2) Comparison 

You can use comparative adjectives or comparative adverbsto say that something has more of a quality than something else, or more thanit used to have. Another way of comparing things is to say that it has more ofa quality than anything else of its kind. You do this by using superlativeadjectives or superlative adverbs. It is also possible to makecomparisons by using words and structures which indicate that something is thesame as something else or is done in the same way, such as “as”, “as … as”, “like”,“the way”, “same”, “similar”, “alike”, just to name a few.

For example:

The familymoved to a smaller house.

  Now we come to the most importantthing.

  It isJapan’s third largestcity.

Jane was not as clever as him.

They all looked alike.
