13. Important Note about Present Continuous!
Some verbs are NOT typically used in the present continuous tense. Instead, we prefer to use these verbs in the simple present.
These verbs are called STATIVE (or non-action) verbs. Here are some examples:
want
like
love
hate
know
believe
understand

14. Spelling To make continuous verbs add -ing to the base verb:
do becomes doing ask becomes asking
silent 'e'
When the verb ends with a silent e, drop the e and add -ing:
make becomes making take becomes taking

15. one-syllable verbs
For short, one-syllable verbs, that end with consonant + vowel + consonant (CVC), we must double the last consonant and then add -ing:
swim becomes swimming run becomes running

16. w, x and y
For words that end w, x and y, do not double the last consonant; just add -ing:
enjoy becomes enjoying study becomes studying
-ie verbs
For verbs that end in -ie, change the ie to y before adding -ing:
die becomes dying

17. Clue words Now, right now, at present, presently, for the time being,
currently,
at the moment, at the present.
