Sherry Turkle, a professor of sociology at MIT, has for years been studying the way computers fit into people's lives.She points out that the computer, because it seems to us to be so intelligent,so capable, so...human, affects the way we think about ourselves and our ideas about what we are. She says that computers and computer toys already play an important role in children's efforts to develop an identity allowing them to test ideas about what is alive and what is not.
"The youngsters can form as many slight differences and textured relationship with the computers as they can with people."Turkle points out.
第一段She says that computers and computer toys already play an important role in children's efforts to develop an identity allowing them to test ideas about what is alive and what is not.这句话什么意思？怎么理解？identity这里是一道完形填空题目，A.identity B.personlity
C.habit D.trend 答案给的A,为什么选identity?B项D项为什么不对?

She says that computers and computer toys already play an important role in children's efforts to develop an identity allowing them to test ideas about what is alive and what is not.

翻译：她认为电脑和电脑玩具已经在发展孩童个体认知上起到了很重要的作用，使得他们体验到什么是生死。

这里B D选项是纯粹干扰项，就是为了把你引向歪路，以为这里谈的是“个性”“性格”，然后再去辨别他们之间的区别。其实这里取的是“identity”的“身份认同”这个意思。也就是“自我认同 ，自我认识”的意思。

你其实可以通过allowing them to test ideas about what is alive and what is not这个修饰identity的成分来判定，这里不是讲“性格”，而是讲“认知生死”，就能排除B D.
