阅读短文,从各题所给的A、B、C、D四个选项中选择最佳选项。

    Studies have shown that a good night's rest helps us stay healthy. Researchers say sleep is probably the best tool we have for memory and learning.

    "Getting a good night's sleep is important for the learning and memory process. It's important because it stores (储存) the training and learning exercises into our memory forever while we're sleeping 7-8 hours in bed. And then the next morning when we wake up, our mind is better prepared to act on that information," Twery, an expert on the science of sleep said.

    But what about getting rest during the middle of the day? Past studies have shown that napping can help babies and young children learn better. In fact, napping can help older adults with their brain performance and may also help this group of people fight off age-related (年龄相关) memory loss.

    The researchers studied 3, 000 people and found that those who took an hour-long nap did much better on mental (智力的) tests. The hour-long nappers also did better on the tests than those who napped for shorter and longer periods. But researchers note that these findings are for those over 65, and for young, healthy adults, an hour-long nap may be too long.

    "At present, we're suggesting that we try to nap for about 30 minutes or less. Thirty minutes is enough to remove (消除) the pressure and will help us feel more awake. If we nap longer, we will get trapped into (陷入) the deep sleep, which can be hard to get out of, "Twery said. This feeling is called sleep inertia (迟钝)—the period when you awake from a very deep sleep. For a time, you are unable to think clearly.

(1)、From Paragraph 1, a good night's sleep ________.
A、is usually 7-8 hours B、makes people become smarter C、makes people wake up early in the morning D、helps with people's learning and memory
(2)、The underlined word "napping" in Paragraph 3 means "________".
A、a short sleep during the day B、a good sleep during the day C、a deep sleep at night D、a long sleep at night
(3)、What does the result of the study show?
A、The time of napping should be controlled B、The hour-long nappers are much smarter. C、Young adults need more napping time. D、The deeper you sleep, the longer you'll sleep.
(4)、What is the passage mainly about?
A、How does napping influence people's health? B、Napping may improve learning and memory. C、The importance of having a good night's sleep. D、How long should people take a nap during the day?
(5)、In which part of a newspaper can we find the passage?
A、NATURE B、SPORTS C、HEALTH D、CULTURE

If you have seen the movie Journey to the Center of the Earth(《地心历险记》), you may wonder about the underground forest world. But such worlds can really be found in real life, too!

In early May 2022, a team of Chinese scientists and explorers found a large sinkhole (天坑) in Leye county, Guangxi. It is 306 meters long, 150 meters wide and 192 meters deep. "It didn't take us long to reach ground to walk on at first. We soon realized that we were nowhere close to the bottom of the 192-meter-deep sinkhole." Li Xinchen said. They also found trees up to 40 meters high and plants that came up to their shoulders, which makes it hard for scientists to walk in the forest. For them, the underground forest is almost like a spider web (网).

According to Xinhua News Agency, the local people in Leye county are no strangers to sinkholes. The county is called "the museum of sinkholes" where people have found 30 sinkholes so far. These sinkholes are formed because of the special karst landscape (喀斯特地貌). Karst is an area of land made up of limestone (石灰岩), which is a soft rock that can be easily mixed with water. When rain water flows through little cracks (裂缝) in the bedrock, the cracks are slowly enlarged. Over time, as the underground structure of the land becomes too weak to support the surface (表面) of the earth and then it falls slowly, opening up huge sinkholes. What's amazing is the great size of China's sinkholes.

"In China, they have this unbelievable karst with large sinkholes. In other parts of the world sinkholes might be far more undersized, only a meter or two in diameter (直径)," US researcher George Veni told Live Science. Sinkholes don't just look cool, they are gifts of life. Many of them are home to ancient plants, animal and microbe (微生物) lives. They also provide water for 700 million people worldwide.

 阅读下面语篇,从每题所给的A、B、C三个选项中,选出各题的最佳选项。

Jesselyn Silva's everyday life isn't like most young girls' life. She runs, hits a punching bag and spars with her coach after school. As a world-class boxer, Jesselyn is exactly different from other girls.

Jesselyn trains hard every day in Hackensack, New Jersey, a town about 15 miles outside New York City. She started boxing when she was seven years old. Jesselyn said, "One day I saw my dad hitting a punching bag and I wanted to do what he was doing." Then she had a dream to be one of the best female boxers.

One of the things she enjoys most about boxing is the tight-knit circle, in which a group of people are closely connected with each other. She said, "Everyone gets along and I like how everyone treats each other." She and her father have made many friends through the sport.

Jesselyn has her autobiography(自传), My Corner of the Ring, which is an inspirational story of her journey in boxing. She wrote it to encourage other girls to let go of their fears of competing. Jesselyn thinks boxing is about facing fears and overcoming them. "It may seem scary at first, but once you start and stand on the ring(拳击台), it's really fun. It takes a lot of hard work to win," she said, "and if you have a desire to be great, you must try your best."

Jesselyn believes that female boxers are getting more and more attention. Her dream is to become a pro, go to the Paris 2024 Olympic Games and become an Olympic champion. With her hard work, Jesselyn seems to be on the way to making her dreams come true.
