1\D
根据otherwise可以判断出要用虚拟语气。表示过去发生的事要用would have scored。译文：在踢球前他犹豫了一会儿，否则他就会射中球门。
2\A
这是1998年的大学4级考题
for all，意思是＇尽管＂,＂虽然＂比如：He may be naughty and annoying, but he is a good boy for all that.
尽管他淘气又惹人讨厌,他还是一个好孩子。
又比如：He never stopped trying for all his failures.
尽管他失败, 但他从没放弃努力。
。句中的their differences，obvious and genuine affection可确定选项中的转折词只能是for all．
but for要不是;above all最重要，首先；Except for除了（例句：Nothing remains except for me to say goodbye.最后我该说一声再见了.）
３＼A
个人感觉是，并不值得信赖的答案
理由：where 的先行词是Beijing
全句的理解可以是这样的：我１９９５年来到北京，这就是４年后我成为医生的地方．
其他的选项带进去不通．
