1.The timing may have been choreographed for the decision by the Ukraine authorities is just the sort of news president Barack Obama wants to hear.

参考翻译：这个时间可能是经过精心策划的，因为乌克兰当局宣布的决定正是奥巴马总统希望听到的消息。

语法学习：may have been对过去的猜测。如果是must have saved则是对过去事实肯定的猜测。

may用来表示某事已经发生：（may + have + 动词的过去分词）

You may have read some account of the matter.（关于这件事你可能已经听过一些描述
了。）

Mathews may have written that letter.（马修斯可能已写了那封信。）

注：may和might表示"可能"时一般不用于疑问句。表达疑问时要用别的说法。例如：

Is it likely to rain,do you think?（错误的句子是：May it rain?）

表示否定时要用can't或couldn't("不可能"）。

2.The body of the Polish president’s wife has now been identified following Saturday’s plane crash in Russia, in which she, her husband Lech Kaczynski, and dozens of senior Polish political and military officials were killed.

参考翻译：周六在俄罗斯的空难过后，波兰总统夫人的遗体已经经过辨认。在这次空难中，卡钦斯基夫妇，几十名波兰高级政治和军事官员遇难。

结构分析：这句话的主干是前面部分：The body of the Polish president’s wife has now been identified。following Saturday’s plane crash in Russia是现在分词作状语。in which引导定语从句，修饰的是plane crash。

3.On Friday, Russia said it was considering suspending all such adoptions after a 7-year-old Russian boy was sent back to Moscow unaccompanied when his adoptive American family rejected him.

参考翻译：周五，一名7岁的俄罗斯男孩在无人陪伴的情况下被他的美国领养家庭送回莫斯科，俄罗斯表示将考虑终止所有类似的收养行为。

结构分析：这句话的前半部分是主干。after后是时间状语从句。when his adoptive American family rejected him也是时间状语从句，但是这里的状语补充说明的是was sent back to Moscow的时间。
