There are many things to consider in this issue:
1) Chickensmoothie is an english-based site. If you can't write even just basic english you're going to have trouble connecting with the other members in every aspect of the site.
2) The shop/adoptable owner has the right to give away their things in a way that makes them comfortable and gives them an easier time to control and dispense their work. For the most part, this is not intending to deny people with poor english, merely making their life a little easier.
3) With most adoptables, there was some sort of unique idea or thought behind the image, and when you give that image away, you want someone who adopts it to either have a likeminded view or impression of the image, or perhaps better impression, in order for that adoptable to be put to good use. Giving things away or adopting things for the sake of adopting them would seem to be undermining the time and dedication put in by the artist with each adoptable, even if some look more time-dedicated than others, the fact it's there shows they want to give others something they worked on and make others happy.
4) If you don't feel like you can apply to things, perhaps you could spend some time by yourself or with a friend working on some pretend applications, or making up some stories or ideas to help you improve your writing and application style for story-based adoptables. if you already have adoptables with no story, start there? Make them up some stories or adventures, it will give you a better idea of how a character is more than a pretty picture that you paid a dog for.
5) If you really don't want to write, find other adoptables

There are plenty out there that are given away strictly for pets, for free, by random draw/lotto, or by custom order. There's no limit to what you can acquire if you search.
I personally prefer adoptable shops that give at least some away with an even opportunity, like number draws or random generated pick or whatnot. In example with some of my old adoptables, you can get them first serve (or ninja), by random selection, by story, by quiz question, etc. You really can find some good stuff out there without having to be a Charles Dickens
