The story happened in ancient times. A king was so clever that he thought of a good way to test{#blank#}1{#/blank#}his men were reliable.

    One day, he had a huge rock{#blank#}2{#/blank#}(place) on a roadway at night. Then he hid {#blank#}3{#/blank#} (him) nearby and watched carefully to see if anyone would remove the big rock. Some{#blank#}4{#/blank#}(wealth) businessmen and high officials came by, but they simply walked around it. Many of them even loudly blamed the king for not keeping the roads clear, but none of them would bother{#blank#}5{#/blank#}(get) the big stone out of the way.

    Then a villager came along carrying a load of vegetables. On {#blank#}6{#/blank#}(approach) the big rock, he stopped and laid down his burden, trying hard to move the stone to the side of the road. After much pushing, he{#blank#}7{#/blank#}(final) succeeded. As the villager picked up his load of vegetables, he noticed a purse lying in the road where the rock{#blank#}8{#/blank#}(be). The purse contained many gold coins and a note from the king, saying that the gold was for the person{#blank#}9{#/blank#} removed the huge rock from the road.

    The villager learned a valuable lesson that many others would never understand: Every obstacle presents{#blank#}10{#/blank#} opportunity to improve one's condition.

    There was a man who had four sons. He wanted his sons to learn not to judge things too{#blank#}1{#/blank#}(quick). So he sent them each to go and look at a pear tree that was far{#blank#}2{#/blank#}

    The first son went in the winter, the second in the spring, the{#blank#}3{#/blank#}in the summer, and the youngest son went in the autumn. When they had all{#blank#}4{#/blank#}(go) and came back, he called them together to describe what they{#blank#}5{#/blank#}(see)．

The first son said that the tree was ugly. The second son said no—it was covered with green buds and full of promise.

    The third son{#blank#}6{#/blank#}(agree). He said it was full of flowers that looked very beautiful.

    The last son said it was full of fruit.

    The man then explained to his sons that they were all wrong，{#blank#}7{#/blank#}they had each seen just one season in the tree's life.

    He told them that you cannot judge what a tree is, or how a person is，{#blank#}8{#/blank#}only one season. The{#blank#}9{#/blank#}(please), joy and love come from that life can only be measured at the end.

    If you give up when it's winter, you{#blank#}10{#/blank#}(miss)the promise of your spring, the beauty of your summer and the fruit of your fall.

    As kids reach adolescence, they often face increasing workloads and responsibilities but school still starts early. As a result, it {#blank#}1{#/blank#} (report) that 80 to 90 percent of teens don't get enough sleep. This sleep {#blank#}2{#/blank#} (lose) causes kids to suffer mentally and physically. But too much sleep also has its problems. According to Andrew Fuligni, a sleep doctor in a famous hospital,{#blank#}3{#/blank#} studies the mental health of adolescents, sleeping less than eight hours {#blank#}4{#/blank#}more than ten can make teenagers feel worse the next day.

    {#blank#}5{#/blank#} (help) teens get enough sleep, some schools have already made school start later. They have found that the later times let kids sleep more. They also have seen{#blank#}6{#/blank#} (high) test scores and better graduation rates. However, this isn't enough. Meanwhile, teenagers have to help {#blank#}7{#/blank#} (they). Fuligni suggests teens sleep{#blank#}8{#/blank#}10 hours each night for a week or two. This will help them figure out how much sleep they need. However, sleeping more on weekends {#blank#}9{#/blank#}(be) not a good idea to compensate for missing sleep during the week. Fuligni warns that getting different {#blank#}10{#/blank#}(amount)of sleep each night can be bad for mental health.

    The Silk Road is in fact {#blank#}1{#/blank#} relatively recent term. These ancient roads had no particular name until in the mid-nineteenth century; Baron Ferdinand von Richth often named the trade and communication network the Silk Road. Since then the term {#blank#}2{#/blank#}（accept）globally.

    In the nineteenth century, a new type of travelers stepped onto the Silk Road: archaeologists and geographers, enthusiastic explorers who were eager {#blank#}3{#/blank#}（look）for adventure.

    Researchers who came from many countries traveled through the Taklamakan Desert, {#blank#}4{#/blank#} is now in Xinjiang, to explore ancient sites along the Silk Road, {#blank#}5{#/blank#}（lead）to many discoveries and studies, and most of all, a renewed interest {#blank#}6{#/blank#}the history of these routes.

    Today, many historic {#blank#}7{#/blank#}（build） and monuments still stand, marking the passage of the Silk Road through hotels, ports and cities. What's more, the long - standing legacy （遗产） of this {#blank#}8{#/blank#} （remark）network is reflected in a large number of cultures, languages, customs and religions that have developed for many years along these routes. The passage of merchants and travelers of many different nationalities resulted not only in commercial exchange {#blank#}9{#/blank#} in a widespread and continual process of cultural interaction. {#blank#}10{#/blank#}（obvious）, it has become a driving force in the formation（形成）of diverse societies.

    Does the name of the college you attend really matter? Research on the question {#blank#}1{#/blank#} (suggest) that, for most students, it doesn't. What students do at college seems to matter much more than {#blank#}2{#/blank#} they go. The students benefitting most from college are those {#blank#}3{#/blank#} are totally engaged (参与) in academic life. taking full advantage of the college's chances and resources (资源). Students should have a proper attitude towards college before thinking about which college to attend, and it's never too early to make necessary preparations for a healthy and {#blank#}4{#/blank#} (meaning) college experience.
