多余的怎么用英语怎么说

"Extra" is the English word that means "surplus" or "unnecessary." It comes from the Latin word "extremus," which means "beyond" or "outside."
Here are some examples of how "extra" can be used in English sentences:
"I have an extra pair of shoes in my closet if you need them." (我衣柜里有一双多余的鞋子，如果你需要的话。)
"We have an extra room in our house that we don't use. Do you want to rent it?" (我们家里有一间多余的房间没人住，你想租吗？)
"I ordered an extra side of fries because I was really hungry." (我额外点了一份薯条，因为我真的很饿。)
You can also use "extra" as an adjective to describe something that is more than what is needed or expected:
"I have an extra blanket on my bed in case it gets cold tonight." (我床上有一条多余的毛毯，以防今晚变冷。)
"The store is offering an extra 10% off all items this weekend." (这家商店本周末所有商品都有额外的 9 折优惠。)
