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.

The days of glancing at a map or the screen of your smart phone when you’re lost will soon be over, thanks to new shoes that tell you which way to turn to. The shoes use a Bluetooth link to communicate with your mobile’s mapping system. The mobile works out which route you should be following and the shoes then produce a slight shaking in either foot telling you when and where to change direction.
The shoes will also count the number of steps you’ve taken and the calories you’ve burned, and they’ll even buzz to warn you you’ve left your phone behind, or to tell you when you’re travelling past an interesting landmark.
“They are as easy to use as a tap on the shoulder,” said Krispian Lawrence, 30, who developed the shoes with partner Anirudh Sharma, 28, in Hyderabad, India. “You can even communicate with them using hand gestures and finger snaps because the shoes have sensors that can pick up movement and sound.”
The Lechal shoes go on sale worldwide in June but Lawrence and Sharma’s company, Ducere Technologies, has already taken more than 3,000 pre-orders. Lawrence believes the shoes will also improve road safety. “If I’m on my bike or motorbike, I don’t want to stare at my phone ---it’s dangerous,” he says. “I’d rather be guided by my footwear.” He believes his invention will prove invaluable for the visually impaired and has promised that every mainstream pair sold by Ducere will subsidize(資助) a cheaper pair for a visually damaged person.
Footnav technology does not impress explorer Sir Ranulph Fiennes, however. “What’s wrong with a good old-fashioned map?” said the 70-year-old when told of the shoes. “If you rely too heavily on technology, you’re heading for trouble. Too many people have forgotten the basics: how to read a map and a compass.”
1.According to the passage, which of the following can smart shoes NOT do?
A. Guiding your road.
B. Warning of the loss of your wallet.
C. Counting your steps and calories.
D. Reminding you of landmarks.
2.Smart shoes can be used as a map mainly because .
A. they can talk to people
B. they can produce a slight shaking
C. they are guided by a remote control
D. they are linked to mobiles’ mapping system
3.What’s the possible meaning of the underlined word “impaired”?
A. Discouraged. B. Disabled.
C. Disappointed. D. Disliked.
4.What is Sir Ranulph’s attitude towards this invention?
A. Positive B. Negative.
C. Disturbing. D. Confused.

I’ve been really lucky this year. Not only did I have the opportunity to live in France, but I was able to see some other countries with my girlfriend. Now she is studying in Essen, a large city in Western Germany. I recently went to stay with her-----it was my first visit to Germany! Essen is a very large city. It has all the conveniences of any large city so I felt immediately at home. I love the variety of shops, restaurants, shopping malls, cocktail bars, nightclubs, parks and even a lake. There is also a city-wide network of trams, which makes getting around a piece of cake!
I found the people to be really friendly, and most Germans speak very good English which made life easy for me. I was surprised by the casual attitude to alcohol in Germany, where it seems normal for people to drink beer on the street, or on the tram. My girlfriend and I visited two famous local cities, Dǘsseldorf and Cologne, which are both on the Rhine River. Dǘsseldorf is an urban metropolis with a great variety of restaurants. We took a boat tour on the river and went up the Rhine tower, a really tall building which offers great views across the city. Cologne, as you might know, is world famous for its perfumes. The cathedral there is an unmissable landmark. We made the effort to climb to the top of one of the cathedral’s tower. The spiral(螺旋的) stairs seemed endless, but it was worthwhile for the impressive sights from the top.
We also went in a cable car over the river and tasted a German delicacy called “Spaghettieis” which is ice cream with strawberry sauce! I also got to try the famous German sausage. I must admit, I really enjoyed the food! The only disappointment was the grey and rainy weather, which proves that Britain does not have the worst weather in Europe!
1.Why did the writer feel lucky this year
A. He will have a chance to live in Germany.
B. He met his girlfriend in France by chance.
C. He got an opportunity of learning in Germany.
D. He was able to live in France and visit other countries.
2.What do Dǘsseldorf and Cologne have in common
A. They are both famous for unique perfumes.
B. They both serve traditional German sausage
C. They both have many towers with a long history.
D. they both offer wonderful views from the tower top.
3.According to the writer, which country has the worst weather in Europe
A. Britain. B. Germany.
C. France. D. Italy.

There is no sound worse than an alarm clock first thing in the morning.Some of us are the type to jolt out of bed with a smile.1. While I have a love-hate relationship with mornings,I have found that there are indeed ways to make mornings a little more bearable.

One way to combat the morning blues is to mentally plan out your day right when you wake up to prepare yourself for the day.Give yourself at least one little thing to look forward to each day.2.
Meditate.

Go with a friend or classmate to breakfast,school,etc.
5. Sharing the first moments of the day with others will fuel your mind and let you ease into your day. Also,having a regimented (受管制的) morning routine with others will help ensure that you are on-time for school and that you have a reason to get up in the morning.
