用恶化折词的重要脚色
“They are wasting resources， for example， time， energy and money.”
下面这句话不错，只是转折词“for example”不当当；应该如许：
“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.”
不论任何说话，转折词（transitional words）都扮演着一个重要脚色，便是：继往开来，使句子紧凑，段落相吸，对文章构造，有良性感化。
可是有些人几乎没有接纳转折词的习尚，功效词句松散，上下文七零八乱，应该防止。
现在把重要转折词，分类列下，供巨匠参考。
