在长江河口和东海交汇处，有一片完全原生态湿地——九段沙，被人称为“上海最后的处女地”20世纪60年代才露出水面，动植物的“______”。

走在______的木栈道上，两旁的芦苇高过头顶。偶尔眼前开阔了些，是尺把高的海三棱藨草，在阳光下娇羞挺立着。旁边一片窸窸窣窣声，定睛一看，受惊的小螃蟹纷纷躲藏，芦苇下的滩涂上只剩下的______小圆洞。走过漕沟，泥滩上，突然有两指长的“泥土”滑向水里，那是弹涂鱼，不细看根本分辨不出。远远的，芦苇丛中两个白点，尚未走近，白点扇起了翅膀，腾空而起，飞远了。哦，是白鹭！视线还未收回，一只黑白相间的鹡鸰，以独有的波浪起伏的飞行姿态，从空中掠过。

这里，便是九段沙湿地。主人正是那些自由生长的动植物。九段沙湿地具有宝贵的生态价值，由长江泥沙沉积而成，九段沙湿地是长江南支河段中最年轻未开发的“处女地”，也是国内惟一基本保持原始河口沙洲地貌及发育过程的重要地区。九段沙湿地处在海洋、河流、陆地三大生态系统相互作用中，是呈自然演替状态下的典型河口型潮汐滩涂湿地，对研究地球生物演进和生物多样性保护意义重大，“保九段沙，要有所为，有所不为。"孙瑛告诉记者。对这个保护区，整个团队的行为都十分克制。管理成立15年来，九段沙依然“______”，天然去雕饰。

Last Monday,……

    It's after 10 a.m. and the kids are still sleeping. It's Sunday. This is a traditional day of 1.

    Every culture on the planet has 2 one day of rest a week.  Some use that time to go church, 3 others sleep, watch TV, and just give themselves the gift of a 4 day. And there are those who 5 that working up a sweat in the backyard is just what the doctor ordered, but I 6 that exact activity.

    We need to give ourselves a break, and a little rest 7 well for almost everybody. It doesn't 8 matter what the activity is. The idea is to give your body, mind, and heart a(n) 9 to relax. If you keep going at full speed every day, it can be really 10 on you, both physically and mentally.

    Some people 11 it hard to take a real vacation, let alone a day off. I have seen many people work themselves 12 an early grave because they were too13, and some too scared to give themselves a break.

    It doesn't matter what 14 your free time takes. You 15 yourself the gift of a deep breath and a view of the long sunset. Remember that you can't work well if you're exhausted (精疲力竭) by 16 stopping to take a rest. Again, it doesn't matter 17you do it. This is not about tradition. Find out whatever time works best for you, and 18 a plan.

    19 this and talk it over with others. The idea here is that by giving ourselves a break and just 20 a day off, we can make our lives better and actually create greater things in our world.

近日，清华大学政治系副教授刘瑜坦言：“正确的教育不是非要把一颗小草培养成参天大树，而是要把小草培养成一颗美好的小草，一颗健康的小草。”这让很多人想起俞敏洪的“大树小草说”：人的生活方式有两种，第一种是像草一样活着。你尽管活着，每年还在成长，但是你毕竟是一颗草……我们每一个人都应该像树一样成长。……当你长成参天大树以后，遥远的地方，人们就能看到你，走近你，你能给人一片绿色、一片荫凉，你能帮助别人。树，活着是美丽的风景，死了依然是栋梁之才。

综合以上材料，你有怎样的思考与认识？请写一篇文章，谈谈自己的看法。

    When I was in high school, most of my friends had bicycle. I hoped I could also have it. One day I saw a second-hand bicycle, that was only one hundred yuan. I asked my father the money.

    And he said he could only give me half of the money. I should find the other half myself. So I went to sell newspapers after the school. My father was please when I showed him the money a month after. He gives me the other fifty. You can imagine how happily I was when I rode to school on my own bicycle.

    To find out how the name Canada came about we must go back to the 16th century. At that time, the French dreamed of discovering and controlling more land, of expanding(扩大) trade beyond their borders and of spreading their beliefs across the world. In 1535, Francois I, king of France, ordered a navigator(航海家) named Jacques Cartier to explore the New World and search for a way to India.

    Carrier first arrived at the gulf of the St. Lawrence, which he intended (打算) to explore. He did not know what to expect but he hoped that this gulf was just an arm of the ocean between two islands. If it was, he would soon be on his way to the Far East. So he sailed upstream along the St. Lawrence River. However, instead of reaching Asia he arrived at Quebec or Standalone, as the Indians called it. It was at this point that the term "Canada" entered the country's history. Apparently the word "Canada" came from an India word" kanata", which means community or village. Cartier first used it when he referred to Standalone or Quebec. What a huge "village" Canada is!
