【互动精讲】
【知识梳理01】一般现在时:
概念:经常、反复发生的动作或行为及现在的某种状况。时间状语:always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays, etc.
基本结构:①be动词;②行为动词
否定形式:
①am/is/are+not;(isn't,aren't)
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。即:
含be动词的一般现在时结构:
含有be动词的一般现在时一般“表示事物或人物的特征、状态”。
如:The sky is blue.
She is very tall.
(1) be 动词的选择
be动词的选择通常根据句子的主语来,一般遵循 “我是am,你是are, is跟着她他它,复数一律都用are”的原则;
当然,there be句型,be动词的确定遵循“就近原则”。
(2) 句型转换
否定句:主语+ be + not +其它。 如:He is not a worker.
