You don't need to get in a time-traveling machine to see how technology will reshape our lives, such as the way we shop．Several new technologies that are to change your buying habits already exist．Let's see what's in store for your future shopping．
Try it on, virtually （虚拟的）．Want to shop online for a new pair of eyeglasses? You don't need to guess which pair looks best on you. Go and see the eBay Fashion iPhone app to try a pair of eyewear you're checking out on a picture of your face．But what if you want to buy something bigger? Thanks to Microsoft Kinect's motion tracking camera, you can cover clothes on your screen body．You can even choose the background of your virtual fitting room to enrich your shopping experience．
Get a perfect, custom fit．Everyone's body is shaped differently．To get a perfect fit, you sometimes have to get your clothes changed．But by using 3D scanning technology, all the clothes you buy will fit your body perfectly．Some companies scan your body using High-tech to get the most accurate measurements, so they can make special clothes just for you．
High-tech shopping carts and checkout counters．High-tech shopping carts could, in time, be a common sight in malls and supermarkets．Microsoft Kinect-enabled carts are currently under test．The cart can follow you along the aisles （通道）, controlled merely by your movement and your voice．In China, a supermarket chain introduced tablet-equipped carts that guide shoppers around the stores' aisles．
In the United States, several supermarkets use a device called Scan It that gives buyers the freedom to scan purchases on their own while they shop．While it's great not having to line up at a checkout counter, we wouldn't mind it if the store used Toshiba's new Object Recognition Scanner．The machine identifies a product as soon as it's placed in front of a camera just by its shape and color, even if it has no bar code．What's the best title for this text?

Many people write to newspaper and magazines to express their opinions. Letters to the editor must carry the writer’s full name, address and telephone number, although the information is not necessary for publication. This requirement to provide personal particulars is a clear indication that writers are held responsible for what they say. When a writer wants his voice heard, he needs to claim ownership of his voice. Responsibility is the name of the game.
“People today prefer living together to putting their signatures on a marriage certificate because they refuse to accept responsibility for the relationship,” said social worker Ken Yip, “and this is what is causing a lot of family problems.” When we sign a paper, for example, a business contract or a bank document, the signature is a seal of consent, an agreement to take the matter seriously. Most governments and many organizations will not process written complaints if they do not bear the writer’s signature. The absence of a signature, they explain, tells us that the writer cannot be too serious and therefore does not deserve a reply.
There are people who wish to remain anonymous（匿名的）for various reasons. Multi-billionaire Mr. King donates generously to charity several times a year. He gives simply because he wants to help but not for the publicity his donations may bring, and he does not want his good deeds to make news. In other cases, people insist on anonymity because they are afraid of the consequences of revealing their identity. Crime witnesses may be willing to assist the police, but most are unwilling to give their names when reporting a crime.
Name or no name? The answer is very personal and lies in how much we want to get involved. We all have a name. It is a matter if responsibility to use it when we make a statement, a claim or an accusation. We all want to honour our own name, and it is only by stamping our expression of an opinion with our own name that we honour what we say. What does the writer mean by saying “Responsibility is the name of the game”?
| A．Writers need to provide their personal information in the game. |
| B．Publication must bear the writer’s full name, address and phone number. |
| C．Writers should be responsible for their names. |
| D．Names are required to indicate writers’ responsibility for what they say. |
The second paragraph suggests that a paper without a signature may _______.
| A．help to end a relationship | B．not get a reply |
| C．be accepted all the same | D．become a family problem |
Some people don’t want their names known because they are ________.
| A．hesitant to make a donation | B．unwilling to draw public attention |
| C．afraid of an accusation | D．ready for involvement |
The passage is mainly about _______.
| A．honour and writers | B．identity and signature |
| C．signature and responsibility | D．anonymity and signature |
| 237 West Palmdale Boulevard Fresno, California 93706 AmToy Corporation Suite 15 TransAm Building San Francisco, California 94115 November 20, 2008 Dear Sirs, As a concerned parent, I am writing to protest your recent advertisement for Electro-Robo seen in local media is California. Specifically, I am referring to newspaper and magazine ads（attached to this letter）published the week of November 15. Children respond to your type of advertising in an immature way; that is, they are unable to understand how expensive some toys are for middle-class parents. Further, you product is violent in nature. Youth advertisement gives children the impression that it's fine to have "two guns and laser eyes." You also suggest that children need your toy to protect them "when you go outside." This is not a healthy attitude for children to have. I hope you will stop advertising your product in such a way that may harm our children. Sincerely yours, （Mrs.） Alma Hernandez President, Parents for Non-violent Toys Enc. |

The surprising experiment I am about to describe proves that air is all around you and that it presses down upon you. Air pressure is a powerful force. When you swim underwater, you can feel water pushing down on your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’s surface.
The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now for the experiment！
What you need
•A hard-boiled egg without the shell
•A bottle with a neck slightly smaller than the egg
•A piece of paper
•A match
Method
1） Check that the egg will sit firmly on the neck of the bottle.
2） Tear the paper into strips and put the strips into the bottle.
3） Light the paper by dropping a burning match into the bottle.
4） Quickly sit the egg on the neck of the bottle.
Result
Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.
Why it happened
As the paper burns, it needs oxygen and uses up the oxygen （air） in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! This proves that air is all around and that it is pressing down on it. Why is there the need to take care when you are doing the experiment?
| A．The bottle could break. |
| B．You need to light the paper with a match. |
| C．The egg needs to be shelled. |
| D．The egg has to be perfectly placed on the neck of the bottle. |
In the experiment, the burning inside the bottle can___.
| A．equalize the air pressure inside and outside |
| B．make a seal in the neck of the bottle |
| C．finish up the oxygen inside the bottle |
| D．produce more oxygen inside the bottle |
How did the egg put into the bottle？
| A．The oxygen inside the bottle sucked the egg in. |
| B．It became saft without the shell. |
| C．The neck of the bottle was wide enough. |
| D．The outside air pressure forced it into the bottle. |
The experiment is carried cut to prove ______.
| A．water pushes on your body when you swim underwater. |
| B．the earth is surrounded by a layer of air called the atmosphere. |
| C．the pressure of air around us has a powerful force. |
| D．the air pressure is not equalized around us. |
Outside her shabby cottage, old Mrs. Tailor was hanging out laundry on a wire line, unaware that some children lay hidden in the leaves of a nearby tree watching her every move. They were determined to find out if she really was a witch.
They watched as she took a broomstick to clean the dirt from her stone steps. But, much to their disappointment, she did not mount the broomstick and take flight. Suddenly, the old lady’s work was interrupted by the cackling of her hen—a signal that an egg had been laid in the warm nest on top of the haystack.
The old broomstick was put aside as she hobbled off towards the haystack followed by Sooty, a black cat she had rescued from a fox trap some time back. With only three legs, it was hard for Sooty to keep up with the old lady. The cat provided proof—the children were sure that only a witch could own a black cat with three legs.
There, standing on a wooden box, was Mrs. Tailor, stretching out to gather her precious egg. Taking the egg in one of her hands, she began to climb down when, without warning, the box broke and the old lady fell.
“We have to got and help her,” whispered Amy.
“What if it is a trick?” replied Ben.
“Don’t be silly, Ben. If she were a witch, she would have turned us into frogs already,” reasoned Meg. “Come on Amy, let’s go.” The girls climbed down the tree and ran all the way to the haystack.
Approaching carefully, they could see a wound on the old lady’s face. She had knocked her head on a stone and her ankle was definitely broken. “Go and get Dad,” Amy yelled to her brother. “Tell him about the accident.”
The boys did not need another excuse to leave. They ran as fast as they could for help, hoping that Mrs. Tailor would not wake and turn the girls into frogs. . Why were the children hiding in the tree?
| A．They wanted to watch Mrs. Tailor do her housework closely. |
| B．They were playing a hide-and-seek game |
| C．They wanted to find out if the rumors about Mrs. Tailor were true |
| D．They were pretending to be spies |
. Mrs. Tailor stopped sweeping when____
| A．her front steps were clean | B．she noticed the children in the tree |
| C．she was ready to take a flight | D．she heard the hen cackling |
. Ben did not rush in help Mrs. Tailor because_____
| A．he thought that she could be tricking them |
| B．he knew that they could not have been in the tree |
| C．he did not see the old lady fall down |
| D．he was afraid of the three-legged cat |
. Which of these old sayings best suits the story’s lesson for us?
| A．Make hay while the sun shines. |
| B．Never judge a book by its cover. |
| C．People in glasshouses should not throw stones. |
| D．A bird in the hands worth two in the bush. |

Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience.
Between 65,000 and 35,000 years ago, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.
A new study from Switzerland sheds light on where ice sheets melted during the ice age.
It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern areas. This surprised the researchers from the University of Bern.
Scientists have long assumed(认为) that most of the ice that melted was in the Northern hemisphere(半球) during the 30,000-year-long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea, the ice can easily just slip to the ocean instead of building up.
The researchers used a computer model to look at the ways the ice could melt and how it might affect sea levels. They compared these results to evidence(迹象) of how temperatures and currents actually changed during that time.
The model showed that if it was only in the Northern hemisphere that ice melted, there would be a bigger effect on ocean currents(洋流) and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too.
The only reasonable conclusion, the scientists could make, was that the ice melted equally in the North and the South.
It is still a mystery(谜) as to what caused the temperature changes that caused the ice to melt.

D. to explain what a temperature cycle is
75. Which of the following best shows the relationship between ice, ocean currents and temperatures according to the text?
A. Ice can easily slip into the ocean.
B. Temperature and currents changed as a result of ice melting.
C. Temperature changes lead to ice melting or water freezing, which in turn has an effect on ocean currents and temperature.
