[不定项选择题]共用题干 Late-Night Drinking
Coffee lovers beware .Having a quick"pick-me-up"cup of coffee late in the day will play havoc with your sleep.As well as being a stimulant,caffeine interrupts the flow of melatonin,the brain hormone that sends people into a sleep.
Melatonin levels normally start to rise about two hours before bedtime.Levels then peak be-tween 2 a.m.and 4 a. m.,before falling again."It's the neurohormone that controls our sleep and tells our body when to sleep and when to wake,"says Maurice Ohayon of the Stanford Sleep Epidemiology Research Center at Stanford University in California. But researchers in Israel have found that caffeinated coffee halves the body's levels of this sleep hormone.
Lotan Shilo and a team at the Sapir Medical Center in Tel Aviv University found that six vol- unteers slept less well after a cup of caffeinated coffee than after drinking the same amount of de-caf（脱因咖啡）.On average , subjects slept 336 minutes per night after drinking caffeinated cof-fee,compared with 415 minutes after decaf. They also took half an hour to drop off-twice as long as usual-and jigged around in bed twice as much.
In the second phase of the experiment,the researchers woke the volunteers every three hours and asked them to give a urine sample,Shilo measured concentrations of a breakdown product of melatonin .The results suggest that melatonin concentrations in caffeine drinkers were half those in decaf drinkers.In a paper accepted for publication in Sleep Medicine,the researchers suggest that caffeine blocks production of the enzyme that drives melatonin production.
Because it can take many hours to eliminate caffeine from the body,Ohayon recommends that coffee lovers switch to decaf after lunch. What does the experiment mentioned 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.

[不定项选择题]共用题干 The Making of a Success Story
1 .IKEA is the world's largest furniture retailer,and the man behind it is Ingvar Kamprad,one of the world's most successful entrepreneurs.Born in Sweden in 1926,Kamprad was a natural business man.As a child,he enjoyed selling things and made small profits from selling matches,seeds and pencils in his community.When Kamprad was 17,his father gave him some money as a reward for his good grades.Naturally he used it to start up a business一IKE A.
2 .IKEA's name comes form Kamprads'initials(I.K.)and the place where he grew up (E and A).Today IKEA is known for its modern,minimalist furniture,but it was not a furniture company in the beginning.Rather,IKEA sold all kinds of miscellaneous goods. Kamprad's wares included anything that he could sell for profits at low prices,including watches,pens and stockings.
3 .IKEA first began to sell furniture through a mail-order catalogue in 1947.the furniture was all designed and made by manufactures near Kamprad's home.Initial sales were very encouraging,so Kamprad expanded the product line.Furniture was such a successful aspect of the business that IKEA became solely a furniture company in 1951. 4 .In 1953 IKEA opened its first showroom in Almhult,Sweden.IKEA is known today for its spacious stress with furniture in attractive settings,but in the early 1950s, people ordered from catalogues.Thus response to the first showroom was overwhelming:people loved being able to see and try the furniture before buying it.This led to increased sales and the company continued to thrive.By 1955,IKEA was designing all its own furniture.
5 .In 1956 Kamprad saw a man disassembling a table to make it easier to transport.Kamprad was inspired.The man had given him a great idea:flat packaging.Flat packaging would mean lower shipping costs for IKEA and lower prices for customers.IKEA tried it and sales soared.The problem was that people had to assemble furniture themselves,but over time, even this grew into an advantage for IKE A.Nowadays,IKEA is often seen as having conno-tations of self-sufficiency.This image has done wonders for the company,leading to better sales and continued expansion.
6 .Today there are over 200 stores in 32 countries.Amazingly,Ingvar Kamprad has man-aged to keep IKEA a privately-held company.In 2004 he was named the world's richest man.He currently lives in Switzerland and is retired from the day-today operations of IKE A.IKEA itself,though,just keeps on growing. As flat packaging saves money for both IKEA and the customers,______.
A.IKEA began as a small store'selling all kinds of things of low prices
B.it is highly welcomed by both
