Unit 2语法精讲精练(1)2026-2027学年人教版英语九年级上册
九年级上册 Unit 2 Inspiring People
语法专项精讲精练
第一部分：语法精讲（结合楷模人物、时代热点讲解，贴合单元主题）
本单元核心语法：现在完成时 + have been to / have gone to / have been in 辨析、现在完成时与for/since连用表持续状态，用来讲述榜样人物一生的经历、已经取得的成就、长期坚守的事业，完美匹配“励志人物事迹讲述”的单元主题。
一、基础结构回顾
肯定式：主语 + have / has + 动词过去分词
否定式：主语 + haven’t / hasn’t + 动词过去分词
疑问式：Have / Has + 主语 + 动词过去分词…?
二、三组易混短语（结合榜样热点举例）
短语 核心含义
have been to 去过某地（现在已经返回）
热点例句 ：Yuan Longping has been to many farmlands across China to research hybrid rice.
（袁隆平去过全国众多农田研究杂交水稻，现已结束实地作业）
have gone to 去了某地（当下还在该地，未返回）
热点例句 ：The young researchers have gone to Hainan for rice breeding work.
（青年科研人员去往海南繁育水稻，目前仍在当地）
have been in 待在某地一段时间（常搭配for/since）
热点例句 ：Tu Youyou has been in medical research fields for over 60 years.
（屠呦呦深耕医药研究领域六十余年）
三、for 与 since 用法区分（结合楷模终身奉献热点）
1. for + 一段时间：侧重动作持续的时长 例：
Zhong Nanshan has worked in medical treatment for decades.
（钟南山数十年深耕医疗救治工作）
2. since + 时间点/过去事件：侧重动作开始的起点 例：
He has stuck to public health rescue work since the SARS outbreak in 2003.
学科网（北京）股份有限公司
（自2003年非典爆发以来，他一直坚守公共卫生救援工作）
四、现在完成时&一般过去时再次区分（人物事迹写作高频考点）
现在完成时：看重事迹带来的当下价值、一生累计的成果，无精准过去时间
热点句：Tu Youyou has won the Nobel Prize in Physiology or Medicine.
（获奖这件事至今带给医学界巨大价值）
一般过去时：看重事件发生的具体年份、过去动作本身，搭配明确时间词
热点句：Tu Youyou won the Nobel Prize in 2015.（强调2015这个具体获奖时间）
