标题 Why do you do that ?
章节 第五单元
关键词
内容
一、目地与要求:
掌握本单元出现的单词和词组。如:feed, fact, free, fetch, so that, grow up , in fact, be made from, in the past, in order to , wash away, break the rule, stop sb from doing, be covered with, so as to do…;
二、本单元知识重点与难点分析:
1.I\ll keep the box in the shade so that the sun doesn\t burn the little plants 我会把这个盒子放在阴凉地方,这样太阳就不会把幼苗晒枯。
本句中的so that 作“以便,为了,使能够”解,引导目地状语从句。
例如:He got up early so that he could catch the first bus.
他起床很早以便赶上头班车。
Please speak louder so that everyone can hear you.
请再大声点说,以便大家都能听到你说的话。
I\ll put some powder on the soil so that the little plants will grow better.
我会在土上加一些肥粉,以便使幼苗长的更好。
So that也可以引导结果状语从句,主句和从句是原因与结果的关系,作“因此”解,
例如:He often told lies, so that no one believed him.
他常常说谎,因此没有人相信他的话。
He turned up the radio, so that everyone heard the important news.
他把收音机的音量调大了,结果大家都听到这条重要新闻了。
He got up early this morning, so that he caught the first bus.
今天早上他起的很早,因此赶上了头班车。
注意:so that引导目的状语从句时,常用情态动词can, could ,may ,might , will , would和should。而在结果状语从句中,一般不用may, might, should等情态动词,so that前通常有逗号。
2.Then I\ll water them to stop the soil getting too dry.
然后,我将给这些幼苗浇水,以免土壤变得太干燥。
本句中stop sth/sb(from) doing sth 作“阻止……做某事”解。句中的“from”在口语中常可省略。类似的词组有“prevent sth/sb(from) doing sth/,“keep sb/sth from doing sth”.意思都是阻止某人做某事。但用keep sb from doing sth时不能省略from.例如:
The heavy rain stopped me (form) coming to attend the meeting yesterday.
昨天那场大雨使我没能来参加那个会议。
How can me stop the sun(from) burning the plants?
我们怎样才能使这些植物不被晒枯呢?
They did what they could to stop the soil from being washed away by water.
他们做了最大的努力,防止土壤被大水冲走。
You must prevent her (from) telling the truth.
你一定要阻止她说话出事实真相。
No one can keep the wheel of history going forward.
没有人能阻止历史的车轮前进。
3.Do you have to feed plants like you feed chickens?
你是必须像喂小鸡那样养育植物吗?
1)feed (fed, fed) vt.(give food to)喂,饲养。例如:
Have the pigs been fed yet?这些猪已经喂过了吗?
What do you feed your dog on? I feed my dog on meat .(=I feed meat to my dog.)
代用什么食物喂你的狗? 我用肉喂我那条狗。
feed…on sth=feed sth to…意思都是“用…来喂养…”但feed on sth的意思是“以…为食”。例如:Cattle feed chiefly on grass.牛主要以草为食。
2)…like you feed chickens.
本句中的like是连词,作“像,同…一样”解,这种用法是一种非正式的美国英语,在正式文体中,还是用“as”为好。
例如:Nobody loves you as/like I do, child.孩子,谁也没有像我这样疼爱你。
She can抰 cook well as her mother does.她烹妊的技术不像她母亲那样好。
4.Or do they grow up by themselves ?还是靠他们自己来生长?
(all) by oneself=alone=on one\s own.意思是“独自地,”例如:
He dare not go out at night(all) by himself.晚上,他不敢单独一人出去。
You must finish this experiment (all) by yourself.你必须独自地完成这个试验。
No one can finish this task on his own.没有人能独自一人完成这项任务。
5.It will make the cabbage plants grow big and strong.
它(肥粉)能使白菜秧长得又大又壮。
make sb/sth do sth使…做某事。make后跟不带to的不定式,作宾语补足语。例如:
The boss made them work for him without pay.老板迫使他们无偿为他工作。
They made me repeat the story.他们要我重新叙述了一遍那个故事。
上述例句如果改用被动语态来叙述,则不定式的符号to不能省略。例如:
They were made to work for him without pay.他们被迫为他无偿地劳动。
I was made to repeat the story.我被迫又重新叙述了一遍那个故事。
另:have sb do sth=get sb to do sth=let sb do sth都是“让某人做某事”的意思,没有make sb do sth的语气那样强烈。
6.Like me! 这是承上文来的一种省略的表达。意思是It will make the cabbage plants grow big and strong like me!它(肥粉)将使白菜秧长得像这样粗壮。
Like 在句中是介词,作“像…一样”解。后面跟名词或代词,构成介词短语,在句中作状语,例如:
I want to be a teacher like my father when I grow up.
长大后,我想像我父亲一样作一名教师。
Don\t talk to me like that!不要那样对我讲话。
We got on well with each other like old friends.我们之间相处融洽,就像老朋友一样。
7.What has changed in the past few years?.在过去的几年里发生了什么事?
in the past/last few years意思是“在过去的几年里”,句中时态通常用现在完成时。
例如:Great changes have taken place in China in the last ten years.
在过去的十年里(近十年来),中国发生了很大的变化。
The students have already read about twenty English novels in the past three years.学生们近三年来已经读了大约有二十本英文小说了。
注意:a few 几个,一些(表肯定),few没几个(表否定),但在句中的 the past few years的few之前,不能加a。不能说in the past a few years.这是一个固定搭配用法,在few前有past ,last , every等词时,few前就不能有a.例如:He went to see his father in the hospital every few days.每隔几天,他就到医院去看望他父亲一次。
8.A few of them can be cut each year for firewood. The rest are left to grow even taller.每年可以砍掉一些小树当柴火,其余的就留下来,让它们长得更高大。
1)a few of them相当于some of them,意思是“在…中有一些(人或物)”,表示肯定的意思。而few of them相当于almost none of them意思是“在……中没有几个(人或物)”,表示否定的意思。后面都跟复数的可数名词,例如:
I know a few of these people.这些人当中我认识几位。
I know few of these people.这些人当中没几个我认识的。
I met a few of my old friends there.我在那见到了几位老朋友。
I met few of my old friends there.我在那里没有见到几个老朋友。
the rest意思是“其余的;其它的”当它作主语时,谓语动词应视情况而定;它代替的是不可数名词要用动词单数形式,如代替的是可数名词的复数形式则应用动词的复数形式。例如:
I will take two and the rest are yours.我拿这两个,剩下的都是你的。
Take what you want and throw the rest away.把你所要的拿去,其余的切掉。www.cHinESejy.Com中国 教 育资源网
Pour me a glass of water and the rest is yours.给我倒一杯水,剩下的是你的。
About one third of the students in our class are from Beijing and the rest are from Shanghai and Tienjing.我们班大约三分之一的学生是北京人,其余的来自于上海和天津。9.People had to walk many kilometers in order to fetch wood.村民们为了砍柴要走很多公里的路程。
fetch的意思是“去取来”,“去把…拿来”,(go for and bring back sb/sth)接来(人),取来(物),
例如:Will you please fetch me a cup of tea?请你给我拿杯茶来好吗?You\d better fetch a doctor at once.你最好立刻去请一位医生来。Please fetch the children from school.请到学校去把孩子们接来。
Shall I fetch you your hat from the next room?要我去隔壁房间把你的帽子拿来吗?
注意bring, take, carry和fetch的不同含义。bring是“带来”;take是“拿去”、“带去”;carry是“携带”,既可是“带去”,也可是“带来”,没有方向性;fetch是“去拿来”,包含一去一来的意思。表示既去取又拿回的两上动作。例如:Please bring your dictionary here next time when you come to school.
请你下次来上学时,把字典带来。
Remember to take your school bag with you when you go to school.
记住去上学时,带着你的书包。
She never carries any money on her.她身上从不带钱。
Please fetch me some chalk from my office.请去办公室给我拿几支粉笔来。
10.Trees were cut but none were planted.(过去)只砍树不植树。
none是代词,作“一个也没有,没有一个”解。可以指人也可指物,作主语代替可数名词时;谓语动词既可用单数形式,也可用复数形式。但如果none代替不可数名词时,谓语动词只能用单数形式。例如:
None of them has(have) come back yet.他们当中还没有一个人回来 如果觉得高一英语第五单元Why do you do that ?-教学教案不错,可以推荐给好友哦。
