为什么"And"、"But"和"So"不够用
你已经掌握了基础：and 、but 、so 、because。在简短回答中，它们还可以，但在 DET 答题任务中，使用这些连接词会很快变得重复------并且向评分者表明你的水平较低。
在 Upper Intermediate 级别（DET 110--125），你的任务不仅仅是连接想法，而是要精确地连接它们。每种想法之间的逻辑关系都有其自己的过渡短语。使用正确的短语可以表明清晰的思路和强大的连贯性。
本讲座为你提供一个包含五个类别的工具包。每个类别包含两到三个短语，你可以立即开始在 Speak About the Photo 、Read Then Speak 、Interactive Speaking 和 Speaking Sample 任务中使用。
您的五种过渡句型工具箱
1. Addition --- 增加一个相关的想法
用法：On top of that... / What's more... / In addition to that...
❌ 弱： "She works long hours and she doesn't take breaks."
✅ 强： "She works long hours. ++On top of that++, she rarely takes breaks --- so fatigue becomes a real issue."
2. Cause --- 解释某事发生的原因
用法：This is largely because... / One reason for this is... / Part of the reason is...
❌ 弱： "People move to cities because jobs."
✅ 强： "People move to cities. ++One reason for this is++ that job opportunities are much more concentrated in urban areas."
3. Result --- 展示因果关系的结果
用法：As a result... / This means that... / Because of this...
❌ 弱： "He didn't sleep well so he was tired."
✅ 强： "He didn't sleep well. ++As a result++, his concentration dropped significantly throughout the day."
4. Contrast --- 展示差异（而非反驳论点）
用法：That said... / At the same time... / Even so...
❌ 弱： "It's expensive but people buy it."
✅ 强： "The product is quite expensive. ++That said++, many people still choose it because of the quality."
5. Examples --- 用具体事物来支撑您的观点
用法：For instance... / To give a specific example... / Take X as an example...
❌ 弱： "Technology helps students. For example, phones."
✅ 强： "Technology helps students stay organized. ++To give a specific example++, many students use apps to track deadlines and review notes on the go."
如何在实际的 DET 任务中使用这些
在 Interactive Speaking 中，您每轮有 35 秒，没有准备时间。您无法计划好每一句话 --- 但您可以练习用每个想法的一个过渡性短语来固定您的发言。一次自然的发言听起来是这样的：
"I think remote work is very effective for focused tasks. ++This is largely because++ there are fewer interruptions than in an open office. ++For instance++ , many people find they finish reports faster at home. ++That said++, team collaboration can be harder, which is worth thinking about."
请注意：四个想法，四个过渡，零个 "and" 或 "but" 的重复。这就是您要努力达到的标准。
在 Speaking Sample（30 秒准备 / 3 分钟发言）中，您有更多时间进行计划。利用您的准备时间，在心里为计划涵盖的每个想法分配一个过渡性短语。这可以防止思路跳跃，并使您的回答在考官听来有条理且流利。
要避免的常见错误：
-
不要堆叠过渡词：❌ "And also, on top of that, furthermore..." --- 一个精确的短语胜过三个模糊的短语。
-
在非正式的口语环境中不要使用 "however" 来表示对比 --- 它听起来过于正式。请改用 "that said" 或 "even so"。
-
不要说 "for example" 然后不给出实际例子 --- 确保后面总有一个具体的细节。
