Despite the demise of TESOL's Essential Teacher magazine, where Richard Firsten used to ply his trade, TESOL has found his goofy grammar guidance so indispensable that they continue to promulgate it through the web-based TESOL Connections. This time around, though, he gets it mostly right.
I wouldn't call We’d rather he didn’t, "the present subjunctive" as he does, and as I've said before, I think he's wrong that the we in we teachers is a pronoun. But these are mostly terminological matters. Generally, the answers make sense. If he plans to keep up this schtick, then let's hope he continues in this vein.
