Question

【题目】 You'd better eat a banana while you still can. British scientists say that the fruit may disappear by 2050.

One ______ is climate change. Scientists from the UK collected data(数据) from 27 countries and regions that produced 86 percent of the world's bananas. They found that climate change has improved growing conditions in 21 of these countries and regions. _______ ,if temperatures keep rising, this advantage will disappear. The perfect temperatures range for growing bananas is between 24℃and 32℃. If temperatures get too high, they will _____ growing.

Diseases are another danger to bananas. Unlike other crops, the bananas come from shoot cuttings rather than seeds. It means that all bananas plants have the _______ genotype(基因型). If a disease is able to kill one plant, it could kill them all.

One serious disease is called Panama Disease. Caused by a fungus(真菌) in the soil, it can easily ______ If one banana plantation suffers from the disease, it will take 30 years before it can grow bananas again. Scientists have yet to find a cure to fight Panama Disease.

【5】B

【解析】

本文主要分析了在2050年前香蕉会消失的原因，如：气候的改变和疾病。

【1】句意：一个原因是气候变化。

reason理由；example例子；advantage优势，根据上文British scientists say that the fruit may disappear by 2050. 英国科学家说，这种水果可能在2050年消失。可知本句在解释将要消失的原因，故选A。

【2】句意：然而，如果温度持续上升，这一优势就会消失。

Besides除了；Suddenly突然；However然而，根据上文They found that climate change has improved growing conditions in 21 of these countries and regions. 他们发现，气候变化改善了其中21个国家和地区的生长条件。与下文if temperatures keep rising, this advantage will disappear. 如果温度持续上升，这一优势就会消失。可知上下文属于转折关系，故选C。

【3】句意：如果温度太高，它们就会停止生长。

start开始；keep保持；stop停止，根据上文The perfect temperatures range for growing bananas is between 24℃and 32℃.可知种植香蕉的最佳温度范围在24℃至32℃之间，If temperatures get too high如果温度太高，可推断出它们就会停止生长。故选C。

【4】句意：这意味着所有香蕉植物都有相同的基因型。

same一样；strong强壮；simple简单，Unlike other crops, the bananas come from shoot cuttings rather than seeds. 与其他作物不同的是，香蕉来自扦插而不是种子。可知所有香蕉植物都有相同的基因型，故选A。

【5】句意：由土壤中的真菌引起的疾病，如果一个香蕉种植园患有这种疾病，它很容易传播。

disappear消失；spread传播；change改变，根据句意，可知这种真菌引起的疾病很容易传播，故选B。
