Poor families in some countries spend as much as eighty percent of their money on food. Rising prices in recent months have created the worst food crisis(危机) in more than thirty years. The United Nations World Food Program says high food prices could push one hundred million people into hunger.
Nathan Childs is an expert on rice markets. He notes that the harvest for the latest growing season was the largest on record. But India, Vietnam and others have restricted exports(限制出口) to keep prices down at home and protect supplies.
Thailand’s agriculture minister says his country will never restrict rice exports. He told the Reuters news agency Thursday that Thailand has enough supplies to meet demand at home and for export.
Thailand is the world’s largest rice exporter. Recent signs of an increase in supplies have helped ease record prices for Thai rice. Prices rose last week above one thousand dollars a ton.
Vietnam, the second biggest exporter, has banned(禁止) exports until June. And Vietnamese officials have now warned that non-food traders who buy rice for speculation(投机活动)will be severely punished.
Some experts say speculation is a necessary part of market activity. But the head of the U.N. Environment Program blames it for the high food prices. “We have enough food on this planet today to feed everyone.” Achim Steiner told the Associated Press.
Earlier, a member of the United States Commodity Futures Trading Commission didn’t accept the idea that speculators are the main cause. Bart Chilton blamed reduced harvests and grain supplies and the falling value of the dollar.
U.N. Secretary General Ban Ki-moon called heads of major international agencies to a meeting this week in the Swiss capital, Bern. He says high food prices could harm world trade, economic growth, social progress and political security.

Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts hardly lose their pumping power with age.
“We have found that the power of the male heart falls by 20-25 percent between 18 and 70 years of age.” said the head of the study, David Goldspink of Liverpool John Moores University in the UK. “Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70. one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the ageing process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender(性别)difference might just explain why women live longer than men,” said Goldspink.
They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on heahhy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.

B．women can replace the cells that enable the heart to beat
C．the female heart loses few of the cells with age
D．women never lose their pumping power with age
4. We can know from the passage that ______.
A．scientists are on the way to finding out why the male heart loses more of the cells
B．the reason why ageing takes a greater loss on the male heart has been found out
C．the team has done something to prevent the male from suffering the greater loss
D．wome over 70 could lose more heart cells than those at the age of 20
