外刊阅读——学会地道英语 香蕉会在2050年消失吗？
① It’s hard to turn down tasty bananas. 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.
② One reason for this is climate change. Scientists at the University of Exeter collected data from 27 countries 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.
③ However, if temperatures keep rising, this advantage will disappear. Tens of the countries, including India, the world’s biggest producer of bananas, will produce fewer bananas. By 2050, the fruit may die out.
④ Shouldn’t bananas grow more easily if it’s hotter outside? In fact, the perfect temperature range for growing bananas is between $24°\mathrm{C}$ and $32°\mathrm{C}$. If temperatures get too high, they will stop growing.
⑤ Diseases are another danger to bananas. Unlike other plants, the bananas we grow come from shoot cuttings (嫩枝扦插) rather than seeds. This means that all banana plants have the same genotype (基因型). In other words, if a disease is able to kill one plant, it could kill them all.
⑥ One serious disease is called Panama. Caused by fungus in the soil, it spreads easily. 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.
一、好词句深练
（一）根据语境用所给单词的适当形式填空
1. The cake Grandma makes is always so

（二）用方框中词的正确形式替换下列句子中的黑体部分(有一个词多余) $\boxed{\mathrm{change}\ \mathrm{serious}\ \mathrm{disappear}}$
1. The dinosaur species graduallydied out millions of years ago.
2. The doctor is working tirelessly to find a cure for thedeadly disease.
（三）根据所给汉语, 完成下列句子

（四）仿写句子

2. Caused by fungus in the soil, it spreads easily. (过去分词短语作原因状语)

解析
【解析】
一、好词句深练
（一）词形转换
1. 此处作表语修饰名词cake，需将动词taste变为形容词tasty，意为“美味的”。
2. 此处修饰名词comedies，需将名词Britain变为形容词British，意为“英国的”。
3. 此处作主语指种植园，需将动词plant变为名词plantation，意为“种植园”。
（二）词义替换
1. 句中died out意为“灭绝、消失”，对应方框内单词disappear，根据时间状语millions of years ago可知用一般过去时，填disappeared。
2. 句中deadly此处意为“严重的（致命的）”，对应方框内单词serious，修饰名词disease，填serious。
（三）完成句子
1. “换句话说”的固定英文表达为In other words，句首首字母大写。
2. “还没有”的对应表达为have yet to，后接动词原形，符合语境。
（四）仿写句子
1. 要求使用否定疑问句结构“Shouldn't + 主语 + 谓语 + 其他”，按照提示语义组合为：Shouldn’t we make a plan in advance to deal with flood disasters?
2. 要求使用过去分词短语作原因状语，“由钢铁制成”的过去分词短语为Made of steel，后接主句组合为：Made of steel, that box is too heavy for even four of us to move it.
二、阅读选择
1. 代词指代题：结合第1段末句“British scientists say that the fruit may disappear by 2050”，可知第2段的this指代“香蕉将在约30年后灭绝”，选B。
