Unit 5 Into the wild 教材助读-【优学精讲】2026-2027学年高中英语必修第一册教用课件（外研版）

该高中英语单元复习课件围绕“Into the wild”主题，系统梳理了自然迁徙与野外邂逅两大语篇的核心词汇、语法及语篇知识。通过“读文清障”模块分点解析重点词汇（如annual、seek）、短语搭配（in search of、manage to do sth.）及语法点（定语从句、现在完成进行时等），结合原文翻译构建词汇-语法-语篇一体化知识网络。 其亮点在于采用主题情境化复习策略，以黑脉金斑蝶迁徙和摄影师遇熊语篇为载体，通过词汇用法对比（如somehow与anyhow）、语法结构标注（如where引导定语从句）等活动，培养学生语言能力与思维品质。分层设计涵盖基础词汇积累到复杂句型分析，助力不同水平学生巩固知识，教师可依托系统梳理精准开展复习教学。

This annual② movement is called migration. They migrate to find food, seek③ a partner, or in search of ④ warmer weather. One of the most wonderful⑤ migrations in nature is [1]that of the North American monarch butterfly． 读文清障 [1]此处作表语，其中that指代migration。 返回导航 　　Every autumn, millions of these beautiful insects⑥ with fine black and orange wings begin a long and difficult journey. Somehow⑦ they manage to⑧ travel around 4，000 kilometres south and find their way to California or Mexico. However, until recently no one knew [2]how they did this． [2]此处是how引导的宾语从句，作knew的宾语。 返回导航 　　A team of scientists [3]led⑨ by Professor⑩ Eli Shlizerman at the University of Washington has now found the answer. They have found out that the monarch is able to tell the time of day. It uses its eyes to measure⑪ the position⑫ of the sun. These two pieces of information—the time of day and the point where the sun is in the sky—allow⑬ the butterfly to determine⑭ the way to go. Eventually⑮， it manages to reach the places [4]where it will spend the winter． [3]此处是过去分词短语作后置定语，修饰A team of scientists。 [4]此处是where引导的定语从句，修饰先行词places，where在从句中作地点状语。 返回导航 The solution⑯ to the mystery of the monarch's amazing⑰ ability comes at a time [5]when it is in serious trouble. Its population⑱ 　　has crashed⑲ by as much as 90 per cent⑳ in the last few years. Sadly, human activity is the main reason [6]why the number of monarch butterflies is falling. [5]此处是when引导的定语从句，修饰先行词a time，when在从句中作时间状语。 [6]此处是why引导的定语从句，修饰先行词reason，why在从句中作原因状语。 返回导航 In many of the places where the butterfly can be found, people are destroying㉑ the natural environment. [7]They cut down㉒ trees and use chemicals㉓ that kill the plants that monarch caterpillars eat. [7]本句中两个that均引导定语从句。第一个that引导的从句修饰先行词chemicals，that在该从句中作主语；第二个that引导的从句修饰先行词plants, that在该从句中作宾语。 返回导航 　　The research on the monarch's behaviour㉔ has however led to a greater awareness㉕ of this creature㉖. [8]People have been working together to record its migration and make sure that there are enough plants for it to feed on. If this works, there may come a time when the number of monarch butterflies increases once again. [9]The more we know about this lovely creature, the greater the chance it will survive㉗ and keep its place in the natural world for a long time to come. [8]本句中have been working是现在完成进行时，表示动作从过去某个时刻开始，一直延续到现在，还可能延续下去。 [9]本句中“The more...，the greater...”是“the＋比较级．..，the＋比较级．..”结构，意为“越……，就越……”，表示后者随着前者的变化而变化。 返回导航 黑脉金斑蝶的 迁徙之旅 　　许多动物会在一年中的某些时候从一个地方迁移到另一个地方，这种一年一度的运动叫作迁徙。它们会为了寻找食物、伴侣，或者更温暖的天气而迁徙。北美黑脉金斑蝶的迁徙是大自然中最为美妙的迁徙之一。 原文翻译 返回导航 　　每年秋天，数百万只长着好看的黑色和橙色斑纹翅膀的美丽的昆虫(黑脉金斑蝶)会开始一段漫长而艰难的旅程。不知用了什么方法，它们设法向南飞行了大约4 000公里，找到了去往加利福尼亚或者墨西哥的路。但一直到最近，也没有人知道它们是如何做到的。 返回导航 　　由华盛顿大学伊莱·席里哲曼教授领导的科学家(研究)小组现在已经找到了答案。他们发现黑脉金斑蝶可以分辨出一天的时刻。它用眼睛来测量太阳的方位。这两条信息——一天中的时刻和太阳在天空中的方位——让黑脉金斑蝶确定它的飞行路线。最终它成功到达过冬的地方。 返回导航 　　黑脉金斑蝶在处于严重困境时，它惊人的能力的奥秘才得以解开。过去的几年里，黑脉金斑蝶的数量骤减了百分之九十之多。不幸的是，人类活动是黑脉金斑蝶数量下降的主要原因。在许多黑脉金斑蝶生存的地方，人们正在破坏自然环境。他们砍伐树木，使用能杀死黑脉金斑蝶幼虫食用的植物的化学药剂。 返回导航 　　不管怎样，对黑脉金斑蝶(迁徙)行为的研究让人们对这种生物有了更多的认识。人们一直齐心协力记录它的迁徙，并确保有足够的植物可供食用。如果这种做法起作用，那么可能到某个时候黑脉金斑蝶的数量会再次增加。我们对这种可爱的生物了解得越多，它生存的机会以及在未来很长一段时间内保持它在自然界中的地位的机会就越大。 返回导航 教材原文助读10 第二部分 21 ①encounter [In'kaʊntə] n．意外的相遇，邂逅 ②photographer [fə'tɒɡrəfə] n.摄影师 photograph n．照片；相片 v．拍照，照相 ③brave the elements不顾天气恶劣，冒着风雨 element ['elImənt] n．基本部分，要素 the elements天气(尤指坏天气) 词汇积累 读文清障 文本助解释疑 返回导航 ④despite [dI'spaIt] prep.即使， 尽管(＝in spite of) ⑤observe [əb'zɜːv] v．看到，观察 ⑥be famous for(＝be known for)因……而闻名/著名 be famous as(＝be known as)作为……而闻名/著名 ⑦variety [və'raIəti] n．多样化，变化；(植物、语言等的)变体；品种 a variety of/varieties of各种各样的…… ⑧wildlife ['waIldlaIf] n．野生生物 ⑨up to达到 返回导航 ⑩at a speed of...以……的速度(表示速度、价格等的单词，常常和at连用) ⑪path [pɑːθ] n．小径，小道 ⑫breathtaking ['breθˌteIkIŋ] adj.令人惊叹的 ⑬eagle ['iːɡ(ə)l] n．鹰 ⑭snow-capped adj.山顶积雪的 ⑮reflect [rI'flekt] v．映出(影像)；显示，反映；沉思 reflect on sth.认真思考某事 返回导航 ⑯still adj.静止的；平静的； [熟词生义]无风的 still water平静的水面 a still summer's day无风的夏日 ⑰concentrate ['kɒns(ə)ntreIt ] v.专注，专心 concentrate on专注于；集中注意力于；全神贯注于 ⑱scene [siːn] n．景色；景象 ⑲freeze [friːz] v．突然停止，呆住 ⑳stare [steə] v．凝视，盯着看 stare at盯着看 返回导航 ㉑button ['bʌtn] n．按钮 press the button按下按钮 ㉒recover [rI'kʌvə] v．(从糟糕经历中)恢复 ㉓shock [ʃɒk] n．吃惊，震惊；令人震惊的事；休克vt.(使)震惊；(使)惊愕 in shock震惊地；吃惊地 ㉔frightening ['fraItnIŋ] adj.可怕的；骇人的(多用来修饰事物) frightened ['fraItnd] adj.惊吓的；害怕的(多用来修饰人或人的表情、声音等) 返回导航 ㉕magical ['mædʒIkl] adj.奇妙的；令人愉快的；神奇的；有魔力的 magic n.

But despite④ the wind and the rain, I still enjoy working outside in the wild. One of the best things about this job is [1]that you can observe⑤ animals in their natural environment． 读文清障 [1]此处是that引导的表语从句。　 返回导航 　　My favourite place to take photos is Yellowstone National Park. As the world's first national park, Yellowstone is famous for⑥ the variety⑦ of its wildlife⑧， but it is probably best known for its bears. These huge, strong animals can live for 30 years. Despite a weight of up to⑨ 300 kilograms, they can run at a speed of⑩ around 64 kilometres per hour and are also excellent swimmers. 返回导航 　　Last spring in Yellowstone, I followed a path⑪ that took me through a dark forest. When I finally stepped out of the trees, the view was breathtaking⑫. An eagle⑬ flew over the snow-capped⑭ mountains, [2]which were reflected⑮ in the still⑯ lake below. [2]此处是which引导的非限制性定语从句，修饰先行词mountains，which在从句中作主语。 返回导航 [3]While I was concentrating⑰ on photographing this amazing scene⑱， I suddenly had a feeling that I was being watched. Slowly, and [4]with the camera still held to my eye，I turned...and froze⑲. [3]本句中“While I was...amazing scene”是while引导的时间状语从句；“that I was being watched”是that引导的同位语从句，解释说明feeling的内容；was being watched是过去进行时的被动语态，表示过去某时正在发生的被动动作。 [4]此处是“with＋宾语＋宾语补足语”结构，宾语补足语为过去分词短语“held to my eye”。 返回导航 [5]Only metres away from me was a bear. [6]With water falling off its thick, brown hair, the bear stared⑳ back at me. Time stood still [7]as the bear and I both waited to see who would move first. My legs started shaking. Somehow, I forced my finger to press the button㉑. A second later, the bear turned and ran back into the forest. When I recovered㉒ from the shock㉓， I looked at my camera. My most frightening㉔ but magical㉕ experience was now captured㉖ forever in a single image㉗． [5]本句是表语提前引起的全部倒装。 [6]此处是“with＋宾语＋宾语补足语”结构，宾语补足语为现在分词短语“falling off its thick, brown hair”。 [7]此处是as引导的时间状语从句；其中“who would move first”是who引导的宾语从句。 返回导航 　　From time to time I look at the photo as a reminder㉘ to show respect to all animals. [8]It is after all㉙ we who are the visitors to their world. [8]本句是强调句型，强调部分为句子的主语we。 返回导航 与自然的 不期而遇 　　作为一名自然摄影师，我必须得勇敢地面对恶劣天气。尽管风雨交加，我仍然喜欢在野外工作。这份工作最棒的地方之一就是你可以在动物生存的自然环境中观察它们。 原文翻译 返回导航 　　我最喜欢的拍照地是黄石国家公园。作为世界上第一个国家公园，黄石国家公园因园内野生生物的多样性而著名，但最为出名的可能是公园内的熊。这些体型庞大、身体强壮的动物寿命长达30年。虽然体重高达300千克，但它们却能以每小时约64千米的速度奔跑，并且它们还是游泳健将。 返回导航 　　去年春天，在黄石公园，我沿着一条小路穿过一片黑暗的森林。当我最终走出树林时，眼前的景色令人惊叹。一只鹰飞过白雪皑皑的群山，群山倒映在下方平静的湖面上。当我正专注于拍摄这个令人惊叹的场景时，我突然感到自己正在被注视着。我慢慢地转过身去，相机仍举在眼前……然后，吓呆了。在离我只有几米远的地方有一头熊。它回头盯着我，水正从它浓密的棕色毛发上滴落。时间静止了，熊和我都等着看谁先行动。我的腿开始颤抖。不知怎么地，我迫使自己的手指按下了快门。不一会儿，熊转身跑回了森林。当我从震惊中回过神来时，我查看了相机。我那最让人害怕却最不可思议的经历现在被永远地记录到了这张照片中。 返回导航 　　我会时不时地看看这张照片，以此来提醒我们要尊重所有动物。毕竟我们才是它们世界的访客。 返回导航 $
