【重点难点讲解】

 1.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。

 …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…
 由it引导的强调句型是:
 It is/ was+ 被强调部分+ that-clause.

 例如:
 Mr Flower left all his money to his wife in 1989. 费劳尔先生于1989年把他的全部钱财留给了他的妻子。

 这是一个未经强调的句子。如果要将句中各部分加以强调,则可套用上述句型,分别构成下列强调句:
 It was  Mr Flower that left all his money to his wife in 1989. 是费劳尔先生于1989年将他的全部钱财留给了他的妻子。(强调是费劳尔先生留的,而不是别人)
 It was  all his money that Mr Flower left to his wife in 1989. 1989年费劳尔先生留给他妻子的是他的全部钱财。(强调留的是全部钱财,而不是其它东西)
 It was  to his wife that Mr Flower left all his money in 1989. 费劳尔先生是给她妻子于1989年留下了全部钱财。(强调留给了妻子,而不是其它人)
 It was  in 1989 that Mr Flower left all his money to his wife. 费劳尔先生是在1989年把全部钱财留给了他妻子。(强调是在1989年,而不是其它年份)

 2.In order to tell the bees apart, he painted some bees with little spots of colour. 为了便于区别,他在一些蜜蜂的身上点上颜色。
 tell apart是短语动词(v. + adv. ),作\"识别\"、\"辨别\"(to be able to recognize the difference  between two or more things or people)解。例如:
 Can you tell the two things apart? 这两件东西你能辨别吗?
 The twins are so much alike that their own mother can hardly tell them apart.
 这对双生子非常相像,他们的母亲都几乎难以辨认。

 3.They trooped behind the first dancer, copying its movements.
 它们成群结队地跟在第一只跳舞的蜜蜂后面,模仿它的动作。

 1)troop原作名词,作\"一队\"、\"一群\"解。例如:
 a troop of visitors(一群参观者)。
 它的复数形式(troops)作\"军队\"解。例如:
 We must have our own troops. 我们必须有自己的军队。
 但在课文中 troop作动词用,意思是\"结队而行\"、\"成群涌向\"(come or go together in a group)。用在句中时,句子的主语总是复数。例如:
 The children trooped into the park. 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。

 2)copy原作\"抄写\"、\"复写\"解。例如:
 He is busy copying  his composition. 他正忙着抄写他的作文
 本句中的copy引伸作\"模仿\"、\"仿效\"解。例如:
 Please copy my actions.(=Please act as I do. )请照我这样做。
