单元语法专练
时间的询问及表达
1.时间的询问。
( 1 )英语中常用what time或when对钟表上的时间或某具体时刻进行提问。例如:
—What time do you get up every day?你每天几点起床?
—At six o’clock.六点钟。
( 2 )对日期、月份或年份进行提问时只能用when。例如:
—When is Children’s Day?儿童节是什么时候?
—On June 1st.6月1日。
2.时间的表达。
( 1 )整点的表达:基数词+o’clock,o’clock可以省略。例如:
7:00 读作seven ( o’clock )
( 2 )非整点的表达一般分为两种:
①直读法:由前往后依次读出数字,即先读时钟再读分钟。用基数词表示。例如:
6:20读作six twenty
②区读法:把钟面分成左右两个半区,以分钟数来区分。小于30分钟为右半区,大于30分钟为左半区。右半区:分针数+past+时针数,表示“几点过几分”。左半区:( 60-分针数 )+to+( 时针数+1 ),表示“差几分到几点”。其中30分钟常用half来表示,15分钟常用a quarter来表示。例如:
1:40读作twenty to two
3:30 读作half past three
2:45读作a quarter to three
( 3 )上午和下午的表达:a.m.表示“上午( 午夜12:00后至中午12:00前 )”,p.m.表示“下午( 中午12:00后至午夜12:00前 )”。在使用中常用小写形式,但有时也可使用大写形式。
3.常用的时间介词。
( 1 )at表示在某一时间点,后常接几点几分、天明、中午、日出、日落等。例如:
at five o’clock在五点钟
( 2 )in泛指一般意义上的在上午、下午或晚上以及月或年等较长的时间。例如:
in the evening在晚上
( 3 )on表示在星期几或某一特定的日期、节日。例如:
on a cold afternoon 在一个寒冷的下午
频度副词
1.常见的频度副词有:always( 总是 ),usually( 通常 ),often( 经常 ),sometimes( 有时,偶尔 ),seldom( 很少 ),hardly( 几乎不 ),never( 从不 )等。
2.用法:常用在be动词、情态动词、助动词之后,实义动词之前。例如:
