单选题 So involved with their computers ______ that leaders at summer computer camps often have to force them to break for sports and games.

A、 became the children
B、 become the children
C、 had the children become
D、 do the children become

【正确答案】 D

【答案解析】[试题分析] 此题测试倒装句的运用。 [详细解答] 当so，such用于句首加强语气时，要用倒装句。本题中so involved with their computers位于句首，说明孩子们对电脑非常着迷，句中的谓语动词become要部分倒装，由于是一般现在时，因此正确的倒装形式为do the children be come。
