Present continuous

We use present continuous:
 Current activities.
I’m travelling by coach.
 Temporary situations.
They’re living in mexico for a year.
 Planned future arrangements.
I’m meeting my grandmother in ten minutes.

Notes
1. Certain verbs are not normally used in the present continuous tense. These are:
 Verbs of thinking and poinion, e.g. agree, believe, expect, forget, imagine, know, mean, prefer, realise, remember, suppopose, think,* understand.
 Verbs of emotion and feeling, e.g. feel, hate, hope, need, like, love, want, wish.
 Verbs of the senses, e.g. hear, look, notice, recognise, see,* seem, smell, taste.
 Verbs of having and being, e.g. be, belong, contain, have,* own.
 Other verbs, e.g. cost, depend, matter.
*The verbs have, see and think can be used in the present continuous but the meaning is not the same as in the present simple. Have with an appropriate noun can mean eat drink, take, give, ,e.g. he’s having lunch/a drink/a shower/a party. See can mean go out with or meet, e.g. She’s seeing a friend/her boyfriend this evening. Think can mean consider, e.g. I’m thinking about the question.

2. Spelling of the –ing form.
 We usually add –ing to the infinitive,e.g. eating, watching.
 When the infinitive ends in one e we delete the e,e.g. have/having, write/writing.
 When the infinitive ends in a stressed syllable of one vowel and one consonant(not y or w), we double the consonant, e.g. put/putting , forget/forgetting.
 In British English when the infinitive ends in an unstressed syllable and letter l , we also double the consonant,e.g. travel/travelling.
 If the consonant is ay or a w, we don’t double it, e.g. say/saying, row/rowing.
