We are,(to a remarkable degree, the right distance from the right sort of star, one e 5 of ten billion and we wouldn't be here now./ We are also fortunate to orbit where we that is big enough to radiate lots of energy, but not so big as to burn itself out swiftly t 1s a curiosity bf physics that the larger a stor the more rapidly it burns.

To appreciate just how narrow, you have only to look at Venus. Venus 1s only ©10 15 twenty-five million miles closer to the Sun than we are. The Sun's warmth reaches it just two minutes before it touches us. In size and composition, Venus is very like Earth, but the small difference in orbital distance made all the difference to (3)how it turned out. It appears that during the early years of the solar system Venus was only slightly warmer than Earth and probably had oceans. But those few degrees of extra 20 warmth meant that Venus could not hold on to its surface water, with disastrous consequences for its climate. As its water evaporated, the hydrogen atoms escaped into space, and the oxygen atoms combined with carbon to form a dense atmosphere of the greenhouse gas CO2. Venus became stifling. Although people of my age will recall a time when astrononmers hoped that Venus might harbor life beneath its padded 25 clouds, possibly even a kind of tropical vegetation, we now know that it is much too fierce an environment for any kind of life that we can reasonably conceive of. Its surface temperature is a roasting 470 degrees centigrade (roughly 900 degrees Fahrenheit), which is hot enough to melt lead, and the atmospheric pressure at the surface is ninety times that of Earth, or more than any human body could withstand We lack the technology to make suits or even spaceships that would allow us to visit Our knowledge of Venus's surface is based on distant radar imagery and som。 disturbing noise from an unmanned Soviet probe that was dropped hopefully into the

次の英文の第2パラグラフ以降の内容を 50 字~ 60 字の日本語に要約 せよ。句読点も字数に含める。 のHideki Shirakawa won the 2000 Nobel Prize for chemistry Tuesday for discovering that plastic can conduct electricity. He is the second Japanese laureate in this field, following Ken-ichi Fukui. 2The fact that Japan has far fewer Nobel laureates in science 5 than other advanced countries like the United States, Britain, Germany and France is indicative of howlittle importance the nation places on basic science. O Although Japan has poured great resources into the development of practical technologies, it has not sufficiently supported basic research. ① The nation urgently needs to develop talented human resources. 10 It must implement policies that will allow young scientists to better concentrate on research, and establish a system that can objectively evaluate the results of their research. ⑤ Basic scientific research in fields such as chemistry and physics tends to garner little public recognition because it is not flashy. It is unfortunate that our citizens do not have a higher regard for the research that has established the foundation upon which our wealthy Saciety is built. 6The fact that Shirakawa won a Nobel Prize suggests that there may be other talented Japanese scientists who have yet to be recognized. We hope that the recognition of Shirakawa's scientific
