sigh[sai]v.,n.叹息，叹气 etc
sight[sait]n.视力，情景 etc
sign[sain]n.告示，迹象，符号 ，签名 etc
g在这三个中都不发音 因为
1.字母组合“gh”不发音，如
eight—ate, might—mite, sight—site—cite, sought—sort, straight—strait,bought—bort, slight—sleight, through—threw, bough—bow, sleigh—slay, weigh—way—whey, aweigh—away, high—hi—hie, weight—wait ,etc
2. “n” 前的“g”常常为无声字母,如
reign—rein, gnaw—nor, sign—sine, feign—fain—fane, gneiss—nice,etc本回答被提问者采纳
