After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.
Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (Although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement.
If you have trouble falling asleep, some people recommend breathing very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion the counting sheep will put you to sleep!
【小題1】A good title for this passage is ____.
| A．Sleep | B．Dreams | C．Good Health | D．Work and Rest |
| A．sick | B．asleep | C．stand up | D．a little sleepy |
| A．dream more often | B．have poor health | C．nervous | D．breathe quickly |
| A．your eyes move quickly | B．you dream | C．you are restless | D．both A and B |
| A．approximately six hours | B．around ten hours |
| C．about eight hours | D．not described here |
【小題1】A
【小題2】D
【小題3】B
【小題4】D
【小題5】D
解析試題分析：文章大意：本文講了睡眠的重要性及與其有關的幾個方面的問題，充足的睡眠能讓你恢復體力，讓第二天的你精力充沛。
【小題1】A主旨大意題。根據第一段并瀏覽全文不難看出本文的題目跟Sleep有關，而且sleep在每段都多次涉及，由此也可以得出本文的主旨就是sleep。所以答案很容易就選擇出A來。
【小題2】D 猜測詞義。 根據文章句子Other people believe that drinking warm milk will help make you drowsy. 不難翻譯出“有人認為喝牛奶會幫助人們drowsy”根據常識也知道牛奶可以催眠，但是并不能直接讓人睡著，所以B、asleep是指“睡著的”，D、a little sleepy 指“有點睡意”，這樣對比可以確定答案應該用D。
【小題3】B 推理題。文章開始就提到Sleep is necessary for good health.言外之意就是說，沒有充足的睡眠對身體不好，因此選B。其它選項文章都沒有提到。
【小題4】D 細節(jié)題。根據文章第三段when dreaming occurs, your eyeballs begin to move more quickly. This stage of sleep is called REM, which stands for rapid eye movement.可知，在所謂的REM階段，人是處于夢境中，而且眼球會快速轉動。所以綜合兩點選D。
【小題5】D 細節(jié)題。縱觀全文文章并沒有提到各個年齡階段的人們的最佳睡眠時間，所以答案為D。不能根據人們的常識來選擇C、八個鐘頭左右。要以文章為依據做出選擇。

Imagine going to sleep then waking up speaking another language. It may sound impossible， but it's actually happened.
The phenomenon(現象)of being able to suddenly speak another language is known as“Xenoglossia”， from the Greek words“xenos”(foreigner)and “glossa”(language)．
It once happened to a 13yearold girl from Croatia. After being unconscious(不省人事的)because of a disease for 24 hours in 2010，she woke up speaking fluent German. The girl， who came from the town of Knin in the south of Croatia，was studying German at school but she'd only started recently. Her parents said that she'd been reading German books and watching German TV at home， but that she wasn't fluent in the language.However ，since waking up， she's been able to communicate “perfectly”in German.What's really strange is that she's now unable to speak Croat，her mother language.Doctors at Split's KB Hospital have asked some experts to examine the girl as they try to find out what caused the change.Dr Mijo Milas said，“In earlier times this would have been considered as a miracle(奇跡)；we prefer to think that there must be an explanation—it's just that we haven't found it yet.”
In 2007，Matej Kus from Czech became unconscious after a motorbike accident. On waking up 45 minutes later，he could speak fluent English.Matej was only 18 years old at the time， and had just started studying the language and so was at a low level.Peter Waite，Kus's teammate said，“I couldn't believe what I was hearing.It was really clear English.It was unbelievable to hear him talk in unbroken English.”Unluckily，Matej's new language skills didn't last.Two days later， when he recovered fully from the accident， he'd completely forgotten his English.
We still don't know exactly what happened to the two people. Perhaps scientists will discover something new and exciting. But until then， keep studying!
【小題1】According to the passage，what is“Xenoglossia”？
| A．That someone becomes unconscious. |
| B．That someone speaks a new language in a sudden. |
| C．That someone doesn't like his mother language. |
| D．That someone is able to speak Greek suddenly. |
| A．Having accidents. |
| B．Speaking fluent German. |
| C．The phenomenon of Xenoglossia. |
| D．Being unable to speak. |
| A．wanted to know what caused her change |
| B．believed she had a talent for language |
| C．didn't study German for a long time |
| D．didn't like learning German |
| A．Matej Kus is now afraid of motorbike racing. |
| B．The girl from Croatia lost consciousness for several days. |
| C．The girl from Croatia was knocked unconscious in an accident. |
| D．Matej Kus could only speak a little English before the accident . |

Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people at your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!www.zxxk.com
You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles (粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes’ color or pattern.
You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.
It’s time to go to work. In 2025, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.
So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one example—what will be the next?
【小題1】We can learn from the text that in the future ________.
| A．people will never get old |

Cast your mind back to the past twenty years and hardly did anyone have their own email account. The Internet had just taken off in 1991 and people were only using office and PCbased email exchanges.
In the mid 1990s external email providers appeared. The most famous of these was Hotmail, the first free email provider and webbased email service. Sabeer Bhatia and Jack Smith launched Hotmail on July 4, 1996. And Microsoft took note of and bought Hotmail for $400 million on December 30, 1997, a nice birthday present for Bhatia who turned 29 that day. It was relaunched as MSN Hotmail and in 2007 was relaunched again as Windows Live Hotmail.
Fast forward the present day and most of us have at least a personal webbased email account. It seems impossible to live without them. One of the biggest advantages of email is the fact that communication has become so much easier, especially with those across different time zones. Email takes seconds to send a message whereas letters, as we used to communicate by, could take weeks. Of course there was the fax, that beeping invention from the 1980s, but it wasn’t as secure as email and you never knew if the person on the other end had picked up your fax or if it had got lost somewhere in the office.
In conclusion, one of the best inventions from the 1990s has to be email. But sometimes people are too closely connected to their email and have a compulsion to check it several times a day. At work, people have become lazy and instead of going to speak to the person sitting next to them, they send an email，causing an in box to pile up with more time spent reading email and responding rather than working. Clearly, an invention that saved time because of its quick and speedy connection can now also cause us to waste a lot of time.
【小題1】The earliest web-based email came into being probably _______.
| A．in 1991 | B．in 1996 | C．in 1997 | D．in 2007 |
| A．it is exactly as good as email |
| B．it is much better than email |
| C．it is less convenient than email |
| D．it is easier and faster than email |
| A．strong desire | B．common sense | C．special curiosity | D．general idea |
| A．We should check email boxes frequently. |
| B．Lazy people like sending an email. |
| C．Email brings us great convenience. |
| D．Good inventions also cause problems. |

My house is made out of wood, glass and stone. It is also made out of software.
If you come to visit, you’ll probably be surprised when you come in. Someone will give you an electronic PIN （個人身份號碼）to wear. This PIN tells the house who and where you are. The house uses this information to give you what you need. When it’s dark outside, the PIN turns on the lights nearest you, and then turns them off as you walk away from them. Music moves with you too. If the house knows your favorite music, it plays it. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.
Of course, you are also able to tell the house if you want something. There is a home control console (控制臺), a small machine that turns things on and off around you.
The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you my car keys, you can use my car. The car works for you because you have the keys. My house works for you because you wear the PIN or hold the console.
I believe that ten years from now, most new homes will have the systems that I’ve put in my house. The systems will probably be even bigger and better than the ones I’ve put in today.
I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, “How will I live without them?”
【小題1】What does the passage mainly discuss?
| A．How to develop a new system. | B．The function of the PIN. |
| C．A home for the future. | D．Easy life in the future. |
| A．To let readers know why his ideas are new. |
| B．To let readers know how special his house is. |
| C．To explain the importance of the PIN and the console. |
| D．To explain more easily what the functions of the PIN and the console are. |
| A．An IT expert. | B．A famous doctor. |
| C．An idealist | D．An experienced teacher. |

This winter, the air quality over the north China plain was so bad that it was actually off the standard scale. The air pollution reached levels that the World Health Organization describes as dangerous. On Thursday, heavy smog blanketed most of northern and eastern China again.
It is reasonable to ask why the air pollution is so bad this winter. Weather conditions and topographic(地形學的) factors have been given as reasons, but, although contributing factors, these are not to blame. The worsening air pollution is linked to an energy mix that relies heavily on coal and to motor vehicle emissions(排放). But despite the astonishing growth of motor vehicles in our cities, it is the burning of coal that is the biggest cause of air pollution. More than half of the country's power plants are located in the eastern region and China's coal consumption has more than doubled in the past decade, reaching 3.8 billion tons last year, accounting for almost half the world's total coal consumption. And with coal occupying nearly 70 percent of the country's primary energy consumption, it has become critical to reduce the use of coal if we are to solve the nation's overall air pollution problem.
In the face of the poisonous air recently, one citizen said, "we have nothing but hot air to purify the skies". In fact, the government plans to have 350 billion yuan ($55.67 billion) investment in improving coal-fired facilities and limiting the use of yellow-label cars that do not meet the Euro I emissions standard and so on.
However, it would be far more effective to reduce emissions at the source, which means that the biggest challenge currently facing government departments is saying "no" to the country's air polluting offenders. According to the Joint Prevention and Control Plan on Air Pollution in Key Regions released recently by the State Council, the amount of coal the nation consumes is set to rise by 30 percent during the period of the 12th Five-Year Plan. This is not going to let anyone breathe easier.
This highlights a key problem when it comes to environmental issues in this country - economic development comes first. The fundamental cause of the worsening air pollution is the idea of economic growth at any cost, which has resulted in ever-worsening pollution. And the priority(優(yōu)先權)given to economic growth presents another problem, namely the failure of existing environmental protection policies and regulations to control pollution. For instance, the current weak regulations covering emissions would suggest there has been a significant reduction in emissions when clearly this is not the case. Also those enterprises found breaking the regulations are still far lower than the cost of treating the pollution they produce. This means even if many large-scale enterprises with lagging production capacity(能力) fail to meet the requirements for environmental protection, the environmental protection department is incapable of shutting these enterprises down or forcing their relocation.
Dealing with air pollution requires taking action at the local level to reduce vehicle emissions and at the regional level to reduce industrial emissions. But it also requires giving more priority to environmental issues in policymaking. Our hope is that the environmental protection department will be truly capable of saying "no" to pollution, and it will raise standards and effectively enforce them, and that governments at all levels will prioritize quality of life not just economic growth.
【小題1】The writer mentions the heavy smog in parts of China in Paragraph1 in order to_____.
| A．remind people to stay in doors because of the bad air quality |
| B．show people’s concern about the priority to economic growth |
| C．introduce the issue about the serious air pollution |
| D．highlight the importance of government’s policies and regulations |
| A．Because enterprises are encouraged to develop economy at the cost of the environment. |
| B．Because much emphasis has been laid on economic growth regardless of the cost. |
| C．Because it’s impossible to relocate the enterprises for lack of money. |
| D．Because the production capacity of enterprises falls behind the required speed. |
| A．the sharp growth of coal consumption in recent years |
| B．the rapid increase of motor vehicles in cities |
| C．the building of power plants in northern China |
| D．the poor weather conditions caused by complex geographical factors |
| A．Giving priority to economic development in policymaking. |
| B．Making environment-friendly policies and carrying them out effectively. |
| C．Increasing investment in the construction of coal-fired facilities. |

The name sounds funny but the idea is no joke: it’s a personal toilet called the pee-pool, Anders Wilhelmson, a Swedish architect, is the inventor of the pee-pool.
He became interested in the idea of sanitation(衛(wèi)生設施) after taking part in a research project on the social and political development of cities, One of the most common problems he found in developing countries was the lack of toilets, He wanted to do something to help, So working with others, he started the project in 2005, and the next year started a company called Peepoolple.
The toilet is a single—use bag made of environmentally friendly plastics, The inside is treated with urea （尿素）, a chemical commonly used as fertilizer, The hotter the weather, the more quickly the waste turns into what is needed by plants The sanitation process can be as soon as a couple of hours or as long as two to four weeks ,You can just bury it in a pot and grow whatever you like.
The company expects to start selling the bags in August in Kenya and Bangladesh, But it is just beginning production and sales in Nairobi now , Full production could reach about half a million bags a day and people may be able to buy the pee-pool in countries Vietnam, Bangladesh, etc.
The United Nations says more than two and a half billion people around the world do not have good sanitation ,Many have no choice but to use the outdoors, which is not only bad for the environment ,but also harmful to people’s health, Each year, poor sanitation leads to three fifths of those people getting an infectious disease which on average causes one out of 1,000 patients to die.
Jack Smith ,the founder of the World Toilet Organization ,says “This is quite an unacceptable situation given the fact that we are living in the modem world , And strangely, many of them own televisions ,phones but have no toilet.”
【小題1】What was the original purpose of Anders Wilhelmson in starting the company?
| A．To protect the local environment |
| B．To earn a lot of money from the project |
| C．To do research on the social development |
| D．To help solve the problem of lack of toilets in developing countries |
| A．It can be used over again |
| B．Its sanitation process doesn’t last long |
| C．It works better in summer than in winter |
| D．It should be buried in a pot after being used |
| A．Nairobi | B．Vietnam | C．Sweden | D．Bangladesh |
| A．poor sanitation may cause many problems |
| B．many people don’t care for the environment |
| C．many people get ill from using the outdoors |

Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms.
Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago.
Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger.
"As new species of pests and diseases evolve and potentially the environment for them becomes more amenable at higher latitudes, the pressure on the breadbaskets of the world is going to increase."
Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species.
“It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America.”
Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.
【小題1】The purpose of Dan Bebber’s research was to find ______.
| A．if farmland could be moved to colder places thanks to global warming |
| B．if diseases and insects harmful to crops were going towards colder areas |
| C．if organisms were moving to the north and south poles |
| D．if the number of crop pests was increasing |
| A．it will be hard for farmers to kill them |
| B．the most productive farmland will produce more crops |
| C．the earth will not produce enough food to support the world |
| D．the conditions for some crops may be improved |
| A．Climate change helps crop pests to adapt to new environment. |
| B．Foreign species are brought in by trade. |
| C．Invasive species doing well in warmer places might do well in America. |
| D．The impacts of the climate and species changes on crops are not easy to determine. |
| A．agreeable | B．terrible | C．unfriendly | D．changeable |

Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.
Adaptable glasses
Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, “Can I invent a pair of glasses that could be changed by the wearer?” He designed two plastic lenses（透鏡）that are filled with a special liquid. Using syringes（注射器）you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make.
The wind-up radio
When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don’t have electricity and cannot afford batteries, to use it. The radio has a generator (發(fā)電機) which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design.
The Dyson cleaner
In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum (真空) cleaner which uses something called “cyclonic separation” to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds.
The Zapata fly-board
Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It’s possible to jump to incredible heights out of the water — over 30 feet. The basic fly-board model comes in at ￡4,200.
So keep dreaming and inventing. One day you might get it right.
【小題1】What can we learn about Adaptable glasses?
| A．They are very expensive. | B．The inventor is a student. |
| C．The glasses are fragile. | D．They don’t look very nice. |
| A．Adaptable glasses. | B．The wind-up radio. |
| C．The Dyson cleaner. | D．The Zapata fly-board. |
| A．helping people use cleaners more easily |
| B．making Dyson a rich businessman |
| C．keeping the house cleaner than before |
| D．taking the place of human cleaners |
