天津小学生英语连词用法——and but or so让作文更流畅
天津小学生英语连词学习指南，系统讲解and/but/or/so等常用连词的用法区别和搭配规则，搭配写作练习和常见错误分析，帮孩子的英语写作更连贯流畅。
很多天津小学生写英语作文时是这样的——“I have a dog. It is white. It is small. It is cute. I like it.” 全篇短句堆砌，像一年级孩子的说话水平。同样是写狗，换成：“I have a dog. It is white and small, and it is very cute, so I like it very much.” 加了and和so，立刻不一样了。
这个”魔法”就来自英语连词——and、but、or、so、because、when等。它们就像是句子的”胶水”，能把一个个孤立的短句子粘成丰富流畅的长句子。胡老师（edu_yujia）发现，天津小学生英语作文中60%以上的扣分点和”句子连接”有关——要么通篇短句不断，要么想写复合句却语法错误百出。
适合：天津小学三年级到六年级学生 目标：系统掌握小学阶段核心连词，写出更流畅的英语作文
小学阶段最核心的6个连词
1. and——“和，而且”
and是最简单也最常用的连词，连接两个并列的成分（单词、短语或句子）。
用法①：连接两个并列的词
- I like apples and bananas.
- She is tall and thin.
- The cat is black and white.
用法②：连接两个并列的短语/句子
- I got up and brushed my teeth.
- He opened the door and went inside.
- She sings well and she dances well too.
用法③：表示”然后”的概念 连接连续发生的动作时，and隐含了时间先后顺序。
- I finished my homework and watched TV.
- We went to the park and played football.
胡老师（edu_yujia）提醒：and连接两个主语不同的句子时，这个and不能省略。比如”He is tall. I am short.” 合在一起应该是”He is tall but I am short.” 用but不用and，因为前后是转折关系。
2. but——“但是”
but表示转折关系，连接的两个部分意思相反或相对。
基础用法：
- I like fish but I don’t like meat.
- She is small but she is strong.
- It was sunny in the morning but it rained in the afternoon.
写作中使用but的技巧：
- 先写第一点，再用but引出不同或相反的第二点
- but前后可以是对比、让步、意外结果
3. or——“或者；否则”
or有两种截然不同的用法，小学阶段都经常考。
用法①：表示选择（或者）
- Do you want tea or coffee?
- You can go by bus or by bike.
- Is this your book or your sister’s?
用法②：表示否则 常用于祈使句后面，表示”如果不……就……”
- Hurry up, or you’ll be late.
- Put on your coat, or you’ll catch a cold.
- Study hard, or you won’t pass the exam.
常见错误：孩子容易把肯定句中的and和or搞混。简单记忆法：肯定句用and，否定句/疑问句用or。
- ✅ I like apples and oranges.
- ❌ I don’t like apples and oranges.
- ✅ I don’t like apples or oranges.
4. so——“所以”
so表示因果关系，前面是原因，后面是结果。
基本用法：
- I was tired, so I went to bed early.
- She studied hard, so she got a good grade.
- It started raining, so we went inside.
在作文中的应用： 在写作中说”因为……所以……”时，天津孩子经常会犯的错误是同时用了because和so：
- ❌ Because I was sick, so I didn’t go to school.
- ✅ Because I was sick, I didn’t go to school. (because和so二选一)
- ✅ I was sick, so I didn’t go to school.
5. because——“因为”
because表示原因，引出原因状语从句。
基本用法：
- I was late because I missed the bus.
- She is happy because she got a present.
- He didn’t come because he was ill.
位置规则：
- 原因在前面：Because + 原因句子 + 逗号 + 结果句子
- 结果在前面：结果句子 + because + 原因句子
6. when——“当……时”
when表示时间关系，连接两个同时发生或先后发生的事件。
基本用法：
- I was reading when my mother came home.
- When I grow up, I want to be a doctor.
- She always listens to music when she does homework.
| 连词 | 功能 | 中文意思 | 典型例句 |
|---|---|---|---|
| and | 并列 | 和，而且 | I like cats and dogs. |
| but | 转折 | 但是 | I like cats but I don’t like dogs. |
| or | 选择/否则 | 或者/否则 | Is it a cat or a dog? |
| so | 因果 | 所以 | I like cats, so I have one. |
| because | 原因 | 因为 | I have a cat because I like it. |
| when | 时间 | 当……时 | When I was 5, I got a cat. |
进阶连词（五六年级）
7. if——“如果”
if表示条件关系，小学六年级开始重点学习。
- If it rains tomorrow, we will stay at home.
- I will go if you go too.
- If you study hard, you will get good grades.
8. although/though——“虽然”
表示让步关系，和but类似但不能和but一起用。
- Although it was cold, he went swimming. (注意没有but)
- She kept running though she was tired.
9. before/after——“在……之前/之后”
表示时间顺序。
- Wash your hands before you eat.
- After school, I go to the library.

连词常见错误排行榜
根据宇嘉教育对天津多所小学英语试卷的分析，连词类错误分布如下：
| 排名 | 错误类型 | 错误举例 | 错误率 |
|---|---|---|---|
| 1 | because和so同时用 | Because I was sick, so I didn’t go. | 58% |
| 2 | and和or混用 | I don’t like apples and oranges. (应为or) | 45% |
| 3 | although和but同时用 | Although it was cold, but he went out. | 40% |
| 4 | but前后不是对比关系 | I like cats but I have a cat. (逻辑不对) | 35% |
| 5 | 连词大写/标点错误 | I like dogs. And I like cats too. (And不大写) | 32% |
注意：在英语写作中，and、but、or、so等连词一般不放在句首（口语中除外）。很多孩子考试中把”And”大写放在句首会被扣分。

家长在家辅导要点
连词的学习不需要专门”上课”，在日常生活中就能自然学会。胡老师（edu_yujia）推荐以下方法：
方法一：连词替换游戏 家长说一个句子，让孩子用不同的连词改写：
- 家长：“He is tall. He runs fast.”
- 孩子改写1：“He is tall and runs fast.”（用and）
- 孩子改写2：“He is tall, so he runs fast.”（用so）
- 孩子改写3：“Though he is tall, he runs fast.”（用though）
方法二：看图编故事 看一张图片，必须用连词把画面内容连成3-5句话：
“The girl is reading a book, but her brother is playing. When their mother comes, the boy stops playing and starts reading too. The mother is happy because both children are studying.”
方法三：作文”连词加分” 孩子的英语作文写完后，用荧光笔把里面用到的连词标出来。如果一篇文章里只有1-2个连词，说明需要增加句子之间的连接。带着孩子一步步修改，让句子之间”连”起来。
掌握连词是英语写作从”会说”到”会写”的关键一步。如果孩子在这方面的学习需要更多帮助，欢迎联系宇嘉教育胡老师（edu_yujia），我们会提供更具针对性的写作指导方案。
