A shark moving around the coastline is normal...

A shark moving around the coastline is normally a worrying sight，but this waterborne drone(无人机)threatens floating rubbish instead of people.

Developed by Dutch company RanMarine, the WasteShark takes nature as its inspiration with its whale shark-like mouth. Responsible for collecting waste, the drone will begin operations in Dubai Marina in November after a year of trials with local partner Ecocoast.

According to RanMarine, the WasteShark is available in both autonomous and remote-controlled models. Measuring just over five feet by three-and-a-half feet(1.5 meters by 1.1 meter)，it can carry up to 352 pounds of rubbish(159.6 kg)and has an operational battery life of 16 hours.

By 2016 there were approximately 150 million tons of plastic in the world's oceans. One paper from December 2014 estimated that over a quarter of a million tons of ocean plastic pollution was afloat.

"WasteShark also has the abilities to gather air and water quality data, remove chemicals out of the water such as oil，and heavy metals，and scan the seabed to read its depth and outlines，"said Oliver Cunningham, one of the co-founders of RanMarine. "Fitted with a collision-avoidance system, the drone uses laser imaging detection and ranging technology to detect an object in its path and stop or back up if the object approaches."

"Our drones are designed to move through a water system, whether it's around the perimeter(周边) or through the city itself. The drones are that last line of defense between the city and the open ocean," added Cunningham. "WasteSharks are operating in Dubai, South Africa and the Netherlands and cost $ 17,000 for the remote-controlled model and just under $ 23,000 for the autonomous model."

Dubai-based operator Ecocoast has two WasteShark drones. Co-founder Dana Liparts says they will clean waterfronts for clients including hotels and environmental authorities and that Ecocoast' intention is to have the collected rubbish recycled or upcycled. However, Liparts argues that cleaning waterways doesn't have a one-size-fits-all solution and requires a combination of new technology, preventative measures and changing people's attitudes towards littering.

1.What do we know about the WasteShark?

A. It can frighten sharks away. B. It is an ocean explorer.

C. It is a rubbish collector. D. It can catch fish instead of people.

2.What does Paragraph 4 mainly tell us?

A. The causes of ocean pollution. B. The dangers of using plastics.

C. The severity of ocean garbage pollution. D. The importance of ocean protection.

3.What will the WasteShark do with an approaching object?

A. Avoid crashing into it. B. Break it into pieces.

C. Swallow it. D. Fly over it.

4.Which of the following ideas does Liparts agree with?

A. The WasteShark should be used more widely.

B. More measures should be taken to make water clean.

C. The production cost of WasteSharks should be reduced.

D. People should take a positive attitude to new technology.

China is a country on the move- especially around its Lunar New Year holiday. This year, the holiday crush（客流量） promises to be even heavier than before.

Getting tickets to all those would-be travelers is a discounting challenge that annually tries patience.　 And it is the railway system that routinely is most unable to cope.　 Railways are the transport of choice for low-cost long-distance travel, and that's where the ticketing system routinely falls down.

Much of the criticism has, focused on the railway's-online purchasing system.　 Which has been unable to keep pace with the huge demand and also failed to stop scalpers（票贩子） from ending up with many of the hard-to-find tickets.

While insisting that online sales were the fairest way to get tickets for travelers, railway officials told reporters that the public need to be patient.　 Efforts were being made to provide online identity checks that would reduce the ticket scalping problems. While officials had little good news for rail passengers,　 they did manage to bring a few smiles to those traveling by car as the country's extremely expensive highway tolls （通行费）　 will be free of charge for the period of the official holiday.

As you move around your home, take a good look at the things you have. It is likely that your living room will have a television set and a video, and your kitchen a washing machine and a microwave oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat out at least once a week.

Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for. Seeking material success is beginning to trouble large numbers of people around the world. They feel that the long hours work culture to make more money is eating up their lives, leaving them very little time or energy for family or pastimes. Many are turning to other ways of living and downshifting is one of them. Six percent of workers in Britain took the decision to downshift last year.

One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day from their large house in the suburbs, leaving their two children with a nanny. Most evenings Daniel wouldn’t get home until eight or nine o’clock and nearly twice a month he would have to fly to New York for meetings. They both earned a large amount of money but began to feel that life was passing them by.

Nowadays, they run a farm in the mountains of Wales. “I always wanted to have a farm then,” says Daniel, “and we took almost a year to make the decision to downshift. It’s taken some time getting used to, but it’s been worth it. We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it’s made us stronger as a family, and the children are much happier.

Liz, however, is not quite sure. “I used to enjoy my job, even though it was hard work and long hours. I’m not really a country girl, but I suppose I’m gradually getting used to looking after the animals. One thing I do like, however, is being able to see more of my children. My advice for other people wanting to do the same is not to think about it too much, or you might not do it at all.”

1.The passage tells us that ________.

2.When Daniel was a reporter, he ______.

3.Daniel and Liz both agree that the move to the farm ______.

4.The underlined word “downshifting” in the 2^nd paragraph refers to    ______.

I moved from the busy downtown to the countryside around Shanghai when I started elementary school. At first, I thought I was going to hate it, but to my surprise, I found that I preferred the quiet country life over the noisy city life.

The next move was more of a surprise for me. I was having a good time with my friends at school. But all of a sudden, my mom told me that we were going to move to the United States. Can you imagine how I must have felt ?My English wasn’t that good, though I did know the basics.

The day I arrived in the US was a snowy day. For a girl who grew up in Shanghai and hadn’t seen real thick snow on the ground, it was a big thing. Compared with my school in China, there were a lot more creative thinking questions, which I was better at anyway.

Time flew by and it had been almost four years since I moved. Then again, I was told we were going to move to Singapore.

As I’m writing this article, I am still new here and have been going to school for about two and a half months. I found out that the education here is quite special. Different from AP system in the US, the Singapore CIS uses the IB system.

This switch drowned me in constant stress. I was confused about the new curriculum, and I knew it would take me a long time to adapt. But what I’ve gotten out of my experience over three countries is that no matter where you are studying, you are always learning. And a piece of advice to people who are going to move around the globe: It’s always best to just roll with it.

When I began planning to move to Auckland to study, my mother was a little worried about the uncertainty of living in a place that was so different from India, where we lived. She worried particularly about the lack of jobs and cultural differences and the chance that I would face racism(种族主义).

Despite these concerns, I came to New Zealand in July 2009.I found the place and the people very nice and supportive. Soon after I arrived, I realized the importance of getting a job to supply my living expenses.

Determined to do this on my own, I spent a whole day going from door to door for a job. However, I received little or no response.

One afternoon, I walked into a building to ask if there were any job opportunities. The people there were very surprised and advised me not to continue my job search in that manner. As I was about to leave, a clerk in the building, who had been listening to what others had said, approached me and asked me to wait outside. Fifteen minutes later, he returned, and asked me what my plans were and encouraged me to stay confident. Then he offered to take me to his friend’s company, Royal Oak, to search for a job. The following day, I received a call from a store in Royal Oak offering me a job.
