The idea of light pollution has developed with the increase of lights in cities. In many areas, this light makes it difficult or impossible to observe stars and planets in the night sky.
There are a number of reasons why light pollution is important. One has become clear at the Mount Wilson Observatory near Los Angeles, California. Today, light from Los Angeles makes the night sky above Mount Wilson very bright. It is no longer an important reasearch center because of light pollution.
Light pollution threatens to reduce the scientific value of research telescoples in other important observatories. They include Lick Observatory near San Jose, California and Yerkes Observatory near Chicago, Illionis.
Light pollution is the result of wasted energy. Bright light that shines into the sky is not being used to provide light where it is needed on Earth. Poorly designed lighting causes a great deal of light pollution. Lights that are brighter than necessary also cause light pollution.
Most people in America are surprised to find out that they are able to see our own galaxy(星系),the Milky Way, with their own eyes. But about threefourths of Americans cannot see the Miky Way because of manmade light.
Objects in the night sky are resources that provide everyone with wonder. But light pollution threatens to prevent those wonderful sights from being seen.
1.Light pollution usually occurs________.
A.in cities B.in the country
C.in wild areas D.in developing countries
2.Which of the following is TRUE according to the passage?
A.Mount Wilson Observatory is the most important one in America.
B.Light pollution affects observatories only.
C.In the dark night people can observe the sky clearly.
D.Astronomers can observe the stars clearly by the lights of the cities.
3.The victims affected by the light pollution are________.
A.children B.grownups C.students D.observatories

高二英语单项填空简单题查看答案及解析
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.
1.How is most plastic dealt with in America?
A.It’s sold. B.It’s recycled.
C.It’s buried. D.It’s wasted.
2.Why 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.
3.What 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.
4.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.
