新東方酷學酷玩夏令營介紹在英語學習中英語作文中常用的連接詞。
    “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）都扮演著一個重要角色，就是：承先啟后，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采用轉折詞的習慣，結果文句松散，上下文七零八亂，應該避免。
    現(xiàn)在把主要轉折詞，分類列下，供大家參考。
