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.

Hanfu fashion has become more and more popular with young people. China has followed Western fashion designs in recent years, but a growing number of young people are now looking to the past for fashion ideas.
If you look closely around your city, you might notice hanfu, the traditional clothing of the Han dynasty. In a recently published report by an online shopping platform, about 2 million hanfu clothes were sold in 2019, nearly 4 times as many as those sold in 2018. Most of the buyers are between 19 and 24 years old.
But why has this traditional clothing become popular with young Chinese people? For some of them, it's a costume for relaxation. Dafan, a 24-year-old college student, told CGTN that dressing in hanfu is a way for her to get away from the troubles of real life. Modern clothing, on the other hand, represents the identity (身份) people need to show every day. "Hanfu and modern clothing help me to show the different sides in me," she explained.
Other teenagers like hanfu because of the culture behind it. They regard it as a way to reconnect with traditions. Its wide sleeves, crossed collars and flowing robes bring people back to ancient times.
"Hanfu is the symbol of the Chinese traditional culture." Nanhe, a 21-year-old costume studio owner, told CGTN.
1.According to the passage, about ________ Hanfu clothes were sold in 2018.
A.2,000,000 B.500,000 C.8,000,000 D.600,000
2.Why does the 24-year-old college student Dafan like to wear Hanfu in her daily life?
A.Because it is very modern to wear Hanfu.
B.Because it is a symbol of Chinese culture.
C.Because it is a good way to relax herself.
D.Because she doesn't want to look different.
3.What does the underlined word "collars" in Paragraph 4 probably mean?
A.A kind of material. B.A kind of colour. C.A part of clothes. D.A part of picture.
A dog was found swimming more than 220 kilometers off the coast of Thailand, and it has been returned safely to land.
Late last week, workers on an oil ______ noticed the animal, all alone, in the water. It began to swim towards the side of the ship. The dog was able to get itself onto a solid area. It looked cold, ______ and scared. It barked at the workers but it was too weak to be heard. The workers lowered a rope around it and worked together to ______ the animal up to safety.
The workers who saved the dog quickly gave their new friend a name: Boonrod. The name means something ______ to "survivor" in the Thai language.
One of those workers was Vitisak. He kept on writing the stories of Boonrod on his home page. He said it was lucky that they noticed the dog in the ______. If there had been waves, he said, the animal likely would not have been seen.
No one knows how Boonrod ended up all alone at sea, or ______ he had been out there. But Vitisak and others have suggested the animal might have fallen ______ a fishing boat.
On Monday, Boonrod arrived at the Songkhla port (码头) in the southern Thai province. A team of animal doctors was waiting for him there. Local people also ______ the dog with neck rubs and a special necklace made of yellow flowers. Many people took pictures with the lucky dog.
Vitisak wrote on his home page, "Today, ship and Boonrod arrived onshore at around 10 a.m. His health ______ has improved. He is getting a bit stronger and can smile."
The dog is now under the care of an animal doctor. On Tuesday, the group published pictures of Boonrod getting washed—______ getting plenty of love and attention.
