And new research shows it may also make people eat morebut only if theyre male*.The finding is from Carmit Levy, a researcher who had been studying how sunlight affects the risk of skin diseases. She exposed* a group of
2、 mice to sunlight for a few weeks, and unexpectedly found that sunlight made male mice get heavier, but not females*. The males also worked harder to get food that was difficult to reach.That interested her, so Levy and her team did further studies. They invited volunteers for two tests. Both showed
3、 that men and women were affected differently by sunlight. Then, they got data from almost 3,000 people. These data told that 1,330 men required about 2,188 daily calories* in summer months and only needed 1,875 calories in other months. The 1.661 women needed about 1,500 calories each day all year
4、long.Encouraged by this, the team ran more mouse experiments to test what might explain such findings. And the reason may be connected with these three things. The first is p53. Its levels will rise when the body is under stress. For animals that are usually active at night, such as mice, sunlight c
5、an be a cause of stress. The second key player is ghrelin. When the stomach is empty, it travels to the brain to send the message that the body needs food. The last is estrogen*. Its levels are much higher in females than males.Heres what may happen in male mice exposed to sunlight. First, the stres
6、s of sunlight makes p53 in the skin start to work. This p53 then tells the skin to create ghrelin. Therefore, the mice eat more. But in female mice, the estrogen seems to interfere the production of ghrelin. As a result,the female mice may not feel so hungry. Thats to say, estrogen provides females
7、with a greater protection against various forms of stress.The idea that sunlight may affect the need for food is interesting. But being sure the key players and how they work with each other will require much more research.1After exposing the male mice to sunlight for weeks. Levy found they _.Againe

It is created to copy a natural forest, bringing all its benefits, but for a small space in cit
11、ies. The first tiny forest was planted by a Japanese plant expert. Dr. Akira Miyawaki in the 1970s. It was so great that it grew quickly in countries such as Denmark, Britain, Germany, Ireland and Spain.As the name suggests, the place doesnt have to be big. An area the size of about 200 is perfect.
12、600 trees, with as many as 40 different kinds, can be planted in the place. With 2 to 7 trees every square metre, the trees are planted much more closely than the ones in normal forests. But theres still room for the trees to grow naturally without the use of fertilizers.To plant a tiny forest, one
13、starts with testing the soil and choosing right kinds of trees. In cities, the soil is often in poor condition. It is important to create loose and rich soil. When the soil is prepared, the community will invite school children on a planting day. The forests need 2 to 3 years of care from children.
14、Then the trees can become self-growing. Its believed if children plant their own forest and spend a lot of time caring for it, they will grow up to be healthy adults with a sense of responsibility for the society.Trees and forests arent special pieces of nature that should only exist in the countrys
15、ide. They need to be a part of life in cities too.5The idea of a tiny forest came from a scientist in _.ABritainBJapanCGermanyDSpain6Whats special about a tiny forest?AThere are usually about 7 kinds of trees.BIt usually covers an area of about 600.CIt grows quickly with the help of fertilizers.DTre

When it comes to waste management, Sweden is
18、ahead of its time. How has Sweden done it?In Sweden, everyone works hard to make the environment free of waste. People are taught to recycle from a very young age. They are asked to return cans and bottles to supermarkets. The government places recycling stations no more than 300 meters from homes,
19、schools, and offices. These all help waste management in Sweden much easier and more practical. The country also rewards those who recycle. In 1984, Sweden started the panta system. It encourages people to recycle bottles in exchange for money. The process is very simple. People put their items into
20、 a machine. Each piece has a small barcode that tells the machine how much it is worth. People can collect a voucher for that amount by pressing a green button, or they can donate the money to charity by pressing a yellow button. In 2021, the Swedish recycled 1.8 billion bottles and cans by using pa
21、nta system. Sweden recycles nearly 50% of what it throws away. But what about the other half? _ Altogether Sweden has 34 waste-to-energy plants that provide 1, 445, 000 homes with heat and 780, 000 homes with electricity. Changing waste into energy has reduced Swedens CO2 emissions by 2.2 million to
22、ns a year. In 2016, Sweden had started running out of trash, so it began importing waste from other countries. It not only keeps the plants working, but also lets Sweden make much money. That is what makes Sweden different from the other countries. Swedens waste management has made a great success.
23、But still, the country is wondering how it can do more. They hope to see a day when landfills are a thing of the past.9The word “These” in Para. 2 refers to the _ that help to recycle the waste.AplansBmeaningsCactionsDreasons10In the panta system, people can _.Afind recycling stations easilyBsell bo
