英語常用語法：句子轉折詞的橋樑“They are wasting resources, for example, time, energy and money.”
上面這句話不錯，只是轉折詞“for example”不妥當;應該這樣：
“They are wasting resources. For example, they use too much time, energy and money.”
不然就要換一換轉折詞，改用“such as”或“like”：
“They are wasting resources, such as (or like) time, energy and money.”
不管任何語言，轉折詞(transitional words)都扮演着一個重要角色，就是：承先啓後，使句子緊湊，段落相吸，對文章結構，有良性作用。但是有些人幾乎沒有採用轉折詞的習慣，結果文句鬆散，上下文七零八亂，應該避免。
現在把主要轉折詞，分類列下，供大家參考。
