The environment in my city is becoming worse and worse. Factories burn things to make energy.
1. (人们砍倒了许多树). It is bad for the air too.
2. (街上有很多汽车). It also pollutes the air. People throw away rubbish everywhere. This pollutes the land. Human beings discharge polluted water into rivers, resulting in the death of animals in the water. As far as we know, it is our common dream to build a green home.
3. (人们可以做些什么来保护地球)? 4. (首先,我们应该种树使空气清洁). Second, we must stop throwing away so much rubbish. 5. (我们应该乘公共汽车或骑自行车去上学或上班). All in all, we must try to make the world more beautiful.
Let's work together to protect our city and bring back the clear blue sky.

【分析】本题为根据中文提示补全英语句子的书面表达题，解题思路是结合上下文语境，将中文提示准确转化为符合英语语法、时态和固定搭配的句子，注意常用句式（如there be、特殊疑问句）、短语（如cut down、by bus）以及不定式作目的状语的用法，确保句子通顺且符合原文语境。
【解析】1. 中文提示“人们砍倒了许多树”，用一般现在时，“砍倒”是固定短语cut down，主语为people，故译为People cut down many trees；2. 中文提示“街上有很多汽车”，用there be句型，主语many cars为复数，be动词用are，“街上”是in the streets，故译为There are many cars in the streets；3. 中文提示“人们可以做些什么来保护地球”，为特殊疑问句，用what引导，“做什么”是do，“保护地球”用不定式表目的to protect the Earth，故译为What can people do to protect the Earth；4. 中文提示“首先，我们应该种树使空气清洁”，“首先”是First，“应该”是should，“种树”是plant trees，“使空气清洁”用不定式表目的to make the air clean，故译为First, we should plant trees to make the air clean；5. 中文提示“我们应该乘公共汽车或骑自行车去上学或上班”，“乘公共汽车”是by bus，“骑自行车”是by bike，“去上学或上班”是go to school or work，用or连接方式，故译为We should go to school or work by bus or by bike。
