I don’think it advisable that Tom be assigned to...
例句中Tom 后面的be动词为什么是原型,不应该是is吗?
it为形式宾语,that从句为真正宾语从句。形容词advisable为宾补。形容词作宾补,宾语和宾补之间为主系表关系,即:
It is advisable that...
动词advise,及其同源名词advice、同源形容词advisable均表示建议、忠告之意,与其有关的that从句(主语从句、宾语从句、同位语从句)均需要用虚拟语气,表示非事实。谓语用动词原型或should do。

在 advisable, appropriate, desirable, essential,fitting, imperative, important, impossible, necessary, obligatory, proper 等形容词后面的 that 从句中,谓语动词应该用动词原形或者 should + 动词原形:前者常见于美式英语中,后者是英式英语。例如:
I think it advisable (明智的) that an armed guard stand in readiness. (摘自章振邦主编:《新编高级英语语法》p.166)
在英式英语中,上述that 从句中,谓语动词也可以用动词的陈述式表示。例如:(以下例句摘自章振邦主编:《新编高级英语语法》p.166)
It is essential / imperative / obligatory / proper that he have all the facts.(美式英语)
It is essential / imperative / obligatory / proper that he should have all the facts.(英式英语)
It is essential / imperative / obligatory / proper that he has all the facts.(英式英语)
