Unit 4 Section B 2a～2c project 课件 2025-2026学年 人教版（2024）八年级英语上册

该初中英语课件围绕“神奇动植物”主题，聚焦形容词描述、名词后缀（-ance等）构成、最高级运用及信息提取，通过词汇分类（2a圈不同类词）、后缀构词（2b）等活动导入，逐步过渡到阅读提取青蛙习性等关键信息，搭建从词汇到语篇再到实践的学习支架。 其亮点在于融合语言能力与思维品质，项目制作（海报）要求小组选择“最神奇植物”等主题，收集信息并运用所学名词（如importance）和最高级描述，培养分析与创造思维。通过反思环节关联动植物与人类的联系，渗透文化意识，提升学生合作探究与知识迁移能力，教师可借助结构化活动高效实施教学。

Project: Make a poster about a plant or an animal  Please guess the animals’ name after reading other description. 4b Platypus /ˈplætɪpəs/ Its name is the ________. It lives in freshwater lakes and rivers in eastern Australia. I chose it because it's one of the only two mammals in the world that lays eggs instead of giving birth to live babies! It has a duck-like bill, a beaver-like tail, and webbed feet. Males even have a venomous（有毒的） spur on their hind feet! When the first specimen was sent to Europe, scientists thought it was a fake animal made from different parts. platypus 2. Project: Make a poster about a plant or an animal  Please guess the animals’ name after reading other description. 4b Koala /kəʊˈɑːlə/ Its name is the ________. It lives only in Australia, in eucalyptus（桉树） forests. I chose it because it looks like a lovely, soft teddy bear with big, round ears and a black nose. They sleep for up to 20 hours a day because their main food, eucalyptus leaves, provide very little energy. Their babies are called 'joeys'（幼兽） and live in their mother's pouch（育儿袋） for about six months. Koala 2. Project: Make a poster about a plant or an animal  Please guess the animals’ name after reading other description. 4b Pitcher Plant 猪笼草 Its name is the ________. It mainly grows in rainforests and tropical areas, such as parts of Southeast Asia and North America. I chose it because it's a carnivorous(食肉的) plant! It can "eat" insects, which is very unusual and amazing for a plant. It has a special leaf that forms a deep cavity(洞） filled with liquid. When an insect slips and falls in, it can't escape and the plant digests it. This helps the plant get nutrients that are missing from the soil where it grows. Pitcher Plant 2. Project: Make a poster about a plant or an animal  Please guess the animals’ name after reading other description. 4b peacock /ˈpiːkɒk/ Its name is the ________. They are native to forests in India and Sri Lanka(斯里兰卡), but now they live in parks and zoos all over the world. I chose it for its incredibly long and colorful tail feathers, which it can fan out into a stunning display. The beautiful "eyes" on a its tail are used to attract females and to scare away predators(捕食者). Despite their long and heavy tails, they can still fly short distances to escape danger or roost in trees. peacock 2. Project: Make a poster about a plant or an animal  Please guess the animals’ name after reading other description. 4b Great Basin Bristlecone Pine. 大盆地狐尾松。 Its name is the ________. It grows high in the mountains of the western United States, in very cold and dry conditions. I chose it because one tree of this species, named "Methuselah"(玛士撒拉), is over 4,850 years old, making it one of the oldest known living trees on Earth. The bad environment where it lives actually helps it live longer by slowing its growth and reducing competition from other plants. Its wood is very dense and resinous, which helps it resist rot, insects, and fungi. （它的木材非常致密且富含树脂，这帮助它抵抗腐烂、昆虫和真菌。） Great Basin Bristlecone Pine 2. Project: Make a poster about a plant or an animal  Please guess the animals’ name after reading other description. 4b Snake Plant 虎尾兰 Its name is the ________. It is native to West Africa, but it is now grown indoors in homes and offices all around the world. I chose it because it is extremely easy to care for and is famous for being almost impossible to kill, making it perfect for beginners. Unlike most plants, it releases oxygen and absorbs carbon dioxide at night, which can help improve air quality in bedrooms. It can survive in low light and with very little water. Overwatering is the most common way people harm this tough plant. Snake Plant 3.
