-ing forms as subjects  Smoking is bad for you.






                 We often use -ing forms (also called 'gerunds') as subjects -  more often than infinitives.

                 Smoking is bad for you. (More natural than To smoke is bad for you.)
                 Swimming is good exercise.  Driving makes me tired.  Travelling takes a lot of my time.

                    2

                    3


                 We can put objects after -ing forms.

                 Learning languages is difficult and takes time. (NOT ... are difficult... - learning is singular.)
                 Eating chocolate does not make you slim.


               ^     Complete this list of activities with verbs from the box (use -ing forms). Then number
                    them in order of interest: 1  = most interesting (for you); 8 = least interesting.

                    ............................ children  .......   ............................ clothes.......



                 In notices, you often see NO before -ing forms.
                 NO SMOKING       NO WAITING


               fa  GRAMMAR AND VOCABULARY: public notices
                    Which words go with which notice?

                    Use a dictionary if necessary.

                    NO PARKING  ..f..      NO SMOKING  ......
                    NO FISHING  ......     NO CYCLING  ......
                    NO CAMPING  ......









               In some answers, both contracted forms (for example I'm, don't) and full     INFINITIVES AND -ING FORMS  131
               forms (for example lam, do not) are possible. Normally both are correct.
