【分析】
本题为词语适当形式填空题，需结合固定搭配、词性变化、名词单复数等知识逐一解题：
1. 考查固定搭配decide to do sth，需用动词不定式形式；
2. 需修饰名词garbage bin，应使用smell的形容词形式；
3. 修饰名词pace，用形容词steady的原级即可；
4. manage后接名词，此处指“月收入”，用名词原形；

3. steady pace为固定表达，意为“稳步”，符合语境，故填steady；
4. monthly income意为“月收入”，符合manage（管理）的搭配，故填income；

二、用括号中所给单词的适当形式填空
1. The company's business is growing (steady) this year than last year, bringing more job opportunities.
2. Fireworks (ban) in the city centre to prevent fire accidents every year.
3. The (smell) rubbish in the street made many people feel uncomfortable on hot days.
4. The local government has hired more (guardian) to protect the wild animals in the nature reserve.

1. steadier 2. are banned 3. smelly 4. guardians

【分析】
1. 句中出现than，提示需用形容词的比较级，steady的比较级为steadier；
2. 主语fireworks与动词ban是被动关系，时间状语every year表明用一般现在时，需用一般现在时的被动语态；
3. 此处修饰名词rubbish，需用smell的形容词形式；
4. more后接可数名词复数，guardian需变复数。
【解析】
1. 根据句中than，此处应用形容词steady的比较级，故填steadier；
2. 主语Fireworks与ban是被动关系，时间状语every year用一般现在时，一般现在时被动语态结构为“are + 过去分词”，主语为复数，故填are banned；
3. 修饰名词rubbish需用形容词，smell的形容词是smelly，故填smelly；
4. more后接可数名词复数，guardian的复数为guardians，故填guardians。
【答案】
1. steadier 2. are banned 3. smelly 4. guardians
【知识点】
形容词比较级、被动语态、名词复数

三、任务型阅读
阅读下面材料，从方框中所给的A－E五个选项中选出正确选项（其中一项是多余选项），将其序号填入第1－4小题，并回答第5小题。
If we can get cows to burp(打嗝) less, we may be able to clean up some air pollution. That's the idea behind an Australian climate tech company, Rumin 8. Now it is supported by BEV.
1 But few of us know that farm animals such as cows and goats also create them. They are responsible for a lot of the world's methane(甲烷).
2 It's said that 32 percent of human-caused agriculture（农业）methane comes from farm animals.
BEV is no stranger to climate tech companies, having supported over 100 new businesses. 3 Its boss spends a lot of his money on projects that help the environment.
The latest fight is against farm animals' methane. Rumin 8 has now created a seagrass diet for animals.
4 “The low-cost diet has already been tested. It does a good job in reducing the greenhouse gas,” said BEV. “Our team will support Rumin 8 in working closely with farmers to feed more cows with it all over the world.”
A. This is the most common greenhouse gas after carbon dioxide (CO₂).
B. We all know that cars and factories produce a lot of greenhouse gases.
C. The company says it can reduce methane created in their stomach by 95 percent.
D. The goal is clear—to help build companies that can have an important influence on climate change.
E. BEV hopes to help the new companies to make more money.
5. As a middle school student, what can you do to reduce air pollution?（不超过15词）

1－4. BADC 5. I can go to school by bike instead of by car.（言之有理即可）
