• 1、In a clinical trial with 80 adults, a team of researchers found that sleep extension reduced energy intake and resulted in a negative energy balance in real-life settings among adults with overweight who habitually reduced their sleep duration (持续时间). The findings appear in the journal JAMA Internal Medicine.

    Obesity is a major public health concern. Much evidence suggests that sleeping less than 7 hours per night on a regular basis is associated with adverse health results. Particularly, insufficient sleep duration has been increasingly recognized as an important factor for obesity. However, it remains unknown whether extending sleep duration can be an effective strategy for preventing obesity.

    The clinical trial involved 80 adults aged 21 to 40 years with a body mass index (BMI) between 25.0 and 29.9, and habitual sleep duration of less than 6.5 hours per night. The study was conducted from November 1, 2014 to October 30, 2020. The participants were able to increase their sleep duration by an average of 1.2 hours per night after a personalized sleep counseling (咨询) session.

    Overall, participants who increased their sleep duration were able to reduce their calorie intake by an average of 270 kcal per day — which would translate to roughly 12 kg of weight loss over three years if the effects were maintained over a long term.

    Ultimately, the researchers hope to examine the underlying (潜在的) mechanisms that may explain these results, and believe their work should encourage new, larger studies on weight control to determine if extending sleep can support weight-loss programs and help prevent or reverse obesity.

    "In our earlier work, we understood that sleep is important for appetite regulation," Dr. Tasali said. "Now we've shown that in real life, without making any other lifestyle changes, you can extend your sleep and eat fewer calories. This could really help people trying to lose weight."

    (1)、What's the new finding of the research?
    A、Sleep extension can lead to weight problems. B、Extending sleep duration helps reduce caloric intake. C、Controlling energy intake is the key to losing weight. D、Overweight adults often decrease their sleep duration.
    (2)、What's the probable meaning of the underlined word "adverse" in paragraph 2?
    A、Harmful. B、Unique. C、Lasting. D、Apparent.
    (3)、According to the text, the subject of the study ________.
    A、usually slept 6.5 hours per night B、were 80 adults of the similar age group C、got advice on sleep tailored to themselves D、were particularly chosen from a certain place
    (4)、What do researchers think of the study?
    A、Its results are hard to explain clearly. B、It lays a foundation for further studies. C、It's unreliable with many factors ignored. D、It has solved all the puzzles of researchers.
  • 2、To Karanth, everyone in every part of the world is born with a fundamental connection to nature. Growing up in Karnataka, she began accompanying her father into the wild at just two years old. But in her hometown, kids grew up with a negative perspective (看法) on wildlife. Elephants destroyed crops and sometimes people were badly injured or killed. Karanth discovered kids wouldn't appreciate the fact that it's the best place to witness extraordinary animals.

    In 2017, a conversation with her friend Gabby shifted her mindset towards education. Within half a year, Karanth and Gabby had the first version of "Wild Shaale" on their hands. A program designed for students who come into frequent contact with wildlife, Wild Shaale aims to develop a genuine understanding of wildlife and wild spaces and move beyond wildlife tolerance to concepts of conservation (保护) and environmental issues. The conservation education program fills a gap in environmental learning.

    While it is fortunate that a basic environmental education is supported by local government, Karanth believes the challenge lies in the quality of the curriculum and whether it's delivered effectively and consistently. "You have to visualize (想象) what these schools look like. They may not have electricity—forget having computers, internet, iPads, or anything. "

    Encouraging the students to find commonalities between themselves and the animals is the first step to changing perceptions (看法) and hopefully, behaviors. "It comes down to the same things: we need food; we need water; we need space. Then they start to understand why situations of conflict arise," Karanth says. "But then how do you convince them not to get angry, not to act in a way that leads to harm? That's something we're trying to work on. It's not easy."

    (1)、What problem might Karanth's hometown have faced?
    A、Human-wildlife conflict. B、Loss of wildlife habitats. C、Overpopulation of elephants. D、Disregard for wildlife balance.
    (2)、Why did Karanth launch the program Wild Shaale?
    A、To help students identify animals. B、To fill a gap in local education. C、To change how students perceive wildlife. D、To publicize wildlife diversity.
    (3)、What does paragraph 3 mainly talk about?
    A、The support for the plan. B、The barrier to the program. C、The curriculum arrangement. D、The schools' conditions.
    (4)、What is Karanth trying to achieve in the program?
    A、A change in humans' attitudes and behavior. B、A breakthrough in environmental studies. C、Appropriate ways to end local conflicts. D、Approaches to changing animals' behavior.
