1. We have been finding the bones of tigers

and bears in the caves and we think these

were their most dangerous enemies.

2. We have been excavating layers of ash

almost six meters thick, which suggests

that they might have kept the fire burning

all winter.

3. Yes, indeed, as the botanical analyses

have been specifically showing us, all the

fields around here used to be part of a large

shallow lake.

T: What is the same structure in these

sentences?

Let 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.

3.Read, answer questions

the them learn to practice

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

Practice 4.Sum up and what

do

exercise 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”.

the We

learnt this lesson.

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 5.Do smell the smoke on the person. Using this exercise.

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. the

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 1. S1: Sam has just finished learning to fly an airplane on six-month course. (How long)

S2: How long have you been learning to fly an airplane, Sam? 2. S1: He swam till he felt very tired.

He has just stepped out of the swimming pool. (How along)

S2: How long has he been swimming in the swimming pool? 3. S1: Sally and Zhou Xin have been busy all day. (What)

S2: What have Sally and Zhou Xin been doing all day? 4. S1: They have argued each other for years about the best way to grow potatoes.

(What)

S2: About what have you been arguing with each other for years? 5. S1: Jail Yang uses a particular kind of

washing powder and his clothes have always been clean and soft.

(What)

S2: What kind of washing powder have you been using to make your clothes clean and soft, Jail Yang? used in its passive form.

Step Ⅳ Consolidation Show these exercises on the screen. Step Ⅴ Practice Ask the students to work in pairs, and take turns to read the statement and turn it into a question using the present perfect continuous tense.
