Better think twice before choosing a password for e-mail, online bank or shopping. Simple passwords are easy to be stolen.
A password is like a key to your home. If someone steals it, he’ll get chances to steal something else. We use passwords everywhere in our life. We are so used to passwords that we don’t pay any attention to them until we lose or forget one.
A study of 28,000 passwords recently stolen from a popular website showed that people often do the easy thing. It found that 16 percent took a first name as a password. Another 14 percent used the easiest keyboard combinations such as “12345678” or QWERTY. Five percent of the stolen passwords were names of television shows or stars popular with young people. Three percent of the passwords expressed feelings like “I don’t care,” “Whatever,” “I love you,” or their opposite, “I hate you.”
Robert Graham, who did the study, advises people to choose a password that is longer than eight characters with one capital letter(大写字母) and one symbol.
Of course, safe passwords don’t mean those hard to remember. Forgetting your password is sometimes a big headache for you. Maybe, the perfect password is easy for you and hard for others. The underlined word “password” in Paragraph 1 means __________.
| A．标志 | B．护照 | C．密码 | D．口诀 |
About 40% passwords are easily stolen because the users are ______.
| A．busy | B．lazy | C．stupid | D．careful |
Which of the following passwords is considered the safest?
| A．ZXCVBN. | B．password56. | C．wy64#0Mv. | D．I hate you. |
At present, too much carbon dioxide(二氧化碳) makes the earth warmer and warmer and causes terrible effect to human beings. To save our planet, to save ourselves, a new lifestyle called low-carbon life(低碳生活) becomes popular. Low carbon means low energy and no waste. It is necessary for everybody to learn to live a low-carbon life.
To live a low-carbon life, we’d better save energy as possible. Turn off the lights and TV whenever they are not needed. If possible, use cold water to wash clothes or dishes. Take a short shower and try to take a cold one when the weather gets warm. Don’t do the cooking with electricity.
To live a low-carbon life, we should eat less meat. Everybody knows eating too much meat makes people fat and easy to have heart disease, but maybe you don’t know keeping animals for food produces even more carbon dioxide than all the cars in the world, and being a vegetarian can help reduce one and a half tons of carbon dioxide a year. Maybe it is a little difficult, but it’s really necessary.
To live a low-carbon life, we are supposed to do less shopping. When we go shopping, we may drive a car or take other transportations. On the one hand, these machines pollute the air and waste energy. On the other hand, most of us always buy some useless things because of some advertisements. It is not only a waste of money but also causes trouble to the earth, because as you know, making everything will produce carbon dioxide more or less.
There are many other ways to live low-carbon life, such as recycling things, planting trees and reusing textbooks. If we can keep it a habit in our daily life, the earth will become a safer planet for us to live on.

What do people do with their old, out of date but still useful computers? Most people don’t know how to deal with them. Many old computers are put away. Many more are simply thrown away as rubbish.
Finally, some companies are thinking of ways to bring down the number of old computers. Sony has agreed to help recycle old Sony products(产品). Dell, Hewlett Packard and other companies now also take back some old computers of their own brands.
In some countries, laws have been passed, too. Computer companies have to pay for collecting and recycling their used products. And 70% of the computer waste must be recycled. The idea behind the laws is that computer companies themselves should pay for the cost. That will encourage them to make computers which are easier and cheaper to repair and upgrade(升级).
Yet many people are throwing away good computers, while others cannot afford them at all. Hundreds of organizations are working on this problem. They collect and repair old computers. Some also teach others how to repair computers. These repaired computers then go to schools, charities(慈善团体) or people who need them. Giving a used computer to one of these organizations can turn one person’s rubbish into someone else’s useful things and cut down waste, too.

A kind of little cars may take the place of today’s big ones many years later. If everyone drives such cars in the future, there will be less pollution in the air. There will also be more space for parking in cities, and the streets will be less crowded.
The little cars of the future will cost less. Driving will be safer, too, since these little cars can go only 65 kilometers an hour. The cars of the future will be fine for going around a city, but they will not be useful for a long way. Little cars will go 450 kilometers before they need to stop for more gasoline (汽油). If big cars are still used with the small ones, two kinds of roads will be needed in the future. Some roads will be needed for the big, faster cars and other roads will be needed for the small, slower ones.

Years ago, I lived in a building in a large city. The building next door was only a few feet away from mine. There was a woman who lived there, whom I had never met, yet I could see her seated by her window each afternoon, sewing or reading.
After several months went by, I began to notice that her window was dirty. Everything was unclear through the dirty window. I often said to myself, "I wonder why that woman doesn't wash her window. It really looks terrible."
One bright morning I decided to clean my flat, including washing the window on the inside.
Late in the afternoon when I finished the cleaning, I sat down by the window with a cup of coffee for a rest. What a surprise! Across the way, the woman sitting by her window was clearly seen. Her window was clean!
Then it dawned on me. I was always criticizing(批评) her dirty window, but all the time I was watching hers through my own dirty window.
That was quite an important lesson for me. How often had I looked at and criticized others through the dirty window of my heart, through my own mistake?
Since then, whenever I wanted to judge(评判) someone, I asked myself first, "Am I looking at him through my own dirty window?"
Then I try to clean the window of my own world so that I may see the world around me more clearly and correctly. The writer couldn't see everything clearly through the window because _________.
| A．the woman's window was dirty |
| B．the writer's window was dirty |

| D．the writer was near-sighted |
The writer was surprised that _________.
| A．the woman was sitting by her window |
| B．the woman's window was clean |
| C．the woman did cleaning in the afternoon |
| D．the woman's window was still terrible |
"It dawned on me" probably means "_________".
| A．I began to understand it | B．it cheered me up |
| C．I knew it grew light | D．it began to get dark |
It's clear that _________.
| A．the writer never talked to the woman before |
| B．the writer often washed the window |
| C．they both worked as cleaners |
| D．they lived in a small town |
From the passage, we can learn _________.
| A．one shouldn't criticize others very often |
| B．one should often make his windows clean |
| C．one must judge himself before he judges others |
| D．one must look at others through his dirty windows |
