1.時(shí)間表達(dá)法Task2Theexpressionoftime(時(shí)間表達(dá)方式)一、順讀法：“鐘點(diǎn)+分鐘”

6:00sixo’clock7：15sevenfifteen

8：45eightforty-five

pre-reading:A:Whattimeisit?

B:Itis______________6:006:406:056:456:136:556:156:30二、逆讀法：

1.“分鐘+past+鐘點(diǎn)”

當(dāng)分鐘小于等于30時(shí)，用past，表示幾點(diǎn)過幾分，past是“過”的意思。如：

2:10tenpasttwo9:30halfpastnine

2.“分鐘+to+鐘點(diǎn)”。

當(dāng)分鐘大于30時(shí)，用to表示“差幾分鐘到下一個鐘點(diǎn)”。to是“差”的意思。如：

1:55fivetotwo10:50tentoeleven

注意：15分鐘也可用aquarter表示。Task2Theexpressionoftime(時(shí)間表達(dá)方式)A:Whattimeisit?
