英语常用语法：句子转折词的桥梁“They are wasting resources, for example, time, energy and money.”
上面这句话不错，只是转折词“for example”不妥当;应该这样：
“They are wasting resources. For example, they use too much time, energy and money.”
不然就要换一换转折词，改用“such as”或“like”：
“They are wasting resources, such as (or like) time, energy and money.”
不管任何语言，转折词(transitional words)都扮演着一个重要角色，就是：承先启后，使句子紧凑，段落相吸，对文章结构，有良性作用。但是有些人几乎没有采用转折词的习惯，结果文句松散，上下文七零八乱，应该避免。
现在把主要转折词，分类列下，供大家参考。
