T: In Junior Books, we learnt some tenses. Now look at some sentences on the screen and find out what tense is used in each of them.
(Teacher shows the sentences on the screen.) 1. We get up at six every morning.
2. I will return you the book as soon as possible. 3. I lost my wallet at the theatre.

(Teacher asks some students to say the tenses in other sentences in the same way and then gives the answers.)

6. the Past Continuous Tense 7. the Present Perfect Tense
8. the Past Perfect Tense(in the object clause)
T: OK. Now look at the form on the screen and compare the forms and usages of the tenses.
Step Ⅲ.Discussion
T: From the form, we can see the present continuous tense expresses an action going on at the moment of speaking or in the present period. The present indefinite tense expresses an habitual actions. Look at the examples on the screen. He is watching TV now.
Professor Wang is attending a meeting in Paris these days. He gets up at 6 o’clock every morning. T: Do they have other uses?
S3:Yes.The adverbs “always, constantly, continually” can be used with the present continuous tense to express a repeated action with an emotional suggestion. The present indefinite tense can express a general truth.
T: Very good. Can you give me some examples? S4:Of course,…
(Teacher shows some examples on the screen.) She is always working hard like that.(praise)
You are always forgetting the important things.(criticism) Light travels more quickly than sound.
T: We can also use the two tenses to express future actions, especially in sentences with verbs of motion, such as, go, come, start, leave and so on. But you must pay attention to the difference between them. Please look at the sentences on the blackboard. 1. We are leaving on Friday.
2. My train leaves at 3 o’clock this afternoon. In the first sentence, the present continuous tense is used for a definite future arrangement. The time is nearly always given and is usually in the immediate future. But when we express a fixed future action, we should use the present indefinite tense. Are you clear about that? Ss: Yes.
T: Are there any other tense or sentence structures for future action?
S5:Yes,The future indefinite tense expresses future action. But it expresses the future action without intention. We often use “be going to” to express the subject’s intention to perform a certain future action.
e.g. You will feel better tomorrow morning. I’m going to be a teacher when I grow up.
I’m going to meet Tom at the station at 6 o’clock. (=I’m meeting Tom at the station at 6 o’clock.) (Teacher writes the examples on the blackboard.)
T: Wonderful. We can also use other structures to express future action, such as “be about to +v.” and “be to+ v.” “be about to +v.” expresses the very immediate future. When it is used, it can’t be followed by the adverbial of time .“be to+v.” expresses a command or a plan. Look at the example on the blackboard.
