再来，坚持重在积累，重在用······
一、each，every
each
eg：Each of my children goes to different schools.
归纳：表示两者或两者以上的人或事物中的“每一个”，强调个体。every
eg：Every child in the class passed the exam.
归纳：表示三者或三者以上的人或事物中的“每一个”，强调整体。
注意：every以及everyone，everybody，everything等与not连用表示部分否定。
eg: I don't know everything about her.
二、other，the other，another，others
other
eg：He has no other close friends like John.
归纳：表示“其余的，另外的”，不能单独使用，必须与any，some，no等连用。the other

归纳：可单独使用，指“两者中的另一个”，也可修饰名词。another
eg：She will stay here for another 3 days.
归纳：表示“又一个”，指代或修饰单数可数名词。但若其后有数词或few修饰时，则可接复数可数名词。others
eg：Some books are to be tasted, others to be swallowed(吞没), and some few to be chewed and digested.
归纳：表示复数意义，相当于“other+可数名词复数”，表泛指；the others 相当于“the other + 名字的复数”，表特指。
三、one，ones，the one，the ones，that，those
one
eg：Mr. Zhang gave me a very valuable present，one(= a present) that I had never seen.

归纳：ones 用来替代前面出现的复数名词，也是泛指。the one
eg：The book on the desk is better than that/the one(=the book) under the desk.
归纳：the one 用来替代前面的特指的单数名词，有时可用that替代（尤其在有后置定语的情况下）。the ones
