Experts say some farming activities arc seriously damaging Earth’s environment. Bad farming methods can damage soil, forests and water supplies. They also have caused some plants and animals to disappear.
Two groups now say that bad farming methods are threatening the ability of farmers to produce enough food to feed the world population in the future. The groups used satellite images, maps and modern equipment to study the effect of agriculture on the environment. The study found that the destruction of soil is widespread. Important organic nutrients are being removed from farmland.
Agriculture uses seventy percent of the freshwater in the world each year. The study found that many farmers are wasting water supplies. In addition, chemicals designed to protect crops may pollute waterways.
The report also says as much as thirty percent of the world’s forests have been cut down so the land could be used for agriculture. This has led to a severe loss of wildlife and their environments.
Questions 23 to 25 are based on the passage you have just heard.
23. Which is not mentioned in the passage as an aspect that farming activities are damaging?
24. How can the group carry out their studies?
25. According to this passage, why the farming activities can affect the animals?
选项
A、By forcing them farming.
B、By affecting the quality of soils.
C、By adding chemicals and pollute the waterways.
D、By affecting the environments they live in.
答案
D
解析
推理题。本文最后提到“This has led to a severe loss ofwildlife and their environments.”即农业活动最终会影响居住环境从而导致了动物的减少,因此D选项正确。C项尽管原文也提到,但也是包含在D项中,对水域的污染也是对环境的污染。
