It is actually caused by【52】 of your "body clock" -a small cluster of brain cells that controls the timing of biological【53】. The body clock is designed for a regular rhythm of daylight and darkness-ness, so that it is thrown out of balance when it【54】 daylight and darkness at the "wrong" times in a new time zone. The symptoms of jetlag often persist for days【55】 the internal body clock slowly adjusts to the new time zone.
Now a new anti-jetlag system is【56】 that is based on proven tentative pioneering scientific research. Dr. Martin Moore Ede has【57】 a practical strategy to adjust the body clock much sooner to the new time zone【58】 controlled exposure to bright light. The time zone shift is easy to accomplish and eliminates most of the discomfort of jetlag. A successful time zone shift depends on knowing the exact times to either【59】 or avoid bright light. Exposure sure to light at the wrong time can actually make jetlag worse. The proper schedule【60】 light exposure depends a great deal on【61】travel plans. Data on a specific flight itinerary (旅行路线) and the individual's sleep【62】are used to produce a Trip Guide with instructions on exactly when to be exposed to bright light.

While the virus can spread through droplets propelled into the air when a cold-sufferer coughs or sneezes, surprisingly, this is not the most common route of transmission. Numerous studies have now shown that the overwhelming majority of colds are "caught" by hand contact. A cold-sufferer rubs her nose, thereby transferring the virus to her hand. Then a friend comes to visit.
"Don't kiss me," she cautions, so the friend steps back and presses her hand. The friend then wipes her own nose or eye--and several days later is stricken with a cold. Or parents pick up their child's discarded(丢弃了的)tissues and carefully throw them away, but fail to wash their hands afterward.
Cold viruses also can be transferred to objects--telephones, towels, plates--and remain infections for up to three hours. Frequent hand-washing--on the part of the cold-sufferer as well as other members of the household--will minimize the spread of viruses in this way.
Colds are caused by exposure to severe weather.
A．Right
B．Wrong
C．Not mentioned
第10题
听力原文：W: Hello, Kevin. I haven't seen you for many days. What's the problem with you？
M: Actually I'm a little embarrassed about coming here. I feel fine right now. (23)But you know, every year around the holidays I would come down with something.
W: (24)So you're interested in prevention. What symptoms do you usually get？
M: You know, cough, fever, runny nose, my head and bones ache etc. I usually feel weak and it ends up ruining my holidays.
W: Sounds like a typical flu to me. (25)Influenza often strikes when people are overtired, stressed and not eating nutritious food. And also you increase your exposure to a virus when you're in big crowds where lots of people are coughing and sneezing.
M: (25)I certainly spend a lot of time in department stores around the holidays buying gifts for my family.
W: (25)Yes. And so you increase your exposure to viruses in the air just when your body's resistance is already low.
M: So what can I do to prevent from the flu？
W: Actually it's fairly simple. Get a lot of rest and eat well. That way your body will become stronger. And you'll be more able to fight off illness.
M: All these things make sense. But one more question. Am I bound to get sick anyway if there's an outbreak in the dorm？
W: I'd also suggest you get immunized. It prevents the three main types of influenza.
M: I'll do it right away. It will be nice to feel well during the holidays for once. Thank you so much, doctor.
W: That's all right.
