As a child, I was always told to “eat my greens”. These were the unappealing vegetables that sat on the edge of my plate. Peas, and green beans, all looked and tasted 1. Let's face it, when there were so many other delicious treats to2 why eat boring vegetables?

    Since then my taste buds have3and I'm also fully aware of the health benefits of eating fresh vegetables. But we still need 4 of the amazing goodness these green super foods give us. In the UK, a campaign has been 5 for several years to encourage us to eat our “5 A Day”—five portions of fruit and vegetables. That's6 evidence has shown there are significant health 7 to getting at least five 80g portions of a variety of fruit and vegetables every day.

    But I struggle trying to fit these five portions into my daily 8 partly because I have a sweet 9 and vegetables are, well, tasteless. Researchers have been 10 how to make eating vegetables more 11. They analysed the psychology behind our food 12 and found that most of us are 13 by taste. Brad Turnwald from Stanford University says that “studies show that people 14 to think of healthier options as less tasty for some reason.”

    In Europe, a project called VeggieEAT has also been trying to find ways to get people to 15 more vegetables. Project leader, Professor Heather Hartwell believes in 16 encouraging people into eating the right things. One idea has been to put a 17 of a tasty looking fruit on a supermarket trolley as a 18 about buying something from the fruit store. She says, “Choice is a really 19 thing. But making vegetables look attractive will increase their sales.”

    Certainly, eating “twisted citrus-glazed carrots” does sound tempting, even if it just 20like a carrot, but if it makes us eat more vegetables then that can only be a good thing for our health.

    The world is like a big trampoline(蹦床). We are all jumping on it. I have jumped to many places on this big trampoline. My family took me to Kenya and Israel. My community took me to Appalachia, North America, and I took myself to the Bahamas and Belize. How 1 can one teenager be to go to all these places！

    Each trip left a vivid picture in my mind. It 2 me that we are all living on one trampoline. Everything we do 3 everyone else. My first trip to Kenya was a shock! People walked to work, four hours each way. One picture 4 in my mind: a Kenyan woman at seven in the morning making her 5 to work, barefoot, down the side of a dusty road. I went to Israel a couple of years later. I found two races (种族) trying to jump on the same 6. In the village of Akko, I saw Israelis and Arabs working side by side. In Jerusalem, however, I found 7 holes in the walls of Israeli homes. In Appalachia, I saw people go to bed hungry. In Belize and the Bahamas, I realized how 8 our trampoline has become. Natural resources are running out. Animal life is in danger. We all live on the same trampoline. Every 9 we take sends ripples(波澜) across the trampoline. If everyone could understand how they affect one another, we would make the trampoline 10.

    I fell in love with Yosemite National Park the first time I saw it, when I was 13. My parents took us there for camping. On the way out, I asked them to wait while I ran up to E1 Capitan, a 1rock of 3,300 feet straight up. I touched that giant rock and knew2I wanted to climb it. That has been my life's passion ever since—  3the rocks and mountains of Yosemite. I've long made Yosemite my 4.

    About 15 years ago I started seeing a lot of 5, like toilet paper, beer cans, and empty boxes, around the area. It's 6me why visitors started respecting the place 7and treated such a beautiful home-like place this way.

    I tried 8trash (垃圾) myself, but the job was too big. I would9an hour or two on the job, only to find the area trashed all over again weeks later. Finally, I got so10it that I decided something had to change.

As a rock-climbing guide, I knew 11about organizing any big event. But in 2004, together with some climbers, I set a date for a 12. On that day, more than 300 people 13. Over three days we collected about 6,000 pounds of trash. It was amazing how much we were able to 14. I couldn't believe the15we made—the park looked clean!

    Each year volunteers come for the cleanup from everywhere. In 2007 alone, 2,945 people 1642,330 pounds of trash.

    I often hear people 17about their surroundings. If you are one of them, I would say the only way to change things is by 18rather than complaining. We need to teach by 19. You can't blame others 20you start with yourself.

    Recently, the Victorian Government brought in new rules. Victorian state schools will be banned from using facial recognition technology in classrooms unless they have the 1 of parents, students and the Department of Education.

    Students may be justifiably horrified at the thought of being 2 as they move throughout the school during a day. But a roll marking system could be as simple as looking at a tablet or iPad once a day 3 being signed off on a paper roll. It simply depends on the implementation. Trials have already begun in independent schools and up to 100 campuses across Australia. According to the developers, the technology promises to save teachers up to 2.5 hours a week by 4 the need for them to mark the roll at the start of every class. Many students now have smart phones that recognise faces right now. There are also 5 face recognition apps for Android phones and iPhones. So face recognition is already in our schools.

    And I argue that, like earlier technologies such as the motor vehicle and mobile phone, a strategy where adoption is managed to create the most good and least harm is appropriate. We shouldn't simply 6 it.

    We are now in a golden age of face recognition. The main reason for rapid adoption is that recognition 7 has improved significantly in recent years. The simple application of this technology proposed for schools is to collect the student roll call 8 for classes. This is a compulsory requirement imposed by the education department.

    However, 9 is often raised as an objection and this issue can never be dismissed lightly. Objections are mostly based on the collection and distribution of the photos. But every school 10 photos of their students already and schools have strict control over distribution. Such controls would necessarily be built into any school certified system. The only fundamental 11 of the process is whether a teacher or a computer recognizes the student.

    Face recognition technologies will become widely adopted across society over the coming years. Concerns over implementation and privacy may 12 adoption in some places, but the 13 will come in and will change business practices right across the world once that happens.

    In short, this technology has the ability to free up our time and reduce the costs. As with all new technologies, of course, face recognition 14 reasonable concerns. Constructive policies and dialog are the preferred way forward to gain the 15 benefit for society at large, and to make sure we do the least harm.

    Earthquakes are common; thousands of them happen each day. But most are too 1 to feel. During a 2 earthquake, there is often a great noise first. Then the earth 3 terribly and many houses 4 down. Railway tracks break and trains go 5 lines; a great many factories are 6; thousands of deaths are caused, and many more lose homes… 7 the great damage and deaths caused by the earthquake 8, other disasters such as fires often 9. More buildings are destroyed and more 10 caused.

    Man knows the 11 of a possible earthquake, and for centuries man has been making researches on earthquakes. More than 2, 000 years ago, 12, a Chinese scientist named Zhang Heng 13 a machine which could find out from which 14 the seismic waves had come, and this machine is still 15 by scientists today. Now we know much more about earthquakes and 16 they happen, but we still cannot 17 exactly when and where an earthquake will happen, and cannot 18 it from happening. So earthquakes are among the 19 disasters in the world.

    No one can stop natural earthquakes. 20, scientists can help stop earthquakes destroying whole cities and causing too many deaths.

At the age of 12, I started playing golf when my parents enrolled me in a junior camp at the local public course. From that moment, much of my life has been 1 the game. The aspect of golf that attracted me was the sense of 2 . There's always a chance of making something 3 happen, maybe breaking a personal record or potentially making a hole-in-one. 

When I decided to pursue journalism in college, I had to take a 4 from the game. I'd still go out 5 to play with friends, but for the first time since my teens, I was away from my community. 

My 6 for playing golf reawakened when a friend invited me to the Langston course, which 7 me of the courses where I grew up: a 8 spot for people of all working-class backgrounds, and a far cry from the private golf 9 , in which expensive memberships are a basic 10 . When I get paired up with strangers to play, it's usually more of a 11 crowd. 

Some of the best walks I've taken have been out on the golf course. It's where I 12 with old friends and meet new ones, who 13 me to practice and get better. We share experiences on the golf course that are 14 and laugh about for days after our rounds. 

The sense of community I've regained with golf goes beyond my imagination. My circle only seems to be 15 , and I'm eager to see what the future holds.
