　　IN HIS big annual speech to Congress, Barack Obama made several promises: he pledged to raise the minimum wage for those contracted to the federal government, to create a new tax-free savings bond to encourage Americans to save, to work for the closure of the Guantánamo Bay prison, to push immigration reforms and to veto any sanctions that Congress might pass designed to derail his deal with Iran over its nuclear programme.

　　词汇突破：
pledge 承诺
　　veto 否决 ( 注意和vote：投票)
　　sanction 制裁,命令，决定
　　derail 破坏，出轨

　　主干识别：Barack Obama made several promises
　　其他成分：IN HIS big annual speech to Congress 状语
　　he pledged to raise the minimum wage for those contracted to the federal government, to create a new tax-free savings bond to encourage Americans to save, to work for the closure of the Guantánamo Bay prison, to push immigration reforms and to veto any sanctions that Congress might pass designed to derail his deal with Iran over its nuclear programme.
　　冒号引导的从句解释说明前面的promises.
　　从句中的主干： Sb pledged to do
　　其中四个不定式并列：to raise...,to creat...,to work for...,to push...,to veto...

　　难点解析：其中sanctions被that Congress might pass 和designed to derail his deal with Iran over its nuclear programme所修饰;其中over its programme又在修饰deal;over这个介词可以翻译为：关于也可以翻译为解决;
　　to veto any sanctions that Congress might pass designed to derail his deal with Iran over its nuclear programme.
　　直接翻译出来就是：他会反对，议会有可能通过的， 设计来阻碍他与伊朗达成的关于伊朗核问题的决议的决议。

　　知识点把握：名词A+定语一+定语二(其中定语二可以修饰定语一中的名词也可以修饰名词A，一般根据语境来判断，从考研的文章来看，修饰名词A的可能性更大。

　　参考译文：在年度的国会演说中,巴拉克`奥巴马(Barack Obama)作出数个承诺，包括提高联邦政府员工的最低工资，发行一种新的免税储蓄债券，鼓励美国人多储蓄，关闭关塔那摩湾(Guantánamo Bay)监狱，推进移民政策改革，以及制止任何国会可能会通过的阻碍与伊朗核问题解决方案的命令。
