Step2语法归纳Ⅰ时间的表达法时间可用顺读法或倒读法两种方式表达。例如：5:00 five (o’clock)6:18 six eighteen 或 eighteen past six12:15 twelve fifteen 或 fifteen (a quarter) past twelve4:30 four thirty 或 half past four6:45 six forty-five a quarter to seven （1）直接表达法：钟点+分钟It’s eleven o’clock.It’s seven fifteen. （2）间接表达法◆ 当分钟不超过30分钟，用介词past表示，结构：分钟+past +钟点five past nine = nine five （9:05）fifteen past ten = ten fifteen = a quarter past ten  （10:15）thirty past two = two thirty = half past two （2:30） ◆ 若分钟超过30分钟，用to来表示。差几分到几点，结构：分钟（60-分钟）+ to + 钟点（钟点+1）ten to ten = nine fifty （9:50）fifteen to five = four forty-five = a quarter to five （4:45）【注】① 表示整点时间，直接用基数词表达，后边可接o’clock (也可不加)。表达“几点几分”时，绝不能用o’clock。② 表达“15分”或“45分”时，常用quarter（刻）。 Ⅱ频率副词的使用often, usually, sometimes, always, never等频率副词的位置是系动词、助动词、情态动词之后，实义动词之前。例：I often go to have training classes at weekends.My mother usually makes a big dinner for me when I get the first place in the examination.
