选项
A、pursuing
B、chasing
C、reaching
D、winning
答案
A
解析
此题考多义词pursue的词义及用法。pursue最基本的意义与chase相近,即“追逐,追赶,追捕”,但在题句中的意思却是have as an aim or purpose“追求",显然chase的设置目的是干扰考生选择,如果考生对pursue的“追求”一意不熟悉,那么就会在pursue和chase之间举棋不定,或认为“两个选择项似乎都可以时,哪个也不是正确答案”,而错选其他词。pursue作“追求”解时,是很常用的。如:pursue knowl—edge(truth,wealth,pleasure,learning)“追求知识(追求真理,追求财富,追求享乐,追求学问)”。一般按习惯不说win a goal或chase a goal。另外,从题句所用的时态分析,reach和win也都不合适,因为两者都表示终结意义“达到,赢得”,因此不能用(现在完成)进行时。题句意:“全世界的数十个科研小组一直在寻求如何利用太阳光分解水分子的既实际又经济的办法。”
