Unit 1 Grammar Fcus
01 一般过去时 (Simple Past)
核心：描述过去某特定时间发生的动作，动作已结束，与现在没有直接关联。
结构公式：主语 + 动词过去式 (V-ed)
例句：I visited the museum last Sunday.(只说明上周日做过这件事，与现在无关)
02 现在完成时 (Present Perfect)
核心：强调动作对现在造成的影响或结果，或动作持续到现在，不强调具体时间。
结构公式：主语 + have/has + 过去分词 (V-pp)
例句：I have visited the museum.(暗示我了解博物馆，或我刚回来，影响现在)
? 快速区分法：看到“昨天、去年、刚才”等明确过去时间，选一般过去时；看到“已经、从未、到目前为止”或强调现在结果，选现在完成时。
1. 清晰识别一般过去时与现在完成时的核心区别。2. 熟练掌握used t d结构的用法与含义。3. 准确记忆并变换常见动词的过去式和过去分词。
1. 独立完成 4b 和 4c 的填空与语法练习。2. 能用两种时态生动描述家乡的变化与发展。3. 在口语对话中自信运用所学句型交流。
1. 体会家乡变迁背后的时代进步与发展。2. 激发对家乡的热爱，懂得珍惜当下的幸福生活。3. 乐于用英语分享个人成长与家乡故事。
“Change is the nly cnstant in life, let's express it in English!”
Warming-up: Review
Lk at these tw sentences:
01. The Past (20 years ag)"It tk half a day t reach the twn."?? 过去到达镇上要花费整整半天的时间。
02. The Present (Nw)"It takes nly an hur nw."?? 现在只需要一个小时就能到达镇上。
What's the key difference?
? 语法点睛：当句子中出现明确的过去时间状语（如 20 years ag, yesterday 等）时，谓语动词需要使用一般过去时 (Simple Past Tense)，动词形式会发生相应变化。
Grammar Rules (frm 4a)
? 关键信号词：20 years ag, in the past, yesterday, last night? 核心用法：表示动作发生在过去某一特定时间，且已经结束，与现在无关。? 经典例句：Hebecamea dctr10 years ag.
? 关键信号词：fr ages, just, ever, since, already, yet? 核心用法：动作发生在过去，但强调对现在造成的影响或结果，无明确过去时间点。? 经典例句：Shehas just finishedher hmewrk.
✨ 记忆小口诀 (Cheat Sheet)
? 看到 ag / yesterday / in the past →动词变过去式 (V-ed)
? 看到 fr / since / just / ever →have/has + 过去分词 (dne)
Key Pint: used t d
01 Meaning 含义表示过去经常发生的动作或存在的状态，但现在已经不再如此。英文释义：Did smething ften in the past (but nt nw).
02 Structure 结构核心公式：used t + 动词原形 (d)注意：无论主语是I/He/She/They，结构不变。
03 Example 例句：Many peple used t wrk in big cities.（翻译：过去很多人常常在大城市工作，现在可能已经回到家乡或换了工作。）
⚠️ 易错警示 (Dn't Make This Mistake!)✅ 正确：She used t live in Paris. (用动词原形 live)❌ 错误：She used t lived in Paris. (绝对不要加过去式！这是初学者最容易踩的坑。)
Practice 4b: Cmplete the cnversatin

4b: Check Answers
01. Staying in GuizhuB: I've been t Guizhu. I have been(be) there fr tw weeks.? Key: "fr + 时间段" 强调动作持续 →现在完成时
02. Visiting GrandparentsB: I visited them. They mved(mve) there last year.? Key: "last year" 是过去的时间点 →一般过去时
03. New HspitalB: Great! A new hspital pened(pen) last Friday.? Key: "last Friday" 是具体的过去时间 →一般过去时
04. Never VisitedA: I have never visited(never visit) Guizhu.? Key: "never" 强调从未有过的经历 →现在完成时
Practice 4c: Cmplete the passage
01. In the past （一般过去时）
1. Peple in Guizhu ________ (live) a hard life.2. They ________ (nt have) enugh fd.3. Children ________ (nt g) t schl.
02. Nw （现在完成时 / 一般现在时）
4. Great changes ________ (take) place.5. Peple ________ (build) new rads and huses.6. They ________ (live) a happy life nw.
Key Tips (给基础薄弱同学的小提示)
① 找时间标志：In the past是过去时信号，动词用过去式 (如 lived, had)；Nw是现在/完成时信号。② 注意否定句：过去时否定用didn't + 动词原形(如 didn't have)。③ 检查动词：不规则变化需牢记 (g → went; build → built)。
