What will we be eating in the future? Here are the top factors that will be affecting the food that ends up on our tables in the new century.
Genetically engineered food Many crops are already genetically engineered,often to produce more food,fight against pests or improve nutrition But concern is growing over the lasting effects of changing nature.While existing research has found little harm in genetic,engineering,a recent study found the flower powder of a genetically engineered corn can kill the normal butterfly.This finding made many people nervous and brought attention to the topic.
Dining out Americans are increasingly eating meals away from home,both in sit―down restaurants and in fast food outlets.In the 1ast decade alone there was a 14 percent decrease in the number of meals eaten at home.At the same time,restaurants are just beginning to really open their doors 0n the Internet.Websites exist to make restaurant reservations(预约),view menus,and get tips from your favorite chefs.The dining Out trend and the demand for high-quality,chef-prepared food have encouraged chefs to spend time out of the.kitchen--teaching classes,appearing on TV,and writing cookbooks.
Eating in Eating in doesn’t always mean cooking.Ready-made meals and frozen food sold in supermarkets taste better all the time.Restaurants are offering neatly packaged “food to go”,and meals can be ordered over the Internet.Cooking is not as much as a necessity,as it is a hobby,a special treat.Home cooks are looking to more than just mom’s food,and want to make food they try in restaurants.
Agriculture Although American farmers have been hit hard recently by bad weather, low prices and decreasing government help,they can increase grain production not using old farm methods.

健康环保类文章阅读技巧:
健康环保类文章常是介绍科学知识、生活常识和环境保护方面的短文。阅读此类短文要以现象或事物为中心进行思考,理解现象产生的原因、条件和客观规律等。同时要抓住事物的特征、用途和相互关系等。科普环保类文章一般为说明文,从结构上看大致可分为三个部分:
第一部分一般是文章的首段,主要用来提出文章的主题,即文章想要阐述、说明的主要内容;
第二部分是文章的主体,可由若干个段落组成,对文章的主题进行展开说明;
第三部分是结尾段,对文章的主题进行归纳总结。这类文章多用一般现在时,而且一般多使用客观性词语表述。有时为了强调客观性,也常使用被动语态。
从近几年的考试题来看,科普环保类的文章越来越与人们的实际生活相接近。由于此类文章缺乏故事情节,很多同学对此类文章感到费解。但一般的科普类文章都是就事论事,需要逻辑推理和想象的时候较少,因此此类阅读题也没有同学们想象中的那么难,只要多加训练,就能较好地答题。
【阅读策略】
1、概要(Summarizing):
阅完材料后,将所阅材料浓缩,摘要,做出所阅材料的书面或口头梗概。
2、组织(Organization):
阅读后根据阅读内容,识别观点、人物、事件之间的关系以及文章的结构关系。如:时间关系、比较或对比关系、相关关系及因果关系等。

Flu (which is short for influenza) is a highly infectious disease, the cause of which is a very tiny organism known as a virus. Several types of flu are recognized, depending on the type of virus that causes the disease.

Flu can often cause problems in breathing, and general infection of the lung. With elderly and weak people, these added complications often produce serious results. The virus, if not properly treated, can weaken the body so that patient may develop more serious illnesses, such as pneumonia and bronchitis. When people catch flu, they often complain of a headache or a sore throat. They usually have a fever and their temperature rises from the normal 37℃ (98.6) to about 39.5℃ (103). Sometimes a person has a dry hacking cough and aching joints.

Today many doctors use drugs that fight the disease. And scientists have also developed vaccines that help to prevent it. If the patient has proper treatment, and complete rest in bed, the virus is normally beaten within a week to ten days.

How does flu spread so quickly? When the infected person breathes out, sneezes or coughs, he gives out droplets of moisture in the breath from his mouth or nose. These remain in the air for some time. Flu viruses are present in these droplets. If a person sneezes in a crowd or poorly ventilated place, such as a lift, viruses can easily be carried from an infected person to a healthy person. This is known as droplet infection. The healthy person will breathe in the viruses given out by the infected person.

There are three main types of virus that cause flu, which are called type A, B and C. type A is the most powerful of the three, and undergoes minor changes in its genetic material every few years. The new form of the virus is called a strain. The new strain is not affected by the current vaccines. It is said to be “resistant” to them. So doctors must be continually producing new vaccines to combat the new strains of virus.
