初中英語語法用法講解

  比較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(zhuǎn)換的方法,很容易排除非延續(xù)動詞在有for/since結(jié)構(gòu)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(yīng)改為 Harry got married six years ago. 或 Harry has been married for six years.

  同學(xué)們,看看since和for的用法比較,大家有沒有清楚一點(diǎn)呀,多多看看哦。

  初中英語分詞與連詞的語法

  【分詞與連詞的】在學(xué)習(xí)的時候需要注意的是,分詞的主語和主句的主語必須為同一個哦!

  有時為使分詞短語與主句關(guān)系更清楚,可在分詞前加連詞。 連詞有: when,while,if though,after, before, as. 但分詞的主語和主句的主語必須為同一個,如:

  While waiting there, he saw two pretty girls come out of the building.

  waiting 和saw 的主語相同。

  溫馨提示:同學(xué)對這個如果還不是很理解的話,就不可以再偷懶了哦!
