This is the present perfect tense. In this example, Janet is still running when the words were said.)

The present perfect is used to refer to an action that occurred in the past and has present consequences or to an action that began in the past and may continue. On the trip sentences, I would say "I didn't start my trip on Sunday and I still haven't started it (until now)." Perhaps it is the word 'since' that is confusing? We usually use present perfect continuous after since because it describes an ongoing action that started in the past and is still continuing.

Small but powerful, the Perfect TENS unit comes with two separate channels and 8 preset and 1 manual pain relief programmes, each with its own combination of settings to suppress pain in different ways. In addition to the three main tenses of present, past, and future, the English language allows us to make three statements about accomplished facts. We use one of the three perfect tenses to show an action that hthe verb open is a short verb, so, can I use this verb or other short verbs (to be precise, the verbs that occur at a particular moment) Perfect of present state (stating that a present situation holds as a result of something that has happened recently): [8] is much more specific. It could, for example, refer to a recent experience in which a person has behaved in a way that is very brave. It could be that this surprised the speaker, but in any case it refers to a more specific time, a time the context presumably makes clear.

In both sentences, "I lost the key yesterday" and "I have lost the key" are clearly important now, since they are the cause of the current situation ("I cannot enter my home"). However, in the first sentence, the word "yesterday" locates the action "lost the key" at a past moment, so the past simple is used. In the second sentence, no time is mentioned, and the use of the present perfect presents the action as relatively recent and connected to the present topic or situation. If an action was only completed very recently, you can describe it with the present perfect tense. Even though the action happened in the past, it was so recent that it’s directly connected to the present. These cases usually use adverbs like just or now to show that the action happened not long ago. Paingone Easy is perfect for those who want to wear it discretely under their clothing. Keep Paingone Easy on hand whenever pain decides to strike. The machine is simple to use with no wires or gels, and the treatment gives fast relief. It is a great option for those who want drug-free sciatica pain relief. This is the present perfect tense. In this example, David might have finished working with those scientists, but the sentence carries the connotation that he is still working as an entomologist.)This is the simple past tense. In this example, Janet has stopped running when the words were said.) The present perfect can also be used along with future simple tense constructions to describe a future action. In these instances, the present perfect clause is usually preceded by a subordinating conjunction (e.g., “when”, “until”). Examples: Present perfect and future simple I’ll call you as soon as I’ve arrived. I broke my hand in the past and went to a doctor. While the hand was healing I accidentally fell off and after a month spoke to a doctor again and wanted to say that I think I actually made it worse.

More Examples of the Present Perfect Tense

In traditional Latin and Ancient Greek grammar, the perfect tense is a particular, conjugated-verb form. Modern analyses view the perfect constructions of these languages as combining elements of grammatical tense (such as time reference) and grammatical aspect. The Greek perfect tense is contrasted with the aorist and the imperfect tenses and specifically refers to completed events with present consequences; its meaning is thus similar to that of the English construction, "have/has (done something)". The Latin perfect tense is contrasted only with the imperfect tense (used for past incomplete actions or states) and is thus used to mean both "have/has done something" and "did something" (the preterite use). Other related forms are the pluperfect, denoting an event prior to a past time of reference, and the future perfect, for an event prior to a future time of reference.
