Zhang Jianxing has been walking through the ancient forests of the Shennongjia National Nature Reserve for over two decades to find the wild man. He will not give up until he {#blank#}1{#/blank#} (come) face-to-face with the creature. He began living in the mountain in 1994. after becoming{#blank#}2{#/blank#}(fascinate) by the wild man. Armed with a camera, he {#blank#}3{#/blank#}(constant) looks for clues of the creature's whereabouts, living off the land and {#blank#}4{#/blank#}(sleep) in abandoned homes and empty eaves. To him, the wild man is a branch of science, {#blank#}5{#/blank#} that he has been studying for a very long time. So far, he has collected enough evidence of the wild man's {#blank#}6{#/blank#} (exist)—more than 100 hair samples and 3,000 photos of large footprints (脚印).He even came close to seeing it for himself no less than nineteen {#blank#}7{#/blank#} (time). However, most scientists regard it as nothing more than a legend {#blank#}8{#/blank#} there is a lack of concrete evidence. But Zhang Jianxing {#blank#}9{#/blank#} (convince) that he will one day find the wild man himself and prove the scientists wrong. To him it's just {#blank#}10{#/blank#} matter of time.

    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.
