考点速记
考点 01 询问和描述天气
教材原文:What's the weather like today? 今天天气怎么样?
教材原文:It's sunny and hot. 晴朗又热。
解析:What's the weather like? 用来询问天气,回答用 It's + 天气形容词。常见的天气形容词有 sunny, cloudy, rainy, windy, hot, cool, warm 等。
一、问句结构
What's the weather like (today)?
= What is the weather like? 其中 like 意为「怎么样」,不是「喜欢」的意思。
例句:What's the weather like today? 今天天气怎么样?
二、答句结构
It's + 天气形容词.
例句:It's sunny. 晴朗。
It's cloudy. 多云。
It's rainy. 下雨。
It's windy. 刮风。
三、天气形容词的构成
许多天气形容词由名词加 -y 构成:
rain → rainy, wind → windy, cloud → cloudy, sun → sunny (双写 n)
⚠ 易错提醒:What's the weather like? 中 like 不是「喜欢」的意思,而是「怎么样」。回答用 It's + 形容词,不用 It's like + 形容词。如 It's like sunny(×) → It's sunny(✓)。
