是A,因为有百分之九十的12至17岁的孩子用,这百分之九十中又有一半人天天用,可得答案A
另外,题目打错了一个单词哦~应该是Internet has become so popular
答案是A我看瞎了
是A
但原文中because打错了单词，应该是become
我认为应该选B，前面的90%只是说12到17岁用网络的，而下文与此无关把
你们都没错 因为你们都选了A...
这个还是看题的问题 一半的人对应的是90%的12~17岁的美国青少年 所以应该是0.9*0.5=0.45 多读几遍题目就好咧
应该是A
文章说的是在美国90%的12岁-17岁的孩子使用电脑 然后这些用电脑的孩子中有一半的天天使用
所以应该是90%中的一半 所以是45%
你们都没错
