回答：1.D我的衣箱一定是在旅行中被弄坏了，因为箱盖怎么都合不拢。用情态动词加 have done 表示对过去事物的猜测（有把握的）,stay是半系动词 ，后面直接可以与形容词连用，close 表示距离接近，tight则表示系紧，密封
2。C这个科学家已经死了好多年了。die表示瞬间动作，不可与段的时间状语连用，dead为形容词，表示状态，常与段的时间连用
3。B 由时间状语in the past five years可以判定为现在完成时态，意思是一直与疾病作战，come 前省略了have
4。D 用进行时态表示一种赞叹，反感或厌恶的情绪，常与always ,forever连用，这一类的副词位置应当是实意动词前面，系动词的后面，助动词情态动词的后面。
