Step ⅠGreeting

Step Ⅱ Lead-in Ask the students to look at some pictures and point out the sentences that contain the structure as in Sample sentences: 1.My younger brother has been accessing the net. 2. The baby has been sleeping for 1 hour. 3. They have been playing basketball all the day. 4. The boy has been reading a book for almost

4 hours.

5.He has been talking with his girlfriend. 6.The telephone has been ringing for almost a minute.

T: What is the same structure in these sentences? S: “have/ has been doing...”

T: Yes, in this unit, we will learn “have/has been doing sth.” That is the present perfect continuous tense.

Step Ⅲ Explanation Present Perfect Continuous [HAS / HAVE] + [BEEN] + [V+ing] 1, 叙述某一动作从过去开始一直继续到现在仍在继续之中或刚刚停止。经常与for, since, all morning/day/week用在一起。

Examples: 1) You have been studying for four straight hours. Why don’t you take a break? 2) The telephone has been ringing for almost a minute. Why doesn’t someone answer it? 2, 叙述从过去某时开始一直继续到现在，但不再继续下去的事情。－－带有浓厚的感情色彩，强调持续了“那么久”或做得“那么辛苦”

1) Oh, you have come at last! I have been waiting for you for two long hours.(我等了你足足两个小时) 2) You are here! I have been looking for you long.（我找了你老半天）

3, 叙述“最近”一直从事的工作或活动。－－lately, recently 4, 叙述从过去某时到现在，或最近，一再重复的动作。

1) I have been knocking. I don’t think anybody’s in.(我一直在敲门。我想没人在里面。) 2) I have been writing letters since breakfast.(我从早餐起就一直在写信)

Note: When you are using a verb tense with more than one part such as Present Perfect Continuous (has been studying), adverbs often come between the first part and the second part (has only been studying).

Use 1 Duration from the Past until Now

T: We use the Present Perfect Continuous to show that something started in the past and has continued up until now. “for five minutes”, “for two weeks”, and “since Tuesday” are all durations which can be used with the Present Perfect Continuous. Look at the following examples.

Show the following.

They have been talking for the last hour. She has been working at that company for three years. James has been teaching at the University since June. Use 2 Recently, Lately

T: You can use the Present Perfect Continuous without a duration such as “for five minutes”, “for two

weeks”, and “since Tuesday”. Without the durations, the tense gives a more general meaning of “lately”. We often use the words “lately” or “recently” in

the sentence to strengthen this meaning. Now read these examples.

Show the following.

Recently, I have been feeling really tired. She has been watching too much television lately. Mary has been feeling a little depressed. Important

T: Remember that the Present Perfect Continuous has the meaning of “lately” or “recently.” If the Present

Perfect Continuous is used in a question such as “Have you been feeling alright?”, it suggests that the person looks sick or unhealthy. A question such as “Have you been smoking?” suggests that you can smell the smoke on the person. Using this tense in a question suggests you can see, smell, hear, or feel the results of the action. It is possible to insult someone by using this tense incorrectly. Important: Non-Continuous Verbs / Mixed Verbs T: It is important to remember that Non-Continuous Verbs cannot be used in any continuous tenses. Also,

certain non-continuous meanings for Mixed Verbs cannot be used in continuous tenses. To express the idea of Present Perfect Continuous with these exception verbs, you must use Present Perfect. Here are some examples.

Show the following.

Sam has been having his car for two years. (Not Correct) Sam has had his car for two years. (Correct) Active / Passive Present Perfect Continuous Examples: Recently, John has been doing the work. (Active)

Recently, work has been being done by John. (Passive) Note: Present Perfect Continuous is rarely used in its passive form.
