       Why do you think people who live in some hot countries eat very spicy (辛辣的) food? Is it because the
spices make the food taste better? Is it just because their parents and grandparents and great-grandparents liked
hot food, or is there some connection between spices and healthy food?
       Researchers from Cornell University think that it is because spice plants have some important chemicals
(化學(xué)物質(zhì)). These chemicals can kill bacteria (細(xì)菌) which spoil food. "Most common spices can kill 75 to 100
percent of the bacteria in food," explains one of the scientists. The bacteria grow more easily and spoil food
more quickly at higher temperatures. For this reason, it is more difficult to keep food from spoiling in hot
climates.
       Do you like your food spicy? Your answer probably tells something about the country you come from. If
you like spicy food, it is possible that hundreds of years ago, when there were no fridges, people in your
country started using spices to keep the food from spoiling. The traditional spicy dishes helped those people to
live longer, healthier lives. Today, in a time of fridges, the spices just make the food taste good.

       A new TV series in England, Away from it all, has surprised everyone by becoming a huge success with
young people across the country. Its success is surprising because the series is about the relaxing lifestyles of
people who live in the country. There is none of the action that we usually see on TV today. There are also no
stressful moments, busy offices or crowded cities. Away from it all is set in the peaceful English countryside
and tells simple stories about people's kindness. 
       The director of the TV series says that its success is a sign of teenagers suffering from stress. They say
that watching Away from it all helps teenagers forget about the pressures (壓力) of exams and homework, and
the troubles that fill the world today. They also say that it's a good sign of today's young people switching to
(轉(zhuǎn)到) happier TV series as it shows they would like a happier and healthier world. 
       Although the series' success might have a good side, many teachers and parents are worried, however.They
say that some of their students and children are becoming couch potatoes (終日泡在電視機(jī)前的人) and are
using Away from it all as an excuse for not completing homework. Some children have even refused to learn for
exams because they say that they can only achieve personal happiness by avoiding (避免) stressful situations
completely. 
       And what do the experts (專家) say? Paula Ray, a doctor of education, says that TV can influence
children's lifestyles. But she says that if a child reacts strongly, it's likely that there are other reasons for his
change in behaviour. She says that there is nothing wrong with watching Away from it all but suggests that
parents should make sure their children know TV is not the same as real life.
