求both在句中的摆放位置,是在其他副词前还是后,在be动词前还是后?
在行为动词前还是后?等等,
oth的位置可以根据它的语法功能分为:
1 both of the pl 是一个名词性质的短语.作主语是在谓语之前,作宾语时在动词之后.如:Both of the writers were born in Chang an.He picked up both of the passegers from the airport.
of the pl 可以变为:of us/ them/you.也可以省略为:both
2 both (the) pl 中both相当于形容词,作定语,放在名词之前.如:both the brothers,both arms.
3 在名词或代词复数后作主语的同位语用,
1)没有助动词时,就放在谓语之前.如:They both work for the foreign company.The actresses both got into the lift.
2)有助动词时,通常就放在第一个助动词之后.如:They have both kept the secret.The managers are both in faour of the policy.
3)有助动词,但助动词后再没有其它词语时,就放在助动词之前.如:How silly you both are!Have they seen the movie?Yes,they both have.
4)作宾语的同位语时,放在宾语之后.如:I took photographs of them both.
4 both ...and ...是一个连词,用来连接并列的成分.如:She is both glad and sorry to see him.Both John and Jack were criticized by the boss.She was ashamed ,both for herself and for her sister.
