2. 句式结构与易错点2026
人教版英语八下单元重点知识
句式类型 结构 文档例句
主语 + have/has + 过去 Teng Fei has volunteered at the
肯定句
分词 + for/since... nursing home since last year.
否定句 主语 + haven’t/hasn’t Robert hasn’t volunteered at an
+过去分词 + animal shelter yet.
for/since...
Have/Has + 主语 + 过去 How long has Volunteer 2 been a
疑问句
分词 + for/since...? guide at the museum?
. 易错点提醒：非延续性动词（如 join, start, finish）不能与 for/since 连用，需转化为
延续性动词（如 join→be a member of, start→be）。
例：错误：He has joined the volunteer group for a year.正确：He has been a member of
the volunteer group for a year.
（二）连词 even though/although（让步状语从句）
1. 核心用法
. 表示 “志愿工作中的困难与坚持”：引导让步从句，说明 “尽管存在困难，仍坚持志
愿行为” ，呼应文档中蓝天救援队的精神表述。
例：Even though the volunteer work is unpaid, many people still take part in it because
they want to help others .Although the beach clean-up is tiring, Volunteer 3 has kept
6
doing it for seven years
.
2. 用法注意
. 不能与 but 同时使用：even though/although 本身表 “转折” ，若再用 but 会造成
语法冗余。
例：错误：Although the work is hard, but it’s meaningful.正确：Although the work is
hard, it’s meaningful
.
（三）动词不定式（Infinitives）作目的状语
1. 核心用法2026
人教版英语八下单元重点知识

愿意义” 的重要语法。
例：Volunteers go to the nursing home to help the elderly exercise（ 目的：帮助老人锻
炼） Blue Sky Rescue teaches people safety skills to help them prepare for natural disasters
（ 目的：帮助人们应对灾害）
2. 句式变换
. 否定式：not to + 动词原形，表 “志愿行为需避免的事”。
例：Volunteers need to remember not to talk loudly when visiting the nursing home（避
免大声喧哗）
（四）并列连词 not only...but also...（单元拓展语法）
1. 核心用法
. 表示 “志愿工作的双重影响”：连接 “帮助他人” 与 “自我成长”，体现 “志愿行为的
双向价值” ，贴合文档中 “帮助他人即帮助自己” 的理念。
例：Volunteering not only helps homeless pets find homes, but also helps volunteers learn
to be responsible .Blue Sky Rescue’s work not only saves lives, but also teaches
17
volunteers practical life-saving skills.
2. 用法注意
. 主谓一致：连接两个主语时，谓语动词与 “but also” 后的主语保持一致。
例：Not only the students but also the teacher is going to volunteer at the animal shelter.
