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.

    A recent study suggests that students who bring water into exams may improve their grades by 10 percent．

    Scientists then {#blank#}1{#/blank#} (比较) their exam results with their normal schoolwork grades．They found that all those {#blank#}2{#/blank#} had brought drinks with them got better grades．

    Scientists also considered the students 'schoolwork and {#blank#}3{#/blank#} (预计)their grades．This was to make sure that the reason was not simply that smarter students were more {#blank#}4{#/blank#} (有可能)to bring drinks with them．

    {#blank#}5{#/blank#} is unclear why drinking water improves exam results．But scientists say having enough water in our b{#blank#}6{#/blank#} and not feeling thirsty could have a helpful effect {#blank#}7{#/blank#} our brains．Drinking water may also cut d{#blank#}8{#/blank#} on anxiety ,which affects exam performances．

    So next time， w{#blank#}9{#/blank#} you are going to have a big exam，try bringing a bottle of water with you．Who knows—it may help you p{#blank#}10{#/blank#} the exam!

    How would you feel if you woke up and found your entire computer's contents — including your photos, your recent documents — no longer {#blank#}1{#/blank#}(access)? What if you found out that they had {#blank#}2{#/blank#}(wipe) from your computer, leaving you with nothing but heartache?

    Guess what? It happens to people every single day. Every day, people across the country head into their local Apple store in {#blank#}3{#/blank#}(tear), broken computer in hand, praying as they wait in line that {#blank#}4{#/blank#}expensive repair might, just might, recover {#blank#}5{#/blank#}priceless, irreplaceable files. A few get lucky. But for the rest, there's nothing anyone can do {#blank#}6{#/blank#}(help).

    Hasn't happened to you? If your computer{#blank#}7{#/blank#}(remain) unprotected, it will, and it's only a matter a time. But thanks to recent breakthroughs in computer backup technology, you now have a number of options to prepare, and if you're smart, when your computer{#blank#}8{#/blank#}(crash), you shouldn't have any problem {#blank#}9{#/blank#}(get) 100% of your files back that same day. I'm not talking about an external hard drive. I'm talking about an online backup {#blank#}10{#/blank#}(solve) that runs quietly in the background on your computer. If you have one installed, when your computer crashes, you'll be just one click away from bringing your files back to life.

    Choice of seating in the lecture hall can affect a college student's performance, a study suggests.

    Lectures are a main part of higher education, and {#blank#}1{#/blank#}(understand) how students interact and learn within the lecture theatre environment is central to successful learning. Researchers from Sheffield Hallam University in the UK examined {#blank#}2{#/blank#} (student) reasons for choosing particular seats in a lecture hall, and investigated how seating positions are related {#blank#}3{#/blank#} students' performance.

    "Interaction is a key part of learning and knowing who the students are interacting with can be {#blank#}4{#/blank#} great benefit when designing activities," said David P Smith of Sheffield Hallam University.

    Many students {#blank#}5{#/blank#} (prefer) being able to sit with their friends, {#blank#}6{#/blank#} others were more concerned with either attracting or avoiding the lecturer's attention. Some students chose seats {#blank#}7{#/blank#} allowed them to see and hear clearly. But others {#blank#}8{#/blank#} (easy) picked seats that made them feel less depressed, they said.

    Friendship groups who sat together tended {#blank#}9{#/blank#} (achieve) similar grades, and students who sat alone at the edges were likely to do worse than average.

    Lecturers may be able to use these findings to offer assistance to {#blank#}10{#/blank#} (anxiety) students，and to support the learning of all students by encouraging interactions between the different groups.

Tu Youyou, a {#blank#}1{#/blank#}(commit) and patient scientist, was born in China and graduated from Peking University Medical School in 1955. After graduation, she worked at the China Academy of Traditional Chinese Medicine in Beijing. In 1967, she {#blank#}2{#/blank#} (choose) by the government to join a team of scientists with the aim of discovering a new treatment {#blank#}3{#/blank#} malaria. Her team examined over 2,000 old medical texts, and evaluated 280,000 plants for their medical {#blank#}4{#/blank#}(property). From their research, they discovered and tested 380 distinct ancient Chinese medical treatments that showed promise in the fight against malaria.

After a lot of failures, in 1971, Tu Youyou and her team members succeeded by using a lower temperature {#blank#}5{#/blank#}(draw) out the extract. They even insisted on testing the medicine on {#blank#}6{#/blank#}(they) to make sure that it was safe. Later, the medicine was tested on malaria patients，most of whom recovered. The medicine,{#blank#}7{#/blank#}was called artemisinin, soon became a standard treatment for malaria.

According to Tu Youyou, the discovery of artemisinin was a team effort. Upon {#blank#}8{#/blank#}(hear) that she had been awarded {#blank#}9{#/blank#}Nobel Prize, she said the honour belongs to the team behind her and all the people of her country. The success{#blank#}10{#/blank#}(prove) the great value of traditional Chinese medicine.
