Always forgetting your long passwords(密码)? Worried about being hacked(被攻击)?All these worries will soon become history. Scientists have found that upper-casing(大写)your password can help you reduce the chance being hacked.
Usually passwords are six letters or more.However,50 percent of people choose a common word or simple key combination for their password. The most used passwords are 123456, abcdef and abc123. In fact, if your passwords are in lower-case(小写),it will be easily hacked by a hacker. According to a study, it only takes a hacker ten minutes to hack a six-letter password which is in lower-case, but if you make the letter in upper-case, it can take up to ten hours. So if you want to make your account much safer, you should make your password upper-case. Of course, you can also add numbers or symbols to your password. Most of the time a hacker’s computer has to work for 18 days to break a password, but if you choose a nine-letter password that includes numbers and symbols, it can take a hacher’s computer 44,530 years to break it.Scientists have found that your password is much safer for

Nowadays, many children spend hours a day looking at computer screens or other digital (数码的) products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome (视力综合症).
Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. “More children come into my office because their parents have noticed that they have headaches (头疼)or red eyes, or because their degree of short-sightedness appears to be increasing (增加)very fast and they’re worried,” he said.
Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don’t tell their parents, because they don’t want their games or the computer to be taken away. Another part of the problem is that people blink (眨眼睛) less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally(正常地) do in everyday life. If eyes can’t stay wet or are too tired, they will not be protected like normal.Which of the following may be caused by too much screen time?
| A．Having wet eyes. | B．Having headaches. |
| C．Having small eyes. | D．Having a toothache |

| D．Their parents don’t care about them. |

Happiness is for everyone. You don’t need to care about those people who have beautiful houses with large and swimming pools or those who have nice cars and a lot of money and so on. Those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
In fact happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you. W hen you study hard at your lessons, your parents are always taking good care of your life and your health. When you get success, your friends will say congratulations to you. When you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy too. All these are your happiness. If you notice them you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy because you have something else that can’t be bought with money. When you meet with difficulties, you can’t say loudly you are very happy because you have more chances to challenge yourselves. So you cannot always say you are poor and you have bad luck. If you take every chance you get, you will be a happy and lucky person.
| A．laugh at you | B．play jokes on you |

“An Englishman, even if he is alone, forms an orderly queue(队伍) of one,” wrote a famous British author, George Mikes．While this sounds funny, it’s a popular English stereotype (刻板印象)．From the supermarket to the subway, queues are a common sight on the streets of Britain．
Here in China, queues are normal, too．It is a part of everyday life．People queue most of the time, from buying tickets in the cinema to waiting for seats at a restaurant．But in certain situations, you’ll find yourself in the middle of a rushing crowd, such as getting onto the subway．Even away from the busy subway platform, queues are different．
One day I was standing in line at the supermarket．I left a small space in front of me．Within seconds, a girl walked by and took her place in that small space．I was surprised at first, but later I found these experiences very interesting．It is with these small, everyday differences that I get to live and learn in a new culture．
Back in Britain, the person spends about six months of their life waiting in a queue, according to the auction site MadBid．To pass the time, maybe they tell themselves the famous proverb: Good things come to those who wait．
| A．forming an orderly queue |
| B．being rude and loud |
| C．traveling on subways |
| D．spending more time waiting in a queue |
| A．call on people in China to queue more |
| B．compare queuing in two cultures |
| C．praise the English for following good manners |
| D．explain why people rush in some situations |
| A．Sports. | B．News. |
| C．Culture. | D．Business. |
