On December 19th, 2010, an airbus took off from the capital airport of Saudi Arabia. After about an hour's flight, something {#blank#}1{#/blank#} (believe) happened on the plane. The air hostess was about to serve lunch {#blank#}2{#/blank#} a small mouse stole out from the bag of a young man, which frightened the young woman nearby and she shouted loudly. Then more and more mice came out of {#blank#}3{#/blank#}bag. {#blank#}4{#/blank#}(catch) by surprise, the other passengers all shouted in panic. The steward managed to get in touch with the control center on the ground. With the order from the ground, the plane {#blank#}5{#/blank#}(success) landed at the nearest airport. As soon as the plane was on the ground, all the passengers got off. Then seven specialists got on the plane {#blank#}6{#/blank#}(kill) the mice. Many means had been tried but {#blank#}7{#/blank#} of them were good enough.

    At last, they tried to fill in the plane {#blank#}8{#/blank#} carbon-dioxide, which poisoned all the mice. It {#blank#}9{#/blank#} (report) that the young man wanted to carry the mice to another city and sell them as {#blank#}10{#/blank#}(pet), but he didn't expect they succeeded in escaping from the bag.

    Disposing(处理) of waste has been a problem since humans started producing it. As more and more people choose to live close together in cities, the waste disposal problem becomes {#blank#}1{#/blank#}(increase) difficult.

    During the eighteenth century, it was usual for several neighboring towns to get together to select a faraway spot{#blank#}2{#/blank#}a dump site(垃圾场). People {#blank#}3{#/blank#} (transport) household rubbish, rotted wood, and old possessions to the site. Regularly some of the trash was burned and the rest was buried. The {#blank#}4{#/blank#} (pleasant) sights and smells caused no problem because nobody lived close by. Factories mills (制造厂), and other industrial sites also had waste to be disposed of. Those located on rivers often just dumped the unwanted {#blank#}5{#/blank#} (remaining) into the water. Others built huge burners with chimneys to deal with the problem.

    Several facts make these choices {#blank#}6{#/blank#} (accept) to modern society. The first problem is space. Dumps,{#blank#}7{#/blank#}are now called landfills, are most needed in heavily populated areas. Such areas rarely have empty land suitable for this purpose. The land is either too expensive or too close to residential neighborhoods. A long distance dump has been a common practice,{#blank#}8{#/blank#} once farm areas are refusing to accept rubbish from elsewhere, cheap land within trucking distance of major city areas is nonexistent.{#blank#}9{#/blank#} (aware) of pollution dangers has resulted in more strict rules of waste disposal. Pollution of rivers, ground water, land and air is a price people can no longer pay to get rid of waste. The amount of waste, however, continues to grow.

    {#blank#}10{#/blank#} (recycle) efforts have become commonplace, and many towns require their people to take part. Even the most efficient recycling programs, however, can hope to deal with only about 50 percent of a city's reusable waste.

    Everyone needs to know how to prevent a fire. It is also important to know what to do when it {#blank#}1{#/blank#}（break）out .

    Every year, over 11, 000 people {#blank#}2{#/blank#}（kill）or injured in house fires. These fires could have been avoided. Smokers who are {#blank#}3{#/blank#}（care）cause about 200 deaths and over 6,000 fires. More than half of those {#blank#}4{#/blank#} die in fires are poisoned or harmed by smoke.

    If fire happens, do not attempt to fight the fire unless it is small. Try putting out a small fire with water. If {#blank#}5{#/blank#} fire has spread or if the flames are more than 20 inches high, shut the door on it. Warn everyone else in the building and tell them to get out. You should leave and dial 119for the fire department.

    Before {#blank#}6{#/blank#}（go）into a room, check the door. If the handle or the door is hot, do not open it! Instead, put clothing or a wet towel at the bottom of it to keep smoke out. If the door is not hot, open it {#blank#}7{#/blank#}（slow）. If there's a rush of smoke or heat, close it again and shout to warn {#blank#}8{#/blank#}（other）in side.

    Now open the window and shout “Fire!”. See whether you can drop safely to the ground. Use this {#blank#}9{#/blank#} your escape course if you can. If you are not on ground level, break your fall by pushing a mat out first. Lower yourself at arm's {#blank#}10{#/blank#}（long）before dropping. Once outside, stay outside and make sure the fire department is called.

    Ballet is a formal kind of dance performance with a rich and interesting history. The word "ballet" comes from the French language, and {#blank#}1{#/blank#} (be) based on the Italian word "balletto." "Balletto" means a little dance. Ballet's early roots began in Italy in the late 1400s. But it was in France {#blank#}2{#/blank#} ballet developed into the form we know today.

    The French ruler Louis the Fourteenth had a big influence {#blank#}3{#/blank#} the direction of ballet in its early history. He ruled France for seventy-two years, {#blank#}4{#/blank#} (start) in 1643. He started dancing as a boy and worked hard daily.

    Louis the Fourteenth turned ballet into a form of dance that reflected {#blank#}5{#/blank#} (he) power and influence. Ballet's many rules and {#blank#}6{#/blank#} (extreme) detailed movements expressed a person's power and social relations. The king made sure that ballet became a {#blank#}7{#/blank#} (require) for the people of his court. He also started the Royal Academy of Dance, {#blank#}8{#/blank#} important people could learn this art. The aim of this dance was self-control, order and perfection.

    Ballet slowly changed from a dance at the king's court to one {#blank#}9{#/blank#} (perform) by professional dancers. When Louis the Fourteenth died in 1715, ballet {#blank#}10{#/blank#} (bring) to other parts of Europe and was developing in other ways.

    Digital receipts offer a few improvements over {#blank#}1{#/blank#}(tradition) paper receipts. One is health-related. Lots of receipt paper contains bisphenol—A, or BPA. This chemical can completely influence or outright change some bodily processes, like hair growth, hormone function and cell repair. {#blank#}2{#/blank#} (reduce) receipt paper reduces the risk for BPA exposure for not only consumers but also for employees who handle the paper {#blank#}3{#/blank#} a more routine basis.

    Another reason why digital receipts are better just boils down to {#blank#}4{#/blank#} (convenient). You can access those receipts through your email and file {#blank#}5{#/blank#} (they) away in a separate folder or with a specific label for easy sorting. Or, if you need more help on the organization front, try a receipt tracking app. Physical receipts require you physically {#blank#}6{#/blank#} (keep) track of them, and that means a shoe box or an accordion folder or a big thumb tack on a cork board in the kitchen. There have been times when I've let something go unreturned {#blank#}7{#/blank#} I didn't have the receipt. I'm betting I'm not alone on that.

    Some businesses, particularly local ones, use newer point of sale systems like Square that will {#blank#}8{#/blank#} (automatic) send you a digital receipt if you've already received one from another business that uses Square. When you pay with the same credit you did at the first seller, and you've already provided {#blank#}9{#/blank#} email address to the Square system, you {#blank#}10{#/blank#} (get) a receipt in your email minutes later.
