【精析】考察虚拟语气。it is/was+adj+that从句，此句型中当形容词为 natural (自然 的), necessary (必须的),important (重要的),essential (本质的)，strange(奇怪的)时，that从句要用should+do的形式。Should可省略。
【解析】本题侧试反意疑问句的用法。如果陈述部分含有表示否定意思的词，如never, seldom , hardly, little疑问部分要用肯定式。故选择C。例如:He never watches TV, does he?(他从不看电视，是吗?)
【解析】本题测试虚拟语气在表语从句中的用法。suggestion, proposal, request; command等名词后面的表语从句和同位语从句中，用“should十动词原形”表示虚拟语气，而且should可以省略。
【解析】本向为“It is…time since+从句”句型，从句中谓语动词用过去时，故选C。例如:It is many years since World War II was over.(自从第二次世界大战结束尽来已经很多年了。)
