    You don't need to get in a time-travelling machine to see how technology will change our lives, such as the way we shop. Several new technologies that are to change your buying habits already appear. Let's see what's in store for your future shopping.

    Try it on, virtually（虚拟地）. Want to shop online for a new pair of glasses? You don't need to guess which pair looks best on you—use the eBay Fashion iPhone app to try a pair of glasses you're checking out on a picture of your face. But what about buying something bigger? Thanks to Microsoft Kinect's action tracking（跟踪）camera, you can cover clothes on your screen body. You can even choose the background of your virtual fitting room to improve 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（扫描）your body using High-tech to get the real sizes, so they can make special clothes just for you.

    High-tech shopping carts（推车）and checkout counters（收银台）. High-tech shopping carts could be common in malls and supermarkets in the future. Microsoft Kinect-enabled carts are under test. The cart can follow you along the aisles（通道）, controlled only by your movement and your voice.

    In the United States, several supermarkets use a certain set called “Scan It” that gives buyers the freedom to scan products on their own while they shop. If we don't want to wait in line before the checkout counters, we can use Toshiba's new object Recognition Scanner. The machine identifies（辨认）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.

    Many animals are in danger of dying out. We can see the number of animal species decreases faster and faster and this trend will continue. From 1980 to 2010, at least I million animal species disappeared. Worse still, more and more wild animals are in great danger. It is not a piece of terrible news; it is a fact, a harsh reality. Unfortunately, we may not see these animals in the near future.

    Why is the number of animal species declining year by year? Apparently animals have become victims of fashion industry. Animal skin has been used to make fashionable clothes and these clothes are sold at a high price. So some greedy people begin to kill animals in a large quantity.  This irresponsible behaviour not only breaks the balance of nature but also endangers the living environment of human beings.

    As far as I am concerned, something must be done to stop this illegal action. We believe "no buying, no killing". First, we must make concerning laws to protect these animals in danger.  Second, we must take some measures to protect animals effectively. Animals are our friends and part of our environment. Third, we should raise people's awareness to protect animals and our environment.  In this way, we can build a harmonious society and ensure a sustainable development.

Green is an important color in nature. It is the color of grass and the leaves on trees. It is the color of most growing plants, too.

Sometimes, the word green means young, fresh and growing. Sometimes, it describes something that is not yet finished or plants that are not ripe.

For example, a greenhorn is someone who has no experience, who is new to a situation. In the fifteenth century, a greenhorn was a young cow or ox whose horns had not yet developed. A century or so later, a greenhorn was a soldier who had not yet had any experience in war (战争) .By the eighteenth century, a greenhorn had the meaning it has today——a person who is new in a job.

About one hundred years ago, greenhorn was a popular expression in the American west Old—timers used it to describe a man who had just arrived from one of the big cities in the east. The greenhorn didn't have the skills that he would need to live in the hard, rough country.

Someone who has the ability to grow plants well is said to have a green thumb. The expression comes from the early nineteen hundred.

A person with a green thumb seems to have a magic touch that makes plants grow quickly and well. You might say that the woman next door has a green thumb if her garden continues to grow long after your plants have died.

The Green Revolution (革命) is the name which was given some years ago to the development of new kinds of rice and other grains. The new plants produced much larger crops. The Green Revolution was the result of hard work by agricultural (农业的) scientists who had green thumbs.

The dragon is the fifth sign of the Chinese Zodiac (生肖). There are 12 Zodiac in Chinese culture. In fact, the Chinese dragon, also known as long, doesn't exist (存在). But Chinese people have loved it so much for {#blank#}1{#/blank#} of years.

Chinese Dragons play an {#blank#}2{#/blank#} role in Chinese culture. You can always find something about dragons when you are learning {#blank#}3{#/blank#} Chinese culture.

Emperors (皇帝) in ancient China were {#blank#}4{#/blank#} as the sons of dragons. Chinese dragons are the symbols of being lucky, {#blank#}5{#/blank#} and noble. But they are described as monsters in Western stories.

Chinese people believe dragons could control the weather. They live at the {#blank#}6{#/blank#} of seas, rivers, lakes or anywhere with water. In many {#blank#}7{#/blank#}, Chinese people perform a "dragon dance" to please the dragon king and make sure good weather and a good harvest. It was {#blank#}8{#/blank#} that a dragon helped Yandi and Huangdi open the prelude (序幕) to Chinese civilization (文明). So Chinese people call {#blank#}9{#/blank#} "descendants (子孙) of the long".

In the West, dragons also have a long history. What may be surprising, however, is that the dragons {#blank#}10{#/blank#} similar origins (起源). Both Eastern and Western records said dragons are like snakes.

Giving hongbao ( red packets ) is a tradition in China . Traditional red packets are 1 decorated with gold Chinese characters (汉字) such as 2 and wealth.

Red represents (代表) luck in Chinese culture. That is why red packets are used during Chinese New Year and other celebrations.

How to give and receive red packets

It is a 6 act to give and receive red packets . So red packets are always 7 and received with both hands.

Someone who receives à red packet at Chinese New Year or on his or her birthday should not 8 it in front of the giver. However, things are 9 at a Chinese wedding(婚礼), where the guests usually give the red packets to the attendants and sign their 10 on a long piece of paper. The attendants will open the packets at once, count (点数目) the money inside, and record it on a register (登记簿) next to the guests' names.
