The present participle is a form of a verb that ends in –ing and usually follows an auxiliary verb to form the present continuous tense. This tense refers to actions or events that are taking place now.

Examples:

  • Three balloons are rising  steadily into the sky.
  • A noisy crowd is watching  two cocks fight in a cockpit.
  • The burglars were stealing  from drawers. 

In the sentences, rising , watching  and stealing  are present participles.

  • A small dog was chasing  a big cat.

  • “What am I doing ?” “Can’t you see I am thinking ?!”

Examples:

  • I apologized for stepping  on her toes.
  • They finally decided on robbing  a smaller bank.
  • Sometimes Jack and Jill think of going  up the hill.
  • She’s going to concentrate on winning  the game.

Present participle used after conjunction.

In sentences where present participle and conjunction are used, the present participle (–ing form) comes after the conjunction. Such sentences are only possible when the subjects of both clauses are the same.

Examples:

  • Our boss went to play golf in spite of feeling  unwell..
  • Johnny has not been seen since leaving  home this morning..
  • She is paid well for cleaning  the office.
  • When leaving  his bedroom, he never fails to turn off the light.
  • We always have some hot drink after swimming .

Clauses sharing same subject

The –ing clause is usually placed in front of the main clause when describing two actions being done at the same time. Both clauses share the same subject.

Examples:

  • Pointing at the bright object in the sky, he shouted “Look! UFO!”
  • Rowing the boat upstream, we puffed and panted.
  • Diving into the water, he swam to the other side of the pool..
  • Picking up a stone, the boy threw it at a passing train. . 

Clauses having different subjects

When the main clause and the –ing clause have different subjects, the –ing clause should not be placed in front of the main clause as doing so gives rise to a dangling participle  (also known as a dangling modifier ).

Examples:

  • After drinking for three hours, the sky began to get dark.

    (The subject of the main clause must be the one [noun] drinking for three hours. But the subject of the main clause is sky , which is clearly different and wrong. Correction :  After drinking for three hours, we saw/noticed the sky begin to get dark.)

  • Looking at the sky, black clouds are spreading.

    ( Looking at the sky  requires a subject such as I  or we , not black clouds . Since both clauses require different subjects, a dangling participle  will result. Correction : Looking at the sky, I saw black clouds spread across the sky.)

Simple verb form + direct object + present participle

In such a construction, the –ing clause acts as the complement of the object. It indicates what the object, whether it is a person or a thing, is doing. The simple form of the verb can be used in place of the present participle without significantly affecting the meaning of the sentence.

Examples:

  • We watched them  fighting  in the street.
  • We watched them fight  in the street.
  • I saw a couple of ducks waddling  along the river bank..
  • I saw a family of ducks waddle  along the river bank.
  • I heard a clock ticking  somewhere in the house.
  • I heard a clock tick  somewhere in the house.
  • This photo shows him riding  the farmer's cow.
  • This photo shows him ride  the farmer's cow.
  • Someone caught him stealing  a cookie from the cookie jar.
  • Someone caught him steal  a cookie from the cookie jar.

Using 'while'

In the last example sentences above, the conjunction while  could be better used without giving a different meaning to each sentence. The use of while  indicates an action is still going on in the subordinate clause when the action in the main clause takes place.

Examples:

  • We watched them while  they were fighting  in the street.
  • I saw a couple of ducks while  they were waddling  along the river..
  • I heard a clock while  it was ticking  somewhere in the house.
  • This photo shows him while  he was riding  the farmer’s cow.
  • Someone caught him while  he was stealing  a cookie from the cookie jar. 

Using 'with'

When the subjects of the two clauses, main clause and subordinate clause, are not the same, the word with  may be used.

Examples:

  • He walked a long distance with  sweat trickling  down his face.
  • With  a helicopter appearing  above them, they thought it was probably patrolling the coastal waters.
  • With  the sky  clearing , we knew we had the opportunity to go fishing.
