学习目标
掌握动词不定式to + 动词原形的基本结构
熟记后接不定式作宾语的常用动词
正确使用肯定句、否定句和一般疑问句
区分want to do与want sb. to do的用法
在语境和短文中准确运用不定式结构
动词不定式概述
结构为to加上动词原形
在句中可充当及物动词的宾语
表达想要、希望、计划、决定做的动作
形式固定,不随主语人称和数变化
常与表示意愿和计划的动词搭配使用
肯定句结构
主语加谓语动词再接to do加其他成分
不定式紧跟动词后作宾语
动作由句子主语亲自完成
是描述个人计划与意愿的常用句式
适用于一般现在时的日常表达
核心动词(一)
want 想要 后接to do like 喜欢 后接to do
hope 希望 后接to do plan 计划 后接to do need 需要 后接to do
核心动词(二)
decide 决定 后接to do ask 请求 后接to do
agree 同意 后接to do try 尽力 后接to do learn 学习 后接to do
否定句构成规则
借助助动词don’t doesn’t didn’t构成否定
助动词后谓语动词必须使用原形
不定式to do部分保持形式不变
第三人称单数主语搭配doesn’t
过去时态统一使用didn’t进行否定
一般疑问句构成
将助动词Do Does Did放在句首
谓语动词统一使用原形
不定式to do全程不发生变化
答语使用Yes或No加对应助动词
适用于对他人计划和意愿进行提问
重点用法want to do
表示主语自身想要做某事
动作执行者与主语保持一致
结构中to不可省略也不可替换
多用于表达个人愿望与打算
重点用法want sb. to do
表示想要某人去做某事
动作由宾语完成而非主语
结构为want加宾语再加to do
与want to do意义和用法完全不同
常用于提出要求或希望他人行动
使用注意要点
to后面必须接动词原形不能加ing
否定和疑问只改变前面动词形式
不定式本身不受时态和人称影响
看到want hope plan直接使用to do
避免出现want do这类错误结构
like to do与like doing
like to do侧重某次具体想做的事
like doing侧重长期稳定的爱好习惯
本单元重点掌握like to do用法
结合志愿活动场景理解与运用
