During rush hours, you never know when a bus or a taxi might come. Walking might be too tiring. If it's about two or three miles away, which kind of transportation will you choose?{#blank#}1{#/blank#}

    Bike shares are a growing convenience in many cities around the world.{#blank#}2{#/blank#} Riders usually have to pick up a bike at a self—serve station and return it at another station later. However, a Chinese bike—sharing company called Ofo, is bringing this idea to a new level.

    Like any other bike—sharing service, Ofo users can get a bike at any time.{#blank#}3{#/blank#} Instead, they can pick one up wherever and whenever they please. To get a bicycle, riders with the app are able to find the nearest one.{#blank#}4{#/blank#}After parking the bike, all they have to do is to lock it.

    This Chinese company already has its bicycle throughout China, the United States and Singapore.{#blank#}5{#/blank#} “We want to reach more cities, connect more bikes and serve more people”, said Ofo founder Dai Wei.

A. Thousands of bike sharing programs have been set up by the governments.

B. When a rider is done with the bike, returning is just as easy.

C. This month, 500 Ofo bicycles will be set up in Cambridge, England.

D. For short journeys, riding a bike could be the best solution.

E. The big difference is that they don't need to find a self—serve station.

    Some people seem to have unusual memories. Zheng Aiqiang, a "memory athlete" on TV show Super Brain, can remember 2,660 numbers in just one hour!

    You would think people like him must have special brains. But according to a recent study by researchers from America and Holland, the brain structure (结构) of ordinary people and 23 of the world's leading memory athletes shows no difference.

    Good memories can be trained. New research in the magazine Neuron suggests that a person will get a super memory with just six weeks of hard training.

    Researchers found that a technique (技巧) called loci, invented by the ancient Greeks, can greatly help improve memory.

    By using loci, you are using your imagination to improve the brain's memory networks. You can link (关联) something you need to remember with a place that you know very well. For example, to remember a list of numbers, imagine yourself walking through your house. Each thing is linked to a number. For example, zero could be the handle on the door and five could be the painting on the wall.

    In one study, some ordinary people were given 20 minutes to remember 72 nouns. At the beginning, they could only remember 26 words, but when they were taught loci, they could remember 62 words.

    "Not everyone can become a memory winner. But everyone using the technique can improve his memory greatly," said Boris Konrad, one of the researchers in the study.

    Rishi was a 10-year-old boy. Just like any other boy of his age, he hardly did the housework his parents told him to do, and usually he would completely ignore(忽视) them.

    It was a 5-day holiday. He spent a good time with his mother. She took him for outings. They went to the beach and parks and had delicious meals. She cooked his favourite foods and played with him. Three days was left and Rishi's mother wanted him to clean the house with her. To her surprise, he agreed and did everything well.

    After Rishi finished the work his mother asked him to do, he gave her a piece of paper written by him. She was greatly surprised to see what he wrote.

She didn't say a word and wrote on a piece of paper and gave it to her son. She wrote:

    The boy was in tears and rushed to his mum and gave her a big hug. He told his mother, "Mum, I love you. I'm sorry for everything." Rishi's mother kissed him on his forehead.

    For most people, summer holidays mean sun, sea and sand, {#blank#}1{#/blank#}. She had a holiday full of ice and snow. She and her family travelled across Greenland! Starting just above the Arctic Circle (北极圈), Sarah's family used dogsleds with kites to cross the world's biggest island.

    Sarah says {#blank#}2{#/blank#}. "There is only snow, ice, and more snow. " The family travelled 15 miles a day for 22 days, moving faster when strong winds pushed along their kites.

    Then the weather became a bit hot for the dogs to pull sleds during the day, {#blank#}3{#/blank#}. The Landrys lived in tents, ate dried food, and took baths with heated water. When they weren't travelling, they played with kites and made snowmen. Using their mobile phones, the family could send and get emails even from Greenland's ice cap! The road to the top was icy and dangerous.

    {#blank#}4{#/blank#}. "Icebergs (冰山) were so bright, just like the rising sun." said Sarah. Now she and her family have returned home, {#blank#}5{#/blank#}. Next holiday, they are going to the South Pole.
