You have two eyes and they are set close together on the front of your face. Have you wondered why? The reasons are simple and important to the way you see the rest of your world.
Your eyes are like two small cameras. A camera catches an image of an object and records it on film. Similarly, when you look at something, each eye takes in what it sees and sends this image to the back of the eyeball. Because your eyes are set close together, they view the world from about the same height but from slightly different angles. Working as a team, the eyes send the images to your brain, which puts them together into a single, centered image.
Seeing in stereo means seeing with two eyes working together, which is called stereoscopic sight. This allows you to view the world in three dimensions, or 3-D. Seeing depth helps you to judge the distance between you and the objects you see and to adjust to the changing angle at which you see something as you move closer to or farther away from it. If images are coming from only one eye, however, only two of these dimensions----height and width----can be perceived. A world seen with one eye is thus two-dimensional, as in a photograph.
Now consider why your two eyes are on the front of your face. Think of other animals with the same arrangement. They are all animals that hunt, like lions and wolves. Their eyes face directly in front of them. This provides a field of sight about 180 degrees wide, which is called binocular(双眼的) sight. On the other hand, animals that are hunted have eyes on the sides of the head, which provides nearly360-degree field of sight. In order to stay alive, they need to see things coming from the sides and from behind. However, without stereoscopic sight, they have difficulty determining how far a danger is.
With sight both stereoscopic and binocular, humans share with animal hunters the ability to see from side to side and to accurately determine the distance. If you think it would be great to have another type of sight, perhaps with hundreds of tiny eyes like many insects do, think again! Each tiny insect eye sees only a tiny part. Besides, what if you needed glasses? Be glad for the eyesight that you have.According to the passage, the similarity of an eye and a camera is that they both .
| A．can imagine objects | B．can record images |
| C．provide centered images | D．work at the same height |
Stereoscopic sight is a result of having .
| A．two eyes close to each other that work together |
| B．hundreds of eyes, all seeing tiny parts of an image |
| C．a three-hundred-sixty-degree field of sight |
| D．one eye on either side of the head, each seeing a different image |
What is the meaning of the underlined word “perceived” in Para3 most similar to?
| A．known | B．seen | C．taken | D．understood |
We can infer from the last paragraph that .
| A．our eyes work like cameras |
| B．animal hunters are glad for the sight they have |
| C．the three dimensions are depth, height and width |
| D．human beings are fortunate to have such eyesight |

Consumer electronics once again topped the list of the most wanted gifts this holiday season. “Seventy-six percent of consumers who plan to buy holiday gifts say that they will spend money buying at least one technology product; definitely a solid vote of confidence for technology.” Steve Koenig is with the Consumer Electronics Association. He says the group’s latest research also shows that Americans this year are spending more on technology products.
“Here in 2012, $252 on average–the technology spend for consumers this year.” From tablet computers to smart phones, American shoppers have been lining up to get the newest and coolest electronic devices on the market. There are more choices today than ever before. “It’s kind of hard to make a decision.”
Tablet computers are one of the best-selling products this year. Brian Tong is Senior Editor of CNET.com. The website reports on tech news and examines the latest electronic products. He says the Apple iPad Mini is one of the most popular tablets. Its starting price is $329. One of Apple’s biggest competitors is the Google Nexus 7. It starts at $199.
“The hardware inside is more powerful than what’s in the iPad Mini, but also it offers you a lot of things like maps that work better than Apple’s maps.” Brian Tong says there is one reason why people may like the iPad Mini more than the Nexus 7. “If you just want to read books and surf the Internet, you don’t really need to get an iPad Mini, but if you want the largest group of apps that’s where the iPad and Apple’s ecosystem shines the most.”
Elman Chacon is with the electronics store Best Buy. He says another hot product this season is smart cameras. They connect to the Internet through Wi-Fi. This makes it easy for users to email or upload photographs directly from the camera. “You can literally take a picture, upload it into your Facebook in a matter of seconds. These things are pretty cool because they do a lot of things.”
Streaming media boxes also connect to the Internet. People are able to watch web content such as movies and YouTube videos on their televisions. Another popular item is wireless speaker systems. The newest ones work with any device that has Bluetooth technology, including smart phones, laptops and tablets.
With the growing popularity of Internet shopping, many consumers will visit a store first to look at a product, and then go online to find it at a lower price. Stores like Best Buy understand that and they want to stay competitive.
“We have something called the perfect match promise which means if you buy a certain device and you find it cheaper within 30 days we’ll go ahead and price match that for you.” Elman Chacon said.According to Brain Tong, ________.

Alibaba started taking the lead in China, simply enough, by connecting big Chinese manufacturers(制造商)with big buyers across the world. Its business-to-business site, Alibaba.com allowed business to buy almost everything. Alibaba’s advantage wasn’t hard to identify: size. Alibaba is just big, even by Chinese standards. Its marketplaces attract 231 million active buyers, 8 million sellers, 11.3 billion orders a year—and Alibaba is just the middleman. It encourages people to use its markets—not charging small sellers a percentage of the sale.
If you want a quick look into the influence of Alibaba on daily Chinese life, take my experience. I moved to Beijing almost a year ago and quickly got tired of visiting small stores across the crowded, polluted city of 20 million people in search of new electronics, bathroom furnishings, and anything else my wife wanted. “You’re looking for what exactly? Why not try it? ” my Chinese teacher asked me one day. With that, my wonderful new relationship with Alibaba began.
Alibaba’s original business-to-business model now is secondary to consumer buying. Chinese retail（零售）buying makes up 80% of Alibaba’s profit, and leading that group is Taobao, with 800 million items for sale and the most unbelievable selection of things you’ll ever find. TMall.com is Alibaba’s other big site, where you can find brand name goods from Nike and Unilever near the lowest prices.
What I have a hard time explaining to friends and family back in the U.S. is how China has gone beyond traditional shopping—big-box retailers especially —in favor of online purchases on Taobao and a few other sites. In smaller towns than Beijing, where big retailers have not yet traveled, shopping online is shopping, and shopping is Taobao.
I have a list of some of my recent purchases on Taobao for a sense of how extensive the marketplace is. Almost everything arrived a day or two after ordering with free shipping. I’m not even a big buyer, because I need friends to help me search the Chinese-language site. When I was searching my purchase history on my Chinese teacher’s iPad, which helps me buy goods, I looked through with great difficulty about 10 of her purchases for every one of mine.Alibaba’s advantage mainly lies in ___________.
| A．its big size |
| B．its business-to-business service |
| C．its not charging small sellers |
| D．its low price |
What can we learn from the underlined sentence in the passage?
| A．Alibaba is of middle size among all the online sites |
| B．Alibaba will continue to develop. |
| C．Alibaba stands out as the best online site. |
| D．Alibaba acts as a bridge between the buyers and sellers. |
What does the underlined word “it” in Paragraph 2 refer to?
| A．a new store | B．Alibaba |
| C．a business | D．a foreign website |
What can be inferred from the passage?
| A．The author’s Chinese teacher is also an online purchase lover. |
| B．Taobao has no obvious advantage over other similar online sites. |
| C．Alibaba’s business-to-business service earns more money than retail now. |
| D．TMall.com provides more profit than Taobao. |
What is the passage mainly about?
| A．Shopping online is TaoBao. |
| B．The influence of shopping online goes beyond traditional shopping. |
| C．Alibaba greatly influences people’s daily purchase in China. |
| D．How the author purchases online in China. |
Agatha Christie (1890-1976) was born Agatha May Clarissa Miller in Devon, England in 1890, the youngest of three children in a conservative, well-to-do family. Taught at home by a governess and tutors, as a child Agatha Christie never attended school. She became skillful at creating games to keep herself occupied at a very young age. A bashful child, unable to adequately express her feelings, she first turned to music as a means of expression and, later in life, to writing.
In 1914, at the age of 24, she married Archie Christie, a World War I fighter pilot. While he was off at war, she worked as a nurse. It was while working in a hospital during the war that Christie first came up with the idea of writing a detective novel. Although it was completed in a year, it wasn’t published until 1920, five years later.
“The mysterious Affair at Styles” gave the world the unique Hercule Poirot, a retired Belgian police officer who was to become one of the most enduring characters in all of fiction. With his waxed moustache and his “little grey cell,” he was “meticulous (careful to do things correctly), a tidy little man, always neat, orderly and a bit absurd.”
Christie wrote more than 30 novels featuring Poirot. Among the most popular were” The Murder of Roger Ackroyd”(1926), “Murder on the Orient Expredd”(1934), and “Death on the Nile” (1937).
Another of Christie’s most well-known and beloved characters was introduced in “Murder at the Vicarage” in 1930. Miss Jane Marple, an elderly single in the old- fashioned English village of St. Mary Mead, solved all manner of mysteries with intense concentration and instinct.
Christies ultimately (finally)became the acknowledged Queen of the Golden Age. In all, she wrote over 66 novel, numerous short stories and screenplays, and a series of romantic novels using the pen name Mary Westmacott. Several of her works were made into successful feature films, the most notable being Murder on the Orient Express (1974). In short, she is the single most popular mystery writer of all time. In 1971 she was awarded the high honor of becoming a Dame of the British Empire.Which of the following is the correct order in which the events happened?
a. Agatha became a Dame of The British Empire.
