make doing还是to do

　　都可以，make后面可以加to do也可以加doing。make为使役动词,其后跟省略to的不定式作宾语补足语;在被动语态的句子中，则要还原不定式的符号to。

　　(1) make后面跟动词原形表示使某人做某事。

　　Our teacher made us get to school before 7:30.我们老师要我们7：30前到校。

　　The landlord made the workers work 15 hours a day.地主让工人们一天干十五个小时活。

　　【注意】把make sb do sth变为被动语态的时候应该加上to，即 变成be made to do sth。请看：

　　His father made him come back home on time.

　　=He was made to come back home on time by his father.

　　The joke made us laugh .

　　=We were made to laugh by the joke.

　　(2)make后面跟形容词表示使某人/物处于······状态。

　　The death of my cat makes me very sad. 我的猫的死亡让我很难过。

　　Books give us knowledge and make us happy. 书不仅给我们知识，而且使我们快乐。

　　The music made me very relaxed. 音乐让我非常放松。

　　This is where we make doing that a bit easier.

　　这是我们作出这样做更容易一些。

　　To make doing business easy.

　　让天下没有难做的生意!

　　I need a little while more, and I believe I can make hard to do better.

　　其余的不多说了，我需要多点时间。我会努力做到更好的。
