Answer 1

1、C，let us的祈使句用 will you，而let's的祈使句用shall we。
2、B，还是祈使句的用法。由谓语动词heard of 可以判断这句是过去式，前面用了否定词never，所以后面要用肯定的did you。
3、C，这是个感叹句。weather是不可数名词，做表语，不用带冠词。
4、D，门一开他们就冲进大厅，as sonn as 表示一...就...。
5、C吧，这题明显是选择表原因的连词，排除A。because表原因时语气最重，可能性最大，for表补充的原因，since语气介于两者之间，由may看出这是个猜测，选since比较恰当。
6、C，这是个常见的用法，我喜欢打篮球，约翰也是，so指代打篮球这件事。前句的谓语是动词like，只能用do的适当形式代替，配合第三人称John用does。so是副词，前置时要倒装，所以选so does john。
