7.Stephen Hawking believes that the earth is unlikely to be the only planet life has develop gradually.( )A. | that | B. | where | C. | which | D. | whose |
分析 句意为:斯蒂芬•霍金认为,地球不大可能是有生命进化现象的唯一星球.
解答 答案:B,本题考查定语从句的关系词,限制性定语从句中不缺主语、宾语或表语,缺少地点状语,所以where 在此处引导定语从句并作地点状语,修饰先行词planet.A、C和D 三个选项都不能在从句中作状语.实际上是life has developed on the planet,但是在题目中没有on这个词,所以空格中应该填 on which=where.
点评 在考查定语从句的关系词,除了要弄清先行词,还要注意先行词和从句之间的逻辑关系.
