Answer 1

1.when did对时间提问用when
2.how much对重量提问用how much ,因为是不可数名词（可数用how many）
3.when /hold 对时间提问用when,动词用原形，因为did以显示出是过去式
4.how long对一段时间提问用how long
5.A 因为fuel是不可数名词，前面不能加冠词，所以排除b d.因为题目问的是这些车用的是什么原料，只能选A
6.C a应该是it is ,b what a ,d how great
7.D fun是不可数的，前面不能加冠词，题目是对名词fun加强语气，用what，how是对形容词等的加强
8.A 对形容词和副词加强语气用how,排除c d。b应改为slowly
9.what an
10.B 记句型find it adj. to do sth
11.B
12 C在此，food不可数前不应该有冠词
