A strong password is a word that is as difficult as possible to guess because it looks like a set of random characters （随机的字符）.

It's wise to use the whole keyboard to mix a password with letters, numbers and symbols. A password of 14 characters or more may be much safer.

The following tips will tell you how to create a strong and safe password:

Tip 1: Think of a sentence that is easy to remember, but difficult to guess. For example: “ My son Peter is five years old and my daughter Tina is one year old.”The whole sentence is so long that it can't be a password, so what you can do is to use the first letter of each word to make a new password that seems to be meaningless. That is “mspifyoamdtioyo”.

Tip 2: Make the password more difficult to guess by mixing big and small letters. One way to do this is to use big and small letters one after another. In this way this new password will be “MsPiFyOaMdTiOyO”.

Tip 3: Still using the sentence above, you can also add numers that are meaningful to you. As a result, the new password will be “Mspi5yOaMdTi1yO”.

Tip 4: Add punctuation（标点符号）and symbols to make the password much stronger. You may use symbols, numbers and punctuation to replace some letters which look similar. For example: “MsPi3y0@MdTi!y0”.(o=0, a=@, 1=!)

When you wave to a friend, you are using body language. When you smile at someone, you mean to be friendly. When you put one finger in front of your mouth, you mean "be quiet.''

    Yet, people in different countries may use different body languages.

    Once an Englishman was in Italy. He could speak little Italian. One day while he was walking in the street, he felt hungry and went into a restaurant. When the waiter came, the Englishman opened his mouth, put his fingers into it and took them out again and moved his lips. In this way, he meant to say, "Bring me something to eat." But the waiter brought him a lot of things to drink, first tea, then coffee, then milk, but no food.

    The Englishman was sorry that he was not able to tell the waiter he was hungry. He was ready to leave the restaurant when another man came in. The man put his hands on his stomach, and this body language was good enough for the waiter. In a few minutes, the waiter brought him a large plate of bread and meat.

    Finally the Englishman had his meal in the same way.

      Most middle school students wear uniforms. Some students like uniforms, but ①       don't. However, recently, a Japanese government survey(政府调查) shows that more students in Japan like uniforms now because ②school uniforms are more fashionable(时尚的) than they were before.

      Hiromi said, “I like school uniforms because I don't need to choose clothes every day. I think that fashionable uniforms are good. My high school uniform is fashionable, but there is a problem. Fashionable uniforms are too expensive.”

      Miki said that she didn't like fashionable uniforms because she didn't want to ③                        (在制服上花太多的钱). She thought that the uniforms should be changed(被改变). They should be cheaper and easier to get.

      Mitsuaki said, “I don't like school uniforms because I want to look different. I also agree that fashionable uniforms make many students want to wear uniforms in high school. If students like fashionable uniforms, it is good. ”

    When he was a small dog, he was very shy and he seldom barked. {#blank#}2{#/blank#} Maybe the dog just wanted to play with him, but he stayed behind me and looked at me sadly. {#blank#}3{#/blank#}

    However, my little dog barked loudly when there was a fire in the kitchen. I was very curious at that time why he became so excited and ran around me all the time. {#blank#}4{#/blank#}

    There is an old saying about pets in my hometown: to love your pet is to love yourself. I can't agree with it more. {#blank#}5{#/blank#} When we stay together, we enjoy ourselves very much. Life is just like this: we need a friend with us till the end.

    When this story happened, they were working around a very large house. Their job was to do the cleaning. It was not a difficult job, but sometimes it was a little dangerous, because they had to walk below where workmen were working. These workmen often dropped something from the top of the house many meters high to the ground.

    One morning Joe was working near the house with a cigarette(烟) behind one of his ears. Suddenly somebody on the top shouted, "Look out!" But Joe did not "look out". He looked up. And as he did so, a long knife missed Joe's head, but it cut off one of his cars. At once he put his hand to one side of his head and cried out, "I've lost an ear. Help! Help!" Jeff ran up to help his friend. "Look for my ear," Joe told him." It must be on the ground somewhere." Jeff looked everywhere for the missing ear. At last he found an ear on the ground. He picked it up and carried it to Joe. "Here you are", he said, "I've found it." Joe looked at it." No, that's not my ear." He said," Mine had a cigarette behind it"

    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一 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 Kindest 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(扫描) technology, all the clothes you buy will fit your body perfectly. Some companies scan 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 colour, even if it has no bar code.
