Insect numbers have decreased by half in some parts of the world due to climate change and intensive agriculture,a study has found.The combined pressures of global heating and farming are driving a "substantial decline" of insects across the globe,according to the UK researchers.

Lead researcher,Dr Charlie Outhwaite of UCL,said losing insect populations could be harmful not only to the natural environment,but to human health and food security,particularly with losses of pollinators(传粉昆虫)."Our findings highlight the urgency of actions to preserve natural habitats,slow the expansion of high-intensity agriculture,and cut emissions to reduce climate change," she added.

In the latest study,the researchers pulled together data on the range and number of nearly 20,000 insect species,including bees,ants,butterflies,grasshoppers and dragonflies,at about 6,000 different locations.In areas with high-intensity agriculture and substantial warming,insect numbers have decreased by 49%,compared with relatively untouched places that have so far avoided the most severe impacts of climate change,according to the research published in Nature.

But the researchers said there was some cause for hope.Setting aside areas of land for nature creates a refuge(庇护所) for insects,which need shade to survive in hot weather."Careful management of agricultural areas,such as preserving natural habitats near farmland,may help to ensure that vital insects can still survive," said Dr Tim Newbold,also of UCL.

Study researcher,Peter McCann,added,"We need to acknowledge how important insects are for the environment as a whole,and for human health and well being,in order to address the threats we pose to them before many species are lost forever."

(1)、According to Charlie Outhwaite,how can we stop losing insect numbers?
A、Give up developing agriculture. B、Take action to protect natural habitats. C、Highlight the importance of food security. D、Focus on reproducing all sorts of insects.
(2)、How did the researchers draw the conclusion in the latest study?
A、By analyzing data. B、By carrying out a survey. C、By doing experiments. D、By discussing questions.
(3)、What is Tim Newbold's attitude to preserving insects?
A、Worried. B、Hopeful. C、Doubtful. D、Indifferent.
(4)、Which of the following can be the best title for the text?
A、Some rare insect species dying out B、Natural habitats helping insects survive C、Insect decline bringing great damage to humans D、Climate change and farming driving insect decline

“Write All About It”

Centerville High School Essay Contest

Rules

1). Students are asked to hand in essays of 500 to 700 words of their own work. Any essay containing material copied from another source will be disqualified.

2). Manuscripts should be typed double-spaced, with the student's name, address, and grade level on a separate sheet of paper.

3). Essays must be turned in by 4:00 P.M. on November 30. They can be brought to Mrs. Elton in Room 104 or to Mr. Markham in the school library.

Essay-Writing Tips

1). Catch your reader's interest—Your opening should immediately pull your reader into your essay. Asking a question or starting with a story, or surprising statement are some good ways to do this.

2). Create a picture—Use active words that show your reader what is happening. Instead of telling your reader that “the room was disordered,” paint a picture using active verbs and lively adjectives.

3). Have a purpose—Well-written essays do more than just describe an event or express a viewpoint; they also communicate a message.

4). Check for mistakes—Read your paper over to check for mistakes. Ask another student to read your paper. Another pair of eyes will often spot a mistake you have missed.

5). Format your essay—Neatly type your essay on white paper. Choose an attractive cover for handing in. The computer lab will be open after school from 3:15 to 4:45 P.M. each day this month so that students can use the computers.

    Breakthroughs in science and technology are paving the way for modern cities to support bigger populations. Now, we see the most exciting urban innovations to show you exactly how they'll improve your city's infrastructure(基础设施).

Lighting Up The Night

    Anthony Di Mari dreamed up an electric tree to help irrigate public parks and light them at night. These electric trees contain a special infill (填充物) that collects water from rainfall. The water is then distributed through a shallow underground irrigation system with the help from the trees' swaying movement. An electric motor turns energy from the waving of the artificial trees into electricity, which is used to light up the trees' outer LEDs.

Thinking Outside The Box

    As more people flock to urban areas, city planners will need to get increasingly creative about how to satisfy residents' health and transportation needs within decreasing available space. One way to achieve this is by updating infrastructure to support biking and walking by building suspended(悬浮的) roundabouts like hovering in the Netherlands. By lifting bicycle and pedestrian traffic above busy roadways, cities can significantly decrease over-crowded traffic condition.

Waving Hello To Clean Energy

    Cities that don't receive enough sunlight may find an attractive alternative in wave power. Since ocean waves rarely experience disruption(中断), electric engines driven by their clockwork push-and-pull can reliably provide power throughout the year. Further, thanks to advances in wave power technology, engineers have been able to move wave power engines farther offshore, where the waves pack the most punch, making the engines extremely efficient. So in the future, heavily populated coastal cities may use wave to meet their energy needs.

Five years ago, when I taught art at a school in Seattle, I used Tinkertoys as a test at the beginning of a term to find out something about my students. I put a small set of Tinkertoys in front of each student, and said: "Make something out of the Tinkertoys. You have 45 minutes today-and 45 minutes each day for the rest of the week."

    A few students hesitated to start. They waited to see what the rest of the class would do. Several others checked the instructions and made something according to one of the model plans provided. Another group built something out of their own imaginations.

    Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, "But I'm just not creative."

"Do you dream at night when you're asleep?"

"Oh, sure."

"So tell me one of your most interesting dreams." The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. "That's pretty creative. Who does that for you?"

"Nobody. I do it."

"Really — at night, when you're asleep?"

"Sure."

"Try doing it in the daytime, in class, okay?"

    Dazha Crabs from Yangcheng Lake

    With the Mid-Autumn Festival coming, the time for crabs is around the corner! Dazha Crabs from Yangcheng Lake in China are believed to be the best freshwater crabs.

    “They are delicious, because the bottom of Yangcheng Lake is hard and the crabs grow strong by walking on such a hard surface,” said one sales manager in Suzhou.

    Li Lei, a crab lover from Beijing, said “It's very delicious! But there are too many fake Yangcheng Lake Dazha Crabs”.

    “Maybe the crabs from other regions can appear to be glistening green back, white belly after people wash them, but the golden fine hair on crab claws is still a point of pride and is exclusive to Dazha Crabs from Yangcheng Lake,” said the manager.

    The best time for enjoying them is during September and October of Chinese lunar calendar. “When the season for crabs arrives, the Dazha Crabs from Yangcheng Lake are flown to various cities so that people's appetites can be satisfied,” said the sales manager. “They are really expensive here, sometimes more than 320RMB/500g, 10% of my salary!” said Li Lei.

    Dazha Crabs are usually steamed or boiled for within 20 minutes before they come on the dinner table. They are often enjoyed with vinegar mixed with minced ginger to add flavor and get rid of the cold. People who are particular about how they eat crabs also need to have high-grade Shaoxing rice wine to warm their stomachs.

    There is much work required to eat crabs. So much shell!Most people use both hands and teeth while eating Dazha Crabs. “The eating way is not graceful or elegant,” said Huck. “However, some professionals of eating crabs can use tools to take all the meat out of the crab without damaging a single bite and the crab can be restored to its original shape if the empty shells are pieced together!” said Han Mei, another Dazha crab lover.

    When I was a very little child, I remember watching TV and seeing other children suffer in other parts of the world. I would talk to myself, "when I grow up, when I can become rich, I'll save kids all over the world."

    At the age of 17, I began my career here in America, and by 18, I started my first charity organization. I went on to team up with other organizations in the following years, and met, helped, and even lost some of the most beautiful souls, from six-year-old Jasmina Anema who passed away in 2010 from leukemia (白血病)—her story inspired thousands to volunteer as donors, to 2012 when my grandmother lost her battle with cancer, which is the very reason and the driving force behind the Clara Lionel Foundation (CLF). We're all human. And we all just want a chance: a chance at life, a chance in education, a chance at a future, really. And at CLF, our mission is to impact as many lives as possible, but it starts with just one.

    People make it seem too hard to do charity work. The truth is, you don't have to be rich to help others. You don't need to be famous. You don't even have to be college-educated. But it starts with your neighbor, the person right next to you, the person sitting next to you in class, the kid down the block in your neighborhood. You just do whatever you can to help in any way that you can. And today, I want to challenge each of you to make a commitment to help one person, one organization, one situation that touches your heart. My grandmother always used to say, "If you've got a dollar, there's plenty to share."
