1、语法1（冠词）一基础知识（1）.It代替前面的事物本身。它可以代替可数名词，也可以代替不可数名词。代替可数名词时，复数形式为they/ them.没有增加语义，所以不能带有任何定语。（2）、 one可以代替与前面同类不同一的事物；可以代替某类事物中的任何一个；可以做同位语，重复指代前面的事物，其后有定语从句用以进一步说明前面的名词。one表泛指，相当于a/an+名词。one只能代替可数名词，其复数形式是ones。one可以根据语义在它的前面或后面加上一些定语。one前面不能直接加不定冠词（a / an）或物主代词，one前已经有形容词时，则可以加不定冠词或物主代词；one前加the与否，取决于
2、是否特指，如果特指就加the。one既可以代指物，也可以代指人。（3）、 that代替与前面同类不同一的事物。that表特指，相当于the+名词。它可以代替可数名词，也可以代替不可数名词。代替可数名词时，复数形式为those。二习题演练1.
