  I assess the extent to which the recently introduced BERT model captures
English syntactic phenomena, using (1) naturally-occurring subject-verb
agreement stimuli; (2) "coloreless green ideas" subject-verb agreement stimuli,
in which content words in natural sentences are randomly replaced with words
sharing the same part-of-speech and inflection; and (3) manually crafted
stimuli for subject-verb agreement and reflexive anaphora phenomena. The BERT
model performs remarkably well on all cases.
