She knew that in those years she was making her parents proud.3. Instead of crying about what she had lost, Sang Lan thought about what she could do to get better.4. By the time she competed in the New York Goodwill Games, she had been a dedicated junior gymnast for eleven years.T: First, look at the four sentences. Do they have something in common?S: Yes! They all use the past tense. T: But there are also differences among them. Can you tell the differences? Next, discuss with your partners. Pay attention to the italic words.Several minutes later.T: Can you show your opinions now?Ss: Yes.S: In the first sentence we use the simple past tense to talk about something happened in the past.T: Very good. What about the second sentence? S: I think it means something happened in the past and continued for some time.T: Very good! Thank you! Now lets move to the last two sentences. S: They are both used in the past perfect tense. By looking at the two sentences, I think we use the past perfect tense to talk about things that happened in the past and stopped before another past action began.T: Excellent! But I think you are partly right. Do the two sentences express the same meaning? S: The fourth sentence means the thing happened in the past and at that time another past action began.T: Thats it! Just now we talked about different forms of the past tense. And later, we will do more practice about them. Now lets move to the future tense. Please look at the following sentences.

In sentences1, 2, 3 the simple future tense is used. When the subject is the first person, we usually use shall instead of will.T: You are right. Then when shall we use “be going to”?S: I think when we want to talk about future plans and intentions, we can use “be going to”.T: Very good. You got the answer. What about sentence 4?S: Sentence 4 uses the future continuous tense. This sentence is used to talk about something that will start in the future and continue for some time.T: Excellent! The fifth sentence is used in the future in the past. When shall we use this tense?S: When we want to talk about an event which was in the future at the time when it was discussed.
