2014高考英语阅读理解基础精品训练题（114）及答案阅读理解----------BAlzheimer's disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchersand doctors have been studying Alzheimer's patients for a century. Yet the cause and cure for the mental sickness are still unknown. However, some researchers have madeimportant steps towards understanding it.Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children.There are also some physical tests that might show who is at risk of developingAlzheimer's disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein testscorrectly identify the presence of the disease in about ninety percent of patients.Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signsof Alzheimer's. Using this information, they developed a test in which people wereasked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke.The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percentof those who could not identify at least four of the smells in the first test hadtrouble with their memory and thinking in the next five years.Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read anewspaper, or play chess or word games are about three times less likely to developthe condition.Researchers say they still do not know what causes Alzheimer's disease. But theysay these findings might help prevent the disease in the future.6. What’s the main idea of the passage?A. Some early signs of the Alzheimer's disease.B.

CWhen I met him, I had a lot of anger inside of me. I’ve lived my whole life in Spanish Harlem, but in my neighborhood, there are shoot-ups all the time. I know kids who have been shot or beaten up. I have friends who ended up in prison. I could haveended up that way, too, but Mr. Clark wouldn’t let that happen.Mr. Clark worked long hours, making sure I did my work. My grades rose. In fact,the scores of our whole class rose. One day, he took our class to see The Phantom of the Opera, and it was the first time some kids had ever been out of Harlem. Beforethe show, he treated us to dinner at a restaurant and taught us not to talk with ourmouths full. We did not want to let him down.Mr. Clark was selected as Disney’s 2000 Teacher of the Year. He said he woulddraw three names out of a hat; those students would go with him to Los Angeles toget the award. But when the time came to draw names, Mr. Clark said, “You’re all going.”　On graduation day, there were a lot of tears. We didn’t want his class to end.In 2001, he moved to Atlanta, but he always kept in touch. He started giving lectures about education, and wrote a bestselling book based on his classroom rules, The Essential 55.In 2003, Mr. Clark took some of us on a trip to South Africa to deliver schoolsupplies and visit the orphanages (孤儿院).

Perhaps yes. Scientists have found the gene that determines skin color.The gene comes in two versions, one of which is found in 99 per cent of Europeans.The other is found in 93 to 100 per cent of Africans, researchers at PennsylvaniaState University report in the latest issue of Science.Scientists have changed the color of a dark-striped zebrafish（斑马鱼） to uniform gold by inserting a version of the pigment (色素) gene into a young fish. As with humans, zebrafish skin color is determined by pigment cells, which contain melanin(黑色素). The number, size and darkness of melanin per pigment cell determine skincolor.It appears that, like the golden zebrafish, light-skinned Europeans also havea mutation (变异) in the gene for melanin production. This results in less pigmentedskin.However, Keith Cheng, leader of the research team, points out that the mutationis different in human and zebrafish genes.Humans a cquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun (太阳光紫外线), which can cause skin cancer.But when modern humans leave Africa to live in northern latitudes, they need moresunlight on their skin to produce vitamin D. So the related gene changes, accordingto Cheng.Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, saidCheng.The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color without damaging it like chemicaltreatment did on Michael Jackson.16. The passage mainly tells us that ________.A. people can not change their skin color without any painB. the new discovery could lead to research into ways to change skin color safelyC. pop king Michael Jackson often changed his skin color as he likedD. scientists have found out that people’s skin color is determined by the gene17. It can be inferred from the passage that ________.A. nowadays people who want to change their skin color have to suffer a lot fromthe damage caused by the chemical treatmentB. Europeans and Africans have the same geneC. the new discovery could help to find medical treatments for skin cancerD. there are two kinds of genes18. Scientists have done an experiment on a dark-striped zebrafish in order to________.A. find the different genes of humans’B. prove the humans’ skin color is determined by the pigment geneC. find out the reason why the Africans’ skin color is darkD. find out the ways of changing people’s skin c olor19. The reason why Europeans are light-skinned is probably that _____A. they are born light-skinned peopleB. light-skinned Europeans have mutation in the gene for melanin productionC. they have fewer activities outsideD. they pay much attention to protecting their skin20. The writer’s attitude towards the discovery is ________.A. neutral（中立的）B. negativeC. positiveD. indifferent（冷漠）【参考答案】16—20、DABBC阅读理解-----------CSlang is a popular, less official and often very current form of language. It isan important part of a living language and is constantly changing as language changes. Slang is often playful, direct and sometimes less respectful than the more officialand traditional version of language. So now I'm going to lay it on you! To “lay it on” is American slang for “to tell” or “to explain.”Slang can take many forms. For example, slang can be local to one city or area.In Washington, D.C. there is a whole set of slang to describe politics and businessin the city. For example, the term POTUS stands for President of the United States.POTUS c an often be found with his wife, FLOTUS, the first lady of the United States. “Inside the Beltway” is a popular expression that describes the area of Washington, D.C. The beltway is the large highway that circles the city.The Internet has helped create a whole new kind of computer-related slang. An“angry fruit salad”　is an expression that describes a Web s ite with too many bright colors. “Netiquette” is slang for correct behavior when using the Internet.Young people often develop the latest slang. For example, to say Special English“rocks” or is “phat” means Special English is really great. A “kegger” is aparty where beer is served. If something is “wack” it is wild and crazy.Different professions often have their own slang as well. For example, medicalworkers might ref er to a complaining patient as a “gomer”． A "tough stick" is someone whose veins are difficult to find when he or she needs to have blood taken.No matter how well you speak English, there are always new and interesting slangwords to discover. There are entire dictionaries for describing slang. Many expertsdo not even agree on what is and what is not slang. Often slang words later becomea part of officially accepted language.
