Do you sleep well? Some people get off to sleep as soon as the head hits the pillow, but many others are not so lucky．In fact，the lack of quality sleep has become a public health issue around the world．According to the World Association of Sleep Medicine，45 percent of the world’s population suffer from sleep problems．One in eight people don’t sleep well and are easily woken．7．6 percent sleep less than 3 hours each night．Some even can not fall asleep for several days in a row．
As a basic bodily and mental need，sleep is essential for our survival．It helps us to fight diseases，strengthen our memory, perform better in work and school and improve our quality of life．Lack of sleep is known to have a significant negative influence on health，both in the short and long term．Poor sleep has been associated with obesity, weakened immune systems and even some cancers，as well as depression and anxiety．
The World Sleep Day, held on the third Friday of March，is an annual celebration of sleep to lighten the burden of sleep problems through better prevention and management of sleep disorders．
Unhealthy lifestyle may be the first to blame for sleeplessness．More and more people use cellphones and computers in bed，with many staying up until midnight．Modern technology does make our life convenient，but abuse of it ruins our health．Environmental conditions，such as temperature，noise，light，bed comfort also play an important role in one’s ability to get proper sleep．Besides，improper evening diet，like a full or an empty stomach，coffee and alcohol all contribute to sleep problems．Of course，when it comes to causing poor sleep stress from finances，family or work should never be ignored．
However, those who suffer from sleep disorders don’t necessarily have to continue to do so—most sleep problems can be solved．What can be inferred from Paragraph 1 ？

Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families. The early language had ________.
| A．a lot of problems | B．words and easy grammar |

The young boy saw me, or rather, he saw the car and quickly ran up to me, eager to sell his bunches of bananas and bags of peanuts. Though he appeared to be about twelve, he seemed to have already known the bitterness of life. “Bananas 300 naira. Peanuts 200 naira.” He said in a low voice. I bargained him down to 200 total for the fruit and nuts. When he agreed, I handed him a 500 naira bill. He didn’t have change, so I told him not to worry. He said thanks and smiled a row of perfect teeth.
When, two weeks later, I saw the boy again, I was more aware of my position in a society where it’s not that uncommon to see a little boy who should be in school standing on the corner selling fruit in the burning sun. My parents had raised me to be aware of the advantage we had been afforded and the responsibility it brought to us. I pulled over and rolled down my window. He had a bunch of bananas and a bag of peanuts ready. I waved them away. “What’s up?” I asked him. “I … I don’t have money to buy books for school.” I reached into my pocket and handed him two fresh 500 naira bills. “Will this help?” I asked. He looked around nervously before taking the money. One thousand naira was a lot of money to someone whose family probably made about 5,000 naira or less each year. “Thank you, sir,” he said．“Thank you very much!”
When driving home, I wondered if my little friend actually used the money for schoolbooks. What if he’s a swindler? And then I wondered why I did it. Did I do it to make myself feel better? Was I using him? Later, I realized that I didn’t know his name or the least bit about him, nor did I think to ask.
Over the next six months, I was busy working in a news agency in northern Nigeria. Sometime after I returned, I went out for a drive. When I was about to pull over, the boy suddenly appeared by my window with a big smile ready on his face.
“Oh, gosh! Long time.”
“Are you in school now?” I asked. He nodded. “That’s good,” I said. A silence fell as we looked at each other, and then I realized what he wanted. “Here,” I held out a 500 naira bill. “Take this.” He shook his head and stepped back as if hurt. “What’s wrong?” I asked. “It’s a gift.” He shook his head again and brought his hand from behind his back. His face shone with sweat. He dropped a bunch of bananas and a bag of peanuts in the front seat before he said, “I’ve been waiting to give these to you.”It can be inferred from the first paragraph that _________.

Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex.
In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent.
The study's participants were tested on science, maths, English and mechanical abilities.
Though there were twice as many men as women in the smartest group, there were also twice as many men among the bottom.
The aggregate（总数）scores of men and women were similar.
One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their homes.
"The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground.," the Daily Mail quoted Professor Bates, of Edinburgh University, as saying.
The research tallies with past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds.
It has been said that men are more ready to take risk when it comes to academics. Women have always found to be steadier in their learning.
A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds.
The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach.The purpose of the passage is to tell us that ________.
| A．man are smarter then women |
| B．man are more stupid the women |
| C．a new fact about the IQ of men and women has been found |
| D．men are more likely to receive first class university degrees |
According to Timothy Bates, less women are in the smartest group because _________.
| A．they are born stupid |
| B．they have to spend more time to tale care of their homes than men |
| C．they don’t like to take risk |
| D．they are not expected to be high achievers |
The underlined word tallies with in the eighth paragraph means________.
| A．agree with | B．deal with | C．go against | D．go with |
It can be inferred from the passage that_________.
| A．Women are steadier in their learning. |
| B．men are more ready to take risk in everything |
| C．women are securing more firsts and seconds |
| D．women are doing much better in academy |
Which of the following questions has NOT been discussed in the passage? _________.
| A．Why are men smarter than women? |

Not long ago the movie 2012 came into screen．The people were threatened by those scenes of destroying flood, severe earthquake, terrifying hurricane and constructions representing human civilization being destroyed and even swallowed by disaster．Luckily, they are just the director' s imagination, but the present situation is not heading a positive direction, either．
Take my own experience in Alaska as an example．Once I took a trip to the glacier．Along the way there stood signposts marking the snow lines of different years．They started from the foot of the mountain, but it was at the top that I finally saw melting glaciers（融化的冰川）．My heart ached seeing the beautiful blue ice melting at every second．
Sad but true, they are the effects of global warming and the result of our human impact．Furthermore, each year the rising sea level will kill 56 million people, and that' s about the population of the entire Italy．According to studies, if the temperature keeps on rising like this, by the year 2050, some islands and coastal cities including New York, Shanghai, Tokyo and Sydney will be drowned in water．
Our fortune is in our own hands．It depends on us to shape our future, to reduce future human impact and find ways to form a peaceful relationship with our environment. Therefore, it's time for actions to be taken right now．Contribute a little to energy saving by using more efficient light bulbs and less hot water．Let recycle become our habit by thinking twice before throwing something away．Let us take public transportation as our first choice when going to a certain place．It might cost more time for now, but it' s to the benefit of a permanent future．Take care of every tree and grass around us by watering them or simply just avoid destroying them．
In a word, small drops of water make a big ocean． The earth does not belong to us．On the contrary, we belong to the earth． Please bear in mind that the earth is our home．It is our responsibility to build a brighter and better future of our planet and prevent what happened in the movie 2012 from becoming reality．Why does the author talk about the movie 2012 in the passage ? __________.
