【正文】 ccording to a new study, a disease caused by a powerful fongus(真菌） is killing the Cavendish banana, which accounts for 99% of the banana market around the globe. The disease, called Tropical Race 4(TR4),has affected banana crops in southeast Asia for decades. In recent years, it has spread to the Middle East and the African nation of Mozambique. Now experts fear the disease will show up in Latin America, where the majority of the world?s bananas are grown. Once a banana plant is infected with TR4, it can?t get water and nutrients. TR4 lives in soil, and can easily end up on a person?s boots. If the contaminated(污染） boots are then worn on a field where Cavendish bananas are grown, the disease could be transferred. “Once a field has been contaminated with the disease, you can?t grow Cavendish bananas there anymore.” scientist Randy Ploetz says. Cavendish bananas are produced in mass quantities and are popular among consumers. But once one banana plant gets infected(感染 )， it just runs like wildfire through that entire plantation. One solution to solve the problem, Ploetz says, is to try to develop new bananas that can resist TR4. “It really needs to be done, but we don?t have it yet.” He notes that we still have time before we need to worry about the Cavendish banana disappearing. 24.

Researchers at Queen Mary University of London said the experiments, often used to test the intelligence of apes (猿 )and birds， showed for the first time that some insects are up to the task，and can also pass skills on through several generations. The findings add to the evidence suggesting the ability for “culture spread” the ability to learn and pass on knowledge and skills may not be exclusive to humans. In the research, published in the journal PLOS Biology on Tuesday, the scientists were abl
