◇I hear someone singing.
I am hearing someone singing.
◇Do you see anyone over there?
Do you see anyone over there?

◇Are you staying here till next week?

Some verbs are in the present continuous tense from the structure point of view, but they express what will happen in the future, rather than indicating that the action is currently taking place. These verbs are often verbs that express changes in position, such as: go, come, leave, fly, move, start, begin, arrive, stay, return, etc.

◇My aunt is leaving for Shanghai at eleven o'clock tomorrow morning.

2. Not all verbs have progressive tense. Some verbs generally cannot use the present continuous tense in sentences, but use the present simple tense. These verbs are often verbs that express emotional states, perceptions, wishes, or transience. For example: see (understand), know (know; understand), want (need; want), like (like), hear, have (have), think (think; think), hope, hate, etc.
3. In time and conditional adverbial clauses, the present continuous tense can sometimes be used instead of the simple future tense.
