Anyone who has ever lost keys or money will have wished for a simple but effective way to make sure it never happens again. A US company is trying to help.
Using a tiny microchip which is implanted into the arm, they have come up with a replacement for cash or credit cards that cannot be left at home or dropped on the bus.
The Verichip is about the size of a grain of rice and works using radio frequency identification technology. At a shop, a radio frequency “reader” would send a signal and the chip in your arm would respond with your unique identity number. That would give the “reader” your financial information, and money could be taken directly from your accounts and you wouldn't even have to reach for your wallet.
The company also hopes to include other information on the chip, such as medical records, building security codes (密码) and passwords, making life even easier.
But not everyone is happy with the developments. Critics say that a lot can go wrong with the chip. A clever thief could build a fake (假的) reader that would steal your information without you knowing. So your money could still be stolen. Privacy is a big issue too. Stores, or even the government, only need to track the chip to find out what you buy, how much you spend and where you go.
And if you wanted to get rid of your chip, you would need an operation to remove it.
1.The Verichip is ________.
A．the identity number B．the security code
C．a tiny microchip D．a radio reader
2.Which is true of the Verichip?
A．Your information on it will always be safe.
B．Medical records have already been included.
C．You can easily reach for your wallet using it.
D．An operation has to be performed to remove it.

Have you ever been to the beautiful country of Holland and its capital Amsterdam? Anyone who has traveled to Amsterdam would probably agree on one thing: Amsterdam’s story is a tale of two cities—one during the day and a completely different one at night.
During the day, the largest city in Holland sits quietly on the Amstel River. You can rent a bicycle, visit the Van Gogh or Anne Frank museum, or take a water taxi. But when the sun goes down, the partying begins. In the big clubs and in coffee shops, tourists gather to hang out, talk politics and smoke.
Several areas of the city clearly show the two worlds that rule Amsterdam. And they’re all within a short taxi ride of each other. For example, Dam Square attracts daytime sightseers to its festivals, open markets, concerts and other events. Several beautiful and very popular hotels can be found there. And there’s the Royal Palace and the Magna Plaza shopping mall.
But at night party-seekers come to the square. Hip hop or funk music is heard there. So if you come, be ready to dance. The clubs don’t close down until 4 am.
And while you’re there, check out the various inexpensive ways to tour the city. Don’t worry about getting lost. Although Dutch is the official language, most people in Amsterdam speak English and are happy to help you with directions. And you’ll notice that half the people in the streets are on bicycles they rent.
Amsterdam also has a well-planned canal system. For about 10 dollars, you can use the canal bus or a water taxi to cruise (巡游) the "Venice of the North".
The city has a historic past. One impressive place to visit is the Anne Frank House on Nine Streets. It was there that the young Jewish girl wrote her famous diary during World War II. Visitors can view Anne’s original diary and climb behind the bookcase to the room where she and her family hid from the Nazis for two years.
59. The following means of transport are available to visitors in Amsterdam EXCEPT __________.
A. a carriage. B. a bicycle. C. a canal bus. D. a water taxi.
60. When getting lost, a visitor can ask natives for directions in .
A. only Dutch B. Dutch or English C. only English D. Spanish and English
61. What can you learn about by visiting the Anne Frank House?
A. The happy experience of a girl survivor. B. The glorious past of Amsterdam.
C. The hard life of the Jewish in World WarⅡ. D. The hobbies of the Dutch.
62. The passage is intended to .
A. call up people’s memories of World WarⅡ
B. tell readers what A Tale of Two Cities is about
C. instruct visitors what to do and see in Holland
D. offer readers some information about Amsterdam

Anyone who has ever played the game of Tetris (俄罗斯方块) knows the game’s surreal ability to spill into real life. After you shut off the game, you still see those Tetris blocks falling in your mind. You're grocery shopping and find yourself thinking about rearranging items on grocery shelves. Your mind continues to play the game, even when you're physically not.
Robert Stickgold, a Harvard professor, noticed something similar after a day hiking a mountain. That night, he dreamt he was still going through the motions of mountain hiking. Curious about this, he tried something: he got a group of college students of various skill levels to play Tetris and let them sleep in the Harvard sleep lab.
Over 60% of the students, including those who suffered from amnesia (健忘症), reported dreams of images of Tetris pieces falling, rotating (旋转), and fitting together. Interestingly, half the Tetris expert students reported such Tetris dreams, while 75% of the beginners did.
A study found that playing Tetris can grow your brain and make it more efficient. Adolescent girls played the game for an average of 1.5 hours a week over three months. The cerebral cortex (大脑皮层) of the girls grew thicker, while brain activity in other areas decreased. Richard Haier, who had found that there was a "Tetris learning effect", in which the brain consumed less energy as mastery of the game rose, concluded, "The brain is learning which areas not to use."
Haier's study showed that as the girls practiced playing the game, nerve cells made connections, communicating through synapses (a synapse is a connection between two nerve cells). When you learn something, you change those connections. Every time you reactivate(激活) a circuit, synaptic efficiency increases, and connections become more durable and easier to reactivate. Stickgold says sleep plays a role in this memory process.
So to sum up, whenever you do specific tasks over and over again, they take up less of your brain power over time. And that’s pretty amazing.
1.What does the underlined part ‘surreal ability’ in the first paragraph mean?
A. The game can help people arrange things in life.
B. The game can be applied to many aspects of life.
C. There are great similarities between the game and things in life.
D. The mind continues to play the game when we are doing other things.
2.What can we learn from Stickgold’s study?
A. More than half of the students dreamed of images of Tetris.
B. Students having bad memories didn’t dream of the game.
C. The Tetris expert students were more likely to dream of the game than the beginners.
D. More than half of the Tetris expert students didn’t dream of the game.
3.Playing Tetris for a long time can help ________.
①grow one’s brain
②one’s brain function efficiently
③arrange things tidily in life
④improve the adaptability of one’s brain
A. ①②③ B. ①②④
C. ②③④ D. ①③④
4.The purpose of the passage is to ________.
A. encourage people to play Tetris
B. warn people to focus while doing things
C. warn people not to play games before sleep
D. tell people they will improve at something if they keep doing it

[1] Have you ever had the wish to live another 100 years or more? Experts say that scientific advances will some day enable us to live tens of years longer than what is now seen as the natural limit of the human life span.
[2] “I guess we are knocking at the door of living longer,” said Michael Zey, a Montclair State University business professor and author of two books on the future. “I think by 2075 we will ____________ and that’s a conservative estimate（保守的估计）.”
[3]At the conference in San Francisco, Donald Louris, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology（纳米技术） make it likely that humans will live in the future beyond what has been possible in the past. “There is a great push so that people can live from 120 to 180 years,” he said.
[4]However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to live past about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
[5]Scientists also differ on what kind of life the super aged might live. “It remains to be seen if you pass 120, you know; could you be healthy enough to have a good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Centre. “At present people who could get to that point are not in good health at all.”
1.What is the main idea of the passage? （no more than 10 words）
2.Please fill in the blanks in the second paragraph with proper words.（no more than 5 words）
3.According to Donald Louris, what will enable humans to live longer?（no more than 8 words）
4.What does the word “it” （Line 1, Paragraph 4) probably refer to? （no more than 10 words）
5.What did Leonard Poon worry about? （no more than 15 words）

Anyone who has ever tried to stop smoking knows how difficult it is to quit. There is no lack of information about how unhealthy smoking is for you- not to mention the unpleasant smell. So why would teens ever begin to smoke?
1. Research shows that the majority of smokers lit up their first cigarette in their early or mid-teens, precisely at
a time when children are beginning to establish their own identity apart from their parents. Smoking can be an act of rebellion(反抗) against parents or authority figures, as well as a way to fit in with others and feel accepted.Here are some things that parents can do to help a child stay smoke-free.
Start talking to your teen about how bad smoking is for him early, well before his teens. Keep talking, too. 2.
3. For example, smoking makes your hair and clothing smell bad, stains the teeth, and reduces your lung power to play sports.
4. Talk about the addictive power of smoking and tell him while those few cigarettes are his choice, the addiction that occurs shortly afterwards makes him powerless to decide whether or not he wants to light up.
Work on self-esteem(自尊) and self-confident with your teen. Much of the attraction of smoking is to gain acceptance. 5.
Young teens live in the moment, too.
Play on your child’s desire to make his own choices.
The answer lies in the develop-mental stage of your teens.
Give your child the facts, but focus on the things he can relate to.
Help your teen to feel good about himself without having to smoke.
On
e discussion will not be enough to help your child not to smoke.They won’t be aware of how powerful addictive smoking is in a very short time.
