Imagine this: you get up in the morning and put on a custom printed T-shirt. Then you eat some 3-D printed food and relax on your printed sofa. Perhaps you take a ride in a printed electric car to the hospital to get a printed tooth fitted.

Though some of these things may seem impossible, they’re closer to reality than you might think. The world of 3-D printing is coming to a store near you soon.

The idea of 3-D printing is to produce complicated shapes in a very personalized way. If you want to make a totally new object, you need to make a virtual design in a CAD（computer aided design）file first. Or you can use a 3-D scanner to make a digital copy of an object. Then, based on the design or copy, the 3-D printer makes paper-thin slices out of liquid, plastic, or metal and puts them together to create the object you want.

There are many areas in which 3-D printing can change our lives. One such area is health care. Researchers have developed simple 3-D printed organs, which can be used in life-saving operations. A 17-year-old boy in the US has also recently developed a brain-powered, 3-D printed replacement hand. From heart monitors to fake limbs（四肢）, we can soon be living longer thanks to 3-D printed technology.

Another area that 3-D technology looks sure to change is food. Can you imagine being able to print your favorite dishes at home at the touch of a button? Even big companies are behind the trend. Hersheys, one of the largest chocolate makers in the world, recently announced that it would start producing chocolate with the help of 3-D printers. NASA, the US space agency, has reportedly spent $125,000 （767,594 yuan） developing a “3-D pizza printer”.

It is not yet clear how long it will take until 3-D printers are available to everyone. But one thing is for sure: the possibilities are endless.

1.The purpose of the first paragraph is to ________.

A. list some major 3-D printing breakthroughs

On Christmas morning, Linda wakes up, and tries to imagine the wide-eyed surprise of children in another household as they unwrap the presents she carefully chose for them. Linda has never met the children, but that’s all part of the joy of giving as secret Santas, she says.

"It's an amazing feeling to buy gifts on an anonymous (匿名的) basis," says Linda.

"It brings a whole new meaning to the holidays."

Linda and Tony are an American couple living in Toronto, Canada, and Linda did charitable work as a member of the American Women's Club of Toronto. As the name suggests, members are U.S. citizens living in Toronto, who join together for fellowship and community service.

To find her "adopted" family, Linda goes to the local schools and requests a wish list for a family that's struggling to survive. Last year she helped a single mother with three children. The mother works as a cleaning lady in a nursing home.

"The list is always heartbreaking. They have an opportunity to ask for anything and do just the opposite, asking for basic clothes or simple toys," she says. "We always buy the kids a new winter coat, hats, and gloves." She also buys gifts for the parents.

Last year Linda asked the mother for a second wish list--one that didn't include the basics. "Every child should have a Christmas that sticks with them for a lifetime." She purchased iPods for the two older children and a video game system for the youngest."I have learned a very valuable lesson in all of this," says Linda. "Pay attention to what's going on in your own backyard--no matter where you live."

The joy of giving as secret Santas is much sweeter when the gift is anonymous.

1.What reaction does Linda imagine the children will have?

(No more than 5 words)                                       (2 marks)

________

2.Why did Linda join the American Women's Club of Toronto?

(No more than 10 words)                                      (2 marks)

________

3.Why did Linda ask for a second wish list?

(No more than 15 words)                                      (3 marks)

________

4.What kind of people does "secret Santas" in the passage refer to?

(No more than 12 words)                                      (3 marks)

________

How do you wake up in the morning? Imagine you set an alarm on your phone or clock that goes off like this: beep beep beep. 1. The state is known as grogginess (东倒西歪). So, is there a better way to wake up? A recent study says yes. The answer is music. Researchers say alarms that have a melody can help people feel fresher in the morning.

Sleep inertia (睡后迟钝) is another term for grogginess. 2. Someone even has trouble getting moving again after sleeping. Stuart McFarlane was a lead writer of the study. He said people need to better understand sleep inertia’s harmful effects on human performance later in the day. The grogginess we may feel in the morning has been reported to last from two to four hours.

3. But for those who do, care should be taken when perform duties that require a top performance within this period. 4. The same is true for people like pilots and firefighters. Sleep inertia has been linked to major accidents including airplane and shipping crashes.

What makes musical alarms better for waking up? The researchers think the music may be more successful in reducing sleep inertia because it has several tones, compared to the single tone of a “beeping” alarm. 5.

No matter how you wake up, experts say, the amount of sleep you get also matters a lot.

A.It means a person has a heavy feeling when waking up.

B.This includes dangerous tasks like driving or riding bikes shortly after waking up.

C.That harsh sound may make it harder to shake off the sleepy feeling.

D.Not everyone will experience the full effect.

E.The unpleasant beep is expected to be successful at waking up a person.

F.The changes over time may help increase a person’s attention when waking from sleep.

G.People who wake up to musical alarms feel more awake and alert.

Do you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.

During the hours when you labour through your work, you may say that you’re “hot”. That’s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people that peak comes during the forenoon. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues （自言自语）as “Get up , John ! You’ll be late for work again !” The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has.

You can’t change your energy cycle, but you can make your life fit it better. Habit can help. Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract your cycle to some extent by habitually staying up later than you want to . If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won’t change your cycle , but you’ll get up steam and work better at your low point .

Get off to a slow start which saves your energy. Get up with a yawn and stretch. Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon and save tasks requiring more energy for your sharper hours .

1.If you want to work better at your low point in the morning, you should 　　 .

A. change your energy cycle 　　　　　　　　　 　　　　　　　　　 B. overcome your laziness

C. get up early than usual 　　　　　　　　　 　　　　　　　　　 D. go to bed earlier

2.You are advised to rise with a yawn and stretch because it will 　　　　 .

A. help to keep your energy for the day’s work

B. help you to control your temper early in the day

C. enable you to get your energy on your routine work

D. keep your energy cycle under control all day

3.What’s the best title of the passage?

A. Change Your Habits 　　　　　　　　　 　　　　　　　　　 B. Save Your Energy

C. Daily Energy Cycle 　　　　　　　　　 　　　　　　　　　 D. Temperature-and-Energy Peak

A. news report　　　　　　　　　　　　　　　 B. research paper

Do you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle (能量周期).

During the hours when you labour through your work you may say that you’re “hot”. That’s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak.
