the cpmparative form of adjectives and adverbs

Use the comparative form of an adjective to compare two nouns. To form the comparative, add "-er" to most one-syllable adjectives. If the adjective ends in "e," add "-r." If it ends in a consonant-vowel-consonant pattern, double the last consonant and add "-er." The comparative form may be followed by "than" + noun phrase.
用形容词比较级比较两个名词。大多数单音节形容词只须加 "-er" 就可构成比较级。如果形容词的结尾是 "e"，您只须在后面加 "-r" 。如果它的结尾是辅音＋元音＋辅音结构，则须将末尾的辅音重叠，并在后面加"-er"。比较级后面可以跟上 "than" + 名词词组。
small-smaller, safe-safer, hot-hotter
