单元语法聚焦五现在进行时&方位介词(短语)一、现在进行时1. What is he doing? 他正在做什么？2. She is making a salad. 她正在做沙拉。3. They are painting.他们正在画画。以上句子的时态均为现在进行时。下面我们一起学习一下它的构成、用法及句式吧。1定义表示说话时或现阶段正在进行的动作或存在的状态。2句式结构(以do为例)肯定句主语be(am/is/are)v.ing其他例如：He is doing his homework now. 现在他正在做他的家庭作业。否定句主语be(am/is/are)notv.ing其他例如：He isnt doing his homework now. 现在他没有做他的家庭作业。一般疑问句Be(Am/Is/Are)主语v.ing其他？例如：Is he doing his homework now? 现在他正在做他的家庭作业吗？特殊疑问句特殊疑问词be(am/is/are)主语v.ing其他？例如：What is he doing now? 现在他正在做什么？3.现在进行时的使用场合(1)当句中出现时间状语now, these days, at the moment(此刻，现在)等时。例如：Danny is watching TV in his room now. 现在丹尼正在他的房间里看电视。(2)当句中出现look, listen等暗示词时。例如：Look！Tom is drawing a picture on the blackboard.看！ 汤姆正在黑板上画画。(3)根据上下文的提示。例如：Where is Danny? 丹尼在哪儿？He is listening to music in his room.他正在房间里听音乐。4用法(1)表示现在正在进行的动作。例如：I am doing my homework now.现在我正在做我的家庭作业。(2)表示当前一段时期正在进行的动作。例如：We are working in Beijing these days.这些天我们在北京工作。(3)现在进行时除表示现在外，还可以表示将来。现在进行时表示将来时，常有“意图”、“安排”或“打算”的含义。现在进行时常表示最近或较近的将来，所用动词多是位移动词，如： go, come, leave, start等。例如：Im coming.我就来。 When are you starting? 你什么时候动身？Where are we going first？我们先去哪儿？5动词的现在分词由“动词原形ing”构成，规则如下表：词尾变化举例一般情况直接加inglooklookingtrytryingwatchwatching以不发音的字母e结尾的词，去e，再加ingwritewritingdancedancingmakemaking 以一个辅音字母结尾的重读闭音节词，先双写词尾的辅音字母，再加ingbeginbeginningswimswimmingrunrunningsitsittingputputting记忆口诀想把进行句式变，几句口诀记心间。否定句式最简单，be后只把not添；一般疑问be提前，人称也要仔细看；特殊问句特殊记，疑问词应放在最前；紧跟一般疑问句，分词形式记心间。二、方位介词(短语)1. The picture is above the bed. 图画在床的上方。2The chair is in front of the desk.椅子在课桌的前面。3. The ball is under the chair. 球在椅子下面。以上句子中都含有方位介词(短语)，你知道这些常见介词(短语)的用法吗？方位介词(短语)是表示方位的介词(短语)，它表示物体或人的位置。1. in意为“在里”，表示某一物体在另一物体的里面。例如：An English book is in his bag.他的包里有一本英语书。2. above意为“在上方”，表示某一物体在另一物体的上方，两物体不接触，也不一定在正上方。例如：Some pictures are above the TV set. 电视机上方有一些图片。3. under意为“在下面”，指某一物体在另一物体的正下方。例如：A ball is under the chair. 椅子下面有一个球。4. beside意为“在旁边”。例如：Marys sitting beside me. 玛丽正坐在我的旁边。5. in front of意为“在前边”，指在物体外部的前面。例如：There is a big tree in front of our classroom.在我们教室前面有一棵大树。6. on意为“在上”，指在物体表面上，并与其接触。例如：There is a book on the desk. 书桌上有一本书。7. behind意为“在后面”。例如：Theres a garden behind the house. 房子后面有一个花园。 记忆口诀方位介词(短语)的用法里面、上面in和on, over, under上、下方；in front of 前，behind后，at是在某点上；来自from，朝前to，里面穿过是through；表面穿过across，到上面onto进into；在旁边beside，在附近near；唱歌难也易，课后还需认真记。.写出下列动词的现在分词1carry _2.talk_3do_ 4.have_5dance_ 6.write_7set_ 8.sit_9put_ 10.lie_.根据句意及汉语提示完成句子1.
