Question

It is _____ he often fails in exams____ makes his parents worried about him.

A．because；that	B．that；that
C．不填；that	D．what；that

Answer 1

B

試題分析：考查主語從句和強調(diào)句：首先第二個填that為強調(diào)句，It is ...that...中的that 為固定搭配，去掉It is ...that...來看，這是句子為That he often fails in exams makes his parents worried about him.在這一句中That he often fails in exams 為主句，這是個強調(diào)的主語從句，選B。
