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 ricks.

A. give an example B. show the main idea of the passage

Alexa is a form of artificial intelligence, or AI for short. Many people start their mornings by asking Alexa for the weather forecast or the latest news. A device(设备) that houses Alexa can also play music from your favorite playlists, keep a shopping list, order takeout food, answer questions, send messages and even run “smart” home controls.
Training AI systems to respond to problems with human-like intelligence and learn from their mistakes can take months, or even years. Consider Alexa and similar software, such as Apple’s Siri. To do the tasks its human owners ask, these systems must make sense of and then respond to sentences such as, “Alexa, play my Ed Sheeran playlist” or “Siri, what is the capital of India?”
Computers can’ t understand language as it is spoken by people. So AI researchers must find a way to help humans communicate with computers. The technology used to get computers to “understand” human speech or text is known as natural language processing. By natural language, computer scientists refer to the way people naturally talk or write. To teach an AI system a task like comprehending(理解) a sentence or responding to a person ’s last move in a board game, scientists need to feed it lots of examples.
AlphaGo is an AI system designed by Google that has beaten a human champion, Lee Sedol, at the strategy(策略) board game Go. To train AlphaGo, Google had to show it 30 million Go moves that people had made while playing the game. Then AlphaGo used what it learned to analyze those plays as it played against different versions (版本) of itself. During this practice, the program came up with new moves---ones never seen in games between people.
1.What does the example of Alexa show?
A. AI may replace humans one day. B. AI is playing a role in our modern life.
C. AI has been widely used around the world. D. AI has totally changed people’s bad habits.
2.How do scientists train AI systems?
A. By testing them thousands of times. B. By teaching them almost everything.
C. By giving them quite a lot of tasks to do. D. By providing them with large amounts of data.
3.What can we learn about AlphaGo?
A. It has become very skillful and intelligent B. It is the most convenient AI system.
C. It avoids making any mistakes D. It just follows human orders
