VOA慢速英语:Donors Promise $12 Billion to Fight AIDS, TB and Malaria

1.It's important to know that we'll not be cutting funding to any of our existing programs and those programs will continue over the next few years to put more people on treatment, to have more prevention efforts, more care efforts as well.

这句话的真正主语是后面的不定式，it是形式主语。to put，to have表示目的。

2.Given the difficult economic climates and fiscal pressures that a number of donors are under, we achieved a significant increase over the last replenishment which was three years ago.

Given考虑到

Given还可以引导条件句

given与provided意思一样,表示“如果有……,则……”,
但两者的区别是provided后面只能跟that引导从句,而不能跟名词或名词性短语。而given后既可跟从句,又可跟名词性短语。

3.Still, the pledges were a billion dollars below the lowest estimate of the amount needed to fight the diseases effectively.

Still用法

 still作为连词时含有“尽管如此，可还是要”、“然而”、“不过”之意。例句：

     (1) Although we are very tired, still we shall work. 虽然我们很累，但我们还将工作。

     (2) She was thirsty, still she wouldn't drink. 她虽然渴了，但仍不喝东西。

     (3) I like cats; still I don't care to own one. 我虽然喜欢猫，但不愿意养猫。

     (4) This is a very unpleasant affair. Still, we can't change it. 这是件很不愉快的事，但是我们无法改变它。     此外，still可以与more连用，相当于much more，常译“至于……更不必说”。例句：

     She can speak English, still more Japanese. 她连英语都会说，日语更不在话下。

needed to fight是过去分词做后置定语，修饰amount。
