Smoking is harmful. But as soon as you quit the habit, everything will be OK, right?
Wrong
New research has found that even if you give up smoking, the damage it has done to your genes(基因) will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed—a number that is one-third of known human genes.
According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.
When you stop smoking, a lot of these genes will return to normal within five years.
This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years. It’s almost like leaving a footprint on wet cement (水泥)—it will always be there, even when you’ve walked away and when the cement becomes dry.
Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

It’s hard to be a bird in a world which is in the charge of mankind.
You can hardly hear yourself sing, let alone hear the songs of your friends… and worst of all, you can’t hear a predator(捕食者). Noise is almost everywhere, especially noise from traffic.
Researchers have tried to study the influence of road noise on animals by looking at animals living near noisy roads.
“We figured out a way to have just the noise without any of the other effects of the road, and to do that we put many speakers in a forest where there was no road,” said Chris McClure, a biologist at Boise State University and The Peregrine Fund. He and his team carried out their experiment at a place popular with birds in Idaho as they fly south for the winter.
While the noise kept lots of birds away, some remained. But they had trouble putting on enough weight to support them in the next part of their migratory journey.
“They have to take food but they also have to avoid getting eaten by a predator. But these two things can’t be done at the same time because to eat, they have to look down, which means they aren’t looking at predators.”
And when it’s too loud, they can’t hear the alarm calls of other birds. So they have to waste time looking for predators instead of searching for food.
By 2050, it’s thought that enough new roads will be built to circle the planet more than 600 times. But there’s an easy solution to the noise problem—“Lowering speed limits does a lot.”
So next time you’re driving through nature, just slow down a little. It’s safer for you and the wildlife. And you can enjoy the view a little longer.
1.Who does the word “you” in Para 2 refer to?
A.A driver. B.A predator. C.A researcher. D.A bird.
2.Why did the researchers do the experiment in a forest without roads?
A.To prevent birds from being hit by cars.
B.To separate noise from other effects of the road.
C.To test a larger number of birds.
D.To put as many speakers as possible.
3.Why can’t birds put on enough weight with much noise around?
A.They can’t concentrate on looking for food.
B.They have to fly south for the winter.
C.They can’t hear the alarm calls.
D.They feel afraid of the noise.
4.What is advised to do to protect birds from the noise problem?
A.To build enough new roads.
B.To carry out more experiments.
C.To enjoy the view a little longer.
D.To drive slowly through nature.
