我是我们班跳得最远的。
二. 句子成分
1.主语:句子所陈述的对象。
2.谓语:主语发出的动作。一般是有动作意义的动词。
3. 宾语:分为动词宾语和介词宾语,属于动作的承受者。
4. 系动词:表示状态或状态变化的动词,没有实际的动作意义。如 be, 感官系动词(look, sound, smell, taste 和 feel)、保持类系动词(keep, stay 和 remain)、状态变化类系动词(become、get、turn 和 go)等。
5. 表语:紧跟系动词后面的成分。
6. 定语:修饰名词或代词的成分。
7. 状语: 修饰形容词、副词、动词或句子的成分。
8. 补语:分为宾语补足语和主语补足语。是对宾语和主语的补充说明,与其有主动或被动的逻辑关系。
例如:You should keep the room clean and tidy.
你应该让屋子保持干净整洁。
(You是主语, should keep是谓语,the room是宾语,clean and tidy是宾语补足语。)
This kind of food tastes delicious.
这种食物吃起来很可口。
(This kind of food是主语, tastes是系动词, delicious是表语。)
注意:主语、谓语、宾语、系动词、表语、补语是一个句子的主干成分;定语和状语是一个句子的修饰性成分,不是主干成分。
三. 句子类型
1. 简单句的基本形式是由一个主语加一个谓语构成。
2. 复合句由一个主句和一个或一个以上的从句构成。
3. 两个或两个以上的简单句用并列连词连在一起构成的句子,叫做并列句,其基本结构是“简单句+并列连词+简单句”。
四. 简单句的五种基本句型
1.“主语 + 谓语”(即“主谓”句型)
例:They arrived in Harbin yesterday morning.
分析:“they”(主语)“arrived”(谓语)。
2.“主语 + 谓语 + 宾语”(即“主谓宾”句型)
例:I study English.
分析:“I”(主语)“study”(谓语动作)“English”(宾语即动作涉及的对象)。
3.“主语 + 谓语 + 间接宾语 + 直接宾语”(即“主谓双宾”句型)
例:Our teacher taught us English.
分析:“our teacher”(主语)“教”(谓语动作)“us”(间接宾语)“English”(直接宾语)。
4.“主语 + 谓语 + 宾语 + 宾语补足语”(即“主谓宾宾补”句型)
例: He asked her to go there.
分析:“he”(主语)“asked”(谓语动作)“her”(宾语即动作涉及的对象)“to go there”(补语—补充说明宾语做什么)。
5.“主语 + 系动词+ 表语”(即“主系表”句型)
常用的系动词有be, keep,lie, remain, stand, become, fall, get, go, grow, turn, look, feel, seem, smell, sound, taste, 等。
例: I am a teacher. 我是一名老师
分析:“I”(主语)“am”(系动词)“a teacher”(表语—即表明主语的身份)。
五. 宾语从句
1. 宾语从句的含义
在主句中做宾语的从句叫做宾语从句。
如:She knew that the teacher had seen the film.
她知道这位老师看过这部电影。
“that the teacher had seen the film”做 knew 的宾语,同时又是由连接词 that 引导的从句,所以它叫做宾语从句。
2. 宾语从句的分类
(1)动词宾语从句:顾名思义,它是位于动词后面的宾语从句。
如:He asked whose handwriting was the best in our class.他问我们班上谁的书法最好。
(2)介词宾语从句:顾名思义,它是位于介词后面的宾语从句。
如:I agree with what you said just now.我同意你刚才说的话。
(3)形容词宾语从句:顾名思义,它是位于形容词后面的宾语从句。
如:I am afraid that I will be late. 恐怕我要迟到了。
3. 引导名词性从句的连接词
(1)that:没有含义,在宾语从句中不做成分
(2)whether/if:表示是否,在宾语从句中不做成分。
I don't know if /whether he still lives here after so many years. 我不知道这么多年后,他是否还住在这里。
(3)连接代词:what, which, who, whom, whose(在宾语从句中做主、宾、表和定语)
连接副词:where, when, how, why(在宾语从句中做状语)
The small children don't know what is in their stockings.(what 在宾语从句中做主语)
这些小孩子不知道什么在他们的长筒袜里。
Could you tell me why you were late for the meeting this morning?(why 在宾语从句中做原因状语)
你能告诉我为什么你今天早上开会迟到吗?
4. 在做宾语从句的题目时应注意两点
(1)时态:
①当主句是现在时态时,宾语从句可以根据需要使用任何时态。
I don't know when he will come back.我不知道他将何时回来。
He tells me that his sister came back yesterday.他告诉我他姐姐昨天回来了。
②当主句是过去时态时,宾语从句必须是一种过去的时态。
She asked me if I knew whose pen it was.她问我是否知道这是谁的钢笔。
He said that he could finish his work before supper.他说他会在晚饭前完成工作。
③当表示客观事实或普遍真理的句子做宾语从句时,任何时候都用一般现在时。
The teacher said that the earth goes round the sun.老师说过地球绕着太阳转。
(2)语序:任何从句都使用陈述句语序,宾语从句当然也不例外。
八年级英语重点知识点总结
重点句型:
一、 have fun doing sth.
【句型介绍】 意为"做某事有乐趣",其中have fun 相当于enjoy oneself,表示过得愉快。
1. 英语中的集体名词,如family, class, team等作主语时,若作为一个整体看,其后的谓语动词用单数;若强调其组成成员,谓语动词用复数。如:
My family is a happy one. 我家是个幸福的家庭。
My family are all watching TV. 我们全家人都在看电视。
2. 在比较级中,要注意than后面人称代词的格。
1)当句子中的谓语动词是不及物动词时,than后面的代词用主格还是宾格,在意思上通常没有区别。如:
He runs faster than I / me. 他跑得比我快。
They get to school earlier than we / us every day. 他们每天都比我们到校早。
2)当句中的谓语动词是及物动词时,than后面的人称代词用主格还是宾格在意思上就有差别了。试比较:
I like you more than he. (=I like you more than he likes you.) 我比他更喜欢你。
I like you more than him. (=I like you more than I like him.) 你和他相比,我更喜欢你。
二、 But I don't know what to do.

My question is when to leave for Tokyo. 我的问题是什么时候去东京。
三、 This is ... speaking.
【句型介绍】 该句为打电话用语,用来进行自我介绍,This代表我,speaking可以省去。
Hello! This is Tom (speaking). 你好,我是汤姆。
