    passive

    I have highlighted the passive sentences, please help check:

    By plucking out a few hairs, researchers are growing skin grafts from
    patients’ own cells.The technique, called EpiDex, has been developed
    by Modex Therapeutics, a Swiss company. It could replace the
    painful removal of skin from other parts of the body for grafts or
    tissue culturing.

    The procedure involves taking adult stem cells, which are found in
    hair follicles, and transforming them into skin cells.
    Doctors take
    between 20 and 100 hairs from any point on the patient’s body – but
    mainly the scalp – and send them to Modex, which grows the skin.
    The stem cells are laid out on trays placed above a layer of unrelated
    human cells provided by a single donor.
    They secrete factors that
    help cause the stem cells above change into epidermal ones called
    keratinocytes. The next step is to expose the cells to air to turn them
    into skin.

    Re: passive

    I understand why these two sentences are passive, but what I don't understand is why the other sentences are not called passive? Why only these two passive sentences has een used?

    Re: passive

    The verbs are active:

    By plucking out a few hairs, researchers are growing skin grafts from patients’ own cells.

    are growing is a present continuous verb; i.e., BE + -ing. Passive verbs look like this--take a look here.

    It could replace the painful removal of skin from other parts of the body for grafts or tissue culturing.


    The procedure involves taking adult stem cells, which are found in hair follicles, and transforming them into skin cells.

    Hey Soup, didn't you overlook "which are found in hair follicles"? And wouldn't you accept the telescoped relative clause "(which is)called Epidex.."?

    That means we can say this is another passive sentence?

    Actually, these two examples are not sentences, they are parts of the sentence "The technique....a Swiss company."

    So it would be better to say that they are:

    examples of the passive form of the verb/examples of the passive voice.

    In a way, yes, and no.

    Teaching isn't about answers. It's knowing when, where, and how to lead learners towards finding patterns of meaning on their own.
