Introducing English Verb Tenses
Editors note: This is the first of a four-part series on verb tenses. Click here for part two.
For VOA Learning English, this is Everyday Grammar.
Today we are going to give you a basic overview1 of the verb tense system in English.
Verb tenses tell us how an action relates to the flow of time.
There are three main verb tenses in English: present, past and future. The present, past and future tenses are divided into four aspects: the simple, progressive, perfect and perfect progressive.
There are 12 major verb tenses that English learners should know.
English has only two ways of forming a tense from the verb alone: the past and the present. For example, we drove and we drive.
To form other verb tenses, you have to add a form of have, be or will in front of the verb. These are called helping2, or auxiliary3 verbs.
Time, culture, and grammar
Verb tenses can be difficult to learn in a foreign language. Different cultures think different ways about time. Chinese, for example, has no grammatical4 verb tenses. Other languages, like Indonesian, express time only through adverbs — there are no changes to the verb form.
English verb tenses give many details about time and action such as:
Is the action finished? How long did the action happen? Was the action repeated? Did the action happen at a known or unknown time? Is the action a habit? Is the action planned or spontaneous5?
It is difficult to think about time distinctions that do not exist in your own language. So, it can take many years for English learners to master verb tenses.
Let’s get started. We are going to give examples of all 12 verb tenses using the verb drive.
Simple Tenses
We’ll start with the simple tenses. These are probably the first tenses you learned in English. Simple tenses usually refer to a single action. In general, simple tenses express facts and situations that existed in the past, exist in the present, or will exist in the future.
Progressive (Continuous) Tenses
Let’s go on to the progressive tenses. We use progressive tenses to talk about unfinished events. Progressive tenses are also called continuous tenses.
Perfect Tenses
Now let’s look at the perfect tenses. Perfect tenses cause the most confusion6. To put it simply, they express the idea that one event happens before another event.
There are many tricky7 exceptions with the perfect tenses, which we will discuss in a future episode8. The adverbs never, yet and already are common in perfect tenses.
Perfect Progressive Tenses
Finally, let’s look at the perfect progressive tenses. Generally, perfect progressive tenses express duration, or how long? Perfect progressive tenses usually include the adverbs for or since.
Don’t worry if you don’t understand everything yet. Here are some recommendations9 we have for learning verb tenses.
Adverbs are your friends
First, think of adverbs as your friends. Adverbs of time offer valuable clues about the correct verb tense.
Let’s use the adverb ago. Ago is only used in the simple past as in, “I left home three years ago.” The adverb ago is never used in the present perfect. Certain adverbs occur with certain verb tenses.
Keep it simple
English learners sometimes try to impress people by using complex verb tenses. You often have a choice of several verb tenses. When you do, always choose the simplest one. It will be clearer for your listener, and there is less chance of making a mistake.
Practice with questions
Native speakers don’t think consciously about verb tenses. With enough practice, English learners can internalize the verb tense system, too. Instead of worrying about deep time relationships, try using adverbs and your ear to choose the right verb tense.
Often when someone asks a question, you can respond in the same verb tense. We’ll ask a question in each verb tense. Give an answer in the same tense, then listen to our answer.
