There are many wetlands(湿地) in China and some of them have become the world’s important wetlands. The Chinese Yellow Sea Wetlands are among them. They are in Yancheng，Jiangsu Province. They are home of many different kinds of birds and animals. The world’s largest Milu Deer Nature Reserve(自然保护区) is in them. More than 700 milu deer live freely there.
The temperature in the wetlands is usually neither too high nor too low. There is a lot of rain and sunshine，too. They are really good places for wildlife. Offering food and home for some special kinds of animals and birds is not the only reason why we need to protect wetlands.
Wetlands are important because they also prevent flood. But some people want to change the wetlands to make more space for farms and buildings. This means there will be less and less space for wildlife.
Luckily, more and more people are beginning to realize the important of wetlands and wildlife. Every year, on February 2nd many activities are held to tell people more about wetlands around the world.
小题1: Which animal is mentioned in the passage?

A B C D
小题2:Usually the weather in the wetlands is ____.

A．hot

B．mild

C．cold

D．dry

小题3:The reasons for protecting wetlands are the following except that ______

Alan Izhar-Bodner, an Israeli inventor, has developed a swimming suit for divers to breathe underwater without carrying heavy oxygen tanks. His suit makes use of the air that is dissolved（溶解）in water, just like fish do.
The system uses the Henry Law which states that the amount of gas that can be dissolved in a liquid is proportional (成比例的)to the pressure on the liquid. Raise the pressure ---more gas can be dissolved in the liquid. Decrease the pressure --- less gas dissolved in the liquid releases the gas. This is exactly what happens when you open a can of soda; carbon dioxide gas is dissolved in the liquid and is under pressure in the can. Open the can, releasing the pressure, and the gas fizzes(嘶撕作响)out.
Bodner's System obviously uses a special machine to lower pressure in part of a small amount of seawater taken into the system; dissolved gas is taken out. The patent（专利）reads: A self-contained open-circuit（循环）breathing instrument for use within a body of water naturally containing dissolved air. The instrument is adapted to provide breathable(可吸入的)air. The instrument contains an inlet for taking out a quantity of water from the body of water. It further contains a separator for separating the dissolved air from the quantity of water, thus gaining the breathable air. The instrument further contains an outlet for expelling (驱逐)the separated water back into the body of water, and another outlet for removing the breathable air and supplying it for breathing. The air is supplied so as to enable it to be expelled back into the body of water after it has been breathed .
Human beings have been thinking about how to breathe underwater since they started swimming. This long-held desire plays an important part in one of the first great science fiction novels, Jules Verne's 20,000 Leagues Under the Sea.
小题1:It can be inferred from the passage that____________ .

A．the less pressure it is, the less carbon dioxide gas is dissolved in the liquid

B．the deeper one dives into the ocean, the less gas is dissolved in the water

C．the greater pressure it is, the more carbon dioxide gas is dissolved in the liquid

D．the deeper one dives into the ocean, the more gas is dissolved in the water

小题2:This passage is mainly about __________.

A．how Bodner invented the instrument for breathing underwater

B．why Bodner invented the instrument for breathing underwater

C．how Bodner's instrument for breathing underwater works

D．how Bodner's instrument is used by divers for breathing underwater

小题3:From the passage we learn that __________.

A．a separator is used to expel breathable air back into the body of water

B．a separator is used to separate the air from the water so as to make use of the water

C．The breathable air removed from an outlet will eventually go back to the body of water.

D．The breathable air removed from an outlet will immediately go back to the body of water.

London—coffee protects mice from radiation and could get the same way in humans, according to Indian scientists.
Scientist at India’s Bhabha Atomic Research Center discovered that mice injected with caffeine (咖啡因)remained alive after high doses(剂量)of normally lethal radiation.
Although the study was limited to animals, Kachadillilli George, head of the research team, believes the findings could have implications (something suggested ) for humans .
“It does suggest that coffee might have some beneficial effects in protecting against radiation,” he told New Scientist magazine late last month.
George and his team injected 471 mice with caffeine and left them uncovered to 7.5 grays of gamma radiation(伽玛射线),enough to kill most mice. But 25 days later 70 percent of the mice that had received 80 milligrams(毫克)of caffeine per kilogram of body weight were still alive.
On the contrary all 196 mice that had been left uncovered to the same radiation but had not been given any caffeine died.
小题1:George and his team drew the conclusion from .

A．the magazine

B．their invention

C．the experiment

D．their experience

小题2:From the news, we know can be protected from radiation.

D．these mice hadn’t been given enough caffeine

小题4:Which is the best title of the article?

A．Human and Mice	B．New Radiation Defense—Coffee
C．Deadly Radiation—Gamma Radiation	D．Mice Died of Caffeine

小题5:In paragraph 2,the underlined word “ lethal ”means .

“If you want to see a thing well, reach out and touch it!”
That may seem a strange thing to say. But touching things can help you to see them better.
Your eyes can tell you that glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is.
When you feel all these about the ball, you really see it.
With your skin, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too.

Pigs are always considered dirty animals because they roll in mud．But in fact they prefer being quite clean．They cover themselves with mud to help stay cool．During cooler weather, they prefer to stay clean．So do elephants,who also cover themselves in dust or mud to keep cool． When they find a place with clean water they will take a bath，using their long noses to give themselves—or each other—a nice shower
Some animals use dust to get clean．Chinchillas (南美洲栗鼠) have very fine fur． They don`t like to take water baths because water is not warm enough for them．So, instead, they roll around in fine dust．The dust helps to keep their fur and skin dry．This protects them from disease
Usually, a small bird is a light meal for a crocodile．But when a crocodile wants its teeth cleaned．it lies on the ground with its mouth open．The crocodile bird goes in and picks out any parasites(寄生虫)between the crocodile`s teeth or under its tongue．The crocodile gets its mouth cleaned，and the crocodile bird gets dinner．
You wouldn`t think fish would need baths．But some undersea parasites live under the fish`s skin．“Cleaner”fish，like the wrasse(隆头鱼)，help take them away．The wrasse stands on its head and dances to signal a big fish that it is ready to go into the cleaning business．The big fish will stop moving and open its mouth wide so the wrasse can swim inside and pick out parasites and bits of food．

Parents who feel disappointed at their teenagers’ failure to pay attention in class, and inability to sit quietly long enough to finish homework or plan ahead, should take solace. Their children are not being lazy or careless, according to new research.
The research has found that teenagers’ brains continue developing far longer into adulthood than we used to think. Teens may look like young adults but their brain structure is similar to that of much younger children.
“It is not always easy for teens to pay attention in class without letting their minds wander, or to ignore distractions from their younger brothers or sisters when trying to solve a maths problem,” said Dr Iroise Dumon-theil. “But it’s not the fault of teenagers that they can’t pay attention and are easily distracted. It’s to do with the structure of their brains. Teens simply can’t think as well as an adult.”
The research showed that the brain of a teenager works less effectively than that of an adult. “We knew that the front of the brain of teens functioned in a chaotic (混乱的) way but we didn’ t realize it continued until the late 20s or early 30s,” said Dr Sarah-Jayne Blakemore, who led the research.
Chaotic thought patterns are a result of teenagers’ brains containing too much grey matter — the cell bodies and connections which carry messages within the brain. As we age, the amount of grey matter in our brain reduces.
“What our research has shown is that there is simply too much going on in the brains of teens,” said Blakemore. “The result is that their brain energy and resources are wasted and their decision-making process is badly influenced. Adults, on the other hand, have less grey matter. This means that the brain works far more effectively.”
小题1:The underlined word “solace” in Paragraph 1 may mean _____.

A． notice

B．medicine

C．comfort

D．action

小题2:When making decisions, _____.

A．teens’ brains continue to do much needless work

B．the grey matter in young children’s front brain becomes active

C．people are not likely to be distracted until their late 30s

D．adults are more independent than teens

小题3:What is the effect of having too much grey matter?

A．It makes us always feel disappointed.

B．It makes us more intelligent.

C．It had a bad effect on the growth of teens.

D．It had a bad effect on decision-making.

小题4:What’s the text mainly about?

A．Teens have different brains from those of children.

B．Adults work more effectively than teens.

C．Grey matter makes teens unable to pay attention.

D．Brain energy is wasted in the brain’s activity.

Ammie Reddick from East Kilbride, Lanarkshire, was only 18 months old when she had the accident that had scarred（留下创伤） her for life. The curious child reached up to grab the wire of a hot kettle in the family kitchen and poured boiling water over her tiny infant frame.
Her mother Ruby turned round and, seeing Ammie horribly burnt, called an ambulance which rushed her daughter to a nearby hospital. Twenty percent of Ammie’s body had been burned and all of her burns were third-degree. There, using tissue taken from unburned areas of Ammie’s body, doctors performed complex skin transplants to close her wounds and control her injuries, an operation that took about six hours. Over the next 16 years, Ammie underwent 12 more operations to repair her body.
When she started school at Maxwelton Primary at age 4, other pupils made cruel comments or simply wouldn’t play with her. “I was the only burned child in the street, the class and the school,” she recalled, “some children refused to become friends because of that.”
Today, aged 17, Ammie can only ever remember being a burned person with scars; pain is a permanent part of her body. She still has to have two further skin transplants. Yet she is a confident, outgoing teenager who offers inspiration and hope to other young burns victims.
She is a member of the Scottish Burned Children’s Club, a charity set up last year. This month, Ammie will be joining the younger children at the Graffham Water Center in Cambridgeshire for the charity’s first summer camp. “I’ll show them how to get rid of unkind stares from others,” she says. Ammie loves wearing fashionable sleeveless tops, and she plans to show the youngsters at the summer camp that they can too. “I do not go to great lengths to hide my burns scars,” she says, “I gave up wondering how other people would react years ago.”
小题1:How many operations has Ammie already had?

A．Twelve

B．Thirteen

C．fourteen

D．Fifteen

小题2:What did other children do when Ammie first went to school?

A．They were friendly to her.	B．They showed sympathy to her.
C．They were afraid of her.	D．They looked down upon her.

小题3:Ammie will teach the younger children at the Graffham Water Center to___________.

A．face others’ unkindness bravely	B．hide their scars by proper dressing

小题4:Which of the following words can’t properly describe Ammie?

A．Courageous

B．Confident

C．sensitive

D．Outgoing

Most earthquakes occur within the upper 15 miles of the earth’s surface, but earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much.
The extent of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set (坚立架), it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir was not strong, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building sites. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result.
There is one type of earthquake disaster that little can be done about. This is the disaster caused by seismic (地震的) sea waves, or tsunamis (海啸). These are often called tidal waves, but the name is incorrect. They had nothing to do with tides. In certain areas, earthquakes take place beneath the sea. These submarine earthquakes sometimes give rise to seismic sea waves. The waves are not noticeable out at sea because of their long wave length. But when they roll into harbors, they pile up into walls of water 6 to 60 feet high. The Japanese call them “tsunamis” meaning “harbor waves”, because they reach a sizable (相当大的) height only in harbors.
Tsunamis travel fairly slowly, at speeds up to 500 miles an hour. An earthquake warning system is in use to warn all shores likely to be reached by the waves. But this only enables people to leave the threatened shores for higher ground: There is no way to stop the oncoming wave.
小题1:Which of the following can NOT be concluded from the passage?

A．The number of earthquakes is closely related to the depth.

B．Roughly the same number of earthquakes occur each year.

C．Earthquakes are impossible at depths over 460 miles.

D．Earthquakes are most likely to occur near the surface.

小题2:The destruction of Agadir is an example of .

A．faulty building construction

B．an earthquake’s strength

C．widespread panic in earthquakes

D．ineffective instruments

小题3:According to the passage, the waves caused by submarine earthquakes are not noticeable out at sea because of .

A．their high speed

B．the wide shores

C．their silent movements

D．their long wave length

小题4:The significance of the slow speed of tsunamis is that people may .

A．help reduce fear

B．find ways to stop them

C．be warned early enough

D．develop warning systems

小题5:According to the passage, the number of factors that may determine the extent of the disaster in an earthquake is .

A．two

B．five

C．four

D．three
