3、 saw her.（2001春季高考，14）A.while B.the moment C.suddenly D.once答案：B分析：不少學生誤選D，但“once”隱含條件，意為“一旦就”，該句理解成“我一旦見到他就把錢給了他”顯然不符合上下文的語境，故排除D。“the moment”看似名次詞組，但實際上用作連詞，引導時間狀語從句，故應選B。注意：“once”后面的從句中常可采用省略結構。 Once seeing it (Once you see it )，you can never forget it.Once seen ( = Once it is seen )，it can never

4、 be forgotten.一旦見到了就永遠不會忘記。5. on/upon 名詞/動名次“on/upon”用作介詞，后接名詞或動名詞作賓語，意為“immediately after, at the time of”。 On his arrival at the airport, he was greeted by the Prime Minister. 他一到達機場便受到總理的歡迎。 On inquiring, we found that the plane had already left.經詢問，我們才知道飛機已經飛走了。6. immediately after“immediately a

6、e had no sooner begun than it started raining.比賽剛一開始就下起雨來了。注意：在以上句型中，“hardly/scarcely/barely/no sooner”部分為主句，通常與過去完成時連用；“when/than”部分為時間狀語從句，通常與一般過去時連用。 We had hardly started our journey when the car got a flat tyre. 我們剛出發，車胎就破了。注意：如果將“hardly/scarcely/barely/no sooner”放在句首，則該主句部分必須使用倒裝語序，而“when/than

7、”從句部分語序不倒裝。 Hardly/Scarcely/Barely had the game begun when it started raining.No sooner had the game begun than it started raining. Hardly had we started our journey when the car got a flat tyre.8. the moment  the minute  the instant 在這些結構中，“the moment, the minute, the instant”看似名詞詞組，但實際上用作連詞，引導時間狀語從句。 I recognized him the moment I saw him我一看到他，就認出他來了。 She r
