Question

一道SAT语法问题求助
(When looking) at modern photographs of that area of Indonesia,the effects of the 1883 eruption of the volcano Krakatau are still evident.
答案选了那个括号
它错哪了呢,是不是缺少一个主语,导致主语变成了the effects呢?应该怎么改呢?

Answer 1

effects 无法 看照片,当句子以动词ing或者ed形式开始,那么逗号后面的第一个主语就是前面的主语.可以改为 When looking at modern photographs of that area of Indonesia,we found the effects of the 1883 eruption of the volcano Krakatau are still evident
