1 . Styrofoam, or polystyrene, is a light-weight material, about 95 percent air, with very good insulation (隔热) properties, according to Earthsource.org. It is used in products from cups that keep your drinks hot or cold to packaging material that protects items during shipping. With the above good features, Styrofoam still enjoys a bad reputation. It cannot be recycled without releasing dangerous pollution into the air. The U. S. Environmental Protection Agency says it is the fifth-largest creator of harmful waste.
But now the common worms which are usually disgusting can come to the rescue, specifically, mealworms. Scientists from the U. S. and China have discovered that mealworms can digest plastic. One mealworm can digest a pill-sized amount of plastic a day. Study co-author Wei-Min Wu says that in 24 hours, the plastic is turned into carbon dioxide.
Since Styrofoam has no nutrition at all, are the worms hurt by eating plastic? Much to the scientists’ surprise, the study found that worms eating Styrofoam were as healthy as worms eating bran (谷糠). The researchers will study the worm’s eating habits and digesting system, looking to copy the plastic breakdown but on a larger scale. Once the way can be put into practice, it will make a revolutionary difference to the disposal of plastic.
“Solving the issue of plastic pollution is important”, says Wu, a Stanford University environmental engineering instructor. After all, our earth is small and landfill space is becoming limited with too much garbage waiting to be dealt with, he says.
About 33-million tons of plastic are thrown away in the United States every year. Plastic plates, cups and containers take up 25 percent to 30 percent of space in America’s landfills. One Styrofoam cup takes more than 1 million years to recycle in a landfill, according to Cleveland State University.

2 . The United States seems to have become extremely enthusiastic about competition. The famous Scripps National Spelling Bee—an annual spelling contest—now allows kids who last in regional competitions but whose parents agree to pay an entry fee (费用) along with their own food and accommodation to compete. And while some kids are working for what they call a spelling “career”, others are approaching chess competitions, dance competitions, cooking or other passions that previous generations developed somewhat later in life.
I’m disturbed by the phenomenon (现象), which seems to be getting worse and more intense.
My teacher always warned us that competition is a destructive quality; that the goal is never to beat anyone else. I think he’ll be cheered by author Peggy Noonan’s idea that a lot of us are running our own races, trying to rise to the occasion and beat some past and limited conception of ourselves by doing something great.
I heartily agree. Instead of paying attention to the accomplishments or possessions of others, we need to focus on our own potential, our own growth and take pleasure in our own particular set of circumstances. The battle for life is not against anyone else but against the darkness inside that tries to bring us down. I wish you only well. Your good doesn’t reduce mine. Your bad gives me no pleasure
Ms. Noonan also suggests that “you’re running your own race alongside others running theirs, and in the same direction. You’re doing something great together.” If we stop worrying about what our neighbor is earning or driving, the size of his house, the success of his marriage, the accomplishments of his children, we can sit back and enjoy our own lives. And if we all focus on what we each can achieve, regardless of anyone else, we have a chance of working as one, of actually being united.
Competition divides us. There are winners and losers. But that’s a very limited picture of reality. It may apply to spelling bees and soccer matches and even in some college classes, but life isn’t about triumphing (战胜) over someone else; it’s about triumphing over ourselves. The only acceptable competition is one where we encourage each other to be the best human being possible, and that’s the only game where “everyone is a winner”.

 | Social Media Detox Today marks the last day of the Social Media Detox, Brenton High’s fundraising campaign for new sports equipment. At the start of the detox, over one hundred students had been persuaded to stop using social media, in ANY form, for seven days. This meant no messaging friends, no posting photos, no blogging — nothing. They had been promised money by family and friends for each day spent without using social media. They were excited. They were nervous. But could they do it? With the detox now finished, they’ve switched on their devices and they’re back online. I bet you’re as eager as I am to find out just how many have been motivated enough to last the full seven days! And what, if anything, has been learnt from the experience? | ||
 | I lasted two days. The detox was more difficult to tolerate than I had expected. I felt like I had lost an arm! Not eating for two days would have been easier! But on reflection, I can see how much of my time had been occupied with checking my phone. I’m now trying to spend less time online and more time picking up my hobbies. | ||
 | I lasted four days. On Monday, my classmate and I spoke about what we did at the weekend - it felt really strange not to already know what he had done. We would usually have posted pictures and updated our profiles. Doing the detox meant we had to talk and explain what we were doing and thinking! It made me realise the value of real contact that I had forgotten. | ||
 | I managed the whole week! At first, I really felt I was missing out. Then, instead of messaging my friend. I went round t her house. Without our phones, we had a proper conversation for over two hours, without being distracted by messages from other people. It felt so good! Then I decided to visit a different friend every day. By the fifth day, I wondered - was I really missing out by not constantly checking my phone to see what everyone else was up to? | ||
 | I did all seven days, too! To be honest, I didn’t find the detox too difficult, but I did give my phone to my dad to avoid giving in! My brother thought I should make full use of the time without my phone; so he took me to check out our local sports centre. An hour’s sport each day left me tired out and wanting to go to bed early. The detox made me healthier! | ||
 | I’m embarrassed to say that I threw in the towel on the first day! I knew there was a party happening that evening, but without access to social media I couldn’t remember where it was! In the end, I turned on my phone to check, but couldn’t resist having a quick look at my social media accounts. What’s worse, I then spent so much time catching up on news, I almost missed the party! | ||
 | The detox raised a total of $1,632.82 for new school sports equipment! Well done, everyone who took part! After reading the posts on this forum, it seems that something other than money has also been raised through the detox. Awareness of just how much we rely on social media can help us step away from it and communicate with each other better. | ||

4 . In today's world, online social media' has become more powerful and the most destructive thing over worldwide, although with time all generations have come to accept the changes social network has brought about, teenagers and young adults are the most enthusiastic users of these sites. According to various research studies in the field of online social networks, it has been revealed that these sites are impacting the' lives of the youth greatly. When using these sites such as Twitter, Facebook or Myspace, there are both positive and negative effects on the youth.
Firstly, social media helps the youth and any other user updated with what is happening around the world, and helps the teenagers stay connected and interact with each other even if they are many miles apart. This strengthens their relationship. Even if they finished school and moved to different locations, they stay connected and update one another.
In addition, social media sites have provided a platform whereby the youth can create groups and pages based on their common discipline and end up building connections and opportunities for their respective careers by updating different topics to discuss. Youth who have been interviewed say that social media has become their lifestyle and it makes their lives easier and more efficient.
While on the one hand social network sites seem to bring people together and stay connected, on the other hand it causes many physical and mental health problems such as eyes infection, back problems, etc. Other negative effects of social networking various people suggested included encouraging poor spelling and grammar, exposing underage to online predators (捕食者), allowing spread of misinformation that is seen as fact, decreasing productivity as those who are supposed to be working spend time in the sites to chat, providing a perfect platform for cyberbullying and providing details that increase risks of identity theft.
“The more social media we have, the more we think were connecting, yet we are really disconnecting from each other.” One researcher said.
In conclusion, social networking clearly portrays both positive and negative effects on the youth. It is the decision of individuals whether to use it in a right way or wrong.

6 . US Open Championships
The US Open has been in existence for more than 130 years. The first tournament was held in 1881 at the Newport Casino. It was called the US National Singles Championship. Entry was limited to only those clubs which were members of the United States National Lawn Tennis Association, and the competitors were all male, competing in both singles and doubles. Richard Sears won the men's championship and he went on to win the next six men's singles championships.
The Wimbledon
In 1875, the All England Croquet Club was troubled financially due to declining membership. A new sport called lawn tennis was gaining fast in popularity and taking away the members. Two years later, a new roller was needed for maintaining its lawns so the club proposed to hold a tournament to raise money. Twenty-two players entered that first Wimbledon tournament which was won by Spencer Gore in straight sets over W. C. Marshall. Two hundred spectators each paid a shilling to watch the final game, enabling the club to buy the needed roller plus some extra cash.
The French Open
The very first French Championship was way back in 1891, and the tournament has since grown into one of the four tennis Grand Slam tournaments we know today. The first competition was a one-day national championship which was won by a British. The competition was poorly attended by world class players. It took 24 years before it became fully international and an accepted tennis grand slam event. After the First World War, French tennis was achieving stature. Suzanne Lenglen was the predominant French player, winning the championships six times between 1920 and 1926.
The Australian Open
The very first tennis tournament ever played in Australia was held in January 1880, on the courts of the Melbourne Cricket Club. In 1905, the Australian Open was established as the Australasian Tennis Championship and was played at the Warehouseman's Cricket Ground in Melbourne. It became the Australian Championship in 1927 and the Australian Open in 1969. Women's events were added in 1922.

Bethany Hamilton has become a source of inspiration for millions through her story of faith, determination and hope. And now her story has become a major movie which is entitled Soul Surfer.
Born into a family of surfers on February 8, 1990, on the island of Kauai Hawaii, Bethany began surfing at a young age. At the age of eight, Bethany entered her first surf competition---- winning both the short and long board divisions and sparking a love for surf competition within her spirit.
On October 31, 2003, at the age of 13. Bethany was attacked by a 14-foot tiger shark while surfing just off the shore of Hawaii. Bethany said, “It came out of the blue. I had no warning at all; not even the slightest sign of danger on the horizon. The waves were small and inconsistent, and I was just kind of rolling along with them, relaxing on my board with my left arm dangling (悬摆) in the cool water. I remember thinking, ‘I hope the surf picks up soon...’”
“That's all it took: a split second. I felt a lot of pressure and a couple of lightning fast tugs(猛拽) .Then I watched in shock as the water around me turned bright red. Somehow, I stayed calm. My left arm was gone along with a huge piece of my surfboard...”
Her friends had to get her to the beach which took 20 minutes of paddling. After losing more than 40 percent of her blood and making it through several surgeries, Bethany was well on her way to recovery due to an unbelievably positive attitude.
In January 2004, Bethany made her return to surf competition and with no intention of stopping, Bethany continued to enter and shine in competitions. Initially, she adopted a custom-made board that was longer and slightly thicker than standard and had a handle for her right arm, making it easier to paddle, and she learned to kick more to make up for the loss of her left arm.
Just over a year after the attack, she took first place---- winning her first National Title. Now she competes with the world's best and travels the globe.

8 . Round and Round They Go
Space is becoming more crowded. On December 3, a Falcon 9 rocket made by Space X thundered into the sky. On board were 64 small satellites, more than any American company had launched before in one go. They have a variety of uses, from space-based- radar to the monitoring of radio-frequency- emissions.
These objects are part of the latest breed of low-Earth-orbit (LEO) satellites. This launch is just taste of what is planned. Space X and One Web, a communications firm, plan to launch satellites in their thousands, not hundreds. The pair are set to double the total number of satellites in orbit by 2027.
That promises to change things dramatically on Earth. LEO satellites can bring internet connectivity to places where it is still unavailable or unaffordable. This will also be a lasting source of new demand for the space economy. Morgan Stanley, a bank, projects that the space industry will grow from $350 billion in 2016 to more than $1. I trillion by 2040. New internet satellites will account for a half this increase.
For that to happen, however, three worries must be overcome. Debris(碎片)is the most familiar concern. As long ago as 1978, Donald Kessler, a scientist at NASA, proposed situation in which, when enough satellites were packed into low-Earth orbits, any collision could cause a chain reaction which would eventually destroy all space craft in its orbital plane(平面). The syndrome which bears Mr. Kessler's name weighs heavily on the minds of executives at the new satellite firms. Debris could cause entire tracts(广阔的一片) of space to be unusable for decades.
Solutions exist. One is to grab malfunction satellites and pull them down into Earth's atmosphere. Another is to monitor space more intensively for debris; a US Air Force program me called Space Fence is due to start in 2019. But technology is only part of the answer. Rules are needed to govern the safe disposal(清除) of old satellites from low-Earth orbit. The United States' Federal Communications Commission is revising its regulations with this in mind. Other countries should follow suit.
Cyber-security is a second, long-standing worry. Hackers could take control of a satellite and seal intellectual property, redirect data flows or cause a collision. The satellite industry has been slow to respond to such concerns. But as more of the world's population comes to rely on the infrastructure of space for access to the internet, the need for action intensifies.
The third issue follows from the first two. If a simple mistake or a cyber-attack can cause a chain reaction which wipes out hundreds of billions of dollars of investment, who is liable? Underwriters(保险商) are studying the plans of firms that wish to operate large numbers of satellites. But there is a long way to go before the risks are well understood, let alone priced.
As space becomes more commercialized mind-bending prospects open up: packages moved across the planet in minutes by rocket rather than by plane, equipment sent to other small planets, passengers launched into orbit and beyond. All that and more may come, one day. But such activities would raise the same questions as LEO satellites do. They must be answered before the space economy can truly develop.

9 . In 1957, Max Vernon Mathews wrote the first computer program called Music, which enabled a computer to create sound and play it back. He was then working as an engineer at Bell Laboratories in New Jersey. It enabled a large IBM computer to play a seventeensecond piece of music he had written.
The computer was so slow that it took an hour to play the seventeensecond piece of music. So Mathews moved the work to a tape player to play the music at a normal speed. He later said that the sound quality of the musical notes was not great, but the technical importance of the music was huge.
The science fiction writer Arthur C. Clarke visited Bell Laboratories in the 1960s. He heard a computer “sing” the song Daisy Bell on devices (设备) and learned about the programs developed by Mathews and other engineers. Clarke noted this technology in his book 2001: A Space Odyssey, which was later made into a movie.
Mathews continued creating other versions of the Music program. He became interested in how computers could help musicians outside recording studios. The Groove program he developed was the first computer program made for live performances.
He also developed an electronic device he called the Radio Baton, which looks like two drum sticks. It enables the user to control the speed and sound levels of orchestral music (管弦乐) played on a computer by moving the two sticks on a special electronic surface.
Mathews said he believed modern musicians were not making full use of the power of computer music. He said a violin always sounds like a violin. But with his Music, the way a violin sounds is unlimited. He did not want computer sounds to replace live music, but he hoped computers would one day be considered serious instruments.

| B．It can help make more sounds. |
| C．It will finally replace the violin. |
| D．It is more popular than live music. |
| A．He is the father of computer music. |
| B．His creation succeeded on the first try. |

How do students spend their spare time after finishing their homework? Watch TV, play computer games, or go outside to relax? Here's a good example.
Tim and Kerry Meek are both teachers. They live in the UK with their two daughters: eleven-year-old Amy and nine-year-old Ella. Recently, the Meek family has become the focus of the whole country after they completed 100 different outdoor activities in one year.
The Meek couple didn't want their children to spend all their free time in front of the TV and become "couch potatoes". So about one year ago, the Meeks decided that watching TV and playing computer games were not permitted. Instead, they set 100 tasks for the two girls to do outside. Although Mr. and Mrs. Meek are not outdoor activity fans, they took part in all the activities to encourage their daughters. It turns out that the two sisters really had a good time joining activities.
Every holiday and weekend, whether it's sunny, rainy or snowy, the Meeks' would set off to try the activities on their list, including hiking, sailing, climbing, skiing, and so on. The two little girls not only had a wonderful time, but also learned a lot of skills from the activities. They were even able to stand up in front of their school to give a talk for charity. "Our friends spend a lot of their free time doing things which are harmful to their health. Luckily, we've had the chance to experience something different." Amy and Ella also helped their parents to draw up a new list of challenges for the next 12 months.
