5.16 判断题：判断下面陈述的正误。<br>                                          
&nbsp;&nbsp;&nbsp;&nbsp; (a)                                     
语法制导定义中某文法符号的一个属性，既可以是综合属性，又可以是继承属性。<br>     
&nbsp;&nbsp;&nbsp;&nbsp; (b) 只使用综合属性的语法制导定义称为S-属性定义。<br>                                        
&nbsp;&nbsp;&nbsp;&nbsp; (c)                                   
把L-属性定义变换成翻译模式，在构造翻译程序的过程中前进了一大步。<br>     
&nbsp;&nbsp;&nbsp;&nbsp; (d)                                  
翻译模式既适于自顶向下分析，又适于自底向上分析。<br>     
&nbsp;&nbsp;&nbsp;&nbsp; (e)                                 
用于自顶向下分析的翻译模式，其基础文法中不能含有左递归。<br>     
&nbsp;&nbsp;&nbsp;&nbsp; (f)                                
在基础文法中增加标记非终结符不会导致新的语法分析冲突。
