1 The present tenses Main points * There are four present tenses - present simple (`I walk'), present continuous (`I am walking'), present perfect (`I have walked'), and present perfect continuous (`I have been walking'). * All the present tenses are used to refer to a time which includes the present. * Present tenses can also be used for predictions made in the present about future events. 1 There are four tenses which begin with a verb in the present tense. They are the present simple, the present continuous, the present perfect, and the present perfect continuous. These are the present tenses. 2 The present simple and the present continuous are used with reference to present time. If you are talking about the general present, or about a regular or habitual action, you use the present simple. George lives in Birmingham. They often phone my mother in London. If you are talking about something in the present situation, you use the present continuous. He's playing tennis at the University. I'm cooking the dinner. The present continuous is often used to refer to a temporary situation. She's living in a flat at present. 3 You use the present perfect or the present perfect continuous when you are concerned with the present effects of something which happened at a time in the past, or which started in the past but is still continuing. Have you seen the film at the Odeon? We've been waiting here since before two o'clock. 4 If you are talking about something which is scheduled or timetabled to happen in the future, you can use the present simple tense. The next train leaves at two fifteen in the morning. It's Tuesday tomorrow. 5 If you are talking about something which has been arranged for the future, you can use the present continuous. When you use the present continuous like this, there is nearly always a time adverbial like `tomorrow', `next week', or `later' in the clause. We're going on holiday with my parents this year. The Browns are having a party next week. 6 It is only in the main clauses that the choice of tense can be related to a particular time. 2 In subordinate clauses, for example in `if'- clauses, time clauses, and defining relative clauses, present tenses often refer to a future time in relation to the time in the main clause. You can go at five if you have finished. Let's have a drink before we start. We'll save some food for anyone who arrives late. 7 The present simple tense normally has no auxiliary verb, but questions and negative sentences are formed with the auxiliary `do'. Do you live round here? Does your husband do most of the cooking? They don't often phone during the week. She doesn't like being late if she can help it. 3 The past tenses Main points * There are four past tenses - past simple (`I walked'), past continuous (`I was walking'), past perfect (`I had walked'), and past perfect continuous (`I had been walking'). * All the past tenses are used to refer to past time. * The past tenses are often used as polite forms. * The past tenses have special meanings in conditional clauses and when referring to imaginary situations. 1 There are four tenses which begin with a verb in the past tense. They are the past simple, the past continuous, the past perfect, and the past perfect continuous. These are the past tenses. They are used to refer to past time, and also to refer to imaginary situations, and to express politeness. 2 The past simple and the past continuous are used with reference to past time. You use the past simple for events which happened in the past. I woke up early and got out of bed. If you are talking about the general past, or about regular or habitual actions in the past, you also use the past simple. She lived just outside London. We often saw his dog sitting outside his house. If you are talking about something which continued to happen before and after a particular time in the past, you use the past continuous. They were sitting in the kitchen, when they heard the explosion. Jack arrived while the children were having their bath. The past continuous is often used to refer to a temporary situation. He was working at home at the time. Bill was using my office until I came back from America. 3 You use the past perfect and past perfect continuous tenses when you are talking about the past and you are concerned with something which happened at an earlier time, or which had started at an earlier time but was still continuing. I had heard it was a good film so we decided to go and see it. It was getting late. I had been waiting there since two o'clock. 4 You sometimes use a past tense rather than a present tense when you want to be more polite. For example, in the following pairs of sentences, the second one is more polite. Do you want to see me now? Did you want to see me now? I wonder if you can help me. I was wondering if you could help me. 5 The past tenses have special meanings in conditional clauses and when referring to hypothetical and imaginary situations, for example after `I wish' or `What if...?'.

Tense and Voice 时态和语态
I. Tense
By tense, we mean a grammatical category indicating when and how a stated action takes
place. In theories of modern linguistics, English has two tenses, present and past; and two aspects,
progressive and perfect. But more prevailing in China’s EFL teaching is a traditional view that the
tense contains two concepts, time and aspect. The former includes past, present, future, and past
future; while the latter covers simple, continuous, perfect, and perfect continuous. In consequence,
it is generally believed that there are sixteen tenses in the English language. Another important
point about tense in English is that different tenses are indicated by different verb forms, involving
the use of auxiliary verbs. In the Chinese language, however, there is no grammatical tense and the

Tense Usage and Usage Patterns
Tense is a grammatical concept that indicates the time at which an
action or event takes place. The English language has various
tenses, each with its own specific usage and patterns. In this article,
we will explore the different tenses and how they are used in
English.
Present Tense:
Let us begin with the present tense. The present tense is used to
describe actions or events that are happening now or are generally
true. For example:
- I eat lunch at 12 o'clock.
- The sun rises in the east.
- She works as a teacher.
These sentences depict actions or events that occur in the present
or state a general fact.
Simple Past Tense:
Moving on to the past tense, which is used to describe actions or
events that have already happened. The simple past tense is
formed by adding "-ed" to the base form of regular verbs or using
