（届河北省衡水中学高三第一次模拟考试英语试卷）
What will power your house in the future？Nuclear，wind，or solar power？According to scientists at the Massachusetts Institute of Technology (MIT) in the US，it might be leaves — but artificial (人造的) ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用)．Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts (催化剂)．Similar to natural leaves，it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell，which uses those two materials to produce electricity，located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card，scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Nocera at a conference of the American Chemical Society.
The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf，by contrast，is made of cheap materials，easy to use and highly stable. In laboratory studies，Nocera showed that an artificial leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful，new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now，the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides，the device can run in whatever water is available；that is，it doesn't need pure water. This is important for some countries that don't have access to pure water.
With the goal to “make each home its own power station” and “give energy to the poor”，scientists believe that the new technology could be widely used in developing countries，especially in India and rural China.
Which of the following orders correctly shows how the artificial leaf is used to produce electricity?
a．artificial leaves split water into hydrogen and oxygen
b．the hydrogen and oxygen gases are stored in a fuel cell
c．the artificial leaves are put in water
d．the fuel cell uses hydrogen and oxygen to produce electricity

A．c，a，b，d	B．c，b，a，d
C．b，c，a，d	D．c，a，d，b

The purpose of the scientists at MIT in developing the new artificial leaf is to________.

A．build up more power stations in the world

B．provide cheaper energy for developing countries

C．offer people in developing countries access to pure water

D．gain a deeper understanding of the photosynthesis process

The main idea of this passage is ________.

A．an introduction to the history of artificial leaves

B．a mixture of water power and solar energy

C．giving energy to the poor

D．an invention copying photosynthesis

“The first and best of victories for a man is to conquer himself; to be conquered by himself is, of all things, the most shameful,” says Plato. Self-control is at the root of all the advantages. Let a man give in to his impulses (冲动) and feelings, and from that moment he gives up his moral freedom.
A single angry word has lost many friends. When Socrates found in himself any temper or anger, he would check it by speaking low in order to control himself. If you are conscious of being angry, keep your mouth shut so that you can hold back rising anger. Many a person has dropped dead in great anger. Fits of anger bring fits of disease. “Whoever the gods would destroy they first make them mad.” “Keep cool,” says Webster, “anger is not argument.” “Be calm in arguing,” says George Herbert, “for fierceness (狂怒) makes error a fault.”
To be angry with a weak man is to prove that you are not strong yourself. “Anger,” says Pythagoras, “begins with foolishness and ends with regret.” You must measure the strength of a man by the power of the feelings he conquers, not by the power of those which conquer him.
Self-control is man’s last and greatest victory.
If a man lacks self-control he seems to lack everything. Without it he can have no patience, no power to govern himself; he can have no self-confidence, for he will always be controlled by his strongest feeling. If he lacks self-control, the very backbone and nerve of character are lacking too.
79. What’s the main idea of the passage?
A. Self- control is important for a man.
B. We should learn to be strong.
C. A man who keeps cool won’t lose any game.
D. The great heroes in history knew how to control themselves.
80. What does the underlined sentence in Paragraph 2 mean?
A. If you are mad, the gods will kill you.
B. If you lose your temper first, gods will kill you first.
C. If you can’t control yourself, you will be crazy.
D. If the gods want to kill you, they will make you mad first.
81. Which of the following is NOT true, according to passage?
A. The first and best of victories for a man is to conquer himself.
B. You will make a small mistake serious if you don’t keep cool.
C. You must measure a man’s strength by the power of the feelings which conquer him.
D. Anger begins with foolishness and ends with regret.
82. Which of the following can’t help you avoid anger, according to the passage?
A. Being calm in arguing.
B. Checking your temper or anger by speaking low.
C. Keeping your mouth shut.
D. Trying to make the other angry first.

Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, “Mom, I can’t peel potatoes. I have only one hand.”
Mom never looked up from sewing. “You get yourself into that kitchen and peel those potatoes,” she told me. “And don’t ever use that as an excuse for anything again!”
In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.
That night I told Mom about it. She hugged me, and I saw her “we’ll see about that” look. The next afternoon, she took me back to school. At the deserted playground, Mom looked carefully at the bars.
“Now, pull up with your right arm,” she advised. She stood by as I struggled to lift myself with my right hand until I could hold the bar with my other elbow （肘）. Day after day we practiced, and she praised me for every rung （横档）I reached. I’ll never forget the next time, crossing the rungs, I looked down at the kids who were standing with their mouths open.
One night, after a dance at my new junior high, I lay in bed sobbing. I could hear Mom come into my room. “Mom,” I said, weeping, “none of the boys would dance with me.”
For a long time, I didn’t hear anything. Then she said, “Oh, honey, someday you’ll be beating those boys off with a bat.” Her voice was faint. I peeked out from my covers to see tears running down her cheeks. Then I knew how much she suffered on my behalf. She had never let me see her tears.
74. Which can be used to describe Mom’s attitude when she made the child peel potatoes?
A. Cruel.               B. Favourable.        C. Strict.                    D. Sympathetic.

A. Mom believed every aim could be achieved if you stuck to it.
B. The race across monkey bars was not difficult enough for a child to give up.
C. Mom was determined to prove she herself was better than the teacher.
D. What the child had said brought Mom great attraction and curiosity.

_______.
A. they felt sorry for what they had done before
B. they were afraid the author might fall off and get hurt
C. they wanted to see what the author would do on the bars

阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项，并在答题纸上将该项涂黑。
Bill Javis took over our village’s news-agency at a time of life when most of us only wanted to relax. He just thought he would like something but not too much to do, and the news-agency was ready-made. The business produced little enough for him, but Bill was a man who only wanted the simplicity and order and regularity of the job. He had been a long-serving sailor, and all his life had done everything by the clock.
Every day he opened his shop at 6:00 a. m. to catch the early trade; the papers arrived on his doorstep before that. Many of Bill’s customers were city workers, and the shop was convenient for the station. Business was tailing off by 10 o’clock, so at eleven sharp Bill closed for lunch. It was hard luck on anybody who wanted a paper or magazine in the afternoon, for most likely Bill would be down on the river bank, fishing, and his nearest competitor was five kilometers away. Sometimes in the afternoon, the evening paper landed on the doorway, and at 4 o’clock Bill reopened his shop. The evening rush lasted till seven, and it was worthwhile.
He lived in a flat above the shop, alone. Except in the very bad weather, you always knew where to find him in the afternoon, as I have said. Once, on a sunny afternoon, I walked home along the river bank from a shopping trip to the village. By my watch it was three minutes past four, so I was astonished to see Bill sitting there on his little chair with a line in the water. He had no luck, I could see, but he was making no effort to move.
“What’s wrong, Bill?” I called out from the path.
For answer, he put a hand in his jacket and took out a big, golden object. For a moment I had no idea what it could be, and then it suddenly went off with a noise like a fire engine. Stopping the bell, Bill held the thing up and called back, “Ten to four, you see, and this is dead right.”
I had never known anyone carrying a brass alarm clock round with him before.
71. Bill Javis became a news-agent when _______.
A. he needed the money
B. he was quite an old man
C. he decided to take up fishing
D. he gave up clock-repairing
72. Bill opened the shop so early in the day because _______.
A. he liked to do as much as possible before he went to work
B. the shop had to be open when the morning papers came
C. he was never sure of time
D. it was then that he did a lot of business
73. From the information given in the passage, who or what do you think was wrong?
A. The bell was－it must have gone off at the wrong time.
B. Bill was－he had dropped off to sleep.
C. The writer’s watch was－it was fast.
D. Bill’s clock was－it was old.
