D
Grown－ups know that people and objects are solid.At the movies,we know that if we reach out to touch Tom Cruise,all we will feel is air.But does a baby have this understanding?
To see whether babies know objects are solid,T.Bower designed a method for projecting an optical illusion（视觉影像）of a hanging ball.His plan was to first give babies a real ball,one they could reach out and touch ,and then to show them the illusion.If they knew that objects are solid and they reached out for the illusion and found empty air,they could be expected to show surprise in their faces and movements.All the 16-to 24- week -old babies tested were surprised when they reached for the illusion and found that the ball was not there.
Grown－ups also have a sense of object permanence.We know that if we put a box in a room and lock the door,the box will still be there when we come back.But does a baby realize that a ball that rolls under a chair does not disappear and go to never-ne

答案

既然你在做这种题目,你的英文理解能力应该不会太低.而要解释这类答案,其中有一些就需要在你理解全文的基础上,才有可能.
例如,68的正确答案之所以是C,就是因为全文谈的就是“babies’ understanding of objects”这个主题,这是需要你读后归纳出来的.当然,其中一个可称为捷径的办法就是看一看每段的第一句,即英文所说的topical sentence.这里的三段的第一句分别为“Grown－ups know that people and objects are solid.”“Grown－ups also have a sense of object permanence.”和“babies develop a sense of object permanence when they are about 18 weeks old.”由此就可以断定主题与babies和objects有关.
69.的问题“object permanence”means that when out of sight,an object ________.答案当然是A.still exists .你只要根据原文的介绍,运用排除法和常识排除掉三个答案就行了.
70.同理,第三段里面的实验指提到使用的screen,当然就只能是B了.
71.同样运用排除法,既然A、B、C的陈述文中都没有提到,当然就只能是D了.
这四道题中,只有第一段难些,需要读通、读懂全文.这就需要长期实践和短期突击相结合了.
