Pleasemakerules.LanguagepointsTherearetoomanyrules!1)thereare表示“有”。Therebe是英语中常用句型，意思是“有”，表示“人或事物的存在”。Therebe

后面的名词是句子的主语，属倒装结构。要表达“某个地方或某个时间存在什么食物或人”的时候常用“Therebe+名词+地点(时间)

”这一句型。have和therebe:have与therebe

都有“有”的意思。①have用来表示各种关系的“所有”,身上“具有(说明人物的外观)”和整体与局部的“含有”。如:Ihaveagoodfriend.我有一位好朋友。Hasthebookaredcover?这本书的封面是红色的吗?

动词have是个用法较活的词,表示“有”,第三人称单数形式是has。在英国英语中,have意为“拥有”。构成疑问句时把have提到主语前面,表示否定时,在其后面加not,可缩写为haven’t。如：--Haveyouapen?你有钢笔吗?--Yes,Ihave.ButIhaven’tanewone.

是的,我有。但我没有新钢笔。在美国英语中,除上述用法外,还可以用助动词do/does

来构成疑问句和否定句。如:--Doyouhaveakite?你有风筝吗?--Yes,Ido.我有。Hedoesn’thaveanything.他没有任何东西。

②therebe表示存在的关系,表示某处有某人或某物时常用这种句型。如：Therearetwobikesunderthetree.树下有两辆自行车。Therearefortystudentsinourclass.我们班有四十名学生。③当表示整体与局部的“含有”时或者是难以判断“有”是所属关系还是存在关系时,have和therebe均可使用。如表示“一年有十二个月”:Ayearhastwelvemonths．Therearetwelvemonthsinayear.注意:在therebe结构中,如果主语不止一个,谓语动词往往和与之最接近的主语在数上保持一致,即我们常说的就近原则。如:Thereisapen,twopencilsandfourbooksonthedesk.桌子上有一支钢笔,两支铅笔和四本书。Therearetwomapsandapictureonthewall.墙上有两张地图和一幅画。2)toomanyrules“太多的规定”,其中toomany

用来修饰可数名词rules。如:Hehastoomanyfriendstomeet.他有很多朋友要见。修饰不可数名词时,要用toomuch如:Wehavetoomuchworktodo.我们有许多工作要做。2.AndIhaveto

gotobedbefore10:00.十点钟前我就得上床睡觉。1)gotobed“去睡觉”。如:Whattimedoyouusuallygotobed?你一般几点睡觉？2)before在此句中为介词,意思是notlaterthan“最迟在……”。如:I’llbebackbefore6o’clock.我最迟六点钟回来。3.Afterdinner,Ican’trelaxeither.晚饭后我也不能放松。副词either表示“也”，用于否定句末，用法与表示肯定或陈述的副词too相似，可用逗号与语句的主题隔开。如：

YoulikeEnglish.Ilikeit,too.

你喜欢英语，我也喜欢。Myfathercan’tspeakEnglish.Mymothercan’t(speakit),either.我爸爸不会讲英语，我妈妈也不会。课时重点回顾Reviewtoomanyrules,getupatsixo’clockeverymorning,leavethedirtydishesinthekitchen,can’tplaybasketballafterschool,havetodoone’shomework,watchTV,onweekends,can’trelaxeither,readabook,runtoschool,don’teatinclass,makeone’sbed,WhatcanIdo?注:另附word文档。点击此处链接下列各句中均有一处错误，请找出并改正。1.Ihavetoinbedby10:00everynight.___________2.Thechildrenneverhavesomefunatschool.____________3.Simoncan’tgooutatschoolnights.__________4.I’mbusytoday.Thereistoomanywork._____________5.Youcan’thavetowearyouruniformathome.__________________can’t改为don’tin前面加besome改为anyat改为onmany改为much根据汉语提示补全英语句子
