【优秀满分范文】

Dear Jenny,

How is your survey on mobile payment going? I’m glad I can help with it.

It is generally believed that China is the largest mobile payment market. Nowhere else is the cashless trend more obvious than in China. Most of us are used to paying by scanning QR codes whatever we buy—books, clothes, and electronic devices, to name a few, which is a glimpse into the life of most Chinese like me and my family.

With the widespread use of mobile payment, Wechat or Alipay is the most convenient and safest way to pay. We rarely need to carry a wallet or cash at all. Besides, never will we worry about getting fake notes or having to count change. In short, mobile payment has greatly changed people"s life in China.

Personally, I think mobile payment should be encouraged. First, it has won over consumers with its convenience. Another advantage is that there are often discounts if you make mobile payment, as major online payment platforms are competing to have more consumers use their service.

I hope my explanation can be of some help to you. Wish you good luck.

Yours faithfully,

Li Hua

热点二:网瘾

【写作要求】

【优秀满分作文】

Dear Jack,

I am glad to hear from you. As your close friend, I’d like to talk about the harm of Internet addiction to you as I feel worried to know that you have wasted lots of valuable time playing the Internet games.

As we know, the Internet is a convenient tool to improve our knowledge and skills. However, our life will be greatly affected if we are addicted to it. For example your grades may go down and your health will be going from bad to worse. To make things worse, it can also damage the relationship with your family. So I think it is high time that you got rid of the bad habit. It is a good idea for you to read some meaningful books and do some physical exercise.

I am looking forward to hearing your good news soon.

Yours,

Li Hua

热点三:拒为低头族

【题目要求】

现在越来越多的人成为低头族(People who can’t help checking their phones all day are known as phubbers. Phubbing trends to involve not only the young people, but also the elderly.),如何引导低头族抬头?你们班举行了以“拒为低头族”为主题的班会。假设你是学生李华,请为班会写一篇100词左右的发言稿。

要点如下:

1. 你周围有低头族吗?他们成为“低头族”的原因。

2. 成为“低头族”给学习和生活带来的影响。

3. 就如何“拒为低头族”提一些建议。

_____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

【优秀满分范文】

Nowadays, we can see many people are watching their mobile phones in subway, restaurants, elevators, roads and so on. There is no denying that people who like the mobile phone are concerned about its attractive functions. Phubbers can’t stop sending messages, surfing the Internet, listening to music and even taking photos by using the mobile phone. Moreover, some people have less time to relax themselves. They make use of the time when they are on the way to school or other places to play mobile games.

However, phubbing disturbs not only our study but also our life. On the one hand, phubbers waste lots of time playing cell phone games and sending messages, particularly in class. Other people also complain they are disturbed when phones ring in classrooms. On the other hand, it can lead to health problems. For instance, using a mobile phone on the sofa can cause back and neck pain.

As far as I am concerned, it is high time that we threw away the phone and raised our heads up. Do cherish everything around us and appreciate the scenery ahead of us. What’s more, we should do more exercises and take part in real-life activities. In a word, only when we use the phone reasonably, can we realize the happiness of life.

热点四:家风(传统文化)

【篇3】高考英语作文命题热点

高考生物命题热点

高考生物命题热点

作者简介:

丁鹏举,河南省漯河高中高级教师,河南省课改优秀教师,全国奥林匹克生物竞赛优秀辅导教师、漯河市优秀教师和优秀班主任。

纵观全国的高考试题,无论是自主命题的省份,还是全国统一命题的省份,生物遗传与变异都是必考内容,一直为高考命题的热点。本文就以20全国各地高考试题为例,对生物遗传与变异这一部分内容进行归纳、分析,以期对考生朋友能有所帮助。考查学生对基本概念、原理的理解能力

(一)选择题:在选择题中,考查对概念理解能力的知识点小,但涉及面广,要求考生能以小见大。

1.(年江苏理综)在有丝分裂和减数分裂的过程中均可产生的变异是(多选)

ADNA复制时发生碱基对的增添、缺失或改变,导致基因突变

B.非同源染色体之间发生自由组合,导致基因重组

C.非同源染色体之间交换一部分片段,导致染色体结构变异

D.着丝点分裂后形成的两条染色体不能移向两极,导致染色体数目变异

本题借助有丝分裂和减数分裂的过程考查生物的变异类型,意在考查考生的分析比较能力。考生必须对基因突变、基因重组、染色体变异的概念和含义充分理解,才能正确解答此题。DNA复制时发生碱基对的增添、缺失或改变,导致基因突变,因有丝分裂和减数分裂间期均存在DNA的复制,故均可发生基因突变,A项正确;非同源染色体自由组合导致非同源染色体上的非等位基因重新组合,即基因重组,只发生在减数第一次分裂后期,B项错误;非同源染色体之间交换一部分片段,在减数分裂和有丝分裂过程中都可以发生,引起的变异为染色体结构变异中的易位,而同源染色体的非姐妹染色单体间交换部分片段则发生在减数分裂过程中,引起基因重组,C项正确;在有丝分裂后期或减数第二次分裂后期,都可能发生着丝点分裂后染色体的分离异常,从而引起染色体数目的变异,D项正确。

【答案】ACD

(二)非选择题:在非选择题中,主要考查对遗传规律的理解。

2.(2011年全国新课标卷)某植物红花和白花这对相对性状同时受多对等位基因控制(如A、a;B、b;C、c……),当个体的基因型中每对等位基因都至少含有一个显性基因时(即ABC……)才开红花,否则开白花。现有甲、乙、丙、丁4个纯合白花品系,相互之间进行杂交,杂交组合组合、后代表现型及其比例如下:

根据杂交结果回答问题:

(1)这种植物花色的遗传符合哪些遗传定律?

(2)本实验中,植物的花色受几对等位基因的控制,为什么?

本题看似很复杂,但只要能理解自由组合定律的实质,利用了自由自由组合定律的实质,做起来很简单。很多考生没有做出第(2)题,原因在于对基因的分离定律和自由组合的实质没有真正理解,对于此题无从下手。根据题干“受多对等位基因控制”这一条件,很容易回答出第(1)小题:(教学论文 )符合基因的自由组合定律。解答第(2)小题时,观察全部杂交实验结果,发现“乙×丙”和“甲×丁”两个杂交组合涵盖甲、乙、丙、丁4个品系,且F2中红色个体占全部个体的比例均为81/(81+175)=81/256=(3/4)4,根据基因的分离定律知,每对基因遗传时,F2中显性个体的比例为3/4,(3/4)4就说明了涉及4对等位基因。

【答案】

(1)基因的自由组合定律和基因的分离定律(或基因的自由组合定律)

(2)4对。本实验的乙×丙和甲×丁两个杂交组合中,F2中红色个体占全部个体的比例81/(81+175)=81/256=(3/4)4,根据n对等位基因自由组合且完全显性时,F2中显性个体的比例为(3/4)n,可判断这两个杂交组合中都涉及到4对等位基因。综合杂交组合的实验结果,可进一步判断乙×丙和甲×丁两个杂交组合中所波及的4对等位基因相同。

复习策略

全面深入理解遗传学相关概念,这不仅是掌握遗传学的基础,也是形成科学思维的正确途径。所谓全面深入理解是指不仅要“知其然”,而且要“知其所以然”。知道概念的涵义,还要知道它们的前因后果、适用条件和范围,以及相关知识之间的联系和区别。能够认识概念和规律的表达形式,定性描述、解释生物学的现象和规律。只有透彻理解的知识,才能记忆牢固,才能纳入到相应的认知结构中随时提取和灵活运用。考查遗传学知识的综合运用

这一部分的试题特别注重在充分理解生物学基本概念和基本原理的基础上,对学生进行能力考查。遗传学知识的综合性强,信息的呈现形式多样,考查方式多样。

(一)遗传与变异在生物育种中的应用

3.(2011年安徽理综)雄家蚕的性染色体为zz,雌家蚕为zw。已知幼蚕体色正常基因(T)与油质透明基因(t)是位于Z染色体上的一对等位基因,结天然绿色茧基因(G)与白色茧基因(g)是位于常染色体上的一对等位基因,T对t,G对g为显性。

(1)现有一杂交组合:ggZTT×GGZ´;W,F1中结天然绿色茧的雄性个体所占比例为_________,F2中幼蚕体色油质透明且结天然绿色茧的雄性个体所占比例为_________。

(2)雄性蚕产丝多,天然绿色蚕丝销路好。现有下列基因型的雌、雄亲本:GGZW、GgZtW、ggTW、GGTW、GG272t、ggZIzt、ggZZGgTT,请设计一个杂交组合,利用幼蚕体色油质透明区别的特点,从F1中选择结天然绿色茧的雄蚕用于生产(用遗传图解和必要的文字表述)。

本题主要考查学生的推理能力和遗传图解的表达能力。知识方面考口zw型性别决定方式。(1)ggTZT×GGTW杂交组合中,子代的基因型有GgTz和GgZrW两种,且比例为1:1,所以Fl中结天然绿色茧的雄性个体(Gg272´;)所占比例为1/2,F2中幼蚕体色油质透明的雌性个体(TW)所占比例为1/4,结天然绿色茧的个体(G_)所占比例为3/4,因此F2中幼蚕体色油质透明且结天然绿色茧的雌性个体所占比例为1/4×3/4-3/16。(2)由于幼蚕无法立即体现将来蚕茧颜色,因此要通过杂交实验间接辨别。根据F1体色性状判断性别,所以杂交后代个体不能全为体色正常或全为油质透明,由此判定选取的亲本性染色体组成为z´;zt或z´;w,此组合符合后代雌性幼蚕个体体色全为油质透明,雄性幼蚕个体全为体色正常的要求。进而用排除法确定雄性亲本基因型为ggZZ或GgZZ,雌性亲本基因型为GG7W。

从孵化出的F1幼蚕中,淘汰体色油质透明的雌家蚕,保留体色正常的雄家蚕用于生产

复习策略

在复习中,一是应强调对高中生物学核心概念和基本原理的深入理解,做到概念清晰并且准确把握他们的含义和适用条件,能结合问题情境中给出的条件做出分析、推理和判断;二是应注重理论联系实际,联系生活和生产实际;三是注重学科内知识运用的综合能力、知识迁移能力的训练;四是应拓展相应知识面,提高分析问题的能力;五是应注意专业术语的使用,提高书面表达的能力。

遗传与育种的知识综合性很强,需要在复习中对比分析,遗传育种中对育种年限的问题也要引起重视。例如一般认为单倍体育种的优点是缩短育种年限,容易形成思维定势。要根据培育的具体对象而定的。在培育显性性状的的纯合子时有优势,但如果培育的是隐性性状的品种时,它与杂交育种相比就没有优势。

(二)遗传方式的推断和概率计算

4.(2011年浙江理综)以下为某家族甲病(设基因为B、b)和乙病(设基因为D、d)的遗传家系图,其中Ⅱ,不携带乙病的致病基因。

请回答:

(1)甲病的遗传方式为____,乙病的遗传方式为____。I1的基因型是____。

(2)在仅考虑乙病的情况下,III2与一男性为双亲,生育了一个患乙病的女孩。若这对夫妇再生育,请子女的可能情况,用遗传图解表示。

(3)B基因可编码瘦素蛋白。转录时,首先与B基因启动部位结合的酶是____。B基因刚转录出来的RNA全长有4500个碱基,而翻译成的瘦素蛋白是由107个氦氢酸组成,说明____。翻译是,一个核糖体从起始密码子到达终止密码子约需4秒钟,实际上合成100个瘦素蛋白分子所需的时间约为1分钟,其原因是____。若B基因中编码第105位精氨酸的CCT突变成ACT,翻译就此终止,由此推断,mRNA上的____为终止密码了。

本题考查对遗传方式的判断。只要掌握住判断方法,做起来难度不大。(1)对该遗传家系图进行分析:由于Ⅲ;患甲病,且其父亲与母亲均表现正常,所以可知该病由隐性致病基因引起。若为伴X染色体隐性遗传,则其父亲的基因型应为XbY,表现型应为患病,而其父表现型正常,所以甲病的遗传方式应为常染色体隐性遗传;由于Ⅲ1、Ⅲ3患乙病,且其父母对于乙病均表现正常,可知乙病为隐性遗传病,若乙病为常染色体隐性遗传,则Ⅲ1、Ⅲ3的基因型应为dd,可推知II1的基因型为Dd,由于题中所给信息Ⅱ1不携带乙病致病基因,所以假设不成立,则乙病的遗传方式为伴X染色体隐性遗传。通过对遗传家系图的分析,I2的基因型为bbXY,112的基因型为bbXDX,II3的基因型为BbXDY,可推知I1的基因型为BbXDX_。(2)Ⅲ:与其丈夫所生女孩患乙病,该女孩基因型为XdXd。综合(1)分析,可知该夫妇的基因型为XDXd、XY。(3)转录开始时,RNA聚合酶识别启动子并与之结合。一个密码子由mRNA上3个相邻碱基构成,则瘦素蛋白对应的碱基数目为167×3=501个,而刚转录出来的RNA全长为4500个碱基,远远大于501,则说明真核生物的基因是不连续的,中间存在内含子,转录出mRMA后,经加工剪接后才能进行翻译;翻译过程中若一个mRNA结合一个核糖体,那么合成100个瘦素蛋白分子所需时间为100X4秒=400秒,实际所需时间约为1分钟,说明在翻译时,一个mRNA分子上可以相继结合多个核糖体,所以短时间内就可以合成出多个蛋白质分子。B基因中编码105位精氨酸对应的碱基为GCT,则对应的密码子为CGA,突变为ACT后对应的密码子变为UGA,翻译就此终止,由此可知UGA为终止密码子。

(3)RNA聚合酶转录出来的RNA需要加工才能翻译一条mRNA上有多个核糖体同时转录UGA

复习策略

遗传方式的判断也是高考常考的内容之一,是高中生物学习的难点、重点,一定要掌握。复习过程中要注意理解不同伴性遗传类型的特点,掌握判断遗传系谱图的方法,并将遗传规律与伴性遗传、人类遗传病等知识进行有机结合,以强化逻辑思维能力、比较分析能力和概率计算能力。

(三)遗传规律相关的实验设计

5.(2011年山东理综)荠菜的果实形状有三角形和卵圆形两种,该形状的遗传涉及两对等位基因,分别用A、a和B、b表示。为探究荠菜果实形状的遗传规律,进行了杂交实验(如图)。

(1)图中亲本基因型为________。根据F2表现型比例判断,荠菜果实形状的遗传遵循________。F1测交后代的表现型及比例为____。另选两种基因型的亲本杂交,F1和F2的性状表现及比例与图中结果相同,推断亲本基因型为________。

(2)图中F2三角形果实荠菜中,部分个体无论自交多少代,其后代表现型仍然为三角形果实,这样的个体在F三角形果实荠菜中的比例,为________;还有部分个体自交后发生性状分离,它们的基因型是____。

(3)荠菜果实形状的相关基因a.b分别由基因A、B突变形成,基因A、B也可以突变成其他多种形式的等位基因,这体现了基因突变具有______________的特点。自然选择可积累适应环境的突变,使种群的基因频率发生____________,导致生物进化。

(4)现有3包基因型分别为AABB、AaBB、和aaBB的荠菜种子,由于标签丢失而无法区分。根据以上遗传规律,请设计实验方案确定每包种子的.基因型。有已知性状(三角形果和卵圆形果实)的荠菜种子可供选用。

实验步骤:

①____________;

②____________;

③____________。

结果预测:

I如果____________,则包内种子基因型为AABB;

II如果____________,则包内种子基因型为AaBB;

Ⅲ如果____________,则包内种子基因型为aaBB。

【解析】

(1)由题意可知:荠菜的一对相对性状由两对等位基因控制,又因为F1只有三角形果实,所以三角形是显性性状,基因型为A-B-,卵圆形是隐性性状,基因型为aabb。从F2的表现型来看,F2的表现型比例接近15:1,是9:3:3:1的变形,故遵循自由组合定律。符合这一规律的亲本的基因型组合有两种,分别是AABB×aabb和AAbb×aaBB。F1的基因型为AaBb,测交后代的基因型为AaBb、aaBb、Aabb、aabb,比例为1:1:1:1,所以表现型及比例为:三角形果实:卵圆形果实=3:1。(2)由(1)解可知,F2中的三角形果实有八种基因型,其中的AABB、AAbb、aaBB、AaBB和AABb,连续自交的后代都不会出现卵圆形(aabb),共占F2总数的7/16,占三角形果实的7/15,而自交后出现性状分离的有AaBb、Aabb和aaBb。

(3)基因突变具有不定向性,所以A、B可以突变成a、b,也可以突变成其他多种形式的等位基因;生物进化的实质是种群基因频率的定向改变,这是通过定向的自然选择积累适应环境的突变来实现的。

(4)采用先测交再自交或连续测交两次的方法进行基因型鉴定。AABB与aabb测交,后代是AaBb,其自交后代都会出现性状分离;AaBB与aabb测交,后代是两种:AaBb和aaBb,前者自交后代出现性状分离,后者没有;aaBB与aabb测交,后代只有aaBb,自交后代不出现性状分离。

【答案】

(1)AABB和aabb自由组合三角形:卵圆形=3:1AAbb和aaBB

(2)7/15AaBb、AaBb和aaBb

(3)不定向性(或多方向性)定向改变

(4)(答案一)

①用3包种子长成的植株分别与卵圆形果实种子长成的植株杂交,得F1种子

②F1种子长成的植株自交,得F2种子

③F2种子长成植株后,按果实形状的表现型统计植株的比例

IF2三角形与卵圆形植株的比例约为15:1

ⅡF2三角形与卵圆形植株的比例约为27:5

IIIF2三角形与卵圆形植株的比例约为3:1

(答案二)

①用3包种子长成的植株分别与卵圆形果实种子长成的植株杂交,得F1种子

②Fl种子长成的植株分别与卵圆形果实种子长成的植株杂交,得F2种子

③F2种子长成植株后,按果实形状的表现型统计植株的比例

IF2三角形与卵圆形植株的比例约为3:1

ⅡF2三角形与卵圆形植株的比例约为5:3

IIIF2三角形与卵圆形植株的比例约为1:1

复习策略

遗传中的实验设计题包括个体基因型的推断、显隐性的判断、设计杂交实验,通过子代的性状判断个体的性别、设计杂交实验判断基因所在的位置等。对于遗传实验设计题的复习,要掌握住常用的方法,比如杂交、自交、测交,注意它们的应用范围。多做题、多总结,做到举一反三,才能够实现这部分的高分突破。

总之,遗传与变异在高考试卷中出现的频率非常高,而且大多作为综合运用能力的考查载体,多以非选择题的形式出现,考查的热点不变,但在考查形式上推陈出新,信息提供形式多样,读题量大,意在考查学生获取、转换信息的能力,基本上属于中等难度以上的题。试题题干背景往往和生产实际相联系,体现了关注社会、关注生活的课程理念。所以在复习这部分内容时要全面细致地回归教材,依次梳理知识点,兼顾前后知识的联系,通过一定的方式建构模块知识结构和体系,并注意总结解题规律,注重解题思路的梳理和解题方法的训练,不断提高自己的解题能力,真正做到记忆准确、理解透彻、运用灵活。

大部分人厌倦了听父母的话,因为他们的父母之前和他们说了很多次,长期下来,人们会对父母的话充耳不闻。

特别是青少年,他们叛逆,和父母说的对着干。

我就是其中一个,当我开始听到父母的喋喋不休,我装作听她的话,事实是我并没有把她说的放在心上。

有一天,我在购物的时候把手机弄丢了,我很担忧,开始想起父母的话,他们一直告诉我要小心,但是我就是听完就丢掉。

我学到了教训,我们应该听长辈的话,他们经历了那么多,告诉我们的都是值得我们学习的宝贵经验。

i am not a brave girl, i am afraid of losing face in front of my friends and parents, so i always let the chance go and refuse to try. once, i have a chance to take a performance in the christmas show, but thinking about if i performed badly, all my friends would laugh at me, so i gave up the chance. but now, i am tired of letting so many chances to go, i want to try, after seeing my friends take all the chances to try, i am not going to be the outsider all the time, i want to live my own life and make some differences. people say failure is not terrible, the unforgettable thing are to lose the courage to try and then making all kinds of excuses. let’s take out our courage and do what we want to do.

我不是一个勇敢的女孩,我害怕在朋友很父母面前丢脸,因此我总是让几乎溜走,拒绝去尝试。

曾经,我有机会在圣诞节目上表演,但是一想到如果我表演不好,所有的朋友都会取笑我,所以我放弃了机会。

但是现在,我厌倦了让那么多的机会溜走,我想要尝试,在看了那么多的朋友抓住所有的机会尝试以后,我不准备再当个局外人,我想要活出自己的生活,有所作为。

花开倾城,花落依然。流年里,你是生命最美的风景,是年华庄不舍的眷恋。愿,流年相伴,用文字,书写一阕不离不弃的牵念,已字相惜,以情相融,给情谊一个莫失莫忘的永远。时光不老,我们不散;时光老去,牵念依然。

晨曦送走了夜晚中最后的一丝黑暗,涌现出一丝光明,我还是走在那条充满水洼的乡间小路上。闻着花香,听着鸟儿在歌唱,心情非常愉快。

到了学校,我跨进大门。走到停车场,我感觉今天和往常不一样了。因为今天有一个人没来。到了教室,我左看右看,哎,今天为什么她没来,我没多想,老师跨进门说:“我们班的一位同学今天没来是因为他要转学了,当我听到时一阵难过。

课下,同学们都纷纷跑出教室,而我坐在座位上看向他的位置,想了想我们之前的美好时光。晚上放学后我跑到他家的门前,看着他们的家,突然门开了,他出来了。他看着我,我也看着他,我们互相对视着。有一种不可分离的感觉。他说道:“原因是我的学习成绩一直下降,没有人检查我的作业,并且没有人照顾我。我的爸爸妈妈想把我接过去看着。”说完,我连忙点点头,此后。我终于明白了,原来是因为他的爸爸和妈妈在那边工作,他也得去,他舍不得离开这个家和爷爷奶奶,他也离不开这个学校。

到了第二天清晨,我还是走进那熟悉的教室,看着那熟悉的座位,我的泪水在眼里打转,我又回忆起往事。回忆起我们的故事,我的眼泪哗啦啦的掉下来像那晶莹断了线的珍珠。我和他的友谊一点也不一般。

【篇6】高考英语作文命题热点

考研英语大作文命题规律 关注热点

历年的考研作是与当下结合非常紧密的题材,考生也都会按照相应的方法进行复习。那么,作为考研英语的最后一道题目,大作文也有自己的命题规律。我们根据多年的辅导经验总结出了以下五大规律,以供的考研同学们进行参考。

1.关注热点。

关注偶像崇拜现象,关注网络问题,的考察环保问题,都是大众或者是青年人关注的热点。在年底时可以从网络上搜集到本年份大事记,从而有侧重的准备相关词汇和句型。提醒20的考生注意:出题者为避免作文题目被猜中,往往可能会将热点延迟进行命题。所以考生在准备大作文的时候可以参考本年和前一年所发生的大事进行预测。

2.与大学英语四、六级考试有关联。

2008年6月的CET6作文题目:《电子书是否可以替代传统书籍?》,20考研英语作文的题目是《网络的近与远》;年12月的CET6作文关注“参加各种艺术培训班”,2009年6月的CET4作文围绕着“博物馆”,考研英语大作文题目是《文化火锅》,可见,考研大作文题目偶尔与四级考试的作文题目相关,常常与六级考试的作文题目相关,近期CET考试的作文题目为考生们提供了练笔、积累素材的好资源。

3.考题倾向于大型宏观话题。

爱心,成长,家庭,20文化,20环保。试卷中给出的.图片、图表只是表达局部或单个情况,入口小,话题大,命题从来不在细枝末节具体环节、或个别事件上做文章。社会积极面是命题主旨的趋向,考生需要以成熟主流的心态来思考问题的积极解决方案、在图画寓意中发现哲理。

4.避开政治和敏感话题

为避免过多的争议,政治话题因其观点难以达成普遍共识,是非曲直难以一时断定,不适合成为考题。敏感性话题同样也不适合成为考研英语的作文题目。

5.命题中的“和谐社会”倾向

围绕主流思想和时代背景,考研作文命题团队已经逐渐形成了以“和谐社会”为核心的命题思路和模式。可以用和谐的三个不同层次对“和谐社会”倾向下的作文话题进行划分:和谐发展之――个体,和谐发展之――个人、他人与社会,和谐发展之――人与自然。密切关注此类话题,掌握与“和谐”相关语词备考,是考生备考的当务之急。

【优秀满分范文】

Dear Jenny,

How is your survey on mobile payment going? I’m glad I can help with it.

It is generally believed that China is the largest mobile payment market. Nowhere else is the cashless trend more obvious than in China. Most of us are used to paying by scanning QR codes whatever we buy—books, clothes, and electronic devices, to name a few, which is a glimpse into the life of most Chinese like me and my family.

With the widespread use of mobile payment, Wechat or Alipay is the most convenient and safest way to pay. We rarely need to carry a wallet or cash at all. Besides, never will we worry about getting fake notes or having to count change. In short, mobile payment has greatly changed people"s life in China.

Personally, I think mobile payment should be encouraged. First, it has won over consumers with its convenience. Another advantage is that there are often discounts if you make mobile payment, as major online payment platforms are competing to have more consumers use their service.

I hope my explanation can be of some help to you. Wish you good luck.

Yours faithfully,

Li Hua

Nowadays, we can see many people are watching their mobile phones in subway, restaurants, elevators, roads and so on. There is no denying that people who like the mobile phone are concerned about its attractive functions. Phubbers can’t stop sending messages, surfing the Internet, listening to music and even taking photos by using the mobile phone. Moreover, some people have less time to relax themselves. They make use of the time when they are on the way to school or other places to play mobile games.

However, phubbing disturbs not only our study but also our life. On the one hand, phubbers waste lots of time playing cell phone games and sending messages, particularly in class. Other people also complain they are disturbed when phones ring in classrooms. On the other hand, it can lead to health problems. For instance, using a mobile phone on the sofa can cause back and neck pain.

As far as I am concerned, it is high time that we threw away the phone and raised our heads up. Do cherish everything around us and appreciate the scenery ahead of us. What’s more, we should do more exercises and take part in real-life activities. In a word, only when we use the phone reasonably, can we realize the happiness of life.

Great changes have taken place since the19th National Congress of the Communist Party of China. The targeted poverty reduction has reached its ideal aims. Many poor families have got effective help from local government and have improved their life greatly. Many old houses are replaced by new tall buildings which are surrounded with green trees and colourful flowers. The rivers that had been polluted seriously before are getting clearer and clearer.

【篇8】高考英语作文命题热点

全国高考的作文命题热点

日前,全国高考考试大纲出炉,在第6页最底下一行,用比正文小一号的字体写着“每一个错别字扣1分,重复的不计”。高考这一条新变化“语文试卷每写一个错别字扣一分”受到各方关注,都市时报综合了湖北省实验中学语文备课组高级教师李玲、武汉武昌区教研室语 文教研员张银华老师等名师,就各科考纲进行解读,谈变化提备考建议。

作文命题关注雪灾等热点

名师点评:湖北省实验中学语文备课组高级教师 李玲

“阅读部分”学生应该从整体上把握文章的特点、语言特色。不要只抓住文章重要的段落,重点句子,要从大局把握整体。尤其是评论类的古诗文应该知道某些鉴赏术语。

写作方面,湖北省历年来的出题都比较新颖,同时与社会生活联系紧密。学生备考时,要关注社会热点话题,比如抗雪灾等内容。这些年,作文题目非常强调时代性和学生个性。现实生活中要学习积累材料,关注生活中的热点。比如感动中国十大人物、荆楚十大人物等题材都可以很好的利用。同时要重视书写的规范性。

“错字扣分”有3种可能

名师点评:武昌区教研室语文教研员 张银华老师

该要求打了条横线放在最下面,有3种可能:一种是自主命题的省市自行选择是否在全卷扣分,一种是没有硬性规定,可以不用扣分,还有一种是只在作文中扣分。过去高考的"考纲对错别字扣分没有明文规定,却有关于错别字的试题。但是,在作文评分细则中有不成文的规定,每错3字扣一分。

现在小学更关注动口动手,开始弱化认字,忽视基础知识的培养。而中学阶段过分依赖电脑,错别字、病句、标点不规范的比较多,这些对使用汉字有很大影响。据以往高考来看,学生在高考作文中因错别字失分较严重。

英语:增加240个词汇

名师点评:武汉一中高教教师、高三备课组组长 沈继英

和去年相比,今年英语考纲没有变化,只是在“语言运用”中,将“写作”改为“写作要求”,使得语句更规范。

不过,湖北英语科的补充说明相对去年而言有变化,增加了240个词汇。这说明了英语高考命题更加重视应用能力的考查,考生需要广泛阅读,提高单词量和阅读量。

数学:注重交叉点考查

名师点评:武汉一中高级教师、高三备课组组长 王以清

与去年相比,今年的全国考纲没有任何变化,保持了稳定。从近年的高考试题来看,可分析出以下命题趋势。

重视基础,突出能力立意,着力内容创新。因此,平时复习时,学生可强化快速、准确地计算训练。解答题的后3题,对学生的能力要求较高。平时复习,应通过专题训练,了解高考命题特点和规律,感悟试题的思想方法和变形技巧。学生要学会从题干找出解题“入口”,以数学思想方法为指导,提高推理、运算的变形能力。

题型、题量和赋分值保持不变。近几年,高考对试卷结构、难度控制进行了细化,一直保持不变。其中,容易题难度系数在0.7以上,中等题在0.4至0.7之间,难题在0.4以下,试卷总体难度适中。

注重交叉点考查。从考纲补充说明的命题指导思想来看,自主命题一直以思维能力为核心,全面考查学生的各种能力,在新旧知识交汇点处考基础,在思想方法的交叉处考能力,在能力层次的交叉处出创新。记住规范答题,避免不必要失分。
