教材 人教版Go for it! 对应章/课时 Unit 7 /6
你敢挑战吗？ 这个单元将带我们开启一场“世界之最”的探险！我们会用英语学习地球上最令人惊叹的自然奇观——最高的山峰、最长的河流、最深的湖泊，以及和这些奇迹相关的动物、文化和环境保护知识。比如： - 你知道珠穆朗玛峰的真实高度吗？它为什么被称为“世界之巅”？ - 大熊猫为什么是中国的“国宝”？它们的生活环境面临哪些挑战？ 学完本单元，你将学会用“比较级和最高级”描述自然奇迹（如“更高、最深、最古老”），掌握地理数字与环保词汇，通过听说读写任务，自信讨论自然景观、动物保护，甚至用英语制作“世界之最”海报，最终理解：保护地球不仅是知识，更是责任！你还要用英语为濒临灭绝的动物们撰写求救信，呼吁更多的人来保护他们。你，敢挑战吗？
你将学哪些知识？
期望你学会什么？ 1 、在特定情境中谈论中国和世界的“自然地理之最”；用所学比较级和最高级与他人口头交流地理和自然景观的相关信息，有效询问，恰当表达，完成交际任务；围绕相关主题口头或书面语篇形式转述语篇的主要内容和观点。（语言能力） 2、通过比较，了解中国及世界地理知识；通过搜寻具体信息，培养寻读能力；通过罗列事实及数据，初步学习说明文写作。（学习能力） 3、能归纳总结语篇的主要内容、思想和作者的观点;能发现语篇中罗列的事实和数据,初步学习说明文的写作方法。（思维品质） 4、了解我国和世界的“自然地理之最”；了解珠穆朗玛峰及人类克服困难、挑战极限的精神；了解国宝大熊猫与动物保护 。（文化意识）
给你支招 一、词汇学习方法 1. 主题词汇分类记忆：将单元词汇按主题分类（如污染类型：air/water/noise pollution；环保措施：recycle/reduce/reuse；能源类型：solar/wind energy）。你可以制作思维导图，用不同颜色标注类别，结合图片联想记忆。 2. 词块学习法：记忆固定搭配（如：take action to do, protect the environment, throw rubbish into rivers）。 你可以用词块造句，例如："We should take action to stop cutting down trees." 二、本单元内容在语法上与八年级上册第三和第四单元紧密相关；在话题上与七年级下册第五单元紧 密相关。因此，在学习的过程中，你要复习整合以上单元的内容。如复习巩固形容词和副词比较级和最高级的变化规则，学习他们的特殊用法；深入关于环境保护和爱护动物的话题。 形容词和副词的变化规则是本单元的一个难点，因此你需要掌握较好的方法对他们进行记忆。你可以制作“形容词三阶变化表”（原级---比较级---最高级）进行汇总记忆，注意要用不同颜色标注规则和不规则变化。 形容词和副词的最高级句型结构是本单元的学习重点和难点，你可以通过仿写句子突破这一难点，注意仿写时要紧扣单元主题，例如：Air pollution is the most serious environmental problem in our area.

Here are five ways we think Venus is different： Volcanoes (火山) There are more volcanoes on Venus than those on the earth. There are more than 1，600 volcanoes on its surface (表面)，but there are possibly many more smaller ones that we can't see.Scientists believe that most of these are not active，though a few may still be active. Longer day than year A day on Venus lasts 243 earth days，while a year on Venus is shorter，at just 224.7 earth days.If that's just one day，think about what a work week would be like! High temperatures and pressure Temperatures on the surface can reach up to 470 degrees. The air pressure on the surface of Venus is very high—about 90 times higher than the pressure on the earth.In other words，the pressure on Venus is about the same as the water pressure on the earth. Russia sent a special machine to Venus.It took many photos of the land on Venus.But it did not stay long after landing because of the temperature and pressure. A windy planet Winds on Venus are strong and fast.They are faster than the fastest tornado (龙卷风) on the earth.Scientists say the winds on Venus blow so fast that they can drive clouds around the whole planet in four earth days. ( )1.Venus is the ________ planet from the Sun. A．first B．second C．third D．fourth ( )2.Which of the following is TRUE A．The earth has more volcanoes than those on Venus. B．There are 1，600 volcanoes are active. C．Most of the volcanoes on Venus are active. D．Some of the volcanoes on Venus are very small.

It is about 9 600 000 square kilometers in size. This is almost the size of the America or China. The desert covers eleven countries in the north of Africa. The Nile runs through the Sahara Desert all year round. But there are also other rivers running through it seasonally (季节性地). The geography of the desert includes huge sand dunes (沙丘) and dune fields. Some of the sand dunes are 80 huge that they can even be over 152 meters high. But there are also other amazing landforms (地形) in different parts of the desert. It is very hot and dry in the Sahara Desert. The temperature there is usually 30℃. However, during the hottest months, the temperature can go over 50℃. Because of the high temperatures and poor conditions of the desert, only a few plants live here, just about 500 kinds. They also play a role in the number of animals. In the driest part of the desert, there are only 70 different kinds of animals. Today the Sahara’s population is around four million. They move from place to place through the desert. Because of this there are many different cultures and languages in this area. ( )6.
