Question

impenetrable adj.不能穿过的；不可理喻的 (1) 装甲板普通子弹打不穿。(2) 有些野雉喜欢生活在密密的丛林里。(3) 那起罪行的作案动机叫人捉摸不透。(4) 这本历史书我完全看不懂. Impenetrable comes from the Latin impenetrabilis, meaning "not to put or get into, enter into." Impenetrable, the adjective, has two meanings. When you're trying to learn a subject that is so complicated, so confusing or so detailed that it seems like it's in another language or from another planet, it's impenetrable — like calculus. Or a physical object can be impenetrable, meaning it is impossible to actually enter or get inside of, like that impenetrable nightclub that has bouncers watching every entrance to keep you and your friends out.
