答案

1、have sb do sth 是让某人做某事,这里的have是表示一种状态,就像 I have a pen一样,意思是“有”,单选选的是最符合语境的选项,这里.have sb do sth的理解比较牵强,意思是：疯狂英语让学生们参加网上课程.但事实是,学生们参加网上课程是一个自己主动,自发自愿的行为,而非被动的.
所以这里用非谓语更贴合语境.
2、如果前面的句子是祈使句,那么就是一个完整的句子:turn to the right.
而逗号后面又是一个完整的句子：you will find the house you are looking for.但是英语里面和汉语不同的地方就是,逗号不能连接两个单独的句子,必须要用连词,比如 and,but,therefore,then等等.
所以,这里不能用祈使句,这样会少了两个句子的连词,而只能用非谓语形式.
3、这里也是一个“最优解”的问题.when（当）强调的是时间点,as（随着）侧重的是动态变化的过程.这里用as更贴切.
4、选择Bwill
意思是：随着你们产品越卖越好,你们公司的声誉也会更好的.
这里,名声是随着产品销量的提高而变好,现在并没有变好,而是对未来的预期,用will比does合适.
5、The album might well have caught on had it been less expensive.
had it been less expensive 是虚拟语气的倒装,完整的原句是：if it had been less expensive
The album might well have caught on.是主句.
catch on 是流行起来的意思.
整句话的意思是：如果这张专辑的价格能再便宜些,那么很可能它能流行起来.
