Our school is going to have an Environment Week next month. Many activities 1 (hold) to encourage students to protect the planet. First, we will design 2 (海报) to raise more people's awareness. Some students will also give speeches about the lakes and rivers which are seriously 3 (pollute). We care about other pollution problems too, like air pollution. We know harmful 4 (气体) from cars make the air unclean and can even cause 5 (咳嗽). For those problems, we will come up with ideas to deal with them and vote 6 the best "Green Idea". We hope our actions can really make a difference!

三、阅读与回答问题
Anna Du was walking along the beach when she noticed plastic there. She reached down to pick them up and quickly realized there were many more pieces than she
could deal with.
Du, 12 years old at the time, tried to solve the problem like any good scientist—first, by doing a little research. That's how she learnt that 8 million tons of plastic end up in the oceans every year. Then she got to work building something that could help solve the problem: a robot that uses infrared light (红外线) to find plastic. Her robot can move through water and find plastic on the ocean floor.
Du started attending lectures and workshops at a university when she was five years old, so she learned the necessary engineering skills to build her robot. She said getting her robot to move through water well was not easy. She failed many times, but she never gave up trying and testing.
When asked about future plans, she said she wanted to deal with the effects of climate change. "I think there are a lot of problems that could be solved with new inventions," said Du.
In addition to her amazing robot, Du also wrote a book called *Microplastics* (微塑料) *and Me* to introduce the harm of microplastic. She said, "I encourage my fellow students to visit local libraries, universities, environmental and other organizations to find out about the pollution issues facing your own community."
