河南省周口市九师联盟四月联考2023-2024学年高三下学期4月期中英语试题(音频暂未更新)

阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。

The Ebola virus is an infectious disease that for years had almost no treatments, and it kill s about half the people it infects. Now a new study published in The Lancet Infectious Diseases shows that a promising vaccine (疫苗), named rVSV△G-ZEBOV-GP, doesn't just help to reduce infections, it also can cut those death numbers in half.

The vaccine is a single-dose (单剂) muscular one that causes cells to produce one of the virus's proteins. "Later, if the person is exposed to Ebola,"explains Rebecca Coulborn, a scientist with Epicentre, the medical research arm of Doctors Without Borders, "their immune system will recognize the viral protein. This recognition allows the immune system to be prepared to attack the virus and protect the person from Ebola virus disease."

Researchers showed rVSV△G-ZEBOV-GP was effective at reducing the risk of infection, but no one knew how capable it was of preventing death in someone who was vaccinated after becoming infected during an epidemic (流行病). To figure it out, Coulborn and her colleagues focused their efforts on the second-largest Ebola outbreak ever recorded, which occurred in the Democratic Republic of Congo between 2018 and 2020.

"Every single Ebola health facility across the entire Ebola epidemic had a standardized list of all admissions," says Coulborn. This list included 2,279 confirmed Ebola patients, and it recorded whether or not each person had been vaccinated before they got sick—and if so, when they'd received the vaccine.

Coulborn found the death rate was 56% among the unvaccinated. But for those who'd received the vaccine, that rate was cut in half. This was true no matter when someone got vaccinated before the appearance of symptoms. Additionally, those who'd been vaccinated had less virus circulating in their bodies than those who hadn't. So the vaccine played an important role.

Rebecca Coulborn says she feels buoyed by the results—since they offer clear evidence that people who're at risk of contracting Ebola should be vaccinated early. It's an opportunity to cut chains of transmission (传播) and prevent an outbreak before it gains speed.

(1)、What is Coulborn trying to talk about concerning the vaccine in paragraph 2?
A、Who it attacks. B、Why it is developed. C、How it works. D、Where it comes from.
(2)、Coulborn's team chose the second largest Ebola outbreak in Congo because ____.
A、it listed health facilities B、it was easy to analyze C、it caused the fewest deaths D、it had a detailed record
(3)、What did Coulborn probably suggest people infected do?
A、Avoid connecting with each other. B、Get vaccinated as early as possible. C、Stay at home to reduce the spread. D、Learn to recognize the symptoms.
(4)、What does the underlined word "buoyed" in the last paragraph probably mean?
A、Encouraged. B、Relaxed. C、Astonished. D、Honored.

    What Theresa Loe is doing proves that a large farm isn't a prerequisite for a modern grow-your-own lifestyle. On a mere 1/10 of an acre in Los Angeles, Loe and her family grow, can (装罐) and preserve much of the food they consume.

    Loe is a master food preserver, gardener and canning expert. She also operates a website, where she shares her tips and recipes, with the goal of demonstrating that everyone has the ability to control what's on their plate.

    Loe initially went to school to become an engineer, but she quickly learned that her enthusiasm was mainly about growing and preparing her own food. “ got into cooking my own food and started growing my own herbs(香草)and foods for that fresh flavor,” she said. Engineer by day, Loe learned cooking at night school. She ultimately purchased a small piece of land with her husband and began growing their own foods.

    “I teach people how to live farm-fresh without a farm,” Loe said. Through her website Loe emphasizes that ''anybody can do this anywhere.” Got an apartment with a balcony (阳台)? Plant some herbs. A window? Perfect spot for growing. Start with herbs, she recommends, because “they're very forgiving.” Just a little of the herbs “can take your regular cooking to a whole new level,” she added. “I think it's a great place to start.” Then? Try growing something from a seed, she said, like a tomato or some tea.

    Canning is a natural extension of the planting she does. With every planted food, Loe noted, there's a moment when it's bursting with its absolute peak flavor. “I try and keep it in a time capsule in a canning jar,” Loe said. “Canning for me is about knowing what's in your food, knowing where it comes from.”

    In addition to being more in touch with the food she's eating, another joy comes from passing this knowledge and this desire for good food to her children: “Influencing them and telling them your opinion on not only being careful what we eat but understanding the bigger picture,” she said, “that if we don't take care of the earth, no one will.”

    There are so many expressions in American English that sound good but are not.

    "Face the music" is a good example. When someone says they have to face the music, it does not mean they are going to a musical show or concert. To face the music means to accept the bad results of an action.

    Imagine a friend asks you to take care of her beautiful red sports car. She gives you the keys and says, "Thanks so much for watching my car while I'm away. But please do not drive it. It is a very fast car and you are not on the insurance (保险)."

    But you do not listen. You want to show it to some friends and pretend(假装) the car is yours. So, you drive it around town one night. As bad luck would have it, you lose control of the car and drive it into a stop sign. The damage is serious. When your friend returns you must tell her what you have done and "face the music".

    The "music" here is the result of your actions. It could be losing her friendship or paying for repairs to her sports car or both. Whatever the music is, you must face it.

    There are other American expressions that mean the same as "face the music".

    To "take your medicine" means to accept the results from something bad you have done. And if someone says, "You made your bed. Now lie in it." He means you created a bad situation and now you will experience the results, or as we say in American spoken English, you must deal with it!

    "Pay the piper" also means the same as "face the music". But, that expression has its own very interesting beginning. We will talk about that in the next Words and Their Stories.

    "Have a nice day!" may be a pleasant gesture or a meaningless expression. When my friend Maxie says "Have a nice day" with a smile, I know she sincerely cares about what happens to me. I feel loved and secure since another person cares about me and wishes me well.

    "Have a nice day. Next!" This version of expression is spoken by a salesgirl at the supermarket who is rushing me and my groceries out the door. The words come out in the same tone(腔调)with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else's is the management's attempt to increase the business.

    The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting is at an end. Sometimes the expression serves us when we don't know what to say." Oh, you just had a tooth out? I'm terribly sorry, but have a nice day."

    The expression can be pleasant. If a stranger says "Have a nice day" to you, you may find it heart-warming because someone you don't know has tried to be nice to you.

    Although the use of the expression is an insincere, meaningless social custom at times, there is nothing wrong with the sentence except that it is a little uninteresting. The salesgirl, the waitress, the teacher, and all the countless others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it's nice to know they care enough to pretend they care when they really don't care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.

 阅读下列短文,从每题所给的A、B、C 和 D 四个选项中,选出最佳答案。

Concrete has served as the foundation stone of the construction industry for hundreds of years. However, the process of producing concrete is one of the most environmentally unfriendly processes in the world. In the process, not only is carbon dioxide(二氧化碳)released into the air by the energy used to heat the limestone, but the limestone itself also gives out a huge amount of the element. 

Luckily, a number of start-ups throughout the world are using creative thinking to make the construction industry a whole lot more friendly for the planet. 

A Canadian company called CarbonCure, has found a way to inject(注入)concrete with carbon dioxide itself. Not only does this trap the carbon dioxide into the concrete, keeping it from running away into the atmosphere, but it also creates a super strong material called calcium carbonate, which reduces the total amount of concrete that needs to be used. 

California-based Brimstone, is creating carbon-negative concrete by doing away with limestone entirely and instead using silicate rock, a material that does not release carbon dioxide when heated. Instead, the process produces magnesium(镁), which absorbs carbon dioxide, as the basis for their concrete. 

Additionally, researchers at Australia's RMIT University have recently released a study showing that adding coffee grounds instead of sand to concrete could make it much stronger, reducing both the amount of sand used, as well as the amount of concrete that would need to be used in the final product. 

The biggest barrier at this point is convincing members of the industry that the new types of concrete are safe to be used, according to Stacy Smedley, director at a nonprofit focused on decarbonizing construction. 

Hopefully these new solutions to the environmental problems of concrete will soon be widely adopted. Given the significant part the construction industry has in releasing carbon dioxide into the atmosphere, great improvements can be made when more environmentally-friendly materials are used.
