题目列表(包括答案和解析)

There was great excitement on the planet of Venus(金星) this week. For the first time Venusian scientists managed to land a satellite on the planet Earth, and it has been sending back signals as well as photographs ever since.

The satellite was directed into an area known as Manhattan (named after the great Venusian astronomer Prof. Manhattan, who first discovered it with his telescope 20000 light years ago).

Because of excellent weather conditions and extremely strong signals, Venusian scientists were able to get valuable information as to feasibility (可行性) of a manned flying saucer (碟) landing on Earth. A press conference was held at the Venus Institute of Technology.

“We have come to the conclusion, based on last week’s satellite landing,” Prof. Zog said, “that there is no life on Earth.”

“How do you know this?” the science reporter of the Venus Evening Star asked.

“For one thing, Earth’s surface in the area of Manhattan is made up of solid concrete and nothing can grow there. For another, the atmosphere is filled with carbon monoxide (一氧化碳) and other deadly gases and nobody could possibly breathe this air and survive.” “What does this mean as far as our flying saucer program is concerned?”

“We shall have to take our own oxygen with us, which means a much heavier flying saucer than originally planned.”

“Are there any other dangers that you discovered in your studies?”

“Take a look at this photo. You see this dark black cloud hovering(盘旋) over the surface of Earth? We don’t know what it is made of, but it could give us a lot of trouble and we shall have further tests before we send a Venus Being there.”

“Over here you will notice what seems to be a river, but the satellite findings indicates it is polluted and the water is unfit to drink. This means we shall have to carry our own water, which will add even greater weight to the saucer.”

“If all you say is true, won’t this set back the flying saucer program several years?”

“Yes, but we shall continue as soon as the Grubstart gives us the added funds.” Prof. Zog replied.

During the week of great excitement the Venusian scientists succeeded in getting important information as to ____.

   A. the feasibility of landing a satellite on Earth

   B. the possibility of making a first-rate flying saucer

   C. the feasibility of sending a Venus Being to Earth

   D. the possibility of directing a flying saucer into Manhattan

According to Prof. Zog, the Venusians will have to take their own oxygen with them when they carry out their flying saucer program because ____.

   A. they need it in their way to the planet of Earth

   B. the Earth’s atmosphere is filled with deadly gases

   C. there is a low level of oxygen for Venusians

   D. there is no air on the planet of Earth

The “dark black cloud” on the photo refers to ____.

   A. the polluted air hovering over the surface of Earth

   B. the mass of tiny drops of water floating above Earth

   C. the mass of small things moving through the air

   D. the dark clouds gathering before a storm breaks

The author wishes to call our attention to the fact that ____.

   A. that modern man has polluted his environment to such an extend that he might destroy himself if he went on like this

   B. that there is a point in spending billions to land a flying saucer on Earth

   C. that pollution has become so serous a problem on Earth that even Venusians find life there unbearable.

   D. that it is difficult if not altogether impossible, to land a manned flying saucer on Earth

Lie in bed, by an open window, and listen…
“No air conditioning? How can you sleep?” a friend asks, horrified. I tell her my family has decided to shut the air conditioner off and reduce our electric bill. On this first night of our cost-cutting plan, it’s only 85 degrees. We’re going to suffer, but the three kids complain anyway.
They have grown up in 72-degree comfort, protected from the world outside.
“It’s too hot to sleep,” my 13-year-old daughter complains. “I’m about to die from this heat,” her brother complains down the hall. “Just try it tonight,” I tell them. In truth I’m too tired to turn for long. My face is sweaty, but I lie quietly listening to the cricket choirs outside that remind me of childhood.
The neighbor’s dog howls. Probably a passing squirrel. It’s been years since I took the time to really listen to the night.
I think about grandma, who lived to 92 and still helped with my mom’s gardening until just a few weeks before she died. And then, I’m back there at her house in the summer heat of my childhood. I move my pillow to the foot of grandma’s bed and turn my face toward the open window. I turn the pillow, hunting for the cooler side.
Grandma saw me turn over and over. “If you just watch for the breeze(清风),” she said, “you’ll cool off and fall asleep.” I stare at the filmy white curtain, willing it to move. Lying still, waiting, I suddenly notice the life outside the window. The bug chorus. Neighbors, porch(门廊)-sitting late, speak in unclear words that calm me.
“Mom, did you hear that?” my seven-year-old son cries, “I think it was an owl(猫头鹰)family.”
“Probably,” I tell him, “just keep listening…”
Without the working air conditioner, the house is peaceful, and the natural night noises seem close enough to touch. I hope I’m awake tonight when the first breeze comes in.
【小题1】On the first night of the writer’s cost-cutting plan, her children ______.

A.live a comfortable life as usual

Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unequally heats the surface of the Earth. As hot air rises, cooler air moves in to fill the gap. As long as the sun shines, the wind will blow. And as long as the wind blows, people will manage it to power their lives.
Ancient sailors used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to make electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small part of the world's energy.
Most wind energy comes from turbines that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These devices look like giant airplane propellers(螺桨)on a stick. The wind spins the blades, which turn a shaft connected to a generator.
The biggest wind turbines generate enough electricity to supply about 600 U.S. homes. Wind farms have tens and sometimes hundreds of these turbines lined up together in particularly windy spots, like along a ridge. Smaller turbines set up in a backyard can produce enough electricity for a single home or small business.
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments decrease tax to encourage wind-energy development.
Some people think wind turbines are ugly and complain about the noise the machines make. The slowly rotating blades(螺旋风片) can also kill birds and bats, but not nearly as many as cars, power lines, and high-rise buildings do. The wind is also changeable: If it's not blowing, there's no electricity generated.
Nevertheless, the wind energy industry is increasing sharply. Globally, generation more than quadrupled(四倍) between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes. Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China.
Industry experts predict that if this pace of growth continues, by 2050 the answer to one third of the world's electricity needs will be found blowing in the wind
63. According to the passage, which of the following statements is true?
A. The rotating blades can kill as many birds as high-rise buildings do
B. Single families are not encouraged to build turbines.
C. The USA produces more wind power than any other country in the world.
D. The noise the turbines make may discourage people from building them.
64. The underlined word “generator” in the third paragraph probably means_______.
A. 电动机                       B. 发电机                          C. 机翼                               D. 飞机引擎
65. If the USA wants to build wind turbines in an area with 30,000 homes, how many
should they build at least?
A. 50.                                    B. 150.                                 C. 250.                                 D. 200.
66. All the following are the advantages of wind energy EXCEPT that_________.
A. it is environmentally friendly                                   B. it is free to build and operate
C. the government supports it                                              D. the energy is clean and renewable
