Unit 8 A green world 语法+写作解析
一、语法解析
被动语态(二)
1.一般将来时：主语+will be+动词过去分词
Eg: The room will be cleaned tomorrow.
明天房子被打扫。
2.现在进行时：主语+am/is/are+being+动词过去分词
Eg: The room is being cleaned now.
房子现在被打扫。
3.过去进行时：主语+was/were being+动词过去分词
Eg: The room was being cleaned when I came in.
当我进来的时候房子正在被打扫。
4.现在完成时：主语+have/has been+动词过去分词
Eg: The room has already been cleaned.
房子已经被打扫完了。
5."主语+谓语+宾语+宾语补足语"句式的被动语态
这种类型的句子变为被动语态时，通常将主动句中的宾语变为被动句的主语，谓语动词变为被动结构，宾语补足语不发生变化，但相应地成为主语补足语。宾语补足语如果为不带to的不定式，句子变为被动语态时要加上to(谓语动词为let时除外)
Eg: The teacher asked us to finish the homework before Friday.
老师要求我们在周五之前完成作业。
-- We were asked to finish the homework before Friday by the teacher.
我们被老师要求在周五之前完成作业。
We were made to clean the classroom by the teacher.

Hi,guys,
Isn't it pleasant to study in an environmentally friendly school To develop a green lifestyle, we students can go green at school in smaller ways.
We can do simple things to help save resources. First of all, we should save as much paper pas possible. It's necessary to reuse the textbooks and use both sides of the paper. Second, it's a good idea to save water. We should drink up all the water in each bottle. Let's not keep water running when we don't use it. What's more, don't forget to turn off the lights when we leave the classrooms to save electricity.
Besides, we should try our best to reduce pollution at school. It's important for us to take care of the trees and flowers. We should walk or ride o and from school if possible. Many hands make light work.
Boys and girls, let's put these ideas into action from now on. I'm sure our school will be more beautiful.
That's all. Thank you!
