Carbon monoxide(一氧化碳) poisoning kills and injures many people and animals around the world. The gas has been a problem since people first began burning fuels to cook food or to create heat. It is a problem in all parts of the world that experience cold weather.      Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color. It has no taste. It has no smell. It does not cause burning eyes. And it does not cause people to cough. But it is very deadly. It robs the body of its ability to use oxygen.      Carbon monoxide decreases the ability of the blood to carry oxygen to body tissues. It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it.      Damage to the body can begin very quickly from large amounts of carbon monoxide. How quickly this happens depends on the length of time a person is breathing the gas and the amount of the gas he or she breathes in.      Carbon monoxide poisoning has warning signs. But people have to be awake to recognize them. Small amounts of the gas will cause a person"s head to hurt. He or she may begin to feel tired. The person may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly. People develop severe head pain as the amount of gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomach pains.      Medical experts say carbon monoxide affects people differently. For example, a small child will experience health problems or die much quicker than an adult will. The general health of the person or his or her age can also be important. An older adult with health problems may suffer the effects of carbon monoxide more quickly than a younger person with no health problems. People with heart disease may suffer chest pains. They may begin to have trouble breathing.

Songs that make our hearts happy can make them stronger too, US researchers reported on Tuesday.They found that when people listened to their favorite music, their blood vessels (血管) dilated in much the same way as when they are laughing, or taking blood medications.      "We have a pretty impressive effect," said Dr Michael Miller, director of preventive cardiology (心脏病学) at the University of Maryland Medical Center in Baltimore.      "Blood vessel diameter improved," he said. "The vessel opened up pretty significantly. You can see the vessels opening up with other activities such as exercise." A similar effect is seen with drugs such as statins.      When blood vessels open up more, blood flows more smoothly and is less likely to form the clots (凝块) that cause heart attacks and strokes. "We are not saying to stop your statins or not to exercise but rather to add this to an overall program of heart health," said Miller, who presented his findings to a meeting of the American Heart Association in New Orleans.      Miller"s team tested 10 healthy, non-smoking men and women, who were told to bring their favorite music. They spent half an hour listening to the recordings and half an hour listening to music they said made them feel anxious while the researchers did ultrasound tests designed to show blood vessel function.      Compared to their normal baseline measurements, blood vessel diameter increased 26 percent on average when the volunteers heard their joyful music. Listening to music they disliked - in most cases in this group heavy metal - blood vessels narrowed by six percent, Miller said.      Miller said he came up with the idea after discovering that laughter caused blood to literally flow more smoothly. "I asked myself what other things make us feel really good, besides calories from dark chocolate of course. Music came to mind. ... It makes me feel really good," he said.      Most of the volunteers chose country music but Miller said the style is not so important rather than what pleases each individual.

TUVALU, a tiny country in the Pacific Ocean, has asked for help as it fears it will be swallowed up by the sea.     Storms and huge waves are a constant threat and none of Tuvalu"s nine little islands is more than five meters above sea leavel, Salt water is already entering the country"s drinking water supply, as wel l as damaging plants that produce fruit and vegetable. 1___________      2____  __. Venice, a historic city in Italy best known for its canals, has sunk about 24 cm over the past 100 years.   Experts say that it will have sunk another 20-50cm by 2050.           A century ago,   St. Mark"s Square, the lowest point in the city, flooded about nine times a year, Nowadays, it happens more that 100 times. While Venice is slowly sinking into the mud on which it stands, Tuvalu"s rising sea level is caused by global warming.      The average global temperature has increased by almost 0.5 centigrade degrees over the past century; scientists expect it to rise by extra 1-3 degrees over the next 100 years.      Warmer weather makes glaciers(冰川)melt, adding more water to the ocean.The warmer temperatures also make water expand, so it takes up more space, causing the sea level to rise. The sea level has risen    about 10－25 cm in the last 100 years.     3______. Through burning coal, oil and gas, people have been increasing the greenhouse gases in the  atmosphere, such as CO2. This adds to the power of the greenhouse effect, making the planet even warmer.Many scientists believe that, if the warming is not stopped, there will be huge climate changes. 4______5_______, the sea will swallow up millions of homes and the world will be flooded with "climate refugees" looking for somewhere to live.
A. The main cause of global warming is human pollution B. Should this come true C. Without urgent help, the country"s days are numbered. D. But Tuvalu is not the first place to face sinking into the sea E. The sea level could rise by one meter this century F. people face a lot of pollution G. much has been done about our planet

Hitting the bottle to help drown out memories you"d rather forget may in fact etch (铭刻) them more deeply into your consciousness, a new study has found.      And having one or two glasses of wine a day may increase your ability to remember, and even help with Alzheimer (老年痴呆症) sufferers. The study at Auckland University was undertaken by Dr. Maggie Kalev and Professor Mathew During.      The two researchers found moderate levels of alcohol consumption, equivalent to one or two glasses of wine a day, could augment memory.       In contrast, high levels of alcohol decreased the ability of new brain cells to develop and mature.      "Low levels of alcohol promoted neutral memories, such as remembering objects," said Dr. Kalev.      "However, contrary to popular belief, we also found that excessive levels of alcohol enhanced memories of highly emotional stimuli (刺激), meaning the concept of "drinking to forget" is unlikely to be true."      "Our work suggests that heavy drinking actually reinforces negative memories."      The study also identified the way low doses of alcohol improved memory.      Dr. Kalev said a "very important" brain receptor(受体), called an NMDA receptor, appeared to be necessary for the process.      Testing done on rats showed if they did not have enough NMDA receptors, their memory did not improve when given low alcohol doses.      However, rats which did show high numbers of NMDA receptors exhibited memory improvement when given small amounts of alcohol.      "Pathways  by which memory is laid down are unclear, but  NMDA  receptor is  critical  in  this process," Dr. Kalev said.      "Building on this knowledge may help in the treatment of memory disorders, such as Alzheimer"s disease and other dementias."       The results of the study are published in Journal of Neuroscience.
1. What is the best title of the passage?
A. The introduction of Alzheimer                   B. The good effect of alcohol C. The importance of NMDA receptor D. Moderate drinking can improve memory

A. Not low levels but excessive levels of alcohol increase memory. B. An NMDA receptor is the only factor for the process. C. According to the testing done on rats, their memory did not improve when given low alcohol doses if they did not have enough NMDA receptors. D. It is sure that the knowledge of the research can help to treat the memory disorders.
3. This article probably appears in ______.
A. a newspaper       B. science report       C. science fiction         D. a novel

These days a green building means more than just the color of the paint. Green building can also refer to environmentally friendly houses, factories, and offices.     Green building means "reducing the impact(影响)of the building on the land", Taryn Holowka of the U.S. Green Building Council in Washington, D. C., said.     According to Holoeka, building account for 65 percent of total U.S. electricity use.     Bur green building can reduce energy and water use. Also, the buildings are often located near public transportation such as buses and subways, ______________________________________.That could be good for the environment, because cars use lots of gas and give off pollution. Green buildings are often built on developed land, so that the buildings don"t destroy forest.    Marty Dettling is project manger for a building that put these ideas into action. The Solaire has been called the country"s first green high-rise building. According to Dettling, "We"ve reduced our energy use by one-third and our water by 50 percent."    The Solaire cuts energy in past by using solar power. "On the face of the building we have solar panels which change the sun"s energy into electricity, " Dettling explained.    The Solaria also has lights that automatically turn off when people leave the room. In addition, the building has lots of windows, allowing people to use the sun for light during the day. The Solaire cuts water reusing it.    Nor everyone is eager to move into a green building, however. Some people think that things like solar panels cost more money than more traditional energy sources. Anyhow, Holowka said, "It"s going to be big.
