Food sometimes gets poisoned with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly, The symptoms ( 症状) of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.
Certain microorganisms (微生物) cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release (释放) poisons that make people sick.
Some chemicals can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with ditty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be co
oked thoroughly to kill any dangerous microorganisms. People should also wash foo
d covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.

Microsoft founder Bill Gates has opened up about being a parent，stating that 13 is an appropriate age for a child’s first cell phone.

“We’ve chosen in our family that it’s 13 where you get a phone，” the selfmade billionaire explained.
He said as a result his children often return home from school complaining，“All the other kids have one.I’m the only one without one.It’s so embarrassing.”
Asked if he keeps passwords to his son and daughters’ email and Facebook accounts，Mr Gates said that he doesn’t for Jennifer,16，who he describes as “independent”．He admitted that monitoring online activity is “a very tricky issue for parents now”．
Despite their vast wealth Mr and Mrs Gates，who live in Lake Medina，have said they want to give their children as normal an upbringing as possible.
It was previously reported that their youngsters have to complete household chores and are given a modest amount of pocket money.
And in 2010 Mr Gates said that he intends to give most of his $61 billion fortune away rather than hand it down.“That wouldn’t be good either for my kids or society，” he said.
Also during the Today interview with host Matt Lauer，Mr Gates，who stepped down from Microsoft in 2008 to concentrate on philanthropy，said that helping others gives him the same excitement as creating software.

“Oh，you must have been a spoiled (宠坏的) kid.You must be really bossy.I wonder what you’re going to be like to deal with？” That’s often the response Angela Hult gets when people find out she’s an only child，she told ABC News.Despite such negative (消极的) remarks，Hult has decided to have only one child herself.And she’s not alone.
According to the US’ Office for National Statistics，women approaching the end of their childbearing years had an average of 1.9 children in 2004，compared with 3.1 for their counterparts in 1976.The percentage of onechild families in Britain had risen from 18 percent in 1972 to 26 percent in 2007.
But even though only children are becoming increasingly common，the traditional view that they’re selfish，spoiled and lack social skills holds strong.Even parents of only children，like Hult，are made to feel guilty about having only one child.Worried that they’re being selfish and endangering their child’s future，they flock to online discussion forums seeking advice.Soon，however，they ask themselves：is this social prejudice really reasonable?
“There have been hundreds and hundreds of research studies that show that only children are no different from their peers (同龄人)，” Susan Newman，a social psychologist at Rutgers University in the US，told ABC News.
This raises another question：why are only children still viewed with such suspicion?
“There is a belief that’s been around probably since humans first existed that to have just one child is somehow dangerous，both for you and for the continuation of your race，” Toni Falbo，a professor of educational psychology，told the Guardian.“In the past a lot of children died.You’d have had to be crazy to only have one.”
Times，of course，have changed and infant mortality (婴儿死亡率) has largely reduced.So what do only children themselves say?
Kayley Kravitz，a blogger for The Huffington Post，grew up as an only child and highly recommends the experience.“Being an only child taught me the most valuable skill of all：the ability to be alone，” she said. Which of the following could be the best title for the text?

When you tidy your messy bedroom，it gets a lot easier to find things.Dreams may work the same way for a messy brain，helping you learn by organizing memories and ideas.
To test how much dreams can help learning，Robert Stickgold had some students play a shapefitting game called Tetris (俄罗斯方块) for a few hours and then go to sleep.Soon they were dreaming of falling Tetris shapes.Interestingly，the worst Tetris players had the most Tetris dreams and improved their game the most.Similar tests have shown the same results for all kinds of skills.
As we dream，many important tasks are getting done.The brain decides what to keep and what to forget.It is connecting new experiences to older learning.In fact，the brain is learning all night long.
Another important task of dreams may be to help us deal with emotions (情绪)．At night，emotions are in the driver’s seat.People who have had an upsetting experience often dream about it afterward.Often the dream event changes somehow—another way the brain tries to make the memory less upset.So if your best friend moves away，you might dream that you’re the one who’s moving.In fact，dreams have a proven power to improve mood，and people who dream about what’s bothering them usually feel better sooner than those who don’t.
Everybody dreams for a couple of hours every night—in the course of your life，you’ll spend about 25 years asleep and 6 years dreaming.There’s probably no single answer to the question why we dream，but there doesn’t have to be.One dream might help you remember your math facts，while another might lead to a new invention，or give you a fun，crazy story to tell your friends.It’s all in a night’s work for our busy，mysterious brains.

Depression (抑郁症) is a serious problem today.Depression causes workers to be unproductive，causing companies and countries to lose billions of dollars.One expert says that depression is like cancer because it is “widespread，costly and deadly”．Depression hits one person in five around the world.
Although people have believed depression to be a problem among the rich and educated，studies show that depression is a problem among everyone.Over any sixmonth period，between five to seven percent of the world’s population will be suffering from a serious depression.Suicide rates among people suffering from the disease in its extreme，or clinical form were 80 percent higher than in the population at large，and sufferers were four times more likely to have heart attacks.People who suffer from depression often have problems sleeping，getting up on time，and doing work productively.
Depression，which researchers agree has its origin in the genes，brings loss of confidence and ability to concentrate—making it impossible for employees and managers to work efficiently.
Depression is made more serious in China by Chinese’s inability to face it.Many people believe that depressed people are either weak or lazy.Besides，there is no good treatment，with few specialists available.“Most patients in China just don’t get help，”a Chinese doctor says.“In my hospital，I have to see 30 or 40 patients in a morning，just have time to say ‘Hello，how do you feel？’”
In Western countries，people are not afraid to admit that they have depression，but most do not tell it to their boss，because they fear that they will be stricken_off_the_rolls.“In my experience，aging bosses are the most willing to admit they have it.Because they feel the most secure about themselves，” an American doctor says.

Rae and Bruce Hostetler not only work very hard，they also relax just as well.Numerous vacations help the couple to maintain their health and emotional wellbeingand it’s no surprise to health care professionals.
“Rest，relaxation，and stress reduction are very important for people’s wellbeing and health.This can be accomplished through daily activities，such as exercise and meditation，but vacation is an important part of this as well，” said primary care physician Natasha Withers from One Medical Group in New York.Withers lists a decreased risk of heart disease and improved reaction time as some of the benefits from taking some time off.“We also know that the mind is very powerful and can help with healing，so a rested，relaxed mind is able to help the body heal better，” said Withers.
Psychologists confirm the value of vacations for the mind.“The impact that taking a vacation has on one’s mental health is great，” said Francine Lederer，a clinical psychologist in Los Angeles who specializes in stress and relationship management.“Most people have better life perspective and are more motivated to achieve their goals after a vacation，even if it is a 24hour timeout.” The trips could be good for their health，good for their family and good for their businesses.
The online travel agency Expedia conducted a survey about vacation time in 2010，and according to their data the average American earned 18 vacation days—but only used 14 of them.France topped the list，with the average worker earning 37 vacation days and using all but two of them.Americans’ responses may not be surprising in a culture where long hours on the job often are valued，but that’s not always good for the individual，the family or the employer.
Psychologists have also found that people who don’t take enough time to relax may find it harder to relax in the future.“Without time and opportunity to do this，the nerve connections that produce feelings of calm and peacefulness become weaker，making it actually more difficult to shift into lessstressed states，” Mulhern said.How did the author introduce the topic of the text?
