考点 1语法讲解现在进行时考向一表示现在或现阶段正在进行的动作。常用的时间状语有：now，at the moment，right now等。在句首出现look或listen，也可以判断出后面的句子用现在进行时。
eg：She is watching TV now.
她现在正在看电视。
Look！The panda is climbing a tree.
看！那只熊猫正在爬树。典例—Cathy, can you answer the doctor?
I ________the room.
—I'm coming, mum. (安徽)
A．clean B．cleaned
C．have cleaned D．am cleaningD【解析】根据语境可知是正在打扫房间，应用现在进行时，所以选D。考向二come, go, arrive, leave, start, begin, return等动词的现在进行时形式可以表示将要发生的动作。
eg：I’m leaving tomorrow.
明天我就要离开了。考点 2考向一 ①概念：过去发生或已经完成的动作对现在造成的影响或结果，或从过去已经开始，持续到现在的动作或状态。
②时间状语：already，yet，just，ever，never，before，in the past/last few years等。
③构成：助动词have/has＋过去分词。
eg：Have you ever been to Japan?
你曾经去过日本吗？
I have just finished my homework.
我刚刚完成我的家庭作业。现在完成时典例Monica，you ________ the exam！Congratulations！ (河北)
A．pass B．have passed
C．will pass D．are passingB【解析】由后句“祝贺(你)！”可知是已经通过了考试，
表示过去发生的某个动作对现在造成的影响应用现在完成时。故选B。 for＋时间段，since＋时间点，表示
一段时间，应将短暂性动词转变为延续性动词，
表示动作的持续。典例Mike used to be a top student, but he ________behind since he lost himself in computer games. (常州)
A．fell B．has fallen
C．was D．has been【解析】根据时间状语since 引导的从句可知主句应用现在
完成时，B项不能与since连用，所以选D。D考向二【难点】考点 3考向一 表示主语是动作的承受者，即行为动作的对象的一种语态。构成：be＋过去分词。
eg：The book was written by Lu Xun.
这本书是由鲁迅写的。被动语态典例—Wow！You have a ticket to the Expo!
—It ________ by my uncle. He is working in
Shanghai. (安顺)
A．has bought B．had bought
C．is bought D．was boughtD【解析】句意：——哇！你有一张世博会的票！——是我
叔叔买的，他在上海工作。bought的原形是buy，意思是“买”。根据句意可知，这句话中的主语It指代的是上面提
到的ticket，故它和动词buy之间构成被动的关系，因此用
被动语态，排除A和B。根据句意可知，这张票是过去买的，
应该用一般过去时态，故选D。考向二主动语态中，在make，let，hear，see，watch，notice等词后跟省略to的动词不定式，但在被动语态中，to不可省略。
eg：We saw a stranger enter the hall.→
A stranger was seen by us to enter the hall.
我们看到一个陌生人进入了大厅。Fill in the blanks with the correct forms of the verbs in brackets.4aJoe：________ you ever ________ (take) part in?

我想参加你的聚会。考向典例Many young people took part in ________ trees on Tree Planting Day. (白银)
A．planting B．plants
C．to plant D．plant【解析】本题考查动词短语的用法。take part in参加，
其后用动词的-ing形式。故选A。A take part in，join与join in的辨析。
它们皆有“参加”的意思，但用法不同。拓展afford/?'f??(r)d/v.买得起；承担得起(后果)afford常与can (could)/be able to 连用，多用于否定句中，afford to do sth.意为“承担得起做某事”。
eg：I can afford a car.
我可以买得起一辆小汽车。知识点2考向典例The Apple Watch is very beautiful，but it’s too expensive. So I can’t ________it.(酒泉)
