请老师详细解释，谢谢~！

Answer 1

第一题，the first /last /very /exactly 等修饰的名词作先行词，后面只用that不用 which 。
第二题，主干是the exciting day came ，all the american fans look forward to 是定语从句修饰day ,came 是用作谓语动词。
第三题，we call 是定语从句修饰the lady .

Answer 2

1.被修饰的词如果是序数词（the first idea），这种情况下，定语从句的引导词用that。
2.The exciting day （all the American basketball fans looked forward to）括号内的是定语从句，起修饰作用，充当the exciting day的定语。现在只看主干：the exciting day came at last，显然选came。注意：look forward to是一个陷阱短语,高中这种破题很多，看清楚。
3.呃……Jane问的是你愿意跟谁说话，你回答的时候当然是人的名字了，所以选A“（我们称作怀特小姐的）女士”，括号内为定语。而B是“这位女士叫怀特”，显然答非所问么。

Answer 3

1.因为有the first/the last /very /just，有序数词和最高级用that

2.looked forward to 修饰The exciting day
是looked forward to the exciting day ，缺谓语，所以用came

3.这是一句定从，省略了关系代词that/who ，we call 修饰the lady
