Unit 3 What's the weather like? 核心语法精讲精练
第一部分:核心语法梳理
本单元围绕“谈论天气”主题展开,核心是学会用英语询问和描述天气状况、表达温度,以及根据天气选择适当的着装和活动。重点语法知识点有以下三个方面:
语法一:询问天气状况 —— What's the weather like?
基本用法
“What's the weather like?”用于询问某个地方或某个时间的天气状况。What's = What is,like在这里是介词,意为“像……一样”,用于询问天气的特征。
句型结构
- 问句:What's the weather like + (地点/时间)?
- 答句:It's + 天气形容词.
常见天气形容词:
- sunny 晴朗的
- windy 有风的
- cloudy 多云的
- rainy 下雨的
- snowy 下雪的
- warm 温暖的
- cool 凉爽的
- cold 寒冷的
- hot 炎热的
- wet 潮湿的
- dry 干燥的
用法要点:
- 询问天气时,like不能省略。What's the weather? 是不完整或不自然的表达。
- 回答中必须用It's + 形容词,不能说 It rain. 要说 It's rainy. 或 It's raining.
- 地点用介词in连接,时间用介词on或 in连接。
—What's the weather like in Beijing? 北京的天气怎么样?
—What's the weather like in summer? 夏天的天气怎么样?
语法二:一般将来时表示天气预测 —— It will ...
基本用法
在谈论未来的天气时,用will表示“将会……”。will 是情态动词,没有人称和数的变化,后面接动词原形。
句型结构
- 肯定句:It will + 动词原形/be + 天气形容词.
- 否定句:It won't + 动词原形/be + 天气形容词.
- 一般疑问句:Will it + 动词原形/be + 天气形容词?
- 回答:Yes, it will. / No, it won't.
典型例句:
- It will be sunny tomorrow. 明天将是晴天。
- It will rain in the afternoon. 下午将会下雨。
- Will it be cold? 天会冷吗?
- It won't snow today. 今天不会下雪。
will 与 be going to 的区别:
- will 侧重表达预测,可能没有明确的证据。
- be going to 侧重表达计划或已有迹象的推测。
语法三:Let's 提出建议与 Weather activity 搭配
基本用法
Let's = Let us,表示“让我们……吧”,用于提出建议或邀请。后面接动词原形。
句型结构:
- Let's + 动词原形 + 其他.
典型例句:
- Let's go swimming. 我们去游泳吧。
- Let's ride a bike. 我们骑自行车吧。
- Let's go to the park. 我们去公园吧。
易错提醒:
-What's the weather like?中like不能丢:like在这里是介词,意思是"像……一样"。如果把like省掉,句子结构就不完整了。
-询问天气的两种方式:① What's the weather like?
② How's the weather? 两种都是对的,但What's the weather?是错的。
-will vs be going to:will侧重预测,be going to侧重计划或有证据的推测。在天气预报中,will比be going to更常用。
-sunny vs sunny weather:It's sunny today. 句中sunny是形容词;sunshine是名词,指"阳光"本身。
- weather是不可数名词:不能说 a weather,只能说 the weather。
