Studies show that during your teenage years, the body's biological clock is reset, telling you to sleep later at night and wake up later in the morning.

Russian tradition orders that men should kiss each other three times on the cheeks at official functions. Now, a new ruling in Moscow is calling for politicians in the capital to stick to the old handshake. According to Britain's The Telegraph newspaper, politicians in Moscow have been told to stop kissing each other when they meet because the “kissing ceremony” takes so long.
Leonid Brezhnev, the general secretary of the Communist Party from 1964 to 1982, was famous for treating male colleagues to a full lip-lock. One photograph of him kissing Erich Honecker, the leader of the Democratic Republic of Germany, was used for a protest painting on the Berlin Wall with the caption: "Oh, God, help me survive this deadly love".
Kissing three times on the cheeks at official occasions is a Russian tradition. The practice has been revived among high-ranking officials in past years. In the distant past, a kiss from the tsar (emperor) was the highest sign of recognition. The Moscow ruling, however, has prompted authorities in other cities to consider banning the practice.
Alexei Kleshko, a parliament member in Siberia, said: “Single-sex kisses should be avoided, including at official meetings. It's enough to shake hands. Of course, if one is talking about a long friendship or fatherly relations, it might be OK to embrace. But that's the maximum that should be allowed.” w.w.w.k.s.5.u.c.o.m
Another MP Vladimir Gorlov, said he only allowed himself to kiss the hand of a woman at work: "There are informal relations and there are meetings governed by protocol," he said. “When a man is kissing another man at an official event, I have a negative attitude towards it. There are rules of decency. "

A. it is popular at home and abroad B. it is their tradition

6. By mentioning Brezhnev, the author ________.
A. wants to show his respect to Brezhner
B. admires Brezhnev for his skills at kissing
C. just shows the media made fun of pictures of politicians kissing
D. praises Brezhnev’s good relation with Honecker
7. If the tsar kissed a Russian woman, she would feel ________.
A. nervous B. proud C. shameful D. curious
8. We can infer from the last two paragraphs that ________.
A. Kleshko is strongly against any kind of kiss
B. Kleshko is a man out of date
C. Gorlove shares the same view with Kleshko is single-sex kisses
D. Gorlove won’t kiss any man in any form w.w.w.k.s.5.u.c.o.m

Have you ever dreamed of visiting a planet in the Milk Way? While the trip sounds exciting, it would take years and years to reach your destination. So in the future, bedtime for astronauts may be more than a few hours of regular shut-eye. They would have to sleep for years.
European researchers are now conducting hibernation experiments. The study may help them understand whether humans could ever sleep through the years it would take for a space flight to distant planets. "If there was an effective technology, it could make deep-space travel a reality," said Mark Ayre of the European Space Agency last month.
What seems like science fiction is not completely unlikely. Researchers have been able to use chemicals to put living cells into a sleep-like state where they don't age. They have now moved on to small, non-hibernating mammals like rats. The results will be out by the end of 2004.
A major challenge is the fact that cells can be very simple systems, whereas body organs are far more complex.
"It's like moving from a simple Apple computer to a supercomputer," said Marco Biggiogera, a hibernation researcher at Italy's University of Pavia.
Just like bears and frogs, the hibernation of human beings would cause a person's metabolism (新陈代谢) to lower so they would need less energy.
Medical research, however, is just half of a space flight hibernation system.
There is the challenge of designing a suitable protective shelter. Such a shelter would provide the proper environment for hibernation, such as the proper temperature. It would also have to monitor (监控) life functions and serve the physiological needs of the hibernator.
According to Ayre, the six-person Human Outer Planets Exploration Mission to Jupiter's moon (木星的卫星) Callisto, could be an opportunity to use human hibernation. The mission aims to send six humans on a five-year flight to Callisto, where they will spend 30 days, in 2045.
9. European researchers are conducting hibernation experiments to ________.
A. ensure astronauts to get a complete sleep B. find the secret of some creatures
C. make preparations for the journey to Jupiter’s moon Callisto
D. know if man can sleep for years
10. The sentence “What seems like science fiction is not completely unlikely” means ________. w.w.w.k.s.5.u.c.o.m
A. Science fiction is people’s imagination.
B. Science fiction is imaginative, but it can be realized.
C. Things seem impossible may come true.
D. Things described in science fiction are sure to become true.
11. The passage is implied but doesn’t states that ________.
A. putting living cells into a sleep-like state is full of failure
B. Biggiogera is confident with the experiment
C. human’s hibernation needs no energy
D. medical research is the key to space flight hibernation system
12. By designing a suitable protective shelter, astronauts can ________.
A. have a good hibernation B. lessen the pressure of traveling in space
C. feed themselves in spaceship D. moinitor their body changes
13. What’s the best title for the passage?
A. Six humans to fly to Callisto B. Human hibernation improves health
C. Space travel attracts people D. Deep sleep for deep space travel
