THE SIMPLE PRESENT TENSE

The PRESENT TENSE uses the verb's base form (write, work), or, for third-person singular subjects, the base form plus an -s ending (he writes, she works).
The PRESENT TENSE indicates that an action is present, now, relative to the speaker or writer. Generally, it is used to describe actions that are factual or habitual -- things that occur in the present but that are not necessarily happening right now: "It rains a lot in Miri" is a kind of timeless statement. Compare that to the present progressive -- "It is raining in Miri" , which means that something is, in fact, going on right now.

The present tense can also suggest a past action: "Daphne tells me that she took her brother to the dentist." Most oddly, the present tense can convey a sense of the future, especially with verbs such as arrive, come, and leave that suggest a kind of plan or schedule: "The train from London arrives this afternoon at two o'clock."



Present tense habitual activities are frequently signaled by time expressions such as the following:
all the time,always,every day,every hour
most of the time,never
often,rarely,sometimes,usually
