Have you ever been to Singapore? 3. 辨析 have/has been to + 地点名词 某人曾经去过某地 现在已经回来了，不在那里了 have/has gone to + 地点名词 某人去了某地 现在还没回来，可能在途中或目的地 翻译：他去过上海。___________________________________ 她去上海了。___________________________________ He has been to Shanghai. She has gone to Shanghai. 4. 现在完成时与一般过去时的区别 （1）现在完成时是过去发生的动作对现在造成的影响或结果，强调的是现在的情况。 I saw this film yesterday. （强调看的动作发生过了） I have seen this film. （强调对现在的影响，电影的内容已经知道了） （2）一般过去时常与表示过去的具体的时间状语连用，如：yesterday, last year, ...ago, just now。现在完成时不能与表示过去的时间状语连用。现在完成时的时间状语有：ever, never, just, yet, in the past/last few years, recently, so far等。 改错：Tom has written a letter to his parents last night. ____________________________________ 【练习】 (1) —How many times ____ Carl ____ to the Great Wall? —Only once.
