How do you get a good night’s sleep?
You may put your pillow (枕头) at the proper height, drink a glass of hot milk or maybe listen to some light music before bedtime. 1. When World Sleeping Day falls on March 21, it will be a good time to explore a long-ignored fact that may make you feel tired after you wake up. Scientists have discovered that the position of your spine (脊椎) is very important when you sleep.
2. Let’s have a look at the advantages and disadvantages of each position.
On your back
Sleeping on your back is the ideal (理想的) position to be in. First of all, your spine is in the best position. 3. The downside is the greater likelihood of snoring (打鼾) and sleep apnea (窒息).
Lying on belly
4. Dr Vaclav Vojta, a US child development specialist, said this is bad for your back because it takes away the natural curve (曲线) of your lumbar (腰部的) spine. But he also noted that this helps to prevent some snoring and sleep apnea.
On your side
Sleeping on our sides happened naturally while we were in the womb (子宫). 5. Plus, sleeping on your side (the left side in particular) has been reported to reduce troublesome digestive problems like heartburn. The downside is the “dead arm” and finger numbness (麻木) from this position.
A. Lying face down with your legs straight and your arms right by your sides is a bad idea.
B. Sleeping on your side can be a quick fix for snoring and can help to improve breathing.
C. Do you and your friends ever talk about your sleeping position with each other?
D. And a new study suggests that the sleeping position has something to do with it.
E. Of the three sleeping positions, which one do you usually go for?
F. You are also less likely to have digestive (消化的) problems.
G. But one thing you may tend to ignore is sleeping positions.
The defeat of Lee Sedol, the world’s strongest Go (围棋) player, by a Google artificial intelligence (AI) program, looks like another milestone towards a world where computers can do almost anything a human can. It is not. There are uncountable things that only a human can do, and that no computer seems close to. The problem is that the purely human things are not economically useful to anyone. The things that computers can be taught to do are by contrast economically fantastic. But even the most powerful programs are not human, just as a shovel (铲车). They have no feelings. What they have is power, but this power is growing at a rate that should frighten us all.
It might be less frightening if computers were truly intelligent, but even the most powerful networks are less human than monstrous Martians (火星人). Their power will be used to make money for the firms that finance their development, and then for others quick and clever enough to take advantage of the new world. It is far more likely that they will increase inequality and still further remove the middle classes as we move towards an hourglass (以金钱来衡量的) society in which everyone is either very rich or very poor and likely indebted.
One of the ill effects of the spread of more intelligent computer networks is, at the same time, the spread of what might be called artificial stupidity. If AI is employed largely to replace unskilled labour, it is most productive when labour is kept unskilled or redefined that way. So much of the work in service industries is now simplified until it might be automated (自动化). And robots will never need pensions(养老金). AI is slowly reducing skilled work, like some forms of medical diagnosis (诊断), at the same time, as older doctors complain that the traditional human skills of diagnosis are falling out of medical training. The belief that everything worthwhile can be measured and then managed is far more damaging to humanity than the threat of artificial intelligence on its own.
But no victory in complicated Go games can bring us closer to truly human-like computers.
1.By mentioning the defeat of Lee Sedol, the author intends to tell us that ______.
A. computers can completely replace humans in everything
B. humans are of no practical economic values to the society
C. the power of computers is growing at a frightening rate
D. AI programs can not compare with humans economically
2.We can learn from Paragraph 2 that the power of computers will ______.
A. improve the quality of human life
B. widen the gap between the rich and the poor
C. make contributions to human development
D. promote equality at work places
3.What is the author’s attitude towards the future of artificial intelligence?
A. Optimistic. B. Supportive.
C. Cautious. D. doubtful.
Ireland has had a very difficult history. The problems started in the 16th century when English rulers tried to conquer (征服) Ireland. For hundreds of years, the Irish people fought against the English. Finally, in 1921, the British government was forced to give independence to the south of Ireland. The result is that today there are two "Irelands". Northern Ireland, in the north, is part of the United Kingdom. The Republic of Ireland, in the south, is an independent country.
In the 1840s, the main crop, potatoes, was affected by disease and about 750,000 people died of hunger. This, and a shortage (短缺) of work, forced many people to leave Ireland and live in the USA, the UK, Australia and Canada. As a result of these problems, the population fell from 8.2 million in 1841 to 6.6 million in 1851.
For many years, the majority of Irish people earned their living as farmers. Today, many people still work on the land but more and more people are moving to the cities to work in factories and offices. Life in the cities is very different from life in the countryside, where things move at a quieter and slower pace.
The Irish are famous for being warm-hearted and friendly. Oscar Wilde, a famous Irish writer, once said that the Irish were “the greatest talkers since the Greeks”. Since independence, Ireland has revived (复兴) its own culture of music, language, literature and singing. Different areas have different styles of old Irish songs which are sung without instruments. Other kinds of Irish music use many different instruments such as the violin, whistles, etc.
1.What does the author tell us in paragraph 1?
A. how the Irish fought against the English.

D. the independence of Ireland
Astronauts on shorter shuttle missions often work very long days. Tasks are scheduled so tightly that break times are often used to finish the day’s work. This type of schedule is far too demanding for long missions on the International Space Station(ISS). ISS crew members usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, Internet phone and through private video conferences.
While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crew member put together a collection of family photos, massages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth. During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. And as from early 2010, the Internet became available on the ISS, giving astronauts the chance to do some “web surfing” in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.
Many astronauts say that one of the most relaxing things to do in space is to look out of the window and stare at the universe and the Earth. Both the shuttle and the ISS circle the planet several times each day, and every moment offers a new view of the Earth’s vast mass and oceans.
1.What does the word “mimic”in Paragraph 1 probably mean?
A. find B. copy C. change D. lose
2.Which of the following best describes the families of the astronauts on the ISS?
A. They are excited and curious.
B. They are impatient and annoyed
C. They are worried and upset.
D. They are caring and thoughtful

A. get more pleasure in space than on the Earth
B. find living in space a bit boring and tiring
C. love to see the Earth from space
D. regard space life as common
4.The passage mainly discusses how astronauts __________.
A. spend their free time in space
B. observe the Earth from space
C. connect with people on the Earth
D. work for longer missions in space
Through the following four cultural relics, the world has known about Korea’s cultural treasures.
Pulguksa Temple
Pulguksa Temple plays an important part in the history of Korean temples. The building of Pulguksa Temple began in 751. In the year 774 the large temple was finished, becoming an important center for Korean national-protection Buddhism(佛教). The way used to create the store structure gave the temple a look of beauty.
