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 (»ùÒò) 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 (ÖÎÓú) 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 (Ë®Äà) Ò»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.

The ancient Chinese game Go is considered one of the most complicated strategy games. Winning the game was seen as a test of human creativity. That is, until a machine found a way to do it better. Alpha Go, an artificial intelligence (AI) machine built by Google, won its first match against South Korean Lee Sedol on March 9. Still digesting his loss, Lee said during the post-game press conference, ¡°1.¡±

But that was just the beginning. In the following week, Alpha Go outperformed Lee in another three matches. 2.

Some people have been arguing that AI is harmful to the human race. 3. Similarly, UK scientist Stephen Hawking once warned that the ¡°development of full artificial intelligence could spell the end of the human race¡±.

So are we really on the verge(±ßÔµ)of living in the world shown in the Terminator(ÖÕ½áÕß)sci-fimovies? ¡°Not quite,¡± answered The Economist. After all, it¡¯s hard to get computers to apply their knowledge to everyday situations. ¡°4.¡± Thomas Johnson said, founder of an AI toy company. ¡°But for a robot, to walk up and down hills requires so many complicated decisions to be made in real time, and it¡¯s really difficult to do.¡±

As The Economist put it: ¡°We have a long way to go before AI¡¯s abilities truly begin to approach the human brain, despite how powerful the technology can be when focusing on a single task.¡±

Meanwhile, John Mark off of The New York Times argued that researchers should build artificial intelligence that aims for ¡°intelligence augmentation (Ôö¼Ó)¡± (IA) in which computers make people more effective.

He wrote: ¡°5.Since technology depends on the values of its creators, we can make choices using technology to improve the world.¡±

A. Many robots fell over like little kids learning to walk.

B. We take for granted things like balance and vision.

C. Eventually, our fate is in our own hands.

D. So what is next for AI and humanity?

E. That made the five-match score 4-1 in favor of Alpha Go.

F. In 2014, US businessman Elon Musk said at an MIT conference that developing the technology is calling up a ¡°demon(ħ¹í)¡±.

G. I am in shock; I admit that.

Nowadays more and more children now chat daily either online or through their mobile phones. 1.Some are shy ¡°in real life¡± but are confident to communicate with others online; others find support from people of their own age on relationship issues, or problems at home.

Sometimes the online world, just like the real world, can introduce problems, such as bullying or arguments.2. But there are also a few people who use the Internet for offensive (ð·¸ÐÔµÄ) or illegal aims. Children must be made aware of both the good things and the dangers.

3.Just as you decide which TV programs are suitable, you need to do the same for the websites and chat rooms your children visit. Remind your children that online friends are still strangers. Reminding them of the risks will keep them alert (¾¯Ìè).

4.So it¡¯s likely that your children may know more than you do. We get left behind when it comes to the latest gad-gets and the interactive areas of websites, like chat rooms and message boards, which are especially strange. 5.Chatters love to use abbreviations (Ëõд) such as: atb ¡ª all the best, bbfn ¡ª bye bye for now, gr8 ¡ª great, Idk ¡ª I don¡¯t know, kit ¡ª keep in touch, paw ¡ª parents are watching, lol ¡ª laugh out loud. It seems like another language, and it is!

A. Going online is great fun.

B. Computer studies are part of schoolwork now.

C. The language of chat is strange to many parents, too.

D. There are some websites that are not suitable for children.

E. To keep children safe, your management must cover the family computer.

F. They are connecting to a huge number of other children all over the world.

G. Surfing the Internet takes too much of the time that should be spent on lessons.

When we know somewhere well£¬we say we ¡°know it like the back of our hand¡±. But new research has shown that we don¡¯t actually know as much about our hands as we think we do.

Wider and shorter

Professor Matthew Longo at the University of London and his team did an experiment, covering the left hands of 100 people. Then they asked the people to point to where they thought their fingertips and knuckles (Ö¸¹Ø½Ú) were. They made some quite big mistakes.

¡°People think their hand is wider than it actually is,¡± said Longo. The fingers also seem shorter than they are. This mistake gets worse as you go across the hand from the thumb to the little finger.

Sense of position

¡°It is connected to our sense of position,¡± explained Longo. This is our ability to tell where different parts of our bodies are, even when we can¡¯t see them. ¡°It tells us whether a joint is straight, or not¡± he said. It also tells us whether we are going up or down in an elevator. All this information comes from signs from nerves in real time. It¡¯s like our brain has maps ¡ª maps that show the size and shape of our body. ¡°This experiment tried to find those maps,¡± said Longo.

Strength(Ç¿¶È) of feeling

But these maps make mistakes. These mistakes may be made because of how the brain understands different parts of the skin. ¡°Our brains ¡®see¡¯ areas as larger where the skin feels touch strongly,¡± said Longo. Body parts don¡¯t appear as their true size, but appear bigger or smaller depending on how strongly they feel touch. Our lips, for example, have more nerves than our nose. So brain ¡°sees¡± lips on its map of the body as being bigger than our nose. The same thing happens for other parts of the body that have lots of nerves.

Longo believes that more research in this area may help us to understand eating problem better, because people suffering from these problems may not know their bodies properly.

1.Which of following statement is TRUE about the experiment according to the article?

A. People think their body parts are larger than they actually are.

B. People made more mistakes about their little fingers length than their thumbs¡¯ length.

C. People¡¯s fingers are actually shorter than they think.

D. People were asked to draw their hands from memory

2.What does the underlined ¡°it¡± in Paragraph 4 refer to?

A. The new experiment. B. The location information.

C. The mistake people made. D. The sizes of fingers and hands.

3.We can learn from the article that ________.

A. the maps of people¡¯s bodies form before they are born

B. the maps of our body are based on information from nerves

C. our sense of position tells how different parts of the body work

D. how we feel about our body shape is only decided by our sense of position

4.We can infer from the article that ________.

A. the hand feels touch more strongly than fingers do

B. our lips have a weaker sense of touch than our nose

C. there are more nerves in the finger than in the hand

D. our sense of position should not be trusted because it is too often incorrect

JOHANNESBURG¡ªThey say cats have nine lives. Now a Chinese toad(ó¸òÜ) has joined that club of clever survivors.

South Africans are shocked at the endurance of a toad that got trapped in a cargo shipment from China to Cape Town, after jumping into a porcelain(´ÉÆ÷) candlestick£¨Öǫ̀£© that was made there. South African officials reportedly planned to put down the creature, fearing it would cause harm as an invasive species if it were let go in the wild.

But the toad got a last-minute pardon. Mango Airlines, a South African airline, transported the toad on Friday to Johannesburg for delivery to an animal shelter, after officials decided to find a way to let the toad live. The two-hour fight was a breeze compared to the trip from China, a long way of many weeks and thousands of kilometers across the Indian Ocean.

Airline spokesman Hein Kaiser said the toad got ¡°first-class treatment¡±, sitting in a transparent plastic container with escort Brett Glasby, an animal welfare inspector. There was even a ceremony, in which the toad¡¯s boarding pass was handed to Glasby.

¡°He was the star of the show on the flight,¡± Kaiser said of the amphibious(Á½ÆܵÄ) passenger. ¡°I think every passenger stopped to have a look.¡±

On landing in Johannesburg, the toad was brought out of its container for a celebrity-style photo shoot. Observers said the brown toad seemed like a cool customer. It belongs to the Asian Toad species, which breeds during the monsoon(¼¾·ç) season. It is believed to have survived the trip from China by hardening its skin to prevent it from drying out, and also by slowing its breathing and heart rate¡ªmethods that help the species survive in times of drought.

¡°We¡¯ve had snakes in imported timber and scorpions(Ы×Ó) in fruit. We were called because the toad was right inside the candlestick, and we had to break it to get it out¡± Glasby, the inspector, told The Star, a South African newspaper.

1.What is the passage mainly about

A. An Asian toad gets a new home in South Africa.

B. Asian toads can¡¯t get used to the life in South Africa.

C. Workers shipped a toad to South Africa on purpose.

D. South Africa ignores the protection of animals.

2.What would/might happen if the toad were released into the wild?

A. It would make the locals feel shocked

B. It might harm the native species

C. It would lose its life in the wild

D. It might flee into another country

3.Why was the toad able to arrive in South Africa alive?

A. Because it escaped all attacks and hunts

B. Because it used to stop its breath in winter

C. Because it formed hard skin to protect itself

D. Because it was lucky to be given a chance

4.What can be inferred from the passage?

A. Sometimes animal are transported accidentally

B. No one has seen such a big toad in Africa

C. A candlestick is the best place for a toad

D. Droughts make toads live longer.
