Today so many people are talking about AIDS, for which, {#blank#}1{#/blank#} (fortunate)，there is no cure now. When we talk about its influence on our society, this disease is {#blank#}2{#/blank#} most severe public health problem of all that we are facing in the 21^st century. It is spreading at a(n) {#blank#}3{#/blank#} (surprise) speed, especially in Africa.

    The UN AIDS organizations have come to the {#blank#}4{#/blank#} (conclude) that in the past 20 years, 20 million people have died of AIDS. And this figure will be three times bigger in the next two decades {#blank#}5{#/blank#} measures are taken in poor countries. Only if people change their basic behavior in time, can AIDS {#blank#}6{#/blank#} (stop) from spreading. For example, in San Francisco, the rate fell greatly when a serious program was carried out. People were {#blank#}7{#/blank#} (please) to change their behavior when they realized how serious a risk they were taking.

    Experts think in order to get the message across to those {#blank#}8{#/blank#} don't realize the seriousness of AIDS, a well {#blank#}9{#/blank#} (design) educational campaign is the only thing at the moment that can help. It would be criminal not to put it into practice. So everyone has a share of responsibility in the fight {#blank#}10{#/blank#}AIDS.

    Many English language learners believe that the {#blank#}1{#/blank#} (great) difficulty with listening comprehension (理解) is that the listener cannot control how quickly a speaker speaks. They feel that what the speaker says disappears {#blank#}2{#/blank#} they can follow. This frequently means that students {#blank#}3{#/blank#} are learning to listen cannot keep up. They are so busy working out the meaning{#blank#}4{#/blank#} one part of what they hear that they miss the next part. Or they {#blank#}5{#/blank#}(simple) ignore a whole section because they fail to catch it quickly enough. Another difficulty is that the listener is not always in a position to get the speaker to repeat what has been said. And, of course, repeats cannot{#blank#}6{#/blank#} (ask) for when listening to the radio or watching TV.

    Besides,{#blank#}7{#/blank#} (choose) of vocabulary is in the hands of the speaker, not the listener. Very often, for people listening to a foreign language, an unknown word can be like a suddenly {#blank#}8{#/blank#} (drop) stone making them stop and think about the meaning of the word,{#blank#}9{#/blank#} (cause) them to miss the next part of the speech. In listening, it really is a case of “He who{#blank#}10{#/blank#} (stop) to work out the meaning is lost.”

    Tim Cook，the CEO of Apple，showed off their newest device，the Apple Watch．Mr．Cook said it was the most personal device Apple{#blank#}1{#/blank#}(create)．

    The Apple Watch is a very small computer a person wears on his or her wrist．It can do many of the same things{#blank#}2{#/blank#}an iPhone．The apps are customized(定制) for the watch．It is different than just seeing{#blank#}3{#/blank#}is on your phone．

    Like a phone，you will be able to receive{#blank#}4{#/blank#}(call)on your wrist．Mr.Cook smiled while{#blank#}5{#/blank#}(describe) this. “I've been wanting to do this since I was five years old，”he said. “The day is{#blank#}6{#/blank#}(final) here．”

    The watches arrived in stores{#blank#}7{#/blank#}late April．They are sold at different prices，beginning at ＄349．Mr．Cook said the high-end model，the one{#blank#}8{#/blank#}(make) of 18-karat gold，is thousands of dollars.

    One problem with Apple Watch is that you need an iPhone on your body，or nearby{#blank#}9{#/blank#}(get) this watch to function fully．Like a phone，it also needs to be charged each night. It remains to be seen whether people really want to carry both a smart phone{#blank#}10{#/blank#}a smart watch.

    Martin Strel swims with a knife {#blank#}1{#/blank#} (fasten) to his right leg—in case he meets sharks and other {#blank#}2{#/blank#}  (dead) sea life in the world's wildest waters. {#blank#}3{#/blank#} 61-year-old marathon swimmer has announced the {#blank#}4{#/blank#} (tough) challenge of his life: a 10,000-mile-around-the-world journey on water {#blank#}5{#/blank#} (draw) public attention to the increasing water {#blank#}6{#/blank#} (pollute). He aims to circle the globe in about 450 days, passing through oceans, rivers,{#blank#}7{#/blank#} (canal) and other bodies of water in more than 100 countries. He will swim about 5 to 12 hours each day, depending on the weather. A boat will go {#blank#}8{#/blank#} him and offer emergency support and space for small breaks.

    Since 2000, Strel {#blank#}9{#/blank#} (swim) the entire length of five rivers in China, America, etc. Strel will not be alone in the water. He says he welcomes {#blank#}10{#/blank#} is interested in joining him for parts of the route.

    China is known as the Kingdom of Bamboo. More than 400 species of bamboo, one third of all known species in the world, grow in China. China {#blank#}1{#/blank#}(lead) the world in the amount of area planted with bamboo, the number of bamboo trees and the amount of bamboo wood{#blank#}2{#/blank#} (produce) every year.

    The oldest bamboo{#blank#}3{#/blank#}(article) in China were unearthed from the remains of a primitive society that existed some 7,000 years ago in{#blank#}4{#/blank#} is now Hemudu, Yuyao County, Zhejiang Province. As early as the Shang Dynasty, Chinese people used the bamboo for making weapons ,，such as bows and arrows. Before paper{#blank#}5{#/blank#}(invent), strips of bamboo were the most important writing medium, more widely used than silk, {#blank#}6{#/blank#} they were cheaper, resistant to corrosion (腐蚀)，and more abundant. Bamboo has thus played an important part in the spread and development of traditional Chinese culture.

    Bamboo was{#blank#}7{#/blank#}(close) connected with the daily lives of people in ancient China. Su Dongpo, a literary giant of the Song Dynasty, said that people could not live{#blank#}8{#/blank#}bamboo, and people of the time used bamboo {#blank#}9{#/blank#}(make) paper, hats, shoes and so on. At that time, as today, bamboo shoots were eaten as a popular dish because of {#blank#}10{#/blank#} (they) crispness and fresh, sweet taste. Bamboo shoots also contain vitamins, sugar, fat, and protein.
