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：文中兩處提及與other babies相處的好處，故B為答案。選項(xiàng)是時(shí)間狀語(yǔ)，可預(yù)測(cè)問(wèn)題是“當(dāng)嬰兒與誰(shuí)在一起時(shí)會(huì)……”。要注意記錄各種情況下嬰兒的表現(xiàn)，或者捕捉一種最特殊的情況。A、C都是在文中被否定了的情況；D項(xiàng)在文中并未談及。
33. What does Dr. Richard Perelman do?
[B]解析：文中只提到了一個(gè)具體人物Dr. Richard Perelman，隨后的定語(yǔ)從句中介紹他寫(xiě)了很多有關(guān)撫養(yǎng)孩子的書(shū)，故B為答案。
34. How do babies react to unfamiliar babies?
[B]解析：短文說(shuō)，babies看起來(lái)很怕陌生的成年人，但他們卻會(huì)試圖觸碰陌生的baby。所以B正確。
35. What is the best way to care for babies?
[A]解析：短文說(shuō)，如果這些研究成果是正確的話(huà)，可以增加family-oriented day care centers的使用，在那里孩子們可以有更多的時(shí)間和同齡人相處。所以A正確。
