三、重點句型
1.it would be many years until australia learnt to respect aborigines and recognise the importance of a diverse society.
很多年之后澳大利亞人才開始尊重土著人，并且意識到多樣性社會的重要性。
it would(will) be +段時間+until+從句是一個句型，表示“過多長時間才……”。
如：
it would be 10 years until he knew the truth
十年之后他才得知真相。
it will be 10 years until you understand
十年后你才會明白。
2.in area it is approximately the same size as the usa (without alaska), which, however, has more than fourteen times as many people.
從面積上說，它大約同美國（不包括阿拉斯加）相當，而美國的人口卻是澳大利亞的十四倍多。
as many people 后面省掉了 it has. 注意倍數表達法。
如a是b的x倍，可表示如下：
a be x times the size/height/length…of b
a be x times as big/high/long as b
a be x-1 times bigger/higher/longer than b
a be bigger/higher than b by x-1 times
3.in his youth charles darwin enjoyed all the freedom to experiment and do whatever he liked.
在年輕時代，查理斯•達爾文可以自由地做試驗及他喜歡做的任何事。
whatever he liked 引導賓語從句，作do的賓語。
