Some wild animals are disappearing from our planet forever at a surprising speed①. Scientists estimate② that the current rate of extinction is thousands of times greater than it would normally be because of one factor—humans. We are consuming the earth's natural resources faster than ever③. We destroy animals' habitats, food, water and air, as well as the animals themselves. We may consider the animal world to be separate from our own, but in fact, our lives and theirs are connected in several aspects. Plants, animals, people and the environment together make up④ a biological community—an ecosystem—in which each part depends on another for survival. When one part of the community is thrown off-balance(不平衡地) or disappears, the entire system will suffer. We may not be able to bring back the species we have already lost, but many others on the edge of extinction need our immediate⑤ attention and action. ❷Through cutting demands for animal byproducts, introducing laws against trafficking(非法贩卖), and volunteering in organizations that help protect endangered species, people fight with the threats the earth's wild animals are faced with. No act of protection is too small. Be the solution: Respect⑥ and protect the earth's wildlife. 【词块采撷】 ①at a surprising speed　以惊人的速度 ②estimate v．估计；判断 ③faster than ever 比以往更快 ④make up 组成；化妆；编造 ⑤immediate adj.立刻的；即时的 ⑥respect v．&n.尊重；尊敬；敬重 【亮句应用】 ❶as引导的定语从句 (2023·全国甲)Yet, the form of the fable still has values today, as Rachel Carson says in “A Fable for Tomorrow.”然而，正如雷切尔·卡森在《明日寓言》中所说，寓言的形式在今天仍然具有价值。 ❷动名词(短语)作介词宾语 (2024·1月浙江续写)Instead, she focused on reaching the shadow cast on the track by an oak tree up ahead.Then she concentrated on jogging to the spot where the track curved. 相反，她专注于到达前方一棵橡树在赛道上投下的阴影。然后她集中精力慢跑到跑道转弯处。 语言技能：①熟练运用本单元词汇以及句式；②学习定语从句(2)、后缀；③学习灾难求生的文章，学会如何在灾难中求生。 素养提升：①了解不同国家的自然景观、欣赏有关大自然的影视作品；②感受自然的力量、了解人对自然的探索以及学会如何实现人与大自然的和谐相处。 [教材原文] A SEA STORY About three years ago, something terrible happened to me.That was the day when it took only six hours to break my body and soul<1>．You think I am a very old man—but I am not.It took less than a single day to change my hair from black to white. One day, my two brothers and I were coming back from the islands where we often risked going and got more fish than others.All at once<2>， the sky was covered with dark clouds and in less than a minute we were in a terrible storm.A huge wave covered our boat and my younger brother fell into the sea.My elder brother put his mouth close to my ear and cried out “Moskoe-strom！”①The moment I heard the word I became very frightened<3>．I knew what he meant by that one word well enough. With the wind and waves, we were going in the direction of<4> the whirlpool.We were hopeless<5>．Nothing could save us.I felt sick, ②as if I was falling from a mountain top in a dream.We went round and round, nearer and nearer to the horrible<6> edge<7> of the whirlpool.It may appear strange, but at that moment, when we were on the edge of the whirlpool, I felt calmer than when we were moving towards it.I began to think how amazing a thing it was to die in such a way, and how wonderful it was to see the power of nature.Suddenly, we went over the edge.I thought my life was over.But moment after moment passed, and I was still safe. [词汇注解] <1>soul/səʊl/n.灵魂，心灵 <2>all at once 突然，忽然 <3>frightened/ˈfraItnd/adj.受惊的，害怕的 <4>in the direction of 朝着……的方向 <5>hopeless adj.无望的 <6>horrible/ˈhɒrəbəl/adj.可怕的，吓人的，令人恐惧的 <7>edge/edʒ/n.边缘 on the edge of 在……边缘；某事快要发生(尤指不好的事) 一个海上的故事 大约三年前，我遭遇了一件可怕的事情。那天，仅仅6个小时的时间我的身心遭遇重创。你以为我是个很老的人，但我不是。不到一天的时间，我的头发就从黑变白了。 有一天，我和我的两个兄弟又去了我们经常去探险的岛屿，抓到了比其他人更多的鱼。返回途中，突然，天空被乌云笼罩，刹那间，我们就被卷入了可怕的风暴中。我们的船被巨浪淹没了，我弟弟掉进了海里，我哥哥把嘴贴在我耳朵上，大喊：“莫斯肯漩涡！”①________________ ____________。我非常清楚那个词所代表的意义。 伴随着风浪，我们朝着漩涡的方向前进。我们非常无助。没有什么能救我们。我感到恶心，②____________ __________________。我们一直旋转，越来越靠近那可怕的漩涡边缘。看起来可能很奇怪，但在那一刻，当我们在漩涡边缘的时候，我觉得自己比向它移动时更平静。我开始想，这样死去是多么的令人惊奇，能看到大自然的力量是多么奇妙。突然，我们越过了边缘。我以为我的生命要结束了。但时间一分一秒地过去，我仍然是安全的。 好像在梦中从山顶上掉下来似的 The boat was on the inside of the huge whirlpool and we were going round in circles at great speed.I saw clearly that there were other objects in the whirlpool—trees and barrels<8>. After a while, I became curious<9> about the whirlpool itself.I then made three important observations<10>．The first, ③the larger the bodies were, the more rapidly they fell；the second, between two objects of equal<11> extent<12>， round objects fell down less rapidly; and the third, between two objects of the same size, objects shaped like a tube<13> fell down more slowly.So I tied myself to a barrel to help me float.④I tried to make my brother understand, but he was too frightened and stayed in the heavy boat.Without waiting, I jumped into the sea to try and escape. ⑤As you can see, the reason why I'm here to tell the story is that I made the right decision. Some time after I left the boat, with my brother in it, it was pulled into the bottom of the whirlpool.Soon after that, the whirlpool became less wild<14>．Then the sky was clear, the wind calmer, and the moon was shining.I was still tied to the barrel and the waves soon carried me to an area where the other fishermen were.In the end, a boat picked me up.I was very tired.The fishermen were my old friends, but they were unable to recognise me.When I told them my story, they did not believe it.Now I have told you, and I cannot expect you to believe me any more than the fishermen did. <8>barrel/ˈbærəl/n.桶 <9>curious/ˈkjʊəriəs/adj.好奇的 <10>observation/ˌɒbzəˈveIʃən/n．观察；观察结果 <11>equal/ˈiːkwəl/adj.相等的；相同的 <12>extent/Ikˈstent/n.面积；长度；范围；程度 <13>tube/tjuːb/n.圆管，管子；(伦敦)地铁 <14>wild adj.狂暴的；暴风雨的 船在巨大的漩涡里面，我们以极快的速度绕着圈子。我清楚地看到在漩涡里还有其他东西——树和桶。过了一会儿，我对漩涡本身产生了好奇。然后我有三个重要的发现。第一，③______________________；第二，两个面积相当的物体，圆形物体下落得更慢；第三，两个同样大小的物体，管状物体下落得更慢。所以我把自己绑在一个桶上帮助我漂浮。④_______________________________，但他太害怕了，留在了那条沉重的船上。我没继续等，就跳进了海里，尝试逃走。 ⑤___________________________________________ _________________在我离开后过了一会儿，那只载着我哥哥的船被卷入漩涡底部。没多久，漩涡就变得不那么疯狂了。然后天空放晴，风平静了下来，月亮在闪闪发光。我仍然跟木桶绑在一起，海浪很快把我带到了一个其他渔民所在的地方。最后，一条船上的人把我救了起来。我疲惫至极。那些渔夫是我的老朋友，但他们已经认不出我了。当我告诉他们我的故事时，他们并不相信。现在故事讲完了，我并不指望你能比那些渔民更相信我。 如你所见，我能在这里讲这个故事正是因为我做了正确的决定。 Step One　Fast reading Ⅰ.Read the passage quickly and fill in the following blanks with suitable words.
