Though “nanometer” is now a fashionable term all over the world,few people know exactly what it is.It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.
Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles or crystallites of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?
Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation of the application of nano technology into medicine.
Ji(director Institute of Nanomedicine):
A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water.When people drink it,it will produce no special effect on human body.
Prof.Ji told the reporter,so far,the investigation of nano materials is still confined in the laboratory.No commercial micro products can be produced yet.With the present level of science and technology,the time of everyday goods age of daily use articles made of nanometer materials is still years away.
The commodities labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material,which makes them more abrasion resistant,much easier to be cleaned,or oil repelling or moth proof.
Prof.Ji explained that nano cup is a real cup.It can also be included in the list of nano products in a certain sense.But the nano cup has not changed its property and function as a cup.It is not a magical medicine for curing and health care.Which of the following shows the right relationship?
| A．nanometer<millimeter<micrometer<meter |
| B．nanometer<micrometer<millimeter<meter |
| C．micrometer<millimeter<nanometer<meter |
| D．millimeter<micrometer<nanometer<meter |
The underlined part in the last second paragraph but one is about_________.
| A．the strong points of nano cups | B．the shortcomings of nano cups |
| C．the uses of nano cups | D．the wonders of nano cups |
Which of the following does not show that nano cups are different from ordinary cups?
| A．Nano cups can’t make people healthier. |
| B．Nano cups are made of a different material. |
| C．Nano cups are much easier to be cleaned. |
| D．Nano cups are hard to produce. |
According to the text,nano cups in the market are_________.
| A．only traditional products |
| B．ordinary cups covered with a little nanometer material on the surface |
| C．cups made of a nano material |
| D．cups made of a mixed material |
India has a very vast history and heritage（遗产）. The country has witnessed some of the most important events in the past and every event has an effect of its own on the culture, religion, lifestyle, and economy of the country.

To get to the tennis court, Conner Stroud has to push his wheelchair there.
The 15-yea-old from North Carolina, US was born without legs. But when he picks up his racquet(球拍) and begins to hit a ball, you quickly see that the young man just want to win.
Stroud began playing tennis at age 5 at the small tennis club his parents own. For years, he played against able-bodied players by putting rubber on the stumps (残余部分) of his legs. Though he was a foot (30.48cm) or two shorter than many of the players he played against, he won a number of matches. He became well-known enough that he got to meet Rafael Nadal, his favorite player at the US Open in 2013.
“The most important thing is that he’s happy,” Nadal told reports about Stroud after that 15-minute meeting. “He’s playing tennis... That’s a great example of being happy even if life doesn’t give you everything.”
Stroud started playing wheelchair tennis at 13 and now he is No 1 in the US.
Earlier this summer, he played for the US in the world’s biggest junior wheelchair team tennis event --- the World Team Cup. He played six matches and won five of them as the US won the cup for the first time since 2000.
“He is a polite boy , but he will rip（撕扯）your heart out trying to beat you,” Jason Harnett, a United States Tennis Association coach, said of Stroud. “You see that attitude in a lot of the best players, whether they are able-bodied or disabled.
Teenage players can often get disappointed and angry. Racquets sometimes get thrown. Players shout at themselves after missed shots. Stroud never does that.
“ I just try to stay positive,” Stroud said. “After every point, I try to say I’m going to win the next point, or the next game, or the next game, or the whole match.
“ There’s always room to be positive . You can always win another time.”How is Conner Stroud different from other tennis players?
| A．He was disabled in a car accident. |
| B．He has been coached by his father since the age of 5. |
| C．He is too short to be a tennis player |
| D．He was born disabled , yet he plays tennis well. |
What impressed Rafael Nadal the most about Conner Stroud?
| A．His desire to win the match. |
| B．His happiness about playing tennis. |
| C．His faith in life, even though he is disabled. |
| D．The training he went through to play tennis. |
Which of the following words best described Conner Stroud?
| A．Positive | B．Independent |
| C．Humorous | D．Considerate |
With the development of science and technology, new inventions, especially new electronic products, have made people’s lives easy and convenient. But as the saying puts: A coin has two sides.
One day, I was walking in the park with a friend and his cell phone rang, interrupting our conversation. There we were, walking and talking on a beautiful sunny day and…I became invisible, absent from the conversation.
The telephone used to connect you to the absent. Now it makes people sitting next to you feel absent. Why is it that the more connected we get, the more disconnected I feel? Every advance in communications technology is a tragedy to the closeness of human interaction. With email and instant messaging over the Internet, we can now communicate without seeing or talking to one another. With voice mail, you can conduct entire conversations without ever reaching anyone. If my mom has a question, I just leave the answer on her machine.
As almost every contact we can imagine between human beings gets automated, the alienation(疏远) index goes up. You can't even call a person to get the phone number of another person any more. Directory assistance is almost always fully automated.
Pumping petrol at the station? Why say good morning to the attendant when you can swipe(刷)your credit card at the pump and save yourself the bother of human contact?
Making a deposit at the bank? Why talk to a teller who might live in the neighborhood when you can just insert your card into ATM?
Pretty soon you won’t have the burden of making eye contact at the grocery shop. Some supermarket chains are using a self-scanner so you can check yourself out, avoiding those check-out people who look at you and ask how you are doing.
I am not against modern technology. I own a cell phone, an ATM card, a voice mail system, and an email account. Giving them up isn't wise…they're a great help to us. It's some of their possible consequences that make me feel uneasy.
More and more, I find myself hiding behind e-mail to do a job meant for conversation. Or being relieved that voice mail picked up a call because I didn't really have time to talk. The communications industry devoted to helping me keep in touch is making me lonelier.
So I've put myself on technology restriction: no instant messaging, with people who live near me，no cell phoning in the presence of friends, no letting the voice mail pick up when I'm at home.Which of the following would be the best title of the passage?
| A．The Advance of Communications Technology |
| B．The Consequences of Modern Technology |
| C．The Process of Communications Revolution |

| D．We can use them less and communicate with the people around us. |
You may have experienced the annoyance of being fined because of parking illegally or finding your car towed away(拖走)after leaving it parked somewhere for a couple of minutes．But now a high-tech car sticker that’s designed to be stuck to a car’s windscreen could help motorists avoid such a situation．
The TowStop sticker sends a text message to a driver when touched by a traffic policeman，to allow motorists to send a reply and give them time to move their cars immediately．Frankfurt-based IT consultant，Daniel Kalliontzis，came up with the idea and is raising money to put his ￡43 sticker into production．
Car owners can put the sticker inside their car’s windscreen，having set it up with key information，such as their phone number．The slim design will include a sensor(传感器)that，when touched by a traffic policeman，will send a text message warning a driver of a possible fine．The driver could then type a reply for the policeman using a smartphone，which will appear on the sticker’s screen．
The smart sticker system will rely on the good will of traffic policemen and in a way，a German law．The law states：an officer has to choose the most efficient and inexpensive way for the car owner to remove the vehicle．It could be cheaper for the government to call the driver than to tow his car．
Mail Online asked the Department of Transport whether the sticker could be used in the UK in a similar way．A spokesman said，“In England there is no legal duty to warn the motorist before issuing the ticket．However，a policeman does have the discretion not to issue a ticket if he doesn’t think the situation is that bad or he just wants to issue a warning．”
So far，Mr．Kalliontzis has raised just over￡2,362 of his￡39,381 goal．If he manages to raise the money，the stickers will be shipped in June 2015．But it appears that car owners using the smart system could get some unnecessary warning messages，because anyone could touch the smart sticker．The author wrote the third paragraph to _______________．
| A．explain how a smart car sticker works |
| B．advise drivers to buy a car sticker |
| C．show the importance of a sensor |
| D．tell drivers how to park a car |
We may infer from the text that in Britain _______________．
| A．car owners don’t have to worry about a parking ticket |
| B．smart car stickers wouldn’t work as well as in Germany |
| C．traffic policemen prefer to call a driver rather than tow his car |
| D．the Department of Transport thinks highly of smart car stickers |
The underlined word “discretion” in Paragraph 5 can best be replaced by“____________”．
| A．trouble | B．pressure | C．freedom | D．opportunity |
What would be the best title for the text?
| A．Daniel Kalliontzis — a great inventor |
| B．Environment-friendly car stickers |
| C．Parking systems in Europe |
| D．End of the parking ticket? |
I was 16 when my father finally decided he would send me to wilderness camp for several months. He had threatened to do it many times before, but my mother had always managed to prevent him from doing so. This time he insisted on doing it.
The latest incident was the last straw. Impulsively(冲动地), I had pushed Mr. Ford, my math teacher, down a flight of steps at school. He broke his arm in two places. Anyway, he had agreed not to accuse me as a favor to my dad, who was in the middle of a tight race for sheriff(执法官) in our town. But my reckless behavior had my dad’s closest advisor talking.
“John, he’s your son and he’s a kid, but he is dragging you down,” I heard Jake Hutch tell my dad through his closed office door the night after I pushed Mr. Ford. “If you can’t make your son obey the rules, how can you make the law obeyed in this town?”
So, off to Pisgah National Forest I went. I imagined hours of untold abuse at the hands of some strong sergeants(军士). I was determined no to be broken. I was who I was.
Nearly every day for six months, a small group of other troubled teens and I carried our 30-pound backpacks on a difficult journey covering about 10 miles. We hiked in a rough wilderness that seemed untouched by civilization.
Our sergeants were firm but kind, not frightening as I had imagined. We learned how to make a fire without matches and create a shelter with branches and grass. We learned which plants were safe to eat out in the wild. I felt myself change. I was calm and often reflective. My old, impulsive self was gone.
One morning, six months later, my dad came to pick me up. I ran to hug him and saw relief and love in his eyes.
“So what’s it like being sheriff?” I asked on the ride home.
“I lost the race, Danny,” he said.
“I’m sorry, Dad.” I knew my behavior probably had a lot to do with the defeat.
Dad squeezed my shoulder and brought me close. “As long as I don’t ever lose you, I’m okay.”The author was finally sent to wilderness because _____.
| A．he could learn how to survive in the wild |
| B．his teacher insisted on giving him a lesson |
| C．he pushed his math teacher down the stairs |
| D．his mother feared that he would be accused |
