1 . Bangladesh's floating gardens, built to grow food during flood seasons, could offer a continuous solution for parts of the world which are likely to suffer from flooding because of climate change, a new study has found.
Bangladesh's floating gardens began hundreds of years ago. The gardens are made from native plants that float in the rivers and operate almost like rafts (筏), rising and filling with the waters. Historically, they were used to continue growing food during rainy seasons when rivers were filled with water.
The farmers layer the plants about three feet deep, creating a version of raised-bed gardens that float in the water. Then, they plant vegetables inside those rafts. As the raft-plants rot away, they release nutrients, which help feed the vegetable plants.
But as climate change affected the volume of water in those rivers, the researchers wanted to understand whether Bangladesh's floating gardens could be a continuous farming practice. They interviewed farming families and found strong evidence that floating gardens provide stability, both in the amount of food available to feed rural populations and in a farming family's income.
They found that farmers typically use hybrid (杂交) seeds, which must be repurchased each year, to grow a diverse range of vegetables in the floating gardens. The gardens are also sensitive to pests, so farmers end up spending some money on both pesticides and fertilizers. But even with those expenses, they found, benefits outweighed costs. One farmer told the research team that he earns up to four times as much money from the gardens as from traditional rice fields.
However, before gaining profits, farmers often take out high-interest loans (贷款) to cover the investment costs of filling the beds and stocking them with plants. Luckily; there are also lower-interest loans from responsible government or non-governmental organizations, which could ease that burden.

2 . Beijing is a rather strange city to many western people. One of my foreign friends told me that when he came to Beijing, at first he couldn't understand why most people wear masks when spring comes to Beijing. He thought people wanted to keep their appearance a secret. Well, one of the symbols of spring coming to Beijing is that more and more people start wearing masks. The reason for it is the arrival of so called “sandstorms”.
It is said that each year sandstorms hit Beijing 4 to 5 times. The sand is brought to Beijing by wind from the western part of China. Tons of soil and dust travel hundreds of miles and blanket Beijing's streets, parked cars and apartment buildings. You would be amazed to see the ground has turned yellow overnight. The storm is so violent that you do not want to have a conversation with your friend on the road. If you open your mouth and then you close it, you may have the raw taste of sand in your mouth.
People in Beijing hate those storms. Sandstorms make the traffic jam in rush hours even more unpredictable, because the drivers have to drive slowly in order to have a clear view of the road conditions. Young students also hate sandstorms because whenever there is a sandstorm, they are not allowed to have any activities outside the classroom. It is so boring to sit in the classroom all day and the youngsters are so eager to go out and do some sports.
It is said that the closest desert is only 80 kilometers away from the city center.There is definitely much more to do for the local government to deal with the environmental problem.
1. Why do people in Beijing wear masks in the spring?| A．Because they are rather strange. |

3 . 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.
1. What does the underlined word “discarded” in para1 mean?| A．Harmless. | B．Processed. | C．Thrown. | D．Long-lasting. |
| A．Glass bottles. | B．Tin cans. | C．Cigarette butts. | D．Banana peels. |

| B．Quite a few people were found guilty of illegally littering. |
| C．Every year UK taxpayers spend £500 million keeping streets free of dirt. |
| D．Cigarette-related litter and peels can be ignored for their fairly short lifetime. |
| A．To inform readers of different biodegrading terms. |

4 . 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.”

5 . 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.

6 . The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health. There are plenty of “energy drinks” on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!
But after a careful check you may find that most energy drinks have lots of caffeine(咖啡因) in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake.But be careful not to drink too much. Caffeine makes your heart beat fast. Because of this, the International Olympic Committee(OC) has limited(限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems.Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

7 . 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. |

8 . 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.

9 . 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.

10 . 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.
