第七阶段语法速查（对应场景31~33）

已覆盖：将来完成时 / 将来完成进行时 / 关系副词与复杂定语从句 / 非谓语动词综合

【语法48】将来完成时与将来完成进行时

将来完成时表示到将来某一时间为止已经完成的动作；将来完成进行时表示到将来某一时间为止已经持续进行的动作。

常见时间标志：by + 将来时间 / by the time / before + 将来时间

区别：将来完成时强调"完成的结果"；将来完成进行时强调"持续的进程"，常带有感情色彩。

📌 一句话总结

站在未来的某个时间点回头看，描述到那时已经"做完"或"一直在做"的事情。

💡 类比理解

想象你坐时光机来到2030年，回头对朋友说："到那时候，我已经大学毕业了"（将来完成时，强调结果）或者"到那时候，我已经学了十年英语了"（将来完成进行时，强调过程）。就像站在未来的"终点线"回望来时的路。

🗣️ 日常口语例句

1. By the end of this month, I will have finished this project.（到这个月底，我就完成这个项目了。）
2. By next week, we will have been working here for five years.（到下周，我们在这里工作就满五年了。）
3. By the time you get home, I will have cooked dinner.（等你到家的时候，我已经做好饭了。）
4. By 2027, she will have graduated from college.（到2027年，她就大学毕业了。）
5. By tomorrow morning, I will have been waiting for the package for a whole week.（到明天早上，我等这个包裹就整整一周了。）

⚠️ 常见错误

• ❌ By next year, I will finish this project.
  ✅ By next year, I will have finished this project.
  （将来完成时必须用 will have done，不能只用 will do）
• ❌ By the time he comes, I will already leave.
  ✅ By the time he comes, I will have already left.
  （"by the time + 一般现在时"主句要用将来完成时）
• ❌ By next month, I will have been work here for a year.
  ✅ By next month, I will have been working here for a year.
  （将来完成进行时必须用 will have been doing，动词要加 -ing）

🧠 记忆口诀

"将来完成 will have done，结果已现眼前；
将来完成进行 will have been doing，过程持续不断。"

关键词：by / by the time / before + 将来时间点 → 触发将来完成（时）

【语法49】关系副词与复杂定语从句

定语从句除用关系代词引导外，还可用关系副词 where / when / why 引导，它们在从句中作状语。

介词 + which/whom：当关系代词在从句中作介词宾语时，介词可前置。
- The man to whom I spoke is my boss.（= The man who/whom I spoke to）
- This is the house in which I grew up.

非限制性定语从句：用逗号隔开，对先行词作补充说明。
- My brother, who lives in Beijing, is coming to visit.

whose：表示所属关系，既可指人也可指物。
- The city whose history is long attracts many tourists.

📌 一句话总结

用 where/when/why 引导的定语从句，相当于"介词 + which"，在从句中作地点、时间或原因状语。

💡 类比理解

把定语从句想象成给名词贴标签。关系副词 where/when/why 就像三个专门的标签夹：where 夹地点（"在哪个地方"），when 夹时间（"在什么时候"），why 夹原因（"为什么"）。比如"我出生的城市"→"我出生的那个地方"→用 where。

🗣️ 日常口语例句

1. This is the cafe where we first met.（这是我们第一次见面的咖啡馆。）
2. I'll never forget the day when I got my first job.（我永远忘不了得到第一份工作的那天。）
3. That's the reason why I quit smoking.（这就是我戒烟的原因。）
4. The apartment where I grew up is now a museum.（我长大的那间公寓现在成了博物馆。）
5. Do you remember the time when we got lost in Tokyo?（你还记得我们在东京迷路的那次吗？）

⚠️ 常见错误

• ❌ This is the city which I was born.
  ✅ This is the city where I was born. 或 This is the city in which I was born.
  （"出生在城市"需要介词 in，用 where = in which，不能直接用 which）
• ❌ I remember the day which we met.
  ✅ I remember the day when we met. 或 I remember the day on which we met.
  （"在那天见面"需要介词 on，用 when = on which）
• ❌ The reason because he left is unclear.
  ✅ The reason why he left is unclear. 或 The reason that he left is unclear.
  （reason 后面用 why 或 that 引导定语从句，不能用 because）

🧠 记忆技巧

关系副词 = 介词 + which

• where = in/at/on + which（地点）
• when = in/on/at + which（时间）
• why = for + which（原因）

判断方法：看从句中动词是否需要介词。如果动词需要介词搭配（如 born in a city, meet on a day），就用关系副词或"介词 + which"。

【语法50】非谓语动词综合

非谓语动词包括不定式（to do）、动名词（doing）和分词（doing/done）。

接动名词：enjoy, avoid, finish, practice, suggest, consider, keep, mind, risk
接不定式：want, decide, hope, plan, agree, refuse, promise, choose, learn, need
to do / doing 意思不同：stop, remember, forget, try

📌 一句话总结

非谓语动词就是"不能单独作谓语的动词形式"，包括 to do（不定式）、doing（动名词/现在分词）和 done（过去分词），在句中充当除谓语外的各种成分。

💡 类比理解

把动词想象成一个人，谓语是"本职工作"。当这个人不能做本职工作（句子已有谓语）时，就要"兼职"做其他工作——这就是非谓语。to do 像"未来计划"（目的、将要），doing 像"正在进行"（主动、持续），done 像"已经完成"（被动、结束）。

🗣️ 日常口语例句

1. I enjoy reading before bed.（我喜欢睡前看书。）—— enjoy 后接动名词
2. She decided to study abroad.（她决定出国留学。）—— decide 后接不定式
3. Seeing is believing.（眼见为实。）—— 动名词作主语
4. The movie was really exciting.（这部电影真的很刺激。）—— 现在分词作表语
5. I stopped smoking last year.（我去年戒烟了。）—— stop doing 表示"停止做某事"
6. I remembered to lock the door.（我记得要锁门。）—— remember to do 表示"记得要去做"

⚠️ 常见错误

• ❌ I enjoy to read books.
  ✅ I enjoy reading books.
  （enjoy 后面必须接动名词 doing，不能接不定式 to do）
• ❌ She decided going home early.
  ✅ She decided to go home early.
  （decide 后面必须接不定式 to do，不能接动名词 doing）
• ❌ I stopped to smoke during the break.
  ✅ I stopped smoking during the break.
  （stop doing = 停止做某事；stop to do = 停下来去做另一件事。意思完全不同！）
• ❌ To see from the hill, the city is beautiful.
  ✅ Seen from the hill, the city is beautiful.
  （"从山上看"是被动含义，要用过去分词 seen，不能用 to see）

🧠 记忆技巧

接动名词的动词口诀："享受避免 finishes，练习建议 consider，保持介意 keep mind，冒险成功 enjoy"

• enjoy, avoid, finish, practice, suggest, consider, keep, mind, risk

接不定式的动词口诀："想要决定 hope plan，同意拒绝 promise choose，学会需要 want need"

• want, decide, hope, plan, agree, refuse, promise, choose, learn, need

to do vs doing 意思不同的动词：

• stop doing 停止做 / stop to do 停下来去做
• remember doing 记得做过 / remember to do 记得要去做
• forget doing 忘记做过 / forget to do 忘记要去做
• try doing 尝试做 / try to do 努力去做
