16、ys. Air travelers can get very tired and develop unpleasant feelings when they fly great distances across time zones. The natural order of things can become unbalanced on long, overseas trips from east to west or from west to east. So today we are going to talk about jet lag and how to overcome it.
17、The natural system tells our bodies when to sleep and helps to control many other processes. This internal body clock is affected by environmental signals, like sunlight and temperature. Sometimes we use the word desynchronized when talking about jet lag. This means to cause a process that takes pla
18、ce at times or in cycles independent of another process. In unscientific terms, you might say out of sync or out of whack. Cells change their activity when a light is shown directly on them. They actually become desynchronized amongst the groups and within the groups. So when you feel out of whack w

21、eep on your trip. 2. Start making small changes while in flight Change your watch when you get on the airplane. This is playing a trick on the mind. But it can help you to start thinking of the time at the other end of the flight. Try to sleep on the plane if it is nighttime in the place where you a
22、re going. Try to stay awake if it is daytime. 3. Arrive early If you are traveling for work or for a personal reason, try to arrive a few days earlier, if possible. This will give your mind and body more time to correct to the new hours. 4. Drink water Drink lots of water before, during, and after y
23、our flight. Avoid drinking alcohol or caffeine a few hours before you plan to sleep. Alcohol and caffeine can interfere with sleep. 5. Move around During your flight, get up and walk around or stretch so often. But after you land, avoid heavy exercise near bedtime. Exercise near bedtime can delay sl
24、eep, whether on an overseas trip or at home. If you travel, what are some tips you use to make it more enjoyable?. 解析 信息题。录音一开始提出长时间飞行给人体带来的影响，“A long flight can affect ones biological clock, sometimes for days.”，即生物钟的紊乱。 填空项1:_（正确答案：environmental signals。）解析： environmental signals。解析 细节题。录音指出“This
25、internal body clock is affected by environmental signals.”。生物钟受外界环境影响。 填空项1:_（正确答案：temperature。）解析： temperature。解析 信息题。sunlight是提示信息，和sunlight同时出现的为正确答案。 填空项1:_（正确答案：activity。）解析： activity。解析 信息题。当说到产生时差反应的过程时，“Cells change their activity when a light is shown directly on them.”，即受到光线刺激，细胞会改变活动。此时录音
26、中用的是单数形式，答案为单数形式。 填空项1:_（正确答案：the nervous system。）解析： the nervous system。解析 信息题。录音中提到“.your nervous system actually reflects that same thing in becoming desynchronized within itself.”。神经系统内部会失调。 填空项1:_（正确答案：small changes。）解析： small changes。解析 信息题。这是录音提到的第二个建议。从题目可以看出这是一个大的信息点。 填空项1:_（正确答案：stay awake
27、。）解析： stay awake。解析 细节题。在第二个建议中，录音提到“Try to sleep on the plane if it is nighttime in the place where you are going. Try to stay awake if it is daytime.”。要根据目的地来调整睡眠时间。 填空项1:_（正确答案：arrive early。）解析： arrive early。解析 信息题。这是录音提到的第三个建议，是一个大的信息点。 填空项1:_（正确答案：alcohol or caffeine。）解析： alcohol or caffeine。解析
28、 细节题。在录音提到的第四个建议drink water中，“Avoid drinking alcohol or caffeine a few hours before you plan to sleep. Alcohol and caffeine can interfere with sleep.”即酒和咖啡因会影响睡眠，要避免。 填空项1:_（正确答案：heavy exercise。）解析： heavy exercise。解析 细节题。在录音提到的第五个建议move around中提到“But after you land, avoid heavy exercise near bedtime
29、. Exercise near bedtime can delay sleep, whether on an overseas trip or at home.”可知，临睡前不要做剧烈运动，会影响睡眠。near bedtime是提示信息。 四、SECTION B CONVERSATI(总题数：2，分数：30.00)（分数：15.00）A.How to change a job.B.How to get a promotion.C.How to get a pay raise.D.How to handle difficulties in life.解析：听力原文 M: Hey, Alice!
