There are a lot of famous women of {#blank#}1{#/blank#}（achieve）in the world. They all do {#blank#}2{#/blank#} ( good ) in their work, such as Lin Qiaozhi, Jane Goodall and Song Qingling. There is no doubt {#blank#}3{#/blank#} they are real heroines and {#blank#}4{#/blank#} ( worth ) of being praised. But in my opinion, all healthy humans have the ability to do that. It just depends on {#blank#}5{#/blank#} you have the determination to do it and whether the situation is in your favor. But never before have I admired a person so much {#blank#}6{#/blank#} Helen Keller, who I just read about. She was an unlucky girl, {#blank#}7{#/blank#} could neither hear {#blank#}8{#/blank#} see. I just can't imagine how she could be so successful. I really don't believe that a deaf-blind lady could become a world-famous writer. {#blank#}9{#/blank#} great difficulties she must have met and what great efforts she must have made. If I {#blank#}10{#/blank#} ( be ) her, I wouldn't have the courage to live on. It is by her courage and imagination and intelligence that I was struck.

    Many teachers believe that hands－on experience is the {#blank#}1{#/blank#}(good) way to learn. A group of students in the United States are putting that belief to the test. They {#blank#}2{#/blank#} (success) designed and built a robot for discovering unexplored mines {#blank#}3{#/blank#} the bottom of the sea. Students made the robot {#blank#}4{#/blank#}(answer) a challenge from the U．S. Department of Defense.

    The students recently tested the underwater vehicle {#blank#}5{#/blank#}(call) PerseusⅡin a 95－meter－long tank of water at the Stevens Institute of Technology.

    The robot costs about $15,000 to build. The students use a video game control to direct {#blank#}6{#/blank#}(it) movements in the tank. What's more, devices known as Japters {#blank#}7{#/blank#} (able) the robot to go up, down and toward its target in the water. Video cameras on the robot send images back to a computer through a 13－meter－long cable. Perseus Ⅱ,{#blank#}8{#/blank#}the students worked up to 20 hours a week to design and build, also has {#blank#}9{#/blank#} set of lasers (激光), which are used to measure the size of an object.

    DeLorme supervised the project from {#blank#}10{#/blank#}(begin) to end. He says the specialized requirements of robots were demanding.

    Two men travelling through a forest together promised {#blank#}1{#/blank#}(help) each other whatever danger threatened them. They had not gone far before a bear rushed at them from some bushes. One man was a good {#blank#}2{#/blank#}(climb), and quickly climbed a nearby tree, but the other,{#blank#}3{#/blank#}(see) that he had no chance alone against the bear, fell flat on his back and pretended to be {#blank#}4{#/blank#}(die).

    The bear came up to him and sniffed at him. Thinking the man was dead, he went off into the wood again {#blank#}5{#/blank#} hurting him. When the bear had gone, the other traveler came down from his tree, and {#blank#}6{#/blank#}(smile) asked his companion what the bear had said to him. "For I could see," he said, "that he put his mouth close to your ear."

    "He told me to tell you," {#blank#}7{#/blank#}(reply) the other, "that you were a coward（懦夫）, and that in future I should not trust those {#blank#}8{#/blank#} make fine promises, but will not stand by {#blank#}9{#/blank#}(they)friends in danger."

    Don't trust fine promise {#blank#}10{#/blank#} you are sure of the person who makes them.

    Your class starts in 10 minutes, but you find yourself {#blank#}1{#/blank#} (stick) in traffic. Don't panic. With just a press of a button, your car will lift off the ground and fly to school. What's your {#blank#}2{#/blank#} (impress)? It seems like science fiction, but it isn't. Engineers have taken {#blank#}3{#/blank#} the research of flying cars, and they have already found {#blank#}4{#/blank#} (solve) to many of the big challenges. They predict that we'll all be using these {#blank#}5{#/blank#} (amaze) vehicles one day. According to Car Trends Magazine, one model, {#blank#}6{#/blank#} is part car and part plane, is going to be on the market in the not-so-distant future. It will look like a regular car when it's on the road, but its wings will unfold when the driver {#blank#}7{#/blank#} (decide) to take to the sky. And {#blank#}8{#/blank#} (operate) by a computer, all controls will be automatic (自动的). Imagine this: You'll be doing your homework while your car is getting you to school {#blank#}9{#/blank#} (safe). And what does this future dream car cost? Well, at first it will be about a million dollars, but after a few years, you'll be able to buy {#blank#}10{#/blank#} for "only" $60,000. Don't throw away your old driver's license just yet!
