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 t0 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?

A. To make people's life more convenient.

D. To reduce the amount of plastic waste.

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

B. They are cheap to produce and buy.

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.

Ask any American what he/she is doing on Sunday, February 7 and the answer is likely to be either hosting or attending a Super Bowl Party. Played for the title of the National Football League Champion, Super Bowl is the most watched annual television program in the United States.

That's because Super Bowl which is celebrating its Golden Anniversary this year, is more than just a 60-minute football game—it is a well-designed production that features half-time performances, fireworks shows and television ads that people discuss for days.

But most important of all, it is the day to set aside all diets and enjoy foods one would normally avoid or at least not consume at the same time. It should, therefore, come as no surprise that Super Bowl Sunday is one of the biggest food consumption days in the U.S. — Second only to Thanksgiving.

The noshing will start early in the day, long before matches begin and continue long after the 2016 NFL Champions have retired to celebrate.

As a result, it is estimated that on Sunday, the nation will consume 1.2 million pounds of potato chips, 8.2 million pounds of tortilla chips, 3.8 million pounds of popcorn and 3 million pounds of nuts.

When the real hunger pains start to hit, they will seek out comfort foods. Not surprisingly, pizza tops the list. Chicken wings are also very popular. It is estimated that almost 1.3 billion wings will be consumed on Super Bowl Sunday. Other favorites include bacon, hot dogs and burgers.

But the food consumption is not without consequences. Data released indicates that antacid (解酸藥) sales increase by 20% on the Monday following the big game. Additionally, over seven million Americans call in sick. It is no wonder that fans have been urging the government to declare Super Bowl Monday a holiday.

1.Why does Super Bowl become the most popular television program?

A. It is the longest football game.

B. It is hosted by famous film stars.

C. It contains the most wonderful ads.

D. It involves in various performances.

2.Which can replace the underlined word “noshing” in Paragraph 4?

A. playing B. eating

C. competing D. resting

3.Which comfort food is consumed the most？

A. Hot dogs. B. Pizza.

C. Nuts. D. Chicken wings.

4.What bad result might Super Bowl Sunday lead to?

A. Lots of food is wasted.

B. Public disorder is caused.

C. Some people have an upset stomach.

D. Many people lose their work.
