The world economy has run into a brick wall. Despite countless warnings in recent years about the need to address a potential hunger crisis in poor countries and an energy crisis worldwide, world leaders failed to think ahead. The result is a global food crisis. Wheat, corn and rice prices have more than doubled in the past two years. And oil prices have increased more than three times since the start of 2004.These food-price increases, combined with increasing energy costs, will slow if not stop economic growth in many parts of the world and will even affect political stability. Practical solutions to these problems do exist, but we’ll have to start thinking ahead and acting globally.
Here are three steps to ease the current food crisis and avoid the potential for a global crisis. The first is to promote the dramatic success of Malawi, a country in southern Africa, which three years ago established a special fund to help its farmers get fertilizer and seeds with high productivity. Malawi’s harvest doubled after just one year. An international fund based on the Malawi model would cost a mere $10 per person annually in the rich world, or $10 billion altogether.
Second, the U.S. and Europe should abandon their policies of paying partly for the change of food into biofuels. The U.S. government gives farmers a taxpayer-financed payment of 51 cents per gallon of ethanol(乙醇) changed from corn. There may be a case for biofuels produced on lands that do not produce foods but tree crops, grass and wood products, but there’s no case for the government to pay to put the world’s dinner into the gas tank.
Third, we urgently need to weather-proof the world’s crops as soon and as effectively as possible. For a poor farmer, sometimes something as simple as a farm pond—which collects rainwater to be used in dry weather—can make the difference between a good harvest and a bad one. The world has already committed to establishing a Climate Adaptation Fund to help poor regions climate-proof vital economic activities such as food production and health care but has not yet acted upon the promise.
An international fund based on the Malawi model would _____ .

A.cost each of the developed countries $10 billion per year
B.aim to double the harvest in southern African countries in a year
C.decrease the food prices as well as the energy prices
D.give poor farmers access to fertilizer and highly productive seeds

With the second step, the author expresses the idea that ______ .

A.it is not wise to change food crops into gas
B.it is misleading to put tree crops into the gas tank
C.we should get alternative forms of fuel in any way
D.biofuels should be developed on a large scale

In the passage, the author calls on us to _______ .

A.slow down but not to stop economic growth
B.develop tree crops, grass and wood products
C.achieve economic growth and political stability
D.act now so as to relieve the global food shortage

The majority of Indian women wear a red dot (圆点) between their eyebrows. While it is generally taken as an indicator of their marital (婚姻的) status, the practice is primarily related to the Hindu religion. The dot goes by different names in different Hindi dialects, and “bindi” is the one that is most commonly known. Traditionally, the dot carries no gender restriction: Men as well as women wear it. However, the tradition of men wearing it has faded in recent times, so nowadays we see a lot more women than men wearing one.
The position of the bindi is standard: center of the forehead, close to the eyebrows. It represents a third, or inner eye. Hindu tradition holds that all people have three eyes: The two outer ones are used for seeing the outside world, and the third one is there to focus inward toward God. As such, the dot serves as a constant reminder to keep God in the front of a believer’s thoughts.
Red is the traditional color of the dot. It is said that in ancient times a man would place a drop of blood between his wife’s eyes to seal their marriage. According to Hindu beliefs, the color red is believed to bring good fortune to the married couple. Today, people go with different colors depending upon their preferences. Women often wear dots that match the color of their clothes. Decorative or sticker bindis come in all sizes, colors and variations, and can be worn by young and old, married and unmarried people alike. Wearing a bindi has become more of a fashion statement than a religious custom.
Why did people in India start wearing a red dot on their forehead?

A.To indicate their social rank.
B.To show their financial status.
C.To show their religious belief.
D.To highlight their family background.

What is the importance of the third eye in Hindu tradition?

A.To pay respect to God.
B.To stay in harmony with nature.
C.To see things with a subjective view.
D.To observe the outside world more clearly.

Why was red chosen as the original color of the bindi?

A.The red dot represented the blood of God.
B.Red stood for a wife’s love for her husband.
C.The word “bindi” means “red” in some Hindi dialects.
D.Red was supposed to bring good luck to a married couple.

Which of the following statements is true about the practice of wearing a bindi today?

A.Bindis are now used as a decorative item.
B.Bindis are worn anywhere on the face now.
C.Most Indian women do not like to wear bindis anymore.
D.Wearing a bindi has become more popular among Indian men.

A store that sells husbands has just opened in Ottawa where a woman may go to choose a husband from many men.
The store is comprised of 6 floors and the men increase in positive attributes(品质,特点)as the shopper goes up the flights. There is, however, a catch(陷阱). As you open the door to any floor you may choose a man from that floor, but if you go up a floor, you cannot go back down except to exit the building.
So a woman goes to the shopping center to find a husband. On the first floor the sign on the door reads: Floor 1—These men have jobs. The woman reads the sign and says to herself, “Well, that’s better than my last boyfriend, but I wonder what’s further up?”
So up she goes. The second floor sign reads: Floor 2—These men have jobs and love kids. The woman remarks to herself, “That’s great, but I wonder what’s further up?”

And again she heads up another flight. The fifth floor sign reads: Floor 5—These men have jobs, love kids, are extremely good-looking, help with the housework and have a strong romantic character. “Oh, mercy me! But just think…what must be awaiting me further on?”
So up to the sixth floor she goes. The sixth floor sign reads: Floor 6 –You are visitor 3, 456, 789,012 to this floor. There are no men on this floor. Thank you for shopping Husband Mart and have a nice day.

Let children judge their own work A child learning to talk does not learn by being corrected all the time: if corrected too much, he will stop talking . He notices a thousand times a day the difference between the language he uses and the language those around him use. Bit by bit, he makes the necessary changes to make his language like other people's. In the same way, children learning to do all the other things without being taught, such as walking, running, climbing, riding a bicycle. They compare their own performances with those of more skilled people, and slowly make the needed changes.
But in school we never give a child a chance to find out his mistakes and correct them for himself. We do it all for him. We act as if we thought that he would never notice a mistake unless it was pointed out to him, or correct it unless he was made t0.Let children help each other if they want--what this word says, what the answer is to that problem, whether this is a good way of saying or doing this or not
If it is a matter of right answer, as it may be in mathematics or science, give him the answer book Let him correct his own paper. Why should we teachers waste time to such routine work? Our job should be to help the child when he tells us that he can't find the way to get the right answer. Let the children learn what all educated persons must some day learn, how to measure their own understanding, how to know what they know or do not know.

As for older people, some of the applications(应用程序)are hard to use because they didn't grow up with them. They don't have simple models of how it should work. They don't know what to do when it doesn't work.
I think there is huge potential, so I have designed some for them. The ability to connect to friends, who remember the same movies, news and music, is really important, especially as people get older. They end up in retirement homes and they aren't always close to their friends. Allowing the network to help them connect with friends and family members is a really powerful thing.
My wife likes using the Internet, although it took me years to get her to use e-mail. She was born with normal hearing, but lost it when she was three years old. She was totally deaf for many years until 53 when she got ear implants(移植).They work really well. That is a big change for her. Before then, her friends couldn't call her on the phone, so they insisted that she use e-mails to communicate with them.
The younger people don't even think of this as technology. It's just there, and they use it .There's been a very interesting change in communication styles between the old and the young .A woman named Sharryturkle wrote about this phenomenon(现象).There are some kids who are now in their teens and are tending not to make phone calls. And they think of e-mail as old-fashioned and slow.
The reason why teens don't make phone calls seems to be that they don't know what to say. When they call they often pause for a while. On the other hand, texting is considered proper, and it's OK if you don't answer. You might have been distracted(心烦意乱的).It's not considered rude, but it's considered unusual if you're in this kind of voice conversation and simply stop talling.

A British-designed electronic newspaper which is made of plastic and no larger than a table mat(垫子) is to enter the market next year. The new newspaper was conceived(想出) by Cambridge University scientists. They came up with the idea of replacing silicon chips (硅片) with plastic ones. it is being developed by Plastic Logic, a company based in Dresden, Germany.
"It looks just like a table mat, and is as light as a magazine. But you can download hundreds of newspapers at the touch of a button, and read them quite safely," the BBC reported on its website.
The plastic paper is produced in a safe "clean room" at the Plastic Logic factory, which opened last month as the world's first plastic-electronics factory. Every part of the product, from the screen to the electronics, is made of plastic. And it is described by engineer Dean Baker as "top quality". Baker says the plastic newspaper could help solve the problem of waste material associated with traditlional newspapers.
"There's a huge amount of waste . We have paper distributed(分发) all over the country each day and then thrown into the bin. This doesn't need to happen any more. All of the copies could be made electronically and stored on a single e-reader with the appearance of paper." he says.
