Unit5Understandingideas知识点讲练2-外研版英语八年级上册

20252026学年外研版英语（2024）八年级上册Unit5Understandingideas知识点讲练★Knowledgepoints1.Theyread“Pleasebequiet”,“Nosmellyfood”and“Pleaselookafteryourchildren”.它们写着“请保持安静”“请勿食用有异味的食物”和“请照看好你的孩子”。(1)read意为“（文字、标识等）写着；内容是”，强调标识、通知等上面的文字信息，主语通常是“标识、牌子、信件”等。read的原形，过去式同形。例如：Thesignreads“Noparking”.牌子上写着“禁止停车”。(2)lookafter意为“照顾；照料”，侧重“日常照料、照顾起居”，可接人或物。例如：Mydutyistolookafteranimals.我的责任就是照看这动物。carefor,lookafter,takecare,takecareof这四个词组在英语中经常被使用，它们都有“照顾”、“关心”的含义，但具体用法和含义有所不同：carefor照顾；关心；喜欢。lookafter照料；照顾；照管；（尤其作为工作）料理，打理。takecare保重；当心；留心。takecareof处理；应对；照顾；看看；看护。takecareof与lookafter基本同义，更强调“负责任地照料”，可接具体事务（如工作、任务）。【学以致用】当妈妈忙的时候，你应该照顾你的弟弟。____________________________________________________________(2)告示牌上写着“禁止吸烟”。____________________________________________________________2.Everyoneknowstherules,Ithought.Theyaren’tjustonthewallbutalsoinourmindsandhearts.我想，每个人都知道这些规则。它们不仅仅在墙上，还在我们的脑海和心中。notjust…butalso…意为“不仅……而且……”，用于连接两个并列的成分，可以连接名词、动词、形容词等。当连接两个并列主语时，谓语动词的形式遵循“就近原则”，即与butalso后面的名词在人称和数上保持一致。例如，NotjustTombutalsohisparentslikewatchingmovies.不仅汤姆，而且他的父母也喜欢看电影。like与靠近的hisparents在数上保持一致。【学以致用】不仅他，我也对画画感兴趣。____________________________________________________________(2)她不仅会唱歌，还会跳舞。____________________________________________________________3.Andrulesarethereforustofollow!规则存在就是为了让我们去遵守的!followtherules意为“服从规定；遵守规则”，follow有“遵守”的意思。指的是日常、学校、组织等场景的一般性遵守。例如：Followtherulesofthelibrarywhenstudying.学习时遵守图书馆规则。obeytherules遵守规则，强调“服从权威”的正式场景。例如：Soldiersmustobeytherules.士兵必须遵守规则。breaktherules违反规则，描述“违规行为”及后果。例如：Weshouldn’tbreaktherulesofthegame.我们不能违反游戏规则。【学以致用】过马路时我们必须遵守交通规则。____________________________________________________________(2)遵守学校规章制度很重要。____________________________________________________________throat...ly,Ifeltbrave.Itookadeepbreath,stoodupandclearedmythroat...突然间，我感到（我变得）勇敢起来。我深吸一口气，站起身来清了清嗓子……(1)takeabreath意为“吸一口气”，takeadeepbreath即“深吸一口气”。(2)feel,意为“感到……”，系动词，后接形容词作表语。【学以致用】在演讲前，她深吸了一口气使自己镇定下来。____________________________________________________________(2)当我收到礼物时，我感觉非常开心。____________________________________________________________5.However,Ifoundmyfavouriteflowerpotbroken.然而，我发现我最心爱的花盆碎了。found是find的过去式。“find+宾语+宾语补足语”，宾语补足语可以由形容词、现在分词、过去分词、介词短语等充当，用于补充说明宾语的状态、动作等情况。例如：Wefoundhimsleepingintheclassroom.我们发现他正在教室里睡觉。【学以致用】我发现数学题很难。____________________________________________________________(2)他们发现那个男孩正在公园里哭。____________________________________________________________

Grammar动词不定式作目的状语动词不定式作目的状语知识点讲解参考教材131132页内容。一、基本形式：动词不定式的基本形式是to+动词原形，否定形式是在动词不定式前面直接加not。在句中作目的状语时，用来表示谓语动词动作发生的目的。例如：Igetupearlytocatchthefirstbus.我早起是为了赶上第一班公交车。在这个句子中，tocatchthefirstbus就是动词不定式作目的状语，说明了getupearly的目的。二、位置(1)动词不定式作目的状语时，通常位于句末。例如：Hestudieshardtopasstheexam.他努力学习是为了通过考试。(2)为了强调目的，也可以将其置于句首，此时通常用逗号与句子其他部分隔开。例如：ToimprovemyEnglish,IreadEnglishbookseveryday.为了提高我的英语水平，我每天都读英语书。三、与其他结构的转换(1)与inorderto/soasto的转换：inorderto和soasto都有"为了"的意思，后接动词原形，可与动词不定式作目的状语互换。但soasto一般不用于句首。例如：bus.=upearlyinorderto/soastocatchtheearlybus.=Igotupearlytocatchtheearlybus.我早起是为了赶上早班车。(2)与inorderthat/sothat的转换：inorderthat和sothat引导目的状语从句，其后接完整的句子，与动词不定式作目的状语可以相互转换。例如：exam.=dieshardinordertopasstheexam.=Hestudieshardinorderthathecanpasstheexam.他努力学习是为了能通过考试。四、注意事项当动词不定式的逻辑主语与句子的主语不一致时，需要使用动词不定式的复合结构"for+逻辑主语+动词不定式"。例如：TheteachergivesussomeadviceonhowtolearnEnglishwellforustoimproveourEnglish.老师给我们一些关于如何学好英语的建议，以便我们提高英语水平。
