1.It's important that everybody in Haiti understand at this very moment one of the largest relief efforts in our recent history is moving towards Haiti.

very在这里是形容词，表示就在此时此刻。

very可修饰形容词和副词的原级或最高级，不修饰比较级。修饰比较级常用much, far, even, rather等。例如:
　　①He plays football very well. 他足球踢得很好。
　　②She is one of the very best teachers in our city.
　　她是我们市里最好的老师之一。
　　③The population of China is much larger than that of America.
　　中国人口比美国人口多得多。

very可用作形容词,有“真正的,正是……的,十足的”等意。例如:
　①You are the very person I want to see. 你正是我要见的人。
　　②I will do it this very afternoon. 我就在今天下午办这件事。
　　③He is a very fool. 他是个十足的傻瓜。

2.Well, we have to do all we can to try and do some of the life-saving work that's necessary with like I said very little infrastructure to be able to do so.

此句为省略句，即在can后省略了动词 do，若把句子补完整应为we have to do all we can to try and do即句中的不定式短语(to try and

do)是用作目的状语的，而不是与情态动词(can)一起构成谓语。请再看类似例句：(could)

(1) They did what they could to comfort her.
他们尽量安慰她。

(2) They did everything they could to save her life.
他们尽一切力量拯救她的性命。

(3) He studies as hard as he could to catch up with his classmates.
他拼命学习以便赶上他的同学。
