The global movement to get rid of plastic has led to concern about single-use plastic tea bags, with many people now considering them wasteful and potentially dangerous. New research by a team at McGill University found that a tea bag soaked (浸泡) in 95℃ water released 11.6 billion units of microplastics and 3.1 billion smaller nanoplastic particles (微粒). The researchers are suggesting that dipping into boiling water makes the tea bags release higher numbers of plastic particles or poisonous substances.

This quantity of microplastics is larger than the amount consumed by a person in an entire year, so the question remains whether the consumption of microplastics is harmful to the human body. Worryingly, when exposed to these levels of microplastics, water fleas (水蚤) were noted to show body and behavior abnormalities. For a nation that consumes up to 60.2 billion cups of tea a year, this has caused concern. While there is no evidence that these micro-plastics affect human health, the UN has said more research is needed to fully understand the effect microplastics have on the body.

It is not only plastic tea bags that contain chemicals. 96 per cent of paper tea bags sold in the UK contain polypropylene—a chemical used to close the openings. This chemical can makeup 25 per cent of the bag.

Some brands such as the Co-op and PG Tips had already adopted 100 per cent compostable (可堆肥的) ten bags due to public pressure. While Lidl is exploring the alternative for biological tea bags. Yorkshire Tea is aiming to switch to plant-based materials by the end of the year. The most eco-friendly tea, however, remains loose leaf in a pot or cup.

【推荐1】Parents whose children think the latest Nike or Adidas shoes may be better than buying old-fashioned plimsolls (橡胶底帆布鞋) because they encourage a healthier style of running, researchers said.
Big companies, like Nike and Adidas, make millions of dollars from selling highly-cushioned shoes(厚增高的运动鞋) both as fashion and sports shoes. The researchers warn that wearing such shoes from an early age can make it difficult to run in a healthy way. Once we have grown used to running in this kind of shoes, it is very difficult to change our technique, even if we remove our shoes, it can raise the risk of injury.
Children should be encouraged to wear shoes with thin soles such as plimsolls from a young age to help them develop a natural “barefoot” running style, experts said.
Dr Mick Wilknson, who did the research, told the British Science Festival in Newcastle, “If I would advise someone on what to give their child, I would say don’t go and buy them expensive Adidas or Nike, just get them a pair of flexible, flat shoes. Give them basic foot-ware, nothing fancy, nothing particularly cushioned.”
Running in flat shoes, barefoot, encourages the runner to use the front of their foot which is a better technique for running, especially long distances as the human was designed to do.
Around the world, and in particular in the US, running barefoot is becoming more and more popular with many long distance runners training without shoes.
Dr Mick Wilknson believes that training and running barefoot or in flat running shoes can help reduce injuries to runners, he said: “Injury rates in running have not changed since the 1970s, despite claims of improvements in running shoes. That has led some to conclude that barefoot running is better.”
1. What does the second paragraph mainly tell us?
A.Nike and Adidas are producing low-quality trainers.
B.It is improper to wear hi-tech Trainers at an early age.
C.It is unnecessary to buy hi-tech Trainers at an early age.
D.Hi-tech Trainers are too expensive for ordinary people to afford.
2. Why are people advised to wear plimsolls?
A.They have a new fashion
B.They have better quality.
C.They are healthier
D.They are cheaper.
3. What can we infer according to Dr Mick Wilknson?
A.Shoes industry is gradually declining(下降).
B.Barefoot running is more popular with people.
C.Plain plimsolls will be replaced by barefoot running.
D.People mustn’t run without shoes for a long distance.
4. Who is the passage written mainly for?
A.The boss of shoes shop
B.The runner of long distance
C.The boss of producing shoes
D.The parents of young children
