superfluous 【superfluous】adj.多余的We have enough food for the picnic; any more food would be superfluous.我们有足够的野餐食物，再多的食物将会是多余的。

Accepted Answer

[suː'pɜːrfluəs] 
superfluousmore than is needed, desired, or required
When something is so unnecessary that it could easily be done away with, like a fifth wheel on a car or a fifth person on a double date, call it superfluous.
Superfluous (soo-PER-floo-uhs) means "more than required." Use it when pointing out something that could be removed without detracting from the quality of something: "For a climb over a glacier, the very thickest shoes are absolutely necessary; beyond these, all else seems superfluous to me," wrote the adventurer Charles Stoddard in 1899. The word comes from Latin and literally means "overflowing": super, "over" + fluere, "to flow." So you can think of a superfluous addition as flowing over the boundaries of what's needed.
