解析

小题1:自从20世纪70年代，已经发现了很多和我有关的应用。Applications小题2:和communication, trade.并列的是finance“财政”小题3:我被放进机器人中，被用来制作手机。考查词组“手机”mobile phone小题4:考查词组“as well as”不但，而且，句意：我也被用于医疗手术。小题5:我甚至被用于太空火箭，被用来探索月球和火星。考查动词“探索”explore。小题6:我的目标是给人类提供高质量的生活。考查名词“目标”：goal小题7:词组“of high quality”高质量的，小题8:我非常高兴我是人类的忠诚的朋友和助手。考查形容词“忠诚的”：devoted小题9:“人类” human race(beings)小题10:“人类” human race(beings)小题11:考查词组“如释重负的”in relief  小题12:考查词组“突然笑起来”burst into laughter小题13:我们过去是一个濒危的物种。考查形容词“濒危的”：endangered小题14:考查词组“without mercy”毫不怜悯的小题15:他们说我们破坏了他们的农场。因为主句谓语是said，所以从句也用一般过去式：destroyed

考点

据考高分专家说，试题“Since the 1970s many.....”主要考查你对 [序数词 ]考点的理解。 序数词

序数词的概念：

表示顺序的数称为序数词。如：first, cond, third, fourth。

序数词的构成与用法：

1、序数词的构成：①一般来说，是由相应的基数词加词尾th构成。   例：four＋th→fourth   six＋th→sixth    ven＋th→venth   ten＋th→tenth②下面这些基数词在变为序数词时，有特殊的变化。例：one→first    two→cond    three→third    five→fifth    eight→eighth    nine→ninth    twelve→twelfth③十位整数序数词的构成方法是将基数词的词y变成i，然后再加eth。例：twenty→twentieth    thirty→thirtieth    forty→fortieth    ninety→ninetieth④两位或两位以上的基数词变成序数词时，仅将个位数变成序数词。例：twenty－one→twenty－first    thirty－five→thirty－fifth    a hundred and fifty－three→a hundred and fifty－third2、序数词的用法：①序数词在使用时，一般加上定冠词。例：the first book    the cond floor    the third day    the fourth week．②序数词在多数情况下都用作定语，有的也可以作表语、主语和宾语。例：The may1st is Labour Day. 五月一日是劳动节。    My room is on the cond floor. 我的房间在二楼。    The first is larger than the con.（主语）第一个比第二个大。    Read the book from the first.（宾语）从开头读这本书。    You'll be the sixth to write.（表语）你将是第六个写的。③序数词的前面可以加上不定冠词，用来表示“再一”，“又一”的意思。例：You may have a third try. 你可以第三次尝试。

序数词知识体系：

 

约数的表达方法：

用tens/dozens/scores/hundreds/thousands/millions of 表示“几十、几百、上千、成千上万”等。 如：The boy bought dozens of pencils.       Thousands of people died in the earthquake. 注意： (A)：dozen, score, hundred, thousand, million等表示确切数量时，不用复数。 如：five dozen (of) eggs   五打鸡蛋    hree hundred people  三百个人

分数词的构成和用法：

1）分数词构成法：分数词（FractionalNumerals）由基数词和序数词构成，基数词代表分子，序数词代表分母。除了分子为1的情况下，序数词都要用复数形式：如：1/4：one-fourth    5/9：five-ninths    2/3：two-thirds   17/5：three and two-fifths   7/12：ven-twelfths   379/8：forty-ven and three-eighths此外还有下面表示法：如：1/2：a(one) half    1/4：a(one) quarter    3/4：three-quarters    9/4：two and a quarter    3/2：one and half     31/4：ven and three quarters
