Having bad feeling about world? “Cheer up.” says science writer Matt Ridley. “The world has never been a better place to live in, and it will keep on getting better both for humans and for nature.”{#blank#}1{#/blank#}

    It is reported that there are more than ten billion different products for sale in London alone. Even allowing for the many people who still live in poverty, our own generation has access to more nutritious food, more convenient transport, bigger houses, and better cars. {#blank#}3{#/blank#} This will continue as long as we use these things to make other things. The more we specialize and exchange, the better off we'll be.

2)Brilliant advances

    One reason we are richer, healthier, taller, cleverer, longer lived and freer than ever before is that the four most basic human needs—food, clothing, fuel and shelter—have grown a lot cheaper. Take one example. In 1800 a candle providing one hour's light cost six hours' work. In the 1880s the same light from an oil lamp took 15 minutes' work to pay for. {#blank#}4{#/blank#} Today it's half second.

3 )Let's not kill ourselves for climate change

    {#blank#}5{#/blank#} A child that dies from indoor smoke in a village, where the use of fossil-fuel (化石燃料) electricity is forbidden by well-meaning members of green political movements trying to save the world, is just as great a tragedy as a child that dies in a flood caused by climate change. If climate change proves to be mild, but cutting carbon causes real pain, we may well find that we have stopped a nose-bleed by putting a tourniquet (止血带) around our necks.

A. Ridley calls himself a rational optimist—rational, because he's carefully weighed the evidence.

B. Overreaction to climate change could prove just as damaging to human welfare as climate change itself.

C. Shopping fuels invention.

D. And, of course, we earn more pounds and dollars than any who lived before us.

E. In 1950 it was eight seconds.

F. It's high time that we took immediate action to fight climate change.

G. Here's how he explains his views.

    We all know the hard work that filmmakers and actors put in to provide us with entertainment, but it seems that even regular moviegoers like us have a big impact on how a movie turns out too.

    For decades now, film studios have used so-called test screenings（试映）to get feedback from members of the public before a movie comes out.

    While test audience members are usually asked to fill in a questionnaire after a screening, telling the film studio what they liked and didn't like, media giant Disney has come up with a more high-tech solution.

    According to a paper published this summer by the company's researchers, Disney is measuring test audiences' reactions(反应) by using special cameras placed inside cinemas.

    Pairing the cameras with custom(定制的) software, the company can track what each audience member is feeling at any point in the movie, from anger to joy.

    This works by mapping 68 different points on each audience member's face. The cameras can see in the dark, and the software can figure out a person's mood based on the slightest of facial expressions.

    It is hoped that this new method will allow more detailed feedback from test audiences. Rather than relying on audience members to recall their feelings after the movie's over, it can accurately read their reactions in real-time.

    Test screenings are highly valued in the movie industry, and several well- known movies have been greatly altered following feedback.

    Viewers of E.T. the Extra-Terrestrial(1982) would have left the cinema feeling a whole lot differently if it weren't for its test audience's feedback.

    "In one cut of the film that was tested, E.T. died instead of going home in his spaceship. You won't be surprised to hear that the test audience in question didn't warm to this ending at all," wrote media website Den of Geek.

    But for those of us who are concerned about privacy, the cameras won't be installed in public cinemas.

    After all, unless you're part of a test audience, being in front of the camera is best left to the movie stars.

    Today just as technology changed the face of industry, farms have undergone an "agricultural revolution". On the farm of today, machines provide almost all the power.

    One of the most important benefits will be the farm computer. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock (家畜) to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.

    Another technological advance which is still in the experimental stage is the robot, a real "mechanized hired hand" that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make big changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. The complete mobilization (活动) of the farm is far in the future, but engineers expect that some robots will be used before long.

    Do you intend to study at an American university? It takes a long time to get accepted at most American schools, perhaps as much as a year. That's why you should start choosing a school as soon as possible. It's a good idea to apply to several different institutions, so that you'll have a better chance of acceptance at one. You should start looking for information now, because the more information you have about each college, the better choice you can make.

    There are two good ways to get information you need. One is a general reference (参考) book, called Guide to American Colleges and Universities. The other good source of information is the catalogue (目录) published by each school.

    You can study the general guide in almost any American library. This book has many useful statistics, such as the number of students, the average test scores for people accepted to the school, the number of books in the library, and the number of teachers. You can also find the address of each school in this book.

    Although the general guidebook has helpful information, some of the facts may be out-of-date. For example, many schools raise their tuition every year. Since you'll need to know what your education will cost, out-of-date information will not be good enough. Also, schools sometimes change their requirements for entrance. To be sure that you are getting present information, write to the university and ask for its catalogue. The catalogue has more detailed information. For example, the catalogue can tell you if there is a special foreign student advisor, what kind of courses are offered, and what kind of housing is available. Some universities have dormitories, but at others you have to find your own place to live.

    With all of this information, you should be able to pick out several good schools.

    Keeping fit often means sharing a busy pathway with cyclists, runners and walkers, but imagine facing the task of doing it all without being able to see or hear. It is a challenge many disabled athletes face, unless someone agrees to be their eyes and ears.

    Newly formed group Achilles Brisbane pairs vision－and hearing－impaired（视觉和听觉受损的）athletes with a person who would like to guide them.

    “When we go out, we're always going out into an unknown course,”said Achilles Brisbane president Jane Britt, who is both vision and hearing impaired. “It's much less frightening to have someone beside you that has full hearing to listen for you and tell you what's there.”

    Ms. Cullen and Ms. Britt meet up most Saturday mornings to take part in the free five－kilometer Southbank park run. Their partnership is built on trust, but Ms. Britt said that it took time to develop.

    Ms. Britt said it took an unexpected storm for her to trust Ms. Cullen completely. “There was violent rain, my glasses were broken and we were walking together,”she said. “I suddenly had to tell her I couldn't see anything, and I was going to have to completely trust her. From that time I knew it was going to work because she was so good about dealing with the special situation we both found ourselves in. ”

    Isabella Allen and her seeing-eye dog Tatum are two new additions to the Achilles programme. Ms. Allen kept active by running and cycling but found it difficult to keep going as her vision became worse. After nearly giving up completely, she worked up the courage to ask Brisbane to find someone to share a boat with her.

    Ms. Alien said the fear of not finding anyone to row with almost stopped her from reaching out to Achilles Brisbane. “But, they found people and matched me to them.”she said, “It's the best thing I've ever done. ”

    If you frequently travel for business, Staybridge Suites offer you a range of home comforts. Four recent visitors to Staybridge Suites explain why they booked, what they enjoyed and what made them want to return.

Claire Metcalf

    "The concept is great, but the staff are the ones who really make it." she says. "It takes a lot of discipline to always be friendly, but the staff at Staybridge Suites do that. They genuinely care about you. "

Andrew Roberts

    "One of the best things is having my own kitchen. I often end up working late and I don't fancy eating in a restaurant on my own, so cooking for myself is a big drawcard. "

    "The main thing for me is being able to cook and have my own little flat. The staff are amazing. It is great to be recognized by them, "he says.

Pauline Robinson

    "What I love about it is the way that you are treated by the staff," she says. "Some of the staff have been there all that time and they do look after you well. As a woman staying on my own, it is reassuring that they look out for you, and recently when I was poorly depressed they even brought things I needed to my room. "

Ryan Ruckledge

    "The fully-equipped kitchen is great. I always have a one-bed apartment so I have a separate kitchen and dining room and I'm able to relax and cook some meals. Eating out can feel a bit much when you do it day in and day out—it makes you hate what you do—and I don't want that. "
