外研版八年级上册现在完成时练习（期末复习）

这是一份外研版八年级上册现在完成时练习（期末复习），共5页。试卷主要包含了基本含义，找出每句中的一处错误并改正，用括号内动词的正确形式填空等内容，欢迎下载使用。
一、基本含义（两个核心）
1. 已完成：过去发生的动作，强调对现在造成的结果或影响
例：I have lst my key.（钥匙丢了 → **现在**无法开门）
2. 未完成：从过去开始，持续到现在的动作或状态
例：We have lived here fr 5 years.（5年前开始住 → **现在**仍住这里）
句型结构
肯定句:主语 + have/has + 过去分词
I have finished my wrk.
否定句: 主语 + have/has + nt + 过去分词
She has nt seen the film.
疑问句:Have/Has + 主语 + 过去分词？
Have yu eaten breakfast?
特殊疑问句:疑问词 + have/has + 主语 + 过去分词？
What have yu dne? |
动词变化规则
1. 规则动词：过去分词 = 动词-ed形式
一般直接+ed:wrk wrked
以e结尾+d：live lived
辅音+y结尾，变y为i+ed：study studied
重读闭音节，双写+ed： stp stpped
拓展：-ed发音规则：
- 清辅音后读 /t/：helped, liked
- 元音/浊辅音后读 /d/：played, lived
- t/d后读 /ɪd/：wanted, needed
2. 不规则动词：必须单独记忆（高频示例）
不规则动词分类记忆法：
AAA型：三态相同 cut-cut-cut, put-put-put
ABB型：过去式与过去分词相同 buy-bught-bught
ABC型：三态不同 g-went-gne, see-saw-seen
ABA型：原形与过去分词相同 becme-became-becme
3. 易错点提醒
瞬间动词不与fr/since连用（需转换表达）：
- 错误：He has died fr 2 years.
- 正确：He has been dead fr 2 years.
- 正确：He died 2 years ag.
常见瞬间动词：buy, brrw, die, leave, jin, marry
have/has的缩写形式：
- have nt → haven't
- has nt → hasn't
- I have → I've
- He has → He's（注意：与He is缩写相同，需根据语境区分）
never, ever的位置**：放在have/has与过去分词之间
- I have never been t Beijing.
- Have yu ever seen snw?
记忆口诀：
现在完成时，have/has加过分
影响现在或持续，时间状语是线索
规则动词加ed，不规则的靠记忆
瞬间动词要注意，fr/since连用要转换
