1.neither
['ni:e?]
adj.(两者)都不的
pron.两者都不
adv.也不
conj.不
eg：I went to see Jack and Bill yesterday, but neither one was at home.
昨天我去看杰克和比尔, 可是两个人都不在家.
2.either
['aie?]
pron.(两者之中)任何一个
adj.(两者中)任一的
adv.(否定句中)也
adj.非此即彼的, 两者择一的
eg：【1】I don't think either of them are at home.
我想他们中任何一个都不在家.
【2】I have bought two books, you can have either.
我买了两本书, 你要哪一本都可以.
总的来说either更强调“任一”,但neither强调“两者都不”
而且either在否定句句末表示“也”的意思,neither一般不会出现在句末的
eg：【1】The product is of high quality and is not expensive either.
这种产品质量好价格也不贵.
【2】He won't go and I won't go either.
他不去, 我也不去.
好,就是这样.不知帮到你没?
