现在完成时 Unit 1 Topic3 语法 2025-2026学年仁爱科普版九年级英语上册

现在完成时Ⅲ 一、延续性动词与非延续性动词 延续性动词：表示可持续的动作或状态 非延续性动词/短暂性动词：表示瞬间完成，结果不可延续的动作；如：buy, die, join · 现在完成时的第二种用法（持续用法）表示一个从过去开始并持续到现在的动作或状态。非延续性动词表示的动作在瞬间就完成了，其结果无法“持续”一段时间。因此，它们不能与表示时间段的 for 或 since 连用。 非延续性动词和延续性动词的转化： ①变为相对应的持续性动词 buy(买) →have borrow(借) →keep put on(穿上) →wear catch a cold (感冒) →have a cold ②转化成be +形容词/ 副词 come/ arrive/ reach (到达) →be here go(去) →be there join (加入) →be in/ be a member of die(死) →be dead begin/ start (开始) →be on fall asleep(入睡) →be asleep finish/ end (结束) →be over marry(结婚) →be married leave(离开) →be away fall ill(生病) →be ill open(开) →be open close(关) →be closed 例：I have had this book for a week. 我这本书买了一周了。 He has been in the army for 2 years. 他在部队已经2年了。 · 非延续性动词的完成时态在否定句中可以和表示一段时间的状语连用 例：I haven’t seen him for a long time. 我已经好久没看到他了。 随堂练习: 同义句转换。 1.

B 解析：句中时间状语 “since last year”（自从去年以来）是现在完成时的标志性时间词，强调动作从过去持续到现在，因此需用 “have/has + 过去分词” 结构。主语 “Many international students” 是复数，故用 “have come”。A 选项（现在进行时）表 “正在发生”，C 选项（一般过去时）表 “过去某个时间发生的动作，与现在无关”，均不符合语境。 2. A 解析：时间状语 “since it came out”（自从它上映以来）提示动作持续到现在，需用现在完成时。“be popular”（受欢迎）是延续性动词短语，其现在完成时结构为 “has been popular”。B 选项（一般现在时）表 “常态或客观事实”，C 选项（一般过去时）表 “过去受欢迎，现在不确定”，均不符合 “从上映持续到现在受欢迎” 的语境。 3. A 解析：时间状语 “so far”（到目前为止）是现在完成时的标志，强调 “截至现在已经看了三次” 的结果，需用 “have seen”。B 选项（一般将来时）表 “计划要做”，C 选项（一般过去时）表 “过去某个时间看了”，均无法体现 “到现在为止的次数”，不符合语境。 4. B 解析：时间状语 “Since last year”（自从去年以来）提示动作从过去持续到现在，需用现在完成时。“offer”（提供）的过去分词是 “offered”，主语 “our school” 是单数，故用 “has offered”。A 选项（一般过去时）表 “过去提供过，现在是否提供不确定”，C 选项（过去进行时）表 “过去某个时刻正在提供”，均不符合 “持续到现在” 的语境。 5. B 解析：问句中 “How long”（多久）提问 “动作持续的时间”，要求谓语动词必须是延续性动词。A 选项 “buy”（买）和 C 选项 “bought”（买，过去式 / 过去分词）均为短暂性动词，无法表示 “持续拥有”；B 选项 “had”（拥有）是延续性动词，且 “has had” 符合现在完成时 “have/has + 过去分词” 的结构，符合语境。 6. C 解析：本题考查现在完成时中 “have been to”“have gone to”“have been in” 的区别： A. have been in：表示 “在某地待了多久”，后接表示时间段的状语（如 for three days），此处 “twice”（两次）是次数，不符合； B. have gone to：表示 “去了某地（还没回来）”，强调 “人不在说话现场”，此处未提及 “是否回来”，且 “twice” 无法搭配该短语； C. have been to：表示 “去过某地（已经回来）”，可搭配次数（如 twice），符合 “游客去过哈尔滨两次（现在已回来）” 的语境。 提升训练 1.
