2、The Hurricane1. A hurricane (飓风) is a tropical storm with winds that have reached a constant speed of 74 miles per hour. Hurricane winds blow in a large spiral(螺旋) around a relative calm center known as the "eye". The "eye" is generally 20 to 30 miles wide, and the storm may extend outward 400 miles. As a hurricane nears land, it can bring heavy rains, high winds and storm surges(风暴潮). The storm surges and heavy rains can lead to flooding.2. Hurricanes are given a different label, depending on where they occur. If they begin over the North Atlantic Ocean, the Caribbean Sea, The Gulf of Mexico, orthe Northeast Pacific Ocean, they are called hurricanes. Similar storms that occur in the Northwest Pacific Ocean west of the Internaional Date Line are called typhoons near Australia and in the Indian Ocean, they are referred to as tropical cyclones(龙卷风).3. When a hurricane hits land, it can do great damage through its fierce winds, heavy rains, inland(内陆的) flooding and huge waves crashing on to the shore. During a hurricane, homes, businesses and public buildings may be damaged ordestroyed, roads and bridges can be washed away. A powerful hurricane can kill more people and destroy more property than any other natural disaster. Fishermen are at special risk from hurricanes as they may be at sea when a hurricane arrives and not be able to get to a safe harborif they do not receive adequate warning.4. If a hurricane is comming in your area, the most important thing is to stay calm and find shelter immediately. Go to your safe room. If you do not have one, stay indoors during the hurricane and go to a safer place near the center of your home. Cover yourself with a blanket and be sure to keep away from windows and glass doors, because if the glass breaks it’s really dangerous. Do not be fooled if there is lull(暂停), it could be the eye of the storm—winds will pick up again.Depending on where they occur, hurricanes have ______.【单选题】
A.different labels
B.window and glass doors
C.inland flooding
D.early warning
E.natural disaster
F.a constant speed
正确答案:A
答案解析:本题难度不大,答案依据比较明显,在文章第二段的第一句:Hurricanes are given a different label,depending on where they occur.回来看选项,A项符合原文句意,是答案。
3、One Good Reason to Let Smallpox LiveIt\'s now a fair bet that we will never see the total extinction (灭绝) of the smallpox (天花) virus. When smallpox was completely got rid of in the world, scientists wanted to destroy the killer virus in the last two labs, one in the US and one in Russia. They asked: If smallpox has truly gone from the planet, what point was there in keeping these reserves?In reality, of course, it was naive to imagine that everyone would let go of such a powerful potential weapon. Undoubtedly several nations still have a few vials (小药瓶). and the last "official" stocks of live Virus bred mistrust of the US and Russia, forno obvious gain.Now American researchers have found an animal model of the human disease, opening the way fortests on new treatments and vaccines(疫苗). So once again there\'s a good reason to the virus, just in keep the disease puts in a reappearance.How do we case with the mistrust of the US and Russia? deal. Keep the virus Simple international support in a well - guarded UN laboratory that\'s open to all countries. The US will object, of course, just as it with a multilateral (多边的) approach to just about everything. But it doesn\'t mean the idea is _____. If the virus is useful, then let\'s wrong it the servant of all humanity make not just a part of it.【单选题】
A.adopts
B.rejects
C.suggests
D.introduces
正确答案:B
答案解析:本题有一定难度,考查词义辨析。本题可以借助语法知识来确定答案。句子的前后两部分用as连接,表明前后两句话的意思相近,前半句中出现object 一词,那么后面应用object的近义词,都是“反对”的意思,答案是B。
4、Radiocarbon DatingNowadays scientists can answer many questions about the past through a technique called radiocarbon (放射性碳), orcarbon - 14 dating. One key to understanding how and why something happened is to discover when it happened.Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon -12, has six protons (质子) and six neutrons (中子) in its nucleus (原子核). Carbon - 14, orC - 14, is a radioactive, unstable form of carbon that has two extra neutrons. It returns to a more stable form of carbon through a process called decay (衰减). This process involves the loss of the extra neutrons and energy from the nucleus.In Libby\'s radiocarbon dating technique, the weak radioactive emissions(放射)from this decay process are counted by instruments such as a radiation detectorand counter. The decay rate is used to determine the proportion of C -14 atoms in the sample being dated.Carbon - 14 is produced in the Earth\'s atmosphere when nitrogen(氮) - 14, orN - 14, interacts with cosmic rays (宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C -14 formation is thought to occur at a constant rate. Now the ratio of C -14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful fordating items back to at least 50,000 years.All life on Earth is made of organic molecules (分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C -14 atoms to other carbon atoms in their tissues (组织). Once an organism (有机体) dies it stops taking in carbon in any form, and the C -14 already present begins to decay. Over time the amount of C - 14 in the material decreases and the ratio of C - 14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C -14 atoms in a sample, the older that sample is.Nowadays many scientists depend on radiocarbon fordating age - old objects.【单选题】
A.Right
B.Wrong
C.Not mentioned
正确答案:A
答案解析:本题难度不大,答案依据比较明显,主要答案依据在文章第一段第一段:Now-adays scientists can answer many questions about the past through a technique called radiocarbon,orcarbon - 14 dating,谈到现在科学家可以通过一种叫做放射性碳定年法来解读过去,题干是其近义解释,所以正确,答案是A。
5、The book took ten years of thorough research.【单选题】
A.basic
B.careful
C.social
D.major
正确答案:B
答案解析:这本书花了十年时间的精心研究。本题难度不大,干扰项干扰不大,是送分题,thorough的引申意义指“认真的,精心的”,careful是“认真的”意思,所以最佳答案是B。
