Question

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.

文章解釋了一種新型理論SPS。
1.主旨大意題。通讀全文可知是關(guān)于SPS的未來的。
2.細(xì)節(jié)題。根據(jù)文章第一句The concept of solar power satellites, or SPS, first put forward in the 1960s, is still not widely known by the general public
3.主旨大意題。通讀第三段可知未來能源缺乏是困擾地球的主要問題。
4.A意為：居安當(dāng)思危；B：本末倒置；C：蘿卜白菜各有所愛。D：說時容易做時難。通讀全文作者未雨綢繆考慮未來能源緊缺的問題，提出了SPS計劃。應(yīng)該選A。
