微点拨　（1）要牢记现在进行时的主动语态、被动语态的基本构成。（2）现在进行时除表示“目前/现在正在发生或进行的动作”这一含义之外，还可以与频度副词连用，表示某种感情色彩。（3）现在进行时与表示短暂性的动词g，cme，leave，start，begin，see ff等连用时，可表示将来的含义。
现在进行时的被动语态一、现在进行时的被动语态的含义现在进行时的被动语态表示“某人/事此时此刻正在被……”，主语是动作的承受者。The task is being dne by three f them in the ffice nw.这项任务正在被他们三个人在办公室里做。
二、现在进行时的被动语态的构成现在进行时的被动语态的构成：am/is/are＋being＋过去分词。它的否定形式是把nt放在第一个助动词am/is/are之后，即：am/is/are＋nt＋being＋过去分词。一般疑问句的形式是把第一个助动词放在句首，句末改为问号，即Am/Is/Are＋主语＋being＋过去分词？特殊疑问句的形式是把特殊疑问词放在一般疑问句的前面。❶Bks are nt being read by the students in Class 8.八班的学生们没有读书。❷Are bks being read by the students in Class 8?八班的学生们正在读书吗？❸What is being dne by the students in Class 8？八班的学生们正在做什么呢？
三、主动语态变为被动语态1．“三变”：原句主语变为by的宾语，宾语变为主语，谓语由主动变为被动。2．“三不变”：句意不变，原句时态不变，原句主谓宾以外的成分不变。The little girl is reading an interesting strybk in the living rm.→An interesting strybk is being read by the little girl in the living rm.这个小女孩正在起居室里读一本有趣的故事书。
四、现在进行时的被动语态的基本用法1．表示现在正在进行的被动动作❶Martin is being interviewed nw by the reprter.马丁现在正在被一个记者采访。❷What I want t tell yu is that ur car is being repaired nw in the garage.我想告诉你的是我们的汽车现在正在修理厂被修理。2．表示现阶段正在进行的被动动作❶A paper is being written by me these days.这些天我正在写一篇论文。❷The life f the panda is being studied at present.现在正在研究熊猫的生活环境。
