教学课件 北师大英语七年级上册 Starter Section 8 & Section 10语法专项 词性识别与名词复数 全解精讲+分层练习 1 学习目标 1.掌握7类常见词性的定义、功能及判断方法 2.能准确识别单词词性,结合语境理解其作用 3.熟记名词复数5大变化规则,包括特殊情况 4.能正确写出名词复数形式,适配句子语境 5.综合运用词性判断和名词复数知识完成多样练习 词性-核心定义与作用 词性是根据单词在句子中的功能和意义划分的类别 不同词性承担不同语法角色,决定单词在句中的位置 正确识别词性能帮助理解句子结构,避免用词错误 例:动词表示动作,名词表示人或事物,形容词修饰名词 词性是英语学习的基础,贯穿词汇、句式、阅读等所有环节 常见词性(一)-动词与代词 动词(v.):表示动作或状态,是句子的核心成分 例:I live in a small town.(live表示“居住”,动作) 例:We have a library.(have表示“拥有”,状态) 代词(pron.):代替名词或名词短语,避免重复 例:We have a cinema.(we代替“我和同伴们”) 例:I learn a lot from her.(her代替某个女性) 常见词性(二)-名词与形容词 名词(n.):表示人、事物、地点或抽象概念 例:We have a cinema, a library, two hospitals.(表地点/事物) 例:Life is easy here.(life表抽象概念“生活”) 形容词(adj.):修饰名词或代词,描述性质/特征 例:Life is easy here.(easy修饰life,表“轻松的”) 例:Her class is so interesting.(interesting修饰class,表“有趣的”) 常见词性(三)-连词、介词与副词 连词(conj.):连接词、短语或句子,表逻辑关系 例:One supermarket is on my left, and the cinema is next to it.(and表并列) 介词(prep.):表示名词与其他词的关系(时间/地点等) 例:The library is on the right of my home.(on表位置) 例:I go there after school.(after表时间) 副词(adv.):修饰动词、形容词等,表程度/频率等 例:I often go there to read.(often修饰动词go,表频率) 例:Her class is so interesting.(so修饰形容词,表程度) 词性判断-核心技巧 1.看功能:作谓语→动词;作主语/宾语→名词;修饰名词→形容词 2.看标志:ly结尾多为副词(如often虽无ly,表频率也是副词) 3.看搭配:介词后接名词;连词连接两个并列成分 4.看语境:结合句子意思判断,如“easy”在“Life is easy”中修饰名词 例:判断“have”:I have a book.(作谓语,动词) 例:判断“interesting”:an interesting book(修饰名词,形容词) 词性-易错点提醒 1.词性混淆:将副词当形容词用,如quick(adj.)vs quickly(adv.) 2.介词与连词混淆:and是连词(连接句子),on是介词(表位置) 3.代词指代错误:用he代替女性,her代替男性 4.名词与动词混淆:如“work”(n.工作/ v.工作),需结合语境判断 5.形容词位置错误:修饰名词时需放在名词前(除系动词后) 小练习(一)-判断单词词性 判断下列单词的词性,填写对应的缩写(v./pron./n./adj./conj./prep./adv.) 1.live ___________ 2. we ___________ 3. cinema ___________ 4.easy ___________ 5. and ___________ 6. on ___________ 7.often ___________ 8. interesting ___________ 9. after ___________ 10.tell ___________ v. pron. n. adj. conj. prep. adv. adj. prep. v. 名词复数-核心定义与功能 名词复数表示两个或两个以上的人、事物或地点 单数名词表“一个”,复数名词表“多个”,是数量表达的关键 例:a desk(一张书桌)→ many desks(很多书桌) 例:one man(一个男人)→ three men(三个男人) 名词复数的正确使用,能确保数量表达的准确性 名词复数变化规则(一)一般情况 规则1:一般情况直接在词尾加-s 例:chair → chairs,desk → desks,teacher → teachers 例句:There are many desks and chairs in the classroom. 规则特点:适用范围最广,大部分普通名词均遵循 注意:加-s后发音有变化,清辅音后读/s/,浊辅音后读/z/ 例:books /bʊks/(清辅音),bags /bæɡz/(浊辅音) 名词复数变化规则(二)-s/x/ch/sh结尾 规则2:以s, x, ch, sh结尾的名词,词尾加-es 例:class → classes,box → boxes,watch → watches 例:brush → brushes,dish → dishes 例句:I like all the classes. She has three boxes. 记忆技巧:这类单词词尾发音多为“嘶”“嗤”音,加-es更顺口 注意:es发音为/ɪz/,如classes /ˈklɑːsɪz/ 名词复数变化规则(三)-辅音+y结尾 规则3:以“辅音字母 + y”结尾的名词,变y为i再加-es 例:dictionary → dictionaries,family → families,story → stories 例句:There are many dictionaries on the shelf. 注意:区分“辅音+y”与“元音+y”:元音+y直接加-s 例:boy → boys(o是元音),toy → toys(o是元音) 记忆口诀:辅音加y,变i加es;元音加y,直接加s 名词复数变化规则(四)-f/fe结尾 规则4:以f或fe结尾的名词,变f/fe为v再加-es 例:shelf → shelves,knife → knives,wife → wives 例句:The shelves are full of books. She has two knives. 特殊情况:部分f结尾名词直接加-s(拓展) 例:roof → roofs,gulf → gulfs(这类词较少,特殊记忆) 记忆口诀:妻(wife)拿小刀(knife),架(shelf)上找树叶(leaf),变f为v再加es 名词复数变化规则(五)-不规则变化 规则5:不规则变化需单独记忆,无固定规律 常见例子:man → men,woman → women,child → children 例:The men are teachers. Those children are students. 其他常见不规则变化(拓展): foot → feet,tooth → teeth,mouse → mice 这类单词使用频率高,需重点背诵记忆 名词复数-易错点提醒 1.漏加/es:class → classs(正确:classes),box → boxs(正确:boxes) 2.辅音+y变y为i错误:story → storys(正确:stories) 3.f/fe变v错误:knife → knifes(正确:knives) 4.不规则变化混淆:child → childs(正确:children) 5.元音+y错误变化:boy → boyes(正确:boys) 6.不可数名词误用复数:water → waters(water表“水”不可数,无复数) 小练习(二)-写出名词复数形式 根据变化规则,写出下列名词的复数形式 1.class ___________ 2. box ___________ 3. dictionary ___________ 4.shelf ___________ 5. story ___________ 6. teacher ___________ 7.child ___________ 8. man ___________ 9. knife ___________ 10.boy ___________ classes dictionaries shelves stories teachers children men knives boys boxes 综合练习(一)-单项选择 1.“live” in “I live in a town” is a ___________.
