湖北省武汉市第二中2024届高三下学期5月模拟考英语试卷

 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。

Some people today might be early risers because of DNA they take after Neanderthals tens of thousands of years ago, suggests new research.

When early humans migrated from Africa to Eurasia roughly 70,000 years ago, some of them mated with Neanderthals, who had already adapted to the colder, darker climates of the north. The ripple (涟漪) effects of that intermating still exist today: Modern humans of non- African ancestry (血统) have between 1 and 4 percent Neanderthal DNA. Some of that DNA relates to sleep more specifically, the internal body clock known as the circadian rhythm.

For the new study, researchers compared DNA from today's humans and DNA from Neanderthal fossils (化石). In both groups, they found some of the same genetic variants involved with the circadian rhythm. And they found that modern humans who carry these variants also reported being early risers.

For Neanderthals, being "morning people" might not have been the real benefit of carrying these genes. Instead, scientists suggest, Neanderthals' DNA gave them faster, more flexible internal body clocks, which allowed them to adjust more easily to annual changes in daylight. This connection makes sense in the context of human history. When early humans moved north out of Africa, they would have experienced variable daylight hours--shorter days in the winter and longer days in the summer-for the first time. The Neanderthals' circadian rhythm genes likely helped early humans' offspring (后代) adapt to this new environment.

Notably, the findings do not prove that Neanderthal genes are responsible for the sleep habits of all early risers. Lots of different factors beyond genetics can contribute, including social and environmental influences. The study also only included DNA from a database called the U.K. Biobank-so the findings may not necessarily apply to all modern humans. Next, the research team hopes to study other genetic databases to see if the same link holds true for people of other ancestries. If the findings do apply more broadly, they may one day be useful for improving sleep in the modern world, where circadian rhythms are disturbed by night shifts and glowing smartphones.

(1)、What does the new research focus on?
A、DNA's dramatic changes. B、Genes' influence on early risers. C、Neanderthals' sleeping patterns. D、Ancestors' environmental adaptability.
(2)、What is paragraph 2 intended to show concerning the new research?
A、Historical context. B、Additional proof. C、Sample analysis. D、Studying process.
(3)、What is the real benefit of carrying Neanderthal's DNA for modern humans?
A、Getting up earlier. B、Having healthier daily routines. C、Being more flexible in their work. D、Possessing a better circadian rhythm.
(4)、What can be inferred about the findings from the last paragraph?
A、They get proof from other studies. B、They are confirmed by early risers. C、They suggest potential applications. D、They reveal factors in sleeping disorders.

    Having a clean and organized workspace takes time and effort—especially if we want to keep it that way. {#blank#}1{#/blank#} According to recent statistics, the average office employee spends one and a half hours a day looking for things. That's an hour and a half that is wasted every day because of disorganization. Keeping things organized can give you more time each day. Having a clean workspace can have a number of additional surprising benefits. Let's look at some of those now.

{#blank#}2{#/blank#}

    Untidiness can be a distraction that interferes with your thought process and prevents you from being as effective as you can be. When your workspace is clean and organized, you can spend more time focused on your tasks, without the unorganized chaos to attend to.

Attain More Success

    It's hard to be productive when you're disorganized. Organization can make it easier to concentrate, and allows you to get things done faster. Whether you're an employee or self­employed, organization is a crucial component for success. If clients see that you're well­ organized, they'll be more willing to trust you.{#blank#}3{#/blank#}

Make a Better Impression

    In addition to making it easier to focus and work, having a clean workspace also helps to convey a professional image. Your workspace says more about you than you may think. When someone walks past your space, they instantly form an opinion about you based on what your space looks like.{#blank#}4{#/blank#} However, to the outsider, you may look overwhelmed and incapable of taking on extra projects.

Have a Happier Work Experience

    If you're surrounded by a clean environment you'll have space to think, will be able to get more done and will feel better working in that space.

Fortunately, keeping your space clean and organized is easier than you might think.{#blank#}5{#/blank#} You'll be amazed at the difference a clean workspace can make to your mindset and how much more you'll be able to accomplish during the day.

A. Improve Focus

B. Regain Tidiness

C. But the results are more than worth it

D. Maybe you feel productive with papers scattered around

E. It shows that you know what you're doing and that you are capable

F. Clearly being disorganized can have a negative effect on your performance

G. Try to get rid of or throw away everything that you don't need to maximize your productivity

    Cold weather during winter months may keep many people from leaving home and running in the open air.

    However, a new study shows that the drop in temperature is a good reason to run. In fact, researchers say, running in cold weather helps improve one's performance.

    Many people say running in the winter can be difficult. Two reasons are the low temperatures and bitter winds. Yet many runners might find it easier than running in hot weather.

    That could be because lower temperatures reduce stress on the body. When you run in cold weather, your heart rate and the body's dehydration (脱水) levels are lower than in warmer conditions. The body needs less water on a cold day than in warm weather.

    This information comes from sports scientists at St. Mary's University in London. John Brewer is a professor of applied sport science at St. Mary's.

    For this study, he and other researchers put a group of people into a room they called an "environmental chamber." The researchers then recreated summer and winter weather conditions in the room. The test subjects were asked to run 10,000 meters under both conditions. Brewer says he and his team recorded biological measurements of the runners.

    "We've got a group of subjects into the environmental chamber, we've changed the conditions to replicate the summer or winter and we've got them to run a 10km under both of those conditions and taken various measurements on each runner while they've been completing their 10km."

    Brewer says every movement runners make produces heat. He explains that one way in which we lose heat is by sweating. The body loses heat through droplets of sweat. He says the body also loses heat by transporting the blood to the surface of the skin.

    Frequently, we speak about people being “color-blind” but very few of us are. Even those who describe themselves as color-blind are normally just color lack. A strongly, color-blind person will still be able to tell 20 different colors, compared to the 100 or so that normal-sighted people see.

    Pingelap, a tiny island in the Pacific, is a beautiful spot but one that has a genetic trouble. It is known as Color-blind Island because so many people who live on this remote island can only see black and white.

    Not being able to see colors is bad enough. But one islander, Herrol, who's a fisherman, also struggles in full sunlight because all he sees is a painful burnt-out image. “I find it difficult to go outside in the sun,” he says, “because when it's sunny I cannot see to do my work.”

    But if being truly color-blind is rare, why is it that around 10% of the population of Pingelap live in a totally black and white world?

    Well, we know that in 1780 the population of Pingelap was all but wiped out by a tsunami (海啸). As few as 20 people survived, one of whom was the king. It's believed he had a genetic fault that causes colour-blindness and he passed this fault on to his many generations.

    There is one advantage. Herrol can see well, really well, in the dark. So when it gets dark, Herrol and his friends get in their boats and hunt flying fish. They hang up flaming torches and the fish are attracted to the flames. “This type of fishing is fun,” Herrol says, “especially if we catch plenty. So even though it's hard work we enjoy it.”

    Your kids learn a lot from their friends—things you can't teach them, no matter how much you want to.

    Probably the most important thing kids learn is how to have peer relationships. As a parent, you can't do this, because you and your child aren't equals.

    For example, when you're sitting on your family room floor and your very young child asks you to pass him the blocks, you probably hand them right over. If your child is sitting with a peer and asks the same thing, though, he might not get what he wants.

    To succeed, your child will need to learn strategies for getting what he wants. For example, he might simply yank (猛拉) the toy out of his friend's hand. If he does that, he may learn that it's not the best way of getting what he wants because it leads to fighting and time­outs. The successful child will learn that he needs to negotiate a trade, to wait patiently, or to find something else equally fun to play with.

    Friends also provide emotional support, something that is part of the foundation of healthy adulthood. You can't be with your child on the elementary school playground or at the high school dance. Your child's friends will be the ones to stick up for her, to include her in games, and later, to tell her she looks great even if her lousy prom (糟糕的舞会) date wanders off instead of dancing with her.

    Friends also help your children learn. Friends solve problems together, imitate each other, and pass on knowledge.

    Some experts believe that the single biggest predictor of your child's success later in life is her ability to make friends. In fact, they claim it's even more important than IQ and grades.

    This doesn't mean that the kids who are most popular in school do the best later on in life. What matters is not the number of friends a child has but rather the quality of the relationships.

    This is good news for those of us who hate to think that popularity really is the Holy Grail of childhood and adolescence. While it's true that popularity has many advantages, and that many popular kids really are nice people—and not just the best dressed or best looking—it's better to have a few good friends than to have the admiration of the masses.
