The hole in the Earth's ozone layer (臭氧层) has until now protected Antarctica from the worst effects of global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3oC on average, with melting ice contributing to a global sea level increase of up to 1.4 metres.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much of the continent surface colder than usual.
But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3OC and a reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly. "Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctica has already resulted in a 10% rise in global sea level in recent decades.
Johnson believes that international action to reduce global warming is required immediately or it may be too late. "Everything is connected - Antarctica may be a long way away but it is an important part of the Earth's system," said Johnson. "It contains 90% of the world's ice, 70% of the world's fresh water and that is enough, if it melts completely, to raise sea levels by 63 metres."
Even in a worse-case situation scientists don't expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around 1.4 metres higher by the end of the century.
41. The underlined word "paradoxically" (in Paragraph 2) most probably means "__".
A. rapidly      B. approximately   C. contradictorily D. apparently
42. What is the effect of the hole in the ozone layer on Antarctica?
A. It is causing the ice to melt faster.
B. It is making much of the continent colder.
C. It is making the effects of global warming in the region worse.
D. It is reducing the amount of water in Antarctica.
43. What do scientists think is the biggest danger facing Antarctica?
A. Rising sea levels.             B. Warming sea water temperature.
C. Water pollution.                 D. Growing ice sheets.
44. Which of the following is true according to the passage?
A. Antarctica is currently experiencing the full effects of global warming.
B. The average temperature has increased by 3OC in recent decades.
C. Antarctica contains most of the world's fresh water.
D. Ten percent of Antarctica's ice has already been lost.
45. The best title for the passage is ______.
A. Our planet in danger                             B. Antarctica melting away
C. Action plan to save Antarctica         D. Let's save the ozone layer

A person, like a commodity(商品), needs packaging. But going too far is absolutely undesirable. A little exaggeration(夸张) will do no harm when it shows the person’s unique qualities to their advantages. To show personal attractiveness in a casual and natural way, it is important for one to have a clear knowledge of oneself. A skilled packager knows how to add art to nature without any signs of embellishment so that the person so packaged is not a commodity, but a human being, lively and lovely.
A young person, especially a female, shining with beauty and full of life, has all the favor granted. Youth however, comes and goes in a flash. Packaging for the middle-aged is primarily to hide the marks made by years. If you still enjoy life enough to keep self-confidence and work at pioneering work, you are unique in your natural qualities, and your attractiveness and grace will remain. Elderly people are beautiful if their river of life has been, through plains, mountains and jungles, running its course as it should. You have really lived your life, which now arrives at a self - satisfied stage of quietness and calmness with no interest in fame or wealth. There is no need to make use of hair dyeing. The snow-capped mountain itself is a beautiful scene of fairyland. Let your looks change from young to old in step with the natural ageing process so as to keep in harmony with nature, for harmony itself is beauty, while the other way round will only end in unpleasantness. To be in the company of the elderly is like reading a thick book of good edition, which attracts one so much that one is unwilling to part with it. As long as one finds where one stands, one knows how to package oneself, just as a commodity sets up its brand by the right packaging.
The underlined word in the first paragraph is closest to the word ______ in meaning.

A.decoration B.clarification C.movement D.identification

It can be concluded from the text that ______.

A.people should be packaged at all ages
B.people should be packaged in a special way
C.elderly people also care about packaging
D.proper packaging makes people attractive

For the middle-aged, attractiveness ______ .

A.hardly exists B.is the strongest
C.comes from the inside D.comes from the appearance

According to the author, if you want to keep in harmony with nature, you should ______.[源

A.dye your hair B.make up at a young age
C.follow the ageing process D.give up fame and wealth

The underlined sentence means that elderly people ______.

A.are usually packaged like a finely-made book
B.experience a lot and have rich knowledge of life
C.do a lot of traveling and can give you much information
D.enjoy reading thick books about beautiful nature and fairyland

Children who spend more time reading with their parents have a greater chance of becoming better readers than those who don’t. With help from their parents, children can learn techniques(技巧) to improve their reading skills.
“A lot of parents think after their child learns to read, they should stop reading to them,” Donna George said. “They are sadly mistaken.”
George offers her services to parents at the Title I Learning Centers. She said reading aloud to children may be the most valuable(有价值的) thing parents can do. “It is better for children to hear things at a higher level than where they are,” George said. “Parents are their child’s first teacher.” Parents help their children build listening, phonics(拼读法), comprehension(阅读理解) and vocabulary skills when they read aloud to them.
Before parents can identify reading problems, they should escape the enemy----television and limit the time their children spend watching television. George suggested not allowing kids to have a TV in their bedrooms, setting a schedule of when kids can watch or keeping a list of how many programs children watch. Louise Joiners said while her 14-year-old daughter and 10-year-old son enjoy reading, the television sometimes becomes a distraction. So she tries to build the situation by suggesting books the entire family will enjoy reading together, like the Harry Potter series.
Parents who do not read themselves should not depend on their children being enthusiastic about it. If parents would read to their children at least 15 minutes every day, children would not have so many problems in school. It is the parents’ job to help build that desire in their children, and of course to know what kind of books to read is also important.
The underlined word “distraction” means something that.

A.can improve children’s reading.
B.can make children interested
C.can make children not pay their attention
D.can help children’s right way of reading

In the fourth paragraphis the most important.

A.reading speed B.reading environment
C.reading skills D.reading materials

If the passage is not completed, what will be written after the passage?

A.What TV programs children can watch during reading.
B.Advice is given to control their children.
C.Parents choose reading materials for their children.
D.How children improve their reading by themselves.

Which one would be the best title for the passage?

A.Parents Are Their Child’s First Teacher.
B.How to Improve Children’s Reading Ability.
C.Children Spend More Time Reading with Parents.
D.How Parents Make Their Child a Better Reader.

Enough sleep is important to health. The amount of sleep needed depends on the age of the person and the conditions in which sleep takes place. The young may need more sleep than the old, but usually eight hours are enough for the health of grown-ups. Some can do with less than this amount, but others may need more. Every person knows his own need. It is then a matter of good judgment(判断) to satisfy his need. Sleep should always be enough to make one bring back his strength and get ready for a day’s work.
Fresh air is necessary to sound sleep. It is not without reason for some people to think that it is practicable to sleep in the open air. When one can keep himself warm, out-of-door sleeping probably gives the body its most complete relaxation(松弛).
Ability(能力) to sleep is largely a habit. The conditions referred to only lead to sleep. Out-of-door exercises, a good habit of regular hours and the avoidance(避免) of late eating and worry, which are largely within the control of any person, are all helpful to sound sleep.
A bath at bedtime, neither hot nor cool but of body temperature, may be helpful to sleep. Sleep-producing drug(药) should never be taken except when suggested by a doctor.
We know from the passageis enough for the health of a pupil.

A.equal or more than eight hours B.seven hours or so
C.Eight hours or so D.Less than eight hours

If you want to have a good sleep, is helpful.

A.forming the habit of taking sleep-producing drug.
B.keeping good habits.
C.staying up late night.
D.eating something at bedtime.

The amount of sleep a person probably needs has something to do with.

A.his character B.his control C.his age D.his habit

Before going to bed, you’d better not.

A.take a bath B.do any housework
C.go out for relaxation D.think a lot

Some people think that success is only for those with talent or those who grow up in the right family, and others believe that success mostly comes down to luck. I’m not going to say luck, talent, and circumstances(环境) don’t come into play because they do. Some people are born into the right family while others are born with great intelligence, and that’s just the reality of how life is.
However, to succeed in life, one first needs to set a goal and then gradually make it more practical. And, in addition to that, in order to get really good at something, one needs to spend at least 10,000 hours studying and practicing. To become great at certain things, it’ll require even more time, time that most people won’t put in.
This is a big reason why many successful people advise you to do something you love. If you don’t enjoy what you do, it is going to feel like unbearable(不可忍受的) pain and will likely make you quit(放弃) well before you ever become good at it.
When you see people exhibiting some great skills or having achieved great success, you know that they have put in a huge part of their life to get there at a huge cost. It’s sometimes easy to think they got lucky or they were born with some rare talent, but thinking that way does you no good, and there’s a huge chance that you’re wrong anyway.
Whatever you do, if you want to become great at it, you need to work day in and day out, almost to the point of addiction, and over a long period of time. If you’re not willing to put in the time and work, don’t expect to receive any rewards. Consistent(坚持不懈的), hard work won’t guarantee(保证) you the level of success you may want, but it will guarantee that you will become really good at whatever it is you put all that work into.
What can we learn from paragraph 1?

A.the meaning of success B.the reasons for success
C.the standards of success D.the importance of success

Paragraph 2 tells us.

A.how to succeed B.why to set a goal
C.how to get good at something D.how to practice

That successful people suggest doing what one loves is based on the fact that .

A.work makes one feel pain B.one tends to enjoy his work
C.it takes a lot of time to succeed D.one gives up his work easily

What is the main idea of the passage?

A.Having a goal is important to success.
B.Luck, talent and family help to achieve success.
C.Being good is different from being great.
D.One cannot succeed without time and practice.

You may not pay much attention to your daily elevator ride. Many of us use a lift several times during the day without really thinking about it. But Lee Gray, PhD of the University of North Carolina, US, has made it his business to examine this overlooked form of public transport. He is known as the “Elevator Guy”.
“The lift becomes this interesting social space where etiquette (礼仪) is sort of odd (奇怪的),” Gray told the BBC. “Elevators are socially very interesting but often very awkward (尴尬的) places.”
We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, lift users unthinkingly go through a set pattern of movements. He told the BBC what he had observed.
He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.
If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.
When a third person enters, you will unconsciously form a triangle(三角形). And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.
New entrants to the lift will need to size up the situation when the doors slide open and then act according to their decisions. Once in, for most people the rule is simple – look down, or look at your phone.
Why are we so awkward in lifts?
“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people, we have about an arm’s length of distance between us. And that’s not possible in most elevators.”
In such a small, enclosed space it becomes very important to act in a way that cannot be understood as threatening or odd. “The easiest way to do this is to avoid eye contact(接触) ,” she said.
According to Gray, when people enter an elevator, they usually _____.

A.turn around and greet one another
B.look around or examine their phone
C.try to keep a distance from other people
D.make eye contact with those in the elevator

Which of the following describes how people usually stand when there are at least two people in an elevator? (The point in the chart refers to one person.)

The underlined phrase “size up” in Paragraph 7 is closest in meaning to _____.

A.ignore B.judge C.put up with D.make the best of

According to the article, people feel awkward in lifts because of _____.

A.the lack of space
B.someone’s odd behaviors
C.their unfamiliarity with one another
D.their eye contact with one another
