Question

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

Answer 1

D

试题分析：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。
