[单项选择]Promptness is important in American business, academic, and social settings. The importance of punctuality is taught to young children in school. Tardy slips and the use of bells signal to the child that punctuality and time itself are to be respected.
People who keep appointments are considered dependable. If people are late to job interviews, appointments, or classes, they are often viewed as unreliable and irresponsible. In the business world, "time is money" and companies may fine their executives for tardiness to business meetings. Of course it is not always possible to be punctual. Social and business etiquette also provides rules for late arrivals. Calling on the telephone if one is going to be more than a few minutes late for scheduled appointments is considered polite and is often expected. Keeping a date of a friend waiting beyond ten to twenty minutes is considered rode. On the other hand, arriving thirty minutes late to some parties is acceptable.

HIV & AIDS
AIDS has now surpassed the Black Death on its course to become the worst pandemic in human history. At the end of 2004, 20 million people had been killed by it, and twice that number is currently infected with HIV. Barring a medical breakthrough, it could claim the lives of some 60 million people by 2015. AIDS exerts a terrible toll on societies, crippling their economies, decimating their labor forces and orphaning their children.
Nine out of 10 people living with HIV are in the developing world; 60 to 70% of those are in Sub-Saharan Africa. But the disease is spreading in every region, with fierce epidemics threatening to tear through countries such as India, China, Russia and the islands of the Caribbean. The statistics are sobering — in some Southern African towns 44% of pregnant women are HIV positive, in Botswana 37% of people carry the virus.

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 between 2 am and 4 am. 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 volunteers slept less well after a cup of caffeinated coffee than after drinking the same amount of decaf. On average, subjects slept 336 minutes
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 hormon
