Reading
The rest of its body is white.
the rest of表示“其余的……”,接单数可数名词its body作主语,指整体中的其余部分,此时谓语要用单数。
The beginning is great, but the rest of the movie is terrible.
开头很棒,不过这部影片的剩余部分很差。
知识归纳:the rest of的其它用法
“the rest of+复数名词/复数代词”指整体中的其余人或物。作主语时谓语要用复数。
Gina has gone to the library. The rest of the students are in the classroom.
吉娜去图书馆了。其余的学生都在教室里。
Some agree with Jim,but the rest of us agree with Sam.
有些人同意吉姆的意见,但是我们中其余的人同意桑姆的意见。
(2)“the rest of +不可数名词”指整体中的其余部分。作主语时谓语要用单数。
Only the eggs are good to eat. The rest of the food in the fridge has gone bad.
只有这些鸡蛋还可以吃,冰箱里剩余的食品都变质了。
知识拓展:the rest表示“其余”,作主语时要注意前面提到过的名词的单复数形式,由此决定谓语的形式。
Some of the information is from the Internet. The rest is from TV.
有些信息来自互联网,剩余的来自电视。
Some of his classmates are from Tianjin. The rest are from Beijing.
他班上有些同学是天津人,其余的是北京人。
Pandas in the wild usually eat bamboo.
in the wild意为“在野生环境中”,作后置定语修饰pandas。该短语中的the不能省,也不能换成a,还可作地点状语。
Do these vegetables grow in the wild or in the greenhouse
这些蔬菜是天然的,还是温室大棚的
(2)bamboo在此是不可数名词,意为“竹子”,是竹子的总称,没有单复数的变化。
There is some bamboo in the garden.花园有几棵竹子。
注意:如果表示竹子的种类,则bamboo是可数名词。
There are many kinds of bamboos in the garden.花园有很多种类的竹子。
3.In zoos,their menu includes bamboo, apples and carrots.
(1)include作及物动词,意为“包括”,可接名词、代词作宾语;接动词作宾语时动词要变为V-ing。
This plan includes most of your suggestions. 这项计划里包括了你们的大部分建议。
The tour includes visiting the Science Museum.旅游项目包括参观科学博物馆。
词语辨析:contain与include的区别
contain作“包括”讲时,其后的宾语与主语属不同类包含。
include作“包括”讲时,其后的宾语属于主语的一部分, 即同类包含。
The price includes postage. 价格里包含了邮费。
Sea water contains salt. 海水含有盐份。
知识拓展:include的派生词
1)including是介词,意为“包括”,其后可接表“人”或“事物”的词,放在句中作插入语,用逗号将其与前后内容隔开;也可作状语,多置于句末,用逗号将其与前面内容隔开。
Everybody in the village,including the old men and women,takes part in the spring planting.
村里每个人,包括老人和妇女,都参加了春种。
The book contains twenty maps,including three of Latin America.
这本书里有二十幅地图,包括三幅拉丁美洲地图。

4.A giant panda can eat as much as 30 kilograms of bamboo a day.
as much as表示“多达……”,用于表示量的比较。

知识拓展:as many as也表示“多达……”,用于表示数目的比较。
As many as 2 billion people will watch the opening of the Olympic Games on TV.
将有多达20亿人通过电视观看奥运会开幕式。
5.Pandas like to live on their own.
on their own用的是on one’s own短语,表示“独自地”。one’s要用形容词性物主代词,要与主语保持一致。该短语作方式状语,可与by oneself/alone互换(oneself要和主语保持一致)。
I can’t carry it on my own/by myself/alone. It’s too heavy!这我一个人搬不动。它太重了!
They need to eat a lot to stay healthy,so they spend more than 12 hours a day eating.
在so之前的分句中:
1)a lot作need to eat的宾语,相当于a lot of things。
We learn a lot from the movie.
我们从这部电影中学到了许多东西。(a lot = a lot of things)
to stay healthy是动词不定式作目的状语。stay在此作连系动词,意为“保持”,可与keep/remain互换。
The prices stay/remain/keep high.
物价居高不下。
so连接的结果分句中,spend more than 12 hours a day eating用的是“spend+时间+动名词”结构,表示“花费时间做某事”:
1)more than表示“多于”,可与over互换。
2)动名词eating前省略了介词in。
I spend more than/over two hours(in) reading this book.我花两个多小时读这本书。
知识回顾:spend表示“花费”时主语是人,还可构成下列结构
1)spend+时间/金钱+on sth表示“花费时间/金钱在某物上”。
I spent ten yuan on this book.我花了10元在这本书上。
He spends two hours on the housework.他花两小时在家务活上。
2)spend+金钱+(in)+动名词表示“花钱做某事”。
She spends some money dressing up.她花了很多钱在乔装打扮上。
7.it is not difficult for them to climb trees
这是“it is not+形容词+for sb+动词不定式”句型,表示“对...来说做.....不是......”。
(1)it是形式主语,真正的主语是动词不定式。difficult意为“难的”,是描述客观情况的形容词。
(2)for them是for引导的介词短语,此for引导的介词短语要和描述客观情况的形容词连用。不定式部分to climbs trees是them发出的动作,即for引出的短语作不定式的逻辑主语。
It is not difficult for us to finish the work. 对我们来说,完成这项工作不难。
8.They are strong enough to protect themselves.
句中用了“be+形容词+enough+动词不定式”结构,表示“足够......做某事”,不定式部分to protect themselves作程度状语。
He is rich enough to buy this new car.他足够富有,买得起这辆新车。
People are cutting down forests
这是现在进行时的肯定句,cutting down是及物动词短语cut down的现在分词结构(注意cut的现在分词要双写t)。
知识回顾:cut down是“及物动词+副词”类型的短语,意为“砍伐”,常接表示“森林;树木”等词汇作宾语。接名词时名词放在down前后均可;接代词时代词要放在down之前。
Don’t cut down forests.
=Don’t cut forests down.不要砍伐森林。
These trees are planted by us.Why do you cut them down?
这些树是我们种的。你为什么要砍伐它们。
It is cruel of them to do so.
这是“it is+形容词+of sb+动词不定式”句型,表示“做.....是......的”,使用该句型时:
it是形式主语,真正的主语是不定式部分to do so。cruel是形容词,意为“残忍的”,是描述主观感情的形容词。
of them是of引导的介词短语。该短语要和描述主观感情的形容词连用。不定式部分是由them发出的动作。即of引出的短语作该不定式的逻辑主语。do so替代前句中的“杀戮它们来获取皮毛”。
It is cruel of you to play with that cat.
你那样玩弄那只猫真是太残忍了。
语法点睛
1.句型It is+形容词+for sb+动词不定式和“It is+形容词+of sb to do sth”的异同点
相同点:
这两个句型中,it都是形式主语,指代动词不定式,这样可避免因为主语过长而造成的头重脚轻现象。
这两个句型中,动词不定式都是由介词短语中的sb发出的动作。这两个句型都表示“对...来说做...是...”。
It is important for students to learn English well.
对学生来说学好英语很重要。(it指代to learn English well,不定式是students发出的动作)
It is clever of him to leave that country.
对他来说离开那个国家是聪明之举。(it指to leave that country,不定式是him发出的动作)
(2)不同点:
It is+形容词+for sb to do sth中的形容词用于描述行为,用表示客观情况的形容词,诸如easy,difficult,hard,important,possible,impossible,necessary,interesting,great等。
It is+形容词+of sb to do sth中的形容词用于描述人,要用表示主观情况或态度的形容词,诸如good,bad,kind,nice, wise, clever,foolish,right,wrong,careful,careless,polite,impolite等。
of sb句型可以换为不定式作主语补足语的句子,但for sb句型不可以。
It is necessary for us to obey the laws.
对我们来说遵守法律很有必要。(important体现客观情况)
It is impolite of him to say so.
=He is impolite to say so.他这样说是不礼貌的。(impolite体现主观感情)
2.“be +(not)形容词+ enough +动词不定式”结构,表示“9不)足够...做某事”,be动词的形式由主语决定,形容词必须放在enough之前。动词不定式作程度状语。
The hall is big enough to hold 1000 persons.大厅足以容纳1000人。
Speaking
口语表达归纳:谈论义务时可用下列句型
(1)询问义务时可用句型“What should/must we do to......?”,表示“我们应该/必须做什么来...... ”。
(2)回答时可用We should/must......表示“我们必须......”(should/must后接动词原形);也可用We shouldn’t/mustn’t......表示“我们不应该/不准.....”。
(3)口语举例:以阻止河流被污染为例
—What should we do to stop the rivers from being polluted?我们应该做什么以阻止河流被污染?
—We mustn’t throw rubbish into rivers and we should also ask others not to throw rubbish into rivers.
我们要禁止往河里扔垃圾,而且我们也应该要求别人不要往河里扔垃圾。
More practice
1.Have you ever heard of the song“The story of the red-crowned crane”?
heard of在此是hear of的过去分词。hear of的用法如下:
它是“不及物动词+介词”类型的短语,可接表示“人;事物”的词作宾语,表示“表示间接听到或听说了某人某事”。
of可换成about。
I was shocked to hear of/about his poor death.
听到他惨遭不幸的噩耗, 我十分震惊。
I don’t know him, but I have heard about/of him.我不认识他,但我听说过他。
知识拓展:hear from sb表示“收到某人的来信、电子邮件等”。

自从丈夫离家以来,她还没有收到过他的书信。
2.Her father’s job was to look after red-crowned cranes.
was to look...cranes是动词不定式短语作表语,对主语Her father’s job 作解释说明。
The first task is to read the whole article.第一项任务是通读整篇文章。
She became good at raising them.
句中用了became good at+动名词结构,表示“变得善于做某事”,其中:

raising是及物动词raise的动名词,在此意为“饲养”。
I become good at swimming.我变得善于游泳。
They raise a flock of sheep.他们养着一群羊。
4.If a bird became sick,she took good care of it and stayed with it every day until it was strong enough to fly again.
这是含有条件状语从句、时间状语从句的主从复合句。
If a bird became sick是if引导的条件状语从句,其中:
1)if意为“如果”,置于主句前时要用逗号将其与主句隔开。此外,它引导的条件状语从句也可放在主句后,不用逗号将它们隔开;如果主句用一般将来时,从句应用一般现在时。
I will help you if I have time.如果我有时间我就帮你。
sick是形容词,意为“生病的”,在此作表语。

词语辨析:sick和ill表“生病的”的区别
1)sick是形容词,意为“生病的”,既可作表语,又可作定语。

2)ill意为“生病的”时通常作表语,作定语时意为“坏的”。

The actor often acts as an ill man in movies. 那个男演员在电影中常常扮演坏蛋。
she......fly again是主句。这个主句也是主从复合句,其中:
she took good care...day是该部分中的主句。它是肯定句,took good care和stayed是动词的过去式,是延续性动词。
until it...fly again是until引导的时间状语从句
知识归纳:until是till的强调形式,两者词义和词性相同,常可互换,用法如下
(1)until/till作介词时要接时间点,引导时间状语。
1)用于肯定句,谓语要用延续性动词或be动词,表示“直到...时为止”。
She was sick in bed until/till yesterday.她一直生病卧床休息到昨天为止。
Yesterday I worked on until/till midnight.昨天我一直工作到半夜。
2)用于否定句,谓语用短暂性动词,表示“直到...才...”。
She will not come until/till 12 o’clock.她要到12点才会来。
until/till作连词时引导时间状语从句。
1)主句是肯定句,主句谓语用延续性动词或be动词。until/till在此表示“直到...时为止”。

我们一直躲在灌木丛中,直到他们走过去。
2)主句为否定句,主句谓语用短暂性动词,构成“...not...until/till+从句”,表示“直到...才...”。

重要提示:until引导的介词短语和时间状语可以置于句首,till引导的内容不能放在句首。

2.one of the birds went missing

发烧消退了,但我仍然咳嗽。

while she was looking......bird是while引导的时间状语从句,其中:
while在此意为“当......时候”,引导时间状语从句置于主句前后均可,置于主句前时要用逗号将它们隔开;此时从句谓语要用延续性动词或be动词。
was looking for是过去进行时态结构,由“was+动词的现在分词”构成,表示look for这个动作在过去的时间里正在进行。

他们将建造一座纪念碑来纪念这位民族英雄。
Though Xiujuan died young,
Though Xiujuan died young是though引导的让步状语从句。though在此意为“虽然”。
妙辨异同:though和although作连词,意为“尽管”的异同点
相同点:
1)although和though都引导让步状语从句,它们都不能与but, however连用。
2)可与yet, still连用。
Although/Though he was old, yet he worked hard.
他虽然年老了,但工作仍然很努力。
Though/Although my father was tired, he still went on working.
虽然我爸爸很疲惫,但他仍然继续工作。
不同点:

Cultural corner
1.The World Wide Fund for Nature(WWF)was founded in 1961.

They found a castle on solid rock.他们在坚固的岩石上建筑了一座城堡。
He founded the Centre for Journalism Studies at University College Cardiff.
他在加的夫大学学院成立了新闻学研究中心。

用法辨析:连接副词where引导同位语从句和定语从句的异同点
相同点:都在从句中作地点状语。
不同点:
1)where引导定语从句时要修饰与它含义对应的先行词(即先行词表示地点),where等同于介词+which。
The city where/in which I live is very beautiful.我所居住的城市非常漂亮。
2)where引导同位语从句时,则没有与它们含义对应的先行词(即所修饰的词语不表示地点);它也不可转换为介词+which。
Then arose the question where we were to get so much money.
然后就产生了我们打算从哪儿挣这么多钱的问题。
in harmony with是固定短语,表示“与......和谐相处”。harmony在此作不可数名词,意为“和谐”。

科学家们仍致力于发明到达外层空间的新方法。
知识拓展:work on还可作“不及物动词+副词”类型的短语,意为“继续工作”,其后不接宾语。
