第3题

Millions of stars are traveling about in space. A few form. groups which journey together,

but most of them travel alone. And they travel through a universe so large that one star seldom comes near to another.

We believe, however, that some two thousand million years ago, another star wandering through space, happened to come near our sun. Just as the sun and the moon raise tides on the earth, so this star must have raised tides on the surface of the sun. But they were very different from the small tides that are raised in our oceans; a large tidal wave' must have travelled over the surface of the sun, at last forming a mountain so high that we cannot imagine it. As the cause of the disturbance (动荡) came nearer, so the mountain rose higher and higher. And before the star began to move away again, its tidal pull had become so powerful that this mountain was torn to pieces and threw off small parts of itself into space. These small pieces have been going round the sun ever since. They are the planets (行星).

Millions of stars are______.

A．following a regular path in space

B．always travelling together

C．seldom wandering about in the universe

D．moving about without a fixed course

With human footprints on the moon, radio telescopes listening for messages from alien crea

tures (who may or may not exist), technicians looking for celestial and planetary sources of energy to support our civilization, orbiting telescopes' data hinting at planetary systems around other stars, and political groups trying to figure out how to save humanity from nuclear warfare that would damage life and eliminate on a planet-wide scale, an astronomy book published today enters a world different from the one that greeted books a generation ago. Astronomy has broadened to involve our basic circumstances and our mysterious future in the universe. With eclipses and space missions broadcast live, and with NASA, Europe, and the USSR planning and building permanent space stations, astronomy offers adventure for all people, an outward exploratory thrust that may one day be seen as an alternative to mindless consumerism, ideological bickering, and wars to control dwindling resources on a closed, finite Earth.

Today's astronomy students not only seek an up-to-date summary of astronomical facts: they ask, as people have asked for ages, about our basic relations to the rest of the universe. They may study astronomy partly to seek points of contact between science and other human endeavors: philosophy, history, politics, environmental action, even the arts and religion.

Science fiction writers and special effect artists on recent films help today's students realize that unseen worlds of space are real places—not abstract concepts. Today's students are citizens of a more real, more vast cosmos than conceptualized by students of a decade ago.

In designing this edition, the Wadsworh editors and I have tried to respond to these developments. Rather than jumping at the start into murky waters of cosmology, I have begun with the viewpoint of ancient people on Earth and worked outward across the universe. This method of organization automatically (if loosely) reflects the order of humanity's discoveries about astronomy and provides a unifying theme of increasing distance and scale.

This passage is most probably taken from

A．an article of popular science.

B．the introduction of a book of astronomy.

C．a lecture given by the author to astronomy students.

D．the preface of a piece of science fiction.

Astronaut Jim Voss has enjoyed many memorable moments in his career, including three space

flights and one space walk. But he recalls with special fondness a decidedly earthbound experience in the summer of 1980, when he participated in the NASA-AS-EE Summer Faculty Fellowship Program. Voss, then a science teacher at West Point, was assigned to the Marshall Space Flight Center's propulsion lab in Alabama to analyze why a hydraulic fuel pump seal on the space shuttle was working so well when previous seals had failed. It was a seemingly tiny problem among the vast complexities of running the space program. Yet it was important to NASA because any crack in the seals could have led to destructive results for the astronauts who relied on them.

"I worked a bit with NASA engineers," says Voss, "but I did it mostly by analysis. I used a handheld calculator, not a computer, to do a thermodynamic analysis. "At the end of the summer, he, like the other NASA-ASEE fellows working at Marshall, summarized his findings in a formal presentation and detailed paper. It was a valuable moment for Voss because the ASEE program gave him added understanding of NASA, deepened his desire to fly in space, and intensified his application for astronaut status.

It was not an easy process. Voss was actually passed over when he first applied for the astronaut program in 1978. Over the next nine years he reapplied repeatedly, and was finally accepted in 1987. Since then he has participated in three space missions. The 50-year-old Army officer, who lives in Houston, is now in training for a four-month mission as a crew member on the International Space Station starting in July 2000.

Voss says the ASEE program is wonderful for all involved. "It brings in people from the academic world and gives NASA a special property for a particular period of time. It brings some fresh eyes and fresh ideas to NASA, and establishes link with our colleges and universities," Voss explains. "There's an exchange of information and an exchange of perspectives that is very important."

For the academic side, Voss says, the ASEE program also "brings institutions of higher learning more insight into new technology. We give them an opportunity to work on real-world problems and take it back to the classroom. "

Why was the hydraulic fuel pump seal important for the space shuttle？

A．Because previous seals all failed.

B．Because it was very complex in running the space program.

C．Because great care has to be taken of the hydraulic fuel pump sealing.

D．Because any crack in the seals would cause disastrous results for the astronauts.

A Day in the Life of an Astronaut

Italian astronaut Samantha Cristoforetti talks about daily life on the international Space Station(ISS).

For the last few months, my home has been the International Space Station, orbiting 400 km above the surface of the earth, at 25, 000 km per hour. We took off in a Russian Soyuz spaceship from Kazakhstan, and the flight to the Space Station took six hours. (1) I felt incredibly excited.

There are two Americans, three Russians, and me. (2) Fortunately, we all get on well. The day starts for everyone at 7 a.m. There's no gravity up here, so, every morning I float through the cabin to attend our daily planning conference, or DPC. (3) It usually lasts a few minutes. After it's finished. we speak to space centres around the world, including Houston (USA), Munich (Germany) and Tsukuba (Japan).

Then we have breakfast: oatmeal, eggs and coffee. In the past, astronauts had to suck food out of tubes. Nowadays, astronauts' food is served in special individual boxes with covers. (4) Life has become much easier for astronauts over the years.

Our dinner is at around 7.30 p.m. My meals were prepared by an Italian chef on Earth before left, and they're delicious. However, I do exchange a lot of food with my three colleagues from Russia.

(5) Their lentil and vegetable soup is also really good. Of course, I miss fresh food, but a cargo spaceship comes once a month with fresh fruit. When I get back down to Earth, I know I'll miss this peace.

A.I'm the only woman in this group.

B.That was a very long time to live in space.

C.People often ask what food tastes like in space.

D.This stops everything floating away while we eat!

E.On the other hand, the ISS is a perfect environment to do scientific experiments.

F.That's the meeting where we discuss what needs to be done during the day.

G.They like my desserts, and they have a dark bread that I love.

H.I'll never forget looking through the window and seeing it for the first time.

看资料，回答题 The Impossibility of Rapid Energy Transitions [ A ] Politicians are fond of

看资料，回答题

The Impossibility of Rapid Energy Transitions

[ A ] Politicians are fond of promising rapid energy transitions．Whether it is a transition from imported to domestic oil or from coal-powered electricity production to natural-gas power plants， politicians love to talk big．Unfortunately for them （and often the taxpayers）， our energy systems are a bit like an aircraft carrier: they are unbelievably expensive， they are built to last for a very long time， they have a huge amount of inertia （meaning it takes a lot of energy to set them moving ）， and they have a lot of momentum once they are set in motion．No matter how hard you try， you can"t turn something that large on a dime （10美分硬币）， or even a few thousand dimes．

[ B ] In physics， moving objects have two characteristics relevant to understanding the dynamics of energy systems: inertia and momentum．Inertia is the resistance of objects to efforts to change their state of motion．If you try to push a boulder （大圆石）， it pushes you back．Once you have started the boulder rolling， it develops momentum， which is defined by its mass and velocity．Momentum is said to be "conserved，" that is， once you build it up， it has to go somewhere．So a heavy object， like a football player moving at a high speed， has a lot of momentum-that is， once he is moving， it is hard to change his state of motion．If you want to change his course， you have only a few choices: you can stop him， transferring （possibly painfully） some of his kinetic energy （动能） to your own body， or you can approach alongside and slowly apply pressure to gradually alter his course．

[ C ] But there are other kinds of momentum as well．After all， we don"t speak only of objects or people as having momentum; we speak of entire systems having momentum．Whether it"s a sports team or a presidential campaign， everybody relishes having the big momentum， because it makes them harder to stop or change direction．

[ D ] One kind of momentum is technological momentum．When a technology is deployed， its impacts reach far beyond itself．Consider the incandescent （白炽灯的） bulb， an object currently hated by many environmentalists and energy-efficiency advocates．The incandescent light bulb， invented by Thomas Edison， which came to be the symbol of inspiration， has been developed into hundreds， if not thousands， of forms．Today， a visit to a lighting store reveals a stunning array of choices．There are standard-shaped bulbs， flame-shaped bulbs， colored globe-shaped bulbs， and more．It is quite easy， with all that choice， to change a light bulb．

[ E ] But the momentum of incandescent lighting does not stop there．All of those specialized bulbs ledto the building of specialized light fixtures， from the desk lamp you study by， to the ugly but beloved hand-painted Chinese lamp you inherited from your grandmother， to the ceiling fixture in your closet， to the light in your oven or refrigerator， and to the light that the dentist points at you．It is easy to change a light bulb， sure， but it is harder to change the bulb and its fixture．

[ F ] And there is more to the story， because not only are the devices that house incandescent bulbs shaped to their underlying characteristics， but rooms and entire buildings have been designed in accordance with how incandescent lighting reflects off walls and windows．

[ G ] As lighting expert Howard Brandston points out， “ Generally， there are no bad light sources， only bad applications．" There are some very commendable characteristics of the CFL [ compact fluorescent （荧光的） light bulb ]， yet the selection of any light source remains inseparable from the luminaire （照明装置） that houses it， along with the space in which both are installed， and lighting requirements that need to be satisfied．The lamp， the fixture， and the room， all three must work in concert for the true benefits of end-users．If the CFL should be used for lighting a particular space， or an object within that space， the fixture must be designed to work with that lamp， and that fixture with the room．It is a symbiotic （共生的） relationship．A CFL cannot be simply installed in an incandescent fixture and then expected to produce a visual appearance that is more than washed out， foggy， and dim．The whole fixture must be replaced-light source and luminaire-and this is never an inexpensive proposition．

[ H ] And Brandston knows a thing or two about lighting， being the man who illuminated the Statue of Liberty．

[ I ]Another type of momentum we have to think about when planning for changes in our energy systems is labor-pool momentum．It is one thing to say that we are going to shift 30 percent of our electricity supply from， say， coal to nuclear power in 20 years．But it is another thing to have a supply of trained talent that could let you carry out this promise．That is because the engineers，designers， regulators， operators， and all of the other skilled people needed for the new energy industry are specialists who have to be trained first （or retrained， if they are the ones being laid off in some related industry）， and education， like any other complicated endeavor， takes time．And not only do our prospective new energy workers have to be trained， they have to be trained in the right sequence．One needs the designers， and perhaps the regulators， before the builders and operators， and each group of workers in training has to know there is work waiting beyond graduation．In some cases， colleges and universities might have to change their training programs，

adding another layer of difficulty．

[ J ] By far the biggest type of momentum that comes into play when it comes to changing our energy systems is economic momentum．The major components of our energy systems， such as fuel production， refining， electrical generation and distribution， are costly installations that have lengthy life spans．They have to operate for long periods of time before the costs of development have been recovered．When investors put up money to build， say， a nuclear power plant， they expect to earn that money back over the planned life of the plant， which is typically between 40and 60 years．Some coal power plants in the United States have operated for more than 70 years!

The oldest continuously operated commercial hydro-electric plant in the United States is on New York"s Hudson River， and it went into commercial service in 1898．

[ K ] As Vaclav Smil points out， "All the forecasts， plans， and anticipations cited above have failed so miserably because their authors and promoters thought the transitions they hoped to implement would proceed unlike all previous energy transitions， and that their progress could be accelerated in an unprecedented manner．"

[ L ] When you hear people speaking of making a rapid transition toward any type of energy， whether it is a switch from coal to nuclear power， or a switch from gasoline-powered cars to electric cars， or even a switch．from an incandescent to a fluorescent light， understanding energy system inertia and momentum can help you decide whether their plans are feasible．

Not only moving objects and people but all systems have momentum．

第10题

It is a great truth because once we truly understand and accept it. Then life is no lo

nger difficult. Most people do not fully see this truth. Instead they complain about their problems and difficulties as if life should be easy. It seems to them that difficulties represent (代表) a special kind of suffering especially forced upon them or else upon their families, their class, or even their nation.

What makes life difficult is the process of facing and solving problems and it is a painful one. Problems, depending on their nature, cause us sadness or, loneliness or regret or anger of fear. These are uncomfortable feelings, often as painful as any kind of physical pain. And since life causes an endless series of problems, life is always difficult and is full of pain as well as joy.Yet, it is in this whole process of solving problems that life has its meaning. Problems are the serious test that tells us success from failure. When we desire to encourage the growth of human spirit, we encourage the human ability to solve problems, just as in school we set problems for our children to solve. It is through the pain of meeting and working out problems that we learn. As Benjamin Franklin said, "Those things that hurt, instruct." It is for this reason that wise people learn not to fear but to welcome the pain of problems.

1.The main idea of paragraph three is that ().

A、most people feel life is easy

B、the writer feels life is easy

C、the writer likes to complain about his problems

D、Problem solving is part of life

2.The saying from Benjamin Franklin "Those things that hurt, instruct" suggest that ().

A、we do not learn from experience

B、we do not learn when we are pain

C、pain teaches us important lessons

D、pain cannot be avoid

3.According to the passage, we give school children difficult problems to solve in order to ().

A、encourage them to learn
