Is electricity a good thing or a bad thing?
A conclusion
Electricity can be both useful and dangerous.It all depends on how we use it.
English words are made up of different parts.
There parts are called syllables.Every word has one or more syllables.
Here are some common adjectives.
clean uncomfortable useful comfortable dangerous
Now,let's put these adjectives into comparative forms.
more uncomfortable
cleaner
more useful
more comfortable
more dangerous
Work out the rules
To make the comparative of adjectives
Add "-er" after words with one syllable.
Add "more" before words with two or more syllables.
There are exceptions:
Add "-er" after multisyllable words ending
with "-ow","able" and "-er".
For multisyllable words ending in "-y",change the "-y" to "-ier".
How many syllable do the following words have?
form cooker computer supermarket electricity
