If you said that both word groups need to have was or is or some other word inserted after the subject, you're well on your way to understanding what participles are and how they work in sentences. What you've seen is that a participle is part of a verb, that by itself aparticipal can't serve as the main verb of a sentence.
Because they're so convenient and effective, participals deserve a closer look.
You may also have noticed that there are two different kinds of participles: present and past. A present participle is formed by adding ing to the verb stem. The result is the form that would be used with the helping verb is. The past participle is the verb form that would be used with the helping verb have, and it is usually, but not always, formed by adding ed to the verb stem. The chart below shows how this works.
While the participle can't serve as the main verb of a sentence without its helper, it can be used, either alone or in combination with other words, as a modifier:
[Formed over ten thousand years ago,] these lava beds have changed very little.
Every evening we could hear a bell [ringing somewhere in the distance.]
In the preceding sentences, the bracketed word groups are called participial phrases. The underlined words are those the phrases modify. It's important that your reader can immediately see exactly what the phrase modifies. Notice the possibilities for confusion in the following sentences.
Bill found a rusty pocket knife climbing the volcano.
Curling gently around the mountains, Sarah watched the clouds.
In both cases, confusion results from the fact that the phrases are positioned too far from the words they modify. Can you revise the sentences to eliminate the problem? If not, or if you have problems with the following activities, review the discussion of Misrelated Modifiers in Six Problem Areas.
