Question

sat 语法题.
Although she considers her chemistry reserch completed,she has heeded her professor's advice and (is conducting)three additional experiments.
为什么在and后面的这句话可以省略主语呢?我觉得还是要加上she is conducting.
如果she可以省略.可以再举几个句子吗?

Answer 1

Although she considers her chemistry reserch completed,she has heeded her professor's advice and she is conducting three additional experiments.
Now the above sentence is wordy and unidiomatic.
(Now the above sentence is wordy and it is unidiomatic.-----This sentence is again wordy and unidiomatic.)
