问题描述：
Tom didn't attend the lecture yesterday evening _ his illness.
A as B.for C.because D because of
答
D因为生病，because后加句子because of后加短语
答
为你解答。
Tom didn't attend the lecture yesterday evening （D because of） his illness.
昨天汤姆没参加这个讲座是因为病了。
解释：as, for, because都可以表示原因，但它们都用于引导从句。但因为这一空的后面是个短语而不是句子，只能用because of来连接。
答
选择D.
because of 后接名词短语
his illness 是名词短语
as和because后接句子,就是有面有主语的句子
我们也可以说,
Tom didnt attend the lecture yesterday evening,because he was ill.
