短缺可可豆

首页 > 试题列表 > 单题解析

21758. （2020•高新一中•一模） Most of us probably live without vegetables,but how about a world without chocolate？Now that would be possible!According to chocolate makers it could happen if we don't act soon.
There are two main causes of the chocolate shortage（短缺）-chocolate's growing popularity and less production of cocoa（可可豆），the plant from which chocolate is made.With more and more people in India and China loving chocolate,not much can be done about the first cause.
Therefore,the only thing we can do is to increase cocoa production.However,new plant diseases and little rain in Ivory Coast and Ghana,the world's largest producers,have reduced cocoa production by 40 percent in the past 10 years.What's worse,many cocoa farmers in Africa and other cocoa producing countries like Indonesia and Venezuela are changing to easier-to-grow crops such as corn or rubber（橡胶）．This way,the farmers can make more money.
To prevent more farmers from changing,researchers at the newly opened International Cocoa Control Center,in the UK，are trying to create new cocoa plants that are stronger and faster growing.But first they must make sure the new plants are safe to grow.This takes a long time.
First,each new plant is stored at the Control Center for six months to make sure it is healthy.It is then planted in the Center's fields,studied and tested for another two years.Only after scientists are certain that they're disease free,will the plants be sent to farmers in West Africa or wherever else they are needed.
To create new stronger types of cocoa,scientists at the Control Center are combining（结合） the best parts from different cocoa plants.Though the world is facing a serious chocolate shortage,there is now hope!
41．The first paragraph tells us that the world could soon be without vegetables.
42．Chocolate has become more popular in China and India.
43．Cocoa farmers are choosing to grow rubber,corn and bananas because these crops can make them more money.
44．It takes scientists at the Control Center 3 years to make sure a cocoa plant is safe to grow.
45．One of the purposes of the Cocoa Control Center is to produce stronger types of cocoa plants.       ．
