as这里是连词,“和...一样”的意思,如果完整地说出来是: She is a doctor, as her husband is a doctor.和她丈夫是个医生一样,她也是个医生。这样重复没必要,尤其是英语很忌重复,所以说成She is a doctor, as her husband is.和她丈夫一样,她也是个医生。不倒装也是正确的,不一定要倒装,但习惯是倒装。
Shortsighted people have to wear glasses, as do longsighted people.近视眼的人要戴眼镜, 远视眼的人也要戴. =as longsighted people do
The photograph still remained, as did many memories. 那张照片还挂在那里, 许多往事也仍历历在目.
有时不能倒装:She is a fine singer, as her mother used to be.
