题目内容
The sunspot came into its active stage, __________ that happens once every eleven years.
A.one B.it C.the one D.what
【答案】
A
【解析】
试题分析:考查代词:句意:太阳黑子进入活跃时期,每隔十一年爆发一次的时期。这里的one="an" stage, 在句子中作同位语,表示什么样的一个阶段,不是特指的。It指代同类同物,The one特指可数名词单数,what引导从句。选A。
考点:考查代词用法
点评:代词的词义辨析考查的较为细致:One 指代可数名词单数,表示泛指;其特质形式为the one。It指代上文出现的同一事物;that指代可数名词单数,或者不可数名词,后面必须有定语修饰。起复数形式为those,同样后面也应该有定语修饰。
