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．
D．In order to protect themselves most animals choose not to sleep

Scientists in Colombia have trained a team of rats to help remove land mines from the countryside. Land mines are small bombs hidden in the ground and designed to explode(爆炸) when someone steps on them.
When trained, the rats can smell special metals in the mines and then signal(發(fā)信號(hào)) to their human team. Then why use rats for such an important job?
In the past, dogs have been used to find bombs. Rats have a good sense of smell and can respond to orders, just like dogs do. But rats are much lighter than dogs. They stand less of a chance of setting off the mines, which explode under a certain amount of weight. What’s more, the best rats are cheaper to keep than dogs. It costs about the same amount of money to take care of one dog as it does 70 rats.
The rats have already been used in Tanzania, an African country with many land mines. Luisa Fernanda Méndez and her team in Colombia are training the even lighter Wistar rats. These are the white rats with red eyes that scientists often use in laboratory experiments. “They even train their babies to perform their jobs, which saves us a lot of time, ” Méndez said.
Colombia has the second-highest rate(比率) of deaths from land mine accidents in the world. Last year, land mines killed 695 people — 56 of whom were children. A criminal group called the Revolutionary Armed Forces of Colombia, or FARC, as well as other organizations, have placed the mines. FARC are strongly against Colombia’s government. The group has placed mines all around its own bases and in many places in the countryside.
In the past, the Colombian government hired peasants and poor farmers to find mines. Many of them died trying to find the well-hidden bombs.
Colombian police official Erick Guzmán hopes the team of rats can come to the rescue(援救). “These rats will be a great help,” he said.
小題1:How do rats help to find land mines?
A．By their special sight. B．By their light weight.
C．By their sense of smell.D．By their excellent hearing.
小題2:The advantage of rats over dogs in finding bombs is that _____.
A．they are cleverer.
B．they run faster
C．they have a better sense of smell
D．they don’t make mines explode as easily
小題3:The underlined word “They” may refer to ______.
A．scientistsB．Wistar rats
C．dogsD．Méndez and her team
小題4: What is the passage mainly about?
A．Specially-trained rats help clear land mines.
B．People in Tanzania are suffering from land mines.
C．Dogs are no longer used to find land mines.
D．Land mines have become a great danger to Colombians.

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.
小題1:The underlined word“rebels" in Paragraph 1 refers to           
A．students who embarrass their universities
B．students who establish websites
C．students who skip classes
D．students who quarrel with their parents
小題2:Chen Yang Skips some courses because_       ___.
A．his school is more student-centered
B．he wants to get more sleep
C．he wants to fool around on campus
D．the teaching style needs much improvement
小題3:According to the passage，we learn that Professor Xiao__     __.
A．is giving permission for students to skip classes
B．thinks it's embarrassing for the three students to establish ltaoke. com
C．thinks the website will help to know why students skip classes
D．claimed that he supported those students who skip classes for good reasons
小題4:Which of the following measures is NOT mentioned to stop students skipping classes?
A．Teachers should adopt practical materials and flexible teaching methods.
B．Schools should offer teachers more training:
C．Schools need to ensure that students can attend various courses they are interested in.
D．Students should be punished if they skip classes.

Last year, on report card day, my son and a group of his 13-year-old friends piled into the back seat of my car, ready for the last-day-of-school party at McDonald's. “Jack got a laptop for getting straight A's, and Laurie got a cell-phone,” one boy said. “Oh, yeah, and Sarah got an iPod Nano, and she's only in third grade,” said another. “And how about Brian? He got $10 for each A.”
I suddenly became concerned. These payoffs might get parents through grammar school, but what about high school and beyond? What would be left after the electric guitar, the cell-phone, and the DVD player?       
I saw the road ahead: As the homework load increased, my income would decrease. I saw my comfortable lifestyle disappear before my eyes---no more of those $5 bags of already-peeled organic（施有機(jī)肥料的）carrots. No more organic anything!            
I started to feel surprised and nervous. Would every goal achieved by my two children fetch a reward? A high grade point average? A good class ranking? Would sports achievements be included in this reward system: soccer goals, touchdowns（橄欖球底線得分）? What about the orchestra（管弦樂隊(duì)）? Would first chair pay more than second? I'd be penniless by eighth-grade graduation.
“We never paid anything for good grades,” said my neighbor across the street, whose son was recently accepted at MIT. “He just did it on his own. Maybe once in a while we went out for pizza, but that's about it.”
Don't you just hate that? We're all running around looking for the MP3 player with the most updates, and she’s spending a few dollars on pizza. She gets motivation; we get negotiation. And what about the primary grades? What do these students get? “When the teacher asked if anyone got rewards for good grades, everyone in my class raised their hands and said they got ice cream cones (蛋卷),” said one third-grader.
小題1:What's the best title for the passage?
A．Tips on Paying Kids for Good Grades
B．New Trends in Paying Kids for Good Grades
C．Good Grades Mean Good Rewards
D．Don't Pay Kids for Good Grades
小題2:What does the underlined sentence in the third paragraph probably mean?
A．Taking care of my children would influence my work.
B．I would spend less money on my children's good grades.
C．More rewards would be needed as my children grow up.
D．Reducing my children's homework load would cost me a lot.
小題3:It can be inferred from the passage that ________. 
A．if you buy children pizza as a reward, they will work harder
B．if you pay kids for good grades, they will take it for granted
C．children will not ask for rewards when they enter high school
D．good grades won't help kids make great progress in the future
小題4:The author takes her neighbor as an example to show _______.
A．pizza is the best way to motivate children
B．it is necessary to reward children for their good grades.
C．getting rewards for good grades is common nowadays
D．rewards are not the only way to motivate children

SEE a cell phone cover that you like on Taobao? Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, you'll be able to get it in minutes just by hit­ting "print" on your computer.
You might find it hard to believe that you could actually "print" an object like you would a picture. But it is not that hard to under­stand how it would work. Just as a traditional printer sprays (噴) ink onto paper line by line, modern 3-D printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.
Instead of ink, the materials the 3-D printer uses are mainly plastic, resin (樹脂)and certain metals. The thinner each layer is --- from a millimeter to less than the width of a hair ---  the smoother and finer the object will be.
This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.
Last year, though, saw a big change in the 3-D printing industry--- printers became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost £20,000 (200,000 yuan), while now they cost only about £ 1,000, according to the BBC.
Taken out of the factory and in­troduced to more diverse and com­mon uses, 3-D printing can create just about anything you can think of ---flutes (笛子), bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell Univer­sity in New York have just made an artificial ear using a 3-D printer, accord­ing to Science Daily. The fake ear looks and acts exactly like a natural one.
However, as 3-D printing becomes more commonplace, it may bring about certain problems --- such as piracy. "Once you can download a coffee maker, or print out a new set of kitchen utensils (餐具) on your personal 3-D printer, who will visit a retail (零售的) store again?" an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the world could use a 3-D printer to print out a fully functioning gun?
小題1:According to the article, in the future, the 3-D printing technology will ___.
A．enable people to make better purchases online
B．be applied as widely in our daily lives as computers
C．change the way we make many products
D．shorten the time it takes for people to get what they buy online
小題2:What was the big event happening in the 3-D printing industry last year?
A．The 3-D printing technology was taken out ofthe factory.
B．The 3-D printer became more affordable forconsumers.
C．The 3-D printer was used for medical treatmentfor the first time.
D．3-D printing technology began to be used invarious fields.
小題3:How is the last paragraph developed?
A．By analyzing a cause and an effect.B．By making comparisons.
C．By giving examples.D．By presenting research findings.
小題4:What is the best title of the passage?
A．Printing out everythingB．Technology in the future

"USA? Britain? Which country is better to study in?" We often hear such discussions. As China opens its doors, studying abroad has become a dream for many Chinese students. They want to learn about the world.
It's true that studying abroad can help students develop themselves. Language skills will improve and it may be easier to find jobs.

It’s not easy being a teenager---nor is it easy being the parent of a teenager. You can make your child feel angry, hurt, or misunderstood by what you say without realizing it yourself. It is important to give your child the space he needs to grow while gently letting him know that you’ll still be there for him when he needs you.
Expect a lot from your child, just not everything. Except for health and safety problems, such as drug use or careless driving; consider everything else open to discussion. If your child is unwilling to discuss something, don’t insist he tell you what’s on his mind. The more you insist, the more likely that he’ll refuse to talk. Instead, let him attempt to solve things by himself. At the same time, remind him that you’re always there for him should he seek advice or help. Show respect for your teenager’s privacy(隱私). Never read him his mail or listen in on personal conversions.
Teach your teenager that the family phone is for the whole family. If your child talks on the family’s telephone for too long, tell him he can talk for 15 minutes, but then he must stay off the phone for at least an equal period of time. This not only frees up the line so that other family members can make and receive calls, but teaches your teenager moderation (節(jié)制). Or if you are open to the idea, allow your teenager his own phone that he pays for with his own pocket money or a part-time job.
小題1:Why is it not easy being a teenager or a parent of a teenager?
A．Because the teenager is very naughty.
B．Because the parent always expects a lot from the child.
C．Because you can make your child feel hurt, or misunderstood by what you say without realizing it yourself.
D．Because the teenager wants his or her own space.
小題2:The main purpose of the text is to tell parents       .
A．how to get along with a teenager B．how to respect a teenager
C．how to understand a teenagerD．how to help a teenager grow up
小題3:The last paragraph is about how to teach a teenager        .
A．to use the phone in a sensible wayB．to pay for his own telephone
C．to share the phone quicklyD．to answer the phone quickly
小題4:What should parents do in raising a teenager according to the text?
