New research suggests that growing trees and other plants near factories could reduce pollution by almost one- third.

More plant life may even cost less and be more effective (有效的) than technology designed to cut pollution, a new study found. Researchers collected data about air pollution and plant life in 48 cities. They studied public records from every city.

The researchers knew that trees and plants are taking in large amounts of harmful air. So they tried to find out whether new plants could reduce air pollution.

The study tried to show how this vegetation (植被) could reduce the pollution, including the production of energy from coal, oil and gas. The researchers found that growing plants, where possible, could cut air pollution by about 27 percent in the areas studied. They also found that in 75 percent of the areas, it would cost less to use plants and trees to reduce air pollution than to add new air cleaning technology.

"The fact is that traditionally, especially as engineers, we don't think about nature," Dr. Bakshi, said. "We just focus on putting technology into everything."

"To solve air pollution problems, people need to start learning from the nature and respecting it," Bakshi said. He added that nature-based methods could result in "win-win" solutions that save money and are better for the environment.

The study couldn't tell which kinds of trees or plants would be best at reducing air pollution. But Bakshi said they might make a difference in air quality, so further study is needed.

The researchers said that more trees and plants could help lower air pollution levels in both cities and rural areas. However, success rates (比率) would be different depending on how much land can be used and its air quality levels.

A.1/3 of the pollution can be reduced by technology.

C.Plants improve the air quality in cities and the country.

D.Air quality levels mainly decide the success rates.

I've never thought that a money raiser could have had such a huge influence on my life. Back in 5th grade, our school announced a money raiser and each class would get a box to fill it up with small _______. To make my class to come to the first place in the money raiser, I took two fifty-dollar bills _______ to school and put them into the box.

Two weeks later, my parents asked me about the money. They said they had discovered the truth and weren’t _______, but I must do something to make up for it.

My dad had the perfect idea in mind. The day _______ Christmas, he took me to St. John's Hospice in north Philadelphia, and explained to me that we were going to be working in the kitchen for several hours, making meals with potatoes and chicken for the 300-400 _______ men that came in each day.

As the lunch began. I thought I could wait for this by playing with my new toys. But as the mealtime went on. I found these men were overjoyed at the _______ food they were receiving, which I couldn't believe. I considered it a fairly common winter meal. The men's faces lit up with the food they were given. I realized how poor some people in this world actually are.

I had always heard about giving to the poor; but I never fully _______ it until that day. It was enlightening to see how thankful they were for something I thought was _______. I learned that I didn't really need all the good and expensive things I hoped for. On the drive home, my dad _______ McDonald's for lunch and I answered no at once. I knew that I didn't need it.

That day I came to know how good the feeling is to help people who are really in need. I now return to St John’s Hospice every year, trying to make a ________. This is why I am becoming a doctor, thinking that in the future I will change people's lives in a way just like my father did on that December 26th.
