现在进行时的用法

主语在句首，am/is/are跟着走。现在分词随其后，其他成分不可丢。表示动作正进行，句中now把时间定。一般问句如何变，把be提到主语前。否定式更简单，be后只把not添。句中提问v-ing，what和be放句首。现在进行时的使用场合(1)当句中有时间状语如now,rightnow,atthe/thismoment等时，句子表示现在正在发生的事。Linda’sbrotheriswatchingTVinhisbedroomnow.现在琳达的哥哥正在他的卧室里看电视。Whatareourparentsdoingatthemoment?我们的父母此刻在干什么呢？(2)当句中有thesedays,thisweek,thismonth,thisterm等时间状语，且句子要表达现阶段正在进行的动作。Thesedayswearehelpingthefarmersworkonthefarm.这些天我们在农场帮农民们干活。Tomiswritingabookthisweek.这一周汤姆在写一本书。(3)句中出现“Look!”“Listen!”

“Bequiet!”

等时，说明后面的动作正在发生，应用现在进行时。Listen!OurEnglishteacherissingingthepopularEnglishsong.听！我们的英语老师正在唱那首流行的英文歌曲。Bequiet!Thebabyissleeping.安静！这个婴儿正在睡觉。(4)语境暗示句子用现在进行时。—WhereisMrWang?王先生在哪里？—Heisreadinganewspaperintheoffice.他正在办公室里看报。Observethischart.SimplePresentTensePresentProgressiveTenseIoftenwatchTV.IamwatchingTVnow.SheoftenwatchesTV.SheiswatchingTVnow.TheyoftenwatchTV.TheyarewatchingTVnow.DoyouoftenwatchTV?AreyouwatchingTVnow?SimplePresentTensePresentProgressiveTenseIoftenwatchTV.IamwatchingTVnow.SheoftenwatchesTV.SheiswatchingTVnow.TheyoftenwatchTV.TheyarewatchingTVnow.DoyouoftenwatchTV?AreyouwatchingTVnow?左栏例句中谓语部分的结构与右栏例句的谓语结构有何不同?左栏的谓语动词为do/does(动词原形/动词第三人称单数)；右栏的谓语动词为be(am/is/are)+v-ing。SimplePresentTensePresentProgressiveTenseIoftenwatchTV.IamwatchingTVnow.SheoftenwatchesTV.SheiswatchingTVnow.TheyoftenwatchTV.TheyarewatchingTVnow.DoyouoftenwatchTV?AreyouwatchingTVnow?两栏例句中各使用的时间状语有何不同?左栏的时间状语为often；右栏的时间状语为now。SimplePresentTensePresentProgressiveTenseIoftenwatchTV.IamwatchingTVnow.SheoftenwatchesTV.SheiswatchingTVnow.TheyoftenwatchTV.TheyarewatchingTVnow.DoyouoftenwatchTV?AreyouwatchingTVnow?这两栏例句各表达什么概念？左栏的一般现在时表示现在的状态，经常的或习惯性的动作；右栏的现在进行时表示现在正在进行或发生的动作。3aWritesentencesfollowingtheexamples.1.Jenny/cleanthehouse/now______________________________2.Bob/makedinner/everySaturday______________________________Jennyiscleaningthehousenow.BobmakesdinnereverySaturday.n.房子3.Mary’sparents/drink
