The document discusses the present tenses in English. The present simple is used for present and routine actions, using time expressions like every day or adverbs of frequency. Its form is subject + verb + complement. The present continuous is used to talk about actions happening now, using time expressions like now. Its form is subject + to be + verb + -ing + complement. Both tenses have exceptions - the present simple adds -s to verbs for he/she/it subjects, while the present continuous is not usually used with stative verbs.
