1 . An American company has developed a new technique (技术) to make bread stay fresh for 60 days.

Scientists found that a kind of mould (霉菌) caused bread to go bad. The new technique kills the mould and keeps the food for longer time. This means there will be less waste of food in the world in future.

Food waste is a big problem in most developed countries. In the US, an average (普通的) family throws away 40% of the food they buy, which adds up to $165bn every year, about 330 million tons in weight. Bread takes a larger part. In the UK, 32% of the bread they buy is thrown away as waste when they can still be eaten.

The bread usually goes mouldy (发的) in around 10 days, but the American company says the new technique will keep the bread free from mould for two months.

”We treated a piece of bread in a special machine. At 60 days it had the same amount of mould as it was first made,“ says Mr. Stull, the leader of the company.

Although there are a lot of bread makers interested in the new technique, few customers like the idea. They say they don’t think a piece of bread which lasts for 60 days tastes good.

”We’ll have to make our customers accept the idea. But it will take some time,“ says Mr. Stull.

10 . Plastic straws (吸管) have been a major problem in global discussions of environmental damage. Maybe because of their small size, the production cost of straws is low. In many countries, straws are offered freely after buying soft drinks. Therefore, plastic straws are one of the most used plastics and pollutants in the world.

The plastic straw is light and small. Due to their small size, plastic straws are often eaten by sea animals. Environmentalists have shown that the death of many sea animals is caused by eating plastic straws. The other damaging characteristic of plastic straws is that they are made of materials which cannot degrade. That means the materials cannot be changed into small harmless (无害的) ones.

The most effective way of dealing with the environmental pollution caused by plastic straws is the reuse or banning (禁止) the use of plastic straws. Being plastics, the straws can be made new items. Many organizations around the world change used straws into new products. In Africa, local communities collect used plastic straws and use them to make mats and bags. Another way of dealing with environmental pollution caused by plastic straws is placing a ban on their production and use. Experts advise governments to ban using plastic straws to save the environment. A few countries in the world such as Rwanda, Macedonia, China, Kenya have already banned the use of plastic bags and are expected to include plastic straws and bottles. But it will be a long way to do this effectively.

There are few environmentally friendly and biodegradable productions to take the place of plastic straws. These productions include paper straws, bamboo straws. However, such straws are usually expensive as their production cost is high. It’s still a question whether they can entirely take the place of plastic straws.
