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.

1.The researchers found that plants were ________ air cleaning technology.

A.better than B.worse than C.as cheap as D.as good as

2.Most engineers think ________ is more important in reducing air pollution.

A.nature B.cost C.location D.technology

3.What do "win-win" solutions refer to in Paragraph 6?

A.Building more factories to develop technology.

B.Reducing air pollution with less money.

C.Saving more money by developing technology.

D.Developing technology and reducing pollution.

4.What can we learn from the passage?

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

B.The study has found out the most effective plants.

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

D.Air quality levels mainly decide the success rates.

Alexis Lewis is a teenager from the USA. She likes to invent—to think of new ideas for things that no one has made before, and then make them.

Alexis often enters competitions for young inventors. When she was younger she spent time with her grandfather, who made transport for people to go to space. One day Alexis’ mother told her about a newspaper article which explained how difficult it was to get sick people through the countryside to hospital in Africa. Alexis wanted to help.

Alexis knew that in North America, before there were cars, horses pulled heavy things on a travois(旧式雪橇) made of wood. Alexis thought people could do the same, but she added wheels. To make her travois light, she used bamboo, a plant which grows in Africa, not wood.

To pull Alexis' travois, you wear a belt, which means you can carry or hold other things. Alexis thinks her travois might be useful for carrying food home from the market, as well as taking people to hospital. Now it's finished, she's writing instructions for building one so people in Africa can make it themselves.

With help from US companies, Alexis plans to give ten travois free to hospitals in Africa. She doesn't want money for them because they are for poor people.

Alexis doesn't know if she wants to be an inventor when she's older, because she also likes music and writing, but she thinks it's important for children to learn about inventing at school.

1.Why did Alexis decide to invent a new type of transport?

A.Because she wanted to win a competition.

B.Because her mother told her about a problem.

C.Because her grandfather worked on spaceships.

2.How is Alexis' travois different from those pulled by horses?

A.It's heavier. B.It is made of wood, C.It has wheels.

3.What does the author say about using Alexis' travois ?

A.People will need instructions to use it.

B.People should not use it to carry shopping,

C.People can pull it by wearing a belt.

A.US companies. B.Ten travois. C.Poor people.

The idea for the book Harry Potter and the philosopher’s Stone came to Joanne Kathleen Rowling in 1990. It took her seven years to finish writing it. During those seven years she had a number of jobs, including one job as an English teacher in Portugal.

Rowling sent the book to four publishers before one of them bought it. She was very happy to sell her book because it was her life’s dream to be a published writer.

Without question, Rowling’s life had completely changed, in just three years.

Harry Potter has now sold more than 30 million books around the world and has been translated into more than thirty-five languages. In 1997, she earned £70 (about US$110) a week.
