11. The author uses the term "helicopter parents" to describe those parents_________.A、who usually travel by taking helicopters
B、who are often busy travelling on business
C、who frequently visit their children during holidays
D、who always interfere with the growing up oftheir children
【正确答案】：D
【题目解析】：细节判断题。题干问“helicopter parents”是哪一类父母。首先定位“helicopter parents”这个表达出现在第二段。这一段讲如何应对这类父母，提到parents… hovering over their children … and interfering with the maturation their children need。可见这类父母干涉子女成长。maturation是“成熟，成长”的意思，与选项D中的growing up同义，符合文章意思，故而答案为D。
