Unit 7 Seasons 专题02 语法提升·易错题专项训练 高频易错点03 时间介词in / on / at的用法 高频易错点01 询问某个季节的气候 高频易错点02 询问他人在某个季节做什么 高频易错点、易错点提示、小练笔、答题点拨 易错精讲 询问某个季节的气候 高频易错点01 想知道天气怎么样，有两把“开锁钥匙”： 1 钥匙一（问某个季节的天气）： What's + 季节 + like? 回答：It's + 形容词 + in + 季节. ② 钥匙二（问今天/某天的天气）： How is the weather (+ 时间)? = What's the weather like (+ 时间)? 回答：It's + 天气形容词. 易错点提示 ★ 两把钥匙都能问天气，但零件不能混：What 后面要跟 like；How 后面不能加 like。 ★ 描述天气用 it 来代指，be 动词一律用 is：It's cold today. 不能写 It am / It are。 ★ 四季“标配”形容词记牢：spring—warm（温暖）、summer—hot（炎热）、autumn—cool（凉爽）、winter—cold（寒冷）。 【例句】 —What's winter like in Harbin? 哈尔滨的冬天怎么样？ —It's very cold in winter. 冬天非常冷。 —How is the weather today? 今天天气怎么样？ —It's sunny and warm. 晴朗又暖和。 小练笔 单项选择。 ( )1. —What's summer like in Nanjing? —It's ____. We often swim. A. cold B. cool C. hot ( )2. —____ is the weather today? —It's sunny. Let's fly kites. A. How B. What C. Where ( )3. —What's the weather like ____ autumn? —It's cool. A. on B. at C. in ( )4. —What's the weather like today? —It ____ sunny. A. are B. is C. am ( )5. We can fly kites when it is ____. A. snowy B. cold C. sunny 点拨 1. 答案：C。 解析：夏天（summer）的“标配”形容词是 hot；cold 是冬天，cool 是秋天，都不合季节特征。 2. 答案：A。 解析：问天气第一把钥匙是 How is the weather?；What 后面必须跟 like 才能问天气；Where 问地点。 3. 答案：C。 解析：季节（autumn）前用介词 in：in autumn 在秋天。 4. 答案：B。 解析：it 代指天气，be 动词用 is：It is sunny. 今天天晴。 5. 答案：C。 解析：放风筝要选晴天，sunny（晴朗的）符合；snowy 下雪的、cold 寒冷的都不适合放风筝。 询问他人在某个季节做什么高频易错点02 想知道别人在某个季节做什么，先看主语“认不认识”： 句型：What do / does + 主语 + do in + 季节? 回答：主语 + 动词短语 + in + 季节.（三单主语的答句，动词也要变三单） ① 主语是 I / you / we / they（“我方人马”）→ 助动词用 do ② 主语是 he / she / it / 单个人名（“单枪匹马”）→ 助动词用 does —What do you often do in autumn? 你在秋天经常做什么？ —I often pick apples with my grandpa. 我经常和爷爷一起摘苹果。 易错点提示 ★ does 问句的答句里，动词要“跟着主语变身”：She swims. / He goes boating.（go 的三单是 goes）。 ★ 助动词后面接动词原形：What does she do...? 里的 do 用原形，不能跟着变 does。 ★ often / usually / sometimes 等频度副词放在动词前面：I often go swimming. 不说 I go often。 【例句】 —What does your sister do in summer? 你姐姐夏天做什么？ —She goes swimming in the sea. 她去海里游泳。 小练笔 单项选择。 ( )1. —What do you ____ in summer? —I often go swimming. A. do B. does C. doing ( )2. —What ____ your sister do in autumn? —She picks apples. A. do B. does C. doing ( )3. He often ____ kites in spring.

A. plant B. plants C. planting 点拨 1. 答案：A 解析：主语 you 是第二人称，助动词用 do：What do you do...? I often go swimming. 我经常去游泳。 2. 答案：B 解析：your sister 是第三人称单数，问句助动词用 does。 3. 答案：B 解析：he 是第三人称单数，fly 要变三单形式 flies。 4. 答案：A 解析：they 是复数主语，动词用原形 make：make snowmen 堆雪人。 5. 答案：B 解析：Helen 是第三人称单数，plant 变 plants：她（常）和同学一起种树。 时间介词in / on / at的用法高频易错点03 把 in、on、at 想成三个大小不同的“时间盒子”，时间词装进对的盒子就不会错： ① in 盒子装“大块时间”：季节、月份、年份、上午/下午/晚上 → in spring / in May / in the morning ② on 盒子装“具体某一天”：日期、星期几、具体某天的早/中/晚、带 Day 的节日 → on Monday / on 1st October / on Sunday morning / on Christmas Day ③ at 盒子装“精确到点的时间”：具体时刻、固定搭配 → at seven / at noon / at night / at weekends / at Christmas 易错点提示 ★ today、this morning、now 这些词前面不加介词：说 today，不说 on today。 ★ “在周末”英式说 at weekends，美式说 on weekends，两种都见过就行。 ★ 节日看情况：on Christmas Day（当天）/ at Christmas（期间）。 【例句】 We have a picnic in spring. 春天我们去野餐。 My birthday is on 15th June. 我的生日在六月十五日。 The film starts at seven o'clock. 电影七点开始。 小练笔 单项选择。 ( )1.
