【分析】
要找出句子中动词的现在完成时形式，需先明确现在完成时的基本结构：助动词have/has + 动词的过去分词，同时注意不同句式（肯定、疑问、否定）中助动词的变化：疑问句将have/has提前，否定句在have/has后加not（缩写为haven't/hasn't）。解题时，先定位每个句子的助动词，再找到对应的实义动词的过去分词，组合后即为现在完成时形式。
【解析】
1. 句子主语为第一人称I，助动词用have，实义动词see的过去分词是seen，故现在完成时形式为have; seen；
2. 该句为一般疑问句，助动词Have提前至句首，实义动词visit的过去分词是visited，故为Have; visited；
3. 句子主语为第三人称单数She，助动词用has，实义动词leave的过去分词是left，故为has; left；
4. 句子主语为复数They，助动词用have，实义动词finish的过去分词是finished，故为have; finished；
5. 该句为否定句，助动词为have的缩写形式haven't，实义动词hear的过去分词是heard，故为haven't heard。
【答案】
1. have; seen 2. Have; visited 3. has; left 4. have; finished 5. haven't heard
