2、表示做某事很开心,可用have (there is) fun (in) doing sth。如:we had fun riding our bicycles to the beach today. 我们今天骑自行车去海滨玩得很开心。
3、fun虽用作表语,但仍为名词,而非形容词,故可用great, much, a lot of等形容词修饰,而不用very等副词修饰。如:she’s great fun to be with. 同她在一起很有意思。
4、fun前的more为much的比较级。如:it is more fun to go with someone than to go alone. 偕伴同去比自己独自去好玩。
