These days we hear a lot about how air pollution is changing temperatures on the earth. New evidence from a mountaintop in China now suggests that pollution can also change the amount of rain and snow that falls in some places.
Usually, more rain falls in mountainous places than in flat areas upwind from the mountains. That’s because air can hold a lot of water. When wind blows wet air up a mountainside, the air gets colder. This temperature change often forces water to fall as rain or snow.
In recent years, however, many mountainous areas in the western United States have been getting less rain than normal. Mountains that are downwind from cities have experienced the biggest drops.
Some scientists have theorized(推理)that pollution drifts (趋势)from the cities into the mountains, affecting rainfall, but proving this link has been difficult.
Searching for answers, a team led by a scientist from the Hebrew University went to s mountain in China called Mount Hua, which is 2,060 meters tall and lies about 120 kilometers east of the Chinese city Xi’an. Since 1954, scientists have been collecting details about rainfall, humidity(湿度), and visibility(能见度)in the area.
Using this data, the scientists compared rainfall on Mount Hua to rainfall in the nearest city, Huayin, on days with different levels of visibility. When the air was clear and people could see as far as 20 km, the scientists found that 65% more rain fell on the mountain than in the city.
But when the air was smoggy, allowing only 8 km of visibility through the mist, the mountain received just 20% more rain than the city. The new data supports the theory that pollution affects rainfall.
Some scientists believe that there are other explanations for the numbers. It’s possible, for example, that natural particles(微粒)in the air, rather than particles produced by pollution, are affecting visibility.

Over three years ago, the French director Jean—Pierre Jeunet and actress Audery Tautou won people's hearts with their popular comedy "Amelie". The fairytale-like film tells the story of a single waitress who helps lonely people find love.
Now,
the pair
are back with another film. "A Very Long Engagement" is a film about World War I. It received 12 nominations(提名)from France's Cesar Awards last week, including best film, best director and best actress.
Mathilde (Audrey Tautou) is a young woman who becomes disabled after suffering from a disease as a chilD.She lives on a farm with her aunt Benedicte (Chantal Neuwith) and uncle Sylvain (Dominique Pinon). She receives a regular income from the wealth left to her by parents. She has a fierce and loyal love for Manech (Gaspard Ulliel), her childhood boyfriend and fiance‘(未婚夫). He is the son of a lighthouse keeper. When he goes off to the battle fields of World War I, she is lonely, but confident he will return. Early on in the film, five French soldiers are sentenced to death because of intentionally hurting themselves to escape duty. They are pushed into the German's line of fire. They are made to protect themselves without guns. One of them is Manech. Mathilde firmly believes that Manech is alive. She is determined to find him. She hires a private detective to find out what really happened to those French soldiers. Through letters, photographs, interviews with people who remain alive after the war, and wartime papers, Mathilde discovers how cruel the war is. She also sees the heroism of ordinary men, trying to stay alive on the battle field.
It's funny, sweet and sometimes sad to watch. Jeunet gives a realistic portrait of warfare. Tautou remains the emotional center of the film. She shines as Mathilde, a woman who suffers one failure after another, but refuses to give up her seek for her lover. It's a film for all romantic people who are in search of true love.

Researchers at the University of Bedforshire have developed a new technique for powering electronic device(装置). The system, developed by Professor Ben Allen at the Centre for Wireless Research, uses radio(无线电) waves as power.
Believed to be a world first, the team claims it could eventually eliminate (or get rid of )the need for conventional batteries. The university has now filed a patent application to secure the only rights to the technique.
Professor Allen and his team have created a system to use medium wave frequencies to replace batteries in small everyday devices like clocks and remote controls.
The new technique uses the “waste” energy of radio waves and has been developed as part of the university’s research into “power harvesting”. Professor Allen said that as radio waves have energy―like light waves, sound waves or wind waves―then, in theory, these waves could be used to create power.
“The emerging(新兴的)area of power harvesting technology promises to reduce our reliance on conventional batteries,” he said. “It’s really exciting way of taking power from sources other than what we would normally think of.”
The team is now waiting for the results of the patent application to secure recognition of the technique. Professor Allen said that the team’s achievements had all been done in their “spare time”. “Our next stage is to try and raise some real funds so that we can take this work forward and make a working prototype(模型)and maybe partner up with the right people and take this to a full product in due course,” he said.
“Power harvesting has a really important part in our future, because, just in this country, we dispose of somewhere between 20,000 and 30,000 tonnes of batteries in landfill(垃圾填理)sites every single year-that is toxic chemicals going into the ground.”
He added that development of the product could also be “commercially beneficial”. “The market for this is several billion pounds. We’ve seen market predictions for 2020 which have these kinds of figures, so there’s a lot of commercial potential in this area,” he said.
Pro-Vice Chancellor at the University of Bedfordshire, Professor Carsten Maple, said, “This type of work is a reflection of the university’s growing reputation and experience in conducting innovative(创新的)research.”

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body.
Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs.
Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we’ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body’s cells. The body’s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity.
The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common.
To stop this vicious(恶性的) circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It’s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach.

foods with natural enzymes help people keep fit

Afraid that her son would be too tired, Ms. Wendy would sometimes tell the boy to skip school, but each time, Fabian would insist on going to school.
“I don’t like
it
because when I return to school, I don’t know what’s going on,” the 12-year-old boy explained. He suffers for SMA-a neuromuscular(神经肌肉的)disease that leads to weakness in muscles-and gets around in a wheelchair.
Fabian’s determination to excel in his studies was evident when he was disappointed that he got a total score of 236 yesterday in his Primary School Leaving Examination. He was hoping for a score of at least 240, but his mother was full of pride. “I am happy with his results. He’s very motivated,” said Ms. Wendy.
When Fabian was two months old, he was diagnosed with SMA. Ms. Wendy, who used to go to other homes to teach piano lessons, started teaching lessons at home so she could take care of her son. Fabian proved to be a fighter. Ms. Wendy said, “ He would study every day on his own even though he was weak and his spine(脊柱)was already starting to curve quite badly.”
Fabian is also active in the Singapore Disability Sports Council, where he plays boccia(滚球), a ball sport for those who require a wheelchair due to physical disability.
At just 133cm tall and weighing 14kg, he knows that he will have to rely on others all his life. “I’m afraid that when my parents grow older, they will not be able to carry me and that there will be nobody to carry me,” said Fabian. “But for now, I feel lucky that I get to go out and do a lot of things that I thought I couldn’t.”
His dreams aren’t lofty(崇高的)either-all he want to be able to do is work and provide for his parents. “I just want to study hard so that I can be a businessman, like my dad.” He is planning to apply to study at Victoria School.

Remembering names is an important social skill. Here are some ways to master it.
●Recite and repeat in conversation.
When you hear a person’s name, repeat it. Immediately say it to yourself several times without moving your lips. You could also repeat the name in a way that does not sound forced or artificial.
●Ask the other person to recite and repeat.
You can let other people help you remember their names. After you’ve been introduced to someone, ask that person to spell the name and pronounce it correctly for you. Most people will be pleased by the effort you’re making to learn their names.
●Admit you don’t know.
Admitting that you can’t remember someone’s name can actually make people relaxed. Most of them will feel sympathy if you say. “I’m working to remember names better. Yours is right on the tip of my tongue. What is it again?”
●Use associations.
Link each person you meet with one thing you find interesting or unusual. For example, you could make a mental note: “Vicki Cheng-tall, black hair.” To
reinforce
your associations, write them on a small card as soon as possible.
●Limit the number of new names you learn at one time.
When meeting a group of people, concentrate on remembering just two or three names. Free yourself from remembering every one. Few of the people in mass introductions expect you to remember their names. Another way is to limit yourself to learning first names. Last names can come later.
●Go early.
Consider going early to conferences, parties and classes. Sometime just a few people show up on time. There’re fewer names for you to remember. And as more people arrive, you can hear them being introduced to other an automatic review for you.

COOL INVENTIONS
CHARGE ON THE GO
From school to band practice, the Venturi Eclectic is an Earth-friendly way to get where you want to go. This battery-powered, zero-emission(meaning it doesn’t pollute the air) vehicle runs mainly on renewable energy. Solar panels on the Eclectic’s roof absorb sun rays when you’re driving. On windy days, you can connect a machine to the car’s roof collects energy from the wind while you’re parked. The Eclectic’s top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged. Zipping (迅速行进)round the neighborhood has never been better.
WATER CLOCK
Here’s an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock’s tank(箱)with water, add some lemon juice, and the clock will display the time without the need for environmentally harmful batteries. There are two sets of metal electrodes(电极)inside the water tank. Water contains ions(离子)that carry negative and positive charges. These ions complete a charge between the electrodes creating enough energy to power the clock. Just refill the tank every few weeks, and this clock will keep on ticking.
LAND ROCKET
Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the 1,000-mile-an-hour barrier. (The current record is 763 miles an hour.) a concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine. Then a rocket fires up, pushing the SSC past 1,000 miles an hour. In order to keep the car streamlined(流线型的)the driver lies back at a 45-degree angle.
COOL CAMERA
You’re having a blast at your friend’s birthday party. But when it’s time to bring out the cake, everyone crowds around, blocking your view. No worries. Throw the Triops into the air, and this clever camera captures the view from above. The Triops can take three pictures at once, each from different angles. You can also record sounds and command the Triops to start shooting whenever it hears that noise. That’s one smart camera.

I didn’t realize how short I was until I started school. There, a few kids picked on(欺负)me, calling me names. Then I knew. After that, I began to hate the first day of school each year. I didn’t know who was new and would stare at me as I struggled to climb the school bus stairs. Some of the kids would point and say, “Look at that kid. Look at her.”
As time went on, I just tried to smile and accept the fact that I was going to be noticed my whole life. I was determined to make my uniqueness an advantage rather than a disadvantage. My friends became increasingly protective. They’d help me up the bus steps. If people were cruel, they would take them aside and correct them.
What I lacked in height, I made up for in personality----my ability to laugh, even at myself. For example, one time I was reaching into the washing machine at my parents’ house to grab the wet clothes. I fell all the way in and yell for Mother, who was sitting nearby reading the paper. Watching feet flying everywhere, she laughed quietly and said, “I should leave you in there.” I laughed with her.
I’m 47 now, and
the stares have not decreased
as I’ve grown older. People ask my friends if I live in a dollhouse. They look in disbelief when they see me get out of my car on the driver’s side. During those times, I try to keep a good attitude. When people are rude, I remind myself, “Look what else I have----a great family, nice friends…”

The Internationa1 Space Station allows astronauts to live in space for extended amounts of time, enabling them to explore the outside universe and conduct many experiments. However, nothing like that exists for our oceans, and thanks to the high water pressure, ocean researchers are able to explore what lies undersea for very short periods of time.
They are therefore never able to fully explore the deep inside areas of our oceans. However, if French architect Jacques Rougerie has his way, that will change soon.
Jacques has designed a ship that will allow researchers to spend a long period of time observing the sea life and conducting experiments. The huge l67ft. ship, named ‘Sea Orbiter’, consists of two areas—one above the water where the scientists and crew will live, and a lower pressurized deck (甲板), where scientists will be able to spend as much time as they wish. Since it is powered by sea currents and wind, he expects it to drift (漂流) along the oceans slowly, taking about two years to
circumven
t
the globe.
Jacques will make their life as comfortable as possible in the ship. Besides being equipped with the latest sailing tools and communication equipment, the ship will also have a gym, a television and a DVD player! And these guys will not be eating freeze-dried food like astronauts. Instead, Jacques, an accomplished chef, plans on cooking them delicious meals every day.
The biggest problem to this giant ship is the cost, which is expected to be over $500 million—per ship! However, Jacques, who strongly believes that the secrets of our oceans may be the key to solving global warming and a vital supply for food and medicine in the future, is confident he will be able to convince governments all over the world to help out, and expects to start construction on not one, but four or five of these amazing ships soon!
1.
Why can’t ocean researchers explore the deep oceans for a long time?
A.
Because they can’t stand the high water pressure.
B.
Because it’s too cold in deep ocean.
C.
Because time for experiments is too limited.
D.
Because it’s dangerous to observe the sea life.
2.
The underlined word “circumvent ” probably means
.
A.
fly away
B.
go around
C.
travel through
D.
move into
3.
From the fourth paragraph we can learn that
.
A.
Jacques intends to design the ship mainly for sightseeing and traveling
B.
living a comfortable life helps to do the ocean research quickly
C.
it’s much more expensive to eat freeze-dried food
D.
researchers on Jacques ’ ship will live more comfortably than astronauts
4.
In Jacques’ opinion, which of the following is not the purpose of the undersea research?
A.
To find supply for food in the future.
B.
To find supply for medicine in the future.
C.
To draw governments’ attention to the construction of the ship.
D.
To solve the global warming.

There are two basic ways to see growth: one as a product, the other as a process. People have generally viewed personal growth as a result or product that can easily be identified (识别) and measured. The worker who gets a rise, the student whose grades improve, the foreigner who learns a new language—all these are examples of people who have measurable results to show for their efforts.
By contrast, the process of personal growth is much more difficult to determine, since it is a journey and not the specific signposts or landmarks along the way. The process is not the road itself, but rather the attitudes and feelings people have, their caution or courage, as they meet with new experiences and unexpected obstacles (障碍). In this process, the journey never really ends; there are always new ways to experience the world, new ideas to try, new challenges to accept.
In order to grow, to travel new roads, people need to have a willingness to take risks, to face the unknown, and to accept the possibility that they may “fail” at first. How we see ourselves as we try a new way of being is extremely important to our ability to grow. Do we notice ourselves as quick and curious? If so, then we tend to take more chances and to be more open to unfamiliar experiences. Do we think we’re shy and indecisive? Then our sense of fear can cause us to hesitate, to move slowly, and we think we’re slow to adapt to change or that we’re not smart enough to deal with a new challenge. Then we are likely to take a more passive role or not try at all.
These feelings of insecurity (无把握) and self-doubt are both unavoidable and necessary if we are to change and grow. If we protect ourselves too much, then we stop growing. We become trapped inside a shell of our own making.
1.
Which of the following can be viewed as the process of personal growing?
A.
Helen was always willing to accept challenges.
B.
Jane won the first prize in the speech competition.
C.
Jerry picked up French during his stay in Paris.
D.
Father’s salary rose from 5,000 to 7,000.
2.
For personal growth, the writer is in favor of ________.
A.
being cautious(谨慎的) with changes
B.
having little interest in new things
C.
staying away from failures and challenges
D.
having an open mind to new experiences
3.
How do you understand the last sentence of this passage?
A.
We are trapped and injured.
B.
Our body is trapped and stops growing.
C.
We get stuck in what we are doing and can not achieve real growth.
D.
We can’t protect ourselves and are trapped by others.
