　　AndhehadbeenanagnosticforaslongasIcouldremenber(alwaysagitatedandaghastwheninthepresenceofareligion'spurveyor).Yet,hewasanagreeableman.Itwasjustthechoicehewassoagogovereventually,leftmewithmymouthagapewhenhetoldmeofit:tobeafarmer,tomasterallthingsagrarian.Hehadanagilemind;hedidn'taggrandisehisdecision,didn'tmakemuchofitotherthantoaffirmthehapinessinthechoicehehadnoaffinityforupuntilthen.

　　在句子Hehadanagilemind;hedidn'taggrandisehisdecision,didn'tmakemuchofitotherthantoaffirmthehapinessinthechoicehehadnoaffinityforupuntilthen.
