The concept of solar power satellites, or SPS, first put forward in the 1960s, is still not widely known by the general public. For example, at many public exhibitions about energy, SPS is not even mentioned. This is mainly because very little money has been spent on SPS research
There are people who claim that SPS is unrealistic - because launch costs are much too high today; or because it is too far away. So why do we believe that it is important to continue to do researches on SPS? The reason is very simple.
Humans are going to need huge amounts of electric power in coming decades. Within 50 years the world population is expected to double, while economic growth will continue around the world, especially in the poorer countries. But existing energy sources already face serious problems. They are limited; they are polluted; they are dangerous. So 50 or 100 years from now, where is our power going to come from? Nobody knows. And so we believe that new large-scale possibilities should be studied further.
We must remember that humans have some choices concerning our future. To some extent we can choose the direction in which our civilization develops. And choices that are made in the coming decades - such as the energy sources that we will or will not use, will have major, long-term meaning for human life on earth. We believe that if research continues to show that SPS is environmentally and economically attractive, SPS will open the door to a much more attractive future for human civilization than any ground-based energy source, and one that the public will support and that young people will find challenging and exciting. Furthermore energy from SPS can be readily used in developing countries, as the SPS 2000 project will show, thus aiding economic development worldwide. In addition, by creating large commercial fund for space engineering, SPS will open the frontier of space to economic development, thus creating a limitless new field for the growth of the world economy.
【小題1】Which of the following may be the best title for the passage?
A.The Future Energy- SPS | B.The Concept of SPS |
C.Humans and SPS | D.Advantages of SPS |
A.The research on SPS started in the 1960s is still not appreciated by the public. |
B.The research is showing SPS can benefit environment and economy at present. |
C.The energy from SPS is now being used in some developing countries. |
D.The public don’t know about SPS because little time is devoted to the research. |
A.the present serious energy problems |
B.where to get energy sources in the future |
C.the importance of controlling world population |
D.the need to explore new energy sources |
A.In time of peace prepare for war |
B.Put the cart before the horse |
C.One man’s meat is another man’s poison |
D.Easier said than done |

The largest earthquake ( magnitude里氏 9.5) of the 20th century happened on May 22, 1960 off the coast of South Central Chile. ?
It generated(生成) one of the most destructive Pacific wide tsunamis(海嘯). Near the generating area, both the earthquake and the tsunami were very much destructive, particularly in the coastal area from Concep-cion to the south end of Isla Chiloe. The largest tsunami damage occurred at Isla Chiloe -----the coastal area closest to the epicenter(震中). Huge tsunami waves measuring as high as 25 meters arrived within 10 to 15 minutes after the earthquake, killing at least two hundred people, sinking all the boats, and flooding half a kilometer inland. ?
There was large damage and loss of life at Concep-cion, Chile's top industrial city. Near the city of Valdivia, the earthquake and following aftershocks generated landslides which killed 18 people. At the port city of Valparaiso, a city of 200,000, many buildings collapsed . A total of 130,000 houses were destroyed one in every three in the earthquake zone and nearly 2,000,000 people were left homeless.?
Total damage losses, including to agriculture and to industry, were estimated(估計(jì)) to be over a half billion dollars . The total number of death related with both the tsunami and the earthquake was never found accurately for the region. Estimates of deaths reached between 4,900 to 57,002 with no distinction(差別) as to how many deaths were caused by the earthquake and how many were caused by the tsunami. However, it is believed that most of the deaths in Chile were caused by the tsunami.
1.Where did the largest tsunami damage occurred? ?
A. Concep--cion. B. Isla Chiloe. C. Valdivia D. Valparaiso.
2.What can we learn about the tsunami waves generated by the earthquake? ?
A. The tsunami waves as high as 25 meters arrived immediately after the earthquake.
B. The tsunami waves killed 200 people and sank all the boats. ?
C. The tsunami waves were very destructive. ?
D. The tsunami waves flooded half of the inland.
3.What is the total number of deaths in the earthquake? ?
A. About 2,000,000. B. Between 4,900 to 57,002.?
C. About 200,000. D. It was hard to know.
4.What does the underlined word "collapsed" in the third paragragh probably mean ?
A. was destroyed B. caught fire C. was flooded D. sank
