很簡單：
1 是看動詞,不同的動詞的用法不同,很多是接雙賓語,很多卻接復(fù)合賓語.
以下為復(fù)合賓語結(jié)構(gòu)：
ask sb.to do sth.
tell sb. to do sth.
teach sb to do sth .
order sb. to do sth.
get sb. to do sth.
know sb. (to) do sth.
advise sb. to do sth.
recommend sb. to do sth.
help/make/let/have/see/feel/find/hear/watch/notice/listen to/look at/note/perceive/behold/observe sb. do sth.(這些都是省略不定式to的復(fù)合賓語結(jié)構(gòu))
以下都是雙賓語結(jié)構(gòu)：
帶 to 的： bring , fetch , give , hand , leave , lend , offer , owe , pass , pay , post , promise , read , sell , send , show , take , teach , tell , throw , write 等.
帶 for 的 ：book , buy , call , choose , cook , do , fetch , find , get , keep , leave , save 等.
bring/ fetch/ give/ hand/ post/promise/ read/ sell/ send/ show/ take/ teach/ tell sb. sth.
=bring/ fetch/ give/ hand/ post/ promise/ read/ sell/ send/ show/ take/ teach/ tell sth. to sb.
book/ buy / call/ choose /cook/do / fetch/ find /get/keep / leave/save sb. sth.
=book/ buy / call/ choose /cook/do / fetch/ find /get / keep/leave /savesth. for sb.
2 是看句型.
動詞＋間接賓語＋直接賓語＝動詞＋直接賓語＋介詞to/for+間接賓語結(jié)構(gòu)的就是雙賓語結(jié)構(gòu)
動詞＋賓語＋to不定式短語 或者
動詞＋賓語＋形容詞/過去分詞/現(xiàn)在分詞/名詞 或者
動詞＋it(形式賓語)＋形容詞/過去分詞/現(xiàn)在分詞/名詞＋實際賓語（不定式或動名詞短語或者介詞短語等）
結(jié)構(gòu)的就是復(fù)合賓語.
