26.Historians such as Le Roy Ladurie have used the documents toextract case histories， which have illuminated the attitudes ofdifferent social groups (these attitudes include，but are not confinedto，attitudes toward crime and the law)and have revealed how theauthorities administered justice. 7 J; {/ v' v( d, h4 u 象勒罗伊·拉迪里(Le Roy Ladurie)一类的史学家利用这些文献史料从中挖掘出某些个案史(case history)来，阐明了不同社会群体的态度(这些态度包括，但并非局限于，对犯罪和法律的态度)，并揭示出当局是如何执行审判的。 $ x9 a/ F& A1 x9 U: h# K27.One such novel idea is that of inserting into the chromosomesof plants discrete genes that are not a part of the plants’ naturalconstitution：specifically，the idea of inserting into nonleguminousplants the genes，if they can be identified and isolated，that fit theleguminous plants to be hosts for nitrogen-fixing bacteria.
