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] Examples: I have been waiting here for two hours.WWW.ziyuanku.com$来&源：ziyuanku.com She has only been studying English for two years. 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.
