Question

Just like children, baby animals spend countless hours at play. After studying animal play for many years, scientists recognize that young animal play is practice for adult behavior. Today this play is roughly divided into the following groups.

Locomotor play refers to the movements animals carry out in their play. Running, leaping, turning, and kicking are some of the most common examples of locomotor play. An adult deer may run, leap, and twist(曲折前進(jìn)) to escape its attackers. Play movements like these surely make young animals nimble. Someday these skills might help save their lives.

Moving forward slowly, attacking suddenly .and biting are examples of predatory play that help young predators(食肉動物) prepare for a life of running after and taking hold of other animals. Wild cats, wolves, and bears are predators. It is very common to see these young animals play this kind of games which sharpen their skills and teach them about their strengths and limitations.

For children, playing with toys is both fun and educational. It helps improve their hand and eye movements as well as develop hand skills to accomplish tasks. It is the same with animals. Young chimpanzees improve their hand skills while playing with sticks. Birds also play with things in ways that teach. Swallows drop and recover feathers in mid air. Diving suddenly to catch the feathers is good practice for catching flying insects.

Social play helps animals learn how to behave when they run into other animals. And it teaches animals about communication. An animal gives signals to let another animal know it wants to play. Many animals give signals by showing a " play face" . In some ways this face is like a human smile; the animal holds its mouth in a relaxed and open manner. During play-fights, some animals may step backwards to signal that they are playing and not acting seriously.

Until now, scientists have understood playful acts help prepare animals for their serious adult situations. But the numbers of playful species and examples of animal play are vast. The purpose of animal play may have meanings scientists have not discovered yet.

【解析】

試題分析：本文主要通過對小動物和兒童的比較，揭示兩者都在玩耍和娛樂活動中學(xué)習(xí)和增強(qiáng)自己的各方面能力，以及社會活動對他們交際能力的提升等現(xiàn)象，這些都為他們長大后面對復(fù)雜的社會環(huán)境做了一定的準(zhǔn)備。

1. studying animal play for many years, scientists recognize that young animal play is practice for adult behavior. 可以推斷，其他三項(xiàng)不符題意，科學(xué)家們主要是要研究動物的行為舉止，故選D。

2. movements like these surely make young animals nimble. Someday these skills might help save their lives.根據(jù)句意可知運(yùn)動可以幫助動物保住性命，因此應(yīng)該是讓它們變得更加敏捷，更易逃脫，故選B。

3. forward slowly, attacking suddenly .and biting are examples of predatory play that help young predators(食肉動物) prepare for a life of running after and taking hold of other animals.可以判斷選項(xiàng)C是動物掠食性的舉動，故選C。

4. animal gives signals to let another animal know it wants to play. Many animals give signals by showing a " play face" .可知動物之間互相發(fā)送信號， 故選A。

5. this play is roughly divided into the following groups.的提示和全文內(nèi)容來看，作者采用的是總分總的結(jié)構(gòu)，并將動物幼崽和小孩子進(jìn)行了比較，故選B。
