at many times.开头的句子要倒装嘛?

问题描述:

at many times.开头的句子要倒装嘛?
1.At many times——how alcohol makes.
A.Amy notices B.does Amy notice
2.Detemining the mineral content of soil samples in an exacting process;——experts must perform detailed tests to analyze soil specimens.
A.so that B.however C.afterwards D.therefore
2.我知道B不可以,因为要加逗号
应该选择社么?
请告之及其解释

1,如果不倒装的话
at many times后面要加逗号
2,两个句子是因果关系
而so that和therefore都有这个意思
但是,因为用的是分号,后面要有个完整的句子
so和and,but一样,不能做单独句子的开头
所以选D
