Yesterday when he arrived at the airport，he realized that he had forgotten to take his ID card with him．．

Answer 1

分析 Yesterday when he arrived at the airport，he realized that he had forgotten to take his ID card with him．

解答 答案：Yesterday when he arrived at the airport，he realized that he had forgotten to take his ID card with him．
表達(dá)的是昨天yesterday的事情用一般過去時，when引導(dǎo)的時間狀語從句，arrive in/at到達(dá)，the airport是小地點，故用at，故Yesterday when he arrived at the airport，意識到realize，后加that引導(dǎo)的賓語從句，主句he realized that，從句的動作忘記forget發(fā)生在過去的過去，故用過去完成時had+過去分詞，forget的過去分詞forgotten，forget to do sth 忘記去做某事，ID card身份證，隨身帶上take sth with sb，故答案是Yesterday when he arrived at the airport，he realized that he had forgotten to take his ID card with him．

點評 過去完成時（The Past Perfect Tense）：表示過去某一時間或動作以前已經(jīng)發(fā)生或完成了的動作對過去的某一點造成的某種影響或是結(jié)果，用來指在另一個過去行動之前就已經(jīng)完成了的事件．它表示動作發(fā)生的時間是"過去的過去"，側(cè)重事情的結(jié)果．
