  【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(教学案例试卷课件教案)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。

  "Good morning," she said, copying her mother's voice. "早上好",她模仿着妈妈的声音说。

  4.He marked all the bees that came to the nearby feeding place blue, and all the bees that went to the faraway place were marked red. 他给所有来到近的喂食处的蜜蜂标上蓝色,给飞到远的喂食处的蜜蜂标上红色。

  faraway(远方的)是由 far + away构成的合成形容词。 nearby(附近的)是由 near + by构成的合成形容词。它们在句中都作定语。如:

  a faraway forest(远处的森林),faraway times(遥远的时代);a nearby hotel(附近的一家旅店),nearby hills(附近的小山)。

  注意:faraway在作定语时通常都连写,作表语或作状语时则分写(far away)。如:

  The house is not far away. 那座房子并不远。

  He lives far away from the school. 他住得离学校很远。

  nearby既可作定语,又可作状语;既可以连写(nearby),也可以分写(near by),还可以加连字符(near-by)。例如:

  I saw her going to a near-by post-box before lunch.

  我看到她午饭前去附近的信箱投信。

  They live nearby----less than a kilometre. 他们住在附近,不到一公里。

  He gave up his seat to the old man standing near by.

  他把座位让给站在附近的老人了。

  下面是我们学过的合成形容词:

  good-looking  好看的

  hard-working   勤劳的

  leftover     剩余的,残留的

  low-lying    地势低的

  nationwide    全国性的

  noble-minded  高尚的

  radioactive   放射性的

  well-known    闻名的

  widespread   广泛流传的

  worldwide    世界范围的

  5.They discovered that the farther away the feeding station was, the slower the dance was. 他们发现,喂食处越远,舞蹈动作的速度就越慢。

  "the+比较级……,the+ 比较级……"的意思是:"越……,就越……"。例如:

  The more he gives his children, the more they wan
