In current society, people have known the importance of keeping healthy and good life habit. In the past, people ate three meals at home, and they ate more vegetables and less meat and fish. They were very strong and seldom went to see doctors.

Now life is better, people eat more meat, fish, eggs and other food with more fat. They often go out for good meals with their families and friends. But they get easy to be ill, Why?

I think more meat and fish, less exercise are bad for health. Good rest, less meat and fish, more vegetables and enough exercise are good for health. So I exercise every day. My eating habits are pretty good. I eat a lot of vegetables. I eat fruit and drink milk every day. I drink a cup of water 15 minutes before each meal and eat much vegetables and fruit. Of course, I love junk food, too, and I eat it once a week. And I sleep nine hours every day.

The better we get into good eating habits, the happier our life becomes

这时,小店老板走过来对我说:“喜欢吗?这个悠悠球原价要二十六元,最低二十三元卖给你。”我摸摸口袋,发现只有二十元钱,老板见我十分渴望得到这个悠悠球,就对我说:“那好吧,你先付二十元把它拿走,下次记得还我三元哟!”我喜出望外地答应道:“好的!”我交了钱,一边笑,一边玩,一边高高兴兴地回家了。

然而后来我就将此事忘在了脑后,直到过了几天想起时,我便想,这么长时间了,可能老板自己也忘记了吧。带着这种侥幸的心理,从此每次路过宝小门口,我都避开走,更不敢去跟老板还三元钱。然而我的举动引起了妈妈的注意,妈妈好象看透了我的心思,问我:“你怎么了呀?以前你不是都要没事去店里面看看有没有喜欢的小玩意吗?现在怎么看都不看了?”我立即低下头对妈妈说:“啊、噢,我上次买了一个悠悠球,差了老板三元钱没有不还。。。”我半天才说出了原因,妈妈赶紧给我钱让我现在就去还。

还钱后,我觉得心里舒服极了,我感觉做人一定要做一个诚实守信的人,相倍别人,也相信自己!

篇5:关于初三英语写作技巧汇总

全文共 1728 字

+ 加入清单

一、认真审题,切中题意

《中考考试说明》指出,书面表达要切中题意。看到考题后,先不要急于动笔,要仔细看清题目要求的内容,在自己的头脑中构思出一个框架或画面,确定短文的中心思想,不要匆匆下笔,看懂题意,审清格式、体裁、人物关系、故事情节、主体时态、活动时间、地点等。

二、围绕中心,拟定提纲

书面表达评分原则有四条:(1)内容要点;

(2)运用词汇和结构的数量;

(3)运用语法结构和词汇的准确性;(4)上下文的连贯性。

由此可见,要点是给分的一个重要因素。为了防止写作过程中遗漏要点,同学们要充分发挥自己的观察力,把情景中给出的各个要点逐条列出。注意短文字数不要低于或超过规定的字数太多。

三、语言通顺,表达准确

(1)避免使用汉语式英语,尽量使用

自己熟悉的句型。几种句型可交替使用,以避免重复和呆板。

(2)多用简单句型,记事、写人一般都不需要复杂的句型。可适当地使用陈述句、一般疑问句、祈使句和感叹句。不用或少用非谓语或情态动词等较复杂的句型。

(3)注意语法、句法知识的灵活运用。(4)描写人物时,要生动具体,例如:①外表特征:tall,short,fat,thin,strong,weak,ordinary-looking等;②内心境界:

glad,happy,sad,excited,anxious,interested等;③感情描写:love,like,hate,feel,laugh,cry,smile,shout等;④动作描写:come,go,get,have,take,bring,fetch等。

(5)上下文要连贯。上下文的连贯性也是评分的一条原则,同学们应注意下面过渡的用法:①表示并列关系的过渡词:and,aswellas,or等;②表示转折关系的过渡词:but,yet,however等;③表示时间关系的过渡词:first,andthen,

finally,after,before,atlast,atthattime,later,inthepast,immediately,inthe

meanwhile等;④表示空间关系的过渡词:near(to),far(from),inthefrontof,beside等;⑤表示比较关系的过渡词:inthesameway,justlike,justas等;⑥表示对照关系的过渡词:but,still,yet,however,ontheotherhand等;⑦表示递进关系的过渡词:also,and,then,too,inaddition,moreover,again等;⑧表示因果关系的过渡词:because,since,then,thus,otherwise,so,therefore,asaresult等;⑨表示解释说明的过渡词:forexample,infact,inthiscase,for,actually等。

四、不会表达,另辟蹊径

中考作文给分是以要点和语言准确度而定,不以文采打分。造句越简单准确越好,造复合句容易出错,容易被扣分,阅卷场上有句话:“错误面前人人平等,文采好不加分。”如遇到个别要点表达不出来或难以表达,可采用变通的办法,化难为易,化繁为简。总之,所造句子要正确、得体、符合英语表达习惯。

五、锦上添花,量力而行

如果你还有时间和精力,想把书面表达写得更好,那么,请注意以下几点:(1)句型多样化,不要i(we)……到底,使人觉得乏味;(2)适当使用一些并列句或主从复合句;(3)进一步描绘人或事物时,适当使用定语从句;(4)适当使用分词或分词短语,烘托谓语动词;(5)偶尔使用一下倒装句,增加新鲜感;(6)适当调换一下状语在句子中的位置,使句子不雷同;(7)上下句子紧接时,其中完全相同的成分可以省略,以节省篇幅。

六、书写工整,卷面整洁

字迹要清晰,让阅卷人看得清楚,不可字迹潦草,难以辨认,要保持卷面的整洁。

七、检查错误

检查错误应从以下几个方面入手:(1)格式是否有错;(2)拼写有无错误;(3)语言是否用错;(4)时态、语态错误;(5)标点错误;(6)人称是否用错。

总之,只要平时同学们多练习写作并有意运用上述方法和技巧,合理分配时间,在中考时一定能写出高质量的作文,得到令人满意的考分。

A dream is to a man what wings are to a bird. With a dream in the deep hearts core, a man is spontaneously driven to hitch his wagon to a star.

A dream is an inexhaustible source of energy that keeps our enthusiasm burning, and kindles our desire to enhance our spiritual cultivation, refine our character, and upgrade our quality of life. A life without a dream is like a bird with broken wings, confined to a cage and oblivious of what lies beyond the range of its vision. On the contrary, a man with a dream is like a warrior armed with ambition, foresight and gallantry, daring to step into an unknown domain to make a journey of adventure. It is dream that adds fullness, variety, and spice to our life and makes it worth living.

I have a dream. It is a dream that is deeply rooted in human nature. I dream that one day people of all origins can live in harmony and peace without being discriminated against or persecuted. The bounty of the earth can be shared by every single human being. Mutual respect will guarantee the existence and continuation of the diversity of customs and cultures. Love, sympathy, and cooperation will alleviate the sufferings and disasters inflicted upon our fellow men. Respect for basic human rights will put an end to social injustices and evils. When my dream comes true, all men will be truly equal, happy, and free.

The large number of our population has become one of the most serious problems of our society. according to a recent survey of the national bureau of statistics, there are more than 1.3 billion people in our country, which account for about 1/5 of all the people in the world. the same survey also predicts that our population will grow quickly in the years to come.

overpopulation has brought about a series of negative effects to our economic development and social security. in the first place, too many people impose a heavy burden on our environment. as a result, we suffer from a shortage of fresh water and natural resources. in the second place, as the supply of labor greatly exceeds the demand of the society, many people become employed. this is a source of social unrest. last but not least, we have to manufacture all kinds of products to meet the needs of the people, which causes environment pollution to our lakes and land.

serious though the problem seems, we have to take some measures to tackle it. on the one hand, the government should carry out more strictly the policy of family planning, thus reducing the total number of population. on the other hand, all the people should realize the harms of overpopulation. with the concerted efforts of all the parties concerned, we’re sure to solve the problem in the future.

全文共 683 字

医疗卫生事业的发展使得人口出生率和成活率迅速提高,死亡率大幅度下降,引起全球人口急剧增长。

世界人口递增的时间越来越短。工业革命时期1800年到1839年,世界人口由10亿增加到20亿,到1960年为30亿,1975年为40亿,1987年7月为50亿。发展中国家占世界人口比重由50年代的66.8%上升到80年代的74.9%。至2000年全球人口增加到61亿,其中85%的增加大多集中在亚洲、非洲和拉丁美洲。

而在未来的30年中,人口增加率将会减缓,到2030年时,世界人口,的总数将为80亿。人口增长率将达到历史性的低点。

从文化教育程度看目前,全球有9.6亿文盲,其中1.3亿儿童。发达许多成绩优秀的高中龄毕业生不愿选择理工等相对艰苦的专业,使得在培养艰苦岗位上所需合格人才陷于困境。发展中国家无力培养更多的人才,而人才从发展中国家向发达国家的流失更加剧了发展中国家的人才危机。以印度为例,到1990年为止,在外谋生的科学家和熟练技术人员达41万,到2000年达54万。

从健康的角度看人口素质,许多疑难病、奇特病的增加表明人口素质的下降。如艾滋病、变异链球菌、奥罗凯病毒、登革热病毒、非典病毒等。正以惊人的速度吞噬人类的生命。

发达国家的人口问题

人口总规模萎缩,人口老龄化。1991年,瑞典老人比重18%,英国16%,日本12%。造成的问题:①社会经济负担加重②劳动力老龄化③生产率低④社会问题多。

发展中国家的人口问题

农业人口多,出生率高,“越穷越生,越生越穷”恶性循环。引发的社会问题是,①贫穷与饥饿②失业③奇型城市化,其后果是失业加剧,人口分布奇型,出现大量工棚区。
