Chris is not a traditional explorer— he usually {#blank#}1{#/blank#} (work) in an office for a large organization. However, Chris' job can be just {#blank#}2{#/blank#} exciting and dangerous as being an explorer.

    Chris is a doctor from France and he works for MSF,{#blank#}3{#/blank#} is also known as Doctors Without Borders. MSF sends its doctors all over the world {#blank#}4{#/blank#}(help) people after a war or a disaster. The organization received the Nobel Peace Prize in 1999.

    At the moment, there are over 27,000 trained doctors taking part in MSF projects and tasks. This year, more than 2300 international doctors will join {#blank#}5{#/blank#} (they) to provide medical help around the world. All kinds of doctors can volunteer for MSF. They need to be {#blank#}6{#/blank#} (prepare) to go almost anywhere and, of course, they should expect difficult conditions. When MSF accepts a doctor for a task, he has to go for {#blank#}7{#/blank#} least six months.

    When {#blank#}8{#/blank#} (ask) why he left a comfortable life and a good salary to join MSF, Chris said, “The experience I gain is a great help in my career. More {#blank#}9{#/blank#} (important), it is great to know at the end of each task that I have made a real {#blank#}10{#/blank#} (different) to people's lives.”

    Tom is a boy with physical{#blank#}1{#/blank#}（disable）and he can't walk as {#blank#}2{#/blank#} normal boy. In order to offer him more convenience, his mother bought him a robot {#blank#}3{#/blank#} name is Jimmy yesterday. Jimmy accompanies Tom every day after his parents leave for work{#blank#}4{#/blank#}（take）care of him. Tom suffers from a rare disease. He can't stand{#blank#}5{#/blank#}Instead, he has to sit on an armchair all the day. Jimmy show sympathy to Tom and tries his best to make him happy. Some days ago, he took Tom to the park. He tried to protect him from being harmed. He gave Tom encouragement to have a try to walk. So Tom{#blank#}6{#/blank#}But to Jimmy's disappointment, Tom fell on the ground, causing some other boys nearby to make fun{#blank#}7{#/blank#} him. “Don't laugh at the disabled!” Jimmy turned{#blank#}8{#/blank#} warning those boys. They felt sorry and ran away immediately. The next day, Jimmy took Tom to the park once again. This time, Tom was{#blank#}9{#/blank#} to the circumstance and didn't feel clumsy（笨拙的）any longer. He gets back his own confidence{#blank#}10{#/blank#} he is still a disabled boy.

    It seems that Chinese people have always loved to discuss {#blank#}1{#/blank#}differences between northerners and southerners. Now, another difference has drawn wide attention: the way northerners and southerners shop {#blank#}2{#/blank#} food at markets.

    People from southern China normally buy {#blank#}3{#/blank#}they need for just one or two meals at a time. It's normal for them to buy just half a Chinese cabbage, two {#blank#}4{#/blank#}(potato) and 25 grams of beef at a time. {#blank#}5{#/blank#}, a person may be laughed at if they do this in the north. Instead, buying enough vegetables and meat for a week {#blank#}6{#/blank#} (be) normal.

    The different could be because of the different climates. Food can {#blank#}7{#/blank#} (keep) for a long time in the north, as it's {#blank#}8{#/blank#} (usual) cold and dry there. Many northerners have the habit of {#blank#}9{#/blank#} (store) food for a long time. But due to the hot and wet weather in the south, southern Chinese people prefer {#blank#}10{#/blank#}(buy) just enough food for one meal or one day. Otherwise, the food may go bad.

    Maybe these debates about different customs help us to understand each other better.

    The year of 2014 was pretty tough for Stevens. Unfortunate{#blank#}1{#/blank#}(event) happened to him one after another. He lost all his wealth and couldn't pay for his insurance, but there was even {#blank#}2{#/blank#}(bad) news to come. He had skin cancer, {#blank#}3{#/blank#}made him ready to give up.

    {#blank#}4{#/blank#}(lucky), he managed to find a job later and moved into a new home. It was then that Stevens seemed to turn a corner and realized his life was still worth {#blank#}5{#/blank#}(fight) for. He wrote in his blog, "My wife had told me many times she wished she could visit New York one day. She also wished we had had a place{#blank#}6{#/blank#}(exercise) outside and watched our daughters playing." He decided to put his plan into {#blank#}7{#/blank#}(act) — building a garden. To make a surprise for his wife, Stevens sent her off for a trip to New York City.

    Then, he went crazy building the garden. After ten days, all the work {#blank#}8{#/blank#} (pay) off. It made a big difference to Stevens' life. He wrote, "The kids love  {#blank#}9{#/blank#} (they) new space. And I feel strangely{#blank#}10{#/blank#} (satisfy) to build this, which inspires me to keep going."

Living in a city can be stressful. But people in Bogota, Colombia have found a place to help ease stress and get a{#blank#}1{#/blank#}(peace) break from busy life. The place is a {#blank#}2{#/blank#}(protect) park for hummingbirds(蜂鸟).

The park is at the top of Montserrat Hill. The area{#blank#}3{#/blank#} (contain) a forest which has turned into a quiet place for both people and birds. As the hummingbirds fly from flower to flower, some people take pictures with cameras or phones.

"Sometimes it doesn't seem real because we are close to{#blank#}4{#/blank#} city with the population of 8 million,{#blank#}5{#/blank#} create noise every day," said Camino Carter, a caretaker in the park. His job is{#blank#}6{#/blank#}(mix) water and sugar that is put in bird feeders.

{#blank#}7{#/blank#}(visitor) to the park can see between 25 to 35 different species of birds. But ten years ago, the hill was {#blank#}8{#/blank#} (complete) destroyed, and no trees {#blank#}9{#/blank#}(leave) on it.

Luckily, measures were taken by the government. Workers began to replant local trees and flowers to bring the forest back{#blank#}10{#/blank#} life.

Presently, there are 115 species of birds, including 18 kinds of hummingbirds in the park.
