Avoid后是接 doing还是to do avoid doing还是avoid to do avoid 快速!是avoid to doing还是avoid to do？ avoid doing和avoid to do avoid的用法是在后面加to do 还是doing? avoid sth,avoid to do sth ,avoid doing sth avoid 到底是doing sth 还是to do sth 还是两个都有 avoid doing avoid doing和 avoid to do的区别.英语好的进来下avoid doing和 avoid to do的区别是什么呢?英语好的进来下! avoid pains 还是avoid illness? I'd like to do还是I'd like doing avoid 后面是加原形还是doing?怎么有书上是do有些书上是doing?还有为什么有的动词后面一定要加to do 比如want to do,是固定用法吗?这样的动词有几个? 有avoid sb doing吗 I'd like sb.doing sth.还是 to do sth. 有没有avoid to do怎么用?还是说要加be To avoid making mistakes,he is very careful in doing job.To avoid making mistakes 请问这个 To .的形式在语法上叫啥呢?是不定式表目的吗？ What happened to the boy?He tried (avoid) answering my questions.请问是填to avoid还是avoiding, avoid doing sth 和avoid sth有什么区别?
