Unit 1–3 单项选择高频考点总结

Unit 1  The Changing World（现在完成时 I ＋ 后缀 -ment）

考点 1　现在完成时的基本结构：have/has ＋ 过去分词

表示过去发生的动作对现在造成的影响或结果，常与 already、just、yet、recently、ever、never、so far、in the past few years 等时间状语连用。

教材原句：Many people have already moved into their new houses.（P20）

教材原句：Our school has just built a new gym.（P20）

教材原句：They haven't finished building the road in the park yet.（P20）

⚠ 易错警示：already 只用于肯定句（多在 have/has 之后）；yet 只用于否定句和疑问句（多在句末）；just 在 have/has 与过去分词之间。单选常考三者的"错位摆放"。

例 — Have you finished your homework ______? — Not ______.

【答案】yet; yet　疑问句和否定答语均用 yet。

考点 2　have been to 与 have gone to

教材原句：Where have you been? I have just come back from my hometown.（P20）

教材原句：No, she has gone to Guangzhou with her parents. She hasn't come back yet.（P20）

⚠ 易错警示：have been to 表示"去过（已回）"；have gone to 表示"去了（未回）"。若主语是第三人称且人不在场，选 has gone to；若是"去过某地几次/曾经"，选 have been to。

例 — Where is Mr. Wang? — He ______ to the library. He'll be back soon.

【答案】has gone　人不在场，用 has gone to。

例 I ______ to Beijing twice. It's a beautiful city.

【答案】have been　去过且已回，用 have been to。

考点 3　used to 相关句型辨析

① used to do sth. 过去常常做某事（现在不做了）；② be/get used to doing sth. 习惯于做某事；③ be used to do sth. ＝ be used for doing sth. 被用来做某事（表用途，Unit 3 再次出现）。

教材原句：Have you got used to the life in the city?（P13）

教材原句：People could only write letters or make phone calls in the past.（P11）

⚠ 易错警示：to 的性质不同：used to do 中 to 是不定式符号；be used to doing 中 to 是介词，后接名词或动名词。单选常以 be used to ______ (live/living) 设空。

例 My grandpa ______ live in the countryside, but now he has got used to ______ in the city.

【答案】used to; living　过去常常用 used to do；习惯于用 be used to doing。

考点 4　后缀 -ment（动词 → 名词）

高频词：agree → agreement, argue → argument, pay → payment, move → movement, develop → development, excite → excitement, enjoy → enjoyment, encourage → encouragement。

教材原句：The community reached a(n) agreement to make the place a comfortable home for everyone.（P19）

教材原句：... there has been great development, the memories remain a comfort and an encouragement to me.（P19）

⚠ 易错警示：注意 argue → argument 是去 e 加 -ment；develop 的名词既可加 -ment（development），也是 Unit 3 词形转换考点。单选常考"选名词形式"或"选拼写正确项"。

考点 5　其他高频点

① take place"发生"，不及物，不能用于被动语态。教材原句：A lot of changes have taken place there.（P20）

② 感叹句：What a great change in this area!（P14）—— What ＋ a/an ＋ adj. ＋ 单数名词；How ＋ adj./adv.。单选高频。

③ 交际用语：— How about going swimming together this weekend? — Sounds great!（P13）

Unit 2  Greener Planet, Better Home（现在完成时 II ＋ 前缀 re-）

考点 6　for ＋ 时间段  /  since ＋ 时间点（现在完成时 II 核心）

教材原句：I have kept sorting out all the waste at home for five days.（P38）

教材原句：I have learned a lot about waste sorting since I listened to the speech.（P38）

教材原句：— How long has your city sorted waste? — Since 2020.（P38）

教材原句：I have read her books a whole year.（P43-44）

口诀：for ＋ 一段时间；since ＋ 过去的时间点 / 一般过去时的从句 / "一段时间＋ago"。

例 We haven't seen any waste in the river ______ several months.

【答案】for　several months 是时间段，用 for。

例 I have been in an environmental group ______ the new term began.

【答案】since　从句用一般过去时，用 since。

考点 7　非延续性动词与时间段连用（延续性转换）

现在完成时与 for/since 时间段连用时，句中动词必须是延续性动词。高频转换对：

come/arrive → be (here)；leave → be away；borrow → keep；buy → have；die → be dead；join → be in / be a member of；begin/start → be on。

教材原句：She has volunteered in an environmental organization since last year.（P31）

⚠ 易错警示：单选最爱考：How long ______ you ______ this bike? — For two years. 答案用 have; had（buy→have）。直接选 bought 的选项都是陷阱。
