向他解释英文

explain不能接双宾语。若一定要表示“对（向）某人解释某事”，就要用explain sth. to sb.或explain to sb. sth.，介词短语to sb.是表示对象的状语；如果宾语过长，to sb.通常插在谓语和宾语之间。例如：He explained to me the rules. = He explained the rules to me. 他向我解释了这些规则。He then explained to us what it was all about. 接着他给我们解释了这是怎么一回事。

If he were here, I would have told him personally
