Tu Youyou has become the first Chinese woman to win a Nobel Prize, for her work in helping to create an anti-malaria(瘧疾) medicine. The 84-year-old’s route to the honour has been anything but traditional. In China, she is being called the "three nos" winner: no medical degree, no doctorate, and she’s never worked overseas.

In 1967, malaria, a then deadly disease, spread by mosquitoes was decimating Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit “Mission 523 “was formed to find a cure for the illness. Two years later, Tu Youyou was instructed to become the new head of “Mission 523”.

“Mission523” read ancient books carefully for a long time to find historical methods of fighting malaria. When she started her search for an anti-malarial drug, more than 240,000 compounds(化合物) around the world had already been tested, without any success. Finally, the team found a brief reference to one substance, sweet wormwood（青蒿）, which had been used to treat malaria in China around 400 AD. The team took out one active compound in wormwood, and then tested it. But nothing was effective until Tu Youyou returned to the original ancient text. After another careful reading, she changed the drug recipe one final time, heating the compound without allowing it to reach boiling point.

After the drug showed promising results in mice and monkeys, Tu Youyou volunteered to be the first human recipient of the new drug. “

In any case, Tu Youyou is consistently praised for her drive and passion. One former colleague. Lianda Li, says Ms Tu is “unsociable and quite straightforward”, adding that “if she disagrees with something, she will say it.”

Another colleague, Fuming Liao, who has worked with Tu Youyou for more than 40 years, describes her as a “tough and stubborn woman”. Stubborn enough to spend decades piecing together ancient texts, she applies them to modern scientific practices. The result has saved millions of lives.

As always the butterflies left everyone with their twist and turns, and their wonderful colours. When it was time for the ants to perform, it seemed like the competition had already been decided.

For the time in living memory, the ants shared just one balloon between them, and one by one they climbed up the balloon string, a thin black thread of ants. When all the string was covered, the last ant climbed his teammates to reach the balloon. he got there, he climbed onto the top of the balloon.

This strange attracted everyone's curiosity, and they were just about to witness the most important : the ant opened his jaws as wide as he could. . . and then he made a violent movement at the balloon with all his strength!

The result was powerful! The balloon began blowing out its air, flying about, here and there, doing a thousand turns and spins, while the ants made all kinds of beautiful shapes out of the string.

Of course, that acrobatic(雜技般的) flight with quite a hard landing, but it didn't . The creativity and teamwork of the ant performance was so that the crowd didn't even have to vote for there to be a winner.

From then on, in that garden, everyone understood how much could be achieved by working . In the years to come, the balloon competitions were full of displays carried out by teams, and they put on some wonderful routines; something those individual insects could never have achieved on their own.

Think about what you usually have for a meal: Is it a hamburger? What about vegetables? Would it surprise you to learn that what you eat can affect the whole planet?

It can--in a big way. Scientists attending the American Association for the Advancement of Science meeting in Chicago presented new studies showing how food and its production affect the globe and its warming climate. It is generally believed that global warming is caused by the large amounts of greenhouse gases released into the atmosphere. One of these greenhouse gases is carbon dioxide.

What does this have to do with food? A big part of the carbon dioxide comes from the process of making and eating food, the scientists reported in Chicago. The production of meat contributes to a lot of that carbon dioxide.

The process of making a hamburger, for example, requires a lot of energy. A cow has to be fed and raised on farmland, and cow manure(肥料)is a major source of methane(甲烷)--an especially powerful greenhouse gas. By the time a hamburger is finally served on a dinner plate, it has done great harm to the environment.

The message from the research is clear: We can greatly reduce the production of greenhouse gases by eating less meat.

All kinds of meat, the scientists reported, are harder on the planet than vegetables. To grow and eat a pound of potatoes, for example, sends less than one-quarter pound of carbon dioxide or other greenhouse gases into the air. So shifting our diet to less meat and more vegetables ,as it turns out, may do the world some good.

1.Generally speaking , people believe that global warming is caused by ________.

A. cutting down too many trees.

B. releasing too many greenhouse gases.

C. growing too many vegetables.

D. raising too many cows.

2.Which of the following is NOT true?

A. To make and eat meat requires a great deal of energy.

B. To feed and raise cows on farmland contributes to greenhouse gases.

C. To make and eat hamburgers sends greenhouse gases into the air.

D. To grow and eat vegetables does no harm to the environment.

3.According to the passage , the writer seemingly intends to ________.

A. appeal to us to protect the environment by eating less meat food.

B. persuade us to develop a good eating habit to keep healthy

C. advise us to make less hamburgers in order to save energy.

D. encourage us to grow more vegetables to reduce greenhouse gases.

Finding summer jobs for teenagers has not always been easy, but now you no longer have to worry about what your kid can do to earn their own money．Recently I found some different sites online that offer information about what kids can do．Below is some of that information, along with questions to think about to help you come up with your own ideas．

Ideas for summer work

●Parks and Recreation Programs．

●Babysitting （當臨時保姆） during the day of school．

●Working part-time at a day care for the summer．

●Car washing．

●Working at local vegetable stands．

The easiest way for you to find ways for your child to make money is to think about others’ inconveniences （不方便）．Think of things you need done, or would like to have done, and what you would consider paying for these things to get done．Once you have some ideas, you can sit down with your child and talk to them about what they would be interested in doing．Then once you have an idea of what they want to do you can help them come up with fair prices．

Preferably you would want to only have your child working with people you know and trust, or in the least bit you could have your child pick a partner．That way with each of them carrying cell phones, even those without service can call 911, they will be much safer．

I was appreciating my family photos on my computer, admiring my two beautiful babies when I found a disturbing scene: my laptop was in almost all the pictures．There was my daughter, 8 months old, playing at my feet while I was typing on the couch．There was my son, with a big transformer, on my left arms．

I’d heard about the Internet addiction before, but I always thought it was something only limited to playing too much World of Warcraft (a computer game) day and night．Now, it seemed my Internet-habit is slowly but surely crossing the line．Sometimes I find myself up at midnight, surfing the Web while my family are sleeping．I read news, keep up with friends and write my blog … just for something to do．

It turns out that I’m not the only mama who is addicted to the computer．These moms are contributing to a growing global addiction．There’s a movement among psychiatrists (doctors who specialize in mental diseases) to recognize the Internet addiction as an official mental disorder．And a recent Stanford University national survey found that 14 percent of Internet users find it hard to stay away from it for several days at a time; 9 percent try to hide their —unnecessary Internet use from their loved ones; 8 percent admit they use the Web as a way to escape problems．

You’re likely not the kind of addict who doesn’t bathe and abuses drugs to help her stay up for more online time．You may have noticed, though, that going online has become a necessary part of your life, which, at least, means a box of clothes go unwashed．It may also mean you’re missing much time with you baby – something you probably do care about．

Most of the time, the ground feels solid beneath our feet. That's comforting. But it's also misleading because there's actually a lot going on underground. Masses of land (called plates) slip, slide, and bump against each other, slowly changing the shape of continents and oceans over millions and billions of years.

Scientists know that Earth formed about 4. 5 billion years ago. They also know that our planet was hot at first. As it cooled, its outermost layer, called the crust （地殼), eventually formed moving plates. Exactly when this shift happened, however, is an open question.

Now, an international group of researchers has an answer. They've found new evidence suggesting that Earth's crust started shifting at least 3.8 billion years ago. The new estimate is l. 3 billion years earlier than previous ones.

Not long before 3. 8 billion years ago, lots of small planets were hitting Earth, keeping its crust in a hot, melting state. After the hard crust formed, much of it sank at various times into the planet's hot insides. There, it melted before returning to the surface.

In some places, however, the crust never sank. One of the oldest such places is in Greenland, in an area called the Isua supracrustal (上地殼) belt. The rocky crust there is between 3. 7 and 3. 8 billion years old. The belt was once part of the seafloor, but now it is exposed to air.

The researchers recently took a close look at the Isua supracrustal belt. They noticed long, parallel cracks（裂縫）in the rock that have been filled in with a type of volcanic rock.

To explain this structure, the scientists propose that tension in the crust caused the seafloor to crack open long ago. Hot, liquid rock oozed from deep inside Earth to fill the cracks. Finally, the whole area cooled, forming what we see today.

That explanation, plus chemical clues inside the rock, suggests that the Isua supracrustal belt was once part of plate under the ocean, beginning around 3.8 billion years ago.

“It's a fantastic case of solving a jigsaw puzzle（拼圖）,”says one of the researchers. He notes that the puzzle was “a very difficult one because these rocks are all very old and have been badly ruined".

1.The underlined phrase “oozed from" in Paragraph 7 is closest in meaning to________.

A. filled up gradually

B. washed away quickly

C. flew out of slowly

D. broke through suddenly

2.What can we infer from the text?

A. The shapes of continents and oceans changed slowly.

B. The Earth's crust started shifting l.3 billion years ago.

C. The crust began to shift when the Earth was hot.

D. The hit from small planets made the Earth cool.

3.What do scientists know about the past of the Isua supracrustal belt?

A. It was once covered by hot, liquid rock.

B. It remained under the deep sea.

C. It stayed hot and sinking.

D. It kept moving slowly.

4.The text is mainly about________.

A. why the Earth cooled

B. how the Isua supracrustal belt formed

C. whether the ground beneath our feet is still

D. when Earth's crust began shifting
