1.that 引导定语从句,修饰先行词books,即that指代more than 100 books . that作定语从句的主语2.that 引导定语从句,修饰先行词plant and animal life-forms ,即that指代plant and animal life-forms ,that作定语从...谢谢 你说的很对 但是我搞不清第一题that为什么不指代author或boys,他们也可以focus on theme 第二题为什么不是指代variety第一题:意思是那100多本书的主题。。/ 。不是作者、孩子们的主题第二题:that 后的谓语是are,,显然that不是指代a variety (单数名词)请采纳
