请分析下面句子的结构说出各个成分?

1）I have two elder sisters。主语：I；谓语：have；宾语：two elder sisters。" elder "是修饰宾语的定语2) They don't swim very well。主语：they ；谓语：don't swim。因为swim是不及物动词,没有宾语。Very well是补语,表示游得怎样。3) Do you go to school every day?（你每天去上学吗?）主语：you; 谓语：Do…go,这边表示普通疑问句,do提前。to school目的状语；every day是时间状语。4) I really want a cup of tea。（我真的想要一杯茶。）主语：I；谓语：want；宾语：a cup of tea。really是副词,谓语的状语。5) Miss Smith teaches English very well。（史密斯先生教英语非常好。）主语：Miss Smith；谓语：teaches；宾语：English；very well同样是补语。
