2026年中考英语语法之时间状语从句课件

初中英语语法 时间状语从句 中考考情分析 题型 出现频率 考查形式与核心考点 单项选择 ★★★★★ （最高） 1.连接词选择：when/while/as/until/since等 2.时态判断：重点考查“主将从现”原则 完型填空 ★★★★ （较高） 考点与单选类似，但更依赖上下文逻辑。 词汇运用/ 语法填空 ★★★ （中等） 1.给出动词，要求根据主句时态填写从句动词 的正确形式。 2.给出连接词提示，填写完整句子。 句子改写/合并 ★★ （较低，但重要） 要求用指定的时间状语从句连接词将两个简单句合并成一个复合句。 书面表达 （作文） ★★★★★ （隐形高分考点） 不直接考查，但高级用法是重要的加分项。使用时间状语从句可以使文章逻辑连贯，结构丰富。 什么是时间状语从句？ I will call you when I get home. Please turn off the lights before you leave. The phone rang when I was taking a shower. 当我正洗澡的时候，电话铃响了。 As I answered the phone, I spilled my coffee. 我一边接电话，一边把咖啡弄洒了。 什么是时间状语从句？ 用一个句子（从句）来表示主句动作发生的时间。这个句子就是时间状语从句。 一、基础组： when: 当…时候（可指时间点，也可指时间段） When I arrived, he was cooking. 我到达的那个时间点，他正在做饭。 While: 当…时候（强调一段时间，从句动词常为持续性动词） While he was cooking, I was reading. 在他做饭的整个期间，我都在看书。 常见连接词大盘点 基础组：when, while, as, before, after 进阶组：as soon as, until, since, by the time, whenever as 一边…一边…（强调主从句动作同时进行） As he walked, he sang. 他一边走路一边唱歌。 before: 在…之前 Did she leave a message before she went? 她走之前留言了吗？ after 在…之后 I'll call you after I've spoken to them. 我和他们谈了以后就给你打电话。 连接词 核心含义 侧重角度 从句动词特点 典型语境与考点 when 当…时候 时间点或时间段。 最通用，使用最广泛。 延续性动词或 短暂性动词均可。 1.表示“某个时间点”。 2.“正在…突然…”结构 （中考高频考点） while 在…期间 时间段，强调动作的 持续性。 必须是延续性动词。 1.表示“在某整个过程中” 2.强调两个长动作同时进行。 as 一边… 一边… 动作的平行发生，强调“伴随”或“变化”。 延续性动词或 短暂性动词均可。 1.表示“随着”某个动作 发生另一个动作。 2.表示“两种情况 同时变化”。 when, while, as用法区别 When I arrived (短暂), he was cooking.
