when a friend gave Jim a ticket to the game ,——go.

答案：couldn't help but
解析：
1、根据前面的gave判断,后面的动词需要用过去式形式,所以排除第二和第四个答案.
2、couldn't help 表示：禁不住,忍不住,后面接动词的ing形式,所以排除第一个答案.
3、couldn't help but 也表示：禁不住,忍不住,但是后面接动词原形,比如：Out of this beautiful campus, I could not help but look back affectionately look.（走出这个美丽的校园,我忍不住回头,深情地望了一眼.）,所以第三个是正确的答案.
祝您学习进步,更上一层楼!O(∩_∩)O~
