这句话主干是:Another reason is (that).

    is 后面是一个完整的句子做主句的表语,就是说,后面是that 引导的表语从句.

    由that引导的表语从句如:

    The trouble is that he misunderstood me.麻烦的是他误解了我 that是不可以省的

    有时,引导表语从句的连词that可以省略

    The truth is (that) I didn’t finish my term essay.事实是我没有写完学期论文.
