Nowadays, computers and Internet are playing an important part in our life. We usually need to set passwords(密码) when we use computers and Internet. In order to keep our accounts (账户)and personal information safe, we must learn how to set safe passwords.
Experts have some useful advice for you. You’d better remember them. First, make your password out of capital(大写的)letters. It only takes a hacker(黑客)10 minutes to work out a 6-letter password made of small letters. But the same password in capital letters takes 10 hours to work out. Second, add numbers or symbols to your password. It may be much safer. Third, never use personal information for passwords and use different passwords for different accounts. At last, a user should change his or her passwords every 90 days. In this way, hackers won’t guess your passwords.
What do we usually need to do when we use computers and Internet?
Why must we learn how to set safe passwords?
How many pieces of advice are given to us by the experts?
Is it safe to use personal information for passwords?
How often should a user change his or her passwords?
Better think twice before choosing a password for email, 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% took a first name as a password. Another 14% used the easiest keyboard combinations such as “12345678”or “QWERTY”. 5% of the stolen passwords were names of television shows or stars popular with young people. 3% 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.

If you are not happy with China’s high Internet fees (费用) and slow speed, you are not alone. So is Premier Li Keqiang. On April 14, he said in a meeting that the government should speed up the Internet and lower the fees.
“The first question people ask at a new place is ‘Is there WI-FI’ because Internet service fees are so high,” said Premier Li. According to a recent survey by CCTV, the average cost(平均费用) of 1GB mobile Internet data per month(每月) in China is 100 Yuan, while it is only 60 Yuan in the US and 40 in Japan.
However, high prices don’t necessarily mean good service. The average Internet speed in China was 4.25Mbps(兆比特每秒)in 2014. South Korea had the fastest average Internet speed-25.3 Mbps. People can download a 1 GB movie within 6 minutes in South Koreas, but in China it would take half an hour.
To improve Internet services, the key is to build more fiber(光纤) networks. Through them we can send text, pictures and videos globally(全球地) in less than a second(秒), which offer high speed Internet. Besides, the lack of (缺少)market competition is another problem. Having more operators(运营商)besides China Unicom and China Telecom may lower the prices.
Why do people always ask for WI-FI at a new place in China?
A.Because they can’t use Internet without WI-FI. |
B.Because they can communicate with their families. |
C.Because they want to download movies. |
D.Because Internet service fees are too high. |
In 2014, ____ had the fastest average Internet speed.
A.China | B.USA | C.Japan | D.South Korea |
What is the key to improve Internet services?
A.To increase Internet service fees. |
B.To build more fiber networks. |
C.To learn from South Korea. |
D.To make the government know the situation. |

When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm and, in the winter especially, we were quite cut off from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that city life has its problems too.
One big disadvantage is money---it costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma(哮喘), and at times the air is so bad that I am afraid to go outside. Then there is the problem of travelling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.
Of course there are advantages. First, there is so much to do in the city, whatever your tastes in culture or entertainment. Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising---and, what is more, shops are often only a short walk away.
Is life better then, in the city? Perhaps it is, when you are in your teens(十几岁) or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem better. I certainly hope to move back there soon.
What was the writer always thinking about when he was a child?
A.Staying on the farm |
B.Moving to the countryside |

All boys and girls like good stories. I am sure that all children who read The Ugly Duckling will be glad to know something about the ‘King of Story Tellers’, who wrote it for them. Thousands and thousands of children have read this story, only to ask for it again and again. It has travelled the wide world over, and has been told in every country.
Hans Christian Andersen, the author of “The Ugly Duckling,” was born in Denmark. If you look on a map, you will see this little country in northern Europe. There, in the little village of Odense, he spent his boyhood. His father and mother were very poor. The family lived in two little rooms near the top of a house, where his father worked as a shoemaker.
On the roof was a box filled with earth. In this box his mother planted her vegetables. Little Hans loved to walk with his father in the woods, where he could pick wild flowers and hear the birds sing. His father read to him when his work was done, or told him stories. What his father did helped him open up a new world.
Once, when Hans was still a child, he went into a wheat field with his mother and a number of children, to pick the rest wheat which the reapers(收割机) had left in the field. While they were busy picking only a small amount of wheat for each of them, an angry bailiff(看守者) came rushing into the field, armed with a whip(鞭子). All ran, as fast as they could, away from the angry man. Little Hans was barefoot, and the sharp stalks(茎秆) of the wheat plants which had been cut down, cut his feet so that he could not get away.
Unafraid, the boy faced the angry man and his upraised whip. “How dare you hit me when you know God sees you?” he cried, looking fearlessly into the face of the angry bailiff. The whip came down, but not on little Hans. The bailiff admired the boy’s courage, and praised him for it. He sent him home with gifts, rather than punishments.
While Hans was still a boy, his kind father died. Then Hans and his mother were left alone, to care for each other.
“What will you do, Hans?” the mother asked “Would you like to become a tailor?”
“No, mother,” the boy answered; “I will go to Copenhagen and study. One day I shall write books.”
“But where will the money be found to pay your way?” asked the mother.
“I will work, and God will take care of me,” Hans replied.
So the boy left his native village and walked all the way to Copenhagen, which was very far.
What did Hans’ father do in the woods when the work was done?
A.He gathered wild flowers with Hans. |
B.He taught Hans to make shoes. |
C.He read books or told stories to Hans. |

Mark Twain is someone Americans are taught to love. Older relatives, English teachers and the media always praise him. But when you actually take the time to read The Adventures of Tom Sawyer, you find that his work is more wonderful than you could ever imagine.
The novel describes a young boy named Tom Sawyer growing up in a small town along the Mississippi River. He explores the countryside on a riverboat with his friends, falls in love with girls, starts secret clubs and searches for treasure. Twain’s idea of childhood is magical – a time of imagination, wonder and, of course, adventure.
More importantly, through the eyes of Tom Sawyer, Twain cleverly makes fun of US culture. For example, Tom hates going to church, and Twain uses scenes of Tom there to mock religion(宗教) and its old traditions.
Twain’s writing is full of these kinds of critical (批判的) points about culture and politics(政治). That’s why he is so loved in the US – he wasn’t afraid to state his opinions, and he did so clearly.
He also believed strongly in women’s right to vote in elections and gave a famous speech on the subject, called “Votes for Women”, in 1901.
“Tom was a great hero once more——the pet of the old, the envy of the young,” Twain writes in Tom Sawyer. But he could just as well be describing himself.
According to the writer, after reading The Adventures of Tom Sawyer, you are likely to think ______.
A.it’s not worth all the praise |
B.it’s as wonderful as you imagined |
C.it’s better to read it with teachers |
D.it’s even better than you imagined |

B.Where Twain’s idea of childhood comes from. |
C.How naughty and adventurous Tom Sawyer is. |
D.What makes Tom Sawyer’s adventures so wonderful. |
What does the underlined word “mock” mean?

Although most people believe that laughter is one of the nature’s great treatments for a whole range of mental and physical diseases, it is still a serious scientific subject that researchers are trying to figure out.
“Laughter above all else is a social thing,” says Baltimore neuroscientist(神经科学家), Robert Provine, who has studied laughter for many years. “All laughter groups laugh ‘ha-ha-ha’ basically the same way. Whether you speak Mandarin, French or English, everyone will understand laughter. There is a pattern generator(发生器) in our brain that produces this sound.”
Laughing is our first way of communicating. Babies laugh long before they speak. No one teaches them how to laugh. They just do. People may laugh at a prank(恶作剧) on April Fools’ Day. But surprisingly, only 10 to 15 percent of laughter is the result of someone making a joke. Laughter is mostly about social responses rather to a joke. Deaf people laugh without hearing and people on cell phones laugh without seeing, showing that laughter isn’t dependent on single sense but on social interactions.
And laughter is not just a people thing. Chimps tickle(挠痒) each other and even laugh when another chimp pretends to tickle them.
Jaak Panksepp, a Bowling Green University Psychology professor, studies rats that laugh when he tickles them. It turns out rats love to be tickled — they return again and again to the hands of researchers tickling them.
By studying rats, scientists can figure out what’s going on in the brain during laughter. Northwestern University biomedical engineering professor, Jeffrey Burgdorf has found that laughter in rats produces a chemical that acts as an antidepressant(抗抑郁药). He thinks the same thing probably happens in humans, too. This would give doctors a new chemical target to develop drugs that can fight depression.
Even so, laughter itself has not been proved to be the best medicine, experts said. Margaret Stuber, a professor at University of California, studied whether laugher helped patients. She found that distraction(分心) and mood improvement helped, but she could not find a benefit of laughter alone.
“No study has shown that laughter produces a direct health benefit,” Provine said, mainly because it’s hard to separate laughter from just feeling good. But he thinks it doesn’t really matter: “Isn’t the fact that laughter feels good when you do it enough?”
The underlined word “figure out” in Paragraph 6 means “________”.
A.deal with | B.work out |
C.look out of | D.come up with |
According to the passage, scientists studied rats in order to find ______.
A.how they laugh |
B.if they like laughing |
C.what laughter in rats produces |
D.how rats react while being tickled |
What can we know from Robert Provine’s research?
A.Laughter makes a person feel good. |
B.Laughter produces a direct health benefit. |
C.Laughter depends on all kinds of senses. |
D.Laughter is a way of communicating. |
What is probably the best title for this passage?
A.Why Rats Laugh |
B.When Laughter Happens |
C.How Laughter Works |
D.Why Laughter Matters |

A habit is any action that we have performed so often that it becomes something that we do almost without thinking. Some of them are thought to be bad habits. People spend countless hours and dollars each year trying to get rid of these bad habits but often fail. Why? Change is hard work and there is no shortcut to achieve it. However, there is still some advice for you to follow.
First, look at why you do it. In other words, what’s the result of doing this thing? If your bad habit is shouting at people when you are unhappy or under pressure, what do you get from it?

Next, take a look on the other hand. What are you losing because of your habit? Shouting at other people is a bad habit because it makes people around you feel bad and unhappy. Leaving your homework undone is a bad habit because you may be punished by your teacher. Having more Internet time means that you are losing the chance to learn the things that you need to learn.
