【D7】
A disease that threatens the world’s most popular fruit, the banana, has arrived in Latin America. As a result, officials in Columbia have declared a state of emergency. Bananas are among the most important food crops in the world, along with wheat, rice, and com. That information comes from the United Nations (UN). Five years ago, the UN warned that a disease called Tropical Race 4 or TR4, could destroy much of the world’s banana crop.
The disease first appeared in Asia in the 1990s. It later spread to Africa and the Middle East. There are as many as 1,000 kinds of bananas grown in more than 150 countries. The TR4 disease only affects the most popular and common kind of banana—the Cavendish. It is easier and more cost-effective for growers to produce just one kind of banana. Growers in Colombia and many other places choose Cavendish bananas. This variety can be shipped to countries around the world without ripening too quickly. Banana industry watchers say there is still time to find another kind of banana to grow. Randy Ploetz is a retired scientist from the University of Florida. He studied tropical plant diseases. He said of the recent spread of TR4, "I don’t think it’s going to impact the availability of the Cavendish in supermarkets anytime soon. " He added that Asian countries affected by the TR4 disease plant different kinds of Cavendish or move to uninfected farmlands. But those bananas are not as productive, and they later become infected, too. In Colombia, officials are taking special measures to stop the disease from spreading. Officials have removed plants infected with the disease and covered soil with black plastic sheets, to prevent spread of the disease.
Officials have also set up controls at entrances to affect banana farms, where they disinfect the trucks that travel between the farms and ports.
Gert Kema is a plant scientist who studies bananas. He agrees that the banana industry needs to diversify. He says there are many types of tomatoes and peppers grown around the world. For example, banana should be no different.
选项
答案
cost-effective

根据原文可知,TR4疾病只影响最流行和最常见的香蕉品种——卡文迪什香蕉。对种植者来说,只种植一种香蕉更容易,成本更低。因此,填入more cost-effective。
