第4题【单选题】
As Yale law professor Anne Alstott argues, justifying parental support depends on defining the family as a social good that, in some sense, society must pay for. In her book No Exit: What Parents Owe Their Children and What Society Owes Parents, she argues that parents are burdened in many ways in their lives: there is “no exit” when it comes to children. “Society expects—and needs—parents to pro
vide their children with continuity of care, meaning the intensive, intimate care that human beings need to develop their intellectual, emotional, and moral capabilities. And society expects—and needs—parents to persist in their role for 18 years, or longer if needed.”What is Professor Anne Alstott’s argument for parental support?
A、Good parenting benefits society.
B、The cost of raising children in the US has been growing.
C、The US should keep up with other developed countries.
D、Children need continuous care.

第6题【单选题】
I found in my baby’s behaviour a metaphor for the new generation. My wife and I had given him some books to examine，but he merely spit upon them. When we read to him，he did not feel comfortable. And so it is in the schools. We find that our students don’t read, that they look down upon reading and
scold those of us who teach it. All they want to do is watch TV. After this experience with the baby, however, I have reached a conclusion: let them watch it. If television is that much more attractive to children than books, why should we fight it? Let them watch it all they want!From the passage we know that the author is_____.
A、a doctor
B、an editor
C、a writer
D、a teacher
【正确答案】D
【答案解析】答案选D。根据本段第五句话的信息，我们会很容易地推断出作者是一位教师。这句话的原文是：We find that our students don’t read，that they look down upon reading and scold those of us who teach it. 它的意思是：我们发现我们的学生不读书，瞧不起读书，而且还骂我们这些教他们读书的人。由此来看，这里的“我们”指的就是当老师的这些人。
