题目

Bad weather prevented him from starting out for Beijing on time等结构分析.
1.Bad weather prevented him from starting out for Beijing on time.Bad weather主语,prevent终止系动词,him表语,from starting out for Beijing on time是介词词组做him的宾语补足语.2.Neither rain or snow keeps the postman from delivering out letters which we so much look forward to receiving.keeps谓语,the postman宾语,from delivering our letter介词短语做表语做postman的宾补.
还有一道3、As a result of all these factors,governments are becoming increasingly dependent on biologists and social scientists for plainning the appropriate programs and putting them into effect.
这道题的讲解是：“介词on后面表示所依赖的对象，是谓语的一部分”我很迷茫，谁帮我具体分析一下啊？

答案

第一个是主谓宾宾补,没有系表结构,你自己都说了后面是宾补,前面him怎么又是表语呢?
第二个是主谓宾宾补,哪有表语啊,就是后面多了个letters的定语从句,但是那个不影响句子成分啊
