Question

In an effort to discourage people from using plastics，scientists have been hard at work inventing alternative packaging products．From water bottles made from seaweed to cutlery(餐具) made from rice and wheat，a number of inventions are set to change the way we eat while we are on the go，or having a relaxing picnic in the park．

The idea of using seaweed to make eco-friendly(环保的) 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 get experimenting and create your own recipes?

1.Why do scientists invent alternative packaging products?

A. To make people’s life more convenient．

B. To reduce the amount of plastic waste．

C. To charge the way we picnic outside．

D. To show off their inventive talents．

2.What makes Ari 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 breakdown plastic waste．

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

【解析】本文讲述了为了减少塑料废品，科学家一直努力发明各种替代的包装产品，现在更有人发明了可吃的瓶子和汤匙，未来人们可能会在家里制造可食用的餐具。

1.B细节理解题。根据第一段第一句In an effort to discourage people from using plastics，scientists have been hard at work inventing alternative packaging products．可知，科学家发明替代塑料的包装产品是阻止人们使用塑料，也就是为了减少塑料废品。故选B。

2.D细节理解题。根据第二段第三句As soon as these bottles are empty they will begin to break down，though they would be perfectly safe to eat．可知，Ari Jonsson的水瓶空的时候会自动分解，所以他的水瓶是环保的。故选D。

3.B细节理解题。根据第二段第三句后半句As soon as these bottles are empty they will begin to break down，though they would be perfectly safe to eat．再根据第三段中After the success of his spoons, Mr Pessapaty is ready to expand and introduce forks and chopsticks to his menu.可知，Ari发明的瓶子和Mr Pessapaty发明的汤匙的共同点是可以安全地吃。故选B。

4.A推理判断题。根据最后一段第二句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．可知，更好的是，类似可食用的餐具可以在家里制造，可能对于孩子来说是一个科学项目或仅仅是和朋友们一起玩，故A项“家庭制造的可食用餐具很可能会流行”正确。
