The total energy given off is thousands of times more than any______chemical reaction could produce.
选项
A、compatible
B、conformable
C、comparable
D、conceivable
答案
C
解析
(1)句子结构。
主句是一个含有比较级的简单句:the total energy(主语),is(系动词),thousands of times more than…(主语补语)。
(2)选项词义。
A.compatible adj. 兼容的,相容的;和谐的;可以并存的
B.conformable adj.适合的,一致的
C.comparable adj.可比较的;比得上的
D.conceivable adj. 可想到的,可相信的,可想象的
本句大意为“释放的总能量是任何类似化学反应所能产生的能量的数千倍”。在比较句中,所对比的事物必须具有可比性,即具有相同或类似的性质、状态等。从四个选项来看,只有comparable具有“类似的,可比较的”的意思,因此,选项C最符合句意。
【知识拓展】(1)语法拓展:有关英语倍数的表达方式。
①表示“几倍大小(长短;数量)”,由“倍数+the size(length,amount…)”结构组成。
e.g.The earth is forty-nine times the size of the moon.
地球是月亮的49倍大。
②表示“……比……大几倍”,由“倍数+形容词(副词)比较级”结构组成。
e.g.Its profits are rising four times faster than the average company.
它的利润增长速度比一般公司快4倍。
③表示“……是……倍”,由“倍数+as+形容词+as…”结构组成。
e.g.Using his hybrid rice,farmers are producing harvests twice as large as before.
用他的杂交水稻种子,农民们种出的粮食比以前多一倍。
④用by+倍数,表示增加多少倍。
e.g.The production of grain has been increased by four times this year.
今年粮食产量增加了4倍。
