In the rush to get to school, you drop a piece of toast on the floor. Do you throw it away or decide it’s still OK to eat? If you’re like most people, you eat it. Maybe you follow the “5-second rule”, which claims foods are safe to eat if you pick them up within 5 seconds after dropping them.      

But you might want to think again. Scientists now say that 5 seconds is all it takes for foods to become polluted with enough bacteria（细菌）to make you sick.

Bacteria can cause many kinds of illnesses. Some kinds of bacteria can grow on food. If you eat foods on which these bacteria are growing, you can become sick.

One of these food-borne bacteria is Salmonella. It makes 1.4 million people sick every year. Salmonella is often found in raw eggs and chicken. Cooking kills these bacteria, which is why it is so important to cook eggs, chicken, and other foods thoroughly.[来源:]

But how long does it take these bacteria to pollute food? A team of scientists in South Carolina did an experiment. First, they placed an amount of Salmonella on three surfaces; wood, tile (瓦片), and carpet. They placed a piece of bread and a piece of bologna（一种大红肠）on each surface for 5, 30, or 60 seconds. After just 5 seconds, both the bread and the bologna picked up enough bacteria to make you sick.

So, forget the 5-second rule. If your toast drops on the floor, throw it away and get another piece of clean toast. And this time, be careful not to drop it!

 About three hundred words in the English language come from the names of people. Many of these words are technical words. When there is a new invention of discovery, a new word may be coined(杜撰) after the inventor or scientist.

  It is interesting to observe how many common words have found their way into the language from the names of people. Lord Sandwich, who lived from 1718-1792, used to sit at the gambling(赌博) table eating bread with meat in between. As the Lord was the only one among his friends who ate bread in that way, his friends began to call the bread “sandwich” for fun. Later on，the word became part of the English language.

  The word “boycott” means to refuse to have anything to do with somebody or something. It comes from a man called Captain Boycott. He was a land agent in 1880 and he collected rents and taxes for an English landowner in Ireland. But the Captain was a very harsh(苛刻的) man. He treated his poor tenants (佃户) very badly. His tenants decided not to speak to him at all. Eventually word got back to the landowner and the Captain was removed（免除）. The word “boycott” became popular and was used by everyone to mean the kind of treatment that was received by Captain Boycott.

You don’t need an expert to tell you that relationships are critical to happiness．
Not being the bread-winner anymore or not being able to fulfill your kid’s needs can weigh down hard on your family life．But the trick is to stop feeling guilty and focus on caring for your loved ones．
“I was at a psychology conference where an expert was talking about the effects of this economy on families and how parents can’t afford to buy their kids luxuries like toys anymore,” says Lyubomirsky．“But what they don’t realize is that kids don’t care about toys — what they care about is parents being grumpy and taking it out on them．”
【小题4】________

Commit yourself to a project – whether it is a business you want to start or a dance you want to learn．But it’s also important to remember to be flexible in these times．
Don’t get frustrated if circumstances are stopping you from meeting your goals．Adopt and change!
“If your spouse has lost their job you might have to change your goal,” says Lyubomirsky．“Or you might have to learn a whole new skill for a new job．”
【小题5】________

Lyubomirsky says, “take time out to exercise at home．”
