语法点 1:“数词+连字符+名词(单数)+连字符+形容词”构成的
复合形容词
该结构专门构成复合形容词,核心功能是修饰名词,主要用于说明人的“年龄
特征”。
例子:Harry is a 12-year-old boy.(12-year-old是复合形容词,修饰名词boy,
说明Harry的年龄特征为12岁);My cousin is an 8-year-old student.(8-year-
old修饰student,说明表妹8岁的年龄特点)。
语法点2:elderly的用法
1. 作形容词(adj.)
含义为“年老的、上了年纪的”,用法灵活,常作定语(直接修饰名词),也
可作表语(跟在be动词后面)。
• 作定语例子:She volunteers to help elderly neighbors every weekend.
(elderly修饰名词neighbors,意为“上了年纪的邻居”)
• 作表语例子:The grandma living next door is elderly but very energetic.
(elderly跟在be动词is后作表语,意为“年老的”)
2. 作名词(n.)
含义为“老年人”,特指这一群体,常用固定结构 the elderly(“the + 形容
词”表一类人),注意不可加s,也不能用a/an修饰。
例子:Our community organizes activities for the elderly every month.(the
elderly指代“老年人”群体,无复数形式,不用an修饰);
We should offer seats to the elderly on the bus.语法点3:other/others/the other/the others/another的用法
1. other
• 词性:形容词
• 搭配要求:后面必须接名词(可接单数或复数)
• 指代特点:泛指“其他的”,无明确范围限制
例子:I need to buy other notebooks for school.(接名词复数notebooks,泛
指“其他的笔记本”);
Do you have other ideas about the trip?(接名词单数ideas,泛指“其他的想
法”)
2. others
• 词性:代词
• 搭配要求:后面不接名词
• 指代特点:泛指“其他部分/其他人”,相当于“other + 名词复数”
例子:Some students are cleaning the classroom, others are watering the
flowers.(others不接名词,指代“其他学生”,相当于other students)
3. the other
• 词性:可作形容词或代词
• 搭配要求:作形容词时接名词,作代词时单独使用
• 指代特点:特指(有明确范围),常表示“两者中的另一个”
例子:I have two pencils, one is black, the other is yellow.(作代词,特指两
者中的“另一个铅笔”);
Give the cake to the other child in the room.(作形容词,接名词child,特指
房间里“另一个孩子”)
4. the others
• 词性:代词
• 搭配要求:后面不接名词
• 指代特点:特指“剩余全部”,相当于“the other + 名词复数”
例子:There are 30 students in our class, 10 are boys, the others are girls.
(the others指代“剩余的全部学生”,相当于the other students)
5. another
• 词性:可作形容词或代词
• 搭配要求:作形容词时接名词单数,作代词时单独使用
• 指代特点:泛指“三者或三者以上的另一个/再一个”
例子:Can you pass me another pen?(作形容词,接名词单数pen,泛指“再
一支笔”);
This story is interesting, please tell me another.(作代词,泛指“另一个故
事”)
语法点4:elderly与elder的核心区别
两者均有形容词(adj.)和名词(n.)词性,但核心用法差异明显:
• elderly:语气礼貌且正式,作形容词时表“年老的”,可修饰人;作名词时
用“the elderly”表“老年人”群体。
例子:Elderly citizens can get free tickets here.(形容词,礼貌表“年老的市民”);
The elderly enjoy morning exercises in the park.(名词,表“老年人”群体)
• elder:语气通用且偏口语,作形容词时仅用于比较,表“年长的”(常指家
人,如兄弟姐妹),不修饰物;作名词时可指“年长的人”。
例子:My elder brother studies in a university.(形容词,指“年长的哥哥”
家人范畴);
We should learn from the elder in the village.(名词,指“村里的长辈”)
语法点 5 不同词性(形容词、名词、动词)在句子中承担的成分
(定语、谓语、宾语、主语)
一、主语:句子的“陈述对象”(谁/什么)
• 名词作主语(初中核心):直接充当陈述对象
例:The book is interesting.(book是名词,作主语,表“陈述的对象是书”)
• 动词的动名词(v.-ing)作主语(初中拓展):表“动作本身”
例:Reading is good for us.(reading是动词read的动名词,作主语,表“阅
读这个动作”)
二、谓语:句子的“动作/状态”(做什么/是什么)
只能由动词担任(初中核心考点),分两类:
1. 实义动词作谓语(表具体动作)
例:He runs every day.(runs是实义动词,作谓语,表“跑步”的动作)
2. 系动词作谓语(表状态/特征)+ 表语
例:She is happy.(is是系动词,作谓语;happy是表语,表“状态”)
三、宾语:动作的“对象/承受者”(动作作用于谁/什么)
• 名词作宾语(初中核心):作动词的动作对象
例:I like music.(music是名词,作like的宾语,表“喜欢的对象是音乐”)
• 动词的非谓语形式(不定式/动名词)作宾语(初中拓展):
例:She wants to read.(to read是动词read的不定式,作want的宾语);
He enjoys swimming.(swimming是动名词,作enjoy的宾语)
四、定语:修饰“名词/代词”的成分(什么样的)
• 形容词作定语(初中核心):放在名词前,说明名词的“特征/状态”
例:a beautiful flower(beautiful是形容词,修饰flower,表“漂亮的花”)
• 名词作定语(初中常考):放在名词前,说明名词的“属性/用途”
例:a school bag(school是名词,修饰bag,表“学校用的包”)
• 动词的分词(现在分词/过去分词)作定语(初中高频):
例:a missing child(missing是现在分词,作定语,表“失踪的孩子”);
the broken cup(broken是过去分词,作定语,表“破碎的杯子”)
语法点6
一、核心用法:since(接“时间点”,表“从该点开始持续到现在”)
“时间点”指过去某个具体的时刻、事件或句子,翻译为“自从……以来”。
1. 接具体时间点(年/月/日/时分/)
○ He has lived here since 2018.(自从2018年以来,他一直住在这里。)
○ We have known each other since last Monday.(自从上周以来,我们就认识了。)
2. 接“过去时间的事件”(名词短语)
○ She hasn’t eaten anything since breakfast.(自从早餐后,她就没吃过东
西。)
○ They have been busy since the meeting.(自从会议开始后,他们就一直很
忙。)
3. 接“一般过去时的从句”(表过去某个动作发生时)
○ He has improved his English since he started studying with a tutor.
(自从他跟家教学习后,英语就一直在进步。)
二、核心用法:for(接“时间段”,表“动作持续了多久”)
“时间段”指具体的时长(几天/几小时/几年等),翻译为“持续了……”。
• 接“数字+时间单位”(天/周/月/年/小时等),时间单位可省略(口语中常
见)。
○ We have studied this subject for three months.(我们学习这门课已经3个
月了。)
三、关键易考点(必记)
1. “since+时间段+ago”的特殊结构:相当于“for+时间段”,需注意“ago”
体现过去时间点。
○ He has lived here since three years ago. = He has lived here for three
years.(他在这里住了3年了。)
