instead of, in place of与take the place of

①instead of是介词短语，意思是“代替”，“而不是”，作介词短语后接名词、动名词和宾格代词;作连词短语后接不定式(一般不省略to)，谓语动词、形容词、副词和介词短语等。如：John will attend the meeting instead of his manager.约翰将代替经理出席这次会议。You should have some exercise instead of staying indoors all day long.你应多锻炼身体，不要整天呆在家里。The temperature has risen up instead of fallen down.温度上升了而并没有下降。This is dull instead of interesting.这不但没趣，反倒枯燥。

②in place of介词短语“代替”，通常后接名(代)词，可与instead of互换。如：People often use plastics in place of/instead of wood or metal.人们常用塑料来代替木材和金属。但instead of sb./sth.可略去介词of及其宾语，而in place of通常不能将其省略。

③take the place of动词词组，“代替”(职务，工作等)，如：Most scientists agree that computers can’t completely take the place of humans.大多数科学家认为，计算机并不能完全代替人。作“代替”解时，不可将the去掉或改换为one’s，那样会引起歧义，要注意区分。
