Strangely,some people find that they can smell one type of flower but not another,( )others are sensitive to the smells of both flowers.

A.when
B.since
C.for
D.whereas

参考答案

参考解析
解析:本题考查的也是对空格前后的两个半句之间的逻辑关系的理解。由于上半句提到“有些人认为他们可以闻出一种花香,却闻不出另一种”,下半句提到“有些人却对两种花香都很敏感”。显然这两个半句之间构成一种对比关系,而选项A.when用于引导时间状语从语,B.since用于引导时间或原因状语从句,C.for用于引导原因状语从句,都不符合上下文语义关系。只有D.whereas可用于引导表示转折关系的并列句,符合上下文逻辑语义关系,因此,本题的正确选项是D

考题 The human nose is an underrated tool. Humans are often thought to be insensitive smellers compared with animals, __1__ this is largely because, __2__ animals, we stand upright. This means that our noses are __3__ to perceiving those smells which float through the air, __4__ the majority of smells which stick to surfaces. In fact, __5__, we are extremely sensitive to smells, __6__ we do not generally realize it. Our noses are capable of __7__ human smells even when these are __8__ to far below one part in one million.Strangely, some people find that they can smell one type of flower but not another, __9__ others are sensitive to the smells of both flowers. This may be because some people do not have the genes necessary to generate __10__ smell receptors in the nose. These receptors are the cells which sense smells and send __11__ to the brain. However, it has been found that even people insensitive to a certain smell __12__ can suddenly become sensitive to it when __13__ to it often enough.The explanation for insensitivity to smell seems to be that brain finds it __14__ to keep all smell receptors working all the time but can __15__ new receptors if necessary. This may __16__ explain why we are not usually sensitive to our own smells we simply do not need to be. We are not __17__ of the usual smell of our own house but we __18__ new smells when we visit someone else’s. The brain finds it best to keep smell receptors __19__ for unfamiliar and emergency signals __20__ the smell of smoke, which might indicate the danger of fire.1________________[A] although[B] as[C] but[D] while

考题 One can never find out what the other people think about from his facial expression. A、It means "wearing the mask"B、It means "keeping ideas to herself"C、It means "telling everyone her bright ideas"D、It means "agreeing with others’ ideas"

考题 Some people think no one can be ______ to SARS.A、freeB、ridC、openD、immune

考题 What type of constraint can be used to ensure that, in any given row in a table, the value of one column never exceeds the value of another column?() A.CheckB.RangeC.ReferentialD.Informational

考题 The process of perceiving others is rarely translated(to ourselves or others) into cold,objective terms."She was 5 feet 8 inches tall, had fair hair, and wore a colored skirt." More often, we try to get inside the other person to pinpoint his or her attitudes, emotions, motivations,abilities, ideas, and characters. Furthermore, we sometimes behave as if we can accomplish this difficult job very quickly--perhaps with a two-second glance. We try to obtain information about others in many ways. Berger suggests several methods for reducing uncertainties about others; who are known to you so you can compare the observed person's behavior with the known others' behavior, observing a person in a situation where social behavior is relatively unrestrained or where a wide variety of behavioral responses are called for,deliberately structuring the physical or social environment so as to observe the person's responses to specific stimuli, asking people who have had or have frequent contact with the person about himor her, and using various strategies in face-to-face interaction to uncover information about another person--question, self-disclosures, and so on. Getting to know someone is a never-ending task, largely because people are constantly changing and the methods we use to obtain information are often imprecise. You may have known someone for ten years and still know very little about him. If we accept the idea that we won't ever fully know another person, it enables us to deal more easily with those things that get in the way of accurate knowledge such as secrets and deceptions. It will also keep us from being too surprised or shocked by seemingly inconsistent behavior. Ironically, those things that keep us from knowing another person too well (e. g. secrets and deceptions) may be just as important to the development of a satisfying relationship as those things that enable us to obtain accurate knowledge about a person (e. g. disclosures and truthful statement). Some people are often surprised by what other people do. According to Berger, that is mainly because__________.A.some people are more emotional than others B.some people are not aware of the fact that we will never completely know another person C.some people are sensitive enough to sense the change of other people's attitudes D.some people choose to keep to themselves

考题 Primer on Smell In addition to bringing out1 the flavor of food, what does the sense of smell do for us ? Smell “gives us information about place, about where we are,” says Randall Reed, a Johns Hopkins University professor whose specialty is the sense of smell. ___1___ “Whether we realize it or not, we collect a lot of information about who is around us based on smell,” says Reed. Even at a distance, odors can warn us of2 trouble — spoiled food, leaking gas, or fire. “It’s a great alert,” offers Donald Leopold, a doctor at Johns Hopkins. For example, if something in the oven is burning, everyone in the house knows it. With just a simple scent, smell can also evoke very intense emotion. Let’s say, for example, that the smell is purple petunias. ___2___ Now let’s imagine that your mother died when you were three, and she used to have a flower garden. You wouldn’t need to identify the smell or to have conscious memories of your mother or her garden. You would feel sad as soon as you smelled that spicy odor. Compared with3 animals, how well do people detect smelts ? That depends on what you mean by “how well”. We are low on receptor cells : current estimates say that humans have roughly five million smell-receptor cells, about as many as a mouse. ___3___ Reed says that, across species, there is a relatively good correlation between the number of receptor cells and how strong the sense of smell is. “You can hardly find the olfactory bulb in a human brain —— it’s a pea-sized object. In a mouse, it’s a little bigger. It’s bean-sized in a rat, about the size of your little finger in a rabbit, and the size of your thumb in a bloodhound.” Does that mean that our sense of smell is not very acute ? Not exactly. While we may not have the olfactory range of other creatures, the receptors we do have are as sensitive as those of any animal. ___4___ A trained “nose”, such as that of a professional in the perfume business, can name and distinguish about 10,000 odors. Reed says that a perfume expert can sniff a modem scent that has a hundred different odorants in it, go into the lab, and list the ingredients. “In a modest amount of time, he comes back with what to you or me would smell like a perfect imitation of that perfume. It’s amazing.” What happens to4 our sense of smell as we age ? Many people continue to have good olfactory function as they get older. ___5___ Leopold says that smell is generally highest in childhood, stays the same from the teens through the 50s, and drops starting at about 60 for women and 65 for men. “The average 80-year-old is only able to smell things half as well as the average 20-year-old,” says Leopold. 词汇: scent /sent/ n. 气味,香味 petunia /p 'tju:ni / n. 喇叭花 olfactory / l'f kt( )ri/ adj. 嗔觉的,味道的 sniff /snif/ v. 嗅,闻,用力吸 注释: 1. bring out:使……显出,使……变得明显 2. warn of:发出关于……的警告。warn sb. of sth.:警告某人某事 3. compare with:与……相比 4. happen to:发生于,发生在 练习: A These flowers have a rich spiciness that no other petunia has. B Odors, or smells, can warn us about trouble. C That’s not the rule, however. D And smell tells us about people. E We can also think, and we make conscious (and successful) efforts to tell the difference between one smell and another. F A rat has some 10 million, a rabbit 20 million, and a bloodhound 100 million.

考题 资料: The poverty line is the minimum income that people need for an acceptable standard of living. People with incomes below the poverty line are considered poor. Economists study the causes of poverty in order to find solutions to the problem. As the general standard of living in the country rises, the poverty line does, too. Therefore, even with today’s relatively high standard of living, about 10 percent of the people in the United States are below the poverty line. However, if these people had stable jobs, they could have an acceptable standard of living. Economists suggest several reasons why poor people do not have jobs. For one thing, more than half of the poor people in the United States are not qualified to work. Over 40 percent of the poor. People are children. By law, children less than 16 years old cannot work in many industries. A large number of poor people are Old. Many companies do not hire people over 65 years old, the normal retirement age. Some poor adults do not look for jobs for a variety of personal reasons: they are sick, they do not have any motivation, they have family problems, or they do not believe that they can find a job. Other poor people look for a job but cannot find one. Many poor adults never went to high school. Therefore, when they look for jobs, they have few skills that they can offer. At the present time, the government thinks it can reduce poverty in the country in the following ways. First, if the national economy grows, businesses and industries hire more workers. Some of the poor who are qualified to look for jobs may find employment. Then they will no longer be below the poverty line. Second, if society invests in the poor, the poor will become more productive. If the government spends money on social programs, education, and training for poor people, the poor will have the skills to offer. Then it is more likely that they can find jobs. Finally, if the government distributes society's income differently, it raises some poor people above the poverty line. The government collects taxes from the non-poor and gives money to the poor. These payments to the poor are called welfare. In 1975 over 18 million people in the United States received welfare. Some economists are looking for better solutions to the poverty problem. However, at the present time, many people depend on welfare for a minimally acceptable standard of living. According to the passage, which of the following is NOT the reason of unemployment?A.some people are too young to work in many industries B.some people are satisfied with the government welfare C.some people don’t have motion to work D.some people are not qualified to work

考题 共用题干 Keeping Cut Flowers(鲜切花)1. While everybody enjoys fresh cut flowers around his/her house,few people know how to keep them for as long as possible .This may be done by keeping in mind a few simple facts.2. An important thing to remember about cut flowers is that they are sensitive to temperature.For example,studies have shown that cut carnations(康乃馨)retain their freshness eight times lon-ger when kept at 12℃than when kept at 26℃.Keeping freshly harvested flowers at the right tem-peratures is probably the most important aspect of flower care.3. Flowers are not intended by nature to live very long.Their biological purpose is simply to at-tract birds or insects,such as bees,for pollination(授粉).After that,they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide(二氧化碳), called respiration(呼吸),generates the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy.While all living things respire,flowers have a high level of respiration.A result of all this respiration is heat,and for flowers the level of heat relative to the mass of the flower is very high.Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration,the sooner the flower dies.4. How,then,to control the rate at which flowers die?By controlling respiration.How is respi-ration controlled?By controlling temperature .We know that respiration produces heat,but the re-verse(相反的过程)is also true. Thus by maintaining low temperatures , respiration is reduced and the cut flower will age more slowly.5. Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to“drink”water that is dirty or otherwise polluted.Even when water looks and smells clean,it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach(漂白剂)can be used in small quantities.It is recommended that 15 drops of chlorine bleach(at 4%solution)be add-ed to each litre of water. The water and solution should also be replaced each day. The aging of cut flowers can be slowed down________.A: by keeping its original shape and colorB: in the life of cut flowersC: to produce carbon dioxideD: for as long as possibleE: by controlling temperatureF: to replace the water and solution every day

考题 共用题干 第二篇Study Says Dogs Can Smell CancerDogs are known for their sense of smell.They can find missing people and things like bombs and illegal drugs.Now a study suggests that the animal known as man's best friend can even find bladder(膀胱)cancer.Cancer cells are thought to produce chemicals with unusual odors(气味). Researchers think dogs have the ability to smell these odors,even in very small amounts,in urine(尿).The sense of smell in dogs is thousands of times better than in humans.The study follows reports of cases where,for example,a dog showed great interest in a growth on the leg of its owner.The mole(痣)was later found to be skin cancer.Carolyn Willis led a team of researchers at Arnersham Hospital in England.They trained different kinds of dogs for the experiment.The study involved urine collected from biadder cancer patients,from people with other diseases and from healthy people.Each dog was tested eight times.In each test there were seven samples for the dogs to smell.The dog was supposed to signal the one from a bladder cancer patient by lying down next to it,Two cocker spaniels(短腿长毛垂耳小猎犬)were correct fifty-six percent of the time.But the scientists reported an average success rate of forty-one percent.As a group,the study found that the dogs chose the correct sample twenty-two out of fifty-four times.That is almost three times more often than would be expected by chance alone.The British Medical Journal published the research.In all,thirty-six bladder cancer patients and one hundred and eight other people took part.During training,all the dogs reportedly even identified a cancer in a person who had tested healthy before the study,Doctors found a growth on the person's right kidney(肾).Bladder cancer is the ninth most common cancer worldwide.The International Agency for Research on Cancer says this disease kills more than one hundred thousand people each year.Doctors say cigarette smoking is the leading cause of bladder cancer.
