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 persons 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 pains as the amount of the 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.1Why is carbon monoxide called the silent killer? ABecause it tastes and smells good. BBecause it is not easily noticed. CBecause it kills and injures people. DBecause it always harms people.答案：B推理判断题。由文章第二段内容可知，一氧化碳无色、无味、不刺激眼睛，也不会让人咳嗽，也就是说它不容易被人发觉。故选B。2How does carbon monoxide harm people? AIt makes peoples blood unable to move. BIt decreases the amount of blood in the body. CIt makes body tissues full of blood. DIt makes the blood less able to carry oxygen.答案：D细节理解题。由第三段第一句可知，一氧化碳伤害人体的方式是：降低血液携带氧气的能力。3When people breathe in small amounts of carbon monoxide, they may _. Afeel a little dizzy Bsuffer a severe headache Cgo around in the room Dhave a terrible stomachache答案：A推理判断题。倒数第二段向我们描述了人体吸入一氧化碳后的反应：吸入少量时，会头疼，感觉恶心，会觉得房子在转动，不能清晰地思考。A项所说的“feel a little dizzy”对应“The room may appear to be turning around.”。4Which of the following about carbon monoxide poisoning is TRUE? AAdults are affected more seriously than children. BYoung people are more severely affected than old people. CPeople in poor health may have severer consequences. DPeople with heart problems only suffer from chest pains.答案：C细节理解题。最后一段讲述了不同的人吸入一氧化碳后的不同反应：儿童比成年人所受的影响大；老人及身体健康状况欠佳的人比年轻及身体健康的人所受的影响会更大。D项干扰性最大，但是原文的用词是“may suffer chest pains”，说明患有心脏疾病的人除一氧化碳中毒的症状之外，还可能会出现胸痛、呼吸困难等反应。BEvery ocean lover knows the dangers of getting caught in a rip current (离岸流). Experienced swimmers know it is relatively easy to escape the narrow channel of the fast moving water by floating and allowing it to drag you further into the ocean or by swimming alongside the shore. However, inexperienced beachgoers often panic, and try to swim to land, placing themselves at risk of drowning due to tiredness. According to the US National Ocean Service, the currents kill about 100 Americans each year and account for 80% of all lifeguard rescues. These scary statistics may soon be a thing of the past, thanks to Clever Girl, a smart buoy (浮标) that warns swimmers of the presence of deadly rip currents.The smart device is the brainchild of Australian teenager Maddison King, who created Clever Girl as a project for her Grade 12 Design and Technology class. The 18yearold, who works as a lifeguard during her spare time, came up with the brilliant idea after discovering that most children were unable to detect rip currents.The basketballsized plastic buoy, which can be attached to a chain of similar devices or the ocean floor, is fitted with a small propeller (螺旋桨). When the water travels at the speed of over 70 centimeters per second, it spins the propeller fast enough to power the light atop the buoy, warning swimmers to stay clear of the area.Though it sounds simple enough, the youngster had to overcome numerous design challenges. For instance, she picked a red light since it is easy to see in the bright sunlight and also because the color serves as a universal warning sign for tourists that do not speak the local language. The devices smooth surface and high handles ensure swimmers do not get hurt, while the black, white, and red striped underside, keeps sharks and other animals at bay.Future versions might include something like a warning siren, which would provide sound warnings of rip currents. Besides, the present model costs about $300 to make. “Thats beyond my purse，” she laughs, “the cost has to be cut down.”5Which of the following is the right way to escape the rip current?AWaiting for rescues.BSwimming to the shore.CMoving
