A blow-fly was looking for an ideal place like rotting meat to lay her eggs so that when her little babies were born, they could feed on the meat.
As she turned a corner in the grassland, she smelt something that smells like rotten meat in the air! With a great joy she landed on it and laid her eggs. She was happy that her children would have enough food to eat.
But the fly did not know she had made a great mistake. What she had sat upon was not meat but a flower, which smells badly. It is called a carrion flower. So, when the blow-fly’s eggs hatched and the little maggots(蛆)came out, they had nothing to eat. They died of starvation.
The carrion flower is one of the many flowers which send out dirty smells to attract flies. The Rafflesia stinks like rotting meat, while the tropical Lords and Ladies flower gives out a smell like rotting fish.
They do it for a special reason. These plants cannot move from their place. But it is important for the male cell of one plant to get in touch with the female cell of another plant. Once that is done, the seed of the plant will bloom and give birth to another plant.
The plant uses its stink to attract flies. As soon as the blow-fly sits on the follower, it is captured by the flower with strong hair. When the hair falls, the fly is free to fly- but it takes some pollen(花粉) with it. And goes and sits on another plant. The male cell of one plant meets the female cell of the other. The seed gets new life.

Millions of people are using cell phones today.In many places it is actually considered unusual not to use one.In many countries,cell phones are very popular with young people.They find that the phones are more than a means of communication—having a mobile phone shows that they are cool and connected.
The explosions around the world in mobile phone use make some health professional worried.Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones.In England,there has been a serious debate about this issue.Mobile phone companies are worried about the negative publicity of such ideas.They say that there is no proof that mobile phones are bad for your health.

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.
The 57yearold,fatherofthree,revealed on The Today Show that his children Jennifer and Rory were not allowed phones until their 13th birthday and his youngest daughter Phoebe is still waiting for one.
“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.
“What you really feel is what you’ve achieved.If a piece of software gets out there and lots of people love it—it lets them get their work done in better ways—that’s exciting,” he explained.Bill Gates will not let his children own a cell phone________.

“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?

A.The infant death rate always stays high. |
B.People are crazy to have only one child. |

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. Robert Stickgold’s test shows that________.
A.games are useful for memory |
B.dreams can help improve skills |
C.players stop learning in dreams |
D.tasks can only be settled through dreams |
We can learn from Paragraph 4 that________.

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.
