原文意思: 一个东西的数量是根据周围的温度决定的,而这个东西的数量是作为一个 thermometer。
题目分析: 原文有一个并列关系,就是这个东西的数量怎么样了并且怎么样了。A 在 and 后面用 they,但是语义上 they 应该指 number,可是 they 是复数,指代不了 number,A 干掉。B which指代应该是前面的 temperature(如果指前面的主语 number 根本没必要用,which,顺着说下来就可以, 只有serve的发起者和前面动词发起者不一样的时候才有必要加这个which) ,但是 which 如果指代 temperature 语义就不对了,应该是 number 作为 thermometer 而不是温度。干掉。C 用 in 是在某方面的意思,而那个 number 的升高和降低不是在吸引雌性这个方面的意思而是为了吸引雌性的意思,in 的意思不对,干掉(后面那个 serving 发起者应该是 number,在这个地方语义是正确的,所以我关注) 。D 用 to attract 表示目的并且用 and it,it 由于用了 and 显然于前面 number 保持一致,在语义上 it 指代 number 也没有什么错误,这个选项保留。E 用 serving,所犯的错误于 C 类似,干掉(如果后面的选项所犯错误与前面几个选项所犯错误类似, 没有必要关注这个选项的其它地方, 以最大火力攻击敌人最薄弱的地方是快速解决战斗的最好方法。 )
