When we can see well, we do not think about our eyes often．It is only when we can not see perfectly that we come to see how 
important our eyes are．
People who are nearsighted can only see things that are very close to their eyes．Many people who do a lot of close work, such as writing and reading, become nearsighted．Then they have to wear glasses in order to see distant things clearly．
People who are farsighted face just the opposite problem．They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length．If they want to do much reading, they must get glasses too．
Other people do not see clearly because thei
r eyes are not exactly the right shape．This, too, can be corrected by glasses．Some people’s eyes become cloudy because of cataracts．Long ago these people often became blind．Now, however, it is possible to operate on the cataracts and remove them．
When night falls, colors become fainter to the eyes and finally disappear．After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers．Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction．This is because when you turn your head, you are looking at the thing too directly．Men on guard duty sometimes think they see something moving to one side of them．When they turn to look straight at it, they can not see it any more, and they believe they were mistaken．However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark．We don’t know that our eyes are of great importance until ________．
| A．we think about our eyes | B．we cannot see clearly |
| C．we wear glasses | D．we have to do much reading |

On a cool November afternoon in Fleming Island, Florida, Melissa Hawkinson, 41, was driving her five-year-old twins home from school when she saw a sudden splash in Doctors Lake just ahead. What was that? She thought. As she drove up to the scene, she saw a half-submerged car sinking about 30 yards offshore. “It was going down pretty quickly,” Hawkinson recalls. She stopped the car near the boat ramp and ran toward the water. Water is going to be cold, she thought.
She took off her vest and leather boots, got into the icy water, and swam to the car, where she found Cameron Dorsey, five, trapped into his car as the swirling water rose around him.
Hawkinson tried to open the door, but it was locked. So she pushed and pulled hard on the partially open window until she could reach through and unlock the door. She pulled the boy free, swam to shore, and handed him off to onlookers who were only watching them on a dock. The driver, the boy’s suicidal father, swam back to land on his own. Afterward, Hawkinson sat on the shore wrapped in a blanket. “For ten or 15 minutes, I couldn’t stop shaking,” she said.
There’s nothing visibly extraordinary about Melissa Hawkinson, an energetic stay-at-home mom with brown hair and a sweet smile. Yet something made her different from the dockside onlookers that day. Why do some people act quickly, willing to take a risk for a stranger? What makes them run toward danger rather than away from it? Hawkinson, the Granite Mountain Hotshots (能手，高手)---19 of whom lost their life this past summer in Arizona--- every hero who puts his or her life on the line to save another: what makes them brave?
Moreover, can bravery be learned, or is it a quality with which you are born? The answer is complex. Bravery taps the mind, brain and heart. It comes from instinct, training and sympathy. Today, neurologists, psychologists and other researchers are studying bravery, trying to uncover the mystery.It can be learned from the passage that _______.
| A．Melissa Hawkinson was a 41-year-old nurse |
| B．it was spring when the accident happened |
| C．Melissa Hawkinson was picking up her five-year-old son |
| D．Melissa Hawkinson was kind and courageous. |

| A．Not everyone was ready to risk saving the five-year-old boy.. |
| B．The father committed suicide because of the divorce. |
| C．The father was saved in the end by Melissa Hawkinson. |
| D．No one else was available except Melissa Hawkinson. |
How does the writer find other people on the dockside?
| A．Warm and ready to help | B．Thoughtful |
| C．Kind of cold-blooded | D．Not skillful at swimming |
What is the writer’s purpose of writing this passage?
| A．To set us thinking what makes people brave. |
| B．To call on us to learn from such people as Hawkinson. |
| C．To remind people of risk while saving others. |
| D．To show people bravery can be learned. |
You may not be aware, but digital currency (货币) is a big part of the Internet world. QQ Coins can buy you accessories (配饰) for your QQ images. More importantly, a new digital currency, Bitcoin, is bringing the world’s commerce online.
If you’re traveling, you can spend Bitcoins at restaurants and hotels listed at BitcoinTravel.com. In China, Bitcoins can be used to buy goods at about 134 online shops on Taobao. And at a café named 2nd Place in Beijing, you can even buy fresh coffee with Bitcoins.
So what makes Bitcoin so attractive to investors?
First of all, the Bitcoin system is not controlled by anyone. One central authority cannot make policies to change the value of Bitcoins. The fixed amount of Bitcoins also means they cannot lose value through inflation(通货膨胀), as all forms of paper money have done over time.
In addition, accounts in the Bitcoin system are anonymous and transparent. Users can set up an account easily and track every Bitcoin. All of these features seem to make Bitcoins immune(有免疫力的) from loss, but that is not entirely true.
“The value of Bitcoins can vary wildly as no central government makes the price of them steady. If the value drops suddenly, investors cannot get any compensation(赔偿),” Zhao Qingming, a senior researcher at China Construction Bank, told China Economic Weekly. And Bitcoins, unlike company shares, are not backed by any tangible funds, which also adds to their risk.
While China will not recognize the digital currency anytime soon, Xinhua said, lawmakers and officials at a hearing on Nov. 18 in the US made positive comments about Bitcoin.
Ben Bernanke, outgoing chairman of the Federal Reserve, told the Washington Post that “these types of creations, such as Bitcoin… may hold long-term promise, particularly if its system promote a faster, more secure and more efficient payment system.”Bitcoin is ______.
A. actually exactly like QQ Coins
B. only used online
C. a new currency used both online and in real life
D a country’s new digital currency.We can use Bitcoin to buy the following things except ______.
| A．online goods |
| B．goods at 134 online shops on Taobao |
| C．books in physical shops |
| D．coffee at a café named 2nd Place |
What is the disadvantage of Bitcoin?
| A．the value of it can rise and fall wildly. |
| B．It cannot lose value through inflation. |
| C．Every bitcoin in your account can be followed. |
| D．It can even be used at some specific restaurants and hotels. |

One hundred and thirteen million Americans have at least one bank-issued credit card. They give their owners automatic credit in stores, restaurants, and hotels, at home, across the country, and even abroad, and they make many banking services available as well. More and more of these credit cards can be read automatically, making it possible to withdraw or deposit money in scattered locations, whether or not the local branch bank is open. For many of us the “cashless society” is not on the horizon----it’s already here.
While computers offer these conveniences to consumers, they have many advantages for sellers too. Electronic cash registers can do much more than simply ring up sales. They can keep a wide range of records, including who sold what, when, and to whom. This information allows businessmen to keep track of their list of goods by showing which items are being sold and how fast they are moving. Decisions to reorder or return goods to suppliers can then be made. At the same time these computers record which hours are busiest and which employees are the most efficient, allowing personnel and staffing assignments to be made accordingly. And they also identify preferred customer for promotional campaigns. Computers are relied on by manufacturers for similar reasons. Computer analyzed marketing reports can help to decide which products to emphasize now, which to develop for the future and which to drop. Computers keep track of goods in stock, of raw materials on hand, and even of the production process itself.

| A．withdraw as much money from the bank as he wishes |
| B．obtain more convenient services than other people do |
