见附件，2题
解题思路： 见下
解题过程：
1。这里是It is+段时间+since从句，从句中用过去时态；如果从句中是延续性动词，是否定意思，如果是短暂性动词，是肯定意思，所以这句话意思是：晚会的确很精彩，好多年没有玩得这麽开心了。再例如：It is three years since he joined the army.自从他参军到目前已经有3年了。
但如果选that, 就是构成强调句式It is+被强调部分+that+...,;如何判断是强调句式，把框架It is...that去掉，句子仍能成立，那么这句话就是强调句式，而这里去掉It's ...that...，句子剩下Years I enjoyed myself so much.这句话不能成立，所以第二个答案不正确。再试比较下面句式：It is three o'clock when he came back.
It is at three o'clock that he came back.(强调句式）
2.这里in case+句子是“以免，万一”意思。整句话意思是：我想再带800美元钱以免钱用光。in case还可以放于句尾，例如：You'd better take an umbrella in case. 你最好带把伞以免万一。as soon as引导时间状语从句，“一...就..."的意思；as a result ”结果“，后常和句子用逗号隔开；so that引导结果状语从句或目的状语从句，例如：He raised his voice so that his classmates could hear him.(目的状语从句，从句中常有情态动词做标志，”为了“的意思）
He didn't catch the early bus, so that he was late for class.(结果状语从句，前面常和句子用逗号隔开，”结果“的意思）
最终答案：略
