大全SECTION04-6

6.     Because young children do not organize
their attention or perceptions systematically, like adults, they may
notice and remember details that their elders ignore.

       (A)
like adults

       (B)
unlike an adult

       (C)
as adults

       (D)
as adults do（D）

       (E)
as an adult

       我想问的是，为什么不能选择A，我觉得如果D正确的话没道理说A错啊。谢谢

从句意考虑，本题考得是young children 和adult的区别是不是？young children 没有像adult那样去organize
their attention or perceptions systematically，所以，they may notice and remember details that their elders ignore.

如果，你用得A，young children like adults，也就是说young children 和 adults 都 do not organize their attention or perceptions systematically，结论怎么成立呢？（they may notice and remember details that their elders ignore）

供你参考。

拜天蝎MM所赐，这道题论坛上又很系统的解释，供你参考
