选择题
It was Asimov was eleven years old his talent for writing became obvious.
A．that, when
B．When, which
C．when, when
D．when, that
答案
答案：D
题目分析：句意：当Asimov11岁时，就他的写作天赋就非常明显了。这里是强调句型，被强调的是when引导的时间状语从句，判断强调句型的方法是把It was that这三个词去掉，整个句子不缺成分，意思完整。故选D。
点评：本题难度适中。强调句型是高中阶段的重难点之一，也是高考的热点，需要考生有分析理解句子的结构的能力。尤其把强调句型与其他从句混合在一起考查更增加了试题的难度。
