Could smells affect your lifespan? Female fruit flies (果蝇) without the ability to smell food live longer than other fruit flies．The sense of smell may be connected to the cellular ageing (细胞老化) process in many other living things  even people．Such connection has recently been found in both worms and flies．For example, scientists found that removing fruit flies' ability to smell made them live nearly 20 percent longer than flies with a sense of smell．

    They confirmed that food smells were the ones most likely to affect ageing, as nutrition (营养) and lifespan are known to be connected in many living things．To test the idea that food smells affect lifespan, they removed flies' ability to smell carbon dioxide, which is produced by some fly foods．They left the rest of the smelling system．

    This action had no effect on male flies, but the females lived 30 percent longer than normal．Removing the ability to smell CO₂ may stop flies getting information about food availability．This could mean that food is not enough, causing processes that encourage flies to survive．Scientists found that the female flies from stored extra fat and that both males and females immune (免疫) to CO₂ were stronger against the stress than normal flies．It is suggested that females may simply be easily influenced by the smells of CO₂ ．

    Scientists point out that people don't know whether ageing and smell are connected in animals and humans．But they clearly experience physical changes after smelling food．

With a habit of drinking coffee on weekends while doing schoolwork, Wu Zibo, a 17-year-old student from Beijing No. 1 High School, wanted to order a cup of Moutai-flavored latte ( 茅台味拿铁 ). "I wonder how my father's favorite Chinese strong drink would taste with my favorite coffee, " Wu told China Daily (中国日报).

Moutai-flavored latte craze shows a team-up business pattern (团队经营

模式) in China. The team-up between Kweichow Moutai and Luckin Coffee has interested many people. It sold 5. 42 million cups and made 100 million yuan just on Sept. 4, the first day it came out, China Daily reported. 

Moutai has tried many ways in recent years to be more creative, such as by bringing out Moutai ice cream and canvas bags. "This creative team-up lets Moutai make its brand（品牌) younger, "Li Honghui, a marketing director for drinks, shared with China Daily. "Through team-up, brands can make the market bigger, and bring more new things to buyers", added Li.

In 2023, China's team-up market will grow to over 100 billion yuan and may reach 300 billion yuan by 2025, according to China Quality Daily. However, wrong team-up may have undesirable results and even hurt brands. "The secret to making a team-up successful is about how good the products are. The brands should not just pay attention to getting the people excited, "said Li.

In 2013, Chinese President Xi Jinping offered to build a Silk Road Economic Belt (经济带) and a 21st Century Maritime (海上) Silk Road, which became known as the Belt and Road Initiative (BRI, "一带一路"倡议). The BRI has brought cultures together for over ten years. As the BRI continues to bring the world together, young people from the Belt and Road countries can see how it continues to develop and have a deeper understanding of it. We did a survey of 125 Chinese students. The following survey is about BRI in the eyes of the students. The diagrams (图表) below show the results.

Sometimes it can be very difficult to predict(预测) the result of your exams, whether you are in a secondary school or even a university. This is probably because exams are one of the most anxious things in education for students. Whether a student is confident in their abilities or not，exams can be often both predictable(可预测的) and unpredictable. If the worst does happen, failing the exams can be one of the most disappointed experiences for students, especially when they were not expecting to fail their exams. 

One way to deal with exam failure is to talk to people. Talk to your family, talk to your friends, discuss with them what you can do to get good grades. One thing you must remember is that failing your exams is not the end of the world. Exam failure is one of the many difficulties you'll have to overcome(克服) in your life, and there are always possibilities to learn from failure. After all, I' m sure most of you have heard of a famous saying, "Failure makes you stronger". Actually, it is really true. It gives you an understanding of what it means to fail, to lose, to receive a negative result that you may not have expected to get. In addition, from failure, you can learn why you fail. Then, next time, you can avoid this mistake, and can get better grades.

Do you understand your parents? It is difficult for many teenagers to understand them and deal with the relationships with their parents. But you can make it easier by using the following tips.

There are four good ways to improve your relationship with your parents. The first is respect. It is important to show respect to your parents. You haven't experienced your parents' lives, so you may not know that they are under great pressure(压力) with their work.

Second, there is trust. You should trust your parents as they trust you. If you learn how to trust, your life will be much easier.

Third, there is communication. When you have arguments, you'd better communicate with your parents and show them that you have the right to make your own decisions.

Finally, there is company(陪伴). Just as kids need their parents' company, parents also need company. Have you tried to comfort ( 安 慰 ) your parents when they felt down? Company is a good way to drive away the black clouds hanging over your family.

Your parents give all their love to you. Why not try your best to care about them effectively (有效地)?

 Hello, everyone! I'm Jessie. I'd like to tell you something about my school—NO. 1 Middle School! It's not big but beautiful. 

 There are four buildings in my school. The classroom building is in the middle. It's where we have classes and learn a lot of interesting things. There are ten classrooms on the first floor, eight classrooms on the second floor and two classrooms on the third floor. Next to the classroom building is the library. It's my favorite place in school because I can read all kinds of books there. I often spend my free time there, learning new things and getting lost in the stories. 

 To the right of the library is the sports field. We have PE classes and play sports there. It's a great place to have fun. I love playing basketball and volleyball with my friends. Behind the library is the art building. We have three art rooms on the first floor, and four music rooms on the second floor. I can draw pictures and play the piano there. 

 In a word, I love my school. It's a good place to learn and make friends. I'm excited to spend the next few years here!
