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 . Alan Tong was the worst driver in town. He had an accident of some kind almost every week.
Alan lived with his mother. His mother was always worried about him. Every day she worried that police would appear to arrest him. This wasn’t a foolish worry because they usually visited Alan’s house about once a week to send a speeding ticket or to serve him notice to appear in court (法庭).
Most of his accidents were caused by his carelessness. He drove through red lights. He turned left or drove at night without proper lights. He overtook other cars on hills. In short, there wasn’t a traffic rule that Alan had not broken, and he had had so many accidents that it was a surprise that he was still alive. But luckily for Alan, he had never hurt anyone in his accidents or even gone to the hospital.
Although Alan wasn’t popular with the police, he was very popular with his lawyer. Alan’s lawyer, Mr. Tsui, had earned a lot of money from Alan’s cases and always felt very excited when he saw Alan coming into his office.
One day Alan was working in the garage, painting his car when his mother walked in. “What are you doing?” his mother asked.
“Painting my car,” Alan replied.
“I can see that,” his mother said, “but why are you painting one side of the car red and the other side blue?” “Because every time I have to go to court for a traffic crime, there are always two witnesses (目击证人) . “What color was the car?” the judge always asks, and the two witnesses always give the same answer. Well, in the future, one witness will say it was blue. Mr. Tsui will then say to the judge, “Your honor, the witnesses cannot even agree on the color of the car involved in the accident.” And the judge will have to dismiss the case against me.

3 . Diwali（Deepavali）is a festival of lights observed in October or November each year in Canada. During the festival, various community groups, businesses, schools and associations celebrate it in different ways. Some companies have Diwali dinners and some communities organize gatherings that feature firework displays, dances, street lighting, and plays.
Many women wear fine jewelry and silk outfits to celebrate Diwali. Some women and girls use Mehendi, a dye decoration which can last a limited time, on their palms, and then they will finally get colorful hand paintings. Many homes that celebrate Diwali have various types of sweets, salty and spiced food as well as Diwali herbs （香料）. Various lights, candles and sparklers are lit inside and outside homes, particularly in courtyards, on Diwali. Diwali is not a nationwide public holiday in Canada but it is a prevalent festival celebrated in many towns and cities. There may be traffic jams and parking places may be full in areas where events are held to celebrate Diwali. Some Indian businesses may close early on Diwali.
Diwali is called the "Festival of Lights" and is celebrated to honor Rama, a hero who once fought and won a battle against the demons（恶魔）. In the past, people lit their houses to celebrate his victory over demons（light over darkness）. At the same time, every household did careful and complete cleaning at home in advance. It is believed that the goddess of happiness and good fortune, Lakshmi travels around the Earth on this day and enters the house that is pure, clean, and bright.
Diwali celebrations may vary in different communities but its spiritual meaning is generally "the awareness of the inner light". As the word “Deepavali” means “a row or cluster of light”, the festival symbolizes the victory of righteousness and the lifting of spiritual darkness.

4 . A painting stamped with more than 4.8 million fingerprints and cost over 80, 000 yuan in paper has set the Guinness World Record for the largest fingerprint painting.
The fingerprint painting, named Descendants of the Dragon, was created by Kuang Xianpeng, a 35-year-old painter from Zhuzhou, Hunan Province. It describes a mix of nine Chinese dragons and six arts in ancient Chinese culture.
With a surface area of 1195. 14 square meters, 51. 526 meters long and 23. 195 meters wide, the whole painting used 685 pieces of xuan paper and took Kuang over two years to complete. It also took 40 volunteers two whole days to lay out the painting for Guinness certification officer to measure.
Kuang said it was a very arduous journey, and he had used up all his spare time to finish the work. “It was very hard to master the amount of strength you put in your fingers, ” he said. “You can’t press too hard or too light. Otherwise, your prints will blur. I have wasted over 300 pieces of paper due to blurred fingerprints. ”
The Guinness certification officer Luo Qiong said this world record wasn’t easy to earn. She said each fingerprint must be clear, the painting must have more than four different colors, and the distance between each fingerprint mustn’t be more than 1 centimeter.
The world record for this category had been broken 15 times since 2014, with the previous one set by an Indian with a work measuring 1, 188 square meters.
Before this painting, Kuang had spent 14 years in drawing a pen-and-ink painting of 247 meters long and 1. 6 meters wide, telling stories of historical myths. He also said he would never stop exploring more creative works.

5 . It’s nothing new that you can find many files or services you can download or use from the Internet. The question is: Is downloading legal or not? In most cases the answer is negative, because sharing and downloading are illegal. Of course, you can find files for legal downloading, but you have to pay for them.
It seems innocent if you click on the download mark, but it isn’t. It should be compared with stealing in a store. Would you steal a magazine, an MP3player or a car? Downloading from the Internet is a theft, and sharing files, once you have stolen them, only makes it wore. For example, if everybody only downloaded, movies wouldn’t make money and the studios wouldn’t invest millions of dollars to make new ones.
Many people may think it better, easier and cheaper to do downloading. I think, that is the main reason why Internet users prefer sharing something to buying them. In the modern world we love convenience and what could be more convenient than getting music, films and games without having to leave your house? You don’t need to pay for what you get, there is no registration, and you don’t have to wait until shops open or the CD/DVD you want is posted to you. However, you could be in big trouble if you are caught. You could go to prison as a result of acting unlawfully, but so far only a tiny amount of people have been charged for downloading illegally. The majority of people who download illegally, and use the files for their personal use, will not get in trouble. And that's why it’s important for people to understand what the long-term consequences are if they don’t want to pay for their music, films and TV. Will film and music companies still spend millions of pounds every year if they have no chance of making a profit? The answer is plainly “no”.
Finally I would like to say that the Internet offers a lot of services for money, but people will always try to get them for free. To summarize my thoughts, I’d like to highlight that illegal downloading is both unfair towards producers and dangerous for those who practice this kind of activity. You have to decide whether to buy or download.

6 . New research suggests that dogs might be able to help save diseased citrus trees.
A group of scientists trained dogs to use their sense of smell to detect a crop disease called citrus-greening. The disease has affected orange, lemon and grapefruit trees in the American states of Florida, California and Texas.
The dogs can detect the disease weeks to years before it appears on tree leaves and roots, the researchers report. A study on their findings was published recently in the Proceedings of the National Academy of Sciences. The report says using dogs is also faster, less costly and more exact than having people collect hundreds of leaves for lab analysis.
Timothy Gottwald is a researcher with the U. S. Department of Agriculture and a co-writer of the study. He told The Associated Press, “This technology is thousands of years old-the dog’s nose. We’ve just trained dogs to hunt new prey.”
Citrus-greening is caused by a bacteria (细菌) that is spread by a tiny insect that feeds on the leaves and stems of citrus trees. Once a tree is infected (感染), there is no cure. The disease has also hurt citrus crops in Central and South America and Asia. In one experiment involving grapefruit trees in Texas, trained dogs were correct 95 percent of the time in telling the difference between newly infected trees and healthy ones. “The earlier you detect a disease, the better chance you have at stopping an epidemic (流行病) by removing infected trees,” Gottwald said.
Matteo Garbelotto studies plants at the University of California, Berkeley. He says the new research shows that dogs can detect an infection well before current methods. Garbelotto has been involved in similar research but had no part in the new study.
Laura Sims is a plant scientist with Louisiana Tech University. She praised the steps taken to find out if the dogs were detecting the bacteria itself or a plant’s reaction to an infection. To do that, the researchers infected different kinds of unrelated plants with the bacteria in a laboratory. The dogs were still able to pick out the infected plants.
Gottwald said, “You’ve seen dogs working in airports, detecting drugs and explosives. Maybe soon you will see them working on more farms. ”
1. According to the research, trained dogs can ________.| A．help infected trees recover from diseases | B．recognize a crop disease in its early stage |
| C．cause fruit trees to grow faster than usual | D．reduce the cost of planting some fruit trees |
| A．Infected plants. | B．Fruit trees. | C．Tiny insects. | D．Favourite foods. |
| A．To further prove the findings. | B．To explore the plant diseases. |
| C．To present different opinions. | D．To discover a plant’s reactions. |
| A．Doubtful. | B．Positive. | C．Indifferent. | D．Curious. |
7 . Two of the saddest words in the English language are “if only”. I live my life with the goal of never having to say those words, because they convey regret, lost opportunities, mistakes, and disappointment.
My father is famous in our family for saying, “Take the extra minute to do it right.” I always try to live by the “extra minute” rule. When my children were young and likely to cause accidents, I always thought about what I could do to avoid an “if only” moment, whether it was something minor like moving a cup full of hot coffee away from the edge of a counter, or something that required a little more work such as taping padding (衬垫) onto the sharp corners of a glass coffee table.
I don’t only avoid those “if only” moments when it comes to safety. It’s equally important to avoid “if only” in our personal relationships. We all know people who lost a loved one and regretted that they had foregone an opportunity to say “I love you” or “I forgive you.” When my father announced he was going to the eye doctor across from my office on Good Friday, I told him that it was a holiday for my company and I wouldn’t be here. But then I thought about the fact that he’s 84 years old and I realized that I shouldn’t give up an opportunity to see him. I called him and told him I had decided to go to work on my day off after all.
I know there will still be occasions when I have to say “if only” about something, but my life is definitely better because of my policy of doing everything possible to avoid that eventuality. And even though it takes an extra minute to do something right, or it occasionally takes an hour or two in my busy schedule to make a personal connection, I know that I’m doing the right thing. I’m buying myself peace of mind and that’s the best kind of insurance for my emotional well-being.
1. Which of the following is an example of the “extra minute” rule?| A．Start the car the moment everyone is seated. |
| B．Leave the room for a minute with the iron working. |
| C．Wait for an extra minute so that the steak tastes better. |
| D．Move an object out of the way before it trips someone. |
| A．keep her appointment with the eye doctor |
| B．meet her father who was already an old man |
| C．join in the holiday celebration of the company |
| D．finish her work before the deadline approached |
| A．abandoned | B．lacked |
| C．avoided | D．taken |
| A．To Keep Emotional Well-being | B．To Prevent “If Only” Moments |
| C．To Follow the Most Useful Rule | D．To Achieve the Peace of Mind |
