1.时间表达法Task2Theexpressionoftime(时间表达方式)一、顺读法：“钟点+分钟”

6:00sixo’clock7：15sevenfifteen

8：45eightforty-five

pre-reading:A:Whattimeisit?

B:Itis______________6:006:406:056:456:136:556:156:30二、逆读法：

1.“分钟+past+钟点”

当分钟小于等于30时，用past，表示几点过几分，past是“过”的意思。如：

2:10tenpasttwo9:30halfpastnine

2.“分钟+to+钟点”。

当分钟大于30时，用to表示“差几分钟到下一个钟点”。to是“差”的意思。如：

1:55fivetotwo10:50tentoeleven
