這四個單詞是中考英語當中常出現的考點。也是我們同學容易混淆的內容，許多同學不能準確的區分它們的用法。現在我們來做一個簡單的區分。
一、使用pay時是人做主語，可以與for搭配。例如:
I paid ten dollars for the coat.
How much do I have to pay you for it？
She She paid me ten yuan for the T shirt。
二、使用spend時也是人做主語。常與介詞on搭配。例如，
I spent one hundred yuan on the dictionary
She has to spend a lot of money on
downloading information from the Internet！
spend還表示花時間，常與介詞in搭配，in可以省略，後接動名詞。例如，
I spend around three hours（in) learning English every day！
How will you spend your holiday?
三、只用來表示花時間，而且主語必須是it，形成:It takes/took sb.+時間段名詞+to do sth.結構。例如，
It takes me twenty minutes to get home from my school.
It took them two months to finish all the work.
四、cost表示某物花某人多少錢。主語是事物，不是人。
The computer cost me more than three thousand yuan.
How much did the watch cost you?
總得來說，花錢用pay，spend和cost，花時間用spend和take，但要注意主語是人還是物。
