核心素养测评三十五 Module 5 Cloning
Ⅰ. 阅读理解
A
In the 1950s, Central American commercial banana growers were facing the death of their most economical product, the Gros Michel banana. Now it’s happening again to its successor—the Cavendish.
With its easily transported, thick-skinned and sweet-tasting fruit, the Gros Michel banana plant dominated the plantations of Central America. United Fruit, the main grower and exporter in South America at the time, mass-produced its bananas in the most efficient way possible: it cloned shoots from the stems of plants instead of growing plants from seeds, and cultivated them in densely packed fields.
Unfortunately, these conditions are also perfect for the spread of the fungus(真菌), which attacks the plant’s roots and prevents it from transporting water to the stem and leaves. The TR-1 strain of the fungus was resistant to crop sprays and travelled around on boots or the tyres of trucks, slowly infecting plantations across the region. In an attempt to escape the fungus, farmers abandoned infected fields, flooded them and then replanted crops somewhere else, often cutting down rainforest to do so.
Their efforts failed. So they searched for a variety of bananas that the fungus didn’t affect. They found the Cavendish, which wasn’t as well suited to shipping as the Gros Michel, but its bananas tasted good enough to keep consumers happy. Most importantly, TR-1 didn’t seem to affect it. In a few years, United Fruit had saved itself from bankruptcy by filling its plantations with thousands of the new plants. However, the Cavendish banana itself is far from safe. In 2015, the exports of Cavendish bananas had dropped by 46 per cent thanks to a combination of another strain of the fungus, TR-4, and bad weather.
Racing against the inevitable, scientists are working on solving the problem by genetically modifying the Cavendish with genes from TR-4-resistant banana species. Researchers have successfully grown two kinds of modified plants which have remained
11
resistant for three years so far. But some experts think this is just a complicated version of the same temporary solution the original Cavendish provided. If the new bananas are planted in the same monoculture(单种栽培) as the Cavendish and the Gros Michel, the risk is that another strain of the disease may rise up to threaten the modified plants too.
【文章大意】本文主要讲了香蕉种植者不断提高香蕉抵御病毒的能力, 然后作者提到了转基因香蕉。

【知识拓展】长难句分析
United Fruit, the main grower and exporter in South America at the time, mass-produced its bananas in the most efficient way possible: it cloned shoots from the stems of plants instead of growing plants from seeds, and cultivated them in densely packed fields.
分析: 句子主语是United Fruit。the main grower and exporter in South America at the time是United Fruit的同位语。谓语是mass-produced。宾语是its bananas。in the most efficient way possible作状语。冒号后面对way作了具体的解释说明。
翻译: United Fruit, 那时南美主要的种植者和出口者, 以最有效的方法大规模生产香蕉: 它从植物的茎上克隆幼苗, 而不是用种子育苗, 然后在密集的田地里种植它们。

Are some people born clever, and others born stupid? Or is intelligence developed by our environment and our experience? Strangely enough, the answer to these questions is yes. To some degree our intelligence is given to us at birth, and no amount of education can make a genius out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich and varied surroundings. Thus the limits of person’s intelligence are fixed at birth, but whether or not he reaches those limits will depend on his environment. This view, now held by most experts, can be supported in a number of ways.
It is easy to show that intelligence is to some degree something we are born
11
with. The closer the blood relationship between two people, the closer they are likely to be intelligent. Thus if we take two unrelated people at random from population, it is likely that their degree of intelligence will be completely different. If, on the other hand, we take two identical twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth. Imagine now that we take two identical twins and put them in different environments. We might send one, for example, to a university and the other to a factory where the work is boring. We would soon find differences in intelligence developing, and this indicates that environment as well as birth plays a part. This conclusion is also suggested by the fact that people who live in close contact with each other, but who are not related at all are likely to have similar degree of intelligence.
