16.Faults in the earth's crust are most evidently in sedimentary formations,where they interrupt previously continuous layers..这题我不知道从何下手!!

18.Four huge shield volcanos have been observed on Mars, as well as a great number of smaller ones like found those on the earth.

可以看出前半段是一个名词性词组，所以这里用介词就可以了。if 一般用做连词，句子结构要完整

evidently这里只要用形容词形式就可以了。不用副词。

是词序问题，like those found on the earth
