Question

By 2050 there will have been an extra 2.5 billion people on earth. And what will they eat?
To solve the problem, we should have to double our food production. We can also develop a diet of algae（海藻）, insects and meat grown in laboratories.
Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops. They are already eaten widely in Japan and China and they are eaten by almost everything from shrimps to blue whales. They can fix CO2 in the atmosphere and provide fats and sugars.
Man-made meat looks like meat, feels like meat and it is meat, although it’s never been from a living, breathing animal. Instead, it is grown from cells in big containers. Moreover, studies show that producing man-made meat will use far less water, energy and land.
China has developed “green super rice”, a series of rice types which produce more grain and have stronger ability to fight against floods, salty water, insects and disease. We used traditional plant breeding（作物育種）techniques to cross-breed more than 250 rice types. Green super rice, which is enough to feed an extra 100 million people, will be planted widely in the coming years.
Insects like ants are not on most European menus but at least 1,400 kinds are eaten across Africa, Latin America and Asia. Now, with rising food prices and worldwide land shortages, such insects are getting more and more popular. Not only are many insects rich in protein（蛋白質(zhì)）, low in fat and high in Ca and Fe, but insect farms need little space. And they can grow well on paper, algae and industrial wastes

      includes no more than 250 rice kinds
   4. D.
      was developed with new technologies
4. 4.
   What can we learn from the passage?
   1. A.
      Green super rice is delicious but high in price
   2. B.
      In Asia about 100 million people may be faced with food shortages
   3. C.
      Man-made meat doesn’t look like meat but has the same taste as real meat
   4. D.
      One of the reasons why many people begin to eat insects is their rich food value

試題分析：文章主要講述的未來的生活。到2050年，地球上的人口將增加25億。到那時，地球該怎樣養(yǎng)活這么多人呢？食物的產(chǎn)量不僅要翻倍，同時，還要尋找其它的食物來源。
1.根據(jù)“To solve the problem, we should have to double our food production. We can also develop a diet of algae（海藻）, insects and meat grown in laboratories.”可知，人們需要把食物的產(chǎn)量翻倍，也可以開發(fā)其它食物來源。故選D。
2.根據(jù)“Algae can grow very quickly at sea, in polluted water and in places that would normally kill food crops.”可知，海藻的生命力極強，能夠在海水里、污水中和其它農(nóng)作物不能正常生長的地方。故選A。
3.根據(jù)第四段“produce more grain and have stronger ability to fight against floods, salty water, insects and disease”可知，綠色超級水稻有更強的能力來抵抗洪水、鹽水、昆蟲和疾病。故選B。
4.根據(jù)最后一段的“Not only are many insects rich in protein（蛋白質(zhì)）, low in fat and high in Ca and Fe...”可知，食用昆蟲的原因之一是，它們富含營養(yǎng)成分。故選D。
