You might have noticed that the cost of food has gone up.In fact the price of wheat and rice has nearly doubled in the past few years.It’s thought that right now,850 million people—that’s more than 10 times the population of the UK—are short of food because it’s too expensive or there’s not enough of it.
The price of basic food such as wheat and corn has stayed the same for quite a long time,about 30 years.But as the world’s population is getting bigger,there’s more pressure to feed more people,plus there’s less land and water to go round.
Another reason is climate(气候)change.Droughts and floods make it hard to grow crops like rice and grain.The price of oil has gone up and that makes it more expensive for farmers to run their tractors and to transport the food they make.And lots of fields are being used to grow crops to make other things that can’t be eaten—which is bad news for hungry people.
The main losers are poor people who live in cities in poor countries,who are facing higher prices for food.Some people are doing well out of the food crisis(危机) though.Farmers in rich countries like the US,Canada and Australia are getting record prices for their harvests.
World leaders are meeting in the Italian capital Rome to talk about the problem of rising food prices.Some countries are helping out with the cost of foods and international aid agencies have called for more money for food production in poor countries.

Lana: I read a report. It said that Dr. Ian Wilmut successfully cloned a lamb* named Dolly from a grown-up sheep. So people call him the “father” of Dolly.
Tony: In fact, the word “clone” means to produce the “same” animal by taking cells* from a
grown-up one. I think, if we know how to do cloning, we need only to keep a small number
of sheep, cows or horses.
Lana: What’s more, these days some people even want to clone humans. They have asked: Can we
clone ourselves?
Tony: It seems interesting. But do you think it possible to do that?
Lana: No, impossible! First, I think we cannot clone a dead person, because the cells in his body are dead already.
Tony: Then can we clone a living person?
Lana: Again no! You might clone yourself one after another, but it is only a copy, not a real you. It is only something, not a “human”.
Tony: Well, you mean that it is not a real human.
Lana: True enough! I think Dr. Wilmut would most like to make better animals, and it has nothing to do with human cloning.
