是这样的：shaped so smoothly and perfectly 前面还有airplanes，若不加明确的名词，会导致后面的修饰了它。类似题目的具体讲解在OG语法中，第二题和有一道讲沉积物与该地区工业发展两题中有详细解释。请参阅！作者: princess 时间: 2002-9-6 14:37
我来试两道
5.不加wings的话,shaped可以修饰前面的airplanes啊,
6.D的意思就变成了Beatrix Potter was coordinated with her narratives,呵呵,前半句的逻辑主语和主句不一致了
7.but连接的两个句子是并列关系,因此两个句子都要有完整的主谓结构,A不符合这一条件
8.比较的两个物体应该具有可比性.比如说amount和figure相比较.C中比较的两个对象是sale和figure,不可比.
9.前后两个分句之间不是转折关系
10.在选项同时有can(could)和be able to的时候,GMAT好像偏向于can.这个解释有点牵强.不过我觉得be able to更多的时表示一个人的能力,如果说computers有这种被programed like people的能力,恐怕不行吧作者: tongxun 时间: 2002-9-6 14:47
