1. To learn to identify Present Continuous Passive.
2. To describe what is happening using Present Continuous Passive.
Look and answer
Q1. What causes the action in sentence (a)? The dress or the wind?
The wind.
a. And just look at how her dress is being folded by the wind!
b. I’m being pushed around quite a bit, in fact.
Q2. What is happening to “me” in sentence (b)?
People around “me” are pushing “me”.
Q3. What is the difference between the two groups of sentences?
passive form
And just look at how her dress is being folded by the wind!
I’m being pushed around quite a bit, in fact.
active form
And just look at how the wind is folding her dress!
People are pushing me around quite a bit, in fact.
Q4. Why does the author choose to use the passive form instead of the active form in the reading passage?
Present continuous passive
1. 結(jié)構(gòu):am/is/are being done
2. 定義：
現(xiàn)在進行時的被動語態(tài)表示說話時或現(xiàn)階段正在進行或發(fā)生的被動動作，強調(diào)主語是動作的承受者。
3. 用法
① 表示此刻正在進行的被動動作。
A new film is being shown in the theater.
② 表示現(xiàn)階段正在進行的被動動作，但此動作不一定在此時此刻發(fā)生。
A modern school is being built in our hometown.
③ 表示經(jīng)常性的被動動作，常和always, often, constantly等詞連用 (表達某種感情色彩)。
He is always being praised by the teacher.
4. 注意
① 注意不可遺漏being
Look! The children are being taken good care of by their aunt.
比較: Children are taken good care of at school.
② 注意不可忽視“現(xiàn)階段”
（可表示目前一階段正在進行的一個被動的動作）
③ 注意沒有現(xiàn)在進行時的被動語態(tài)的動詞
一些表示“狀態(tài)、心理活動、擁有、存在”等的動詞，一般不用現(xiàn)在進行時的被動語態(tài)，而常用一般現(xiàn)在時的被動語態(tài)。
Football is loved by more and more people.
④ 注意“be + under / in等介詞 + 名詞”結(jié)構(gòu)可表示現(xiàn)在進行時的被動語態(tài)的含義。
The problem is under discussio (= is being discussed) at the meeting.
The telephone is in use (= is being used) now.
