Organic foods are produced according to certain production standards, meaning they are grown without the use of conventional pesticides, or chemical fertilizers and that they were processed without food additives. Livestock are raised without the routine use of antibiotics(抗生素)or growth hormones. In most countries, organic produce must not be genetically modified. They may also be required to be produced using energy-saving technologies and packaged using recyclable materials when possible.
Early consumers interested in organic food would look for non-chemically treated, fresh or minimally processed food.
They mostly had to buy directly from growers: “Know your farmer, know your food” was the motto. Personal definitions of what constituted ( 组成)“organic” were developed through first-hand experience: by talking to farmers, seeing farm conditions, and farming activities. Historically, organic farms were relatively small family-run farms — which is why organic food was once only available in small stores or farmers’ markets.
However, since the early 1990s organic food has had growth rates of around 20% a year. As of April 2008, organic food accounts for 1 - 2% of food sales worldwide. Currently organic food production is legally regulated. Many countries require producers to obtain organic certification in order to market food as organic.
Several studies have attempted to examine and compare conventional and organic systems of farming. The general consensus(共同看法)is that, in the short term, organic farming is less damaging for the following reasons:
● Organic farms do not release synthetic pesticides (合成农药) into the environment — some of which have the potential to harm soil, water and local wildlife.
● Organic farms are better than conventional farms at keeping diverse ecosystems, i.e., populations of plants and insects, as well as animals.
● Organic farms are more energy efficient and produce less waste.
Another report published in March 2008 by The Organic Center claims that organic food is on average 25% more nutritious than conventional food.
However, many critics believe that the increased land needed to farm organic food could potentially destroy the rainforests and wipe out many ecosystems. And organic products cost 10 to 40% more than similar conventionally produced products. Processed organic foods in supermarkets are 65% more expensive.
1. Early consumers knew what food was “organic” by _______.
A. firsthand experience B. the “certified organic” label tag
C. its packaging D. examining its organic certification
2. We can infer that _______.
A. in America, organic food can only be bought in small stores or farmers’ markets
B. organic food is also available in large supermarkets at present
C. organic food is produced by large-scale farms
D. organic food is often beautifully packaged
3. According to the passage, organic food is considered as _______.
A. junk food B. delicious snacks C. green food D. conventional food
4. What is the main idea of the last paragraph?
A. The benefits of organic food. B. The cost of organic food.
C. The disadvantages of organic food. D. Organic food and conventional food.
5. Which of the following statements does NOT support the view that organic farming is more environment-friendly?
A. Organic food is generally thought to be more nutritious.
B. Organic farms are more energy efficient and produce less waste.
C. Organic farms are better than conventional farms at maintaining varieties of plants, insects and animals.

One in five women and one in eight men are becoming more tired and less productive, according to a new Australian study on mobile phone use.
Led by the Queensland University of Technology in Australia, researchers surveyed 709 mobile phone users across the country aged 18 to 83 and asked them a series of questions based on a similar study 13 years ago. Identifying a phenomenon "technoference (科技干扰)", researchers discovered a significant increase in people blaming their devices for losing sleep, becoming less productive and even getting more aches and pains".
According to the study's lead author Dr Oscar, the issue is so bad that 24 percent of women and 15 percent of men are now considered to be " problematic mobile phone users". "When we talk about technoference, we're referring to the everyday intrusions (侵入)and interruptions that people experience due to mobile phones and their usage," he said. "Our survey found technoference had increased among men and women. For example, self-reports relating to the loss of sleep and productivity showed that these negative outcomes had significantly increased during the last 13 years. This finding suggests that mobile phones are potentially increasingly affecting aspects of daytime functioning due to lack of sleep. "
Compared to a 2005 study, "technoference" issues for 18 to 24-year-old experienced a surprising 40. 9 percent rise, while those aged 25 to 29 also recorded a dramatic increase of 23. 5 percent.
Oscar said that with the number of smartphone users around the world expected to surpass 2. 5 billion before the end of this year, the problem of "technoference" could get even worse. "The speed and depth of smartphone take-up makes our population particularly vulnerable to some of the negative consequences of high mobile phone use." he said. "Rapid technological innovations have led to dramatic changes in today's mobile phone technology, which can improve the quality of life for phone users but also result in some negative outcomes. "
1.How are people affected by technoference according to the text?
A.It makes people addicted to communicating online.
B.It pushes people to work at a fast pace.
C.It causes people to sleep less at night.
D.It brings negative outcomes to people of all ages.
2.Which group are most influenced by smartphones?
A.Young women. B.Young man
C.Children. D.Seniors.
3.What does the underlined word "vulnerable" in paragraph 5 probably mean?
A.Widely spread. B.Easily hurt.
C.Deeply devoted D.Absolutely accustomed.
4.What does the text mainly talk about?
A.The increasing side effects of smartphones.
B.Ways to solve technoference problem.
C.Smartphones and people's happiness.
D.The popularity of smartphones.

Food production does great harm to our environment.There are many procedures involved in the manufacture of food that result in greenhouse gases and other pollutants.Some procedures require the consumption of large amounts of fossil fuels,such as the transportation and storage of food products.Other factors that cause great damage to our environment include the overuse of fresh water.
The production of beef is more damaging to the environment than that of any other food we consume,Raising large numbers of cattle requires the production of large amounts of food for the animals.It’s estimated that producing one pound of beef requires seven pounds of feed.
Land use is also a problem.If the cattle are free-range cattle,large areas of land are required for them to live on.This has led to disastrous forest cutting and the loss of rare plants and animal species,particularly in tropical rain forests in Central and South America.
Another problem specific to beef production is methane emissions (甲烷排放).Although many people are aware of the damaging effects of carbon dioxide,they don’t realize methane’s global warming potential is 25 times worse,making it a more dire problem.
Unfortunately,beef consumption is growing rapidly.This is the result of simple supply and demand factors.Specifically,there are two main causes of demand that are encouraging the production of more supply.First,the increase in the world population means there are more people to consume meat.The second factor is socioeconomic advancement.As citizens in developing nations become financially stable,they can afford to buy more meat.
Therefore,one way to reduce the greenhouse gas emissions is for people around the world to significantly cut down on the amount of beef they eat.
1.Which of the following is TRUE?
A. Raising free-range cattle is eco-friendly.
B. People cut down trees for animal habitats.
C. Producing beef can damage the environment.
D. Carbon dioxide causes far more harm than methane.
2.The underlined word “dire” in Para.4 means .
A. urgent B. common
C. typical D. avoidable
3.Beef production is growing rapidly because .
A. more people are in demand of beef
B. developing countries raise more cattle
C. more land is available to raise cattle
D. the cost of raising cattle is relatively low
4.The author writes this article to .
A. describe the booming of the beef production
B. emphasize the advantages of beef production
C. condemn the deforestation of the rain forest
D. argue for a decrease in beef consumption
