Tom is a handsome boy.这个句子哪个是表语,哪个是定语?系后为表,那a handsome boy整个是表语,还是handsome  是形容词作定语修饰boy,boy  是表语?2.Russia has lately decided to expel a US  diplomat from its land and  has declared he has done sth improper. 请问这个是什么句型?  并列主语,叫什么句型?

1.a boy 是表语
handsome是定语，修饰boy
2. Russia has lately decided to expel a US diplomat from its land这是主谓宾加宾语补足语
（Russia）has declared （that） he has done sth improper.这是主谓+宾语从句（that省略了）

1 is后的都是表语、、a handsome boy 整个是表语
2 declared    (句子是不是差了that?!!)  后的he has done sth improper.  是一个从句、、、、

• 
  （. Russia）  【 has lately decided 】{to expel a US  diplomat ）from its land}     and          【 has declared】{ he has done sth improper.}
  其实这不是一个很复杂的句子、、不知道我画的成分你看懂没、、就是and链接的两个句子

a handsome boy整个是表语,handsome  是形容词作定语修饰boy并列谓语eg.并列主语：John and Bob are both my brothers.(John and Bob)并列谓语：He drinks and eats a lot.(drinks and eats)就是主语或谓语同时...
