a lot 的意思就等于lots of
many/much和a lot of/lots of意思相同，但语气上，many和much没有a lot of那么随便，a lot of又没有lots of那么随便。所以，a lot of / lots of不宜用于谨严的写作，多见于口语；但问句、否定句口头上也多用many和much。
还有一点，a lot是副词，可以修饰动词，而lots of不可以

求音乐之声电影插曲的英文歌词

edelweiss(雪绒花美国电影音乐之声的插曲)
edelweiss, edelweiss
every morning you greet me
small and white, clean and bright
you look happy to meet me

blossom of snow may you bloom and grow
bloom and grow forever

edelweiss, edelweiss
bless my homeland forever
small and white, clean and bright
you look happy to meet me

blossom of snow may you bloom and grow
bloom and grow forever

edelweiss, edelweiss
bless my homeland forever
