【推荐3】The organic (有机的) food market is made up of the sale of organic foods, drinks and related services. These food products do not use a lot of food additives or industrial solvent (溶剂).

Increasing health concerns about the growing number of chemical poisoning cases globally is acting as a driver in the organic food market. People are paying more attention to health because of the harmful effects caused by the presence of chemical pesticides (杀虫剂) in food products.

The chemical pesticides in food products can cause cancer. According to a UN report, around 200,000 people die every year due to bad effects of pesticides in food products. This is causing people to change their focus towards organic food products.

Are organic foods safer? We cannot say yes immediately. Some data show possible health benefits of organic foods. Some studies have shown differences between the organic foods and the traditional ones. But there is little information to prove how these differences can give overall health benefits.

Compared with the traditional foods and drinks, short shelf life of organic foods is controlling the organic food market. For example, a study conducted by a research team shows that the shelf life of organic food products is shorter than traditional products. Similarly, some researchers find that many organic foods have higher levels of bacteria than traditional products, which cause food to go bad. As organic foods don’t have the similar amount of preservative (防腐剂) to that of traditional foods, organic foods are easier to gain bacteria attacks and have a shorter shelf life, which in turn makes it difficult for people to keep them. Thus, people will experience a high risk of buying the bad organic foods.

The organic food market is controlled by authorities such as the US Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA) to ensure high-quality standards of food products. Also, the authorities have come up with strict food labeling rules for the organic food market.

【推荐2】Brazil sports are out of control! Brazil may be one of the most sports­crazy countries in the world. Whether you are into watching or playing, Brazil sports have a lot to offer everyone.

Football in Brazil is more than a sport. It's a way of life. Football is popular in Brazil for several reasons. One reason is that it is fast paced and fun to watch. This is the reason why the World Cup Soccer is the most watched sports event in the world aside from the Summer Olympics. Also, you don't need anything to play soccer except for something to kick, and a big area in which to play. Few will argue if you say that Brazil leads the world in football. No nation has won as many world cups as Brazil.

Volleyball is a close second in Brazil sports. In the world of international volleyball, Brazil wins many championships of all kinds, including indoor and beach volleyball. Brazil has nearly 5,000 miles of coastline. If you go to a beach in Brazil, there will always be a volleyball game going on somewhere, and usually two or three.

Footvolley was created in Brazil in the 1960s. It is a mix of football and volleyball, where the players must use their feet and head to get the ball over the net and into the opponents' court, and is also played in sand. It is one of the most popular beach sports in Brazil.

Swimming, tennis, rugby, boxing, judo, sailing, golf, surfing, and handball are all greatly popular in Brazil.

【推荐3】Mushrooms on a log may each seem like quiet, separate organisms, but they are actually the above-ground fruit belonging to a fungus (真菌)，connected to the large organism by a root network called mycelium (菌丝). Although mushrooms may not seem very talkative either, a new study shows electrical signals travelling through their mycelium network could help the organism communicate.

According to the research, some mushrooms can use electrical impulse (脉冲) to share and process information in their body. When signal activity increases, it creates complicated patterns that may function like words in human speech.

Previous research has found that mushrooms can send electrical signals underground through long, thread-like structures, which expand to form a network of mycelium. It works like nerve cells that send signals to other parts of the human body. Some studies have shown that electrical activity will increase when the mycelium of wood-digesting mushrooms touches blocks, which may indicate that mushrooms can use these impulses to share information about food or injury.

In the new study, four species were analyzed. Researchers listened to the mushrooms’ chat using tiny electrodes (电极) connected to mycelium to measure the power in signal activity. Each result in the activity was organized into several groups and given a linguistic (语言的) and information complexity analysis. The power varied in duration and length, with some lasting up to 21 hours. The electrical points resembled a human vocabulary of up to 50 words. However, only 15 to 20 mushrooms’ words are used frequently.

Mushrooms’ words are also similar in length to human words. The mushroom’s word length averaged over the four species is 5.97, which is of the same range as an average word length in some human languages. For instance, it is 4.8 in English and 6 in Russian.

While the research shows mushrooms can produce patterns of electrical signals, there’s no way to tell what they are talking about, if they are at all. Though comparing the mushroom’s electrical signals to human speech is interesting and notable, some researchers are doubtful. “Though interesting, the interpretation as language seems somewhat overenthusiastic and requires more research,” says Dan Bebber from the University of Exeter.
