Passage Three
Recently a five-year study was conducted by the Center for Childhood Development in Los Angeles, California, regarding the way babies react to different types of people. [32]The findings of the study suggest that infant children seem to be more comfortable around other babies than they are with strange adults.
The results confirm the ideas of [33]Dr. Richard Perelman, who has written many books about raising children. Dr. Perelman supports the findings of the study and adds that it is a sounder idea to keep children with other children, as in a day care center, than it is to have children cared for by a baby-sitter.
According to the results of the study, infants benefit from being in the company of other babies on a daily basis. [34]Whereas some babies seem to show fear of strange adults, they are likely to reach out to try to touch an unfamiliar baby. The study even suggests that children as young as one year old can form friendships.
Two of the children in the study were especially close. It was reported that if the children were separated for any reason they would start to cry. The only way to satisfy them was to allow them to be together. [35]If the findings are true it may lead to an increase in the use of family oriented day care centers where children can spend more time with each other and less time adults.

答案解析
32. According to the study, when do babies feel the most comfortable?
[B]解析：文中两处提及与other babies相处的好处，故B为答案。选项是时间状语，可预测问题是“当婴儿与谁在一起时会……”。要注意记录各种情况下婴儿的表现，或者捕捉一种最特殊的情况。A、C都是在文中被否定了的情况；D项在文中并未谈及。
33. What does Dr. Richard Perelman do?
[B]解析：文中只提到了一个具体人物Dr. Richard Perelman，随后的定语从句中介绍他写了很多有关抚养孩子的书，故B为答案。
34. How do babies react to unfamiliar babies?
[B]解析：短文说，babies看起来很怕陌生的成年人，但他们却会试图触碰陌生的baby。所以B正确。
35. What is the best way to care for babies?
[A]解析：短文说，如果这些研究成果是正确的话，可以增加family-oriented day care centers的使用，在那里孩子们可以有更多的时间和同龄人相处。所以A正确。
