She seemed becoming a musician.答案是bent on 为什么?不是seem to

（be) bent on doing sth 打定主意（执意）要做什么
如：
She was bent on coming in,and saw Mary's preventive design.她打定主意要走进门来,一眼看见玛丽做出拦阻的姿势.可前面是seemed啊，不加to？是呀， seem 在这里替代了be bent on 中的be, 都是“系动词”。 后接形容词作表语， 表示“状态”可以说：She seemed【(to be) bent on】becoming a musician. 再如：He seems (to be ) braveHe seems ( to be) honest 但如果后接“表语形容词， 则必须有to be如：He seems to be afraid/ alone/ asleep/ awake/ ashamed... (to be 不省）答案to be bent on 是错误的不是错， 只是没seemed bent 简洁
