The city of the future

What will the city of the future look like? No one knows for sure, and making predictions {#blank#}1{#/blank#}(be) a risky business. But one thing is certain —they are going to get bigger before they get smaller. We will use lots of {#blank#}2{#/blank#}(recycle) materials, such as plastic aluminums, steel , glass ,wood and paper, and we will waste fewer {#blank#}3{#/blank#}(nature) resources. We will also have to rely more {#blank#}4{#/blank#}alternative energy, such as solar and wind power.

    A teacher at {#blank#}5{#/blank#} university in the United States asked his students to think {#blank#}6{#/blank#} they would run a city of 50,000 people in the year 2025. Here are some of the ideas they had:

    Garbage ships  To get rid of garbage problems, the city will load huge spaceships with waste materials and send them towards the sun,{#blank#}7{#/blank#} (prevent) landrills and environmental problems .

    Cars  All cars will be powered by electricity, solar energy or wind , and{#blank#}8{#/blank#}will be possible to change the color of cars at the flick of a switch.

    Telesurgery  Distance surgery will become common as doctors carry out operations from thousands of miles away, with each city {#blank#}9{#/blank#}(have) its own telesurgery outpatient clinic.

    Holiday at home  Senior citizens and people with disabilities will be able to go anywhere in the world using high-tech cameras {#blank#}10{#/blank#}(attach) to their head.

    The best way to deal with sports injuries is to keep them from happening in the first place. Knowing the rules of the game you're playing and using the right {#blank#}1{#/blank#}(equip) can go a long way toward preventing injuries. If you think you've been injured, pull {#blank#}2{#/blank#}(you) out the game or stop {#blank#}3{#/blank#}(do) your activity or workout. Let a coach or parent know what happened in case you need to see a doctor. Serious head and neck injuries happen most often in athletes {#blank#}4{#/blank#} play body-contact sports like football. Keep the injured person still with his or her head {#blank#}5{#/blank#} (hold) straight while someone calls for emergency {#blank#}6{#/blank#}(medicine) help. If the person {#blank#}7{#/blank#}(lie) on the ground, do not try to move him or her.

    Your first question after a sport injury will {#blank#}8{#/blank#}(probable) be, “When can I play again?” This depends on the injury and what your doctor tells you. Even if you can't return to your sport right away, a doctor might have suggestions and advice {#blank#}9{#/blank#} what you can do to stay fit. Always check with your doctor {#blank#}10{#/blank#} trying any activity following an injury.

    Paul Lucas can often be seen walking around the city of San Francisco. Sometimes people are {#blank#}1{#/blank#} (surprise) to see him walking without any shoes or socks,{#blank#}2{#/blank#} Lucas doesn't mind at all. He likes to walk barefoot, and {#blank#}3{#/blank#} do 640 other members of Dirty Sole Society, the club that Lucas {#blank#}4{#/blank#} (start) years ago. Lucas' idea for this is to encourage others to live {#blank#}5{#/blank#} (free)－free of shoes.

    According to Lucas, the barefoot life has many {#blank#}6{#/blank#} (advantage). The most important is simply that it feels good. He also says that walking barefoot allows you to experience the world directly by {#blank#}7{#/blank#} (touch) it with your feet. In addition, the feet do not smell so much {#blank#}8{#/blank#} they stay dry,{#blank#}9{#/blank#} (make) it hard for bacteria(细菌)  to grow. And, of course, walking barefoot keeps your feet in good shape, so it's actually {#blank#}10{#/blank#} (healthy) than wearing shoes.

    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.

    Students are busy. Between classes, work, homework and family, there can be a lot to balance. So why would we suggest that you add another thing to that list by {#blank#}1{#/blank#} (join) a student organization? First of all, it presents many opportunities to learn more about {#blank#}2{#/blank#} (you), your goals, and your strengths. You can also find out what you're good at, whether that's listening, staying organized, or serving others. This self-awareness {#blank#}3{#/blank#} (be) beneficial in your future career.

After a lot of preparation, Joseph Lockwood and Philippa Amos were finally ready to start their journey into the Amazon rainforest. They were feeling {#blank#}1{#/blank#}(cheer) as they sailed down the great river. Eventually, they got out of the boat and walked into the darkness of the jungle. Neither of them had ever been in such an extreme situation before, using just a compass (指南针) to find the area where the kind of frog they wanted to study {#blank#}2{#/blank#} (live). Suddenly, Joseph, who was holding the compass, tripped and lost it in a river. The situation seemed hopeless—how would they find the frogs now? But just {#blank#}3{#/blank#} they started to feel really sad and worried that their journey {#blank#}4{#/blank#} (be) a failure, they saw the frogs they had come to look for.
