13.Some students think it is ___ to spend some time surfing the Internet,but we shouldn't be too dependent on it.( )A. | worth | B. | worthwhile | C. | worthy | D. | worthy of |
分析 一些学生认为花些时间上网是值得的,但是我们不应该太依赖于它.
解答 答案是B.本题考查形容词词义辨析.worth值得的,常用的结构是be worth doing值得做,worth后不接to do,所以排除A;worthwhile值得花时间的,常用结构It's worthwhile to do/doing表示"值得花时间做…",其中it是形式主语;所以答案选择B.worthy值得的,往往用于结构"be worthy of being done"或"be worthy to be done",不用it做形式主语,所以C和D不符合本题;
点评 辨析形容词要在识记常见形容词及其搭配的基础上理解语境,根据具体语境推断合理的答案.
