1. In 1913, his father [. . .] had Otto committed to a psychiatric clinic, on the grounds that his belief in free love proved his insanity.
1913年，奥托的父亲把奥托送进了精神病诊疗所，理由是奥托主张自由恋爱，足见是真疯。
注意：①his如果译作“他的”，在整句译文里指代关系不明的话，干脆多写“奥托的”。愚见是英语的代词用得比汉语频繁，何况his与her读音、写法都不同，而“他的”、“她的”（还有“它的”）汉语读起来一样，容易混淆。②on the grounds that与because的区别。

2. Kafka took a close interest in education.
卡夫卡对教育兴趣很浓。
注意：interest表示“兴趣”，到底可数不可数？

3. emphasize and elucidate the view that parents were the last people to be entrusted with bringing up their children
强调并阐释这一观点，即绝不该让父母抚养亲生子女
注意：①elucidate、expound与explain的区别。②last的用法。③entrust后接with。

4. project their view onto the child
自认为孩子与自己看法一致
注意：即便要把project译作“投射”，也要明白这比喻义的“投射”到底是什么意思。project作动词与作名词时，读音不同。

5. the motive of concupiscence
淫欲饥渴的驱动
注意：①lust与sexual desire之外，还有重音在-cu-的concupiscence——里面藏着Cupid，发现没？②区别motive与motivation。
