求英语语法达人,帮忙看下我分析的三个句子语法对不对啊
And I believe it has a positive effect on the  creative  capacities of New Yorkers—for creation is (in part merely) the business of forgoing the great and small distractions.                                             语法分析： it后面的整个句子作主句I believe 的宾语从句.      on the  creative  capacities of New Yorker 作effect的宾语补足语.for creation …… 作前面句子的原因状语.(in part merely) —插入语.of forgoing the great and small distractions作business的定语.
•Many people who have no real independence of spirit depend on the city’s tremendous variety and source of excitement for spiritual sustenance and maintenance of morle.                                            •语法分析：      Many people ——主语,depend on ——谓语,the city’s ……excitement ——宾语.who have ……spirit,是who 引导的定语从句.第一个and连接两个宾语同位语,for后面是and连接的两个目的状语.
•I think that although many persons are here from some excess of spirit (which caused them to break away from their small towm),some,too,are here from a deficiency of spirit,who find in New York a protection,or an easy substitution.                                                                                                        •语法分析：      that引导的宾语从句中,many persons are here 是主干成分,from some excess of spirit —原因状语,(which …… towm)—定语从句,修饰many persons.some,too— 插入语,后面跟的是并列句,who引导的定从句,修饰省略的主语many persons .
