Morocco has a lot of sun, a lot of deserts and a high demand for imported fuel. And that's why the Moroccan government is moving ahead with a huge concentrated solar power plant near the desert city of Ouarzazate — one of four plants in total which, when completed, will have generating capacity(發(fā)電量) of 580MW. Combined with the country’s wind and hydro-power (水力發(fā)電) efforts, Morocco’s ambitious solar push will mean the country will get close to 50% of its electricity from renewable generation as early as 2020.

Phase I of the project, the 160MW Noor l, is going to start generating electricity next month and includes a capacity for molten sand energy storage which will allow up to 3 hours of electricity generation after the sun goes down. Phases 2 and 3 will have the capacity for up to eight hours of storage, meaning that solar energy really could be used to power homes around the clock.

Besides the scale of such plans, what’s impressive to me is how quickly the renewable energy can be developed. What other forms of energy could so greatly change a country’s energy composition in just a few short years? Not only should this be an encouraging sign for those of us who favor renewable energy, but it also should give reason for would-be investors in traditional fossil fuel generating industry.

If renewable energy costs continue to fall, even existing(現(xiàn)有的) coal and gas plants will find themselves limited by newer, cleaner forms of energy that can be increased rapidly.

Interestingly, some analysts suggest this is happening already. In the US, for example, coal power plants are being retired earlier than expected due to a combination of increased competition from gas and renewable energy, as well as tighter regulations of emissions (排放). Also, increasing amounts of solar and wind cause gas and coal plants not to use, significantly reducing their profits and further giving an edge to the clean energy competition.

If this proves to be the case in North Africa too, Morocco's solar ambitions could help transform the energy system well beyond its own borders.

1.What's the main theme of the passage?

A. Solar energy is fully developed in Morocco.

B. There are advantages of developing solar energy.

C. Morocco is a country with quantities of deserts.

D. Morocco's efforts to generate renewable electricity.

2.What is the advantage of Phase l?

A. Its energy storage can last up to three hours.

B. It has the capacity for as many as eight hours.

C. It continues producing electricity after the sun sets.

D. It is going to begin generating electricity in a month.

3.What does the author think of the renewable energy development?

A. Upset. B. Striking. C. Sensitive. D. Doubtful.

4.Coal power plants in the US are being retired earlier than expected because of ________.

A. various reasons B. heavy pollution

C. fierce competition D. the government's limitation

Last night a strong wind as well as heavily rain struck our area. News came that the trees in the park two kilometers away from our school was blown down. This afternoon, we set off the park to do some cleaning. The head of the park met us or gave us some advice on how to clear away the falling trees, branches and leaves. Some times later, we were working hard when it begins to rain. Because few of us had taken along umbrellas or raincoats, so we were all wet. A rain lasted about an hour and it was a pity that they had to stop our work.

A（2016·新課標(biāo)全國卷Ⅰ）

You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

Jane Addams(1860-1935)

Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community(社區(qū)) by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.

Rachel Carson(1907-1964)

If it weren’t for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world’s lakes and oceans.

Sandra Day O’Connor(1930-present)

When Sandra Day O’Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator(參議員) and, in 1981, the first woman to join the U.S. Supreme Court. O’Connor gave the deciding vote in many important cases during her 24 years on the top court.

Rosa Parks(1913-2005)

On December 1, 1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. It lasted for more than a year, and kicked off the civil-rights movement. "The only tired I was, was tired of giving in," said Parks.

1. What is Jane Addams noted for in history?

A. Her social work.

B. Her teaching skills.

C. Her efforts to win a prize.

D. Her community background.

2. What was the reason for O’Connor’s being rejected by the law firm?

A. Her lack of proper training in law.

B. Her little work experience in court.

C. The discrimination against women.

D. The poor financial conditions.

3. Who made a great contribution to the civil-rights movement in the U.S.?

A. Jane Addams. B. Rachel Carson.

C. Sandra Day O’Connor. D. Rosa Parks.

4.What can we infer about the women mentioned in the text?

A. They are highly educated. B. They are truly creative.

C. They are pioneers. D. They are peace-lovers.

科目：高中英語 來源：遼寧省沈陽市2016-2017學(xué)年高一下學(xué)期期末聯(lián)考英語試卷 題型：閱讀理解

Four days after Dad’s 67th birthday, he had a heart attack. Luckily, he survived. But something inside him had died. His enthusiasm for life was gone. He refused to follow doctor’s orders, and his sour attitude made everyone upset when they visit him. Dad was left alone.

So I asked Dad to come to live with me on my small farm, hoping the fresh air would help him adjust. Within a week after he moved in, I regretted the invitation. He criticized everything I did. I became frustrated. Something had to be done.

One day I read an article which said when given dogs, depressed patients would be better off. So I drove to the animal shelter that afternoon. As soon as I got there, a pointer’s eyes caught my attention. They watched me calmly.

A staff member said: “He got here two weeks ago and we’ve heard nothing. His time is up tomorrow.”

I turned to the man in horror. “You mean you’re going to kill him?”

“Ma’am,” he said gently. “We don’t have room for every unclaimed dog.”

The staff member’s calm brown eyes awaited my decision. “I’ll take him,” I said.

I drove home with the dog on the front seat beside me. I was helping it out of the car when Dad walked onto the front porch. “Look what I got you!” I said excitedly.

Dad wrinkled his face. “I don’t want it,” he muttered, turning back towards the house. Then, suddenly, the dog pulled free from my grasp. He sat down in front of my Dad.

Dad’s anger melted, and soon he was hugging the dog.

This was the beginning of a warm friendship. Dad named the dog Cheyenne. Together they spent long hours walking down dusty lanes and relaxing on the banks of streams.

Dad’s bitterness faded, and he and Cheyenne went on to make many friends. Then, late one night two years later, I felt Cheyenne’s cold nose burrowing(搜尋) through my bed covers. He had never before come into my bedroom at night. I ran into my father’s room and found that he had passed away.

Two days later, my shock and grief deepened when I discovered Cheyenne lying dead beside Dad’s bed. As I buried him near their favorite stream, I silently thanked the dog for restoring Dad’s peace of mind.

1.After the author’s father survived the heart attack, he .

A. no longer wanted to live

B. was left alone to get full rest

C. ignored everyone who visited him

D. became unpleasant toward other people

2.Why did the author take the pointer home?

A. It was a type that is known for its friendliness

B. Its eyes made her think it was the best dog available

C. It caught her attention right away and she didn’t want it to be killed

D. It was good at getting people’s attention and entertaining them

3.From the last two paragraphs we can conclude that .

A. more attention should be given to old people

B. dogs are so loyal that they usually die for their friends

C. the author’s father and Cheyenne formed a real connection

D. friendship and care is much more efficient than the medicine

4.Which section of a newspaper is the source of the passage?

A. Health B. Entertainment

C. Education D. Friends
