How can batteries help protect our planet? Today, scientists are creating new batteries that are safer, cleaner, and more powerful! Here are two exciting breakthroughs from 2025:

1. Water-Based Batteries: Safe and Eco-Friendly

A new type of battery uses water instead of chemicals inside. Unlike traditional batteries, these water-based batteries never catch fire or explode (爆炸), making them much safer for electric cars and energy storage. Even after 2,000 charges, they still work perfectly! Best of all, they are easy to recycle and cause far less pollution to our soil and water.

2. Recycling Old Batteries

Did you know? Last year, a company called CATL recycled 130,000 tons of old batteries — enough to fill 5,000 school buses! Their “Global Energy Loop” plan turns used batteries into new ones. By 2045, half of all new batteries will be made from recycled materials. This saves precious metals and reduces mining, protecting mountains and forests.

Why This Matters

These innovations help us in two ways: ①Cleaner air: Electric cars with safer batteries mean less smoke from petrol engines. ②Healthier planet: Recycling batteries cuts waste and keeps nature beautiful.

As Dr. Wei Wang, a battery scientist, says: “Green batteries are not just energy — they are hope for our future.”

1.1. What is the main topic of the article?

A Recycling school buses.

B Future electric cars.

C Eco-friendly batteries.

D Water pollution.

解析：选C。C主旨大意题。全文围绕环保电池（eco-friendly batteries）展开。故选C。

2.2. Why are water-based batteries safer?

A They use chemicals.

B They never explode.

C They charge quickly.

D They cost less money.

解析：选B。B 细节理解题。根据第1点中的“never catch fire or explode”可知，这些水基电池永不着火或爆炸。故选B。

3.3. How many old batteries did CATL recycle in 2024?

A 1,300 tons.

B 13,000 tons.

C 130,000 tons.

D 1,300,000 tons.

解析：选C。C 细节理解题。根据第2点中的“a company called CATL recycled 130,000 tons of old batteries”可知，去年，宁德时代公司回收了13万吨旧电池。故选C。

4.4. The underlined word “innovations” means ______.

A old methods

B new ideas

C large factories

D dangerous tests

解析：选B。B 词义猜测题。根据上下文可知，innovations指代“水基电池”和“回收旧电池计划”等新事物和创新举措。故选B。

5.5. What can we infer from Dr. Wei Wang’s words?

A Batteries are useless.

B Water batteries fail often.

C Recycling is too expensive.

D Green energy brings hope.

解析：选D。D 推理判断题。引语“Green batteries are not just energy — they are hope for our future.”绿色电池不仅仅是能源——它们是我们未来的希望，由此可知，环保能源为人类的未来带来希望。故选D。
