[請益] be或是is的用法

[klain (klain)]

有一句句子出現在教科書中
A decentralized approach requires that each end system be able to communicate
in a secure manner with all potential partner systems.

我想問的是:
require that後面不就是一個另外句子了嗎?
所以我覺得該是使用require that each end system is able to吧?

推 areca:require跟suggest一樣  that後面的子句其實都省略了should
→ areca:留下一個原形動詞  http://ppt.cc/jtDD有例句
→ klain:請問除了require與suggest這兩動詞之外, 還有其他動詞這樣嗎
推 abby0302:還有insist
