教材分析 本课教学内容选自高等教育出版社出版的“十四五”职业教育国家规划教材，《英语 基础模块1》中Unit 5 Celebrations 的语言运用（Language Practice）板块，分为语法（Grammar）和词汇（Vocabulary）两部分，重点讨论现在完成时以及单元重点词汇的用法。现在完成时的相关内容是学生英语学习的一个重点，也是难点内容。
学情分析 学生经过初中阶段的英语学习，以及前期一般现在时态的学习，学生对于英文的一些语法现象有了一定的认识。教师在处理本单元的语法知识的时候，应结合前面几个单元的语法现象，让学生感知不同语言和文化之间思维模式的不同。教师借助这种思维模式，帮助搭建起一般将来时态以及时态学习的知识结构，同时理解将来时态中的一些难点，如be going to和will之间的区别，培养良好的语法习惯。将词汇学习放进具体的语境中，帮助学生掌握词汇的运用。

教学过程
教学环节 教师活动设计 学生活动设计 设计意图
Step 1: Warming up 1.Lead the students to review the usages of the present perfect tense by giving examples and write them down. 2.Read the example sentences in the text, paying attention to the words and phrases in italics. We have learned English for many years.Have you spoken to a foreigner？ FT Clothing and ABC Shopping have been business partners for over ten years. Have you been to a welcome party before Your support has played an important role in our company’s growth. Students recall the relevant knowledge of the present perfect tense and find out the sentences in the present perfect tense in the text. Students list the relevant knowledge of the present perfect tense, preparing for systematizing these fragmented pieces of knowledge in the next step.
Step 2: Language Practice 1.Students watch the grammar micro-lesson video with Unit Four, recall the key knowledge summarized above, and summarize new points. 2.学习语法：现在完成时 在英语时态中，“时”指动作发生的时间，“态”指动作的样子和状态。 定义：过去的动作或状态持续到现在，或对现在造成的影响，可能持续发生下去。 一、构成 现在完成时的基本结构：have/ has + done (过去分词) 动词的过去分词变化规则 （1）一般动词，在词尾直接加“-ed ”：play-played （2）以不发音的“e”结尾的动词，只在词尾加“d ”:live-lived （3）以“辅音字母 + y ”结尾的动词，将 "y" 变为 "i" ，再加“-ed”:study-studied （4）重读闭音节结尾，末尾只有一个辅音字母，先双写该辅音字母，再加“-ed”:stop-stopped （5）不规则变化:get-got-gotten have/ has + done (过去分词) 3. 现在完成时的句子结构: 肯定式：主语+ have/has +过去分词+其他. 否定式: 主语+ haven’t/hasn’t +过去分词+其他. 疑问式：——Have/Has+主语+过去分词+其他？ ——Yes, 主语+have/has . ——No, 主语+ haven’t/hasn’t . 注意：第三人称单数用has 二、用法 表示动作发生在过去某个不确定的时间，但对现在产生了某种影响和结果。常被just, already,yet等副词修饰。 表示从过去某一时刻开始一直持续到现在的动作或状态。常带有for和 since等表示一段时间的状语。 表示说话前发生过一次或多次的动作，现在成为一种经验，或有过一次经历。常带有twice, ever, never, three times等时间状语。 三、标志词 现在完成时的时间状语：现在完成时属于现在时范围，故不能和过去的时间状语连用。 如: yesterday, last,Sunday, in 1990, three years ago等。但是在强调动作产生的后果和影响时，可以和一些表示不确定的时间状语连用。 （1）already & yet 已经 already——肯定句 yet——否定句和疑问句 ever和never。多用于否定或疑问句中，表示“曾经”或“从未”等。 用表示到说话为止的过去时间状语，如just,before, up to now,so far, in the past few years等。 和带有since或for等表示“一段时间”的状语连用，表示动作或状态 从某一时刻开始，一直持续到现在。 since+时间点/句子（一般过去时） for+一段时间=since+一段时间+ago 易混淆点 像buy,die,borrow等终止性动词不能和表示“一段时间”的状语连用。 要用，必须改为“be (在)"等延续性动词来表述。 have been to & have gone to的区别 have been to:去过某地(现在已经回来了)，可与once, never等连用。 have gone to:去某地了(说话时某人不在当地)常用于第三人称。 现在完成时和一般过去时的区别 一般过去时只表示动作发生在过去，与现在无关。 现在完成时强调的是这一动作与现在的关系， 如对现在产生的结果 或影响等。 3.Read and complete. Read the sentences and try to complete them in right form of verbs. 3.Read and match. 1)Work in group to match the sentence with proper adverbials of time.Share the answers and explain the reasons. 2)Ask students to explain the usage of adverbials of time in present perfect. 3)Sum up: for +段时间 since+过去时间点/段时间+ago/一般过去时句子 一般过去时：表示过去发生的动作，不说明现在的情况，强调动作。常用时间标志词：just now、yesterday、last week/night/month…、in 1998、at the age of…等。 现在完成时：过去的事情对现在的影响，强调影响。 4.Think and talk. 1)Teacher talks about your achievement or change this term.

I have already finished reading three books since September. 2)Use the present perfect to communicate with partner about your achievement or changes in knowledge and skills,activities,personal development since the beginning of this term. Students watch the grammar micro-lesson video for Unit Five, recall the key knowledge summarized above, and summarize new points.

Moreover, they are able to describe activities according to the basic usages of the present perfect tense. Meanwhile, they can improve their comprehensive language application abilities and develop the habit of summarization and induction. By observing, comparing, and analyzing the example sentences of the present perfect tense in the grammar section, summarize the usages of the present perfect tense: definition, structure, sentence patterns, rules of participle changes, adverbials of time, easily confused points, tense discrimination, etc., to improve pragmatic ability.
By comparing example sentences, further expand the usages of durative verbs and momentary verbs in the present perfect tense. Activity 15 helps students break through the difficulties in using the present perfect tense by matching sentences in two different tenses with their corresponding adverbials of time, summarizing the adverbials of time for the present perfect tense, and distinguishing the usages of the simple past tense and the present perfect tense. It also improves students' pragmatic ability and helps them develop the habit of summarization and induction.
