In an effort to discourage people from using plastics, scientists have been hard at work inventing alternative packaging products.

The idea of using seaweed(海草) to make eco-friendly water bottles has been around for a few years. Recently, Ari Jonsson took his invention—a water bottle made from red seaweed—to show off at a festival. The bottles will only hold their shape as long as they are filled. As soon as these bottles are empty they will begin to break down, though they would be perfectly safe to eat. Ari Jonsson's bottles are a step closer to a widely used alternative to the current plastic ones.

The eatable water container is not the only product to add to our image of the future. Narayana Pessapaty has also created eatable spoons. After the success of his spoons, Mr. Pessapaty is ready to expand and introduce forks and chopsticks to his menu. His aim is to largely reduce the amount of plastic waste, which is a huge problem for waste sites all over the world. It is a product that may take up to 500 years to break down, and recycling companies worldwide are struggling to deal with it.

Aside from the obvious benefits to the environment, this new packaging is also cheap to produce and therefore cheap to buy. Even better is the fact that similar eatable cutlery can be made at home, possibly a science project for children or just fun with friends. Why not experiment and create your own recipes?

1.Why do scientists invent alternative packaging products?

A. To make people's life more convenient.

B. To show off their inventive talents.

C. To change the way we picnic outside.

D. To reduce the amount of plastic waste.

2.What makes Art Jonsson's water bottles eco-friendly?

A. They can be made at home.

B. They are cheap to produce and buy.

C. They will hold their shape when they are filled.

D. They will break down themselves when empty.

3.What do Ari and Narayana's inventions have in common?

A. They are convenient to carry.

B. They are safe to eat.

C. They can be used for a short time.

D. They are heavier than plastics.

4.What can be inferred from this passage?

A. Home-made eatable cutlery is likely to be popular.

B. Eatable cutlery will completely replace plastics in the near future.

C. No recycling companies can break down plastic waste.

D. It's unsafe for individuals to invent eatable cutlery at home.

Hummingbirds(蜂鸟) are one of nature’s most energetic fliers and the only birds to hover(盘旋) in the air by relying on their strength alone.

Now scientists have found that it is the ratio(比值) of the bird’s wing length to its width that makes them so efficient. The discovery is helping experts compete with 42 million years of natural selection to build helicopters that are increasingly efficient.

David Lentink, an assistant professor at Stanford University in California, tested wings from 12 different species of hummingbirds, which he sourced from museums. He placed them on a machine used to test the aerodynamics(气力学) of the helicopter blades(桨叶). Professor Lentink’s team used the same machine to test the blades from an advanced micro-helicopter used by the UK’s army. They found that the micro-helicopter’s blades are as efficient at hovering as the average hummingbirds.

But while the micro-helicopter’s blades kept pace with the average hummingbird wings, they could not keep up with the most efficient hummingbird’s wing. The wings of Anna’s hummingbird were found to be about 27 percent more efficient than the man-made micro- helicopter’s blades.

While Professor Lentink wasn’t surprised at nature’s superiority, he said that helicopter blades have come a long way. “The technology is at the level of an average hummingbird,” he said. “A helicopter is really the most efficient hovering device that we can build. The best hummingbirds are still better, but I think it’s amazing that we’re getting closer. It’s not easy to match their performance, but if we build better wings with better shapes, we might match hummingbirds.”

Professor Lentink said that we don’t know how hummingbirds maintain their flight in a strong wind, how they navigate(确定方向) through branches, or how they change direction so quickly. He thinks that great steps could be made by studying wing aspect ratios-the ratio of wing length to wing width. Understanding these abilities and characteristics could be a benefit for robotics and will be the focus of future experiments.
