Look at the pictures and talk about what you know about rainforests and deserts. 结对谈论雨林与沙漠的已知信息。 【提示框】 猜谜就用上节课三句式：气候 It is hot and wet...＋动植物 It is home to...——带着已知读文本，效率翻倍。 （二）读中理解 · 略读定主旨与划主题句 Skim the text, and then think about what's the main idea of the text. 略读选择主旨：Rainforests and deserts are two different living places in nature.（学习策略：Skim means reading a passage rapidly to grasp its main idea without focusing on every single word. 略读指快速阅读抓住主旨，不逐字阅读。） Underline the topic sentence, and then write a proper title for the text. 划出主题句并为文本拟标题：主题句 Rainforests and deserts are two very different living places in nature.（首段），标题 Rainforests and Deserts。 【知识点】 ▶略读策略：快速通读全文抓住主旨大意，不逐词阅读；主旨常在首段主题句或尾段总结句中——本文首段即主题句，尾段 wonders of nature 点题升华； ▶拟标题要覆盖全文对比对象：标题 Rainforests and Deserts 同时涵盖两个主体，且用 and 连接体现「对比」关系。 【提示框】 划主题句先看首句——说明文第一句常直接点明「谁和谁+什么关系」；拟标题别写成单方（只写 Rainforests✘）。 略读定主旨页 （三）读中理解 · 猜词义与填表格 Activity 2 Read the text and guess the meaning of the underlined words. 结合上下文猜划线词义：plenty（大量——animals have plenty of food to eat）、cactuses /ˈkæktəsɪz/（仙人掌——These plants can keep water.）。 Activity 3 Read the text again and complete the table. 再读文本完成表格：living places／plants／animals／wonders／home 五个关键词回文定位。 【提示框】 猜词两条路：看前后句逻辑（plenty of food 前面说 plants grow very tall、动物不愁吃→「大量」）；看例子与功能（cactuses 后接 These plants can keep water→会储水的植物=仙人掌）。 猜词：plenty—大量；cactuses—仙人掌（复数）。 划主题句拟标题页 （四）读中理解 · 完成对比图表 Activity 4 Complete the comparison and contrast chart according to the text. 依据文本完成雨林与沙漠的对比图表：Rainforests—Climate: warm and wet；Plants: many kinds, grow very tall；Animals: many kinds, with plenty of food。Deserts—Climate: hot and dry；Plants: some kinds of plants（like cactuses, keep water）；Animals: only a few kinds, live on other small animals。共同点：Rainforests and deserts are two very different living places in nature.（动物和植物能共同栖息 Animal and plants can live together）。 【提示框】 对比图表左右分栏填：先气候（warm wet vs hot dry），再植物（very tall vs cactuses），最后动物（plenty of food vs live on other small animals）——逐行对照，别串行。 雨林：warm／wet；many kinds of plants, grow very tall；plenty of food。沙漠：hot／dry；some kinds of plants；other small animals。 雨林沙漠对比图表页 （五）读后输出 · 短语运用与复述 【过渡语】文本读透了，把四个关键短语用起来。 Activity 5 Fill in the blanks with the phrases in the box. 选短语填空：plenty of／many kinds of／live on／be home to。 Match the sentences with the pictures. 把四句与图片匹配（2／4／1／3）。 Retell the passage with the help of the table. 借助表格关键词（living places／plants／animals／wonders／home）复述全文。 【知识点】 ▶live on 意为「以……为食；靠……生存」：Horses live on grass.／Most desert animals live on other small animals.； ▶be home to 主语是场所（The sea is home to different kinds of fish.）；many kinds of＋可数名词复数（many kinds of flowers）；plenty of＋可数复数或不可数名词均可。 1. live on　2. many kinds of　3. is home to　4. plenty of。 Activity 5 选词填空：1. Horses ____________ grass and they drink water.　2. There are _____________ flowers in my garden.　3. The sea ____________ different kinds of fish.　4. There is ______________ food for animals in the rainforest. 短语选词填空页 （六）语言点讲解 · plenty of 【过渡语】文本里 animals have plenty of food 的 plenty of 是本课语言点头号。 学习语言点：Plants can grow very tall, and animals have plenty of food to eat. 植物能长得很高，动物也有很多食物吃。 【知识点】 ▶plenty of 修饰可数名词复数或不可数名词，相当于 a lot of/lots of；无「a plenty of」这种表达——这是常见错误搭配，正确形式仅为 plenty of； ▶主谓一致：修饰可数名词复数时，谓语动词用复数；修饰不可数名词时，谓语动词用单数：The garden gets plenty of sunlight, so the flowers grow well.／He has plenty of friends. His friends can help him with the move. 【提示框】 千万别写 a plenty of——plenty of 前面不加 a；判断谓语单复数看 of 后面的名词，不看 plenty。 plenty of 讲解页 （七）语言点讲解 · fish 的三种用法 学习语言点：The sea is home to different kinds of fish. 海洋是各种鱼类的家园。 【知识点】 ▶fish 作可数名词表「鱼的条数」时，单复数同形：There are three fish in the bowl.； ▶fish 作可数名词表「鱼的种类」时，复数形式为 fishes：There are many kinds of fishes in the river.； ▶fish 作不可数名词表「鱼肉」：I like eating fish.／We often go fishing on weekends.（go fishing 去钓鱼）。 【提示框】 fish 三张脸：几条鱼用 fish（单复同形）、几种鱼用 fishes、鱼肉还是 fish——前面有 kinds of 时复数用 fishes。 （八）随堂检测 单项选择：1—4 D C B A；完成句子：1. are home to　2.
