2、，引导同位语从句只能用that, 这句话对吗？先看下面几个句子。1 I have no question that he will come.2 I have a question whether he will come3 I have a question when he will come.我们可以看出：上面三个句子中question后面都是同位语从句，都是说明question的内容的。在句中，同位语从句的原句是陈述句，由that引导；在句中，原句是一般疑问句，由whether引导；在句中，同位语从句的原句是特殊疑问句，特殊疑问词也起着连接作用。其实，所有名词性从句的连接词都有上面的三种

19、that whether he could get a job at the center.2 You have no idea that how busy we were those days.3 It is well known what a person eats causes changes in the body.答案及解析：去掉that,。后面whether本身就起着连接作用。去掉that。 who, how, when, what等本身就有两个作用：作从句的成分；起连接作用。在what前面加that。what只是把主语从句的两个分句连接起来，但其作为一个整体来作主语从句时还需要用
