【推荐3】Most people are told to drink 8 glasses of water daily, However, how much water you should drink each day can depend on how big you are.     1     For example, if you weigh 150 pounds, you should drink 75 ounces of water daily. Besides, other factors can also affect how much water you should drink daily.

    2     If you are active in sports or the weather is warm where you live, you should drink more water. This is because your body will lose fluids as you sweat. Drinking sufficient amounts of water will top up the fluid level in your body.

People who are suffering from some illnesses and those with special needs typically should drink more water daily. Increasing water intake not only tops up the body's fluids, but it also helps the body flush（冲走）out unwanted substances.     3     Drinking more water daily will help remove them.

    4     It is often said that a person needs to drink less water daily if he or she consumes watery foods, such as soups or melons. Others believe that drinking other beverages（饮料）will reduce the amount of water that a person needs to drink daily.

It is possible to overdose（过量）on water.     5     Drinking too much water can cause many types of symptoms like headaches and confusion. Therefore, we should drink the proper amount of water based on our physical condition.

A paper published in the journal Trends in Plant Science details how plants are rapidly adapting to the effects of climate change, and how they are passing down these adaptations to their offspring(后代).

Plants are facing more environmental stresses than ever. For example, climate change is making winters shorter in many locations, and plants are responding. “Many plants require a minimum period of cold in order to set up their environmental clock to define their flowering time,” says Martinelli, a plant geneticist at the University of Florence. “As cold seasons shorten, plants have adapted to require shorter periods of cold to delay flowering. These mechanisms allow plants to avoid flowering in periods when they have fewer opportunities to reproduce.”

Because plants don’t have neural(神经的) networks, their memory is based entirely on cellular(细胞的),molecular(分子的),and biochemical networks. These networks make up what the researchers call somatic memory(体细胞记忆). “It allows plants to recognize the occurrence of a previous environmental condition and to react accordingly,” says Martinelli.

These somatic memories can then be passed to the plants’ offspring via epigenetics(表现遗传). “Several examples demonstrate the existence of molecular mechanisms modulating plant memory to environmental stresses and affecting the adaptation of offspring to these stresses,” says Martinelli.

Going forward, Martinelli hopes to understand even more about the genes that are being passed down. “We are particularly interested in decoding the epigenetic alphabet without changes in DNA sequence(序列),”he says. “This is especially important when we consider the rapid climate change, we observe today that every living organism, including plants, needs to quickly adapt to survive.”

However, one can never expect that this third-generation inheritor of the national-level intangible heritage of dough figurine making is a young man born after 1995.

Lang developed an preference for the art at a young age, starting to learn the craft (手艺) from his father when he was about four to five years old. Despite repeatedly practicing the same skills, the boy never felt bored. Instead, he gained quite a great deal of pleasure from the craft. Under the influence of his father, Lang developed a sense of responsibility to carry forward the art when he was young.

Lang had previously considered dough figurines to be an old-fashioned craft, having also felt that the raw materials used for the craft formed a limit on his creativity, stirring up doubts as to why he had chosen making dough figurines as a career from the beginning. However, when Lang visited an art exhibition as a university student, he was impressed by how one artisan there had made bread into various shapes, and then dried them to generate cracks on their outer surfaces to present a unique aesthetic form.

“Then, I came to realize that instead of complaining about the raw materials, I should pay more attention to improving my skills so that I could turn the ‘disadvantages’ of the dough into something that I could make full use of to make my works more expressive,” Lang said.

The young man has also turned to new media to promote the art of dough modeling. For Lang, making dough figurines is a process of self-expression, and it gives him great pleasure to just be himself. “This is what I’m good at and attracted to, and I’m delighted to see a trend toward the revitalization (复兴) of traditional Chinese culture nowadays,” said Lang.

【推荐3】The Tibet autonomous region plans to have 4,000 kilometers of rail lines by 2025 and eventually connect all its 55 counties and districts by rail, according to the region’s Development and Reform Commission. The region will expand and improve the quality of its railway network so that rail coverage in the region sees significant growth, and the contribution of railways to local economies and social development is further strengthened.

The rail network plan for the 14th Five-Year Plan (2021-25) period and beyond was released recently by the commission. By 2025, the construction of several railway projects, including the Ya’an-Nyingchi (林芝) section of the Sichuan-Tibet Railway, the Shigatse (日喀则)-Pakhuktso section of the Xinjiang-Tibet Railway and the Borni-Ra’uksection of the Yunnan-Tibet Railway, will all see major progress, according to the plan. Other key projects include the electrification (电气化) of the existing Qinghai-Tibet Railway and upgrading the double-track railways of the Pakhuktso-Hetian line of the Xinjiang-Tibet Railway.

The region’s rail network will reach 4,000 km by 2025 and 5,000 km by 2035. A will also be formed by 2035. comprehensive railway network linking Lhasa, the regional capital, to neighboring provinces

Hampered by geological and technical challenges, construction of railway lines in Tibet has always lagged behind the rest of the country, with the region currently having only three rail lines in operation and the combined length of the tracks is 1,359 km. With a length of 435 km and a top speed of 160 km, the Lhasa-Nyingchi Railway is the first electric railway in Tibet, which is a part of the Sichuan-Tibet Railway.

Yang Hao, a professor at Beijing Jiaotong University, said more railway projects are planned to link Tibet with neighboring provinces. “Once these new rail lines become operational, more cities in the region will be accessed by rail services to cities in northwestern and southwestern China, and more railways will be facilitated along the border ports,” he said, “It is of great value in contributing to the region’s economic development, transportation upgrade and ethnic (民族的) unity,” Yang said.
