“首付”可以用“down payment”来表示，付首付可以用put或make来表示。需要注意的是，“down payment”是一个可数名词。
e.g. They were going to use the money for a down payment on a house. 他们打算用这笔钱付首付。
说完首付，很多人可能要问了，那“预付款”“定金”用英语该咋说呢？在英语中，可以用“deposit”来表示“预付款；定金”。
e.g. The shop assistant says if I leave £10 as a deposit, they'll keep the dress for me. 店员说如果我交10英镑定金，他们就会把那件裙子给我留着。
