dangerous 形容词,表“危险的”,描述人/物具有危险性,作定语/表语 a dangerous animal, be dangerous It’s a dangerous animal. Don’t get close to it.(它是一种危险的动物,不要靠近。)

五、重点语法
被动语态(一般现在时/一般过去时/一般将来时)
本单元核心语法,聚焦被动语态的基本结构与运用,贴合“濒危动物被猎杀、栖息地被破坏”的单元话题,侧重动作的承受者作主语。
1. 被动语态的核心概念
- 主动语态:主语是动作的发出者(如:People kill many animals.)
- 被动语态:主语是动作的承受者(如:Many animals are killed by people.)
- 基本结构:be + 动词的过去分词(be动词随时态、人称变化,过去分词为固定形式)
2. 三种基础时态的被动语态(教材核心考点)
时态 被动结构 否定式 一般疑问句 教材话题例句
一般现在时 am/is/are + 过去分词 am/is/are + not + 过去分词 Am/Is/Are + 主语 + 过去分词? Elephants are killed for their ivory every year.(大象每年因象牙被猎杀。)
一般过去时 was/were + 过去分词 was/were + not + 过去分词 Was/Were + 主语 + 过去分词? Many forests were destroyed last year.(去年许多森林被破坏了。)
一般将来时 will be + 过去分词 / be going to be + 过去分词 will not be + 过去分词 Will + 主语 + be + 过去分词? More laws will be made to protect wild animals.(将会制定更多法律来保护野生动物。)
3. 核心注意事项
1. 被动语态中,动作的发出者可由by 引出,若发出者不明确/不重要,可省略by短语(本单元高频用法)。
例:Many animals are killed (by people) for their fur.(许多动物因皮毛被猎杀。)
2. 熟记常见不规则动词的过去分词(本单元高频):save-saved, kill-killed, destroy-destroyed, make-made, do-done, take-taken。
3. 被动语态的主语为复数时,be动词用are/were/will be,与名词单复数保持一致。
例:The habitats are destroyed.(栖息地被破坏了。)
4. 即时练(教材语境)
将下列句子改为被动语态:
1. People cut down many trees in the forest.
2. We will save more endangered animals.
3. Hunters killed a lot of tigers last year.
(答案:1. Many trees are cut down in the forest. 2. More endangered animals will be saved. 3. A lot of tigers were killed by hunters last year.)
六、写作指导(动物保护倡议/介绍濒危动物类短文)
1. 核心写作结构(贴合单元写作任务:写一封动物保护倡议书或介绍一种濒危动物)
部分 内容要点 单元常用表达
开头 引出话题,点明濒危动物的现状/介绍具体濒危动物,说明写作目的 Many wild animals are in danger now and some even face the danger of dying out. Today I want to talk about pandas, one of the most precious endangered animals in China. / It’s time for us to take action to save the endangered animals.

2. 范文示例
Let’s Save the Endangered Animals
Animals are our best friends and an important part of the natural world. But now many wild animals are in great danger. Some of them are dying out because of human activities, and it’s time for us to take action to save them.
Why are so many animals in danger First, people cut down a lot of trees every year, so many animals lose their habitats and can’t live in the wild any more. Second, some greedy people hunt animals for their fur, ivory and bones. Third, water and air pollution makes the animals’ living environment worse and worse. Every day, many animals are killed by humans, and if we don’t stop this, more animals will disappear forever.
Protecting animals is not only necessary but also our duty. What can we do For us students, we can tell our family and friends about the importance of protecting animals. We can also plant more trees and never buy ivory products. The government can make more strict laws to stop hunting. If everyone works together, we can give the animals a safe home.
Animals and humans live in the same world. Saving animals is saving ourselves. Let’s start from small things and work together to protect the endangered animals. I believe the world will be more beautiful with all kinds of animals living in it.
