人教版（2024）七年级上册英语 · 语法知识精讲与配套练习 · Starter Unit 2 Keep Tidy! Starter Unit 2 Keep Tidy! 本单元语法焦点：不定冠词 a/an + 定冠词 the + 方位介词 in/on/under 语法知识详解 一、不定冠词 a / an 的用法 冠词是置于名词之前、说明名词所表示的人或事物的虚词。不定冠词表示"一"的概念。 冠词 用法 示例 a 用在以“辅音音素”开头的词前 a book, a pen, a cup an 用在以“元音音素”开头的词前 an apple, an egg, an hour a 注意：字母u 读音以辅音/j/开头 a useful book, a uniform an 注意：h 不发音时 an hour, an honest boy 判断口诀：不看字母看读音！以元音音素开头用an，以辅音音素开头用a。 • an orange（o是元音音素） vs a one-year-old boy（w是辅音音素） • an MBA（M读作/em/） vs a UFO（U读作/ju:/） 二、定冠词 the 的用法 ① 特指说话双方都知道的人或事物：Where is the teacher? ② 上文已提到过的人或事物：This is a pen. The pen is black. ③ 世界上独一无二的事物前：the sun, the moon, the earth ④ 序数词前：the first day, the second lesson ⑤ 某些固定搭配中：in the morning, play the piano 零冠词（不用冠词）的情况： • 球类/棋类前：play basketball, play chess • 三餐前：have breakfast/lunch/dinner • 学科前：like English/math 三、方位介词 in / on / under 介词 含义 用法说明 例句 in 在……里面 一物体在另一物体的“内部” The book is in the bag. on 在……上面 一物体在另一物体“表面”，有接触 The cap is on the bed. under 在……下面 一物体在另一物体“正下方” The ball is under the chair. 注意事项： ① 方位介词不能单独使用，须与名词/代词构成介词短语 ② 对介词短语提问用 Where：The cat is under the tree. → Where is the cat? ③ 介词短语作表语时，前面要有be动词：The book is on the desk.（× The book on the desk.） ④ a pair of + 复数名词作主语时，谓语用单数：A pair of socks is under the bed. 四、中考高频考点 ① a/an 的判断依据是发音而非拼写：a university, an umbrella ② in the tree（外来物在树上，如鸟）vs on the tree（树本身的东西，如果实） ③ 方位介词 + the/my + 名词：on the desk, under my bed ④ What color + be + 主语? 问颜色：What color is it? — It's red. 配套练习题 单项选择（10题，每题1分，共10分） 1.
