Skiping classes violates school rules and a poor attendance record will damage your final mark. But some college students still try every means to escape classes.   The number of these rebels may be much bigger than you think.  Three students from Anhui Normal University established Itaoke. Com in June. The website quickly attracted 2 000 registered members in three months. On the website, students share their experiences of skipping classes and even post ads to look for someone to stand in for them to attend courses.  Its embarrassing for universities to see this shameful behavior discussed:
However，it's good for schools and teachers to know via the website the reasons why students skip classes，according to Professor Xiao Haitao from Shenzhen University: Xao pointed out that some`students skip classes because of laziness.Others play truant because the teaching is truly dissatisfactory,“Universities can seek improvements to give a cure to the class-skipping problem，”said Xiao.
Chen Yang，21，thinks that he is  “forced" to skip some courses because of the poor teaching.  the  senior，majoring in English at Yangtze University, thinks that he's wasting time in the classroom when the teacher reads the textbook word for word or hands him outdated reading materials. He would rather skip classes to study in the library, watch online videos of Harvard or Yale lectures，or sit in on(旁聽）other courses he is interested in. Chen draws a clear line between himself and those who skip classes in order to get more sleep or fool around on campus. He emphasized：“I skip classes with a clear goal，which is to probe into areas I'm interested in and broaden my horizons.”
Li Sicen，President of the National Taiwan University，seems to be on Chen's side.  Li claimed that he supported those students who skip classes for good reasons.
However，Professor Xiao warns students that Li is not giving permission for students to skip  classes. Xiao suggests that Li was just showing his understanding of truancy in a limited number of cases.
In Professor Pan Cuiqiong's opinion，students tend to jump to the conclusion that a certain course is boring and useless. "To clear students' misunderstanding，teachers should use materials closely related to students’lives and adapt interactive teaching methods，”said Pan.
Besides offering teachers more training，schools also need to give students different optional courses and ensure that they can attend the courses they are interested in，according to  Professor  Xiao.  Many Chinese students have the experience of being kicked out of an optional course because its size is limited. They are then forced to choose courses they dislike and are likely to skip them. We may learn from Sydney University in Australia.  There aren't any problems with numbers---if a course is popular then there will be more than one class per week.

Cheektowage Central Middle School can be a lot of fun. It has game nights and student dances, after-school activities, and sports teams. However, students at the school must earn the right to join in the fun. If they don’t do their homework, participate in class, and behave at all times, they’re banned(禁止) from participating in after-school activities.
Students and parents say the threat of being excluded(排除在外) appears to be working. Kenny T. of Reno, Nev., says it taught him that actions have consequences: “I learned that I need to be balanced in both my work and athletics to be rewarded for working hard.” Parent Sondra LaMacchia told The New York Times that her 14-year-old daughter is learning responsibility at Cheektowaga Central. The teen used to perform poorly in her studies, but then she was banned from a school dance. The message got through loud and clear. “It’s nobody’s fault but hers,” LaMacchia said.
Although exclusion may help teach responsibility, some psychologists say it can also be threatening, especially for students who often cause, or may cause, trouble in school. They might become more aggressive and antisocial, which is exactly what schools like Cheektowaga Central want to prevent.
Should schools exclude students from activities to get them to behave? I believe teens need school activities and that inclusion can be the answer. For some troubled students, activities can be their motivation to stay in school. “Activities such as sports may be the only thing keeping certain students in school,” says Duace Wood, a teacher at Mohonasen High School in Rotterdam, N.Y. Getting involved in after-class activities keeps troublesome students in class. Even if they don’t do as well as their classmates, they are still learning. The more time they spend at school, the less time they have to even think about starting trouble. Teams also provide support and role models, and they help build the confidence that students need to succeed. If students who don’t behave are banned from activities, they might give up on school altogether.
小題1:Paragraph 2 is developed by _______.
A．analyzing causesB．giving examples
C．examining differencesD．following the time order
小題2:Parent Sondra LaMacchia supports the policy of exclusion because _______.
A．it provides role models
B．her daughter is aggressive
C．her daughter hates taking exercise
D． it helps teach responsibility
小題3:In Paragraph 3 and 4, the author mainly talks about________.
A．students who are good at sports
B．students who often cause trouble
C．teens who do well in their studies
D．teens who always behave themselves
小題4:What is the author’s attitude towards the school’s policy of exclusion?
A． NegativeB．SympatheticC．SatisfiedD．Supportive

Sharks have lived in the oceans for over 450 million years, long before dinosaurs appeared. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely.
Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which sells for as much as $50 a bowl in fine Hong Kong restaurants. Other sharks are killed for sport and out of fear. Sharks are vulnerable(易受傷的) to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring（后代）.
Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of shark injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine（海洋的） mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits.
If you are a typical ocean-goer, your chances of being killed by an unprovoked（非受挑釁而發生的）attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than a shark and thousands of times more likely to get killed when you drive a car.
Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria, and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.
Sharks are among the few animals in the world that almost never get cancer and eye cataracts（白內障）. Understanding why can help us improve human health. Chemicals taken from shark cartilage（軟骨）have killed cancerous tumors in laboratory animals, research that someday could help prolong your life.
Sharks are needed in the world’s ocean ecosystems. Although they don’t need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.
小題1:Which of the following is NOT a reason why people kill sharks?
A．People kill sharks for food.
B．People kill sharks for sport.
C．People kill sharks out of fear.
D．People kill sharks because they often attack swimmers.
小題2:According to the passage, which of the following statements is NOT true?
A．There are many different species of sharks, but only a few of them are dangerous to humans.
B．Sharks never get ill.
C．Sharks are a valuable resource for human.
D．Sharks play an important role in the ocean ecosystem.
小題3:It can be inferred from the passage that _______.
A．movies have given people the wrong impression of sharks
B．most sharks are dangerous to humans
C．sharks will attack anyone who is wearing black
D．it is dangerous to swim in the ocean
小題4:The underlined word “prolong” in the last but one paragraph means ______.
A．saveB．protectC．lengthenD．improve
小題5:The best title for the passage would be _______.
A．Are Sharks Dangerous?B．Sharks And Humans
C．Sharks: Humans’ FriendsD．Sharks Help Save Human Lives

The earth is not the only body that travels around the sun. With it are eight other planets, fellow members of the sun’s family.
Two of them, Mercury (水星) and Venus, are nearer while the other six, namely Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, also in their given order from the sun, are farther from the sun than the earth is. The farther they are, the longer trips they make around the sun. People noticed long ago that these traveling bodies moved around in the sky in definite paths. It is a force called gravity that holds them in their paths.
We know that every little bit of matter in the universe pulls upon every other bit of matter. The pull between two bodies is proportional (成比例的) to the product of their masses. Because the sun is so large the pull between the sun and the planets are thus great. If it were not for this pull, the planets would fly off into space. In the same way there exists a pull between the earth and the moon, which keeps the moon traveling in its orbit around our planet, the earth. Gravity holds you to its surface, and pulls back to it the ball which you throw into the air. Of course the ball also pulls on the larger earth but the earth is so much larger that the pull is not noticed.
Now remember that large bodies exert a greater pull than smaller ones which contain less material. But each object in the universe, no matter how small, pulls on all other objects to some degree.
小題1:There are ________ that travel around the sun in the sun’s family.
A．nine planetsB．eight planets
C．one star and ten planetsD．the earth and the sun
小題2:Which two planets make the longest trips around the sun among all the planets in the solar system?
A．Mercury and Venus.B．Neptune and Pluto.
C．Saturn and Uranus.D．Mars and Jupiter.
小題3:From the passage we can see__________
A．all the objects, big or small, must exert the same pull on one another
B．large objects exert the same pull on anybody as small objects
C．small objects exert the same on large ones
D．each object in the universe exerts a pull on all other objects
小題4:From the sentence “The pull between two bodies is proportional to the product of their masses.” We can infer that the pull between__________
A．the sun and the moon is greater than between the sun and the earth
B．the earth and the moon is greater than that between the sun and the earth
C．the sun and the earth is greater than that between the earth and the moon
D．the sun and the earth is the same as that between the earth and the moon

Scientists would like to place a huge mirror in space above the earth. It might be sixty miles wide. It would be used to catch the rays (光線) of the sun. It would direct the sun’s rays upon the earth as a child might do to make sunlight dance on the wall with a hand mirror.
Why do they want to do this? The sun’s rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts (霜凍) which might come at night and hurt fruit crops. They could melt (融化) dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed.
小題1:The huge mirror would ______.
A．stand 60 miles in height (高度) B．be 60 miles from side to side
C．cover 60 miles of the earth D．be 60 miles above the earth
小題2:The mirror would be used to ______.
A．reflect (反射) sunlightB．absorb (吸收) sunlight
C．see what the earth looks like D．see how clouds move
小題3:The strong light from the mirror could possibly ______.
A．hurt fruit cropsB．set fire to cities
C．bring longer daytimeD．shine through walls
小題4:The huge mirror is ______.
A．something in a story B．already made
C．just an ideaD．to be made soon

How Do Animals Catch their ZZZ's（打鼾聲）？
Different creatures have developed some pretty creative ways to get their rest and stay safe． The lizard likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest． If a snake tries to slither up the branch to eat it, it will shake the branch and knock the lizard off, and the lizard will fall safely into the water． Chameleons can change color to match their surroundings in order to hide even while sleeping．
Gorillas like to sleep high in the trees． They build a new bed every night, sometimes taking up to half an hour to pile branches, twigs, and leaves into a comfortable bed． Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks, they don't use a nest． They just lock their feet around a branch and hang on． A special tendon in their legs is automatically tight when they are at rest, so they won't let go and fall．
Dolphins live underwater, but must come to the surface to breathe． Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing． Seals also do this, lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface． Some ducks may also have this ability, and actually sleep with one eye closed and one eye open．
小題1:How does a chameleon protect itself while sleeping?
A．By changing its body colors
B．By hanging out over a pond．
C．By sleeping with half their brain．
D．By making beds with branches．
小題2:Why will not birds fall when they are at rest?
A．They build nests and sleep in them．
B．They fall asleep automatically．
C．They have a loose tendon in their legs．
D．They lock their feet around a branch．
小題3:How do dolphins breathe?
A．They breathe underwater．
B．They come to the surface to breathe．
C．They breathe underwater or come to the surface to breathe．
D．We don't know．
小題4:What does the writer intend to tell us?
A．The cleverest animal is the gorilla because it can make beds．
B．Differences in habitat can lead to different living habits．
C．The ways animals catch their ZZZ's are pretty much the same．

Scientists from South Korea are trying to convert（轉化）sound waves into electricity. The research could lead to charging a cell phone from a conversation or providing energy to the nation’s electricity system generated（產生）by the noise during rash-hour traffic.
“Just as speakers transform electrical signals into sound, the opposite process —turning sound into a source of electrical power — is possible,” said Young Jun Park and Sang-Woo Kim, the joint authors of a new article in the journal Advanced Materials.
Harvesting energy from phone calls and passing cars is based on materials known as piezoelectrics. When bent, piezoelectric materials turn that mechanical energy into electricity. Lots of materials are piezoelectric: cane sugar, quartz （石英）and even dried bone which could create an electrical charge when stressed. For decades, scientists have pumped electricity into piezoelectric materials for use in environmental sensors, speakers and other devices.
Over the past few years, however, scientists have made dramatic advances in getting electricity out of piezoelectric devices. In an experiment, by using sound waves, which at 100 decibels（分貝）were not quite as loud as a rock concert （a normal conversation is about 60-70 decibels）, the South Korean scientists produced a mild electrical current of about 50 millivolts（毫伏）. The average cell phone requires a few volts to function, several times the power this technology can currently produce.
“But the real question is whether there is enough surrounding noise to act as a power source as for a cell phone,” said McAlpine, a leading scientist. A consumer probably wouldn’t want to attend a rock concert or stand next to a passing train to charge his cell phone. The South Korean scientists agree but they expect to get a higher power output as they continue their work.
小題1:According to the two South Korean scientists, ________.
A．sound waves can travel faster than electricity
B．new materials can send cell phone signals better
C．using cell phones adds to heavy traffic in rush hour
D．electricity and sound can be transformed into each other
小題2:We know from the passage that piezoelectric materials ________.
A．can produce electricity when stressed
B．are good at changing electricity into sound
C．can reduce the noise of passing cars
D．have been widely used in phones and cars
小題3:It can be inferred from the South Korean scientists’ experiment that ________.
A．it is hard to change sound into electricity under current conditions
B．it is impossible to make use of loud sound
C．the technology has a long way to go to have a practical use
D．the technology can power cell phones easily
小題4:What McAlpine doubts about the technology is ________.
A．the noise pollutionB．the sound resource
C．the cost of piezoelectricsD．the safety of devices
