一般现在时一般在的用法(1)表示常生或性生的作,用一般在。
如:I often watch TV at home.(2)表示客的事,用一般在。
如: There are seven days in a week.一般在的构成当句子主是 I, we, they, you 或复数名,用原形。
当句子的主是he, she, it 或数名,要用第三人称数的在式形。
具体解:特注意特征 ( often usually always sometimes never seldom every+) 在句子中的志作用,在做最好把他出来。
例子: Sheusually does her homework after dinner.注意区分好人称,第一,二人称和第三人称复数只需要用原形,他的否定形式是“don’t+ 原形”,他的疑形式“Do⋯+ 原形⋯?”如果是第三人称数就要作的化。
例子: They go to work by bus on weekdays.They don’ t go to work by bus on weekdays.Do they go to work by bus on weekdays?于句子中的“doesn’ t+原形”及“Do⋯+ 原形⋯?”分是否定和一般疑句的形式,一旦遇“doesn’t ”“两do个” ,必原。
