their等物主代词/ ^1 P: o4 p2 Y; t7 T7 ^) G2 u3 d
1．物主代词是常见的名词限定词, 其后既可接可数名词的单复数(his pen, his pens)又可接不可数名词(his time), 但不可与其他的限定词同时出现(部分数词除外)， 例如：不能说no my car, my no car，但是可以说 My two red cars7 ]4 q7 T R [7 L: {5 E
2．英语中许多习惯用法在表示特指时都用物主代词而不用the, 为的是更突出所属关系，这在TOEFL中是一个常考的点

解释: 定冠词the指代不清, 用物主代词their作名词lives的限定语更符合英语习惯, 还可突出lives 与people之间的所属关系

解释: has是动词, 不能修饰名词, 且与从句的谓语冲突, 依句意改为物主代词its作molecules的限定语 |
