Tom has been abroad for a week. （2）否定句：主语+haven’t/hasn’t+been+其他. Tom _____ been abroad. （3）一般疑问句：Have/Has+主语+been+其他 Has Tom been abroad Yes, _____ _____. No, _____ _____. （4）特殊疑问句：疑问词+have/has+主语+been+其他 How long has Tina been here hasn't he has he hasn't 2. 用法：动作或状态发生在过去，但它的影响 现在还存在，可以和never, ever, once, twice, three times等副词（短语）连用。 I have never been there. 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.

Have you ever been to a science museum 【解析】ever 副词 意为“曾经” 常与现在完成时连用，位于助动词之后、过 去分词之前。 【注意】ever 反义词为never，意思是：从未，未曾。 当 ever 用于疑问句时，其答语中不用ever，若是否定回答则用never。 【拓展】hardly ever 几乎从不 表示否定意义 We hardly ever go out. 2. Me neither. 【解析】常用于口语中，表示前面所表达的否定情况同样也适合于自己。 Me neither. 与 Me too. 相对。 Me too. 表肯定 Me neither. 表否定 3. Let’s go to one tomorrow. 【解析】Let’s... 意为“让我们...” 【辨析1】 Let’s “让我们...” 表示向对方提建议，包括说话方和听话方在内，其附加问句是shall we Let us “让我们...” 不包括听话方在内，具有请求允许的意味，其附加问句是will you Let’s go fishing, shall we Let us go, will you 【辨析2】one, that, it (1)one 意为“一个人或物”，代替前面提到的同类人或物中的一个。 one代替可数名词单数 ... ...
