新概念英语第二册 Lesson 2 · 语法精读与固定搭配分类
本课是一段「星期天睡懒觉被姑母的电话吵醒」的日常记叙，语法主线是 一般现在时与现在进行时的对照、频度副词，以及 介词 on / in / until 的固定搭配。
| 句子 | 语法点 |
|---|---|
| It was Sunday. | 讲故事先交代时间 · be 动词过去式 was，主语 it 指时间 |
| I never get up early on Sundays. | 一般现在时 表示习惯 · never 是频度副词，放在实义动词之前 · on Sundays 泛指每个星期天 |
| I sometimes stay in bed until lunchtime. | sometimes 位置同 never · stay in bed = 躺在床上（不加 the）· until 后接时间点 |
| Last Sunday I got up very late. | 时间状语换成 last Sunday，整句转为过去时（get up → got up） |
| 句子 | 语法点 |
|---|---|
| I looked out of the window. | look out of = 向…外面看 · 规则动词加 -ed：looked |
| It was dark outside. | outside 作副词，放句末 · 与 inside 相对 |
| "What a day!" I thought. | 感叹句 What a + 名词！省略了 it is · thought 是 think 的不规则过去式 |
| "It's raining again." | 现在进行时 is + raining，表示此刻正在下 · 直接引语里保留原时态 |
| Just then, the telephone rang. | ring 的不规则过去式 rang · just then = 就在那时 |
| It was my aunt Lucy. | 打电话的人用 It is / was … 来指认 |
| "I've just arrived by train," she said. | 现在完成时 have + 过去分词，just 放中间 · by train 乘火车 |
| 句子 | 语法点 |
|---|---|
| "I'm coming to see you." | 现在进行时表即将发生的动作（come / go 常用） |
| "But I'm still having breakfast," I said. | still 放 be 动词后、动词前 · have breakfast 吃早饭 |
| "What are you doing?" she asked. | 现在进行时的特殊疑问句 · 主句用过去时 asked |
| "I'm having breakfast," I repeated. | repeat 加 -ed · 与上一句同形，属于课文原句重复 |
| "Dear me," she said. | 感叹语 Dear me! 表示惊讶「天啊」 |
| "Do you always get up so late?" | 一般现在时疑问句 借 do 提问 · always 放实义动词前 |
| "It's one o'clock!" | 整点表达：It's + 基数词 + o'clock |
| 短语 | 用法与例句 |
|---|---|
| get up early / late | 起得早 / 晚；反义短语 stay in bed 赖床 |
| on Sundays | 每逢星期天（泛指）；on Sunday 只指某一个星期天 |
| until lunchtime | 直到午饭时间；not … until 表示「直到…才」 |
| look out of the window | 向窗外看；注意介词是 out of |
| have breakfast / lunch / dinner | 吃三餐，不加冠词；have a good breakfast 才加冠词 |
| by train | 乘火车；同类 by bus / by plane / by car，但 on foot 是步行 |
习惯 用一般现在时 + never / sometimes / always；正在发生 用现在进行时；刚发生 用现在完成时 —— 本课三种时态各就各位。
