five hundred dollars a month is enough to live(自動詞後要加介詞) on  

betide what may , we will not despair , were the world never sounfriendly . 

問題：

這句是出自cnn的廣播新聞,不懂翻譯,有點(diǎn)亂.

同是出自cnn 的新聞,這里的blame 是被動的,還是作主動用法,求翻譯.

 committed 為什么是被動?而its mission 的動詞又是什么?

give matter its mass  這一句到底是怎么的一個(gè)用法?

為甚說是moment’s notice? in (為什么有這個(gè)介詞?)what ought to be（這個(gè)的意思是?）

 求這句的意思和解釋這樣的用法,為甚late前可以加of?

live 后面不加on 行么? 為什么自動詞后一定要加介詞?不加的又是什么情況,有例子嗎?

 were the world never so unfriendly .= 即使世界不再友善 ,這里有連個(gè)否定,不就是友善么,為什么還說不再友善呢?
