问题     The good news is that today’s teenagers are eager readers and prolific writers. The bad news is【C1】______they are reading and writing are text messages.
    According to a survey carried 【C2】______last year by Nielsen, Americans between the ages of 13 and 17 send and receive a(n)【C3】______of 3 ,339 texts per month. Teenage girls send and receive more than 4,000. It’s a【C4】_____ that can’t be neglected.【C5】______you don’t have teenage kids, you’ll see other people’s offspring being lazy around, eyes unfocused, tapping away,【C6】______to their surroundings. Take a group of teenagers to see the seven【C7】______of the world. They’ll be texting all the way. Seconds before the earth is hit by a gigantic planet or【C8】______by a super tsunami, millions of【C9】______ young fingers will be typing the human race’s last【C10】______words to itself.
    Now, before I am【C11】______ of throwing stones in a glass house, let me 【C12】______. I probably send about 50 emails a day, and I receive what seems like 200. But there’s a【C13】______. I also read books. It’s a weird old habit I 【C14】______as a kid, in the days before cell phones began nesting, bird-like, in the【C15】______ of the young. Half of today’s teenagers don’t read books-— 【C16】______ when they’re made to. According to the most recent survey 【C17】______the National Endowment for the Arts, the【C18】______ of Americans between the ages of 18 and 24 who read a book not【C19】______at school or at work is now 50. 7 percent, the【C20】______for any adult age group younger than 75 , and down from 59 percent 20 years ago.
【C3】
选项 A、mean
B、evenness
C、average
D、equal
答案C
解析 名词辨析题。根据第2题对句意的分析可知，这里指的是每月的平均量。[C]average用于指平均数时，多指的是长期以来形成的结果，且多为概数，故[C]average为答案。[A]mean用于指平均值时，指的是几个数字相加后除以数字的个数所得的结果，多用于运算中，例如：The mean of 3，4，5 is 4．[B]evenness“平均，均匀性”，多用来指分配时的平均性。[D]equal作名词指“同样的人，相等的数量，能与之比拟的东西，匹敌者”。
