Hi
Present Perfect Simple is used with :
a] recently completed actions :
e.g. I have just finished my breakfast.
b] past actions completed in an unspecified time :
e.g. She has seen that movie but she doesn`t mind watching it again.
c] with time expressions : for years, for two/three..years, for two/three..months, for ages, for a long time, since last week, lately, recently, before, always, this morning/ afternoon..., today, yest, so far, already, etc.
e.g. He has not seen her for ages.
d] asking if an action has been completed:
e.g. Have you finished your breakfast yet? No, I haven`t finished it yet.
e] future actions[ in time clauses]:
e.g. You can go out as soon you have finished your lunch.
The degree of comparison of adjectives and adverbs is quite a large topic, but I will try to give you some examples. There are some irregular adjectives :
little ---less---the least
much/many---more---the most
old -older / elder---the oldest/ the eldest
good----better---the best
far----farther/further----the farthest / the furthest
One syllable adjectives and adverbs usually take "-er" in the comparative and "-est" in the superlative
hot ----------hotter-------the hottest
busy---------busier----------the busiest
tiny--------tinier----------the tiniest
fat--------fatter----------the fattest
fast--------faster-----------the fastest
big----------bigger----------the biggest
bad/ill------worse-------the worst
Adjectives formed of two or more syllables take the morphemes "more" and "most"
e.g. beautiful ----more beautiful-the most beautiful
difficult------more difficult---------the most difficult
but, there are some exceptions, as well :
clever----cleverer---the cleverest
narrow----narrower----the narrowest
