看美剧学英语习语：Bite the bullet

Fannie

Bite the bullet: To do or accept something unpleasant, often after a period of hesitation;  to accept something difficult and try to live with it.The phrase is thought to have come from the military, perhaps because biting a bullet was a common practice for patients, due to a lack of anesthesia(麻醉). As in I know it is really tough，but you have to bite the bullet and try your best to get it done.

中文释义：“bullet” (n.) 意为「子弹」；“bite the bullet”按字面意思来理解意为「咬住子弹」。这个习语起源于过去的战地手术：受伤的士兵们在接受手术时没有被麻醉，他们会咬住一颗子弹，以分散注意力和减少喊叫，而且这个子弹还必须是铅作的。因为铅比较软，伤员的牙齿不会受伤。因此，这个习语真正的含义是「咬紧牙关应付、硬着头皮做不愉快的事」。例句：At this point, I either give up and admit defeat, or bite the bullet.（到这个时候了，我要么放弃，承认失败，要么咬紧牙关去面对。）
