When we say older people shrink,we don't...

When we say older people shrink,we don't mean they become tiny enough to fit in your pocket!We just mean that it's common for older people to become a little shorter over time.This kind of shrinking can't be stopped, although people can slow this process.But why does shrinking happen at all?

Because of gravity,cushions between the bones in the spine(脊骨)get compressed(压缩),which makes a person lose a little height and become shorter.

Another reason why some older people shrink is because of osteoporosis(骨质疏松).Osteoporosis occurs when bone is broken down and not enough new bone material is made.Over time,bone is said to be lost.Bones become smaller and weaker and can easily break if someone with osteoporosis is injured.

Older people—especially women,who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis.As years go by,a person with osteoporosis can get small breaks in bones that are called compression fractures.These breaks cause collapse of the spine and over time the person with osteoporosis can become hunched over(驼背).

Did you know that every day you shrink a little,too?You aren't as tall at the end of the day as you are at the beginning.That's because as the day goes on,water in the disks of the spine gets compressed due to gravity,making you just a tiny bit shorter.Don't worry,though.Once you get a good night's rest,your body recovers,and the next morning,you're standing tall again!

Smoking and drinking alcohol can make this problem worse.Want to do something right now to build strong bones?I believe what I say will help you.

1.What can we infer from the text?

A. For shrinking,people can do nothing about it.

B. If someone is injured,he will become shorter.

C. Women have smaller and lighter bones than men.

D. We aren't as tall at the end of the day as we are at the beginning.

2.What should we do if we don't want to shrink faster?

A. Reduce gravity.

B. Sleep as long as possible.

C. Be careful not to be hurt by others.

D. Keep away from smoking and drinking alcohol.

3.We can learn from the text about osteoporosis that______.

A. it makes people shorter

B. shorter people usually suffer it

C. women are more likely to develop it

D. once our bone is broken down,it will occur

4.What is the best title for the text?

A. Why do we shrink?

B. How to live a healthy life

C. How can we stop shrinking?

D. Some tips on how to keep healthy

 

1.D 2.D 3.A 4.A 【解析】本文主要阐述了人变矮的现象,分析了人变矮的原因,原来是因为我们的骨头发生了变化,如骨质疏松等。 1.细节理解题。根据文章倒数第二段第二句You aren’t as tall at the end of the day as you are at the beginning.可知人在早晨要比晚上要更高。故选D. 2.推理判断题。根据文章最后一段“Smoking and drinking alcohol can make this problem worse. Want to do something right now to build strong bones? I believe what I say will help you.”可知,抽烟和喝酒会让情况更严重,那么如果你不想变矮,那么你就不要抽烟和喝酒。故选D. 3.细节理解题。根据文章第三段第一句“Another reason why some older people shrink is because of osteoporosis (骨质疏松).”可知,骨质疏松也是人变矮的原因之一,也就是书如果一个人患了骨质疏松,那么他也可能变矮。故选D. 4.主旨大意题。根据文章主题段第一段最后一句But why does shrinking happen at all?可知,本文讲述的主要是为什么人会收缩,变矮?故选B. 【名师点睛】 每篇文章都会有一个主旨要义。主旨要义型题范围一般包括:短文标题、主题大意或段落大意等。此题型要求考生在理解文章后归纳文章要点,概括中心思想。考生需要分析文章的篇章结构,抓住文章的开头或结尾,从而找出能概括文章的主题句。主题句的特点:(1)语言特点:归纳性、概括性、抽象性;(2)位置特点:主题句常出现在“总结性”语言的“信号词”后,如:in summary, in a word, as a result, finally, in short, in conclusion和in brief等;主题句常出现在“转移话题式”语言的“信号词”后,如:but, however, nevertheless,Hence等。标题的语言特点:独特新颖 、概括性强、短小精炼。 A.主旨大意主要的设题方式有: (1)Which of the following best gives the main idea of this newspaper article? (2)The best headline for this newspaper article is ____. (3)What is the topic of the text? (4)The text is mainly about ______. (5)What's the main point the writer is trying to make in the last paragraph? (6)What would be the best title for the text? B.主旨大意主要的解题策略有: (1)标题类。文章标题可以是单词,短语,也可以是句子,它的特点是:短小精悍,多为一短语;涵盖性强,一般要求能覆盖全文,其确定的范围要恰当,既不能太大,也不能太小;精确性强,不能随意改变语言表意的程度及色彩。 (2)主旨类。概括主旨的方法是:先看首尾或各段开头再看全文找主题句,若无明显主题句,就通过关键词句来概括(如议论文中寻找表达作者观点态度的词句,记叙文寻找概括情节和中心的动词或反映人物特点的形容词)。文中出现两种或两种以上的不同观点时,务必牢记作者的观点才是体现全文中心的。此时,要注意一些转折词,如but, yet, however, although, in spite of, by contrast, on the contrary等。当文章中表示相反的观点时,往往用到这些词。答题时要弄清哪个是作者的观点,排除迷惑性信息,准确归纳主旨大意。 如小题4,根据题目要求,本题是标题类,需要短小精悍,涵盖性强。根据文章主题段第一段最后一句的疑问句可知本文讲述的主要是为什么人会收缩,变矮,从而得出答案。

My grandmother often said to me, “You can count the number of your true friends on the fingers of one hand.” For a long time I thought this was true. However, I’ve now discovered my grandmother was only half right. Maybe we do only make a few best friends in our lifetime, but those aren’t the only people that we can call friends. There are many different types. Let me tell you about a few of them.

One type of friends is the type I call the “football mom friend”. My neighbor Sally is a good example. We both have kids who play football in a football club, and someone has to take them to practice and pick them up. Sally and I and two other mothers take turns to do this. We meet sometimes and have tea and talk about what our kids are doing, but those are the only times that we meet each other. I enjoy being with these women, but we don’t do anything else together.

Another type is called the “hobby friend”. That’s the person you share an interest or a hobby with. Michael and Cater, who are brothers, are a good example of this type. We’re all in a bird watching club. Every few weekends the members of the club go on a trip to watch different kinds of birds. There’s nothing romantic about my relationship with Michael and Cater, of course. We just share interest in birds.

Then there’s the “other half of the couple” type of friends. Jim is married to Rose, a friend that I’ve known since college. When Rose married Jim, I realized that I would have to be Jim’s friend if I want to continue to be Rose’s. Jim and I don’t share so many interests, but we do have a friendly relationship.

1.What does the first paragraph tell us about?

A. We should make new friends.

B. We need true friends in our lifetime.

C. We must be friendly to all our friends.

D. We have rarely best friends in our lifetime.

2.Who is the writer’s true friend according to this passage?

A. Sally.    B. Rose.

C. Jim.    D. Michael.

3.What can we learn from the text?

A. The writer herself sometimes takes her kid to the football club.

B. Michael and Cater both fall in love with the writer.

C. Finally the writer agrees with her grandmother.

D. Sally and the writer are close friends.

4.From the last paragraph we learn that       .

A. the writer made friends with Jim only because of Rose

B. Jim was the writer’s good friend at college

C. Rose didn’t want the writer to be a friend of her husband

D. the writer made friends with Rose because of Jim

Have you thought about what determines the way we are as we grow up? Remember the TV program Seven Up! It started following the lives of a group of children in 1963. We first meet them as wide-eyed seven-year-olds and then catch up with them at seven-year intervals (间隔): nervous 14-year-olds, serious 21-year-olds, then grown-ups.

Some of the stories are inspiring, others sad, but what is interesting in almost all the cases is the way in which the children’s early hopes and dreams are shown in their future lives, for example, at seven, Tony is a lively child who says he wants to become a sportsman or a taxi driver. When he grows up, he goes on to do both. Nicki says, “I’d like to find out about the moon.” and goes on to become a space scientist. As a child, soft-spoken Bruce says he wants to help “poor children” and ends up teaching in India.

But if the lives of all the children had followed this pattern, the program would be far less interesting than it actually was. It was the children whose childhood did not prepare them for what was to come that made the program so inspiring. Where did their ideas come from about what they wanted to do when they grew up? Are children influenced by what their parents do, by what they see on television, or by what their teachers say? How great is the effect of a single important event? Many film directors, including Stephen Spielberg, say that an early visit to the cinema was the turning point in their lives. Dr Magaret Me Allister, who has done a lot of research in this area, thinks that the major influences are parents, friends and the wider society.

1.In the TV program Seven Up, we can meet       .

A. different groups of people at different periods of their lives

B. different groups of people at the same period of their lives

C. the same group of people at different periods of their lives

D. the same group of people at the same period of their lives

2.What are the examples in Paragraph 2 meant to show?

A. Many people’s childhood hopes are related to their future jobs.

B. There are many poor children in India who need help.

C. Children have different dreams about their future.

D. A lot of people are very sad in their childhood.

3.Spielberg’s words show that       .

A. going to a movie at an early age helps a child learn about society

B. a single childhood event may decide what one does as a grown-up

C. parents and friends can help a child grow up properly

D. films have more influence on a child than teachers do

Students today should do more reading. Indeed, the importance of reading can never be very stressed. First of all, reading, especial out-of-class reading, enrich our mind and broadens our horizons. Through reading, we learn what can’t be learnt in our classrooms. Beside, reading is also a way of relaxation. This is very refreshing to read a story before going to bed, or after a day of the study. There were many famous sayings about reading, like “Reading is to the mind that exercise is to the body”. Then how can we develop the habit of reading? In the first place, I believe we should start from an early age, then stick on it and never give up. Secondly, we should read what we are interested and also what is proper for us.
