广东省湛江市2020届高三上学期英语9月调研试卷

阅读理解

    Google previously announced successful tests of machine learning systems designed to assist doctors. In one case, Google reported AI had examined eye diseases with equal accuracy to doctors. Other tests showed that machine learning can be used to study large amounts of patient data to predict future medical events.

    Now the company has published two new studies showing a high level of success in identifying metastatic breast cancer. Metastatic means that cancer has spread from its main area to other parts of the body. Metastatic breast cancer is one of the deadliest, causing about 90 percent of all breast cancer deaths worldwide.

    In metastatic breast cancer patients, the cancer often travels to nearby lymph nodes(淋巴结). Usually doctors examine lymph node tissue under a microscope to see whether cncer is present Google notes that previous studies have shown that up to one-fourth of metastatic lymph node classifications end up being changed after a second examination. In addition, studies show that small metastatic material can be missed up to 67 percent of the time when examinations happen under extreme time restrictions.

    Google says it created a mathematical algorithm(算法).The algorithm, called Lymph Node Assistant, is trained to find characteristics of tissue affected by metastatic cancer. When the system examined tissue images (图像), it was able to differentiate between metastatic cancer and non-cancer 99 percent of the time. In addition, the Lymph Node

    Assistant is highly effective at finding the positions of the cancers. Some of these positions would be too small for doctors themselves to identify. The research also showed that the algorithm method can reduce the usual time needed to examine the disease by about 50 percent.

    But Google makes clear the Al-based system is not meant to replace the work of medical professionals. Instead, it is designed to reduce the number of false identifications and help doctors work faster and more effectively.

(1)、What is the main idea of Paragraph 1?
A、Google became a pioneer in training doctors. B、Machine learning is able to stop future medical events. C、Google developed artificial intelligence to help doctors. D、Artificial intelligence cured eye diseases with equal accuracy to doctors.
(2)、What can we infer about metastatic breast cancer?
A、One-fourth of the metastatic breast cancer patients die in the end. B、Metastatic breast cancer is very difficult to identify. C、It results in 90 percent of deaths of all cancers. D、It can be identified after a second examination.
(3)、What is the advantage of Google's new mathematical algorithm?
A、It can offer effective treatment. B、It can tell the exact positions of cancers. C、It costs 99 percent less time than before. D、It improves the accuracy of identifying cancers by 50%.
(4)、What influence will the mathematical algorithm bring?
A、False identification of cancers will be avoided. B、More effective prevention of cancers will be found. C、The number of medical professionals will be reduced. D、Doctors can have a faster understanding of patients' condition.

    Did you know that badminton is also a fast-paced competitive sport? Badminton has been a Summer Olympic sport since 1992. Para-badminton will be included in the 2020 Summer Olympic Games in Tokyo. Here's what you need to know if your child is interested in badminton.

    Badminton is played on a 44-foot-long rectangular (矩形的) court that is 17 feet wide for singles and 20 feet wide for doubles. It is divided in the middle by a net placed 5 feet off the ground, like volleyball, not at ground level like tennis.

In competition, each match is a set of three games played to 21 points. There is a one-minute break when a player or team reaches 11 points, and a two-minute break in between the first and second games and the second and third games.

Age kids can start: About 6 years old.

    Best for kids who: Have good skills, are patient and hardworking, and can handle the pressure of one-on-one or two-on-two competition.

Team or individual: Matches can be singles (one-on-one) or doubles (two-on-two).

    Fun fact: Badminton is the only sport that has mixed doubles event in the Olympic Games.

    Costs: Beginners are expected to pay $30 to $40 for an entry-level racquet (球拍). Badminton shoes are similar in price to other athletic shoes. Join a club or team for lessons. A one-hour group lesson for beginners should cost $20 to $25, with costs increasing as your child moves up the ranks. You will also pay entry fees for competitions.

    Time commitment required: Beginners will play for just an hour or two per week.

    Potential for injury: Players have a very low risk of injury. Players who wear glasses should use eye protection.

    Around three forty-five on a rainy Saturday morning, I was woken up by the sound of my pager(呼机) beeping. As a volunteer firefighter and emergency medical technician, I can never count on a full night of sleep. I pulled myself out of bed and went toward the desk to grab my radio. Our crew was being sent to a nearby home where a man was in cardiac arrest (心脏骤停). We found the man lying on the kitchen floor with his wife beside him. We rushed the patient to the hospital, but despite our efforts, we were unable to save his life.

    In my line of life, I rarely get any recognition from the patients we treat, or from their loved ones. But that night, a man's wife approached us, and through her tears, whispered, “Thank you.” Then she hugged each of us. She knew we answered her late-night call for help, even though the ending was not positive.

    There is something deeply rewarding about helping people in these circumstances. Sometimes, I'm able to make their worst day a bit better: like seeing the tears of an injured child turn into a smile when I gave him an interesting toy; or watching a terrified mother's screams turn into tears of joy when she realized her baby was going to be fine.

    Experiences like these allow me to see the impact my work has on others. At the same time, I also know the effect it has had on my own life. As a teenager, I felt awkward when my dad hugged me and said, “ I love you, my dear son.” I was equally uncomfortable and responded, “I love you.” But then I imagined him lying on the kitchen floor that rainy night and realized that my opportunity to say those three words could—at any moment—be taken away forever. Now, I extremely treasure the moment when my father says those three words to me. I've learned to appreciate every relationship I have, to tell people I care about them, and to never take anything in life for granted.

    The other day I was shopping at the local Chinese grocery store. There was a line at the fish counter, but only one staff person was there to take care of the customers. Some customers ordered quite an amount of fish for that staff person to work on. At last I was the second in line; all I wanted was a couple of crabs and should get out of there in no time.

    Noticing it was very busy at the fish counter, another staff person came over to help. I was ready to be served,  but the staff person went to the end of the line and began to help a couple of ladies with snails (蜗牛).The customer in front of me, being served, turned around and looked at me sympathetically, and the customer behind me called to the staff person, "You should start her, "pointing at me. He was, well, ignored.

    If someone asked me, "What is the most important rule to follow in America?"I would reply without hesitation, "Wait your turn at all times." Wherever you go here in this country, you will find people waiting in a line quietly to get anything: whether in the supermarkets, department stores, bus stops, or gas stations, it's just a matter of waiting your turn. In a larger sense, "wait your turn" is more than just a guideline﹣it is a very basic norm (准则)that reflects the fundamental value of the western cultures. But in some situations your turn does not always come based on when you get there and how long you have waited in line, just like my case at the store. Even though this did not often happen, it did make me feel upset.

    I was on my way home from work, cutting through the Bryant Park. On that day, the sun seemed to set faster than usual, and suddenly I found myself walking in the dark. I was less than half a mile from my apartment, but the path would lead me over a bridge, across train tracks, and through an unlit underpass.

    Then I heard him – a stranger running alongside me, partly obscured(遮掩) by the bushes. My mouth went dry; my legs felt like water. But I didn't pick up my pace – instead, I stopped, turned, and faced him. He came out of the bushes and said he'd been watching me "for a long time".

    As he walked beside me, I guided us towards the edge of the park. When we reached the bridge, a train rumbled(轰鸣着缓慢行进) past, and he seized the moment, attacking me with a knife around my throat. The self-defense skills I had learned years before kicked in, and I pushed my finger into his eye, hard. And then came the shock: That didn't frighten him away. My mind flashed back to a tip from an old guitar teacher: "Press the strings like you're squeezing a flea(跳蚤)." I put all my strength into that finger, and finally he let go.

    I was shaking with fear, but I looked him straight in the eye and began to back away. I turned to run the hell out of there, but then I remembered another self-defense lesson: Never run, because then you're a target. So I walked away alone – through the dark tunnel as I dialed 911 with trembling fingers. If you ever find yourself in this situation, use these self-defense skills that you already know. They can really make all the difference to you.

Imagine a school where students are taught by the best teachers in every subject, regardless of location. Imagine a school where students could go on safe field trips to the Amazon rainforest or Everest base camp. Well, such schools are already being built: in virtual(虚拟的)reality. 

Last year, Optima Academy Online, an all-virtual school, delivered courses that aim to improve the hearts and train the minds of young people. These courses are of different levels, attracting 170 full-time students from all over Florida. In the progress of home-schooling, students use headsets for about three hours a day for formal lessons and then do course work independently with digital check-ins. 

Future versions(版本)of VR will doubtless be widely used in education, but the only questions are: for what purpose and at what speed? There are enough reasons to doubt whether VR schools represent the future of education. Sticking a child in their bedroom with a heavy VR headset fastened to their face and no physical social interaction with other kids will fill many of them and their parents with horror. 

A recent report concluded that digital education could significantly improve the quality and equality of schooling systems. But if managed poorly, it could have the opposite effect, turning a digital divide into an educational one. There is growing evidence to suggest that is happening. In Mexico, only 24 percent of 15-year-old students in poor schools have access(使用)to a home computer for schoolwork compared with 87 percent in rich ones. 

Used properly, technology can be great for enabling self-motivated students to access learning resources and connect with fellow students and teachers all over the world, says Beeban Kidron, a member of the UK's Digital Futures Commission. The trouble is that Edtech is too often seen as a shiny new toy that will solve all problems and save money rather than being viewed as a different way to learn, she adds.
