题文
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（作物育种）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.
小题1:In order to exist in the future, people have to _______.A．move to other planetsB．produce rain in laboratoriesC．build new laboratories for food researchD．increase the food production or look for other food sources小题2:From the second paragraph we know that _______A．algae have a strong life forceB．few people eat algae nowC．algae have few values for human beingsD．algae can pollute our environment小题3:Green super rice _______A．has to be watered with salty waterB．can grow even in a bad environmentC．includes no more than 250 rice kindsD．was developed with new technologies小题4:What can we learn from the passage?A．Green super rice is delicious but high in price.B．In Asia about 100 million 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. 题型：未知难度：其他题型
答案
小题1:D
小题2:A
小题3:B
小题4:D
解析
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。
小题1: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。
小题2: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。
小题3: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。
小题4: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。
考点
据考高分专家说，试题“By 2050 there will h.....”主要考查你对 [日常生活类阅读 ]考点的理解。日常生活类阅读
日常生活类阅读的概念：
日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。
日常生活类阅读题答题技巧：
【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。
【备考提醒】
为了保证较高准确率，建议同学们做好以下几点：
1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。
2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
