Unit 4 Natural Disasters
Discovering Useful Structures
定语从句(Restrictive relative clauses)(Ⅰ)
that, which, who, whom, whose引导的定语从句
【情境探究】
观察上面对话, 并完成句子
1. The book __________ he bought yesterday is very interesting.
他昨天买的那本书很有趣。
2. Do you know the boy ____ just came in?
你认识那个刚刚进来的男孩吗?
that/which
who
3. He has moved into a house ______________ face the sea. ?

whose windows
【要义详析】
一、分类:
  定语从句可以分为限制性定语从句和非限制性定语从句。
1. 限制性定语从句
  它是先行词在意义上不可缺少的定语,如果去掉, 主句的意思就不完整或失去意义。这种从句与主句的关系十分密切,书写时不可用逗号分开。如果关系代词在限制性定语从句中作宾语, 关系代词通常可以省略。
*Shanghai is a city (that) I’ve always wanted to visit.
上海是我一直想参观的城市。
2. 非限制性定语从句
  它只是对先行词作附加补充说明,如果去掉,主句的意思仍然清楚、完整。这种从句与主句的关系不是很密切,书写时往往用逗号分开。非限制性定语从句不用that引导。
*The old woman, who lives on her own, has a cat for company.
这个老妇人一个人住,养了一只猫陪伴她。
二、关系代词的用法
定语从句的关系代词有that, which, who, whom以及whose。
*How do you like the film which/that was shown last Sunday?
你认为上周日上映的电影怎么样? (指物, 作主语)
*Do you know the gentleman who/that is sitting there?
你认识坐在那里的那位绅士吗? (指人, 作主语)
*The man (who /whom/that) you’re talking to is my friend.
和你谈话的那个人是我朋友。(指人, 作宾语)
*The palace (which/that) I often pay a visit to was built in the 17th century.
我经常去参观的那座宫殿建于17世纪。(指物,作宾语)
*Children whose diet is high in fat will gain weight quickly.
饮食富含高脂肪的孩子体重会增加很快。(指人,作定语)
【名师点津】whose还是which
  关系代词在定语从句中作定语时,无论指人还是指物,都要用whose,而不能用which。
*That’s the new machine whose parts are too small to be seen.
那是一台零件小到看不见的新机器。
*Have you seen the film Titanic, whose leading actor is world-famous?
你看过《泰坦尼克号》这部电影吗? 它的男主角是世界著名的。
【知识延伸】
关系代词的用法与分类依据
1.根据所引导的从句的限制性和非限制性;
2.根据所替代的先行词是指人还是指物;
3.根据它在从句中所充当的成分——主语、宾语或定语。
【即学活用】用定语从句合并句子。
(1)I live next door to a couple. Their children often make a lot of noise.

________________________________________________
________________________________________________
I live next door to a couple whose children often make a lot of noise. ?
(2)The man is from Peking University. I talked about the man at the meeting.

_____________________________________________

_____________________________________________

(3)The boy is sitting on the chair. The boy is my brother.

_______________________________________________

The boy who/that is sitting on the chair is my brother. ?
(4)The city is near the sea. The city is very beautiful.
_____________________________________________
The city which/that is near the sea is very beautiful. ?
三、关系代词that与which的用法辨析
1. 只用that而不用which 的情况
(1)先行词有形容词最高级修饰时
*Henry is the most energetic young man that I have ever come across.
亨利是我见过的最有活力的年轻人。
(2)先行词有序数词修饰时
*This is the third time that they have met.
这是他们第三次见面。
(3)先行词为all, much, few, little, everything, anything, nothing, none 等不定代词,或被不定代词修饰时
*Nothing that the teacher does doesn’t influence his students.
老师所做的事情没有不影响到他的学生的。
(4)先行词既有人又有物时
*He talked about the schools and teachers that he had visited.
他谈论了他拜访过的学校和老师。
(5)先行词前面有the very, the only, the last, the same等词修饰时
*This is the very room that I slept in that evening.
这正是我那天晚上睡觉的房间。
*This is the only thing that we can do now.
这是我们现在唯一能做的事情。
【名师点津】the same. . . that/as的区别:

the same. . . that表示“同一个”(同一性)

the same. . . as表示“类似的一个, 而不是同一个” (相似性)

*This is the same watch that I lost.
这就是我丢的那块手表。(同一个)
*I have bought the same watch as you have.
我买了一块和你一样的手表。(相似的,非同一个)
(6)关系代词在限制性定语从句中作表语时
*Our school is no longer the school that it used to be.
我们的学校不再是以前的样子了。
(7)句中其他位置已出现which,为避免重复,不用which而用that。
*Which is the car that has overtaken us?
超过我们的是哪辆车?
2.只用which 而不用that 的情况
(1)引导非限制性定语从句时
*I borrowed the book Sherlock Holmes from the library last week, which my classmates recommended to me.
我上周从图书馆借了《夏洛克·福尔摩斯》这本书,这是我的同学推荐给我的。
(2)在定语从句中, 关系代词前有介词时
*I was put in a position in which I had to accept I was less important.
我被置于不得不接受我不重要的境地。
【名师点津】强调句与定语从句的区别
*It was the student that/who asked the silly question.
就是这个学生问了这么一个愚蠢的问题。(强调句)
*He was the student who asked the silly question.
他就是那个问了愚蠢问题的学生。(定语从句)
【即学活用】选词填空(that/which)

文化知识习得
震级
震级是指地震的大小;是以地震仪测定的每次地震活动释放的能量多少来确定的。中国目前使用的震级标准,是国际上通用的里氏分级表,共分9个等级,在实际测量中,震级则是根据地震仪对地震波所作的记录计算出来的。地震愈大,震级的数字也愈大,震级每差一级,通过地震释放的能量约差32倍。
学习策略形成
1.听力技巧点拨
听力训练有非常多的形式:将听到的词或句子选出来、配对题、真假题、填充题、选择题、补全句子题、图表完成题。在听前,根据标题、图片、问题或选项可以预测听力材料的大体内容。
根据问题和选项进行预测是最常用的方法,一般的听力材料,大多数要求学生回答问题或选择正确答案,这些题目本身便为学生提供了可预测的内容。迅速浏览一下所提出的问题或问题中的选项,便能在听之前了解相当一部分信息。
2.清辅音与浊辅音的区别
英语辅音音素分清辅音与浊辅音,发音时声带不振动的是清辅音,如:/p/,/t/,/k/,/f/,/s/。发音时声带振动的是浊辅音,如:/b/,/d/,/ɡ/,/v/,/z/。
英语辅音大部分是成对的,分清浊两种。如:/p,b/,/t,d/,/k,ɡ/,/f,v/。英语中有一部分辅音是不成对的,如:/m/,/n/,/l/,/r/,/j/,/w/ 没有对应的清辅音,/h/ 没有对应的浊辅音。

THE NIGHT THE EARTH DIDN’T SLEEP
Strange things were happening in the countryside of northeastern Hebei. For several days,the water in the village wells rose and fell, rose and fell. There were deep cracks that appeared in the well walls. At least one well had some smelly gas coming out of it. Chickens and even pigs were too nervous to eat, and dogs refused to go inside buildings. Mice ran out of the fields looking for places to hide, and fish jumped out of the water. At about 3:00 am on 28 July 1976, bright lights were seen in the sky outside the city of Tangshan and loud noises were heard. But the city’s one million people were asleep as usual that night.

At 3: 42 am, everything began to shake. It seemed as if the world were coming to an end! Eleven kilometres directly below the city, one of the most deadly earthquakes of the 20th century had begun, a quake that even caused damage more than 150 kilometres away in Beijing. Nearly one third of the whole nation felt it! A huge crack, eight kilometres long and 30 metres wide, cut across houses, roads, and waterways. Hard hills of rock became rivers of dirt. In less than one minute, a large city lay in ruins. Two thirds of the people who lived there were dead or injured. Thousands of children were left without parents. The number of people who were killed or badly injured in the quake was more than 400, 000.
Everywhere survivors looked, there was nothing but ruins. Nearly everything in the city was destroyed. About 75 percent of the city’s factories and buildings, 90 percent of its homes, and all of its hospitals were gone. Bricks covered the ground like red autumn leaves, but no wind could blow them away.. Most bridges had fallen or were not safe to cross. The railway tracks were now useless pieces of metal. Tens of thousands of cows, hundreds of thousands of pigs, and millions of chickens were dead. Sand now filled the wells instead of water. People were in shock—and then, later that afternoon, another big quake shook Tangshan again. Even more buildings fell down. Water, food, and electricity were hard to get. People began to wonder how long the disaster would last.

[典例示范] 阅读下面短文,根据其内容写一篇60词左右的内容概要。
We’ve reached a strange—some would say unusual—point. While fighting world hunger continues to be the matter of vital importance according to a recent report from the World Health Organization(WHO), more people now die from being overweight than from being underweight. It’s the good life that’s more likely to kill us these days.
Worse,nearly 18 million children under the age of five around the world are estimated to be overweight. What’s going on?
[典例示范] 阅读下面短文,根据其内容写一篇60词左右的内容概要。
We really don’t have many excuses for our weight problems. The dangers of the problem have been drilled into us by public-health campaigns since 2001 and the message is getting through—up to a point.
In the 1970s, Finland, for example, had the highest rate of heart disease in the world and being overweight was its main cause. Not any more. A public-health campaign has greatly reduced the number of heart disease deaths by 80 percent over the past three decades.
Maybe that explains why the percentage of people in Finland taking diet pills doubled between 2001 and 2005, and doctors even offer surgery of removing fat inside and change the shape of the body. No wonder it ranks as the world’s most body-conscious country.
We know what we should be doing to lose weight—but actually doing it is another matter. By far the most popular excuse is not taking enough exercise. More than half of us admit we lack willpower.
Others blame good food. They say: it’s just too inviting and it makes them overeat. Some also blame their parents—their genes. But unfortunately, the parents are wronged because they’re normal in shape, or rather slim.
It’s a similar story around the world, although people are relatively unlikely to have tried to lose weight. Parents are eager to see their kids shape up. Do as I say—not as I do.
