この話の内容がいまいち理解できません😔 どなたか詳しく教えて頂けると助かります!!!!!!!!!💧 宜しくお願いします!!!!!!!🙇🏽‍♀️🙇🏽‍♀️

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. The first and older meaning is approximately 今説明 4 las の用法) 'having a personal involvement in', as in otniab neit The second and later, but now much more common, meaning is ‘demonstrating or He is an interested party in the dispute. pd cooig 不説明 1s experiencing curiosity in, enthusiasm for, concern for, as in 和 He is very interested in cricket. (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.

1 On 10 February 2009, at a height of about 800 kilometers above Siberia, an American satellite collided the first such height [háit] satellite [séetalait] collide(d) [kaláid(id)] with an old Russian satellite. It was collision [kaligan] collision in the history of space development. As a result, fragment(s) [fráegmant(s)) debris [dabri:] more than 1,000 fragments of debris were scattered into space. 2 The image above shows the vast amount of space debris in orbit around Earth. Approximately 22,000 vast [váest] orbit [5:rbat] approximately [aprá:ksamatli) objects larger than 10 centimeters across are floating around Earth. Of these, about 16,000 are from known 10 considering [kansidarig) artificial [a:rtafijal] currently [ks:rantli] operation [a:paréifon] Considering that there are only about 1,000 artificial satellites currently in operation, the amount of Sources. space debris is astonishing. This space debris is not only due to the collision of satellites. For example, when rockets reach space, they s 15 leave behind surplus engines and fuel tanks.
