Answer 1

1. 分解句子结构：Finally the moment【 the children ________ for】 came as the Santa claus stepped into in the room.
【】：定语从句，修饰moment。所以空处是谓语动词，根据后文stepped知时间为过去，为表示持续性动作，用完成进行时，即A。
2. 将原句还原成陈述句： The government of China had who______those earthquake-stricken people in Haiti.
所以空处为have+do，选原型rescue。
3. ---Hey! What's the rush?

---The bank ______in half an hour and I need to cash a check.
一般现在时表示常规动作，银行关门是规律性的，故选一般现在时。
4.This road is in very bad condition. It __________a long time ago.
should have done 表示本应该做而没有做的事，与原题语境最贴切。

5.Do you think she _____still be working ?

---No. I don’t think so. It’s very late.
没什么可说的，疑问句表推测只有can。

6.First______ abroad, the art of sand painting is finding a home in China.
也没什么可说的，这是固定格式，独立主格结构done表被动。

7._____things are much more expensive now. There has been _____big rise in the cost of living.
第一个空，因为没有任何范围限制，所以无任何冠词；第二个空，a rise意为一次上涨，用不定冠词a。
有帮助的话，就选最佳吧。

Answer 2

the moment came,came 是过去时，而且是小孩一直在期待，所以用had been waiting
should have done表示本应做而没有做，而这里应该用被动语态。
我想你应该疑惑的是may把，may不用于表示是否可能的疑问句。
started就强调个过去。
泛指的复数可数名词前零冠词。a big rise这很常见（我在想是不是因为rise抽象名词），而the明显不对了。
不好意思，能力有限，2，3不好解答。希望能帮到你。
