高三英语单项填空简单题查看答案及解析

We like to think that the human mind is special. One sign of our superiority is self-awareness, which is generally seen as the peak of consciousness. Only a select group of species has passed the test of being able to recognise themselves in a mirror. Most, including elephants, apes and dolphins, are smart. But now a little fish, the cleaner wrasse has become the first fish ever to pass the mirror test——a classic experiment used to judge self-awareness in animals. What are we to make of this?

Admittedly^ the mirror test is a questionable way of probing （探究）the minds of other animals. But the finding does fit with a new idea that the ability to recognise oneself is more related to an animal’s　 lifestyle than to its brain size. Self-awareness is likely to occur in creatures whose survival is dependent on reading the minds of others. In fact, by this way of thinking, it is nothing more than an accidental by-product of evolution^ a simulation （模拟）created by the brain, or even just a hall of mirrors giving the illusion of complexity.

The cleaner wrasse lives on coral reefs and provides a service by biting parasites （寄 生虫）off the scales of bigger fish gently, a delicate relationship that may require insight into the minds of its clients. Such “theory of mind” has long been seen as another cornerstone of human mental superiority. The possibility that fish possess it is not, however, the only threat to our human exceptionalism （例外）.It may not be long before computers give us a run for our money , too.

Researchers have created a set of tests to look for theory of mind in artificial intelligence— and some systems are on the point of passing. No AIs have passed the tests yet, but one got extremely close. We probably don't need to worry about robots that can recognise themselves in mirrors. But we might want to be more open to the idea that human intelligence isn't quite as special as we like to think.

1.What can we learn from the mirror test?

A.Mammals have a more adaptive body system.

B.A species of fish is capable of self-recognition.

C.The human mind is just as special as expected.

D.Humans have reached the peak of consciousness.

2.According to the passage, self-awareness　 .

A.is formed during evolution by chance B.corresponds with the size of the brain

C.isn't a hall of mirrors but a simulation D.reflects the typical mental complexity

3.The underlined part in Paragraph 3 probably means "

A.bring us huge profits

B.cost us a lot of money

C.have great control over us

D.challenge our exceptionalism

4.What' s the main idea of the passage?

A.Fish possess no level of intelligence.

B.Humans are not unique in intelligence.

C.AIs will be able to understand our thoughts.

D.Self-awareness is a big mystery of the mind.

Everybody knows that Coca-Cola is red, and Starbucks is green. 1. What we may not be aware of is the science behind these companies’ choices of these colors.

Color psychology is the study of how colors affect people’s mood, behavior, and decision-making. Companies use color psychology when they develop their brands and advertisements in order to persuade us to buy.2.

3. For example, it’s no accident that many tech products use white; it’s simple, stylish, and clean. Meanwhile, cosmetics companies tend to go for purple, black, or pink colors that represent passion, luxury, and romance.

Companies often choose action colors that urge you to buy right now. Red, for instance, is a high-energy, exciting color that moves people to action. Yellow is the color of summer, and it’s bright and attention-grabbing.4.

5. Studies show that consumers prefer brands that they recognize. Thus, those with an established color scheme, such as LEGO or Facebook, are likely to perform more strongly on the market.

All this goes to show that successful companies have mastered the art of color psychology. It may seem trivial, but their choice of colors has a profound effect on the spending habits of consumers.

A .Based on this, companies create fancy names for colors to make them sound special.

B. In fact, studies have shown that around 90 percent of people base their spending choices on color and appearance.

C. It’s no wonder that McDonald’s decided to use these two colors for its branding.

D. Chances are that most of us can name companies and their respective brand colors.

E. In fact, most major companies are associated with certain specific colors.

F. Because of this, companies use colors to influence how we feel about their products.

G. This is why, for example, Estée Lauder uses names like “passion fruit” and “hot rocket” for its lipsticks.

Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn’t it?

　While such vigilant(警觉的)tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it’s important to weigh the health benefits of screening against the risks and costs of routine testing.

　In many cases, screening can lead to additional biopsies and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients’ remaining years. But the message that everyone must screen for cancer has become so ingrained that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.

　It’s hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(预期寿命).

　A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening- especially considering the explosion of the elderly that will soon swell our population.

　It’s not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational use of health care and stop talking about the rationing of health care.”

　That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.

1.Why do doctors recommend routine cancer screening for elderly people?

A. It is believed to contribute to long life.

B. It is part of their health care package.

C. The elderly are more sensitive about their health.

D. The elderly are in greater danger of tumor growth.

2.How do some researchers now look at routine cancer screening for the elderly?

A. It adds too much to their medical bills.

B. It helps increase their life expectancy.

C. They are doubtful about necessity.

D. They think it does more than good.

3.What is the conventional view about women screening for breast cancer?

A. It applies to women over 50.

B. It is a must for adult women.

C. It is optional for young women.

D. It doesn’t apply to women over 74.

4.Why do many doctors prescribe routine screening for cancer?

A. They want to protect themselves against medical disputes.

B. They want to take advantage of the medical care system.

C. They want data for medical research.

D. They want their patients to suffer less.

5.What does the author say is the general view about health care?

A. The more, the better.

B. Prevention is better than cure.

C. Better early than late.

D. Better care, longer life.
