Unit1 What is art?语法讲解与练习 语法:现在完成时（just/already/yet/still） 一、现在完成时 超详细语法讲解 1. 现在完成时核心概念 现在完成时用来表示发生在过去，但对现在有影响、有结果、有状态遗留的动作。 重点：不看过去什么时候发生，只看现在的结果。 两大核心用法： ① 完成用法：动作已经做完，现在有结果。（我已经做完作业了） ② 延续用法：动作从过去开始，一直持续到现在。（我一直喜欢艺术） 2. 现在完成时 完整结构 肯定句：主语 + have/has +过去分词 否定句：主语 + haven’t/hasn’t +过去分词 一般疑问句：Have/Has +主语+过去分词 …? 人称规则：I/you/we/they 用 have；he/she/it/单数名词用 has。 二、四大标志词【just / already / yet / still】逐词讲解 1. just （刚刚） 词义：刚刚、方才 使用句式：只能用于肯定句 固定位置：have/has 后，过去分词 前 语义详解：强调动作几秒、几分钟前刚刚完成，时间非常近，侧重“刚做完”。 I have just finished my art homework. 我刚刚完成我的美术作业。 She has just visited the art gallery. 她刚刚参观完美术馆。 2. already （已经） 词义：已经 使用句式：主要用于肯定句；可用于疑问句表惊讶（居然已经……？）；绝对不用于否定句 固定位置：have/has 之后、过去分词之前，也可放句末 语义详解：动作早已经完成，比预期更早、更快，强调“早已做完”。 We have already learned about visual art. 我们已经学习了视觉艺术。 He has finished the painting already. 他已经画完这幅画了。 3. yet （还 / 已经） 词义：（否定句）还未；（疑问句）已经 使用句式：只用于否定句、疑问句，不用于肯定句 固定位置：只能放在句末 语义详解：否定句表“到目前为止还没做”；疑问句表“到现在做了吗？” （否定）：I haven’t seen this artwork yet. 我还没有看过这件艺术品。 （疑问）：Have you learned creativity skills yet? 你已经学完创造力技巧了吗？ 4. still （仍然、依旧） 词义：仍然、依然、仍旧 使用句式：肯定句、否定句均可使用 固定位置（超级必考）：放在 have/has 的前面（和 just/already 完全相反） 语义详解：强调状态、动作一直没变、持续到现在，仍然保持原样。 （肯定）：I still have great love for art. 我仍然热爱艺术。 （否定）：He still hasn’t understood the meaning of the sculpture. 他依旧不理解这座雕塑的含义。 三、四大标志词终极对比总结 ✅ just：肯定句、助动词后、刚刚做完 ✅ already：肯定句、助动词后、早已做完 ✅ yet：疑问/否定、句末、尚未/已经 ✅ still：肯定/否定、助动词前、仍然没变 【专项练习】 大题一、单项选择 1.
