4、undred thirtytwo million two hundred sixtysix thousand and forty three.a:thank you very much. 2.英语中时间的表达方法英语中时间的表达方法主要有直接法和借用介词法等。 (1)直接法。上午八点 eight am (a.m.)ei em下午九点 nine pm (p.m.)pi:em六点六分 six six六点三十二 six thirty two八点正 eight oclock 2)借用介词法。八点四十五a quarter to nine七点零五分five past seven七点五十四six to ei

10、ineteen与ninety,在英文中这几对数词叫做teens and tens(十几与几十)。不管加减还是乘除,这类题中至少会出现两个数字,你的任务就是迅速地判断这两者的关系,然后根据听音再确定正确选项。 (2)加减法计算:在需要简单的加减法计算的题型中,对话中至少出现两个数字,它们之间的关系往往用“多少”、“迟早”、“快慢”、“前后”的形容词、副词或介词短语等来表达。还要注意一些能够表示数的存在或引起数的变化的动词,这些动词也能确定数字之间的加减关系,例如: be, have, start, begin, spend, miss, leave, postpone, prolong, inc

11、rease, add, borrow, lend, loan, delay, save, go up, go down, rate, at x% off the price等。大家还应该记住下面这些表示加减关系的词:more(多),less(少),late(晚),early(早),fast(快),slow(慢),before(前),after(后),add/addition(加上),plus(加上),subtract/ subtraction(减去),minus(减去) dialogue 1:m: this black bag is 2.00 and that blue one is a do
