John and Mary had a nice home and two lovely children. John had just been asked to go on a business trip to another city for several days and Mary would go with him too. They hired a reliable woman to care for their children and returned home a little earlier than they had planned.

As they drove into their hometown, they found a home on fire. After having a look, Mary said, “Oh well, it isn’t our fire. Let’s go home.” But John drove closer and said, “That home belongs to Fred Jones who wouldn’t be off work yet. Maybe there is something we could do.”

John noticed an old lady screamed to him, “The children! Get the children!” John grabbed (抓住) her by the shoulder saying, “Get a hold of yourself and tell us where the children are!” “In the basement,” cried the lady.

In spite of Mary’s disagreement, John soaked (浸湿) his clothes and ran to the basement which was full of smoke. He found the door and grabbed two children. As he left he could hear some more cry. He sent the two badly frightened children into the waiting room and asked how many more children were down there. The told him two more and Mary grabbed his arm and screamed, “John! Don’t go back! It’s dangerous! That house will fall down in any second!”

But he shook her off and went back. It seemed a very long time before he found both children and started back. As he climbed up the endless steps the thought went through his mind that there was something strangely familiar about the little bodies next to him, and at last when they came out into the sunlight and fresh air, he found that he had just rescued his

Before birth, babies can tell the difference between loud sounds and voices. They can even distinguish their mother’s voice from that of a female stranger. But when it comes to embryonic learning (胎 教), birds could rule the roost. As recently reported in The Auk: Ornithological Advances, some mother birds may teach their young to sing even before they hatch (孵化).

New-born chicks can then imitate their mom’s call within a few days of entering the world.

This educational method was first observed in 2012 by Sonia Kleindorfer, a biologist at Flinders University in South Australia, and her colleagues. Female Australian superb fairy wrens were found to repeat one sound over and over again while hatching their eggs. When

the eggs were hatched, the baby birds made the similar chirp to their mothers—a sound that served as their regular “feed me!” call.

To find out if the special quality was more widespread in birds, the researchers sought the red-backed fairy wren, another species of Australian songbird. First they collected sound data from 67 nests in four sites in Queensland before and after hatching. Then they identified begging calls by analyzing the order and number of notes. A computer analysis blindly compared calls produced by mothers and chicks, ranking them by similarity.

It turns out that baby red-backed fairy wrens also emerge chirping like their moms. And the more frequently mothers had called to their eggs, the more similar were the babies’ begging calls. In addition, the team set up a separate experiment that suggested that the baby birds that most closely imitated their mom’s voice were rewarded with the most food.

This observation hints that effective embryonic learning could signal neurological (神经系统的) strengths of children to parents. An evolutionary inference can then be drawn. “As a parent, do you invest in quality children, or do you invest in children that are in need?” Kleindorfer asks. “Our results suggest that they might be going for quality.” 5.The underlined phrase in Paragraph 1 means“ ”. A.be the worst C.be the as bad

B.be the best

D.be just as good

6.What are Kleindorfer’s findings based on?

A.Similarities between the calls of moms and chicks. B.The observation of fairy wrens across Australia. C.The data collected from Queensland’s locals. D.Controlled experiments on wrens and other birds.

7.Embryonic learning helps mother birds to identify the baby birds which . A.can receive quality signals

B.are in need of training D.make the loudest call

C.fit the environment better
