题目内容
15.By 2050there will have been an extra 2.5billion 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 CO2in 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(作物育种)techniques to cross-breed more than 250rice types.Green super rice,which is enough to feed an extra 100million people,will be planted widely in the coming years.
Insects like ants are not on most European menus but at least 1,400kinds 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(蛋白质),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.
63.In order to exist in the future,people have toD.
A.move to other planets
B.produce rain in laboratories
C.build new laboratories for food research
D.increase the food production or look for other food sources
64.From the second paragraph we know thatA
A.algae have a strong life force
B.few people eat algae now
C.algae have few values for human beings
D.algae can pollute our environment
65.Green super riceB
A.has to be watered with salty water
B.can grow even in a bad environment
C.includes no more than 250rice kinds
D.was developed with new technologies
66.What can we learn from the passage?D
A.Green super rice is delicious but high in price.
B.In Asia about 100million people may be faced with food shortages.
C.Man-made meat doesn't look like meat but has the same taste as real meat.
D.One of the reasons why many people begin to eat insects is their rich food value.
分析 文章主要讲述的未来的生活.到2050年,地球上的人口将增加25亿.到那时,地球该怎样养活这么多人呢?食物的产量不仅要翻倍,同时,还要寻找其它的食物来源.
解答 63-66 DABD
63.答案D.细节理解题.根据"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,人们需要把食物的产量翻倍,也可以开发其它食物来源.故选D.
64.答案A.细节理解题.根据"Algae can grow very quickly at sea,in polluted water and in places that would normally kill food crops."可知,海藻的生命力极强,能够生长在海水里、污水中和其它农作物不能正常生长的地方.故选A.
65.答案B.细节理解题.根据第四段"produce more grain and have stronger ability to fight against floods,salty water,insects and disease"可知,绿色超级水稻有更强的能力来抵抗洪水、盐水、昆虫和疾病.故选B.
66.答案D.细节理解题.根据最后一段的"Not only are many insects rich in protein(蛋白质),low in fat and high in Ca and Fe…"可知,食用昆虫的原因之一是它们富含营养成分.故选D.
点评 新闻报道解题技巧:第一步"看标题信息",类似作文审题;而"揣摩记叙类型",则是指阅读的审题目标要比作文单一.即通过对题意的揣摩,要能辨出该文的记叙对象,是人物新闻还是事件新闻,是消息还是通迅. 第二步"抓记叙要素",这是由文体特点决定的.因为新闻的内容,无论哪种类型,一般都离不开人物、时间、地点和事情的起因、发展、结果这六个要素. 第三步"理行文线索",即领悟文章的脉络、顺序,目的是理清作者的行文思路,借此可准确地划分全文的段落层次.针对考纲当中C层级的分析综合"分析语言特色,把握文章结构,概括中心意思"的考点.第四步"辨叙述方式",即辨析文本主要采用的叙述方式,消息一般都是采用"倒金字塔"式(即先说结果,再说重要事实,最后说次要内容),这跟一般的记叙文不同.而通迅的叙述方式就比较灵活多变,有顺叙、倒叙,中间或许还会有插叙、补叙.
