let sb to do和make sb to do
make在什么情况下后接todo？
make在什么情况下后接todo？
应该是make sb do sth。 因为make是使役动词，后面接sb，再接动词时，需要用动词原形做宾语补足语。 make sb do：让某人做某事。 分析：这是一个动词短语。 make （动词）sb （宾语，用宾格）do（宾语补足语）。 例如： In order to make him accept our suggestion, I decided to work on him immediately. 为了让他接受我们的建议，我决定立刻对他做工作。 Make him do some eye exercises after studying, which would be really good for his sight. 让他在学习完之后，做一下眼保健操，这对他的视力很有好处。 Then put his hands on your sensitive part, which may give him confidence that you need him and make him carry on. 然后把他的手放在你身体的敏感部位，这既可以给他信心，也表明你想要他，鼓励他做下去。
make 和make 有什么区别呢？
make sb do sth是使某人做某事的意思，sb是主动make sb done是使某人被做某事。sb是被动e.g. The teacher made Tim clean the classroom because he made father made his son beaten.在大多数词组中，do 表示主动或表示一种过程，doing 表示正在做或表示一种主动，done 表示被动或者是已经完成了。
she wore high-heeled shoes to make herself look a bit taller. 她穿了高跟鞋，使自己看起来高一点。首先，look，seem, appear等作表象系动词时与sound，smell，feel，taste等作表示感觉的感官系动词时有一样用法，即后面接补足语可直接接形容词，表示‘...起来怎么怎么样’。这类系动词无被动形式，只随时态变化。如：she looks pretty.她看起来很美。Tom seemd(to be)very sad. Tom看来很伤心。it sounds great.听起来棒极了。He felt tired.他觉得累。然后make sb do sth使某人做某事，当sb后面接上述系动词表示‘使某人看起来/闻起来/感觉...’时，系动词按make sb do sth的固定词组使用原形即可。
