末尾为元音的英语单词的复数如何发音,如others,是不是因为是元音,所以发[Z]?

对的
名词复数词（-s,-es）发音：
1.在清辅音/t/,/p/,/f/,/k/,/θ/等后读/s/.
如
books/buks/,maps/m?ps/,roofs/ru:fs/,passports/pa:sp?:ts/
2.在浊辅音/n/,/m/,/v/,/l/,/e/等和元音后读/z/.
如buttons/b?tnz/,customers/k?st?z/,bamboos/b?m'bu:z/,stadiums/steidi?mz/,dollars/d?:z/
3.在/t?/,/d?/,/,/s/,/z/后读/iz/.
如churches/t?:iz/,bridges/brid?iz/,matches/m?iz/,brushes/br?iz/,licenses/laisnsiz/,roses/r?uziz/
