一般现在时与现在进行时辨析、天气情景表达
第一部分 语法精讲
语法一:一般现在时 & 现在进行时 精准辨析(单元重难点)
1. 核心用法与场景对比
时态
核心用法
适配场景
高频标志词
一般现在时
1. 长期习惯性、经常性动作;2. 客观真理、自然规律;3. 事物固有特征、常态天气
常态、稳定、反复发生的行为,不局限于当下瞬间
always, usually, often, sometimes, never, every day/season, quite often
现在进行时
1. 此时此刻正在发生的动作;2. 现阶段临时发生的天气、行为
临时、当下、正在进行的场景,非长期常态
now, right now, look!, listen!, at the moment, today
2. 完整句型结构&变形规则
(1)一般现在时
✅ 肯定句:非三单主语+动词原形;三单主语+动词s/es
✅ 否定句:非三单+don’t+动词原形;三单+doesn’t+动词原形(动词还原)
✅ 疑问句:非三单用Do提问;三单用Does提问,动词用原形
变形重点:s/x/ch/sh/o结尾加es,辅音+y结尾变y为i加es
(2)现在进行时
✅ 统一结构:主语+am/is/are+动词ing
✅ 否定句:be+not+doing
✅ 疑问句:be动词提前至句首
变形重点:去不发音e加ing、辅元辅结尾双写尾字母加ing、ie变y加ing
3. 天气专属时态用法(必考)
一般现在时:描述某地长期气候特征(常态)
例:It often rains in summer in the south.(南方夏季常下雨,常态气候)
现在进行时:描述当下正在发生的天气(临时场景)
例:It is raining heavily outside now.(此刻外面正在下大雨)
语法二:天气情景表达(单元核心交际句型)
1. 询问天气的两组万能同义句型
What’s the weather like (today/here)?
How’s the weather (today/here)?
✅ 用法:两句完全等价,可自由转换,适配所有问答场景
✅ 作答规则:统一用形式主语 It 作答,简洁规范
2. 天气词汇分类(状态&动态)
形容词(表天气状态,静态):sunny晴朗的、cloudy多云的、windy刮风的、rainy下雨的、snowy下雪的、hot炎热的、cold寒冷的、warm温暖的、cool凉爽的
动词ing(表天气动态,正在发生):raining正在下雨、snowing正在下雪
3. 高频搭配句型
It’s + 天气形容词.(表当下天气状态)
It’s + 动词ing.(表天气正在发生)
天气+so+形容词,sb. do sth.(天气影响行为)
高频易错点汇总
1. 自然规律、季节常态天气只能用一般现在时;
2. 看到look/listen/now优先用现在进行时,看到often/every优先一般现在时;
3. doesn’t/does提问后动词必须还原原形,禁止用三单;
4. 天气问答不可用they,必须用it指代天气;
5. 进行时必须搭配be动词,不可单独使用动词ing。
