答案： threw; made; put; from; plant

There were a lot of factories in the city many years ago. We could often see the black smoke out of the chimney(烟囱). It made the air very dirty. Some people fell ill. They needed to see the doctor. People couldn't walk in the streets in the early morning, or they would get a bad cough. Then people moved them away from the city. We also planted more trees to keep the air clean.
