Question

【题目】 ①It's hard to turn down a tasty banana. They taste good and you don't have to wash them before eating them. However, British scientists say that the fruit may disappear by 2050.

②One reason for this is climate（气候）change. Scientists at the University of Exeter collected data （数据）from 27 countries and regions that produce 86 percent of the world's bananas. They found that climate change has improved growing conditions in 21 of these countries. In the past 60 years, the average yield （平均产量）has reached 1. 37 tons of bananas per hectare （公顷）.

③However, if temperatures keep rising, this advantage will disappear. Ten of the countries, including India, the world5s biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out.

Shouldn't bananas grow more easily if it*s hotter outside? In fact, the perfect temperature range for growing bananas is between 24 and 32 "C. If temperatures get too high, they will stop growing.

Diseases are another danger to bananas. Unlike other crops, the bananas we grow come from shoot cuttings （茎段）rather than seeds （系中子）. This means that all banana plants have the same genotype. In other words, if a disease is able to kill one plant, it could kill them all.

⑥One serious disease is called Panama. Caused by fungus （真菌）in the soil, it spreads easily. It has spread across South Asia, Africa, the Middle East, and Australia. If one banana plantation suffers from the disease, it will take 30 years until it is able to grow bananas again. Scientists have yet to find a cure for this disease.

B.Panama has killed all the bananas in some areas like South Asia.

C.The higher the temperature is, the better bananas will grow.

D.Bananas grow from shoot cuttings instead of seeds.

【3】What does the passage mainly talk about?

【解析】

文章大意：英国科学家称香蕉这种水果可能在2050年消失。原因之一是气候的变化。然而,如果温度继续上升,这种优势将会消失。其中10个国家，包括世界上最大的香蕉生产国印度，将减少香蕉的产量。到2050年，这种水果可能会灭绝。事实上，种植香蕉的最佳温度范围是在24到32摄氏度之间。如果温度太高，香蕉就会停止生长。疾病是香蕉的另一个危险。一个严重的疾病叫做巴拿马。科学家尚未找到治疗这种疾病的方法。

【1】

词义猜测题。根据文中“However, British scientists say that the fruit may disappear by 2050.

②One reason for this is climate（气候）change.” 然而，英国科学家称这种水果可能在2050年消失。这是气候的原因之一(气候)的变化。可知，下划线的单词“this”②段指香蕉将在30年内灭绝。故答案为D。

【2】

理解推断题。根据文章内容可知，在过去的60年里,平均收益率(平均产量)已达到1，37吨香蕉每公顷(公顷)。我们可以推断，在过去的几年里，香蕉的平均产量增加了。故答案为A。

【3】

主旨大意题。根据文章内容可知，英国科学家称香蕉这种水果可能在2050年消失。原因之一是气候的变化，疾病是香蕉的另一个危险。一个严重的疾病叫做巴拿马。科学家尚未找到治疗这种疾病的方法。这篇文章主要讲了香蕉消失的原因，故答案为C。

【4】

篇章结构题。根据文章内容可知，第一段，英国科学家称香蕉这种水果可能在2050年消失。主要有两个原因，原因之一是气候的变化，2,3,4段介绍的；另一个原因是疾病，疾病是香蕉的另一个危险，是后两段，故选项B是正确的，故答案为B。
