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 drunk 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 lots of Ooho bubbles 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 ‎ 22‎ 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 for a patent for their new advancement. 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 when the production machine is running. It is quickly making a rise, so keep an eye out this year for these bottles of the future.‎ ‎【解题导语】　本文是一篇说明文。由于塑料瓶的使用不但浪费金钱，还会造成环境污染，Skipping Rocks Lab发明了一种可以食用的包装材料Ooho。本文介绍了Ooho的食用方法，运输方法以及制作成本，并展望了其市场前景。‎ ‎4．How is most plastic dealt with in America?‎ A．It’s sold. B．It’s recycled.‎ C．It’s buried. D．It’s wasted.‎ D　解析：细节理解题。根据第一段中的“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.”可知，在美国只有23%的塑料最终回到回收站，这意味着价值超过10亿美元的塑料被视为垃圾。据此可知，在美国，大部分塑料被当成垃圾处理了，故D项正确。‎ ‎5．Why did the team invent Ooho?‎ A．To make a profit for a company.‎ B．To protect the environment.‎ C．To make people eat as they drink.‎ D．To reduce the cost of the plastic bottle.‎ B　解析：细节理解题。根据第二段中的“And too much plastic is sure to do harm to the environment, which could account for their purpose of such a new invention.”可知，由于塑料瓶的使用污染了环境，故Skipping Rocks Lab发明了一种可以食用的包装材料Ooho，故B项正确。‎ ‎6．What can we infer about Ooho from the text?‎ 22‎ 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.‎ C　解析：推理判断题。根据第三段中的“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.”可知，该产品的制造成本比塑料瓶低。据此可推知，该产品的售价也可能比塑料瓶低，故C项正确。‎ ‎7．What 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.‎ A　解析：推理判断题。根据最后一段中的“Ooho is catching many people’s attention and has raised over $1 million and gained 1，000 investors in only three days.”可知，Ooho吸引了很多人的注意，在三天时间内就得到了1 000 位投资者的关注，筹集到100多万美元；再结合文章最后一句“It is quickly making a rise, so keep an eye out this year for these bottles of the future.”可推知，作者最后一段想要表达的是，在未来Ooho一定能获得成功，故A项正确。‎ ‎【难句分析】　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.‎ 分析：本句是一个主从复合句。句中“where tons of plastic bottles are used, and frequently left behind as litter”为where引导的非限制性定语从句，修饰先行词“outdoor events”，where在从句中作地点状语。‎ 译文：该产品是针对诸如马拉松、音乐节和体育赛事等大型户外活动而发明的，在这些活动中，会使用数吨塑料瓶，并且这些塑料瓶经常被当作垃圾扔下。‎ Ⅱ.完形填空 ‎(2020·太原高三模拟)When I was a freshman in college, I had some seniors telling me, “You should not really try to get the highest grades.
