VOA慢速英语:President Obama Nominates Elena Kagan to Supreme Court

1.If confirmed by the Senate, the fifty-year-old Kagan would be the youngest justice on the current Supreme Court.

If省略句：if+过去分词的省略形式：

其中的过去分词可视为是被省略的被动结构，即在if与形容词之间省略了主语和助动词be。如：

例句：He will come if asked.= He will come if he is asked.
      他如被邀就会来。

      The medicine is quite effective if taken in time.=The medicine is quite effective if it is taken in time. 这
      药要是能按时服用，效果是很好的。

还有另外一种省略形式：

if + 形容词

这类结构通常可视为在if与形容词之间省略了“主语+动词be的适当形式”。如：

Send the goods now if ready.= Send the goods now if they are ready. 货物如已备好，请即送来。

If true, this will cause us a lot of trouble.= If it is true, this will cause us a lot of trouble. 这事若是事实，它将给我们造成许多麻烦。

注：这类省略结构中有的已构成相对固定的搭配，if necessary (如果需要)，if possible (如果可能)等。如：

If necessary, ring me at home. 如果必要，可往我家里打电话。

If possible, let me know beforehand. 如果可能，可在事前通知我。

2.She briefly barred military recruiters from using law school facilities.

bar from禁止(接近〔做〕…)

例句：The members voted to bar women from the club.
      会员表决不让妇女加入该俱乐部。

      After the member was caught cheating, he was barred from the club.
      那会员行骗被抓后, 被开除会籍。

3.However, President Obama and Democrats in the Senate hope to have Elena Kagan confirmed in the next few months.

have Elena Kagan confirmed是宾语和宾语补足语的机构

①have sb／sth do sth．与have sb／sth doing sth．两者都是宾语发出的主动动作。前者指 “使某人／物做某事（指一次性的具体的动作）”；后者指“使某人／物一直处于某种状态”，常接一段时间作状语。②have sth．done这一结构中的宾语与宾补动词是被动关系。③have sth． to do这一结构中的have意为“有”，即“有某事要做”。
