Unit 12 Section B教材全解

1.flew a kite放风筝

【重点注释】flew为fly的过去式,fly此处作及物动词,意为“放飞(风筝、飞机模型等)”,fly a kite=fly kites放风筝。例如:Can you fly a kite?你能放风筝吗?We flew kites in the park last Sunday.上个星期天我们在公园里放风筝了。My father helped me to fly the model plane.我的父亲帮助我放飞飞机模型。 【拓展记忆】fly还可作不及物动词:1)意为“飞,飞行”,fly to sw.=go to sw.by plane/air=take a plane to sw.乘飞机去某地。例如:I wanted to fly like a bird.我想象鸟一样飞。We flew to Beijing yesterday.昨天我们乘飞机去的北京。He flew back to London.他飞回了伦敦。Mr. Li flew to Shanghai.=Mr.Li went to Shanghai by plane/air.=Mr.Li took a plane to Shanghai.李先生乘飞机去上海了。2)意为“飞逝”。例如:How times flies!时间过得真快呀! 2.swam in a swimming pool 在游泳池里游泳

【重点注释】swam为动词swim的过去式;swimming是动词swim的动名词形式,在此用作定语,表示用途或功能,即a swimming pool=a pool for swimming。类似的表达还有:a sitting room起居室,a reading room阅览室,a waiting room候车室。

3.Did you do anything interesting last weekend?上个周末你做什么有趣的事情了吗?

【重点注释】★anything意为“任何事情”,它是不定代词,常用于否定句或疑问句中。例如:He didn’t do anything this morning.今天早上他没做任何事情。★anything interesting意为“有趣的事;任何有趣的事情”,形容词interesting修饰不定代词anything应后置,在句中作后置定语(即形容词应位于不定代词之后)。【语法】当形容词修饰something/anything/nothing等不定代词时,形容词要位于不定代词之后。例如:He told us something interesting.他告诉了我们一些有趣的事。This isn’t anything important.这并不是什么重要的东西。Is there anything interesting in today’s newspaper?今天的报纸上有什么有趣的事情吗?

【拓展记忆】1)不定代词something一般用于肯定句中;anything一般用于否定句、疑问句和条件状语从句中;nothing表示否定含义,构成否定句。例如:I have something to tell you.→I don’t have anything to tell you./I have nothing to tell you.→Do you have anything to tell me?(Do you have nothing to tell me?) If you want anything,call me.如果你想要任何东西,给我打电话。2)something可用于提建议或请求的问句中,以及希望说话对方作出肯定回答的问句中。例如:Would you like something to eat?你想要吃的东西吗?3)不定代词在句中作主语时,谓语动词一般用单数形式。例如:Nothing can make me cry.什么也不能使我哭。

something,anything与nothing

观察下面四个例句,思考something, anything和nothing的区别,然后补全“思考”和“结论”中所缺内容。

- 1 - / 8

A. The boy has something to tell you. 这个男孩有事要告诉你。 B. Is there anything interesting in today’s newspaper?

今天报纸上有什么有趣的东西吗?

C. The teacher didn’t say anything in class.这位老师上课时什么也没说。 D. The teacher said nothing in class. 这位老师上课时什么也没说。 【思考】

A句是肯定句,用的是 ___________ ;B句是一般疑问句,C句是否定句, 两句用的是_______________;D句和C句是同义句,D句用的是nothing,此句表示否定意义。 (something; anything ) 【结论】

1. something多用在____________ 句中;anything多用在 ___________句或疑问句中。nothing意为“什么也没有”,是表示否定的不定代词,相当于_________。

2. ___________也可以用在表示请求、建议或期望得到肯定回答的句子中。例如: Would you like something to eat? 你想要点吃的吗?

3. 从B句中的anything interesting可以看出,当有形容词修饰这些不定代词时,形容词要位于不定代词___________ (填“之前”或“之后”)。

(1. 肯定;否定;not ... anything 2. something 3. 之后 )

【运用】

选用something, anything或nothing填空。

1. Lingling, come here, please. I have ____________ to tell you. 2. We looked around, and didn’t find ____________ .

3. ______________ is difficult if you put all your heart into it.

(1. something 2. anything 3. Nothing )

4.My sister finished high school two years ago.我姐姐(妹妹)两周前中学毕业了。 【重点注释】①小学:primary school,elementary school,grade school;中学: middle school(统称),junior high school(初中),senior high school(高中)。 ②★high形容词,意为“高级的;重要的”。例如:I knew him in high school.我在中学时代就认识他了。He is a high official.他是个高级官员。★high还可意为“高的”,强调物体高出地面的空间高度。例如:The table is two metres high.这张桌子两米高。The garden’s got very high walls.花园有很高的墙。The mountain is very high.这座山很高。★high还可作副词,主要修饰动词,意为“高地”。例如:He jumps high.他跳得高。

【试题链接】Mount Qomolangma,“the roof of the world”,is about 8844.43

metres .

A.tall B.high C.highly D.height

(tall指人或物的高,不能指山脉的高;high可指物体的高,尤其指山脉的高;highly副词,意为“高度地”;height名词,意为“高度”。答案:B) ③ago副词,以前,常用于“一段时间+ago”结构中,意为“……以前”,表示“现在以前的某个时间”,常用于一般过去时态,two days ago两天前,a month/year/week ago一个月/一年/一个周以前。例句:I visited my grandma three days ago.我三天前看望了我的奶奶。He left here five years ago.他五年前就离开这儿了。Two days ago I went to visit him.两天前我去拜访了他。【助记】ago的用法:立足现在往前算,ago出来挑重担。

- 2 - / 8

【辨析记忆】ago与before ago 副词 多用于时间段之后,不能单独使用,常与一般过去时态连用 后接时间点,谓语可用将来时、现在时 The train left ten minutes ago. 火车10分钟前离开了。 I’ll be back before 10 o’clock. Please come to school before 8:00 Don’t stand before me. Spring comes before summer. 春天先于夏天到来。 介词 before 连词 表示位置,意为“在……前面” 表示顺序,意为“比……先,在……之前” 引导时间状语从句,意为“在……He will come to see you before he 之前”,主句是一般将来时态时,leaves Beijing.他离开北京之前会来看从句用一般现在时 你。 5.First,we took a long bus ride to a lake in the countryside.首先,我们搭乘一辆长途公共汽车来到乡下的一个湖(边)。 【重点注释】ride此处是可数名词,意为“(乘车的)旅行,旅程”。 例如:He gave me a ride to the plaza.他让我搭车去市场。It’s only a 5-metre ride to the park by bus.乘坐公共汽车去公园仅需5分钟。It’s a twenty-minute train ride from here.从这里乘火车需要20分钟。 【拓展记忆】1)ride作名词时,常用短语:★go for a +交通工具+ride =go for a ride on/in+a/an/the+交通工具“开/骑/坐(乘)……兜风”。例如:We went for a car ride.=We went for a ride in the car.我们去开(坐)车兜风了。we went for a ride on the horseback. 我们骑马。Shall we go for a ride in the car?我们开车兜一会儿风好吗? Let's go for a ride on horseback.我们出去骑马兜兜风吧。★have/take a ride“兜风”,have/take a ride on/in+a/an/the+交通工具= have/take a +交通工具+ride “骑/坐(乘)……兜风”。 例如:I had a ride on a horse for an hour.我骑了一个小时的马。He often takes a ride when he is free.当他有空时,他经常去兜风。He took a ride on a bus in the city.=He took a bus ride in the city.他乘公共汽车在市里兜了一圈。2)ride还可作动词,意为“骑(马等);乘(车)”等。例如:Can you ride a bike?你会骑自行车吗?The boy is riding a horse.这个男孩正骑着马。He learned to ride a horse at the age of nine.他9岁时学会了骑马。

6.There we put up our tents and made a fire to keep us warm and cook food on.在那里,我们搭起帐篷,生火取暖并(在上面)做饭。

【重点注释】①此处put是put的过去式,与原形put一样。(【思考】该句的否定句怎么变化呢?)put up此处是“搭起(建)”,还可意为“举起;张贴;建造(起)”,put up a tent搭建帐篷,put up hands举起手,put down放下(take off取下),put off推迟/脱下(=take off脱下)。例如:Please put up your hand if you have any question.如果你有问题就请举手。Put down your guns and put up your hands.把枪放下,举起手来。The teacher put up a map of China on the wall.老师在墙上挂起了一张中国地图。You’d better put up a notice here.你最好在这儿贴一张通知。We’re going to put up a building here.我们打算在这里盖一座楼。They put up many buildings last year.他们去年盖了许多楼。The meeting will be put off till next week.会议延期到下周。I put off my sweater after coming into the room . 我进屋后脱下毛线衫。

②make a fire意为“生火”,句中made是make的过去式。例如:He went back home and made a fire.他回到家里,生起了火。

- 3 - / 8

③keep us warm意为“使得我们暖和;保持我们暖和”,keep意思是“使……处于某种状态(情况)”,在这种情况下,keep常跟复合结构(“keep+宾语+宾语补足语” ),意为“保持……”,其中宾语补足语通常由形容词、副词、介词短语或现在分词等充当。例如:We should keep our classroom clean and tidy.我们应保持教室整洁干净。You’d better keep the child away from the fire.你最好让孩子离火远一点儿。The bad weather keeps us inside the house.坏天气使我们不能出门。Don’t keep me waiting for long.别让我等太久。He kept me waiting for an hour.他让我等了半个小时。

【拓展记忆】keep用作不及物动词,意为“保持、继续(处于某种状态)”,keep为连系动词。例如:Please keep quiet.请保持安静。We’re keeping in very good health.我们身体非常好。

④本句的主体部分是we put up tents and made a fire,其后的to keep us warm and cook food on表达的是made a fire的目的,即make a fire是为了取暖和做饭,动词不定式短语to keep us warm在句中作目的状语,表示目的(课本P.17:So these students go on a ropeway to cross the river to(go to)school.)。句末介词on后有所省略(on a fire),以避免重复。

【试题链接】We can make a fire the room warm so that you can chat for a while.

A.to keep B.keeping C.keep D.kept

(句意为:“我们可以生火来保持房间暖和,以便你们可以聊一会儿”。此处为动词不定式短语作目的状语。答案:A) 【拓展记忆】课本原句“…made a fire to keep us warm and cook food on.”=“…made a fire to keep us warm and to cook food on a fire.”,意思是:生火的目的是取暖和做饭,而做饭是在火上做。课本中to keep…和(to )cook…都是make a fire的目的,句中省略了to 和a fire,以避免重复。试分析下题:Why don’t you write?Sorry,I have no pen . A.to write B.to write on C.to write with (答案选C。 这是一个动词回头现象。意思是“我没有钢笔写字”,pen既做have的宾语又做write的宾语。用笔写是“write with the pen”,不能说成“write the pen”。在动词回头中省略掉第二个重复的宾语(the pen),所以选C。)【思考】为什么有的动词后加介词,有的不加介词呢?主要看to后的动词是否及物,不及物动词加名词前要先加一个介词(get to Beijing/arrive in Beijing/run to school/come to Rizhao……)。例如:I have a small room to live in.我有个小房间住。(注意有in) He is a pleasant fellow to work with . 他是个很好共事的人。(注意有in) I have a lot of things to do.(这个句子中不定式的动词do是及物的,不用加介词。)

7.On the first night,we just sat under the moon and told each other stories.在第一天晚上,我们就坐在月光下,互相讲故事。

【重点注释】①on the first night意为“在第一天晚上;在头一天夜里”,表示“在具体某一天的上午、下午或晚上” 等的特定时间,常用介词on,而只说“在夜里”是“at night”,在上午“in the morning”,在下午“in the afternoon”,在晚上“in the evening”。例如:On the evening of October 10th,she got a special gift.在10月10日的晚上,她得到了一件特别的礼物。 ②each other意为“互相;相互;彼此”,相当于one another。英语中each other为代词,在及物动词之后可直接用作宾语;而在不及物动词之后,则要借助介词。例如:They helped each other.他们互相帮助。We liked each other a lot.我们彼此都很喜欢对方。We help each other and learn from each other.我们互相帮助,互相学
