This passage mainly tells us the {#blank#}1{#/blank#}(valuable) of a person. A collage student in this passage {#blank#}2{#/blank#} (choose)the wrong major and became more and more frustrated. He thought he couldn't be successful and achieve {#blank#}3{#/blank#}dream. {#blank#}4{#/blank#}, he only liked to listen to Yang' s class and never  {#blank#}5{#/blank#}(absence). He put a note and showed his value to Yang. One day, Yang told him the {#blank#}6{#/blank#}(different) between different potatoes. So this student understood the life and became successful.

    From this passage, I think, in our lives, we shouldn't move back when we have trouble with our study or work. {#blank#}7{#/blank#} (contrary), we must try hard to make our lives better and be {#blank#}8{#/blank#}(value) one in these common people. If we do, like this, we will show our value by ourselves and be found by top people. So we may change our destiny and become {#blank#}9{#/blank#}(success)

    A recent study suggested that taking a bottle of water into the exam hall could help students improve their grades.

    According to the study those who brought drinks,{#blank#}1{#/blank#}(especial) water, with them when sitting their exams performed up to 10 percent better than those who did not.

    Comparing their exam results with their normal schoolwork grades, scientists then found that all those who {#blank#}2{#/blank#}(bring) drinks with them got better grades {#blank#}3{#/blank#} between 2 and 10 percent.

    It is unclear {#blank#}4{#/blank#} drinking water improves exam results. But scientists say having enough water in our bodies and not feeling thirsty could have a {#blank#}5{#/blank#}（help）effect on our brains. Drinking water may also cut {#blank#}6{#/blank#}on anxiety,{#blank#}7{#/blank#} has a bad effect on exam performances.

    Whatever the explanation, it is obvious that students should try hard to keep enough water in their bodies during exams. So next time,{#blank#}8{#/blank#} you are going to have a big exam, try {#blank#}9{#/blank#} (bring) a bottle of water with you. Who knows — it {#blank#}10{#/blank#} help you pass the exam!

    Once upon a time a very strong woodcutter asked for a job in a timber merchant(木材商), and he got it. The pay was {#blank#}1{#/blank#}(real) good and so were the work conditions.  {#blank#}2{#/blank#} that reason, the woodcutter was determined to do {#blank#}3{#/blank#} best. His boss gave him an axe and showed him the area, {#blank#}4{#/blank#} he was supposed to work. The first day, the woodcutter {#blank#}5{#/blank#} (bring) 18 trees. "Congratulations," the boss said. "Go on that way". Very {#blank#}6{#/blank#}(motivate) by the boss's words, the woodcutter tried harder the next day, {#blank#}7{#/blank#} he could only bring 15 trees. The third day he tried even harder. But he could only bring 10 trees. Day after day he was bringing less and less trees. "I must be losing my {#blank#}8{#/blank#}(strong), " the woodcutter thought. He went to the boss and apologized, {#blank#}9{#/blank#}(say) that he could not understand what was going on. "When was the last time you sharpened your axe? " the boss asked. "Sharpen? I had no time to sharpen my axe. I have been very busy {#blank#}10{#/blank#}(try) to cut trees. "

    Roofs and windows of buildings aren't the only surfaces that can be used to produce solar power. In China,{#blank#}1{#/blank#}（construct）has begun of the country's first solar highway, in which solar panels are placed underneath transparent concrete.

    The solar highway is a 2 km stretch（一段）of road{#blank#}2{#/blank#}（lie）on the Jinan City Expressway, and it's divided into three layers. The see-through concrete protects a set of solar panels of two{#blank#}3{#/blank#}（size）. Beneath the solar panels{#blank#}4{#/blank#}（be）a layer that separates them from the damp ground.

    The road{#blank#}5{#/blank#}（it）has already been completed, and now it's only a matter of connecting the grid（输电网）,{#blank#}6{#/blank#}is expected to be finished by the end of the year alongside the completion of the Jinan Expressway's south section.

    This isn't the first solar road China has worked on. Earlier this year, the Qilu Transportation Development Group, also handling the Jinan Expressway solar road,{#blank#}7{#/blank#}（build）a 160-meter- long solar road in{#blank#}8{#/blank#}city of Jinan. It has the ability of heating up to keep the highway clear{#blank#}9{#/blank#}snow and ice* and is able to{#blank#}10{#/blank#}（wireless） charge electric vehicles. The new solar highway is expected to one day be equipped with the same features.
