Sandstorms hit northwestern China's Gansu Province and North China's Inner Mongolia Autonomous Region on the first day this year. According to Sun Landong, a meteorologist with the Lanzhou Meteorology Observatory,visibility was less than 100 meters in Minqin, a Gansu county near Inner Mongolia, because of sand. When visibility drops to less than 1 kilometer,it is called a sandstorm. The sandstorm in Minqin blew up dust in neighboring towns, such as Baiyin, Wuwei, Jinchang and Lanzhou, the capital city of Gansu Province. Dust-laden winds also swept into Beijing. Brought by northwesterly blowing at more than 20 meters per second,dust first reached the capital's suburbs at 7 a. m,downtown areas at 9 a. m. The winds,which died down during the night,brought the temperature down to as low as 80C below zero and many flights put off their planned time from the city's airport.
It is quite rare for sandstorms,which are frequent between March and June,to happen in winter,when the earth is frozen. The sandstorms in Gansu and Inner Mongolia do not necessarily mean there will be more of them in the spring than last year,when they were serious,but Beijing is taking it very seriously. It is reported that Beijing will spend 6 billion yuan ( US 725 million) in preventing sandstorms in the capital and has already set up a spe­cial team to make sure what causes them.

hours later if it travels at a speed of 20 meters per second?
A.4. 2 B.1. 5 C.2. 0 D.2. 5
小題3:Why did sandstorms begin in the winter this year?
A.Because there was little snow this season.
B.Because a lot of trees have been cut down.
C.Because people took few measures to control them.
D.It is not mentioned in the passage.

Driving a Car is not just handing controls and judging speed and distance, it requires you to predict what other road users will do and get ready to react to something unexpected. When alcohol is consumed, it enters your bloodstream and acts as a depressant(抑制藥), damaging eyesight, judgment and co-ordination(協(xié)調(diào)),slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.
Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain. Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice. To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like a shower or having a cup of tea or coffee.
The present traffic ordinance states clearly that the limit of alcohol concentration is:
●50 milligrams of alcohol per l00ml of blood; or
●22 milligrams of alcohol per l00ml of breath; or
●67 milligrams of alcohol per l00ml of urine(尿液)
Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.
Any drive found drinking beyond the limit will be charged. The driver declared guilty may be fined a maximum of HK﹩25,000 and be sentenced to up to 3 years in prison and punished for 10 driving-offence points; or temporarily banned from driving.
The same punishment applies to failing to provide specimens (樣本) far breath, blood or urine tests without good excuse.
Drink driving is a criminal offence. Be a responsible, driver, think before you drink. For the safety of yourself and other road users, never drive after consuming alcohol.
小題1:The first paragraph is mainly about_____________.
A.the introductions of driving skillsB.the damage of drinking to your body
C.the effect of drinking on drivingD.the process of alcohol being absorbed
小題2:The underlined word ”it” in the second paragraph refers to “____”.
A.a(chǎn)lcoholB.a(chǎn)bsorptionC.bloodD.process
小題3: which of me following is TRUE according to the passage?
A.Drinking below the drink driving limit has no effect on driving.
B.Alcohol is taken in more quickly when drunk with fruit juice.
C.Having a cup of tea helps to get rid of alcohol from the body.
D.50milligrams of alcohol per l00ml of breath is below the drink driving limit.
小題4: A driver suspected of drink driving ____.
A.should provide specimens for testing
B.will be forbidden to drive for 3 years
C.will be punished for 10 driving-offence points
D.should pay a maximum fine of HK$25,000

Of the 7,000 languages spoken in the world today, linguists (語言學家) say, nearly half are likely to disappear this century. In fact, one falls out of use about every two weeks.
Some languages die out in an instant, at the death of the only surviving speaker. Others are lost gradually in bilingual (雙語的) cultures, as local tongues are edged out by the dominant (占主導地位的) language at school, in the marketplace and on television.
New research, supported by the National Geographic Society and the Living Tongues Institute for Endangered Languages, has found the five regions where languages are disappearing most rapidly. They are northern Australia, central South America, North America's upper Pacific coastal zone, eastern Siberia, and Oklahoma and the southwestern United States.
K. David Harrison, an associate professor of linguistics at Swarthmore College, US, said that more than half the languages had no written form and were vulnerable to loss and being forgotten." Their loss leaves no dictionary, no text, or no record of the accumulated knowledge and history of a disappeared culture.
Harrison and other researchers started their rescue project last year. They have been trying to identify and record endangered languages. They interviewed and made recordings of the few remaining speakers of a language and collected basic word lists. The individual projects, some lasting three to four years, involve hundreds of hours of recording speech, developing grammar and preparing children's readers in the obscure (逐漸沒落的) language. The research has concentrated on preserving entire language families.
"These are probably languages that cannot be brought back, but at least we made records of them," said Gregory Anderson, director of the Living Tongues Institute, in Oregon, US.
小題1:What does the passage mainly tell us?          
A.Many languages are quickly disappearing.
B.Some languages are disappearing because they are hard to remember.
C.Chinese is one of the languages that are disappearing.
D.Thanks to some researchers, many endangered languages have been rescued.
小題2:What does the word vulnerable in the fourth paragraph mean?  
A.easy to remember.B.easy to forget.
C.likely to be damaged.D.likely to be protected.
小題3:Which of the following is true according to the fifth paragraph?  
A.Harrison and other researchers are trying to find out why some languages died out.
B.Harrison and other researchers tried to start a rescue project.
C.Harrison and other researchers have concentrated on preserving all the languages.
D.Harrison and other researchers have done some rescue work on the obscure languages.
小題4:One of the things that Harrison and other researchers did was         .   
A.to have more people speak the disappearing language
B.to make records of the disappearing language
C.to limit dominant languages
D.to publish a dictionary of the disappearing language
小題5:What do you think is the suggested reason for some languages disappearing?     
A.Local tongues are gradually edged out by the dominant language at school, in the marketplace and on television.
B.The number of people who speak the languages are small.
C.There are no dictionaries for the languages.
D.No one make records of the languages, so they gradually disappear.

It was a village in India. The people were poor. However, they were not unhappy. After all, their forefathers had lived in the same way for centuries.
Then one day, some visitors from the city arrived. They told the villagers there were some people elsewhere who liked to eat frog’s legs. However, they did not have enough frogs of their own, and so they wanted to buy frogs from other places.
This seemed like money for nothing. There were millions of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached, and the children were sent into the fields to catch frogs. Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able to dream of a better future. But the dream didn’t last long.
The change was hardly noticed at first, but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often, and, there seemed to be more insects around lately.
The villagers decided that they couldn’t just wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (殺蟲劑)and medicines. Soon there was no money left.
Then the people realized what was happening. It was the frog. They hadn’t been useless. They had been doing an important job — eating insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.
Now, the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs. These sounds of the night now have a much deeper meaning.
小題1:.
. From Paragraph 1 we learn that the villagers      .
A.worked very hard for centuriesB.dreamed of having a better life

小題3:.
. What might be the cause of the children’s sickness?
A.The crops didn’t do well.B.There were too many insects.

Since the gene , called DAF-16 in worms, was found in many animals and in humans, the finding could open up new ways to affect aging ,immunity and resistance in humans the scientists said.
“We wanted to find out how normal aging is being governed by genes and what effect these genes have on other traits such as immunity,”said Robin May , who led the study.
Populations across the world are aging at a surprising pace , bring potentially big challenges for health and social care systems . A study by Danish scientists last year found that half of babies born in rich world today will live to celebrate their 100th birthday . Scientists are eager to find out how people age to try to develop drugs to help them stay healthier lives extend.
“What we have found is that things like resistance and aging tend go hand in hang “ May said in an interview
May’s team compared longevity ,stress resistance and immunity in four related species of worm. They also looked for differences in the activity of DAV-16 in each of the four species and found that they were all quite distinct.
May said DAF-16 was active in most cells in the body and was very similar to a group of human genes called FOXO genes , which scientists believe play a role in the aging process. “The fact that subtle differences in DAF-16 between species seem to have such an impact on aging and health is very interesting and many explain how differences in lifespan and related traits have arisen during evolution,”May said
小題1:In which section may the text appear in a newspaper?
A  Education   B  Science   C  Entertainment    D  Culture
小題2: According to May ,   
A resistance has a lot of to do with aging    B FOXO genes can be found in worms
C genes play the same role in difference species   D  new drugs will change the genes in older people
小題3:From the text we know that DAF-16   
A is a gene that is only found in worms     B can make people live longer
C has an effect on aging and immunity     D  has been quite familiar to scientists

Raymond Schneider politely elbowed his way through crowds of customers as he made for the candy bins at Dylan’s Candy Bar in Manhattan. Since he was laid off in December, Mr. Schneider, a 33-year-old designer, says he has become a “gummy junkie,” buying a lot of sweets every time he shops for groceries.
“Sugar is comforting,” he said. “There’s nothing more stressful than growing financial insecurity everywhere.”
The recession (經(jīng)濟衰退) seems to have a sweet tooth. As unemployment has risen, Americans, particularly adults, have been consuming growing amounts of candy, say candy makers, store owners and industry experts.
Theories vary on exactly why. For many, sugar lifts spirits dragged low by the economy. For others, candy also provides a reminder of better times. And not insignificantly, it is relatively cheap.
At Candyality, a store in the Lakeview neighborhood of Chicago, business has jumped by nearly 80 percent compared with this time last year, and the owner, Terese McDonald, said she was struggling to keep up with the demand for Bit-O-Honeys, Swedish Fish and Sour Balls.
“They put candy in their actual budget,” she said.
Many big candy makers are also reporting rising sales and surprising profits.
“Candy companies are relatively recession-proof,” said Peter Liebhold, chairman of the Smithsonian Institution’s work and industry division. “During the Great Depression, candy companies stayed in business.”
小題1:Raymond Schneider was set as an example to show ________.
A.many Americans were laid off in the recession
B.lots of Americans like candies
C.many Americans in the recession like sweets which are comforting
D.Americans are suffering much in the recession.
小題2: What does the underlined sentence “The recession seems to have a sweet tooth” mean?
A.Candy consuming rises while people are suffering bad effects of the recession.
B.The recession doesn’t have any bad effect on Americans.
C.Americans are optimistic even though they are out of employment.
D.Candy companies stayed in business during the Great Depression.
小題3:Which is NOT the reason why people in the recession like sugar?
A.It is relatively cheap.
B.It is comforting and can make a lot of profits.
C.It raises people’s spirits up.
D.It calls up people’s good memories.
小題4: The best title of the passage is ________.
A.Sugar Is Comforting
B.Candy Companies Stay In Business
C.Americans Have A Sweet Tooth

Tui Na and Your Emotional Health
In Traditional Chinese Medicine the body, mind and spirit cannot be divided and so the unique whole-body treatment in Tui Na can also be a use­ful treatment correcting any imbalances in the body's energy before symptoms and disease can de­velop. It also works to restore emotional harmony as well as physical health. This is why after a Tui Na treatment many people "feel good". Many peo­ple in China use Tui Na regularly to keep healthy and to deal with some specific illnesses.
Tui Na is performed on the clothed body and the patient is either lying on a couch or sitting on a chair. Therapists using a variety of strokes or movements will control the intensity and direction of pressure in an exact way. The unique rolling movement in Tui Na is one of the most difficult strokes to learn and students have to practice sometimes for many months on a rice bag before they are allowed to practice on the human body.
Stress
Tui Na is of course very useful for treating stress.
It distributes the energy around the whole body. It is be­lieved that Tui Na moves the strong energy in the tense muscles to the weaker areas, thus making a more balanced body. When your Qi (energy in the body) flow is balanced you feel relaxed and comfortable. Tui Na is especially useful for stiff shoulders and tense neck muscles.
Emotions
In Traditional Chinese Medicine each major organ is linked to an emotion. By balancing the energy in the organ, the relevant emotion will be calmed. When your emotions are out of control, you would usually turn to your doctor or perhaps a psychotherapist. But perhaps some people would not like to be seeing a psychotherapist or feel nervous about discussing their problems with others. With Tui Na one does not need to tell the therapist anything one does not want to. The treatment of Tui Na can deal with the problem itself — although if one does need to talk, then the safe space is there to do so. An active dialogue between the therapist and the patient will help to get a better effect.
How the major organs rule your emotions
Each major organ — the heart, the stomach, the spleen, the liver, the bladder, the kidneys, the lungs, etc. — is linked to a relevant emotion.
The heart is linked to joy, excitement and sadness. If the heart is out of balance, the patient may dream a lot at night and often forget something important in the day.
The stomach and spleen are connected with too much thinking or wor­rying — over anxiety. When the stomach is out of balance there is often a lack of energy. The patient often feels very tired and has no interest in do­ing anything at all.
The liver and gall bladder are linked to anger. In Chinese Medicine the eyes are connected with the liver, and many people who suffer from an­ger often suffer from eye problems. The gall bladder rules decision-making and too much energy here can lead to rashness, while if there is too little it can bring about indecision. Where there is a history of depression, the therapist would look to the liver.
The bladder and kidneys are linked to fear of all kinds, from simple anxieties and phobias to vague fears and worries.
The lungs are connected with feelings of grief and sadness. When there is a history of grief, the therapist would look to the lungs.
Tui Na is used in almost all the hospitals in China and very popular among Chinese people. It is a useful and valuable method of restoring Qi balance, when emotional and physical health is out of balance. Tui Na is one of the remaining secrets of Chinese Medicine.
小題1:According to the passage, which statement is TRUE about Tui Na?
A.Tui Na is a whole-body treatment and can't be divided into different parts.
B.Tui Na can be used to balance the diseases before they can develop in the body.
C.Tui Na can bring back not only physical health but also emotional health.
D.Tui Na only makes people "feel good" but do not actually cure disease.
小題2:How can the emotion be calmed?
A.By linking the organ to an emotion.
B.By telling the therapist anything one does not want to.
C.By discussing their problems with others.
D.By balancing the energy in the relevant organ.
小題3:When the stomach is out of balance,  .
A.the patient will have a stomachache
B.the patient will have a lot to worry about
C.the patient will have nothing to do
D.the patient will not feel like doing anything
