because they have too much homework, which keeps them up at night. some teens cannot sleep at night even when they want to. studies show that during your teenage years, the bodys biological clock is reset, telling you to sleep later at night and wake up later in the morning. but changes in the body clock arent the only reason teens lose sleep. lots of people have insomnia (失眠). the most common cause of insomnia is stress. but all sorts of things can lead to insomnia. these include physical discomfort, emotional troubles and even sleeping environment. its common for everyone to have insomnia

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 britains 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. its enough to shake hands. of course, if one is talking about a long friendship or fatherly relations, it might be ok to embrace. but thats the maximum that should be allowed.”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. 5. moscow is calling for politicians to stick to handshake because _. a. it is popular at home and abroad b. it is their traditionc. it saves time d. russian women have a strong love of it6. by mentioning brezhnev, the author _. a. wants to show his respect to brezhnerb. admires brezhnev for his skills at kissingc. just shows the media made fun of pictures of politicians kissingd. praises brezhnevs good relation with honecker7. if the tsar kissed a russian woman, she would feel _. a. nervous b. proudc. shameful d. curious8. we can infer from the last two paragraphs that _. a. kleshko is strongly against any kind of kissb. kleshko is a man out of datec. gorlove shares the same view with kleshko is single-sex kissesd. gorlove wont kiss any man in any form（三）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 dont 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. its like moving from a simple apple computer to a supercomputer, said marco biggiogera, a hibernation researcher at italys university of pavia. just like bears and frogs, the hibernation of human beings would cause a persons metabolism (新陳代謝) 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 (監(jiān)控) life functions and serve the physiological needs of the hibernator. according to ayre, the six-person human outer planets exploration mission to jupiters moon (木星的衛(wèi)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 creaturesc. make preparations for the journey to jupiters moon

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 doesnt states that _. a. putting living cells into a sleep-like state is full of failureb. biggiogera is confident with the experimentc. humans hibernation needs no energyd. medical research is the key to space flight hibernation system12. by designing a suitable protective shelter, astronauts can _. a. have a good hibernation b. lessen the pressure of traveling in spacec. feed themselves in spaceship d. moinitor
