機器在推
最字面的一支：真的有一台機器，前面真的有土或房子。後面所有用法借的就是這裡的畫面。
verb · B2
To push earth, rocks, snow, or rubbish out of the way with a bulldozer, often shoving it all into one big pile.
推開（土石等）
核心畫面
One picture carries the whole word: a wide flat blade moving forward low to the ground. It does not lift, it does not pick things apart, and it does not stop to look. Whatever is in front of it gives way. If what is in front is loose earth, the earth moves. If it is a house, the house comes down. If it is a crowd, people are pushed aside. If it is a person's decision, or an idea somebody just offered, that gives way too. So the question the word always answers is the same one: what was in front of the blade?

可以想成一塊又寬又平的鏟板，貼著地面往前推。它不會抬起來，不會一塊一塊拆，也不會停下來看一眼。擋在前面的東西就是得讓路。前面如果是鬆土，土就移位；如果是房子，房子就倒；如果是人群，人就被撞開；如果是某個人的決定，或是別人剛講出口的想法，那也一樣被推平。所以每次遇到這個字，你只要問同一個問題：這一次擋在鏟板前面的是什麼？From the word’s history
From an earlier word bulldose, literally a bull-dose, a dose fit for a bull: a force far bigger than the thing it is aimed at. The machine was named from the word, not the other way round.
來自更早的 bulldose：bull（公牛）加 dose（一劑），字面是「給公牛的一劑」——遠遠超過需要的力道。也就是說，這個字先有，推土機 bulldozer 才是照著它命名的。

Three branches
人自己就是那塊鏟板
機器退場，換成一個人的身體或氣勢往前。擋在前面的從土石變成人群、後衛，或一個還沒準備好的房間。
verb · C1
To move forward with so much force that people and things are pushed aside or knocked over, and to get past whatever is in your way without slowing down.
硬闖；橫衝直撞
把別人的意願或點子壓平
鏟板前面的東西變成看不見的：對方本來的猶豫，或是剛講出口的提議。壓過去的方式也從力氣換成壓力和速度。
verb · C1
To force someone into doing something they do not really want to do, by pushing so hard and so fast that they never get the chance to stop and think.
硬逼某人做某事
