【—since和for語法輔導】對于英語since和for的知識講解內(nèi)容,希望同學們都能很好的看看下面的講解內(nèi)容。
since和for
Since 用來說明動作起始時間,for用來說明動作延續(xù)時間長度。例如:
I have lived here for more than twenty years.我住在這兒二十多年了。
I have lived here since I was born. 我從出生起就住在這兒了。
注意:并非有for 作為時間狀語的句子都用現(xiàn)在完成時。
I worked here for more than twenty years. (我現(xiàn)在已不在這里工作。)
I have worked here for many years.(現(xiàn)在我仍在這里工作。)
注意:用句型轉換的方法,很容易排除非延續(xù)動詞在有for/since結構的完成時中的誤用。
1)(對) Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
2)(錯) Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
顯然,第二句不對,它應改為 Harry got married six years ago. 或 Harry has been married for six years.
通過上面對英語since和for用法知識的講解學習,希望同學們都能從中學習的很好,同學們加油吧。
