They also give us the best trips. Today，there are nearly 7，000 national parks around the world. Forbes has listed 12 of the most beautiful ones in the world that will surprise you with their amazing landscapes，geographic wonders and colorful plants and animals. The Grand Ganyon（大峡谷） National Park of the US is one of the Seven Natural Wonders of the World. It is best known for its size and depth. It is 446 kilometers long，up to 29 kilometers wide and 6 kilometers deep. The immensity of the canyon makes people think big. Every year，about 5 million people visit here. Taking a tour in the South Rim offers visitors the park's full views，while the North Rim shows beautiful wild flowers. If you love animals，you'll like the Serengeti National Park in Tanzania. The"Big Five"live here. They are the lion，African elephant，African leopard，black rhinoceros and African buffalo. The name "Big Five" came from the five animals that were the hardest to catch. Now they are what people most want to see in the wild. If you visit the park，you should never miss the migration（迁徙） of over 5 million wildebeest（角马） and 250，000 zebras every year. This is the most famous sight of the park. （1）Which is NOT right about national parks according to Paragraph 1？ 　 　 A.Wild plants and animals are protected in national parks.

It makes it （1）　 　 like dreamland for me and I try to visit at least once a year. I've been （2）　 　 the ocean for at least 20 years. When I was （3）　 　 ，I would pick up shells and rocks，and bring them back home. So I had tons of them in my room.（4）　 　 ，as I visited the ocean more and more，I started picking up the （5）　 　 left by people instead of picking up ocean treasures. I made such a change after I （6）　 　 myself about my old habit. It helped me （7）　 　 that a stone you find in the ocean has a wonderful colour that makes you pick it up. But then，（8）　 　 it dries，you don't find it lovely anymore，so （9）　 　 pick it up in the first place？Anyway，I came to understand that natural things are （10）　 　 in their natural surroundings（环境） and that if everybody picked every shell from the ocean and （11）　 　 the litter out there，the beach would become something not so nice very shortly. So I made a （12）　 　 that day—I would just "borrow" things from the ocean and bring them back after a while，since the （13）　 　 of shells does so much good for me. I （14）　 　 the quantity（数量）and kept it to a minimum（最少量）. So if you've seen a lady picking up litter and （15）　 　 shells back into the ocean，from a box or a bag，don't be surprised!

They are very important for the environment，especially in slowing global（全球的） warming. According to a new study，planting a trillion（万亿） trees could stop global warming for 20 years. The study shows there is enough tree﹣planting land to make a 20﹣year stop in global warming. The study has also found that tree planting will be the most useful and cheapest way to make a difference to climate change and that it can take away plenty of CO2 which has been created by human activities. "When yon think about completing the project，it's not only about fighting climate change，but also about keeping ecosystems（生态系统） working well，"said Jean﹣Francois Bastin，one of the researchers in Switzerland. The study was made public just before Australia's National Tree Day. It has developed to be Australia's biggest tree planting and nature protection event. Researchers have found there are six countries that have more than half of the suitable land for planting trees. Among those six countries，Russia，the US and Canada have the most tree﹣planting land，followed by Australia，Brazil and China. It's clear that planting enough trees can make a great difference to the world. Everyone is expected to plant as many trees as possible. Part 2: Skills Challenge Task 1: Critical Thinking（批判性思维） 1. Why is planting trees a great way to fight global warming? (Use "because" to answer) _____________________________________________________________________________________ 2. List TWO advantages of tree planting mentioned in the text. _____________________________________________________________________________________ _____________________________________________________________________________________ 3. Design an English slogan to encourage people to plant trees.（要求：简洁押韵，体现植树的意义） _____________________________________________________________________________________ Task 2: Creative Project（创新应用） As an environmental club member, design a plan to encourage classmates to plant trees. Requirement 1: Include 1 action from the text（如Plant trees on suitable land, share the study about tree planting等）. Requirement 2: Add 2 creative ideas（如Organize a "class tree-planting day", set up a "tree growth record wall"等）. Requirement 3: Explain your plan in English（至少2句话，说明措施如何帮助鼓励同学植树）. _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ Task 3: Vocabulary & Inference（词汇与推理） 1. What does "suitable" mean in the sentence "Researchers have found there are six countries that have more than half of the suitable land for planting trees"? A. Expensive B. Fit C. Dry D. Small 2. Why does Jean-Francois Bastin say tree-planting project is "not only about fighting climate change"?（提示：从文中“but also about keeping ecosystems working well”推导逻辑关系） ( 1 / 7 ) 学科网（北京）股份有限公司 $ Unit 7 The natural world 课时3 Reading 2 分层作业 核心知识速记 03拓展培优 01基础达标 05思维进阶 02能力提升 ( 词形变化 1. sadly—( 形容词 )sad 2. harm—( 形容词；有害的 )harmful—( 形容词；无害的 )harmless 重点 句型 1.

A. Moreover B. However C. Instead D. Otherwise 【答案】 1. 答案：D 解析：“prevent sb. (from) doing sth.”是固定搭配，意为“阻止某人做某事”。句意为“当老师讲课时，我最好的朋友总是阻止我做作业”，符合语境；“advise”常用“advise sb. to do sth.”；“suggest”常用“suggest doing sth.”或“suggest that sb. (should) do sth.”；“finish”不符合此处阻止做作业的表意。 2. 答案：C 解析：第一空“look”是系动词，后接形容词作表语，所以用“sad”；第二空“look at”是实义动词短语，要用副词“sadly”修饰动词“look”，表示“悲伤地看”。 3. 答案：A 解析：“百分数 + of + 名词”作主语时，谓语动词的单复数由名词决定。第一空“students”是复数，所以用“are”；第二空“work”是不可数名词，所以用“is”。 4. 答案：C 解析：“take in”有“吸入”的意思，符合“在公园吸入新鲜空气”的语境；“take up”意为“占据，开始从事”；“take down”意为“取下，记下”；“take off”意为“起飞，脱下”。 5. 答案：A 解析：“do what we can to do sth.”表示“尽我们所能做某事”，“prevent sb. from doing sth.”（from可省略）表示“阻止某人做某事”，所以第一空用“to prevent”，第二空用“killing”。 6. 答案：A 解析：“living things”表示“生物”；“keep alive”表示“保持存活”。“lively”意为“活泼的”，“alive”常作表语或补语，“living”可作定语或表语，此处第一空用“living”修饰“things”，第二空用“alive”。 7. 答案：A 解析：“therefore”意为“因此，所以”，表示因果关系，符合“他到车站晚了，所以错过了早班火车”的逻辑；“because”表原因，后接从句；“however”表转折；“moreover”表递进。 8. 答案：B 解析：“fun”是不可数名词，所以不能用“a”修饰，排除A、D；“such + 形容词 + 不可数名词”，“so + 形容词 + a/an + 可数名词单数”，此处“weather”是不可数名词，所以用“such fine”。 9. 答案：D 解析：“if”引导的条件状语从句，遵循“主将从现”原则，所以主句用一般将来时，排除A、B；“比较级 + and + 比较级”表示“越来越……”，“less and less”表示“越来越少”，符合“湿地消失，动物生存空间越来越少”的语境，“little and little”表述错误。 10. 答案：A 解析：“moreover”意为“此外，而且”，表递进，符合“它更便宜，而且还节省很多能源”的语境；“however”表转折；“instead”表替代；“otherwise”表否则。 五、阅读理解。 National parks are large areas of public land.

The study shows there is enough tree﹣planting land to make a 20﹣year stop in global warming. The study has also found that tree planting will be the most useful and cheapest way to make a difference to climate change and that it can take away plenty of CO2 which has been created by human activities. "When yon think about completing the project，it's not only about fighting climate change，but also about keeping ecosystems（生态系统） working well，"said Jean﹣Francois Bastin，one of the researchers in Switzerland. The study was made public just before Australia's National Tree Day. It has developed to be Australia's biggest tree planting and nature protection event. Researchers have found there are six countries that have more than half of the suitable land for planting trees. Among those six countries，Russia，the US and Canada have the most tree﹣planting land，followed by Australia，Brazil and China. It's clear that planting enough trees can make a great difference to the world. Everyone is expected to plant as many trees as possible. Part 2: Skills Challenge Task 1: Critical Thinking（批判性思维） 1. Why is planting trees a great way to fight global warming? (Use "because" to answer) _____________________________________________________________________________________ 2. List TWO advantages of tree planting mentioned in the text. _____________________________________________________________________________________ _____________________________________________________________________________________ 3. Design an English slogan to encourage people to plant trees.（要求：简洁押韵，体现植树的意义） _____________________________________________________________________________________ Task 2: Creative Project（创新应用） As an environmental club member, design a plan to encourage classmates to plant trees. Requirement 1: Include 1 action from the text（如Plant trees on suitable land, share the study about tree planting等）. Requirement 2: Add 2 creative ideas（如Organize a "class tree-planting day", set up a "tree growth record wall"等）. Requirement 3: Explain your plan in English（至少2句话，说明措施如何帮助鼓励同学植树）. _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ _____________________________________________________________________________________ Task 3: Vocabulary & Inference（词汇与推理） 1. What does "suitable" mean in the sentence "Researchers have found there are six countries that have more than half of the suitable land for planting trees"? A. Expensive B. Fit C. Dry D. Small 2. Why does Jean-Francois Bastin say tree-planting project is "not only about fighting climate change"?（提示：从文中“but also about keeping ecosystems working well”推导逻辑关系） 【答案】 Task 1: Critical Thinking（批判性思维） 1. Because trees can take in CO₂ in the air around the earth and slow global warming, and a new study shows planting a trillion trees could even stop global warming for 20 years. 2. Advantage 1: It can stop global warming for 20 years when planting a trillion trees. Advantage 2: It is the most useful and cheapest way to make a difference to climate change and take away plenty of CO₂ from human activities. 3. Plant trees today, cool our world always; Less CO₂, a future bright and free. Task 2: Creative Project（创新应用） First, we will share the new study about tree planting (such as "planting a trillion trees could stop global warming for 20 years") to let classmates understand the importance of tree planting. Then, we will organize a "class tree-planting day" to let each classmate plant a small tree in the school's green area, and set up a "tree growth log" where everyone can write down the growth changes of their trees every two weeks. This plan helps classmates turn the knowledge of tree planting into practical action, and the growth log can keep their attention on the trees, further enhancing their enthusiasm for protecting the environment. Task 3: Vocabulary & Inference（词汇与推理） 1. B 2. Because Jean-Francois Bastin thinks the tree-planting project has another important purpose besides fighting climate change—it can also keep ecosystems working well, so he says it is "not only about fighting climate change".
