1) 这阶段最常考的语法难点（你这段里反复出现）
A. 现在完成时 vs 一般过去时
现在完成时：过去发生、对现在有影响/到现在为止的经历
bash
They haven't contacted me for a whole week.（到现在一周都没联系）
I've done this for ten years.（到现在为止做了10年）
I've just begun...（刚刚开始）一般过去时：明确过去时间、已结束
Did you get a good score last year?（last year 强制一般过去时）
常见结构：
for + 一段时间、since + 时间点（常配现在完成时）
since 2020, for ten years
B. 定语从句：which/that/who（你很多句都有）
物：which/that；人：who/that
更自然的口语：能不用就不用，改成简单句更好听也更好说
This is a ruler that I need for math class.（which也对，但口语更常that）
C. apply for / quit / offer benefits（求职高频搭配）
bash
apply for a job（申请工作）
quit a job（辞职）
offer benefits（提供福利）
make decisions（做决定）D. -ing 形容词 vs -ed 形容词
confusing（事情让人困惑） vs confused（人感到困惑）
类似：meaning → mean（刻薄的）；benefines → benefits

① 连读/弱读（Duolingo最常见）
bash
haven't → /ˈhævənt/（t很弱）
contacted me → contacted_me（连在一起）
for a → /fər ə/（像"fə-rə"）
since I → /sɪns aɪ/（贴得很紧）
did you → /dɪdʒə/（听成"didja"）
as soon as → /əz suːn əz/（as 弱读成 /əz/）② 你需要特别听"重音词"
bash
听力不要每个词都抓，抓信息词：contacted / nervous / exams / benefits / applied / manager / since 2020 / land / flavors。4) 你如何"更快"提高听力（第五阶段实用方法）
每天 15--20 分钟，固定三步（最有效）
盲听一遍：只抓关键词（谁、做什么、什么时候、数字）
看字幕/原句对照：把你没听到的连读处圈出来（did you, for a, since I, has worked）
回放 3 次跟读（shadowing）：不暂停，追着音走，重点模仿弱读连读
关键：不是"多听很多遍"，而是"听1遍→对照→模仿→再听1遍验证"。
专门攻你这阶段的三类题
现在完成时（for/since/already/just）
求职面试对话（resume, benefits, apply, quit）
选择/比较（which, favorite, similar/different）
- 口语提升（最省力但见效快）
用"模板句"练到自动化：
bash
've done ... for ...（我做...做了...）
I've ... since ...（从...开始一直...）
I just applied for ...（我刚申请了...）
What benefits do you offer?（你们提供什么福利？）
