Not all memories are sweet. Some people spend all their lives trying to forget bad experiences.

   Now American researchers think they are close to developing a pill, {#blank#}1{#/blank#} will help people forget bad memories. The pill is {#blank#}2{#/blank#}(design)to be taken immediately after a frightening experience. They hope it might reduce, or {#blank#}3{#/blank#}(possible) erase (抹去) the effect of painful memories.

   In November, experts tested a drug on people in the U.S. and France. The drug stops the body from {#blank#}4{#/blank#}(release) chemicals that fix memories in the brain. So far, the research {#blank#}5{#/blank#}(suggest) that only the emotional effects of memories may be reduced, not that memories are wiped out. They are not sure to the degree people's memories are affected.

   The research has caused a great deal of {#blank#}6{#/blank#}(argue). Some think it is {#blank#}7{#/blank#}bad idea, while others support it. Supporters say it could lead to pills which prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer {#blank#}8{#/blank#}terrible memories. {#blank#}9{#/blank#}, those who are against the research say that maybe the pills can change people's memories and changing memories is very {#blank#}10{#/blank#}(danger) because memories give us our identity.

    Several countries in Asia celebrate the Lunar New Year in their own way. But dragon and lion dances in Chinatowns all over the world have helped to make China's New Year the most famous. These days growing {#blank#}1{#/blank#}(number) of people who are not of Chinese origin are joining in. In Tokyo window cleaners dress up like the animals of the Chinese Shengxiao. America, Canada and New Zealand have published memorial stamps for the year of the rooster. Last year New York City made the Lunar New Year {#blank#}2{#/blank#}school holiday for the first time.

    The spread of the Spring Festival is {#blank#}3{#/blank#}(part) due to recent immigration from China: 9.5 million Chinese people {#blank#}4{#/blank#}(move) abroad since 1978, many of {#blank#}5{#/blank#}are far richer than earlier waves of immigrants.

    Aware {#blank#}6{#/blank#}China's growing economic and political influence, foreign leaders have noticed the occasion. Britain's prime minister, Theresa May, has given a video address, a tradition {#blank#}7{#/blank#}(start) in 2014 by her predecessor (前任) . This year's World Economic Forum in Davos was held a week earlier than usual {#blank#}8{#/blank#}(avoid) conflicting with China's New Year.

    China hopes the festival will promote  {#blank#}9{#/blank#}(it) cultural “soft power” abroad. It may give the Chinese people {#blank#}10{#/blank#}(satisfy) to see foreigners enjoy such festivities.

    If this 13-year-old American boy succeeds in his effort {#blank#}1{#/blank#} (climb) Mount Everest, he has modest ambitions — pick a small piece of rock from the top of the world as a memento (纪念品) and wear it in a necklace.

    "I will not sell it or give it to anyone. It is something for {#blank#}2{#/blank#} (me) to say 'this is a rock from the summit'," Jordan Romero from California, told reporters in Kathmandu. He left {#blank#}3{#/blank#} the mountain on Sunday.

    If he {#blank#}4{#/blank#} (succeed), Romero will become {#blank#}5{#/blank#} youngest climber to scale the 8,850 meters Everest summit. {#blank#}6{#/blank#} (current) a 16-year-old Nepali boy, Temba Tsheri Sherpa, holds the record of being the world's youngest climber of Mount Everest. But Romero said he was not after {#blank#}7{#/blank#} (set) climbing records.

    Romero said Mount Qomolangma was part of his goal to climb the highest mountains on all seven {#blank#}8{#/blank#} (continent).

    "It is just a goal," he {#blank#}9{#/blank#} (say) confidently. "If I don't succeed I am okay. I will try again."

    Romero has already climbed Mount Kilimanjaro in Africa and Mount McKinley in Alaska among others.

    "I know it requires a lot of {#blank#}10{#/blank#} (patient). I will remain patient. I want to stay safe and make right choice," Romero said.
