题目列表(包括答案和解析)

小博士：仔细观察下面的基数词和对应的序数词的区别和变化，你会发现这种变化是有规律的，你能归纳出来吗？请根据规律填出所缺的基数词和序数词，并特别注意黑体字的词。

one	first	eleven	eleventh	twenty-one	twenty-first
two	second	twelve	twelfth	twenty-two	twenty-second
three	third	thirteen	thirteenth	twenty-three	twenty-third
four	fourth	fourteen	fourteenth	twenty-four	______
five	fifth	fifteen	______	twenty-five	twenty-fifth
six	sixth	sixteen	sixteenth	twenty-six	twenty-sixth
seven	______	seventeen	seventeenth	twenty-seven	twenty-seventh
eight	eighth	eighteen	eighteenth	twenty-eight	twenty-eighth
nine	ninth	nineteen	nineteenth	twenty-nine	twenty-ninth
ten	tenth	twenty	twentieth	thirty	thirtieth
thirty-one	thirty-first fortieth ninetieth		hundred	hundredth
forty			thousand	thousandth
ninety			million	millionth

我找到规律了！请看：

1　　英语序数词1～19，除first，second，third等特殊形式外，其余的一般是在相应的基数词后加-th构成。

2　　有几个序数词加-th时拼法不规则，要注意。如fifth，________ ________ ________。

3　　十位整数的序数词的构成方法是先将其基数词的词尾“ty”中的“y”改为“i”，再加“-eth”。如________。

4　　基数词“几十几”变成序数词时，只需将个位数变成序数词，十位数不变。如________。

小词典：大家一定记得以前我们学了one，two，three，four这样一组表示数目的数词，这类词叫基数词。这一单元我们学到了表示顺序的数词，如：first，second，third等，这类词叫序数词。每个基数词有一个对应的序数词。除了一些特殊的变化外，一般是在相应的基数词后加-th构成序数词。序数词前一般要加定冠词，如the first name(第一个名字，名)，the second day(第二天)，CharlesV 查理五世读作Charles the fifth.

Who Is Fooled?

　　Just as the teacher was coming into the classroom, one of the boys, whose name was James, said loudly, “Teacher is a fool．” The teacher pretended not to have heard this．He went up to the platform and said,“ Today we are going to have a lesson on punctuation．Punctuation in a sentence is very important．Look at this sentence．” He picked up a piece of chalk and wrote the following sentence on the blackboard：James says the teacher is a fool．The class laughed．“Now,” continued the teacher, “with two commas I can change the meaning of the sentence entirely．” He then put in two commas and the sentence read：

　　James, says the teacher, is a fool．

　　Notes：

　　1．fool V．愚弄；玩弄，标题中的be fooled是被动语态。n．愚人；傻瓜

　　2．whose的先行词是one of the boys，由whose引出的从句，其前后均有逗点，是非限制性定语从句。

　　3．pretend v．伪装；假装，其后接动词不定式。在句中它后面接not to have heard，表示：老师假装没听见。

　　4．platform n．讲台

　　5．punctuation n．标点；标点使用法，a lesson on punctuation是关于标点使用法的课，这里的on相当于介词about．

　　6．comma n．逗点，entirely adv．完全地。全句可译作：我用两个逗点就能完全改变这话的意思。

　　7．read在这里是过去时，它的意思是：读作：改为。
