Five tips for less plastic

　　The world has a plastic problem---and it is increasing. Scientists are working to find a long-term solution by making plastic more biodegradable(可生物降解的). But in the meantime, here are five things you can do to r 81 plastic waste now.

　　1. Stop using plastic bags. Instead, take your own reusable shopping bag to the store. People use a trillion plastic bags worldwide every year. About 10 percent are used in the United States alone. That’s almost one bag per American per day. but the a 82 Dane(丹麦人)uses four single-

　　use bags per year. In 1993, Denmark was the first country to place a tax on plastic bags. Today, other

　　countries(such as Chile, Kenya and New Zealand)either make customers pay for plastic bags, or have banned(禁止)them c 83 .

　　2. Skip the straw. Today, around 8.3 billion plastic straws pollute the world’s beaches. So when you order a drink, say“no”to the reusable straw, or bring your own reusable one. In 2018, Seattle

　　became the first major U.S. city to ban plastic straws and many other cities are set to follow its e 84 .

　　3. Don’t use plastic bottles. Buy a reusable bottle and fill it with any t 85 of drink you like. Some cities have already banned bottled water. However, people still buy nearly a million plastic bottles every minute in the world.

　　4. A 86 plastic packaging. Buy bar soap instead of liquid soap in plastic containers. Don’t buy fruit or vegetables in plastic packaging. In the U.K, leaders are calling for supermarkets to have plastic-free areas. They also want to tax plastic take-out containers.

　　5. Recycle. We can’t recycle all plastic items, but it is p_ 87 to recycle most bottles and milk or juice cartons. Today, Norway recycles 97 percent of its plastic bottles. How? Machines at most supermarkets take the bottles and give a refund of up to 2.5 kroner(32 cents)per bottle.

　　D. Answer the questions.

　　John Wesley Powell

　　Every time I go whitewater rafting, I think of an explorer named John Wesley Powell who was an amazing figure in the American West. Powell was fearless and thought nothing of hopping in a boat and rowing down an unknown river. Along the way, he studied geology, plants, and wildlife, teaching himself much about the natural world.

　　In 1860, Powell joined the army in the Civil War. He was injured and lost his right arm. When the wound was cured, he went back into battle! In 1865, He retired as a major(上校).

　　Powell took a teaching position as professor of geology even though he had never gone to college himself. During this time, he began to develop a daring plan. He wanted to explore the Grand Canyon by rafting the Colorado River. No one had done such a thing before.

　　In May of 1869, Powell set out with ten men on the Green River in Wyoming for a ten-month trip. Everyone who saw them leave though they would be done for.

　　No wonder! They were facing the unknown with every bend of the river. No one knew what rapids(急流)lay ahead or how dangerous they’d be. But Powell refused to give up. He had courage and carefulness. He did what he set out to do. He got a river’s-eye view of one of the most unbelievable natural formations(构造)on Earth. And he lived to tell the tatle.

　　88. Powell was afraid of hopping in a boat and rowing down a river, wasn’t he?

　　89. What happened to Powell’s right arm when he was in the army?

　　91. How many people set out on the Green River in Wyoming for a ten-month trip?

　　92. Why did everyone who saw them leave think they would be done for?

　　93. How does the writer feel about Powell? Please tell your reason(s).

　　Ⅶ. Writing.

　　94. Write at least 60 words about the topic “ left me a new impression.”(请以“ 给我留

　　下一个新印象”为题，写一篇不少于 60 个词的短文，标点符号不占格。)

　　你身边有熟悉的同学、朋友、老师……，有一天可能因为某件事让你对她(他)改变了原有的看法。请补全标题，并结合这个事例谈谈她(他)给你留下的这个新的印象。
