请各位英文好的,帮我看看这几个句子有什么错误,

(a) I was given a little lovely vase,去掉little,vase 是可数名词,如果后面是vases,可以把little 改成 few.
B,这个句子没有写完吧,不是完整的.
C.固定搭配,give sth to Sb.因此要加一个to.Peter gave a box of chocolates to his girlfriend.
(d) We sent Mary them,them 改成there,如果是them,句子是不通的,改成there,意思是我们送Mary 到那里.
(h) The south is the beautifulest region in my country.形容词的*根据音节而定,如果是多音节的（指的是三个音节以上的,就加most）,正常的就加est.如beautiful是三个音节,变*就是the most beautiful.因此 beautifulest 改成 beautiful,前面加most.
(i) I like people they are helpful.they 改成who.意思是我喜欢乐于助人的人.people 后面的成分这里是要做定语从句的,要用who来引导.they不能.
(j) She musts come to the party.musts 改成must,情态动词 没有人称和数的变化的.
