    I'm a rock-climbing guide . Climbing the rocks and mountains in Yosemite National Park {#blank#}1{#/blank#} (be) my life's passion since I was 13 . More than ten years ago I started seeing a lot of waste , {#blank#}2{#/blank#} toilet paper , beer cans , and empty boxes , around the area . {#blank#}3{#/blank#} was beyond me why visitors started respecting the place less and treated such a beautiful home-like place this way . I {#blank#}4{#/blank#} (try) picking up trash myself , but I would spend an hour or two on the job , only   {#blank#}5{#/blank#} (find) the area trashed all over again weeks {#blank#}6{#/blank#}. I decided something had to change . I set a date for a cleanup together with some other climbers . {#blank#}7{#/blank#} (expect) , more than 300 people showed up . We collected about 6,000 pounds of trash over three days . It was  {#blank#}8{#/blank#} (amaze) how much we were able to accomplish—the park looked clean ! I often hear people complain about their surroundings . I want to say the only way to change things is by doing rather than   {#blank#}9{#/blank#} (complain) . We need to teach by example .

    Dogs were first raised at home at least 150 centuries ago. Since then, the dog {#blank#}1{#/blank#} (be) humans' best friend. Now, they have another job—to assist doctors to diagnose（诊断）cancer.

    After a long-standing research of smell, a Finnish professor has said that certain {#blank#}2{#/blank#} (type) of cancer are able to be detected by their smell, making it possible to train cancer-sniffing dogs {#blank#}3{#/blank#} (help) diagnose the disease.

    A professor, Jouko Vepsalainen from the University of Eastern Finland in Kuopio, has focused {#blank#}4{#/blank#} nitrogen compounds（氮化合物）. The compounds increase {#blank#}5{#/blank#} (great) when cancer cells grow in an uncontrollable way, {#blank#}6{#/blank#} (allow) them to be detected, the Finnish newspaper Karjalainen reported. That's where the dog, man's best friend, may step in with their keen sense of smell.

    According to the news agency, researchers in Finland have tried to train dogs to do the job, but {#blank#}7{#/blank#} will take a dog months, even years, to tell the {#blank#}8{#/blank#} (different) between sick and healthy people. “Anyone {#blank#}9{#/blank#} knows how difficult early cancer detection is {#blank#}10{#/blank#} (understand) what an opportunity this is,” associate professor Anna Hielm-Bjorkman of the University of Helsinki told the Finnish media.

    Over the past few years, square dance {#blank#}1{#/blank#} (become) a more and more popular exercise, especially among senior citizens. They often dance in the open areas in community. However, many {#blank#}2{#/blank#} (resident) who live around are annoyed by the loud music. For example, students {#blank#}3{#/blank#} (prepare) for important exams are {#blank#}4{#/blank#} (deep) affected.

    People may have different opinions on this issue. Some people think {#blank#}5{#/blank#} is necessary for senior citizens to give up the hobby for the good of most people, {#blank#}6{#/blank#} others argue that senior citizens have the right {#blank#}7{#/blank#}（do）something they like in public places. They are both right to some extent. {#blank#}8{#/blank#} my opinion, the authorities, instead of forcing senior citizens to stop dancing, should do something to meet everybody's requirements. For example, they can supply some buses which can transport senior citizens to a place {#blank#}9{#/blank#}there are few apartments around. Besides, local communities can also organize leisure activities that little noise {#blank#}10{#/blank#} (create).

    In short, there are always some good ideas that can meet the needs of people. After all, everybody has the right to live a happy and fulfilled life.

    Being overweight can cause depression even when no other health problems exist, according to a study released Tuesday by the University of Exeter.

    A team {#blank#}1{#/blank#} (lead) by researchers from the University of Exeter analyzed UK Biobank data (基因数据库) from more {#blank#}2{#/blank#} 48,000 people with depression and {#blank#}3{#/blank#} (compare) them to another group of more than 290,000 people.

    While {#blank#}4{#/blank#} has long been known that depression is more common in obesity, the team concluded {#blank#}5{#/blank#} higher body mass index(体重指数) can cause depression in itself, even in the obese {#blank#}6{#/blank#} other health problems.

    Our genetic analysis concludes that the psychological impact of being obese is likely {#blank#}7{#/blank#}(cause) depression. This is important to help target efforts to reduce depression, {#blank#}8{#/blank#} makes it much harder for people to adopt {#blank#}9{#/blank#} (health) lifestyle habits, said Dr Jess Tyrrell. The team tested their results in many people and they reached {#blank#}10{#/blank#} same conclusion, verifying their results.

    The study has been published in the International Journal of Epidemiology.

    With a timid voice, the little boy greeted his father as he returned from work, "Daddy, how much do you make an hour?"

    Greatly {#blank#}1{#/blank#} (surprise), the father said, "Look, son, not even your mother knows that. Don't bother me now, I'm tired."

    "But Daddy, just tell me please! How much do you make an hour," the boy insisted.

    The father, {#blank#}2{#/blank#} (final) giving up, replied, "Twenty dollars per hour."

    "Okay, Daddy? Could you loan me ten dollars?" the boy asked.

    Showing his restlessness, the father yelled, "So that was the reason {#blank#}3{#/blank#} you asked how much I earn, right? Go to sleep and don't bother me any longer!"

    It was already dark and the father was thinking about what he {#blank#}4{#/blank#} (say) and was feeling guilty. Maybe he thought his son wanted to buy something. Finally, trying to ease {#blank#}5{#/blank#} (he) mind, the father went to his son's room.

    "Are you {#blank#}6{#/blank#} (sleep), son?" asked the father.

    "No, Daddy. Why?" replied the boy.

    "Here's the money you asked for {#blank#}7{#/blank#} (early)," the father said.

    "Thanks, Daddy!" replied the son happily, putting his hand under his pillow and removing some money. "Now I have enough! Now I have twenty dollars!" the boy said to his father, who was gazing at his son, confused {#blank#}8{#/blank#} what his son had just said.

    "Daddy, could you sell me one hour of your time?"

    Time is {#blank#}9{#/blank#} precious to spend it all on work! Appreciate your loved {#blank#}10{#/blank#} (one) and don't take them for granted.

Chinese was formally announced an official language of the United Nations World Tourism Organization on January 25.

That means the organization will use the Chinese language, {#blank#}1{#/blank#} will enhance China's soft power in global tourism and, by extension, the cultural domain. It will help China's tourism growth, encouraging other countries {#blank#}2{#/blank#}(adopt) its policies. Tourist places in Chi too will get more exposure. The number of people learning Chinese will {#blank#}3{#/blank#} (definite) grow.

There {#blank#}4{#/blank#}(be) two main reasons for that. First. Chinese cultural and tourism authorities have been promoting Chinese culture for long. As far back as in 2006. Spring Festival was listed as a {#blank#}5{#/blank#} (nation)cultural heritage(文化遗产)and given special {#blank#}6{#/blank#}(protect)and promoted. Now, there are many influential festival {#blank#}7{#/blank#}(list) in the world and almost all of them list the Chinese New Year. or Spring Festival: many even list {#blank#}8{#/blank#} at the top. Second. the year-on-year growth in the number of Chinese tourists before 2020 too has played a part in promoting the Chinese language and culture. Globally. Chinese faces have become common at scenic spots. That has a lot to do {#blank#}9{#/blank#}China's improving economy and the constantly rising per capital income(人均收入).

With China's growing comprehensive capabilities, it {#blank#}10{#/blank#}(hope) that its influence in other soft power domains will also grow.
