An old man was going home late one night with his horse and cart after a day’s hard work. When he was not far from his house, the light on the cart went out. He tried but could not mend (修理) it. He was near his home, and so he went along the road without a light. When a policeman saw this, he stopped the old carter.

“Where is your light?” asked the policeman. “No man may take a cart along the road at night without a light. You know that. You have broken the law (法律).”“I had a light, but it has just gone out,” said the old man.

“I don’t believe that story,” said the policeman. He took out a book and got ready to write. What’s your name and where do you live?” he asked.

“Please don’t take my name,” said the old man. “My home is just there. You can see it from here. I had a light nearly the whole way. I haven’t come far without a light.”

“You came all the way without a light. What’s your name?”

The carter quickly took the policeman’s hand and put it down on top of the light. The light was still hot and burnt the policeman’s hand. The policeman jumped and he was very angry. “Now, what do you think?” said the carter. “Did I come all the way without a light?”

The United States is suffering its worst drought (干旱) in almost sixty years. The National Climatic Data Center also says high temperatures in June added to the warmest twelve-month period on record. Record-keeping began in 1895. The drought map showed that conditions improved in the Southeast in June compared to May. But the drought is expected to continue in large parts of the country. Last week, Agriculture Secretary Tom Vilsack met with President Obama. Mr Vilsack says the drought has seriously influenced some crops, such as corn and soybeans (大豆). And the United States is the world's leading producer. 

The drought has made prices of com and soybeans increase. Both of them are used in food production and for animal feed. Last week the United Nations Food and Agriculture Organization reported that corn and wheat prices increased by 20% over the past three weeks.

In the United States, farmers may quickly reduce the size of their animals rather than pay higher feed prices to keep them. That increased supply of meat would reduce meat prices in the short term. But those prices could increase in several months.

Mr Vilsack says the effect of the drought is hard to predict(预测). Some areas are getting rain, and drought-resistant (抗旱的) seeds have helped crops grow well in some areas.
