四川省乐山市沫若中学2019届高三上学期英语(9月)入学考试试卷

阅读短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

    Scientists around the world are striving for effective detection of cancer in the early stages, which is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body, and a Chinese scientist may have found a quick way of knowing whether malignant tumors (恶性肿瘤) exist in a patient's body, with just one drop of blood.

    Malignant tumors in early phases can be cured. However, it's extremely difficult to be aware of cancer in its early stages, as patients don't show obvious symptoms and thus it can only be found in its later stages, which is already too late, so to detect cancer early remains a global challenge for scientists.

    Back in 1989, scientists have found a kind of heat shock proteins (HSP), named Hsp90α, which existed in human bodies and can be used as a cancer biomarker detection kit. Scientists around the globe have been working on it since then, and more than 10, 000 journals have been published on accredited magazines, yet no one has actually turned their research results into medical products.

    However, Luo Yongzhang and his team in Tsinghua University's School of Life Sciences in Beijing seemed to have cracked the code, after working on the problem since 2009.The team has produced an artificial Hsp90α protein for clinical use that gains structural stability by regrouping proteins. The test kit can diagnose multiple kinds of cancer by analyzing a drop of human blood. This means they are able to "create" the protein, in any quantity, and at any time they wish to.

    The kit has since been used in clinical trials involving 2, 347 patients at eight hospitals in China. It was the first clinical trial in the world to test if the protein could be a useful tumor biomarker for lung cancer, and it succeeded. Now, the kit has been approved to enter the Chinese and European markets, 24 years after Hsp90α was discovered.

(1)、Why is cancer hard to cure?
A、Malignant tumors are found too late. B、Malignant tumors spread too quickly. C、Its symptoms are shown in early stages. D、No proper treatment can be applied to it.
(2)、What do we learn about Hsp90α from Paragraph 3?
A、It was created by scientists in 1989. B、All magazines have covered the topic. C、There has been a medical product about it. D、It can serve as a cancer detection approach.
(3)、How does the Chinese kit diagnose cancer?
A、By regrouping proteins. B、By cracking cancer's code. C、By breaking down one drop of blood. D、By producing an artificial Hsp90α protein.
(4)、It can be inferred that a European with lung cancer in early phases ________.
A、can't be cured in the end B、can be diagnosed with it in time C、has to be examined in China D、expects the kit to come into the market

    A new family moved in next door and I got to meet the mother of the family, Lydia. Lydia is Korean, and her family moved to our city so her husband could go to graduate school. We started talking, and she was apologetic about how bad her English was, but I didn't care. I knew how hard it was to learn a second language. I enjoyed chatting with Lydia as we watched our kids play.

    It was what came next that challenged me: Lydia asked if I'd be willing to help her with her English. Now, I am not a teacher. I admire teachers, and I'm grateful for teachers, and it's because I admire what they do so much that I was very very sure that I couldn't do it myself.

    But Lydia was sure that she wanted my help. I was doubtful. I wasn't sure my "help" was even worth being called by that name. But because she asked me, I said "yes." And that was the beginning of a friendship. Lydia and I spent afternoons sitting together and reading the newspaper, and as we did, she asked me questions when she had them questions about language, yes, but also questions about the new culture she found herself in. In turn, I asked my own questions, growing curious about her home country and culture. We bonded over our shared faith and our struggles as mothers of kids with special needs, When I complimented(恭维) her cooking, she began to teach me about Korean food, eventually leading to a shared trip to explore the Korean grocery stores in our city. Because of Lydia, 1 learned more about my own hometown than I ever could have learned by myself. I'm still not sure that I'm any good as a teacher. But I'm grateful I said "yes" when my neighbor asked me to help her with her English. That meant spending extra time with my neighbor, and that extra time meant she didn't remain just my neighbor. She became my friend.

    A recent study surveyed 5,000 British families about their experiences with volunteering and their mental health. Participants completed the same survey every two years from 1996 to 2008.

    About 20 percent of the survey participants reported doing regular unpaid work Researchers found that these volunteers also scored highest on their mental health scores. The two were linked so directly that the more a person volunteered, the happier they were.

    One could argue a chicken-and-egg theory: happier people are more likely to have the time, money, energy and resources to give back to others. But even when researchers adjusted for education, social class and total health, the link was there, suggesting that the mental increase came from volunteering and not the other way around.

    According to Dr. Stephen G. Post, author of The Hidden Gifts of Helping, when you help others, your brain releases feel-good chemicals, which can help cells repair themselves and grow. And this translates to better health.

    So volunteering can help improve both your physical and mental health—on one condition. You have to mean it. People who volunteered for "self-oriental" reasons, either because they were forced to do so for work or school or because they were trying to get away from problems in their lives, had a mortality(死亡率)risk that was similar to those who didn't volunteer at all. It was only when people were volunteering out of a true sense of sympathy that they saw any health benefits.

    So whether it's arranging books at the library or walking dogs at the animal shelter, find a cause that's important to you and give it a try. Volunteering is a good way to develop a sense of connection that not only helps your community, but may also be good for you.

    Luo Jingyu, 19, has four years of experience of running business. He is also a freshman in the arts department of Hubei University.

    Luo Jingyu is from an ordinary family. He said, "My parents told me if I wanted something I should make an effort to get it, so I earned pocket money by doing housework when I was little." The dream of running his own business grew in his heart. He said, "I want to be a successful person, like Alibaba's Ma Yun."

    When Luo was a junior student, he had the idea of selling lanterns when he saw many people flying Chinese lanterns in a square. Luo bought some lanterns from a store, but the sales were not as good as he had expected. Then he found another way to do business. He bought lanterns on the Internet at a very low price. Finally he easily made 5,000 yuan in two days.

    With a happy beginning, Luo planned to open a dress shop. "My parents didn't support me opening a dress shop, so I had to borrow 120,000 yuan for it." Although he did market research before starting, the business wasn't very good because his taste in fashion wasn't accepted by customers. The shop eventually closed down after half a year.

    After experiencing a big loss, he decided to do something he was familiar with—selling painting tools. As a fine arts student, he knew the market. He convinced his friends to invest one million yuan in his shop. With a good business mind and a lot of effort, the sales of the shop reached six million yuan in a year.

    Even though Luo is rich, he uses a cheap cell phone and does not wear luxury clothes. He has a simple lifestyle. "It isn't easy to make money, so money should be used on something worthwhile," he said.

    Medicine is the most noble of all the arts, but owing to the ignorance of those who practice it, and those who inconsiderately form a judgment of them, it is now far behind all the other arts. Their mistake appears to me to arise principally from the fact that there is no punishment for the practice of medicine except disgrace, and that does not hurt those who are familiar with it. Such persons are like the figures introduced in tragedies, for as they have the shape, and dress, and appearance of an actor, but are not actors, so also physicians are many in title but very few in reality.

    Whoever is to acquire a competent knowledge of medicine ought to process the following advantages: a natural character; instruction; a favorable position for the study; early tuition; love for labor; leisure. First of all, a natural talent is required, for Nature leads the way to what is most excellent; then instruction in the art takes place, which the student must try to adopt by reflection, becoming an early pupil in a place well adapted for instruction. He must also bring to the task a love of labor and perseverance to ensure the instruction takes root.

    Instruction in medicine is like the culture of the productions of the earth. For our natural character, is, as it were, the soil; the principals of our teacher are, as it were, the seed. Instruction in youth is like the planting of the seed in the ground at the proper season. Diligent study is like the cultivation of the fields; and it is time which passes on strength to all things and brings them to maturity

    Having brought all these essentials to the study of medicine, and having acquired a true knowledge of it, we shall thus, in travelling around, be respected physicians not only in name but in reality. Inexperience is a bad trait, and does harm to those who possess it, nurturing either timidity or audacity(胆大安为). For timidity reveals a want of powers, and audacity a lack of skill. Physicians who are eager for power or those who are undertrained are not a blessing to a community.

    Those things which are sacred or noble, are to be delivered only to sacred persons; and it is wrong to import them to the profane until they have been initiated in the mysteries of the science.

    ★Jane Sun, CEO of Ctrip
