单选题Whether you are hiking (徒步) through the magnificent redwoods of Northern California, sleeping under the brilliant stars of the Texas sky or watching the sun rise across the rocky cliffs of Maine, expecting the outdoor world can be inspiring, thrilling, and deeply satisfying. And one of the best ways to enjoy the abundant gifts of the natural world is simple, inexpensive, and available to almost everyone. Let"s go camping. When you camp, you create a "home away from home" in the fresh air. You don"t need a lot of fancy equipment to enjoy camping. What you need is simply a tent large enough for your family. Practice setting up the tent at home to make sure you are familiar with the process before you go camping. Once you find a good site, it"s time to set up the tent. Your first job is to set up your tent. Remove all sticks and rocks from the area. Spread a tarp (防水帆布) over the area where your tent will sit. Set up the tent and be sure to stake it down firmly, even if the weather is mild. Otherwise, strong wind can blow your tent away. Next, you"ll need some firewood for a campfire. If gathering wood is illegal at your campground, you must buy it at the camp store. If gathering dead wood is permitted, go on a firewood-hunting journey and bring in a good supply of wood for your campsite, pile the wood safely away from the campfire ring and where no one will trip over the wood or hurt his or her legs on sharp branches. Being a responsible camper requires that you follow the rules of the campground. Do not burn food or plastic in your campfire. Make sure that you leave your campsite in good condition for the next campers. Just before leaving the site, make a final check to be certain that your campfire is completely out. Pour water on the ashes just to be safe!

单选题Washington Irving was America"s first man of letters to be known internationally. His works were received enthusiastically both in England and in the United States. He was, in fact, one of the most successful writers of his time in the country, and at the same time winning the admiration of fellow writers like Scott in Britain and Poe and Hawthorne in the United States. (78) The respect in which he was held partly owing to the man himself, with his warm friendliness, his good sense, his urbanity, his gay spirits, his artistic integrity, his love of both the Old World and the New. Thackeray described Irving as "a gentleman, who, though himself born in a very high sphere, was most finished, polished, witty; socially the equal of the most refined Europeans. " (79) In England he was granted an honorary degree from Ox- ford-an unusual honor for a citizen of a young, uncultured nation—and he received the medal of the Royal Society of Literature . America made him ambassador to Spain. Irving"s background provides little to explain his literary achievements. As gifted but delicate child, he had little schooling. He studied law, but without zeal, and never did practice seriously. He was immune to his strict Presbyterian home environment, frequenting both social gatherings and the theater.
