Unit 6 Weather 单元语法专项-2026-2027学年上学期英语四年级上册（译林版三起新教材）

Unit 6 Weather 单元语法专项-2026-2027学年上学期 英语四年级上册（译林版三起新教材） 第一部分 单元核心语法知识点总结 一、询问与描述天气：What's the weather like? 句型（单元核心语法★★★） 1. 基本概念 What's the weather like? 是英语中询问天气状况最常用的句型，意为"天气怎么样？"，句中 like 是介词，意为"像……"，不是动词"喜欢"。 2. 询问天气的标准句型 - 完整结构：What's the weather like (+ 地点/时间状语)? - What's = What is - 地点前加介词 in：What's the weather like in Nanjing? - 时间前加介词 on：What's the weather like on Sunday? 例：—What's the weather like today? 今天天气怎么样？ —It's sunny. 天气晴朗。 例：—What's the weather like in summer? 夏天天气怎么样？ —It's hot. 天气很热。 3. 描述天气的答语句型 - 结构：It's + 天气形容词 (sunny, rainy, windy, cloudy, warm, cool, hot, cold). - It 指代天气，没有实际意义，是英语中描述天气的固定用法。 - 多个形容词用 and 连接：It's sunny and warm. 例：It's windy and cloudy now. 现在刮风又多云。 例：It's nice and cool in autumn. 秋天凉爽舒适。 4. 天气名词变形容词规则 名词（天气） 形容词（描述天气） 变形规则 sun 太阳 sunny 晴朗的 双写末尾辅音字母 n + y cloud 云 cloudy 多云的 直接 + y rain 雨 rainy 下雨的 直接 + y wind 风 windy 刮风的 直接 + y ⚠️ 记忆口诀：名词后面加 y，就把天气来描述；sun 要双写 n，其他直接加上 y。 5. 两种"下雨"表达 - It's rainy. = It is rainy.（rainy 是形容词，表示"下雨的"状态） - It's raining. = It is raining.（raining 是动词-ing，表示"正在下雨"的动作） 二、情态动词 can 的用法（单元重点语法★★） 1. 基本概念 can 是情态动词，意为"可以、能够"，用来表示能力或可能性。 2. 肯定句结构 主语 + can + 动词原形 + 其他 can 没有人称和数的变化，所有人称后形式都一样。 例：We can fly a kite. 我们可以放风筝。 例：She can swim very well. 她游泳游得很好。 3. 否定句结构 主语 + can not / cannot / can't + 动词原形 + 其他 can not 可缩写为 can't 例：We can't go out. It's rainy. 我们不能出去，下雨了。 例：He can't swim. 他不会游泳。 4. 一般疑问句结构 Can + 主语 + 动词原形 + 其他？ 肯定回答：Yes, 主语 + can. 否定回答：No, 主语 + can't. 例：—Can you share your umbrella with me? 你能和我分享你的伞吗？ —Yes, I can. / No, I can't. 是的，我可以。/ 不，我不能。 5. can 的常见用法 用法 例句 表示能力（会、能够） I can fly a kite. 我会放风筝。 表示许可（可以） You can share my food. 你可以吃我的食物。 表示可能性（可能） It can rain in the afternoon. 下午可能会下雨。 三、单元语法高频考点&易错点总结 易错点 错误示例 正确用法 询问天气句型结构错误 What does the weather like? 只能用 What's the weather like? 天气表达词性混淆 It's rain today. It's rainy today. / It's raining today. can 后接动词形式错误 We can to fly a kite. can 后必须接动词原形，不能加 to can 第三人称变化 He cans swim. can 无人称变化，所有人称后都用 can 名词变形容词漏双写 suny 重读闭音节结尾要双写末尾辅音字母：sunny have/has 人称搭配错误 She have an umbrella. 第三人称单数用 has：She has an umbrella. 四、单元语法问答背诵模板 1. 询问当日天气 A: What's the weather like today?
