四川省广安友实学校2023-2024学年高二下学期6月月考英语试题

 阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

Steager is an engineer at the University of Pennsylvania. His colleague Hyun Koo is an inventor and dental researcher there. Together, they found a way to form the nanoparticles(纳米颗粒)into long, skinny bristles(鬃毛), a lot like the ones on a toothbrush. But these bristles shape-shift to fit whatever surface they encounter. They can even squeeze between teeth.

"A new way to clean teeth could help out anyone who finds this chore boring," says Koo. But it would be especially life-changing for people with disabilities or illnesses that make it difficult or impossible to hold and move a toothbrush.

The tooth-cleaning robot works thanks to two magnets(磁铁). One goes on each side of the teeth. The nanoparticles sit in a water-based solution between the magnets. When the magnets are turned off, the nanoparticles float randomly in the solution. As soon as one magnet gets turned on, the nanoparticles clump together near its center. When you turn on the other magnet and turn off the first one, the nanoparticles extend outward in long, skinny bristles.

When there's a tooth in the way, these bristles can't stretch out as far as they want. So they push against the tooth's surface. If there's a gap between teeth, they push into the gap. Moving the magnets makes the bristles move against and between teeth.

Besides, as a bonus, the nanoparticles can kill what harms the teeth and keep them health y because it contains something commonly added to toothpaste and mouthwash.

The new invention is just a proof of concept. The researchers still need to turn it into a product that people will want to use. It must fit comfortably and safely in people's mouths. It can't draw too much power or cost too much. "There's a lot of engineering to get from here to there," says Steager. But he adds, "every good idea needs to have a start."

(1)、What is a feature of the bristles?
A、They can be solved into water. B、They can change shapes. C、They only work in liquid. D、They feel much softer.
(2)、What aspect of the invention is mainly talked about in paragraph 3?
A、Its shape. B、Its function. C、Its structure. D、Its working principle.
(3)、What does the underlined word "clump" mean in paragraph 3?
A、Subscribe. B、Drag. C、Gather. D、Remove.
(4)、What can we infer from Stager's words?
A、The invention still needs them to put more efforts. B、The first step is always the hardest. C、Engineering can be applied to every field. D、A good beginning is half done.

    Safety in the highway is not totally out of our hands. Here are four ways we can protect ourselves when we travel.

    {#blank#}2{#/blank#} people in small cars are injured more often and more severely than people traveling in large cars. Factories of small cars are strengthening their products' safety, which helps. But the mix of large cars and small cars on the road is the main reason of the problem.

    Being thrown into glass and mental cars parts, or being thrown from the car can really hurt or even kill you.

    {#blank#}3{#/blank#}The safety belt's main purpose is to pull you back if your car has a sudden crash with another vehicle or object, or if it rolls over. A belt can reduce the chance of deadly injury by 45% and the chance of serious injury by 50%.

    Air bags are important. More than half of all new cars sold have air bags. Air bags provide protection in frontal crashes—the type of crash that kills the most drivers—when they are also wearing safety belts. Most people are demanding air bags in the cars they buy.  {#blank#}4{#/blank#} Effective as they are, they can't take the place of safety belts.

    Drunk driving crashes are less likely to happen if you don't drink. {#blank#}5{#/blank#}Many people have realised that drunk driving can lead to death and injury, prison time and other results. There are movements to strengthen penalties(处罚) for drinking and driving.

A. How to drive safely?

B. You are safer in a large car

C. How to protect ourselves in the highway?

D. Air bags are not installed in all cars.

E. That's why safety belts should be worn.

F. Drunk driving is the most serious problem.

G. But the protection provided by air bags is limited in side or rear crashes.

    People who often eat nuts appear to live longer, according to the latest study of its kind. The findings, published in the New England Journal of Medicine, suggested the greatest benefit was in those eating them on their daily diet.

    Eating nuts was linked to a healthier lifestyle including being less likely to smoke or be overweight and more likely to exercise. The British Heart Foundation said more research was needed to prove the link, “While this is an interesting link, we need further research to make sure if it's the nuts that protect heart health, or other sides of people's lifestyle .”

    The study followed nearly 120,000 people for 30 years. The more regularly people ate nuts, the less likely they were to die during the study. People eating nuts once a week were 11% less likely to have died during the study than those who never ate nuts. Lead researcher Dr. Charles Fuchs, from the Dana-Farber Cancer Institute and Brigham and Women's Hospital, said, “The most obvious benefit was a decrease of 29%in deaths from heart disease, but we also saw a significant reduction-11%- in the danger of dying from cancer.”

    They suggest nuts are lowering cholesterol(胆固醇). and insulin resistance(胰岛素抗性). Nuts contain unsaturated fat(不饱和脂肪), protein(蛋白质) and several kinds of vitamins and minerals and they can take the place of snacks like chocolate bars, cakes and biscuits.

    Victoria Taylor, senior expert at the British Heart Foundation, said, “This study shows close connection between regularly eating a small handful of nuts and a lower risk of death from heart disease.” Choosing plain, unsalted foods rather than sweet, salted, or chocolate-covered will keep your salt and sugar intake down.

    I grew up in a house where the TV was seldom turned on and with one wall in my bedroom entirely lined with bookshelves,most of my childhood was spent on books I could get hold of. In fact,I grew up thinking of reading as natural as breathing and books unbelievably powerful in shaping perspectives (观点) by creating worlds we could step into,take part in and live in.

    With this unshakable belief,I,at fourteen,decided to become a writer. Here too,reading became useful. Every writer starts off knowing that he has something to say,but being unable to find the right ways to say it. He has to find his own voice by reading widely and discovering which parts of the writers he agrees or disagrees with,or agrees with so strongly that it reshapes his own world. He cannot write without loving to read,because only through reading other people's writing can one discover what works,what doesn't and, in the end,together with lots of practice,what voice he has.

    Now I am in college,and have come to realize how important it is to read fiction (文学作品).As a law student,my reading is in fact limited to subject matter — the volume (量) of what I have to read for classes every week means there is little time to read anything else. Such reading made it all the clearer to me that I live in a very small part in this great place called life. Reading fiction reminds me that there is life beyond my own. It allows me to travel across the high seas and along the Silk Road,all from the comfort of my own armchair,to experience,though secondhand,exciting experiences that I wouldn't necessarily be able to have in my lifetime.

    Drug companies have spent billions of dollars searching for therapies to reverse or significantly slow Alzheimer's disease, but in vain. Some researchers argue that the best way to make progress is to create better animal models for research, and several teams are now developing mice that more closely imitate how the disease destroys people's brains.

    The US National Institutes of Health (NIH), the UK Dementia Research Institute and Jackson Laboratory (JAX) - one of the world's biggest suppliers of lab mice - are among the groups trying to genetically design more suitable mice. Scientists are also exploring the complex web of mutations(突变) that influences neurological (神经学的) decline in mice and people.

    "We appreciate that the models we had were insufficient. I think it's sort of at a critical moment right now." says Bruce Lamb, a neuro-scientist at Indiana University ~ho directs the NIH-funded programme.

    Alzheimer's is marked by cognitive impairment(认知损伤) and the build-up of amyloid-protein plaques (淀粉样蛋白块) in the brains of people, but the disease does not occur naturally in mice. Scientists get around this by studying mice that have been genetically modified to produce high levels of human amyloid protein. These mice develop plaques in their brains, but they still do not display the memory problems seen in people.

    Many experimental drugs that have successfully removed plaques from mouse brains have not lessened the symptoms of Alzheimer's disease in people. One focused stumble came last month, when three companies reported that their Alzheimer's drugs had failed in large, late-stage clinical trials. Although the drugs successfully blocked the accumulation of amyloid protein in mice, they seemed to worsen cognitive decline and brain shrinkage in people.

    The drive for better mouse models comes as genomics studies are linking the most common form of Alzheimer's to dozens of different genes. This diversity suggests that each case of the disease is caused by a different combination of genetic and environmental factors. "There is no single Alzheimer's disease," says Gareth Howell, a neuro-scientist at Jackson Laboratory (JAX) in Bar Harbor, Maine.

    Howell argues that scientists' reliance on lab mice with only a few genetically engineered mutations might have limited research. His own work suggests that in mice, just as in people, genetic diversity plays a part in determining how Alzheimer's develops.

请认真阅读下列短文,从短文后各题所给的A、B、C、D四个选项中,选出最佳选项。

    Our society is generally becoming one of giant enterprises directed by a bureaucratic management in which man becomes a small, well-oiled cog in the machinery. The oiling is done with higher wages, Nell-ventilated factories and piped music, and by psychologists and "human-relations" experts; yet all this oiling does not alter the fact that man has become powerless, that he is bored with it. In fact, the blue and the white-collar workers have become economic puppets who dance to the tune of automated machines and bureaucratic management.

    The worker and employee are anxious, not only because they might find themselves out of a job; they are anxious also because they are unable to acquire any real satisfaction of interesting life. They live and die without ever having confronted the fundamental realities of human existence as emotionally and intellectually independent and productive human beings.

    Those higher up on the social ladder are no less anxious. Their lives are no less empty than those of their subordinates. They are even more insecure in some respects. They are in a highly competitive race. To be promoted or to fall behind is not a matter of salary but even more a matter of self-respect. When they apply for their first job, they are tested for intelligence as well as for the right mixture of obedience and independence. From the moment on they are tested again and again—by the psychologists, for whom testing is a big business, and by their superiors, who judge their behavior, sociability, capacity to get along, etc. This constant need to prove that one is as good as or better than one's fellow competitor creates constant anxiety and stress, the very causes of unhappiness and illness.

    Am I suggesting that we should return to the preindustrial mode of production or to nineteenth-century "free enterprise" capitalism? Certainly not. Problems are never solved by returning to a stage which one has already outgrown. I suggest transforming our social system form a bureaucratically managed industrialism in which maximal production and consumption ends in a humanist industrialism in which man and full development of his potentialities – those of all love and of reason—are the aims of social arrangements. Production and consumption should serve only as means to this end, and should be prevented from ruling man.

    Positive thinking is a significant element of happiness. In order to become a positive thinker, determination and consistency are important. The first thing to know about positive thinking is that everyone can do it.  With certain cognitive (认知的) and behavioral changes, we can all become positive thinkers. Another important factor is that being a positive thinker does not mean you become numb to anything that is not working properly in your life or is negative - it just means that you approach life and face challenges with a healthier outlook.

    Instead of selectively attending to negative events, focus on the positive ones. Then pay attention to the delayed consequences of your behavior rather than the immediate ones. For example, if a job is not going like you want, focus on the fact that you have a job and how you can take your time to make the situation better.

    Challenge any internal attributions and see if you compare your behavior to standards that are excessively rigid and perfectionistic. If so, change these and be reasonable with your comparisons. For example, if you constantly compare your weaknesses with other people's strengths, then switch this and compare yourself with those who are doing poorer than you as well. Overall, people who focus more on their strengths than their weaknesses but at the same time are aware of their weaknesses have a healthier self-evaluation result.

    When faced with too much fear about a situation, imagine the worst case and visualize a solution for it, then let go of fear. This way, you will be prepared for anything and your fear will not block you from being open and creative to different solutions. For example, if you are constantly worried about losing your job up to a point where it is creating a lot of anxiety and fear and is effecting your performance and your happiness negatively, then think of losing your job, visualize how you will handle it, find solutions in your mind and then let go of the thought and the fear attached to it.

    So positive thinkers are better problem solvers and have better interactions. In addition to that, people who are positive thinkers are happier and more satisfied with their life.
