语法解析:
A.The present perfect tense 现在完成时
1.现在完成时的构成
现在完成时由“助动词have/has+动词的过去分词”构成。
1). 表⽰过去发⽣或已经发⽣的某⼀动作对现在造成的影响或结果,强调的是现在的状况(表⽰“已完成”) 。常⽤的时间状语有:already, yet, now, just(刚刚), by this time, so far(迄今为⽌), by now(到现在为⽌)如:
Have you finished today?s work yet? 你已经完成今天的⼯作了吗?
2). 表⽰开始于过去并持续到现在的动作或状态,也可能还会持续下去(表⽰“未完成”)往往和包括现在在内的表⽰⼀段时间的状语连⽤,常⽤的时间状语有: all day, the whole day, up to now(直到现在), all one?s life(⼀⽣), so far(到⽬前为⽌), in the
past/last few years(在最近⼏年⾥), recently, already, just, lately, ,,yet等。表⽰持续动作状态的动词多是延续性动词。
I have been in the library for a whole morning.
我已经在图书馆呆了整整⼀个上午了。
3). 现在完成时还可以⽤来表⽰过去的⼀个时间到现在这段时间内重复发⽣的动作。
We have had four texts this semester.
这学期我们已经学了四篇课⽂。
4). 现在完成时的常⽤副词
现在完成时常与recently(最近), already(已经,⽤于肯定句), never(从不,⽤于否定句), ever(曾经,⽤于肯定句和疑问句),
just(刚刚), before(以前), yet(已经;仍然,⽤于疑问句和否定句), since(⾃从) 等副词连⽤。
Have you ever washed the dishes? 你洗过碗吗?
B.形容词⽐较级
1.⼀般句式的构成:A + is / are+形容词⽐较级+ than + B
例:She is taller than me.
她⽐我⾼。
2.英语形容词⽐较级的构成
英语形容词⽐较等级有三个:原级,⽐较级和最⾼级。形容词⽐较等级形式变化有规则的和不规则的两种。
1). 规则变化
(1)单⾳节词末尾加-er(⽐较级),-est(最⾼级)
例:原级⽐较级最⾼级great greater greatest
(2)单⾳节如以e结尾,只加-r(⽐较级),-st(最⾼级)
例:原级⽐较级最⾼级fine finer finest
(3)闭⾳节单⾳节词如末尾只有⼀个辅⾳字母,须先双写这个辅⾳字母,再加-er(⽐较级),-est(最⾼级)
例:原级⽐较级最⾼级big bigger biggest
(4)少数以-y,-er,ow,-ble结尾的双⾳节词,末尾加-er(⽐较级),-est(最⾼级)。以-y结尾的词,如-y前是辅⾳字母,则变y为-i,再加-er和-est。以-e结尾的词只加-r和-st。
例:原级⽐较级最⾼级clever cleverer cleverest
(5)其它双⾳节和多⾳节词皆在前⾯加单词more和the most。
例:原级⽐较级最⾼级careful more careful the most careful
2). 不规则变化
例:原级⽐较级最⾼级bad worse worst
注:有些形容词⼀般没有⽐较等级。如:right, wrong, woolen等。
1). 原级(同级)⽐较:as...as...; not as (so)...as...
例:We?ll give you as much help as we can.
我们会尽可能多的给你提供帮助.
2). ⽐较级:表⽰两者之间⽐……更……;可⽤状语much, a little, even等修饰
例:He is even richer than I.
他甚⾄⽐我更富有.
3). 最⾼级:形容词最⾼级前必须加the, 副词最⾼级前常省略the,后⾯多⽤of...;in...短语表⽰范围:
例:It was the most/least interesting story I have ever listened.
这是我曾听到的最有趣/最⽆趣的故事。
4). 如果在两者之间表⽰“最……”时要在⽐较级前加the
例:John is the clever of the two boys. 这两个男孩中约翰最聪明。
C.be going to 的⽤法
1. be going to 是⼀种固定结构,它后⾯要接动词原形,⽤来表⽰按计划或安排要发⽣的动作,有时也可以表⽰推测将要或肯定会发⽣的动作,有“准备;打算”的意思。含有be going to 结构的句⼦中往往有表⽰将来的时间状语。
例:We are going to have a class meeting this afternoon.
今天下午我们打算开班会。(安排)
Look at the black clouds. It?s going to rain.
看那些乌云,快要下⾬了。(推测)
2. be going to 在肯定句中的形式
be going to 结构中的助动词be很少⽤原形,它⼀般有三种形式,即:am , is , are 。当主语是I时⽤am ;当主语是第三⼈称单数时⽤is;当主语是其他⼈称时⽤are。
例:I am going to buy something tomorrow morning.
明天早上我要去买些东西。
She is going to see Mr. Wang this afternoon.
她打算今天下午去看望王先⽣。
3. 使⽤be going to结构应注意的两点
1). There be 句型的be going to 结构为:There is / are going (注意句型中going to 后⾯的be不能改为have) 常⽤来表⽰将有某事发⽣。
例:There is going to be a football match next Saturday in our school.
下周六我们学校将有⼀场⾜球⽐赛。
2). come, go, leave, arrive等表⽰位置移动的动词常⽤现在进⾏时表⽰将要发⽣的动作,它们很少与be going to 结构连⽤。
例:Miss Sun is coming tonight. 今晚孙⼩要来。
D.特殊疑问句句型
1. 特殊疑问句的含义
以特殊疑问词开头,对句中某⼀成分提问的句⼦叫特殊疑问句。常⽤的疑问词有:
what,who,whose,which,when,where,how,why等。
2. 特殊疑问句有两种语序:
1). 如疑问词作主语或主语的定语,即对主语或主语的定语提问,其语序是陈述句的语序:例:Who is singing in the room? 谁正在房间⾥唱歌?
Whose bike is broken? 谁的车⼦坏了?
疑问词+be/助动词/情态动词+主语+谓语】
例:What does she like? 她长什么样⼦?
What class are you in? 你在哪个班级?
Where are you from? 你从哪⾥来?
How do you know? 你怎么知道的?
What time does he get up every morning?
他每天早晨⼏点起床?
E.名词副词修饰的位置关系
1. 作定语时的位置:⼀般要放在所修饰的名词之后。
The weather tomorrow will be fine. 明天的天⽓晴朗。
2. 修饰形容词时的位置:⼀般放在被修饰的词之前。
She looks quite young. 她看上去很年轻。
但副词enough却要放在所修饰的形容词或副词之后。
You?re old enough to go to school. 你够上学的年龄了。
3. 修饰动词时的位置:有以下⼏种不同情况:
1). 频度副词通常放在⾏为动词前⾯,或者be动词、情态动词或助动词后⾯。
He always gets up early. 他总是起得很早。
2). 表⽰确定时间的副词,通常放于句未,也可围起置于句⾸。
I saw him yesterday. 或Yesterday I saw him. 我昨天看见了他。
3). 表⽰地点的副词常放在句未。
comparisonsMr. Li was born here. 李先⽣是在这⾥出⽣的。
4). 表⽰⽅式的副词常放在句未,也可放在其它位置,但通常不放在动词与宾语之间。He closed the door quietly. 他轻轻地关上门。
