②Thepanwasonfire!平底锅着火了！例:①Drygrasscatchesfirequicklyinsummer.夏天干草很快就会着火。​②Theoldbarncaughtfirelastnight.昨晚那个旧谷仓着火了。2)onfire“着火;起火”，

介词短语，表“处于着火的状态”，

常与be动词连用(beonfire)。​不可说“becatchingfire”(因“catchfire”是瞬间动作)。【对应练习】1.烟花着火后爆炸了。Thefireworks_____________andexploded.​2.看！营火正燃着，别靠太近。Look!Thecampfireis________.Don'tgettooclose.caughtfireonfirePoint6Thenheturnedonthestoveandlefttheoiltoheatwhilehepreparedthechicken.然后他打开炉子，让油加热着，同时准备鸡肉。—Mom,mayIturnonthecomputer/turnthecomputeron?妈妈，我可以打开电脑吗?—Yes.Ifyoufinishyourhomework,youcanturniton.可以。你如果完成了家庭作业，就可以打开它。turnon接通(电流、煤气、水等)；打开

为“动词+副词”型短语。人称代词作宾语时，要放在turn与on之间turnon“接通(电流、煤气等);打开”.反义词是“turnoff关闭”。宾语是名词时,可放中间,如:turnthelighton或turnonthelight。宾语是代词时,必须放中间,如：turniton,不能说turnonit。​例:①Pleaseturnontheradio.②TheTVistooloud—turnitdown,please.【对点练习】1.天黑了，能把灯打开吗？It'sdark.Canyou__________thelamp?​2.暖气是凉的，你忘开了吗？Theheateriscold.Didyouforgetto___________?turnon

turnitonPoint7由“happy(adj.

快乐的)变y为i+-ly”构成，常用作状语。Look!Thevisitorsarerowingaboathappilyonthelake.看！游客们正在湖上愉快地划船。“Guesswhat,”Allencalledouthappily.“Wewon!”“你猜怎么着。”艾伦高兴地喊道，“我们赢了！”拓happyadj.快乐的happiness

n.快乐，幸福happily

adv.快乐地；高兴地happily/ˈhæpɪli/adv.快乐地；高兴地Allenwasabouttodosowhenhestoppedshort.艾伦正要这么做，却突然停住了。(教材P161b)Thetrainisabouttoleave.火车马上就要开了。WewerejustabouttoleavewhenJerryarrived.我们正要离开，这时杰里来了。beabouttodosth.即将/正要做某事表示即将发生的动作，不可与表示将来的时间状语连用，但可与when构成“beabouttodo...when...”句型，表示“刚要做某事，这时……”。Point8Suddenly,theysmeltsmokeandfoundthepanwasonfire.突然，他们闻到了烟味，发现平底锅着火了。(教材P171d)smoke/sməʊk/n.烟

v.吸烟；冒烟(1)[不可数名词](燃烧产生的)烟Wherethereissmoke,thereisfire.无火不生烟/无风不起浪。Point9(2)[动词]吸(烟)；抽(烟)Hehasagoodlivinghabit.Heneithersmokesnordrinks.他生活习惯很好，既不抽烟也不喝酒。(3)[动词]冒烟Thatoldcarsmokeswhenyoustartitup.那辆旧车启动时会冒烟。Luckily,wecanuseAIforgoodideasnow.幸运的是，我们现在可以用人工智能来想出好主意。

Luckily,Jameswasnotbadlyhurt.幸运的是，詹姆斯伤得不重。luckily/ˈlʌkɪli/adv.幸运地常位于句首修饰整个句子。Point10反义词lucky

adj.幸运的luckn.运气反义词luckily

adv.幸运地unlucky

adj.不幸的unluckily

adv.不幸地拓展“so...that”意为“如此……以至于……”，引导结果状语从句。so后接形容词或副词。Thebookissointerestingthateveryoneofuswantstoreadit.这本书如此有趣，以至于我们每个人都想看。Buthewassoclosetothepanthataflamejumpedontohisshirt.但他离锅太近了，以至于火焰蹿到了他的衬衫上。Point11归纳

与“so...that”相关的常考点：①含“so...that”的复合句可以与“too...to...”和“not...enoughto...”转换。ThestoneissoheavythatIcan’tcarryit.=Thestoneistooheavyformetocarry.=Thestoneisnotlightenoughformetocarry.这块石头太重了，我搬不动。②“such...that”也可表示“如此……以至于……”，但such后接名词。6.Itwasluckythathisshirtwasn’ttoothin!

幸好他的衬衫不太薄。句中的It是形式主语，它指代的是后面thathisshirtwasn’ttoothin这件事。thathisshirtwasn’ttoothin是一个由that引导的主语从句，它是整个句子的真正主语，说明“幸运”具体是什么事情。Itwassostrangethatheleftwithoutsayinggoodbye.他没打招呼就走了，真是太奇怪了。Itisluckythatwehaveanumbrellawithustoday!幸好我们今天带了伞！Point11Itwastheirfirsttimeliving

awayfromtheirfamiliesfamilies,andtheyenjoyedlearninghowtodomanythingsthemselves.这是他们第一次离开家人独立生活，他们很享受学习许多事情的过程。itis/wassomeone’sfirsttime（in）doingsth是固定句型，用来表示“这是某人第一次做某事”。ItishisfirsttimevisitingZhengzhou.这是他第一次游览郑州。Point11enjoy是动词，意为“享受；喜爱”，其后接动词时，要用其动词-ing形式。Mybrotherenjoysreadingbooks.

我弟弟喜欢看书。howtodomanythings

themselves是“疑问词+动词不定式”结构。疑问词可以是how、what、when、where等。Youhavetoconsiderwhattodonext.

你必须考虑下一步该做什么。Whatshouldwedotokeepourselvessafe

fromharm?我们应该做些什么来保护自己免受伤害？Point11harmn.&v.“伤害;损害”。1)名词(不可数)：常与“do”搭配,doharmto...“对……有害”。​2)动词(及物)：直接接宾语,harmsb./sth.“伤害某人/某物”。​派生词：harmful（形容词，有害的）。​例：​①Smokingdoesgreatharmtoyourlungs.吸烟对你的肺危害很大。​②Loudmusiccanharmyourhearing.吵闹的音乐可能损害你的听力。【对点练习】​1.伤害小动物是不对的。It'swrongto_______smallanimals.2.吃太多糖对你的牙齿有害。Toomuchsugardoes_______toyourteeth.harmharm一、根据句意及汉语提示完成句子1.Don’t____（油煎）thebeeffortoolong,oritwillbecomedry.2.Weshould________（扔）
