翻译:我们有/度过了心急如焚的两周/几周,等待着实验的结果.
解释:
1. 此题是一个简单句,所以只能有一个谓语动词had,所以选项必须做状语,即必须选用动词wait的非谓语形式,排除动词原形A wait;
动词非谓语形式一般指动词现在分词/不定式/动名词/过去分词.
2. 句子主语We(同时也是非谓语动词wait的逻辑主语)和状语动词wait之间明显为主动关系,必须选用其现在分词形式,排除BC.
B为不定式的进行式,而不定式在句中一般只做目的状语“为了...”和结果状语“结果...”,此时句意不通;
C为过去分词,表明we和wait之间为被动关系,排除.
3. 综上所述,正确答案为D,其中现在分词短语waiting for...为伴随状语.
注:a couple of意思是“一双/对”或“几个/若干”,即类似于a pair of或a few.
