【题目】Everybody sleeps, but what people stay up late to catch or wake up early in order not to miss varies by culture?

From data collected, it seems the things that cause us to lose the most sleep, on average, are sporting events, time changes, and holidays.

Around the world, people changed sleep patterns thanks to the start or end of daylight savings time. Russians, for example, began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to "winter time" starting on October 26.

Russia's other late nights and early mornings generally correspond to public holidays. On New Year's Eve, Russians have the world's latest bedtime, hitting the hay at around 3:30 a. m.

Russians also get up an hour later on International Women's Day, the day for treating and celebrating female relatives.

Similarly, Americans' late nights, late mornings, and longest sleeps fall on three-day weekends.

Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey (冰球) final.

The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it, and then they woke up earlier than usual the next morning thanks to summer nights, the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing, though, compared to Germans, Italians, and the French, who stayed up around an hour and a half later on various days throughout the summer to watch the Cup.

It should be made clear that not everyone has a device to record their sleep patterns; in some of these nations, it’s likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that’s the case, though, the above findings are still striking. If the most health-conscious among us have such deep swings in our shut-eye levels throughout the year, how much sleep are the rest of us losing?

1What do we learn about the Russians regarding sleep?

A. They don’t fall asleep until very late. B. They don’t sleep much on weekends.

C. They sleep longer than people elsewhere. D. They get less sleep on public holidays.

2The underlined word “deprivation” in the last paragraph but one means ________.

A. depression B. loss C. observation D. trouble

3What is the most probable reason for some rich people to use a device to record their sleep patterns?

A. They have trouble falling asleep. B. They are involved in a sleep research.

C. They want to get sufficient sleep. D. They want to go to bed on regular hours.

4What does the author imply in the last paragraph?

A. Sleeplessness does harm to people’s health.

B. It is important to study our sleep patterns.

C. Few people really know the importance of sleep.

D. Average people probably sleep.

Quicker and faster 3-D printers have allowed not just amazingobjects to be created, but have started to affect how doctors treat patients.
Weve put together a list of some of the most amazingmedical breakthroughs made possible with 3-D printing.
Life-Saving Airway
In 2013, doctors created a new airway for kaiba Gionfriddo, aboy born with an airway that kept collapsing (萎陷). To save hislife doctors printed tiny tubes to join together in different shapes and sizesuntil one finally worked for Kaiba. It was placed in Kaibasbronchus (支气管) so that itno longer collapsed. Even more remarkably, once the plant was placed it couldstay there. Its designed to eventually be absorbed into the body.
New “Bionic” Hands
One of the most remarkable ways 3-D printing is now being usedis as a way to create prosthetics (假肢). A boy bornwithout an arm named Alex was able to get a new“bionic”hand thanks to it. Lastyear a college student spent 8 weeks coming up with a special prosthetic designthat only cost a few hundred dollars in materials. He said he wanted to createa prosthetic far cheaper than other choices that can run tens of thousands ofdollars.
A practice Heart
In Seattle, doctors have been able to use 3-D printingtechnology to“practice”risky operations so that they will face fewer surprisesin the operating room. Kami Sutton was born with her heart“in the wrong place”.For a recent operation her doctor was able to take many scans of Suttons heart and print out a model. “Kamis heart is trulyone-of-a-kind,”Dr. Stephan Seslar, a heart disease specialist said. “Operatingon her without understanding the structure of her heart better could be very dangerous.”
A New Skull
A U.K. man was able to have part of his skull rebuilt thanks toa 3-D printer. Stephen Power broke his cheek bones in a crash. To help Powerhis doctors instead created 3-D bones all carefully printed in the shape of hisface. “This is really the first time weve taken it to this stage,where everything has been planned and modeled in advance — and workedsweetly,”said Adrian Sugar, a doctor.
(1)What is special about the 3-D printed airway?
A.It uses high-tech materials.
B.It varies in shapes and sizes.
C.It can be absorbed by the body.
D.It can prevent any disease in the airway.
(2)What is the advantage of the new“bionic”hand?
A.Its price.
B.Its effects.
C.Its materials.
D.Its shape design.
(3)How can 3-D printing technology help doctors in the operating room?
A.It helps them get better scans.
B.It guarantees the success of operations.
C.It enables them to practice and learn more.
D.It helps them to deal with patents, anxiety.
(4)What does Adrian Sugar think of the new skull printed by 3-D technology?
A.He has doubts about it.
B.He thinks highly of it.
C.It needs to be better planned.
D.It functions well but needs improving.
