要解题过程，谢谢了

Answer 1

1. B. 首先看后面的been interested in这个词组，可知该句式用的时态应当为完成时态，因此可以排除c；另，由never引导的句子需要使用倒装句，而且为部分倒装，即只需将助动词提到主语的前面。该句主语是so many people, 完成时态中have为助动词，因此答案选B
2. B. the place 指前面出现的Lijiang， 其做后面visit的宾语，为此关系代词只能用which或that，或者省略不用。A中关系代词where一般修饰地点状语，与句子意思不符，排除。C中visit为及物动词，后面直接接表示地点的名词即可，中间不需要加介词，所以C也排除；D中most作为副词修饰动词通常置于动词后面，因此也排除D
3.C 这个句子考的要点是虚拟语气用法。与现实事实相反的情况下，条件句为过去式，则主句为过去将来时；与过去事实相反情况下，条件句为过去完成时，则主句应为过去将来完成时,结构为would+have+动词过去分词
4.D. 表示家具，要用量词piece， 一件家具就是one piece of furniture

Answer 2

B 这是一个倒装句，倒回来就应该是 in china never have so many people been ...
B it is ...that ....强调句型
C 虚拟语气
B furniture 是一个类似于people的复合词

Answer 3

1B Never+情态动词+主语+动词完成式+宾语 所以答案应该在BD里 然后没有very many这种用法 所以...
2D the place 是动词visit的宾语 所以定语从句的先行词应为关系代词 在从句中做宾语。如果用where的话 后面不加it。D的话 可以理解为前面省去了that
3C 这个没啥好解释的 就是固定句式 would/should/could + have done, if had done 表示与过去事实不相符
4D 也没啥好说的 furniture 不可数
