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 (喷) 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 (树脂)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?

A 70-year study of personality suggests that pessimism is a risk factor for early death, especially among men.
The study results also indicate that pessimism can be linked to increased risk for sudden death from accidents or violence, according to the report published in the March issue of Psychological Science.
Christopher Peterson of the University of Michigan and his colleagues analyzed data from the Terman Life-Cycle Study, which began by studying California public-school children with high IQs in 1921 and followed them through their life. Most of the 1,528 children were teenagers when the study began. Those still living are now in their 80s. In 1936 and 1940, participants were asked to complete a questionnaire designed to obtain information about difficult life events and their effect on overall outlook. One such question was, “What do you regard as your most serious fault of personality or character?”
Pessimists were defined as fatalistic(宿命论的)people who tend to blame themselves when things go wrong and who believe that one bad event can ruin the rest of their life. They also tend to expect bad things to happen to them and feel that they have little or no ability to change their situation.
Males were more likely than females to be classified as pessimistic. Compared with individuals with a more cheerful and optimistic outlook, pessimists were more likely to die from accidents and violence (including suicide).
A pessimistic personality may lead to poor problem-solving ability, social difficulties and risky decision-making. Taken together, these variables put the pessimist at higher risk of untimely(不适时的) death, say the researchers. Such a person is less likely to avoid or escape potentially dangerous situations, the researchers concluded. “A pessimistic way of thinking in which people worry too much about bad events, predicts untimely death decades later,” according to Peterson.
小题1:According to the passage, you may be a pessimistic person, if one failure makes you feel________.| A．other people have been unfair to you. | | B．other people will help you. | | C．you cannot change a bad situation. | | D．you can do better next time. |
小题2:According to the passage, pessimists may feel all of the following EXCEPT________| A．helpless when faced with difficulties. | | B．cheerful when faced with troubles. | | C．hopeless when one bad event occurs. | | D．guilty when things go wrong. |
小题3:Which of the following statements is true, according to the passage?| A．Pessimists believe that everything in life depends on fate. | | B．There are more pessimists among women than among men. | | C．Most pessimists will end up committing suicide. | | D．All pessimists will eventually die from accidents. |
小题4:The Terman Life-Cycle Study is a research program that studies________.| A．people over 70 years old. | | B．people since their childhood. | | C．pessimistic people over 80 years old. | | D．only younger people. |
小题5:The analysis made by Christopher Peterson and his colleagues shows that pessimistic people________| A．will die from violence if they learn to be optimistic. | | B．will more likely die from violence than optimistic people. | | C．will die from violence because their IQs are low. | | D．will die untimely if they are not able to learn to be cheerful and optimistic. |

[1] Many good reasons for parents to send their children to camps.
[2]When children go to camp, they are on their own, sometimes for the very first time in their lives. They have to decide what to wear, what to eat and which activities to participate in. As a result they develop confidence and independence.
[3]As self-respect develops from learning to be on their own, children continue to try new activities. Also it is possible that they will engage in what they are unfamiliar with. In school, children do not experience success in the same way. Camp can be a school without failure because just having fun makes them a success.
[4]One of the greatest benefits of a camp experience is that children develop social skills. In a camp setting, a good counselor will make sure that every camper is included in the activity and that each child interacts with the others in a positive way. They learn to give and take, and they learn how to work and cooperate. Something as simple as clean-up, is not only there to get the cabin clean, but to promote a team atmosphere of working together which in turn results in friendship.
[5]The obvious benefit of camp is that campers make long lasting friendships. These friendships can often be unique and special because campers are living with each other and see the true personalities. Children learn to see others from a different viewpoint. Children tend to be accepted for who they are and do not have to be concerned about what they wear, what they are good at and how they look. This is because in a camp setting, respect and caring finally win out over materialistic objectives.
[6]In a word, camp does give children fun, friends and fulfillment.

Dust storms are violent and mostly unpredictable. They can cause property damage, injuries, and deaths, so it’s necessary to know what to do when you come across them.
Watch out for dust storm warnings. Dust storms are most likely to occur on hot summer days, so listen to the local TV or radio broadcasts before traveling in hot, dry conditions, and consider changing or giving up your trip if dust storms are predicted. Roadside signs may also be able to warn you of dust storm danger.
Be prepared. If you are in a storm-prone area, carry a mask(口罩) to keep out small dust particles (颗粒), and take eye protection to protect your eyes. A supply of water is also necessary.
Go beyond the storm. If you see a dust storm from some distance, and you are in a vehicle, you should try to escape from it. Some dust storms can travel at more than 75 miles per hour, but they frequently travel much slower. However, it is not advisable to put yourself at risk by driving at high speed.
Stay inside. Do not move about in a storm, as you will not be able to see hidden risks in your path. So if you’re in a house, stay inside.
Protect yourself from flying objects. Cover as much of your body as possible. A dust storm’s high wind can carry heavy objects. If you find yourself without shelter, try to stay low, close to the ground, and protect your head with your arms, a backpack or a pillow.
小题1:What does the underlined sentence in Paragraph 4 mean?
A．Dust storms usually travel much slower than vehicles.
| B．Don’t be so worried about dust storms in the distance.
| C．You shouldn’t drive at a risky speed to escape from dust storms.
| D．Driving faster than the dust storm is the most important thing. |

Words can hurt
I remember the pain most vividly. My stomach was sick, my heart hurt, and my eyes stung(刺痛的) from holding back tears.
“you know, Autumn,” my friend Nick said, “Lisa and Andrea were just talking about you.” I immediately got nervous. “They said that the only reason you start on the basketball team is because the coach （教练）likes you .It’s not because you’re good.” I might be sick. “They said they’re tired of you always getting what you want.”
I struggled to keep myself from crying, sinking（下沉） to my knees on the cold floor. After Nick told me everything my supposed best friends said about me, I was hurt.
Lisa and Andrea came in from lunch break acting as if nothing had happened . Lisa was still my deskmate, and Andrea was still my partner for our history project.
I was amazed at their ability to pretend we had the perfect friendship, especially since they’d said such hurtful things.
I was a freshman in high school, and I felt like I didn’t have a friend in the world, all because of a rumor（谣言）.
The tongue can be our worst enemy. Rumors harm confidence（信心） and separate close friends. They are like sharp knives, cutting one’s dignity（尊严） into pieces. When we say unkind things about others, we’re thrusting(插) knives into their hearts.
So how was I to act next? When Lisa and Andrea pretended our friendship hadn’t changed, I thought of attacking them back. But instead, I told them directly that they had hurt me. Lisa started crying and Andrea was speechless. I know they were both sorry for what they had said. They apologized, and I forgave them with grace(优雅). Sure, things were a little awkward(尴尬) at first, but soon enough everything was back to the way it had been before.
I still deal with gossip（流言）, sometimes as a recipient（接受者） and sometimes as a participant（参与者）. But the more I learn about love, the more I realize the importance of encouraging others- sometimes gossip never does.

How Do Animals Catch their ZZZ"s（打鼾声）？
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．
小题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． |
小题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． |
小题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． |
小题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 |
