背景知识
Do Animals Communicate?    When we think of communication, we normally think of using words-talking face-to-face, writing messages and so on. But in fact we communicate far more in other ways. Our eyes and facial expressions usually tell the truth even when our words do not. Then there are gestures, often unconscious: raising the eyebrows, rubbing the nose, shrugging the shoulders, tapping the fingers, nodding and shaking the head.
There is also the even more subtle "body-language" language “of posture: are you sitting-or standing-with arms or legs crossed? Is that person standing with hands in pockets, held in front of the body or hidden behind? Even the way we dress and the colures we wear communicate things to others. So, do animals communicate? Not in words, although a parrot might be trained to repeat words and phrases which it doesn’t understand. But, as we have learnt, there is more to communication than words.
Take dogs for example. They bare their teeth to warn, wag their tails to welcome and stand firm, with hair erect, to challenge. These signals are surely the equivalent of the human body language of facial expression, gesture and posture.    Colour can be an important means of communication for animals. Many birds and fish change colour, for example, to attract partners during the mating season. And mating itself is commonly preceded by a special dance in which both partners participate.
细说教材
Warming up

A small animal that helps the police get hold of thieves.
一种能帮助警察捉贼的动物。
【点拨】get hold of …= take/catch hold of …意思是“抓住…”；“获得…”
e.g. He took hold of the rope and pulled.
他抓住绳子用力拉。
I got hold of the sack and lifted it.
我抓住包，把它举了起来。
I need to get hold of some money quickly.
hold 还用作动词，意为“握住”“拥有”“容纳”“使…保持…”“持…观点”等
e.g. She was holding a book. 她手里拿着一本书。
They held their heads up.他们头抬得高高的。
She holds that the government’s policy is mistaken.
她认为政府的政策错了。
其常见短语搭配有：
hold a conversation/meeting 进行交谈/开会
hold the line = hold on 别挂电话
hold … back 阻止…
hold one’s breath 屏住呼吸
hold…off 使…与…保持距离
hold …over 使…延期

An animal that isn’t telling the truth.
一种会撒谎的动物。
【点拨】tell the truth“说实话”的意思，tell的相关类似短语有：
tell a/the lie = tell lies 撒谎
tell a story 讲故事
Listening

You are going to hear an interview with a woman who works in a zoo.
你将听到对一位在动物园工作的妇女的采访报道。

【点拨】interview 在这里是名词“采访”的意思，还有“面试”之意。
e.g. The film star agreed to give an interview after the wedding.
这位影星同意在婚礼后接受采访。
She’s got an interview for a new job.
她参加了新工作的面试。
interview 还有动词用法，是“采访”的意思,
要区别与cover的用法。interview 可以用interview sb. 或interview sth.
但cover不能用cover sb.只能说cover sth.
e.g. A reporter interviewed the prime minister.
一位记者采访了首相。
She’s being interviewed for the job.
她正在接受求职面试。
They sent a great many reporters to cover the conference.
【点拨】cover除了“采访”的意思外还有“用……遮盖；覆盖”“占有…（面积）;掩饰”
