[Hammamet]

Hi!
I'm having a little trouble with sentence analysis, can anyone help me?

AImagine B[wearing a jacket or rucksack C[that charges up your mobile phone D[while you take a walk]A]B]C]D
A - main clause
B - subordinate nominal participial object clause
C - subordinate attributive clause
D - subordinate adverbial clause od time

How bad am I?

Thanks!

Hammamet, I'm not familiar with some of the terms you're using, but from what I can see, your analysis is good.

main verb: imagine
verb's object: (that you are) wearing a jacket or rucksack
relative clause: that charges your cell phone
adverbial clause: while you take a walk

Does that help?
