用于一般现在时的副词，除了上面提到的一些表示频率的以外，常见的还有：now, today , nowadays等等。

其句式变化可分为两种情况 1)表示动作，一般人称作主语的，变否定句须在动词前加助动词don’t；变一般疑问句须在句首加助动词do。

E.g. They have lunch at 12:00. They don’t have lunch at 12:00. Do they have lunch at 12:00 2）单三人称做主语的，变否定句须在动词前加助动词doesn’t；变一般疑问句须在句首加助动词does.含有be动词的要在be上做变化.E.g. Jenny speaks English very well. E.g. Danny is a good student.Jenny doesn’t speak English very well.Danny isn’t a good student.Does Jenny speak English very well? Is Danny a good student?自我检测：(一)、单选1 Jenny ____ in an office. Her parents ____in a hospital.A work; worksB works; workC work; are workingD is working; work2 One of the boys_____ a black hat.A haveB there isC there areD has3 We will go shopping if it____ tomorrow.A don't rain Bdidn't rain Cdoesn't rain Disn't rain4 He said the sun ____in the east and ____in the west.A rose; setB rises; setsC rises, setD rise; sets5 Wang Mei ____ music and often ____ to music.A like; listenB likes; listensC like; are listeningD liking ; listen6 Jenny____ English every evening.A has studyB studiesC studyD studied(二)、填空1 I can take Li Ming there when he _____ ( come) to visit.2 _____your sister_____(know)English?3Her home____ _____ ______(远离 )her school.4The pot_____(not look) like yours very much.5 Where _____you____(have)lunch every day?6 Who_____(想要 )to go swimming?7 ______she_____(do) the housework every day?8 Jenny and Danny usually______(play) games in the afternoon .二、单三人称形式易出错例：1 He—— (play) football very well. 2 Danny——(go) to school at 7:10.三、在句式变换时易出错例：1 Does Jenny has (has) a good friend? 2 Brian doesn’t live s (not live) in China.四、对do的理解易出错例：We——(not do) our homework in the afternoon.do是一个比较难理解的词，它有三个含义: a)是所有行为动词的总称；b)是助动词，无实义；c)是一个具体的行为动词“做，干”。

此句中给出的do指“做，干”，not指把此句变为否定句，故须在do前加助动词don’t。

五、对主语的数判断有误例： Li Ming with me——(be) in Beijing.现在进行时1、现在（说话的瞬间）正在进行或发生的动作，强调“此时此刻”。

E.g. He is reading . They are talking now.2、当前一段时间内的活动或现阶段正在进行的动作。

E.g. They are working these days.现在进行时主要表现在位于动词的变化形式上，即一般采用be+-ing形式表示。

见课本重读闭音节即两个辅音中间夹一个元音.如:sit---sitting begin---beginning(重读在gin这个音节上，相当与把gin该成双写的)3、某些动词的现在进行时，表预定的计划或即将发生的动作。

E.g I am coming.（一）单选1、 Look! He _____their mother do the housework.A. is helpingB. are helpC. is helpD.is helpping2 、_____are the boys doing They are singing in the room.A .WhoB .How C.What D.Where3、Don’t talk here.

Look! She ____(wear)a red sweater today.1、lie（vi.）“躺，卧” 时2、lie 做（vi.）“说谎” 时：lie→lay→lain→lying lie→lied→lied→lying1 、The students are singing in the room.(对划线部分提问)现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它”改错Are the children running or jump?一般将来时be going to do sth表达自己打算做某事、计划做某事或者有意做某事She is going to buy a coat this afternoon.表示未来的事实或对将来的预测，可以用“will+动词原形”There will be a computer on every desk in the future.将来每张课桌上都会有一台计算机will + 动词原形(will可以用于任何人称) 需要注意的是当主语是第一人称时will可以换成shall,特别是在以I或we作主语的问句中,一般用shall. e.g. Shall we go to the zoo?第一种结构的句式变化是: 变否定句在will后边加not.，缩写为won’t 变一般疑问句把will提前. e.g. She will be back in three days. She will not be back in three days. Will She be back in three days第二种结构的句式变化要在be上做文章. E.g. They are going to clean their classroom. They are not going to clean their classroom.
