二、符号、缩写归类法
英语是一种拼音文字,但为了简便,也常用一些符号和缩写的形式来代表单词。
1.符号:$(dollar),¢(cent),£(pound),¥(Renminbi),(pound in weight),&(and),@(at),%(percent),‰(permile),§(selection分节号), (paragraph,段落号)等。
2.缩写:Mr(Mister),A.M。(a.m。)(in the morning),B.C。(BC)(Before Christ),A.D。(AD)(Anno Domini公元。例如A.D.1949,1949A.D。),PRC(the People's Republic of China),UN(United Nations),e.g。(for example),etc。(etcetera等等)等。
三、表示数字和次数的词和词组
数字分整数、分数、小数;算式分加、减、乘、除等。
1.表示整数、次数的词组:个(one),十(ten),百(hundred),千(thousand),万(ten thousand),十万(one hundred thousand),百万(million),千万(ten million),亿(one hundred million),十亿(英one thousand million;美billion),百亿(英ten thousand million;美tenbillion);一次(once),两次(twice),三次(threetimes),四次(four times);第一次(for the first time),第二次(for the second time),第三次(for the third time);上次(last time),这次(this time),下次(next time)等等。
2.分数、小数:one half(),one quarter(),five-eighths(),two and two-fifths(),twopointeight(2.8),zeropointfive(0.5),thirty-five point four two nine(35.429),thirty-nine percent(39%),four permille(4‰)等。
四、正反义词归类法
用正反对照的方法记单词,不仅容易记,用时也比较方便。
例如:
The boy never goes to school late.The boy always goes to school early。(never是always的反义词,late是early的反义词)
The village is quiet and famous.The village is not noisy and unknown。(quiet是noisy的反义词,famous是unknown的反义词)
