【题目】Not only does the use of plastic water bottles hurt your wallet, it also increases pollution and wastes energy and water. Only 23% of all plastic in America ends up in a recycling bin, meaning over $ 1 billion worth of plastic is treated as rubbish a year. Recently, Skipping Rocks Lab has invented a kind of water bottle called Ooho.

It is a convenient, clear water bottle that can either be drunken or eaten. To drink it, you can either peel off the membrane(薄膜) or tear a hole in the membrane with your teeth to pour the water into your mouth. To eat it, you simply put the whole bottle in your mouth. One problem the scientists have run into is how to ship large amounts of Ooho bubbles(水泡) without arriving with a very wet truck. However, they have attempted to package units of individual bubbles together inside a larger and thicker membrane. It is targeting large outdoor events, such as marathons, music festivals, and sporting events, where tons of plastic bottles are used, and frequently left behind as litter. And too much plastic is sure to do harm to the environment, which could account for their purpose of such a new invention.

The team has been working for the past two years to develop the technology and materials needed to produce Ooho; they have recently applied a patent for their new advancements. The price for an individual bubble or a unit of bubbles has not been set yet, but they cost about two cents to create a unit, which is cheaper than plastic bottles. It has appeared at events in London, San Francisco, Boston, at conferences, festivals, and so on.

Ooho is catching many people’s attention and has raised over $ 1 million and gained 1,000 investors in only three days. It is mostly being sold at events at the moment to keep the consumer’s interest while the production machine is getting up and running. It is quickly making a rise,so keep an eye out this year for these bottles of the future.

1How is most plastic dealt with in America?

A. It’s sold. B. It’s recycled.

C. It’s buried. D. It’s wasted.

2Why did the team invent Ooho?

A. To make a profit for a company. B. To protect the environtnent.

C. To make people eat as they drink. D. To reduce the cost of plastic bottle.

3What can we infer about Ooho from the text?

A. It is easy and safe to ship it in large amounts.

B. It has become popular since it began to be sold.

C. It might be sold at a lower price than plastic bottles.

D. It cost the team a lot of money to develop the technology.

4What does the author really want to say in the last paragraph?

A. Ooho is to be a success in the future.

B. Ooho is being supported by smart people.

C. Ooho is taking the place of plastic bottles now.

D. Ooho is being produced to attract more investors.

【题目】A Teenage Inventor

The world could be one step closer to quick and inexpensive Ebola detection thanks to a teenager from Connecticut.

Olivia Hallisey, a junior at Greenwich High School, was awarded $50,000 in the Google Science Fair for her new method that detects Ebola, a virus that causes bleeding from different parts of the body and usually causes death. Olivia’s method is to ask patients to put their saliva (唾液) onto a testing card. The card changes color if the person is catching Ebloa. Present Ebloa tests take up to 12 hours and cost $1,000. Olivia’s method, however, can be done just in 30 minutes for about $25. Besides, the sample (样本) doesn’t have to be put in a refrigerator thanks to the silk material Olivia uses to produce the testing cards.

Olivia was inspired to deal with this global problem after watching the news that more than 10,000 people died from Ebola in West Africa. She was particularly worried about the fact that, while the acts of involvement can improve survival rates, present detection methods are costly, time-consuming and require complex tools. Olivia got help from her science research teacher. She drew out directions from past research, and figured out detection systems that have proven to work with other diseases, including Lyme disease and yellow fever.

“What affects one country affects everyone,” Olivia told CNBC. “We have to work together to find answers to the huge challenges which cause harm to the global health.” The Connecticut’s teen, who hopes to become a doctor one day, was named the Google Science Fair winner in the competition of 20 competitors from across the globe. The fair is open to young people between the ages of 13 and 18 in most countries.

Olivia hopes her success will inspire other girls interested in science and computers. “I would just encourage girls to try it in the beginning, and remind them that they don’t have to feel naturally drawn or feel like they have a special talent for maths or science,” she told CNBC, “but just really look at something they are interested in and then think how to improve something or make it more enjoyable or relate it to their interests.”

1According to the passage, present Ebola detection methods ______.

A. must use a large amount of samples

B. may detect other deadly viruses as well

C. have proven to be ineffective in practice

D. require samples to be kept in refrigerators

2What can we learn about Olivia’s method?

A. Time-consuming. B. Cheap.

C. Complex. D. Out-of-date.

3What does the underlined word “drawn” in Paragraph 5 probably mean?

A. Attracted. B. Controlled.

C. Admitted. D. Exposed.

4The Google Science Fair is intended for ______.

A. students B. doctors

C. inventors D. scientists
