[词条1] contain

●contain还可意为“控制，克制（感情）”等。例如：

①When receiving the letter of acceptance to the university, I was unable to contain my excitement.

②He was so angry that he just couldn’t contain himself.

●辨析contain，include和hold：contain着重指“内有”，表示包括的内容或成分，被包含的东西既可有形，也可无形；include着重指被包含者只是整体的一部分；hold作“容纳”讲时，主要指容量。例如：

①This drink is safe for the children; it doesn’t contain any alcohol.

③How many people can this hall hold?

●affect和effect都有“影响”的意思，它们的区别是：affect当“影响”讲时是动词；而effect当“影响”讲时则为名词，常用于短语have an effect on，意为“对……有影响”。effect 作动词时意为“引起，使发生”。例如：
