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.

Reading
Among the different types of bee, it is the honey bee that has most interested scientists because of the “language” they use to communicate with each other.
在不同种类的蜂中，最使科学家感兴趣的是蜜蜂，因为蜜蜂能用“语言”，来相互交际。
【点拨】…it is the honey bee that has most interested scientists…是一个由it 引导的强调句，被强调的部分是 the honey bee。如果不加以强调，则全句是：
…the honey bee has most interested scientists…
The development of the modern beehive in 1851 made it possible to design experiments to research the language of honey bees.
1851年新式蜂箱的研制，使设计实验研究蜜蜂的语言成为可能。
【点拨】 本句是一个简单句：The development… made it possible to design experiments …其中的 it是形式宾语，它所代替的真正宾语是后面的不定式短语 to design experiments。it作形式宾语的句型是：
主语 +及物动词 +it +宾语补足语 +不定式
e.g. I found it important to learn spoken English.
我发现学习英语口语很重要。

【点拨】amaze vt. 使惊愕；使大为惊讶：
e.g. He amazed everyone by passing his driving test.

有些漂亮或另类的东西，总能吸引许多眼球，就可以说是amazing things.

【点拨】＂．．．honey-bees communicate in their dark hives.＂是定语从句，其先行词
是＂ways＂，＂way＂后省略了引导词 “that”,也可用 “in which”，也可以省略引导词．
e.g. Some English words are not spelt the ways that they sound.
= Some English words are not spelt the ways in which they sound.
= Some English words are not spelt the ways they sound.
一些英语单词不是像他们发音那样去拼写．
He built a transparent wall, through which he could observe what went on inside.

在定语从句用法中介词+关系词是一个重点，介词后面的关系词不能省略，但是介词的后面不用that．
e.g.This is the house in which I lived two years ago.
某些在从句中充当时间，地点或原因状语的"介词+关系词"结构可以同关系副词when 和where 互换。

孩子们列队走进公园。 The game was over and the players trooped home.
比赛结束了，运动员整队回家。
Troop还有名词用法，作"一队"、"一群"解。 e.g. a troop of visitors (一群参观者)。 它的复数形式(troops)作"军队"解。 e.g. We must have our own troops.
我们必须有自己的军队。
【点拨】copy原作"抄写"、"复写"解。 e.g. He is busy copying his composition.
