few、little、a、few、a、little的区别及用法

few、little、a、few、a、little的区别及用法

Unit 5 few, a few, little, a little 等的用法虽然都表示“少”,但(1)few, a few是可数的, little, a little是不可数的。

(2)a few, a little含肯定意味,few, little含否定意味。

这里所谓的“肯定意味”和“否定意味”应该这样来理解:同样是半杯水,口渴者会认为:There is little water in the glass. 而不口渴的人则会认为:There is a little water in the glass.1.few修饰可数名词复数。

2.few (= not many; hardly any)含否定意义;a few (= some; several;a smallnumber of) 含肯定意义。

3.not a few = no few = quite a few = a good few = many。

4.当few受every, last, past, next, some, very等词所修饰时,表示肯定意义,few之前不再有冠词。

如:In the last few minutes, he checked up his paper again.It took us some few days to repair the machine.They are very few in number.There were too few of them.He goes to see his grandma every few weeks.5.在非正式文体中很少见,一般用或代替,如:Only a few people attended the meeting.另外,little / a littleLittle remains to be done about it. (作主语)A little remains to be done.Please give me a little. (作宾语)He knows a little of everything.There is very / but little time left.

千里之行,始于足下。

few、little、a、few、a、little的区分及用法Few, little, a few, and a little are all words that are used to indicate a small quantity or amount. However, they have subtle differences in meaning and usage. Let's take a closer look at each of them:1. Few: Few is used with countable nouns and refers to a small number of things or people. It suggests a scarcity or insufficiency. For example:- There are few apples left in the basket.- Few people attended the meeting yesterday.2. Little: Little is used with uncountable nouns and refers to a small amount or quantity. It indicates a lack or shortage. For example:- There is little milk left in the bottle.- She has little time to finish her work.3. A few: A few is used with countable nouns and means a small number of things or people. It suggests that the quantity is still sufficient or satisfactory. For example:- I have a few friends coming over for dinner.- There are a few books on the shelf.第1页/共3页锲而不舍,金石可镂。

由于φrp与φrs不同,金属表面的反射将改变入
射光的偏振态。
若入射光为线偏振光,其振动面与入射面间有一定 的夹角,则由于反射光的s分量和p分量之间有一个
相位差Δφ=φrp-φrs,而使反射光变成椭圆偏振光。
对于椭圆偏振光的参数进行测量,可以确定出金属
材料的复折射率n,也可求出ε、μ、 σ等物质常数。

1.3.1 光波在金属中的传播
设金属是一种介电常数为ε、磁导率为μ,电导率为σ的 均匀各向同性介质,则物质方程中的J=σE必须予以考
虑。
由麦克斯韦方程,可得金属中光波所满足的波动方程为
不同金属自由电子密度越大(电导率越大),反射本领越大。 同一种金属,入射光频率(波长)不同, 反射率也不同。频率较低的
红外线主要对金属中的自由电子发生作用,而频率较高的可见光和 紫外光可对金属中的束缚电子发生作用。

1.3.3 金属表面反射的频率特性
电子理论的观点,电导率起 因于金属中有密度很大的自 由电子(约1022/cm3)。
当光照射到清洁磨光的金属 表面时,自由电子将在光场 的作用下强迫振动,产生次 波,这些次波构成了很强的 反射波和较弱的透射波,透 射波将很快地被吸收掉。

22-不定代词few,a few,little,a little

22-不定代词few,a few,little,a little

不定代词few, a few, little, a little重/难点重点:了解并掌握few, a few, little, a little的词性、意义和用法。

难点:在语言实践中学会正确运用few, a few, little, a little。

重/难点分析重点分析:a few和few用作不定代词,指代可数名词;a few与few 还可以用作形容词,后面接可数名词复数;a few意为“有一些”,few意为“几乎没有”。

little和a little用作不定代词,指代不可数名词;a little 还可以用作副词,修饰形容词、副词、动词或比较级,意思是“有一点儿”;a little与little用作形容词,后面接不可数名词;a little意为“有一些”,little意为“几乎没有”。

难点分析:不定代词little和a little也可以用作其他意义;few和a few修饰可数名词,但是意义不同;little和a little修饰不可数名词,但是意义也不同。

由于规则较多,学习和运用过程中容易出现错误。

因此,在语言实践中学会正确运用不定代词few, a few, little, a little是学习的难点。

突破策略1. 在导入阶段,教师可以设计视频导入的形式。

一方面,可以使学生在动态、真实的语境中迅速接触到所要学习的语法内容,另一方面,可以调动学生的学习兴趣,使学生的注意力迅速集中到课堂上来。

比如,教师可以选用动画片《疯狂动物城》中含有台词“We know. And we're just a little excited for you, but terrified.”的视频片段。

视频中的台词发音清晰、语速适中,适合初中学生提高听力。

视频播放完毕,教师指出:台词中的a little意为“有点”,此处用作副词,还常常用作不定代词。

接下来一起来学习不定代词few, a few, little和a little的词性、意义和用法。

few、little、a、few、a、little的区别及用法

few、little、a、few、a、little的区别及用法

千里之行,始于足下。

few、little、a、few、a、little的区别及用

1. few: 用于修饰可数名词,表示数量少,意思是几乎没有。

例如:I
have few friends.(我几乎没有朋友。


2. little: 用于修饰不可数名词,表示数量少,意思是几乎没有。

例如:There is little milk left.(剩下的牛奶很少。


3. a few: 用于修饰可数名词,表示数量不多,意思是有一些。

例如:I have a few books.(我有一些书。


4. a little: 用于修饰不可数名词,表示数量不多,意思是有一些。

例如:There is a little sugar left.(剩下一些糖。


区别在于few和little都表示数量少,几乎没有,强调数量的缺乏;而a few和a little表示数量不多,有一些,强调数量的存在。

另外要注意,few
和little都是否定的意思,而a few和a little则是肯定的意思。
