<div class="gp-header"><h2>考点1：一般现在时（第三人称单数）</h2><span class="freq">出题频率 ★★★★★</span></div>
<div class="section-card">
<h3>一、三种用法</h3>
<table>
<tr><th>用法</th><th>说明</th><th>示例</th></tr>
<tr><td>习惯性动作</td><td>经常、反复做的事</td><td>I <span class="hl">go</span> to school every day. / She <span class="hl">goes</span> to school every day.</td></tr>
<tr><td>客观事实/真理</td><td>不受时间影响的事实</td><td>The Earth <span class="hl">goes</span> around the Sun. / Water <span class="hl">boils</span> at 100°C.</td></tr>
<tr><td>按时刻表发生</td><td>交通、日程等</td><td>The train <span class="hl">leaves</span> at 8:00 tomorrow. / The class <span class="hl">begins</span> at 9.</td></tr>
</table>
<div class="tip-box"><strong>时间标志词：</strong>always, usually, often, sometimes, never, every day/week/month/year, on Sundays, in the morning</div>
<h3>二、第三人称单数变化规则</h3>
<table>
<tr><th>规则</th><th>变化方式</th><th>示例</th></tr>
<tr><td>一般情况</td><td>加 -s</td><td>play→plays, read→reads, like→likes, run→runs, get→gets</td></tr>
<tr><td>以 s, x, ch, sh, o 结尾</td><td>加 -es</td><td>go→goes, watch→watches, wash→washes, pass→passes, fix→fixes</td></tr>
<tr><td>辅音字母 + y</td><td>变 y 为 i 加 -es</td><td>study→studies, fly→flies, carry→carries, try→tries, worry→worries</td></tr>
<tr><td>元音字母 + y</td><td>直接加 -s</td><td>play→plays, say→says, enjoy→enjoys, buy→buys, pay→pays</td></tr>
<tr><td>特殊</td><td>have → has</td><td>He <span class="hl">has</span> a dog. （不是 haves）</td></tr>
</table>
<h3>三、否定句与疑问句</h3>
<table>
<tr><th>句型</th><th>结构</th><th>示例</th></tr>
<tr><td>否定（I/You/We/They）</td><td>主语 + don't + 动词原形</td><td>I <span class="hl">don't like</span> coffee.</td></tr>
<tr><td>否定（He/She/It）</td><td>主语 + doesn't + 动词<span class="hl">原形</span></td><td>She <span class="hl">doesn't like</span> coffee.（不是 doesn't likes）</td></tr>
<tr><td>疑问（I/You/We/They）</td><td>Do + 主语 + 动词原形?</td><td><span class="hl">Do</span> you like coffee?</td></tr>
<tr><td>疑问（He/She/It）</td><td>Does + 主语 + 动词<span class="hl">原形</span>?</td><td><span class="hl">Does</span> she like coffee?（不是 Does she likes）</td></tr>
</table>
<div class="error-box"><strong>核心规则：</strong>一旦用了 doesn't 或 does/does 开头提问，后面动词必须<span class="hl">还原原形</span>！因为 doesn't/does 已经承担了"第三人称单数"的任务。</div>
<h3>四、易错辨析</h3>
<div class="compare-table">
<div class="wrong-example">He <span class="wrong-hl">go</span> to school every day.</div>
<div class="right-example">He <span class="correct-hl">goes</span> to school every day.</div>
</div>
<p><strong>为什么错：</strong>主语 He 是第三人称单数，在肯定句中动词必须加 -es。学生常看到 "every day" 就想到一般现在时，但忘了动词变化。</p>
<p><strong>错在哪里：</strong>只注意了时态（一般现在时），忽略了主谓一致（第三人称单数需要动词变形）。</p>
<div class="compare-table">
<div class="wrong-example">She <span class="wrong-hl">doesn't likes</span> apples.</div>
<div class="right-example">She <span class="correct-hl">doesn't like</span> apples.</div>
</div>
<p><strong>为什么错：</strong>doesn't 已经是 do 的第三人称单数形式，后面的动词必须<span class="hl">还原原形</span>，不能再加 s。</p>
<p><strong>错在哪里：</strong>双重变形——doesn't 和 likes 同时变化了，而否定句只需要 doesn't 承担变化。</p>
<div class="compare-table">
<div class="wrong-example"><span class="wrong-hl">Does</span> he <span class="wrong-hl">likes</span> music?</div>
<div class="right-example"><span class="correct-hl">Does</span> he <span class="correct-hl">like</span> music?</div>
</div>
<p><strong>为什么错：</strong>疑问句中 Does 已经承担了第三人称变化，后面动词保持原形。</p>
<p><strong>错在哪里：</strong>与否定句同样的"双重变形"错误。</p>
<div class="compare-table">
<div class="wrong-example">My parents <span class="wrong-hl">goes</span> to work by bus.</div>
<div class="right-example">My parents <span class="correct-hl">go</span> to work by bus.</div>
</div>
<p><strong>为什么错：</strong>parents 是复数名词（=they），不是第三人称单数，所以动词用原形。</p>
<p><strong>错在哪里：</strong>误判主语单复数——parents 看起来像单数但实际是复数。</p>
<div class="compare-table">
<div class="wrong-example">The water <span class="wrong-hl">boil</span> at 100°C.</div>
<div class="right-example">Water <span class="correct-hl">boils</span> at 100°C.</div>
</div>
<p><strong>为什么错：</strong>water 是不可数名词，属于第三人称单数，动词要加 s。</p>
<p><strong>错在哪里：</strong>不可数名词（water/milk/bread/news）做主语时等同于第三人称单数。</p>
<div class="rhyme-box">口诀：三单肯定加 s/es，否定疑问用原形！<br>does 开路动词回，别让动词再变形！</div>
</div>
</section>
<!-- 考点2：一般过去时 -->
<section class="grammar-point" id="gp2">
<div class="gp-header"><h2>考点2：一般过去时（不规则动词）</h2><span class="freq">出题频率 ★★★★★</span></div>

<h3>一、三种用法</h3>
<table>

</table>
<div class="tip-box"><strong>时间标志词：</strong>yesterday, last night/week/month/year, ... ago, in 2024, just now, the other day, the day before yesterday</div>
<h3>二、规则动词过去式</h3>
<table>
<tr><th>规则</th><th>变化</th><th>示例</th></tr>
<tr><td>一般加 -ed</td><td>play→played, work→worked, watch→watched</td></tr>

<h3>四、否定句与疑问句</h3>
<div class="error-box"><strong>核心规则：</strong>否定句和疑问句中，用 <span class="hl">didn't / Did</span>，后面的动词<span class="hl">必须还原原形</span>！</div>
<table>
<tr><th>句型</th><th>结构</th><th>示例</th></tr>
<tr><td>否定句</td><td>主语 + didn't + 动词原形</td><td>He <span class="hl">didn't go</span> to school.（不是 didn't went）</td></tr>
<tr><td>一般疑问</td><td>Did + 主语 + 动词原形?</td><td><span class="hl">Did</span> you <span class="hl">see</span> him?（不是 Did you saw）</td></tr>
<tr><td>特殊疑问</td><td>疑问词 + did + 主语 + 动词原形?</td><td>What <span class="hl">did</span> she <span class="hl">do</span> yesterday?</td></tr>
</table>
<h3>五、易错辨析</h3>
<div class="compare-table">
<div class="wrong-example">I <span class="wrong-hl">didn't went</span> to school yesterday.</div>
<div class="right-example">I <span class="correct-hl">didn't go</span> to school yesterday.</div>
</div>
<p><strong>为什么错：</strong>didn't 已经是过去式助动词，后面的动词必须还原为原形 go。</p>
<p><strong>错在哪里：</strong>双重过去化——didn't 和 went 同时变形。这是七年级最高频的错误之一！</p>
<div class="compare-table">
<div class="wrong-example"><span class="wrong-hl">Did</span> she <span class="wrong-hl">saw</span> the movie?</div>
<div class="right-example"><span class="correct-hl">Did</span> she <span class="correct-hl">see</span> the movie?</div>
</div>
<p><strong>为什么错：</strong>与否定句同理，Did 后面跟原形 see，不是过去式 saw。</p>
<div class="compare-table">
<div class="wrong-example">He <span class="wrong-hl">buyed</span> a new bike last week.</div>
<div class="right-example">He <span class="correct-hl">bought</span> a new bike last week.</div>
</div>
<p><strong>为什么错：</strong>buy 是不规则动词，过去式是 bought，不能按规则加 ed。</p>
<p><strong>错在哪里：</strong>将不规则动词当作规则动词处理。</p>
<div class="compare-table">
<div class="wrong-example">I <span class="wrong-hl">have</span> a good time yesterday.</div>
<div class="right-example">I <span class="correct-hl">had</span> a good time yesterday.</div>
</div>
<p><strong>为什么错：</strong>时间标志词 yesterday 表明是过去时，have 必须变为 had。</p>
<p><strong>错在哪里：</strong>看到 yesterday 没有反应过来要变时态。</p>
<div class="compare-table">
<div class="wrong-example">What <span class="wrong-hl">did</span> he <span class="wrong-hl">yesterday</span>?</div>
<div class="right-example">What <span class="correct-hl">did he do</span> yesterday?</div>
</div>
<p><strong>为什么错：</strong>特殊疑问句结构是"疑问词 + did + 主语 + 动词原形"，缺少了动词 do。</p>
<p><strong>错在哪里：</strong>疑问词 what 直接跟了 did，漏掉了主语后面的谓语动词。</p>
<div class="rhyme-box">口诀：过去时，动词变，否定疑问用原形！<br>did 一出动词回，别让 went 再出现！</div>

<!-- 考点3：现在进行时 -->
<section class="grammar-point" id="gp3">
<div class="gp-header"><h2>考点3：现在进行时</h2><span class="freq">出题频率 ★★★★☆</span></div>
<div class="section-card">
<h3>一、三种用法</h3>
<table>
<tr><th>用法</th><th>说明</th><th>示例</th></tr>
<tr><td>正在进行的动作</td><td>此时此刻正在发生</td><td>Look! She <span class="hl">is dancing</span>.</td></tr>
<tr><td>现阶段的活动</td><td>当前一段时间在做</td><td>I <span class="hl">am studying</span> English these days.</td></tr>
<tr><td>将来的计划</td><td>按计划即将发生</td><td>We <span class="hl">are leaving</span> tomorrow.</td></tr>
</table>
<h3>二、现在分词变化规则</h3>
<table>
<tr><th>规则</th><th>变化</th><th>示例</th></tr>
<tr><td>一般加 -ing</td><td>play→playing, read→reading, eat→eating</td></tr>
<tr><td>去 e 加 -ing</td><td>make→making, write→writing, have→having</td></tr>
<tr><td>重读闭音节双写加 -ing</td><td>run→running, swim→swimming, sit→sitting</td></tr>
</table>
<div class="tip-box"><strong>常见需双写的动词：</strong>run, swim, sit, put, cut, get, let, begin, stop, plan, drop, shop, hug, fat→fatten, cut→cutting</div>
<h3>三、一般现在时 vs 现在进行时（核心对比）</h3>
<table>
<tr><th>对比项</th><th>一般现在时</th><th>现在进行时</th></tr>
<tr><td>含义</td><td>习惯性、经常性的动作</td><td>此时此刻正在进行的动作</td></tr>
<tr><td>时间标志词</td><td>always, usually, often, every day</td><td>now, right now, at the moment, Look!, Listen!</td></tr>
<tr><td>结构</td><td>主语 + 动词(原形/三单)</td><td>主语 + am/is/are + doing</td></tr>
<tr><td>示例</td><td>She <span class="hl">reads</span> books every day.</td><td>She <span class="hl">is reading</span> a book now.</td></tr>
<tr><td>示例</td><td>He <span class="hl">plays</span> basketball on Sundays.</td><td>Look! He <span class="hl">is playing</span> basketball.</td></tr>
</table>
<h3>四、易错辨析</h3>
<div class="compare-table">
<div class="wrong-example">Look! He <span class="wrong-hl">plays</span> football.</div>
<div class="right-example">Look! He <span class="correct-hl">is playing</span> football.</div>
</div>
<p><strong>为什么错：</strong>"Look!" 是现在进行时的信号词，表示"快看正在发生的事"，必须用进行时。</p>
<p><strong>错在哪里：</strong>没有识别出 Look/Listen 等提示词，误用了一般现在时。</p>
<div class="compare-table">
<div class="wrong-example">She <span class="wrong-hl">is swiming</span> now.</div>
<div class="right-example">She <span class="correct-hl">is swimming</span> now.</div>
</div>
<p><strong>为什么错：</strong>swim 是重读闭音节词，必须双写 m 再加 -ing → swimming。</p>
<p><strong>错在哪里：</strong>没有判断"是否需要双写"——看最后三个字母是否为"辅-元-辅"且重读。</p>
<div class="compare-table">
<div class="wrong-example">I <span class="wrong-hl">am agree</span> with you.</div>
<div class="right-example">I <span class="correct-hl">agree</span> with you.</div>
</div>
<p><strong>为什么错：</strong>agree 是状态动词，不能用于进行时。类似还有：know, like, love, want, need, understand, believe。</p>
<p><strong>错在哪里：</strong>不是所有动词都能用进行时！状态动词（表示情感、认知、拥有）一般不用进行时。</p>
<div class="compare-table">
<div class="wrong-example">Listen! The bird <span class="wrong-hl">is sing</span>.</div>
<div class="right-example">Listen! The bird <span class="correct-hl">is singing</span>.</div>
</div>
<p><strong>为什么错：</strong>现在进行时结构是 be + doing，sing 必须变为 singing。</p>
<div class="compare-table">
<div class="wrong-example">He <span class="wrong-hl">is writeing</span> a letter.</div>
<div class="right-example">He <span class="correct-hl">is writing</span> a letter.</div>
</div>
<p><strong>为什么错：</strong>write 以不发音的 e 结尾，去 e 加 -ing → writing（不是 writeing）。</p>
<div class="rhyme-box">口诀：Look Listen 在句首，进行时态要跟走！<br>be 动词 + doing，正在发生才管用！</div>

<div class="right-example">I was born <span class="correct-hl">on</span> March 8th.</div>
</div>
<p><strong>为什么错：</strong>March 8th 是具体日期，用 on 不用 in。口诀：in 只管月份不管日。</p>
<p><strong>错在哪里：</strong>看到 March 就条件反射选 in，没注意到后面有 8th。</p>
<div class="compare-table">
<div class="wrong-example">I will meet you <span class="wrong-hl">in</span> Sunday afternoon.</div>
<div class="right-example">I will meet you <span class="correct-hl">on</span> Sunday afternoon.</div>
</div>
<p><strong>为什么错：</strong>星期+上下午 = 具体某一天的上/下午，用 on。</p>
<p><strong>错在哪里：</strong>只看到 afternoon 就选 in，忽略了前面的 Sunday 使其变成了"具体某天"。</p>
<div class="compare-table">
<div class="wrong-example">He goes to school <span class="wrong-hl">by</span> foot.</div>
<div class="right-example">He goes to school <span class="correct-hl">on</span> foot.</div>
</div>
<p><strong>为什么错：</strong>"步行"固定搭配是 on foot，不是 by foot。by 用于交通工具（by bus/by car）。</p>
<div class="compare-table">
<div class="wrong-example">She can write <span class="wrong-hl">by</span> Chinese.</div>

<div class="gp-header"><h2>考点5：代词（人称/物主/不定）</h2><span class="freq">出题频率 ★★★★☆</span></div>

<h3>一、人称代词</h3>

<h3>二、物主代词</h3>
<table>
<tr><th>人称</th><th>形容词性（后接名词）</th><th>名词性（不接名词）</th></tr>
<tr><td>我的</td><td><span class="hl">my</span> book</td><td>The book is <span class="hl">mine</span>.</td></tr>
<tr><td>你的</td><td><span class="hl">your</span> pen</td><td>The pen is <span class="hl">yours</span>.</td></tr>

</table>
<div class="error-box"><strong>辨析要点：</strong>形容词性物主代词后面<strong>必须有名词</strong>；名词性物主代词后面<strong>不能再有名词</strong>。<br>✗ This is mine book. → ✓ This is <span class="correct-hl">my</span> book. / This book is <span class="correct-hl">mine</span>.</div>
<h3>三、不定代词</h3>
<table>
<tr><th>代词</th><th>用法</th><th>肯定句</th><th>否定/疑问句</th></tr>
<tr><td>some / any</td><td>一些</td><td>I have <span class="hl">some</span> books.</td><td>Do you have <span class="hl">any</span> books? / I don't have <span class="hl">any</span> books.</td></tr>

<div class="wrong-example">Please give <span class="wrong-hl">he</span> the book.</div>
<div class="right-example">Please give <span class="correct-hl">him</span> the book.</div>
</div>
<p><strong>为什么错：</strong>give 后面跟的是宾语，需要用宾格 him，不能用主格 he。</p>
<p><strong>错在哪里：</strong>没有判断代词在句子中的位置——动词后面用宾格。</p>
<div class="compare-table">
<div class="wrong-example">This is <span class="wrong-hl">mine</span> pen.</div>
<div class="right-example">This is <span class="correct-hl">my</span> pen. / This pen is <span class="correct-hl">mine</span>.</div>

<p><strong>为什么错：</strong>mine 是名词性物主代词，后面不能再接名词。需要用形容词性 my。</p>
<div class="compare-table">
<div class="wrong-example">Tom and <span class="wrong-hl">me</span> are good friends.</div>
<div class="right-example">Tom and <span class="correct-hl">I</span> are good friends.</div>
</div>
<p><strong>为什么错：</strong>在句中做主语必须用主格 I。me 是宾格，不能做主语。</p>
<p><strong>错在哪里：</strong>中文说"我和Tom"，英文中 A and I 做主语时 I 放后面。</p>
<div class="compare-table">
<div class="wrong-example">Let <span class="wrong-hl">I</span> help you.</div>
<div class="right-example">Let <span class="correct-hl">me</span> help you.</div>
</div>
<p><strong>为什么错：</strong>Let 后面跟宾格，所以是 Let me，不是 Let I。</p>
<div class="compare-table">
<div class="wrong-example">I don't have <span class="wrong-hl">some</span> money.</div>
<div class="right-example">I don't have <span class="correct-hl">any</span> money.</div>
</div>
<p><strong>为什么错：</strong>否定句中用 any 不用 some。some 用于肯定句。</p>
