A gadget which makes water out of air could become the greatest househo1d invention since the microwave.
Using the same technology as a dehumidifier（除湿器），the Water Mill is able to create a ready supply of drinking water because it can always get it from an unlimited source—the air．
The company behind the machine says not only does it offer an alternative to bottled water in
developed countries, but it is a solution for the millions who face a daily water shortage．
The machine works by drawing in wet air through a filter（过滤器）and over a cooling instrument which changes it into water droplets．It can produce up to 1 2 liters a day．The Water Mill will also produce more water when storms pass over, as the amount of water which is contained in the air increases.

In keeping with its eco-development, the machine uses the same amount of electricity as three lights.
Inventor Jonathan Ritchey said: “The demand for water is off the chart. So people are looking for freedom from water distribution systems that are shaky and unreliable.”
The machine, which is about 3 feet wide, is likely to cost ￡800 when it goes on sale here in the spring. Its make

r, Canadian Firm Element Four, roughly calculates that a litre of water cost around 20p to produce.
Environmentalists state that half the world’s population will face water shortage because of climate change by 2080. One in five is said to lack access to safe drinking.
The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent, but in Britain that won’t be much of a problem.
63．What does the underlined word “it” refer do?
A．Drinking water.       B．Invention. C．Microwave.      D．Water Mill.
64．What do we learn about the machine?
A．It works in the same way as microwaves.
B．It is very expensive for families to afford.
C．It absorbs steam and turns it into water.
D．It helps to make the water clean to drink.
65．What does the passage lead us to believe?
A．The cost of water will go up. B．Bottled water will disappear sooner.
C．The machine is energy saving. D．The machine will be popular worldwide.
66．What’s the best title for the passage?
A．A New Way to Solve Water Problem.    B．A Machine to Make Water out of Air.
C．A Dehumidifier to Produce Water.     D．An Absolutely New Invention

Keeping a Diary in English
Our teacher asks us to keep a diary in English. I   36   doing so because I think keeping a diary in English is one of the effective ways to   37   our English writing ability.
Compared with   38   forms of writing, it is shorter and   39   less time. It can help us to   40   the habit of thinking in English. 41   we persist in(坚持) this practice, gradually we’ll learn how to express ourselves in English. In keeping a diary in English,   42   can use the important phrases and sentences we’ve   43   in or out of English classes to describe our   44 , and this way we can master and use freely   45   we’ve learned, which will do good 46 us in English learning. But   47   we certainly run up against many difficulties. In the first place, it often happens that we have   48   finding proper words and phrases to give expression to our mind. Secondly, there   49   many idiomatic (惯用的) ways of saying things in Chinese. And it is extremely hard   50   us to put them into English properly.
As far as I am concerned, my suggestion is that we   51   always have a notebook and a Chinese-English dictionary within easy reach. Whenever   52   beats(难倒) us, we can first put it down in our notebook and then look it up in our dictionary. We can also turn to our English teacher for   53 , if necessary.
In short, I believe that it is of   54   use to keep a diary in English for the development of our   55   skills.

Let’s do some sleep math．You lost two hours of sleep every night last week because of a big project due on Friday．On Saturday and Sunday，you slept in，getting four extra hours．On Monday morning，you were feeling so bright—eyed that you only had one cup of coffee，instead of your usual two．But don’t be cheated by your energy．You’re still carrying around a heavy load of sleepiness，or what experts call “sleep debt”一in this case something like six hours，almost a full night’s sleep．
Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get．It’s a shortage that grows every time we skim some extra minutes off our nightly sleep．“People get more sleep debt gradually without being noticed，”says William C．Dement，founder of the Stanford University Sleep Clinic．Studies show that such short term sleep lack leads to a foggy brain，worsened vision，and trouble remembering．Long-term effects include obesity(肥胖)，insulin(胰岛素)resistance，and heart disease．A survey by the National Sleep Foundation reports that we’re losing one hour of sleep each night——more than two full weeks of sleep every year．
The good news is that，like all debt，with some work，sleep debt can be repaid．Adding all extra hour or two of sleep a night is the way to catch up．For the long-term lack of sleep， take it easy for a few months to get back into a natural sleep pattern．
Go to bed when you are tired，and allow your body to wake you in the morning(no alarm clock allowed)．You may find yourself catatonic(有紧张症的)in the beginning of the recovery cycle：expect to have ten hours shut—eye per night；As the days pass，however，the amount of sleeping time will gradually decrease．
So earn back that lost sleep and follow the rules of your innate(固有的)sleep needs. You’ll feel better．“When you put away sleep debt,you become a superman,”says Stanford"s Dement，talking about the improved mental and physical capabilities that come with being well rested．
53．If you have short-term sleep lack，you may___________．
A．put on weight    B．get heart disease  C．hate eating food   D．have a poor sight
54．The example of sleep math is used to show______．
A．in what case you build up a sleep debt
B．in what way you can make up for lack of sleep
C．why you are energetic even without enough sleep
D．why you need six hours’sleep every night
55．By saying the underlined sentence，Dement means that______．
A．you need a lot of sleep to be a superman
B．you will be in a good state with enough sleep
C．you need to be a superman to repay sleep debt
D．you will become a superman with more sleep debt
56．What might be the most suitable title for the passage?
A．How can you keep energetic?    B．What is sleep debt?
C．Can you catch up on lost sleep? D．Can coffee refresh you?

How often do you change your hairstyle or ask for new dresses? You may be   31 to follow trends（潮流）in Western countries, but young people in the United States don’t care as much about
32 as you do.
A recent survey(调查) among high school   33 in China, Japan, South Korea and the US found that   34   teenagers care more about their appearance than young people in the US.
This survey was held in 156 high schools in the four countries. More than 7,000 teenagers were
35 about their views on life and the world. South Koreans, at 83 per cent, cared most about their looks. They were   36   by the Chinese and Japanese, while US students showed the least interest in fashion at only 33 per cent.

What is it that makes people happy? Youth, health, a good job, good looks, a flash car? None of these things, Spanish experts say.
The concept（概念） of happiness is thought to be determined by genetics, while the rest depends on childhood environment and the process（过程） of growing up. Perhaps the most surprising thing about happiness is coming under increasingly close examination in Spain.
As the nation rises to the club of the world"s wealthiest countries, people are discovering that material（物质的） things do not bring happiness.
"Most people use money as a measure of human value," says Jesus Ynfante, author of a book on Spain"s 300 biggest fortunes. "Expensive products are regarded as the best. The rich are admired simply for being rich," Ynfante said.
Yet psychologists（心理学家） warn that happiness as a moment of ecstatic pleasure(狂喜)--something that, by definition（定义） ,cannot last--while others speak of it as peace and acceptance of oneself. Polls(问卷调查) in different countries indicate that between 65 and 85 percent of the world"s population regard themselves as reasonably happy.
Around 40 percent of a person"s happiness is that it has little to do with age, health, wealth, or other values thought to be important in Western society. For most Spaniards, happiness is linked with feeling close to other people. Happy people accept their limitations and set themselves reachable goals, experts say.
There are life-style choices that favour happiness, such as exercise, eating carbohydrates and exposing oneself to sunlight. But the main secret of happiness is to take pleasure in small things.
“If you are given a choice between eternal（永久的)happiness and a cheese sandwich, take the sandwich,” advises musician Julian Hernandez.
58. Spain, as this passage tells us, __________.
A. has built more clubs than the other countries
B. has owned the largest group of experts
C. has become one of the richest countries in the world
D. has produced the most wealth in the world
59. It can be concluded that Jesus Ynfante is__________.
A. a famous expert           B. a famous psychologist
C. one of the richest Spaniards   D. familiar with the richest Spaniards
60.As psychologists warn in this passage, people can"t feel happy even if they_________.
A. have too much money      B. only care about themselves
C. don"t do any homework     D. have a few relations
61 Happy people, as we can find in this passage, __________.
A. are always full of feelings                  B. are always born in rich families
C. always enjoy every achievement they get       D. always look down upon themselves

D
Jupiter is the largest planet in our solar system. It is also one of the most interesting. It was named after Jupiter, the most important of the Roman gods, and nicknamed the “King of Planets.” It is the fifth planet from the sun and the fourth brightest object in the sky. Before the invention of the telescope, Jupiter was thought to be a bright star.
In 1610, the famous astronomer Galileo realised that Jupiter was actually a planet. He also noticed that it had four large moons. These are known as the Galilean moons. The biggest is Ganymede, and it is larger than the planets Pluto and Mercury. Next in size is Callisto, which is the farthest away from Jupiter. It is the closest to the planet, and has a lot of active volcanoes. The smallest of the Galilean moons is Europa. Europa is covered in ice, and scientists believe there may be an ocean underneath.
Galileo"s discovery that Jupiter was not a star but a planet was very important. Before this time, people believed the Earth to be the centre of the universe. They thought that the sun, stars, and other planets all revolved around the Earth. However, Galileo proved that the sun was at the centre of the universe!
(A) Jupiter is farther out in the solar system than Earth, so it takes longer to revolve around the sun. (B) However, a day on Jupiter is much shorter, only 9.8 Earth hours. (C) This is because it spins(旋转) a lot faster than the Earth does. (D)
Another of Jupiter"s interesting features（特性） is its “Great Red Spot.” On the surface of the planet is a large red spot. The spot is actually a huge storm like a hurricane, but bigger. It covers an area twice as big as the Earth and has been going on for at least 400 years!
62. What is the passage mainly about?
A. Features of the planet Jupiter.
B. Differences between Jupiter and other planets.
C. Galileo"s accomplishments in astronomy（天文）.
D. How Jupiter moves in the solar system.
63. According to Paragraph 3, why is Galileo"s discovery important?
A. Because Jupiter was thought to be smaller than Earth.
B. Because people knew that Earth is not the only planet.
C. Because it meant that the planet goes around the Earth.
D. Because it proved that Earth is not the centre of the universe.
64. The underlined word “revolved” in the third paragraph is closest in meaning to           .
A. approached        B. stopped            C. sped up            D. circled
65. Where would the following sentence best fit into Paragraph 4, (A), (B), (C) or (D)?
This means that one year on Jupiter is as long as 11.6 Earth years.
