这套练习有十道原创题，由易到难排列，混合了段落衔接的五项技能：代词指代、连接词、主题句、段落间重复和视角转换。
每题先写出自己的答案，再打开解析。
这些题没有标准分数，请用一个标准评价自己：只看这页文字的读者，能不能看懂句子之间的联系？很多题有不止一个好答案，所以比较的是推理过程，而不是一字不差的措辞。写作修改对比视图和错题记录与重测队列可以用来记录你的发现。
题目
1. 重写句子，使代词清楚：“Dina told Mei that she had left her bag on the bus.”
Show answer
“She”和“her”都可能指 Dina 或 Mei。先决定，再写明：“Dina told Mei, ‘I left my bag on the bus.’” 或 “Dina told Mei that Mei had left her bag on the bus.” 改用直接引语是消除歧义的一个干净办法。
2. 为空格选一个连接词：“The shop ran out of stock by noon. ______ it closed early.”
Show answer
提早关门是因为货卖完了，所以是因果关系：“As a result,” 或 “Consequently,”。用 However 会错误地暗示转折。
3. 对于题目 “Explain why young people should learn to cook”，哪个开头句更紧扣题目？ (a) Kitchens come in many shapes and sizes. (b) Cooking teaches young people to look after themselves before they leave home.
Show answer
**(b)。**它给出回答问题的理由，并用到题目的关键概念（young people、cooking）。句子 (a) 是事实，但与题目无关。
4. 找出转换并修改：“When a driver is tired, you should stop and rest.”
Show answer
它从 “a driver” 转到了 “you”。修改：“When a driver is tired, he or she should stop and rest.” 或 “When drivers are tired, they should stop and rest.” 第二种写法避免了生硬的 “he or she”。
5. 哪里不清楚？“The teacher gave the students a worksheet and a book, and they found it useful.”
Show answer
“It”可能指练习纸、书，或两者，而“they”也可能被读得含糊。先决定到底什么有用：“The students found the worksheet useful.” 如果两样都有用，就写 “found both useful”。
6. 改正时态转换：“Last Sunday we visited the old fort. Our guide tells us that it was built long ago, and we listen carefully.”
Show answer
故事发生在过去，但 “tells” 和 “listen” 是现在时。修改：“Our guide told us that it had been built long ago, and we listened carefully.” 注意 “was built” 变成了 “had been built”，因为建造发生在导游说话之前。
7. 一篇关于骑单车上学的文章中相邻的两段。Paragraph A 结尾：“Cycling therefore keeps students fit.” Paragraph B 开头：“Students who cycle also stay healthy, since the exercise is good for the body.” 问题在哪里？怎样修改 B 的开头？
Show answer
Paragraph B 重复了 A 的想法（健身和健康是同一个要点），而 “also” 还暗示有新内容。给 B 一个新任务，例如费用或时间：“Cycling also saves families money, because there is no bus fare or fuel to pay for.” 现在它加入了一条新的理由。
8. 每一对句子都需要一个连接词。说出关系并选择连接词。 (a) “Amin studied very little. ______ he passed easily.” (b) “The museum is open on weekdays. ______ it closes on public holidays.”
Show answer
(a) 结果与预期相反，所以是转折：“Even so,” 或 “However,”。(b) 第二句限制了第一句，同样是转折或例外：“However,” 或 “But it”。(a) 常见的错误答案是 “Therefore”，它暗示读书少导致了通过。
9. 这一段有三处错误。找出并修改。
A good neighbour keeps the noise down. You should also greet people politely. One can tell that they are happy to live there. It is nice when someone does this.
Show answer
错误：(1) 视角从 “a good neighbour” 转到 “you” 再转到 “one”；(2) “they” 不清楚，可能指邻居，也可能指被问候的人；(3) 最后一句的 “this” 没有明确对象。一种修改：“A good neighbour keeps the noise down and greets people politely. Such a neighbour makes the people nearby happy to live there. That courtesy costs nothing and is always noticed.” 每处修改都保持了单一视角，并在 “that” 后面写出了名词。
10. 以下是一篇主张每所学校都应设有菜园的文章中四个段落的主题句。哪一句跑题了？你会怎么处理？(1) A garden teaches students where food comes from. (2) Working outdoors gives students a break from screens. (3) The canteen menu has changed many times this year. (4) Shared tasks in the garden build teamwork between classes.
Show answer
句子 3 跑题了：它讲的是食堂菜单，没有给出设菜园的理由。可以删掉这一段，或给它建立联系，例如 “Growing vegetables on site could give the canteen fresher ingredients for its menu.” 其余三句各给出一个独立的好处，这正是这篇文章的主题句应该做的。
如果你答错了
根据你的错误类型，选择要回头复习的课。
| 如果你错在 | 回到 |
|---|---|
| 第 1、5 题，以及第 9 题中的 “this” 或 “they” | 让代词指代清楚 |
| 第 2、8 题 | 用能表达真实关系的连接词 |
| 第 3、10 题 | 让主题句紧扣题目 |
| 第 7 题 | 删除相邻段落之间的重复 |
| 第 4、6 题，以及第 9 题中的视角错误 | 修复突然的视角转换 |
批改自己时，除了题号，也要记下错误的类型。如果同一类型出现两次，那就是接下来该练的技能。
这套题做得顺手后，可以继续学习句子掌控。如果你想要有人检查你自己写的段落，而不只是这里的例子，这就是一对一线上 English First Language 补习的用处。
