分析 一架俄国飞机在空中解体了,导致机上224人死亡,这件事被认为是由伊斯兰国在飞机安装的炸弹造成的.
解答 答案:A.
根据句子结构A Russian plane(主语) broke up(谓语) in the air(地点状语),_____ all 224 people on board(飞机爆炸的必然结果状语) which (引导定语从句,which代指主句)was believed _______ (believed的宾语)by a bomb planted by Islamic State.可以看出第一个空是结果状语,是飞机爆炸的必然结果,所以用killing;第二个空是be believed 的宾语,表示认为已经被做,所以to have been caused,因此答案是A.
点评 考查现在分词和动词不定式.动词不定式的常用形式:
1.to do后面表示的是将来,代表某人被认为 将要做某事.
2.to be doing 表示的是现在进行,代表某人被认为 目前正在做某事.
3.to have done表示的完成,代表某人被认为应经做过某事.
