Late-Night Drinking
Coffee lovers beware. Having aquick" pick-me-up" cup of coffee late in the day will playhavocwith your sleep. As well as being astimulant, caffeine interrupts the flow of melatonin, theB.rain hormone that sends people into asleep.
Melatonin levels normally start to rise about two hours before bedtime. Levels then peak be-tween 2 am and 4 am, before failing again. "It's the neurohormone that controls our sleep tells ourB.ody when to sleep and when to wake, "says Maurice Ohayon of the Stanford Sleep EpidemiologyResearch Center at Stanford University in California. but researchers in Israel have found that caf-feinated coffee halves the body's levels of this sleep hormone.
Lotan Shilo and ateam at the Sapir Medical Center in Tel Aviv University found that six vol-unteers slept less well after acup of caffeinated coffee than after drinking the same amount of de-caf. On average, subjects slept 336 minutes per night after drinking caffeinated coffee, comparedwith 415 minutes after decaf. They also took half an hour to drop off--twice as long as usual--andjigged around in bed twice as much.
In the second phase of the experiment, the researchers woke the volunteers every three hoursand asked them to give aurine sample. Shilo measured concentrations of abreakdown product ofmelatonin. The results suggest that melatonin concentrations in caffeine drinkers were half those indecaf drinkers. In apaper accepted for publication in Sleep Medicine, the researchers suggest thatcaffeine blocks production of the enzyme that drives tnelatonin production.
because it can take many hours to eliminate caffeine from the body, Ohayon recommends thatcoffee lovers switch to decaf after lunch.
The author mentions" pick-me-up" to indicate that__________.
A.melatonin levels need to be raised
B.neurohormone can wake us up
C.coffee is astimulant
D.decaf is acaffeinated coffee
參考答案：C
參考解析：pick-me-up指提神飲料，也就是一種刺激物，在這篇文章里具體指咖啡。所以，答案選C。
第37題單選修改
(警告：沒有校對)
Which of the following tells us how caffeine affects sleep?
A.Caffeine blocks production of the enzyme that stops melatonin production.
B.Caffeine interrupts the flow of the hormone that prevents people from sleeping.
C.Caffeine halves the body's levels of sleep hormone.
D.Caffeine stays in the body for many hours.
參考答案：C
參考解析： 第二段第三個句子談到，“控制我們睡眠的是神經(jīng)激素”，而這一段的最后一個句子告訴我們“含咖啡因咖啡能使這種激素減半”。這正是咖啡因影響睡眠的原因。
What does paragraph 3 mainly talk about?
A.Different effects of caffeinated coffee and decaf on sleep.
B.Different findings of Lotan Shilo and ateam about caffeine.
C.The fact that the subjects slept 415 tninutes per night after drinking decaf.
D.The proof that the subjects took half an hour to fall asleep.
參考答案：A
參考解析： 第三段涉及的是一個實驗，這個實驗的目的是測試含咖啡因咖啡和脫咖啡因咖啡對睡眠的影響，該段主要談論的是這個實驗的結果。
What does the experiment lnentioned in paragraph 4 prove?
A.There are more enzymes in decaf drinkers' urine sample.
B.There are more melatonin concentrations in caffeine drinkers' urine sample.
C.Decaf drinkers produce less melatonin.
D.Caffeine drinkers produce less sleep hormone that decaf drinkers.
參考答案：D
參考解析： 第四段是第三段實驗的繼續(xù)，是該實驗的第二階段。研究人員通過對志愿者尿樣進行化驗發(fā)現(xiàn)，咖啡因攝入者體內(nèi)的褪黑激素僅為非咖啡因攝入者的一半。褪黑激素就是睡眠激素，所以答案應該選D。
The author of this passage probably agrees that__________ .
A.coffee lovers sleep less than those who do not drink coffee
B.we should not drink coffee after supper
C.people sleep more soundly at midnight than at 3 a. m.
D.if we feel sleepy at night,we should go to bed immediately
參考答案：B
參考解析： 文章結尾談到，“Ohayon建議愛喝咖啡的人午飯后應該換喝脫咖啡因咖啡”。另外，整篇文章都在探討咖啡因影響睡眠的機理，所以，作者大概會同意“晚飯后不應該喝咖啡”的說法。選項A是一個全稱判斷，這等于說“所有喜歡喝咖啡的人都比不喝咖啡的人睡覺少”。這不一定，因為如果咖啡適量，喝咖啡的時間適當，咖啡不會影響睡眠。所以，作者可能不會同意這種說法。根據(jù)文章第二段第二句，選項C是錯的。根據(jù)文章第二段第一個句子，我們體內(nèi)的褪黑激素(睡眠激素)的濃度在我們上床時間前兩小時開始上升，而這個時候我們會開始有困意。反過來說就是，人們并非一有困意就睡覺。所以，選項D不是答案。
Long bus Ride
Long bus rides are like television shows. They have A.beginning, amiddle, and an end--with commercials thrown in every three or four minutes. The commercials are unavoidable. Theyhappen whether you want them or not. Every couple of minutes A.billB.oard glides by outside thebus window. "buy Super Clean Toothpaste. " "Drink Good'n Wet Root beer. " "Fill up with Pa-cificGas. " Only if you sleep, which is equal to turning the television set off, are you spared theunending cry of "You Need It! buy It Now!"
The beginning of the ride is comfortaB.le and somewhat exciting, even if you've traveled thatway before. Usually some things have changed--new houses, new buildings, sometimes even anew road. The bus driver has A.style of driving and it's fun to try to figure it out the first hour orso. If the driver is particularly reckless or daring, the ride can be as thrilling as A.suspense story.
Will the driver pass the truck in time? Will the driver move into the right or the left-hand lane?
After awhile, of course, the excitement dies down. Sleeping for awhile helps pass the middlehours of the ride. Food always makes bus rides more interesting. but you've got to be careful ofwhat kind of food you eat. Too much salty food can make you very thirsty between stops.
The end of the ride is somewhat like the beginning. You know it will soon be over and there'sakind of expectation and excitement in that. The seat, of course, has become harder as the hourshave passed. by now you've sat with your legs crossed, with your hands crossed behind your head.
The end comes just at the right time. There are just no more ways to sit.
According to the passage, what do the passengers usually see when they are on A.long bus trip?
A.B.uses on the road.
B.films on television.
C.advertisements on the board.
D.gas stations.
參考答案：C
參考解析：第一段中介紹了乘客在坐長途車過程中所見的是廣告牌。the commercials是“商業(yè)廣告”的意思;B.illB.oard是“廣告牌”的意思，即advertisements on the board。
What is the purpose of this passage?
A.To give the writer's opinion about long bus trips.
B.To persuade you to take along B.us trip.
C.To explain how bus trips and television shows differ.
D.To describe the billB.oards along the road.
參考答案：A
參考解析：全文主要介紹作者對乘車長途旅行的感受。因此選擇A。
The writer of this passage would probably favor__________.
A.bus drivers who weren't reckless
B.driving alone
C.A.television set on the bus
D.no billB.oards along the road
參考答案：D
參考解析： 第一段作者說到“The commercials are unavoidable.They happen whether you wantthem or not.”商業(yè)廣告不可避免，無論你是否需要，它都會出現(xiàn)。也說到“Only if yousleep…are you spared the unending cry of‘Yon Need It!buy It Now!”’只有睡覺才能躲避廣告。由此可以推斷出作者不喜歡沿途的廣告牌。
The writer feels long bus rides are like TV shows because__________.
A.the commercials both on TV shows and on billboards along the road are fun
B.they both have abeginning, amiddle, and an end, with commercials in between
C.the drivers are always reckless on TV shows just as they are on buses
D.both traveling and watching TV are not exciting
參考答案：B
參考解析： 根據(jù)文章第一段第一句和第二句“乘坐長途車就如同欣賞電視秀，有開端、有情節(jié)、也有結尾，每隔三四分鐘插播商業(yè)廣告”，選項B.是正確的。
The writer thinks that the end of the ride is somewhat like the beginning because both are__________.
A.exciting
B.comfortable
C.tiring
D.boring
參考答案：A
參考解析： 根據(jù)文章第二段第一句“旅程的開始是舒適并且有些興奮的”和第三段第二句“你知道旅程將很快結束，就會產(chǎn)生一種期待和興奮”選項A正確。
