1 . If you were to throw, say, a banana peel out of your car while driving along the motorway, that would be a completely harmless action, due to the fact that it’s part of a fruit — right? Actually, no. A banana peel can take up to two years to be naturally processed, and with a third of motorists admitting to littering while driving, that’s a whole lot of discarded banana peels. An orange peel and a cigarette butt has a similar biodegrading (生物降解) term to that of a banana peel, but tin cans last up to 100 years; and plastic bottles last forever, as do glass bottles.
Despite the fact that longer-lasting materials will serve to damage the environment and its animals for longer, we can’t merely measure the severity of a certain type of rubbish by its lifetime. For example, despite having a fairly short length of biodegrading time, more than 120 tons of cigarette-related litter is discarded in the UK every day.
It’s not a cheap habit either: to keep our streets clean annually costs UK taxpayers £500 million, and when you include our green spaces, that goes up to £1 billion. So, it’s not surprising that if caught fly-tipping you could face a £20,000 fine or even jail time and, if you disposed of something dangerous, the court could give you five years to serve. Regardless of how severe these punishments might seem, however, among the reported cases only 2,000 were found guilty out of 825,000, so we still have some way to go in making sure people obey the rules.

2 . The populations of common animals are just as likely to rise or fall in number in a time of accelerating global warming as those of rare species, a study suggests.
Until recently, scientists were still accumulating data on how animal populations were shifting over time globally across the different regions of the planet.
Making use of the newly available data, a team of University of Edinburgh researchers studied nearly 10000 animal populations recorded in the Living Planet Database between 1970 and 2014 to provide a new perspective on animal population change. These include records of mammals, reptiles, sharks, fish, birds and amphibians.
The team found that 15 percent of all populations declined during the period, while 18 percent increased and 67 percent showed no significant change. Amphibians were the only group in which population sizes declined, while birds, mammals and reptiles experienced increases. The overall decline in amphibians makes them a priority for conservation efforts, researchers say, as their loss could have knock-on effects in food chains and wider ecosystems.
Gergana Daskalova, of the University of Edinburgh’s School of GeoSciences, who led the study, said, “We often assume that declines in animal numbers are prevalent everywhere. But we found that there are also many species which have increased over the last half of a century, such as those which do well in human-transformed landscapes or those which are the focus of conservation actions.”
Dr. Isla Myers-Smith, also of the School of GeoSciences, who co-authored the study, said, “Only as we bring together data from around the world, can we begin to really understand how global change is influencing the biodiversity of our planet.”

3 . Most of the efforts aimed at reducing climate change centering on reducing the use of fossil fuels. But a new study warns that pollution caused by the world’s food production system is also a major driver of rising temperatures on the planet. The study found that if the world food system stays on its current growth path, it will produce nearly 1.4 trillion tons of greenhouse gases over the next 80 years. That pollution is expected to come from chemical fertilizers used in agriculture, mismanaged soil, food waste and methane (甲烷) gas released from cows and other animals.
Researchers from the University of Minnesota and the University of Oxford in Britain led the study, which recently appeared in the publication Science. The researchers predict that even if fossil fuel emissions (排放) were halted now, emissions from the world food system would make it impossible to reach current international climate change targets. They say that emissions from food production alone could push world temperatures past 1.5 degrees Celsius by the middle of this century and above 2 degrees Celsius by the end of the century.
A main goal of the 2015 United Nations Paris Agreement on climate change is to keep rises in the Earth’s temperature during this century to between 1.5 to 2 degrees Celsius. The U. N. has said that in order to stay below the 1.5 Celsius level, emissions must fall at least 7.6 percent each year through 2030.
The new study calls for immediate improvements in farming practices, as well as changes in what we eat and how much food we waste to help reach the Paris Agreement goals.

4 . Kailash knows the thought of public speaking is enough to send many people into a cold sweat-he’s been there. He made his first public speaking in Year 4 at a time when his confidence had been broken down by a bully(霸凌者). He still gets scared thinking about it today because he had to go in front of the whole class and recite a poem that made no sense whatsoever.
By Year 5, Kailash started to hone his skills with the help of his father so that he could run for school captain in Year 6, but he was very shy and he couldn’t speak very well. So he started to practise and practise. That’s a good point for kids-they don’t apply for leadership positions because they are nervous, even though they’d make great leaders.
Kailash went on to score the role of vice-captain, despite his speech not going to plan. He made a joke but he made it so poorly that they laughed at him, not at the joke. But he said making mistakes is a key part of the public speaking learning. Things like that happen and it’s OK. You have to have the confidence to be OK with that and the resilience(弹性)to get back up.
Kailash, who counts a 4000-strong Sydney Opera House crowd and a community-based TEDx event among his public speaking credits, said public speaking skills have huge benefits in day-to-day life, from interacting with teachers to going for a job interview. Public speaking teaches young people to be comfortable in themselves. So it teaches you about self-esteem, to accept who you are. Making eye contact and smiling to connect with your audience are other key steps in pulling off public speaking, along with wearing something that makes you feel comfortable and confident.

5 . Belly fat（stomach fat） has long been thought to be especially bad for your heart, but now, a new study adds more evidence to the idea that it may also be bad for your brain.
The study, from the United Kingdom, found that people who were overweight and had a high waist — to — hip ratio （a measure of belly fat） had slightly lower brain volumes （容量），on average, compared with people who were just over weight or had a healthy weight. Specifically, belly fat was connected with lower volumes of gray matter, the brain tissue （组织）that contains nerve cells.
“Our research looked at a large group of people and found obesity （肥胖）,specifically around the middle， may be linked with brain shrinkage （萎缩），” lead study author Mark Hamer, a professor at Loughborough University, said in a statement.
Lower brain volume， or brain shrinkage， has been linked with a higher risk of memory recession， which leads to being forgetful.
The new findings, published on Jan. 9 in the journal Neurology ， suggested that the combination of obesity （as measured by body mass index, or BMI） and a high waist—to—hip ratio may cause brain shrinkage.
However, the study found only a connection between belly fat and lower brain volume, but couldn't prove that belly fat actually caused brain shrinkage. It could be that people with lower volumes of gray matter in certain brain areas are at a higher risk of obesity. Future studies are needed to find out the causes for the connection.
1. What can we infer about belly fat from the new study?| A．Belly fat may have a bad influence on our brain. |

6 . Yangsigang Yangtze River Bridge, the double-deck suspension (悬浮) bridge with the longest span in the world, opened to traffic on Tuesday after five years’ construction, according to a statement from the constructor.
It is reported that the bridge is 4. 13 kilometers long, with 12 lanes in both directions on the main I bridge. It is a long-span suspension bridge with the largest volume in the world, China Railway Major Bridge Engineering Group said. The bridge connects the Hanyang and Wuchang and its opening will ameliorate the urban expressway system, relieve traffic pressure across the river, and drive development in the area, according to the company.
On both sides of the upper deck of the bridge, there is a two-meter-wide footpath, with eight rest and sightseeing areas, where people can enjoy the river scenery. The lower level is designed with two non-motorized lanes, each 2. 5 meters wide. A 1. 5-meter wide walkway is also a feature of each side of the floor so pedestrians (行人) can walk on the lower level without getting caught in the rain.
Chief designer of the bridge, Xu Gongyi, said, “Considering navigation and traffic volume, the main span of the bridge is 1, 700 meters, which is the second-largest in the world and also the largest in bridges of double-deck structure.”
According to Luo Ruihua, project manager of the bridge, the Yangsigang Yangtze River Bridge has set several records in the process of its construction. The designed tension of each of the two main cables (钢索) is 65, 000 tons.
From 2014 to 2019, builders have shown the world the speed of China. The bridge not only enhances Wuhan’s reputation as a “bridge museum”, but also represents a super project of a new era.

7 . Have you ever wanted to stop eating something sweet but you just couldn’t? Is it the first thing you do when you get home from school to look in the biscuit tin? Can you eat a huge bar of chocolate all by yourself? Can you say “no” to sweets at parties? If you can’t, then there is a reason … perhaps you are a sugar addict! Does that sound funny? Well, doctors say that people who eat sweets regularly can easily become addicted to sugar. What’s more, most sugar addicts don’t even realize that they are addicted! Sugar addiction is serious because it can really damage your health. Doctors say that we should eat food which is healthy such as fresh fruits and vegetables, and that we shouldn’t eat a lot of sugar, fat or fast food. But sugar addicts can’t follow this advice. They know they must stop eating sweet food, but they can’t.
So what can you do if you think you are addicted to the taste of sugar? Well, here is some advice:
Eat some fresh fruits when you really want something sweet to eat.
Cut down some sweet food slowly.
Don’t try to stop eating it at once.
You have to tell your parents. If they know, they will help you.

8 . Yesterday was my final day as an English language assistant in Paris. I have loved every single moment of my time teaching, and could not have asked for a better school, with the most wonderful students. When applying to be a language assistant. I was a little worried about what the students would be like.
Upon arrival, I found the easiest approach to creating lesson plans was to focus on what was happening right here and now. For example, when it was Halloween in the UK, I found plenty of brainchildren to help me teach my students all about the different cultures and traditions they do not have in France. They loved it! And now, seven months later, it's all over!
The whole experience has been amazing. I highly recommend being a language assistant. I don't want to become a teacher，and I didn't before I arrived, but the skills and experience I have gained from these entire seven months of working is indescribable. Now, I'm finding myself still walking down the street and having ideas pop into my mind and saying, “Oh! 1 can teach mv class about that next week!” It's very bizarre(异乎寻常的).
I think this first week of having no work and not needing to think of potential lesson plans will be the hardest，and it was surprisingly difficult to say goodbye to most of my classes. But deep down，I know that my time teaching in Paris has given me so much experience and a completely new outlook on how to communicate with younger people with different needs and learning styles.

9 . I have always found the Chinese to be a very polite people. In particular, Chinese frequently compliment (称赞) foreign friends on their language skills, knowledge of Chinese culture, professional accomplishments, and personal health. Curiously, however, Chinese are as loath to accept a compliment as they are eager to give one. As many of my Chinese friends have explained, this is a sign of the Chinese virtue of modesty.
I have noticed a difference, though, in the degree to which modesty is emphasized in the United States and China. In the US, we tend to place more emphasis on “seeking the truth from fact”, thus, Americans tend to accept a compliment with gratitude.
Chinese, on the other hand, tend to reject the compliment, even when they know they deserve the credit or recognition which has been awarded them. I can imagine a Chinese basketball fan meeting Michael Jordan of the Chicago Bulls. He might say, “Mr. Jordan, I am so happy to meet you. I just want to tell you, you are the best basketball player in the world; you’re the greatest!” to which Jordan would probably respond, “Thank you very much. I really appreciate it! I just to try to do my best every time I step on the court.” If an American met Deng Yaping, China’s premier pingpong player, he might say much the same thing: “Ms. Deng, you’re the best!” but as a Chinese, Deng would probably say, “No, I really don’t play all that well. You’re too much kind.”
Plainly, Americans and Chinese have different ways of responding to praise. Ironically, many Americans might consider Ms. Deng’s response the less modest, because it is less truthful—and therefore less sincere. Americans generally place sincerity above manners; genuine gratitude for the praise serves as a substitute for protestations of modesty. After all, in the words of one of my closest Chinese friends, modesty taken to the extreme is pride.

10 . A teenager of 17 walks into a corner store and grabs a Coca-Cola, but the cashier refuses to sell it to him because he is underage. That rule is expected to soon become reality in parts of Mexico, as lawmakers in several states push legislation (立法)to keep junk food away from children. know it can sound a bit difficult but we have to take action now," says Lopez, a lawmaker in Oaxaca's Congress.
More than 70,000 Mexicans have died from COVID-19, the world's fourth-highest recorded death toll, tracked by Johns Hopkins University. 89% of those who died in Mexico had an underlying medical condition such as obesity, diabetes (糖尿病)，high blood pressure and heart problems. That has led to a new urgency to change diets so that the younger generation doesn't suffer those illnesses.
The critics, however, say the leaders are using preexisting health conditions in COVID-19 patients to distract from a weak government response to the virus outbreak. Yet few people would deny that the country consumes large amounts of sugar-sweetened drinks and processed snacks with little nutrition --- or that Mexico has a major weight problem.
Oaxaca's governor approved the state's junk food prohibition last week. Legislators still have to complete the legal systems, and punishment could include fines and even jail. Lopez says legislators from all over the country have called her for advice. Many other states are debating a junk food ban. However, a nationwide law would not be easy. "There are powerful commercial interests that least want it to happen, but we must prioritize the well-being of our children," Lopez says.
1. What is Lopez 's attitude towards the junk food?| A．Negative. | B．Neutral. |
| C．Positive. | D．Indifferent. |
| A．Keep distance. | B．Avoid illnesses. |
| C．Break away. | D．Shift attention. |
| A．Selling children junk food has been banned nationwide in Mexico. |
| B．Most Mexicans who died of COVID-19 had other health problems. |
| C．The younger generation doesn't suffer any weight problems. |
| D．People who break the prohibition in Oaxaca will only be warned. |
| A．Teenagers. | B．Legislators. |
| C．Soft drink companies. | D．State governors. |
