Air pollution is caused by the following _________: about half of the problem is caused by vehicles.

高三英语完成句子中等难度题查看答案及解析

While fossil fuels — coal, oil, gas — still produce roughly 85 percent of the world’s energy supply, it’s clearer than ever that the future belongs to renewable sources such as wind and solar. The move to renewables is picking up the development around the world: They now account for more than half of new power sources going in operation.

Some growth stems from a commitment by governments and farsighted businesses to fund cleaner energy sources. But increasingly the story is about the falling prices of renewables, especially wind and solar. The cost of solar panels has dropped by 80 percent and the cost of wind turbines（涡轮机）by close to one-third in the past eight years.

In many parts of the world renewable energy is already an important energy source. In Scotland, for example, wind turbines provide enough electricity to power 95 percent of homes. While the rest of the world takes the lead, especially China and Europe, the United States is also seeing an amazing shift. In March, for the first time, wind and solar power accounted for more than 10 percent of the power generated in the US, reported the US Energy Information Administration.

President Trump has underlined fossil fuels — especially coal — as the path to economic growth. In a recent speech in Iowa, he dismissed wind power as an unreliable energy source. But that message did not play well with many in Iowa, where wind turbines dot the fields and provide 36 percent of the state’s electricity generation — and where tech enterprise like Microsoft are being attracted by the availability of clean energy to power their data centers.

The question “what happens when the wind doesn’t blow or the sun doesn’t shine?” has provided a quick remark for skeptics. But an increase in the storage capacity of batteries is making their ability to keep power flowing around the clock more likely.

The advance is driven in part by vehicle manufacturers, who are placing big bets on battery-powered electric vehicles. Although electric cars are still uncommon on roads now, this massive investment could change the picture rapidly in coming years.

While there’s a long way to go, the trend lines for renewables are zooming. The pace of change in energy sources appears to be speeding up — perhaps just in time to have a meaningful effect in slowing climate change. What Washington does — or doesn’t do — to promote alternative energy may mean less and less at a time of a global shift in thought.

1.According to Paragraph 3, the use of renewable energy in America ______.

A.has proved to be impractical B.is as common as in Europe

C.faces many challenges D.is progressing greatly

2.It can be learned that in Iowa ______.

A.wind is a widely used energy source

B.wind energy has replaced fossil fuels

C.there is a shortage of clean energy supply

D.tech enterprises are investing in clean energy

3.Which of the following is true about clean energy according to Paragraphs 5&6?

A.Its application has increased battery storage.

B.Its continuous supply is becoming a reality.

C.It is commonly used in car manufacturing.

D.Its sustainable exploitation will remain difficult.

4.It can be inferred from the last paragraph that renewable energy ______.

A.will bring the US closer to other countries

B.will accelerate global environmental change

C.is not really encouraged by the US government

D.is not competitive enough with regard to its cost

Some scientists say that animals in the oceans are increasingly threatened by noise pollution caused by human beings.

The noise that affects sea creatures comes from a number of human activities. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines. Such noises are added to natural sounds. These sounds include the breaking of ice fields, underwater earthquakes, and sounds made by animals themselves.

Decibels (分贝) measured in water are different from those measured on land. A noise of one hundred and twenty decibels on land causes pain to human ears. In water, a decibel level of one hundred and ninety－five would have the same effect.

Some scientists have suggested setting a noise limit of one hundred and twenty decibels in the oceans. They have observed that noises at that level can frighten and confuse whales(鲸鱼).

A team of American and Canadian scientists discovered that louder noises can seriously injure some animals.

The research team found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales' ability to exchange information and find their way. Some of the whales even died. The explosions had caused their ears to bleed and become infected.

Many researchers whose work depends on ocean sounds are against a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research.

Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists don't think that noise is a greater danger than they believed. They want to prevent noises from harming creatures in the ocean.

1.According to the passage, natural sounds include all of the following EXCEPT________.

A．sounds made by animals themselves

B．ocean drilling

C．underwater earthquakes

D．the breaking of ice fields

2.Which of the following is true of whales？

A．They won't be confused by noises.

B．They are deaf to noises.

C．Their ability to reproduce will be lowered by high­level noises.

D．Their hearing will be damaged by high­level noises.

3.According to the passage, what will scientists most probably do in the future?

A．They will work hard to reduce ocean noise pollution.

B．They will protect sea animals from harmful noises.

C．They will try to set a limit of 120 decibels.

D．They will study the effect of ocean noise pollution.
