Ⅳ. Read and answer the questions.
Across the world, humans buy around 1.3 billion plastic bottles a day.
However, only about 9% of them are recycled and most of them end up in the land, the ocean or elsewhere in nature.
When beach-loving Madison Checketts noticed that many plastic bottles polluted the sand during her family trip to California, the 12-year-old American girl realised that this needed to be changed. So for her school science project, she decided to work on reducing plastic waste.
During her research, Madison came across a special method of packing water within a material that people could eat—a gel(凝胶) bag. At that time, the girl got her idea: She would design an edible(可食用) water bottle.
To carry out her idea, Madison did tests with common food additives(添加剂). She also learnt from earlier research on edible water bottles. She found that water and lemon juice could make a gel bag stronger. And she made her bottles bigger and able to last for a longer time. She called it the Eco-Hero.
“My biggest goal with this project is to help the world,” says the young inventor. She hopes her invention can encourage others to take better care of the earth. “It doesn’t necessarily have to be in a big way,” she adds. “People can make a difference in the world, even if it’s just in a small way.”

()1. What did Madison do to improve the edible water bottle?
A. She used different kinds of water.
B. She learnt from earlier research.
C. She changed the colour of the bottle.
D. She added some apple juice to the bag.
()2. What does the underlined sentence mean in Paragraph 5?
A. Big projects are necessary to protect the earth.
B. Madison’s invention makes a great difference.
C. It is too difficult for Madison to achieve her goal.
D. People can protect the earth through small actions.
3. What is Madison’s biggest goal with her invention?

4. As a student, what can you do in your daily life to take care of the earth?

1. B
2. D
3. Madison’s biggest goal with her invention is to help the world.
4. One possible version: As a student, I can pick up litter in the park and put it into the right bins. Also, I’ll turn off lights when leaving rooms to save electricity.

这是一篇围绕减少塑料污染的英语阅读理解题，包含细节理解、句意猜测、信息查找和开放类题型。解题思路：1. 第1题是细节理解题，需定位原文中Madison改进可食用水瓶的相关描述，匹配对应选项；2. 第2题是句意猜测题，结合划线句的上下文语境，重点关注后文解释内容理解句子含义；3. 第3题是信息查找题，直接定位原文中关于Madison最大目标的句子提取答案；4. 第4题是开放类题型，结合学生日常实际，围绕爱护地球的行为给出合理回答。

2. 第2题：划线句后文解释“People can make a difference in the world, even if it’s just in a small way.”，意思是人们即使通过小事也能对世界产生影响，对应选项D。A选项“保护地球需要大项目”与原文意思相反，B选项“Madison的发明有很大影响”不是划线句的含义，C选项“Madison实现目标太难”不符合语境，故答案为D。
3. 第3题：根据原文第五段“My biggest goal with this project is to help the world.”，直接提取答案为Madison’s biggest goal with her invention is to help the world.
