在商业和日常生活中，我们经常需要描述物品或服务的价格变化。那么“涨价”和“降价”用英文怎么说呢？
如果你是卖家，你是价格的决定者，你可以说：
涨价
increase the price降价
decrease the pricereduce the priceThe coffee shop is going to increase the price of their cappuccino next week. 这家咖啡店下周将提高卡布奇诺的价格。 The bookstore is reducing the price of all their books by 20%. 这家书店正在将所有书籍的价格降低20%。
如果你不是卖家，看到这个价格涨了或跌了，你可以说：
涨价
the price rosethe price went upthe price increased降价
the price fellthe price went downthe price droppedI wanted to buy a new smartphone, but the price rose by $100, so I couldn’t afford it. 我想买一部新手机，但价格涨了100美元，所以我负担不起。 The airline company announced that the price of their tickets dropped by 30% due to low demand. 这家航空公司宣布由于需求不高，他们的机票价格下降了30%。
像 went up 这种词组动词比一个单词的动词更口语化些。所以我们在口语中平时都会说什么东西 went up， 会比 increased 用得多。
口语中，什么东西涨价或降价了，也可以说 went up/down in price。
我买了这个包后，它涨价了。 The bag went up in price after I bought it.The price of the bag went up after I bought it.
