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

0 The English language is full of words which have changed their meanings 3lightly or even dranmatically over the centuries. Changes of meaning can be of a number of I (of の用法)【nice の意味の変遷) different types. Some words, such as nice, have changed gradually. Emotive words tend 例示1企 今例示2 2(文構造) to change more rapidly by losing some of their force, so that awful, which originally とzthe meant ‘inspiring awe', now means Very bad’ or, in expressions such as awfully good, い 5 simply something like *very. In any case, all connection with ‘awe' has been lost. 2 Some changes of meaning, though, seem to attract more attention than others. (0This is perhaps particularly the case where the people who worry about such things 3 (the case where 】 【文構造】 believe that a distinction is being lost. For example, there is a lot of concern at the moment about the words uninterested and disinterested. In modern English, the positive 10 form interested has two different meanings.

(2)It is not a problem that this word has more than one meaning. Confusion never 小理由 seems to occur, largely because the context will normally make it obvious which meaning is intended. In all human languages there are very many words which have more than one meaning- this is a very common and entirely normal (3)state of affairs. Most 20 English speakers, for example, can instantly think of a number of different meanings for the words common and state and affairs which I have just used.
