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(大寫字母) 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.

“I had a Welsh speaking test. I'd had to memorize a paragraph in front of the whole class. I just couldn’t do it,” says 13-year-old Mary. “I pretended to be ill.” But Mary did not enjoy her day off. “I watched TV all day — it was boring. I wished I had gone to school.”
Mary’s story is not unusual in Britain. According to the latest government figures, pupil absences are rising, despite schools taking a hard line on truancy (逃學)．
Philippa James, a PhD researcher at Cardiff University’s school of social sciences, thinks she knows why: “The more schools improve methods of detection（檢查）, the more children work out better methods of deception.” Teenagers told her it was now harder to skip a single lesson, so they’d miss whole days to avoid being caught.
For several years, James has researched student truancy of 60 teenagers, aged 13 and 14, including Mary, to see how the teenagers truant, for how long, and why.
Through online conversations and face-to-face interviews, she discovered that most truancy was “a response to factors within the school”. Truants are not necessarily less advanced or less intelligent. They complained of teachers who failed to engage them, and of “boring” lessons. “Many truants really enjoy school and believe in education, but drop out when aspects of it were ineffective.” James says.
The views of students like Adam, who believes that skipping lessons has little impact on his schooling, were common. “I only take-off for a lesson, or a couple of days. It doesn’t affect my education,” he told James.
James’ study concludes that schools need to address the question of why pupils want to leave in the first place. “Pupils need help from the start.” she says. “It’s a two-way process – schools must be responsive. We need to look at the reasons for truancy rather than the number, so that instead of walking away from school, students have the skills and chances to talk through problems and make a change.”
小題1:What is one of the reasons for school truancy according to James’ study?
A．Truants are fallen behind in their studies.
B．Truants have no interest in school subjects.
C．Truants have more interesting things to do.
D．Truants are not satisfied with the teachers.
小題2:The underlined phrase “taking a hard line” (paragraph 2) is closest in meaning to“        ”.
A．experiencing a problem withB．having a strict attitude towards
C．finding it difficult to solveD．having little success with
小題3: By citing Adam's remark, James wants to show that      .
A．school education is not efficient and needs improvement
B．it’s a popular belief that occasional truancy won't cause much harm
C．school truancy is becoming more serious and needs more concern
D．even good students may sometimes need a break from school
小題4: What is Philippa James’ suggestion to schools?
A．Schools should solve the problem of teachers.
B．Schools should be more active in helping beginner truants.
C．Schools should have a better control of hidden truants.
D．Schools should find out who truant and how they it.

Smartphone ,poor sight
Look around and you’ll see people busy on their smartphones. Smartphones do make our lives easier . But have you ever thought about what they mean to you eyes?
According to a study ,half of British people own smartphones and they spend an average of two hours a day using them . There has been a 35% increase in the number of people in the UK who suffer from shortsightedness since smartphones were introduced there in 1997.
Staring at smartphones for long time gives you dry eyes. When looking at something in the distance ,your eyes automatically blink a certain number of times. However ,when you look at things closer  to your face ,the blinking slows down . This reduces the amount of tears and causes discomfort in your eyes. Another bad habit is using  smartphones in dark rooms before going to sleep . If you look at a bright screen while your pupils become larger ,too much light enters your eyes. This can do harm to the eyes and cause a disease called glaucoma.
While you’re probably not going to stop using to your smartphone,there are a few things you can do to protect your eyes. Hold  your phone at least 30 continues away from your eyes when using it. Take a break every hour and try the following :look at something at least five meters from you and then focus on the tip of your nose. Repeat this several times. It should reduce the discomfort in your eyes.

In the most southern part of our planet, there’s a place that’s covered with snow and ice all year round. But it has the clearest and cleanest air. Amazingly, in this place, the sun sometimes hangs even in the midnight sky. This place is Antarctica (南極洲): the coldest, windiest and harshest (惡劣的) place on the Earth.

As the world’s least-known place, Antarctica is of great interest to scientists around the world. In 1983, China joined the Antarctic Treaty (《南極條約》). The treaty made Antarctica a peaceful place for member countries to do scientific research. During 30 years, China has sent many scientists to Antarctica. They mostly look at the resources under the icy land and do research about climate change and marine (海洋的) biology.
Antarctica is a place with fantastic views. However, life there is very hard. Food is one of the biggest problems. Frozen (速凍) food which can be heated easily is people’s daily food. Fresh vegetables are hard to grow in the cold weather. Therefore, scientists often eat dried or canned vegetables.
Sleep is also troublesome. In Antarctica, summer lasts from November to March. During this period, Antarctica points to the sun and receives sunlight 24 hours a day. In order to get some sleep, scientists cover the windows with black plastic cloth to create “night”.
Working in Antarctica is dangerous, especially when meeting gale-force (七級以上的) winds. Sometimes the wind is even stronger than a typhoon. It can easily blow people away. So there are ropes that connect buildings of some research stations. People can hold these ropes to keep their balance in forceful winds.
What’s more, communicating with others is difficult. Without cables and Internet in some research stations, two-way radios are the only tools to communicate. If people want to say hello to friends and relatives, they can use satellite phones.
Although it is challenging to work in Antarctica, scientists’ passion to learn about this mysterious land will never end. It is hopeful that one day they will step every corner of this icy land.
小題1:From Paragraph 1, we learn that the Antarctica ______.
A．is covered with snow and ice
B．rains heavily from time to time
C．has little wind most of the time
D．has sunshine during every night
小題2:Scientists from China go to Antarctica to _____.
A．find out ways to control water pollution
B．research climate change and marine biology
C．grow plants and vegetables in special condition
D．stop the hunters from killing the marine biology
小題3:In order to sleep well in Antarctica, the scientists have to _____.
A．wear more clothes to keep warm
B．cover the windows with black cloth
C．connect research stations with ropes
D．eat more fried and canned vegetables
小題4:We can replace (替換) the underlined word passion in the last paragraph with       .
A．strong love
B．full preparation
C．pleasant introduction
D．amazing imagination
小題5:The passage is mainly about       .
A．view of the Antarctica
B．exploring the Antarctica
C．how to survive in the Antarctica
