时态与语态.
一、一般现在时:
1,概念:经常、反复发生的动作或行为及现在的某种状况。 2,时间状语:
always, usually, often, sometimes, seldom, every week (day, year, month…), once a week, on Sundays(=every Sunday) , etc.
3.基本结构:①主语+be动词;②主语+行为动词 否定形式:①am/is/are+not;
②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第 三人称单数,则用doesn't,同时还原行为动词。
一般疑问句:①把be动词放于句首;②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。 4,考点:
(1)一般现在时考点分析
①表示客观事实、客观规律和客观真理谚语格言等(不受时态限制) The geography teacher told us the earth moves around the sun. Water boils at 100oC. He said that the earth turns round the sun. Actions speak louder than words. ②表示经常发生、习惯性的动作,与 every day, usually, once a week 等时间状语连用。 He goes to school on foot everyday. We always care for each other and help each other.
