第一题,我认为题目不怎么好,因为如果从不同的理解角度看(大多数问题本应该解决或者不会发生,如果.),选择B也是可以的,
第二题这种冠词的麻烦大家帮忙讲解下
不好意思 第二题选A
第一题选d比较合理
should have done 指的是本应该而实际上没有发生,题目的本意是发生了,所以填could比较合理
第二题
（英语名词根据其意义可分为普通名词 (Common Nouns）和专有名词（Proper Nouns）.普通名词又分为类名词、集体名词、物质名词、抽象名词.
1、类名词：book,table,house
2、集体名词：family,crowd,army
3、物质名词：milk'water'honey
4、抽象名词：honesty,hapiness,love
）
photocopier 影印机;复印机,很显然属于物质名词.英语语法：专有名词,物质名词,抽象名词,人名,地名等名词前,一般不加冠词!
the 表特指!
回答完毕!
