    Everyone has his own way of saying things and his own special expressions. Many everyday American expressions are based {#blank#}1{#/blank#} colors. Red is a hot color. Americans often use {#blank#}2{#/blank#}to express heat. They may say they are red hot about something unfair. When they are red hot they are very {#blank#}3{#/blank#}(anger) about something. The small hot tasting peppers found in many Mexican foods {#blank#}4{#/blank#}(call) red hots for their color and their spicy taste. Fast loud music is popular with many people. They may say the music is red hot,{#blank#}5{#/blank#} (especial) the kind called Dixieland jazz. Pink is a {#blank#}6{#/blank#}(light) kind of red. People sometimes say they are in the pink {#blank#}7{#/blank#}they are in good health. The expression was first used in America at the beginning of the {#blank#}8{#/blank#}(twenty) century. It probably comes from the fact that many babies are born with a nice pink color {#blank#}9{#/blank#}shows that they are in good health. Blue is a cool color. The traditional blues music in the United States is {#blank#}10{#/blank#}opposite of red hot music. Blues is slow, sad and soulful(深情的). Someone who is blue is very sad.

    Today, with most of us{#blank#}1{#/blank#}(own) a smartphone that lets us post to social media wherever and whenever we want, oversharing has become {#blank#}2{#/blank#}(hard) to avoid{#blank#}3{#/blank#} the tricky thing is {#blank#}4{#/blank#}people usually don't realize they{#blank#}5{#/blank#}(overshare) when they post information on the Internet. The problem can only{#blank#}6{#/blank#}(bring) to light by our friends and family.

    A survey showed that every two{#blank#}7{#/blank#}three people in the US think their friends share too much on social media.

    Oversharing can have{#blank#}8{#/blank#} (apparent) negative impacts. For starters, a leak（泄露）of personal information may put your bank account at risk. Plus, It may also jeopardize（危及）your current or future job if you, for example, trash-talk your{#blank#}9{#/blank#}(employ) on social media or write about how you got {#blank#}10{#/blank#} (drink) during office time.

    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.
