易错陷阱1:常见基数词和序数词易混易错点。
【分析】
· hundred, thousand, million, dozen, score等词前有具体数字时,词尾一般不加-s, 不与of连用, 但可与many, a few, several等连用。(如three thousand books; hundreds of books)
· 序数词“第一、第二、第三”单独记;4-19词尾加-th。(易错词:fifth, eighth, ninth, twelfth)
整十序数词辅音字母+y结尾时,变y为i,再加-th。(如twenty twentieth; thirty thirties)
· the+序数词表示“顺序”;a+序数词表示“又,再”。
【规律总结】
at first最初
at first hand直接地
first of all首先
at first sight乍一看
at second hand间接地
first and foremost直接递
a second-hand 二手的
stand first名列第一
second to none首屈一指
a second又一,再一
ten to nine十之八九
twos and threes三三两两,零零星星
易错陷阱2:分数与百分数及主谓一致易混易错点。
【分析】
· 表示分数时,分子用基数词,分母用序数词。分子大于1时,在分母后加-s。(易错点:1/2不能用a second, 应用a/one half)
· 分数、百分数+of+名词作主语时,谓语动词的单复数由of后面的名词而决定。
易错陷阱3:年龄、世纪年代易混易错点。
【分析】
· 表示“某人多大年龄”用“at the age of+基数词”或“基数词+years old”或“基数词+years of age”
· 表示“某人几十多岁时”,用in one’s+整十基数词的复数(如in his thirties)
· 表示“......世纪年代时”,用in the +世纪年代s /世纪年代’s(in the 1980s/1980’s)
易错陷阱4:“一些;许多”的词汇与主谓一致易混易错点。
【规律总结】
只修饰可数名词
a few, quit a few, many, a good many, a large number of, hundreds of, thousands of, millions of, dozens of, scores of作主语时,谓语动词用复数
只修饰不可数名词
a little, quite a little, much, a great of, a large amount of
作主语时,谓语动词用单数
即修饰可数名词也可修饰不可数名词
a lot of, lots of, plenty of, some, the rest of作主语时,谓语动词单复数形式由名词来决定
a large quantity of作主语时,谓语动词用单数
large quantities of作主语时,谓语动词用复数
