中考考前预测作文(精选3篇)

中考考前预测作文(精选3篇)

中考考前预测作文(精选3篇) 中考考前预测作文(精选3篇)第一篇:中考考前预测作文学会欣赏作文生命的途中,有鲜花,也有泪水。

有美好的风景,也有作呕的地方。

人的一生不可能会善始善终,也不可能会饱受折磨。

学会从另一个角度去欣赏他们,便会成为一道亮丽的风景线。

学会欣赏,欣赏亮丽的风景。

人的成功是美好的,让人心旷神怡。

当你落寞时,向后看看你的成功,会燃起男子汉的心,熊迈豪气的威风重振。

当你欣赏祖国的壮美山河时,会不会想到你的成功经历呢?学会欣赏,欣赏灰暗的寂寞。

一个人的寂寞很可怕,但可以另外去理解它。

人过于热闹了,倒不如清幽一些。

陶冶情操,锻炼心智,变得清高,不在逊于古代各朝名门诗人,做出一种寂寞是金的模样。

学会欣赏,欣赏失败的痛苦。

我们重重的跌倒在地,四周黑暗,讥笑一片,不必恐惧,那是妖魔考验你的坚贞。

那是你的胆小一面,你只需要去战胜失败,从中吸取精华,不被他打败,要能学会欣赏光辉上得一个污点。

学会欣赏,欣赏他人的嘲讽。

别人对你的讥嘲,不是嫉妒,便是看低。

你可以看为他们用强烈的危机感去打压你,让你喘不过气,确实让你拥有了超强的忍耐力,学会挣扎和反抗。

能够如此想,是对自己的一种精神帮助,也是对别人的一种理解。

学会欣赏,欣赏沿途的一切。

只有学会欣赏一切,你的生活不会那么空虚。

欣赏会让你广交群友,和别人一同欣赏各种努力和失败,会让我们有更深的生活体验与感悟。

欣赏人生,让欢笑代替之前的不谙世事和惆怅吧。

学会看人生,从各个方面去观察理解他,你总有一天会惊奇的发现,之前所有的不愉快是你不懂得去看看他。

我想说,天地间所有事物皆有善恶,但我们可以看得却是所有善恶的所有事。

一旦你种下了种子,果实就决定了他的善恶,但结果长成熟了,你可以学着因果之间奇妙的连证关系,让人久久思索。

学会欣赏,你会活出你独有的精彩的。

第二篇:中考考前预测作文女子雄心“英雄难过美人关。

”漫长的历史没有冷落女子。

周幽王烽火戏诸侯,人们把褒拟骂得如何不是,“一骑红尘妃子笑,无人知是荔枝来”,把杨玉环说得如何不是。

四级考前预测作文30篇

四级考前预测作文30篇

四级考前预测作文(30篇)预测作文1. More People Choosing Overseas Destinations for Their HolidaysDirections: For this part, you are allowed 30 minutes to write a short essay entitled More People Choosing Overseas Destinations for Their Holidays based on the statistics provided in the chart below. Please give a brief description of the chart first and then make comments on it. You should write at least 120 words but no more than 180 words.【范文】More People Choosing Overseas Destinations for Their Holidays From the chart given above, we can observe that the number of people traveling abroad experienced some changes during the past several years. From 1993 to 2003, the number of Chinese people choosing overseas destinations for their holidays increased rapidly from less than 5 million to 20 million, and then to 70 million in 2011.What exactly contribute to this phenomenon? Reasons can be listed as follows: for one thing, the authorities have issued some preferential policies to promote the development of the overseas tourism industry, which encourages a sudden emergence of travel agencies that can provide customers with convenient overseas tourism services. For another, with the improvement of financial status and purchasing power, a considerable number of Chinese people can afford the once-deemed-expensive traveling expenses.By observing the past trends, we may forecast that the growth tendency will continue. However, it is also a highly variable industry which is vulnerable to seasons and climates, international political situation, fluctuations in exchange.预测作文2. On Cosmetic Surgeries1. 近年来,整容现象屡见不鲜2. 出现这一现象的原因3. 我对这一现象的看法和建议【范文】On Cosmetic SurgeriesIn recent years, there have appeared more and more artificial beauties around us. Not only those actresses but also many ordinary women are crazy about cosmetic surgeries. They fail to resist the temptation of becoming more beautiful by changing some parts of their bodies within a few hours’ surgery.What are responsible for the prevalence of cosmetic surgeries? Firstly, thanks to the development of shaping techniques, the chances of successful surgeries have increased greatly, which makes more people begin to believe and accept cosmetic surgeries. Secondly, with the improvement of living standard, people have more money to satisfy their nature of pursuing beauty.From my point of view, cosmetic surgeries have their necessity of existence in modern society. They do help some people build confidence by giving them a beautiful face or figure. However, cosmetic surgeries cannot bring permanent beauty and might be dangerous. Besides, I think one’s inner beauty is more important. Therefore, I suggest that people should think twice before deciding to accept cosmetic surgeries.预测作文3. Goal Setting Is ImportantDirections: For this part, you are allowed 30 minutes to write a short essay entitled Goal Setting Is Important by commenting on John Ruskin’s famous remark, “Living without an aim is like sailing without a compass.” You should write at least 120 words but no more than 180 words.【范文】Goal Setting Is Important“Living without an aim is like sailing without a compass.” This philosophical wisdom by John Ruskin, one of the greatest British writers, tells us that goal setting is extremely important in life. Why is goal setting so important? The main importance of goal setting is that it provides us with direction and purpose. When we have goals, we know what we want to achieve so that we can focus our mindson a single worthwhile target and avoid getting distracted easily. Personal goal setting also provides us with motivation to achieve what we want to achieve.Goal setting is of especial significance for today’s students. A study reveals that when students set goals, they learn the importance of taking responsibility, of minimizing excuses and of helping others. Goal setting is a lifelong skill that first helps students succeed in school and then later in life.预测作文4. Shopping through Media1. 目前许多人通过媒体购物2. 媒体购物有利有弊3. 我的看法【范文】Shopping through MediaWith the development of science and technology, it is much more common for people to buy goods through different kinds of media than before. People can buy things such as computers and necklaces through TV, radio, the Internet, etc.Shopping through media is welcomed by most people due to various reasons. From the perspective of consumers, it can save time for people who don’t have much spare time. For retailers, it can cut costs for those without much circulating funds. However, there are still some defects in shopping through media. First, compared with face-to-face deal, it seems less reliable and trustworthy. Second, people will lose the fun of bargaining.In my view, although shopping via media brings great convenience to us, we still should be brings great convenience to us, we still should be careful when we “go shopping” through media. We should check the information released by the media. Only in this way can we fully enjoy the convenience brought by media shopping without the concern of being cheated.预测作文5. Parents’ Being Slaves to Children1. 现在有些父母成为“孩奴”2. 出现这种现象的原因3. 这种现象可能产生的影响【范文】Parents’ Being Slaves to ChildrenParents’ being slaves to their children or “child’s slave” is nowadays a hot topic in China. It refers to young parents who have to spend a large part of their income on children. These parents feel great strain under the burden of raising a child and struggle hard to make as much money as possible.The cost of raising a child in China is becoming greater and greater. But economic pressu re is not the only reason that makes young parents “child’s slave”. Parents’ competing with each other in trying to provide the best possible living conditions for their children should also be blamed.If this problem continues, it would affect parents and the development of our country. These parents would suffer from huge economic pressure, which may pose a threat to their marriages or physical and mental health. On the other hand, to avoid being slaves, some couples are unwilling to have children.预测作文6. Due Attention Should Be Given to Speaking1. 如今不少学生在英语学习中不重视口语2. 出现这种现象的原因是……3. 为改变这种状况,我认为……【范文】Due Attention Should Be Given to SpeakingNowadays fewer and fewer students pay attention to their spoken English, which results in a dramatic increase in the number of students who can spell English words but are incapable of speaking them fluently or correctly. This phenomenon has aroused many people’s attention.Why does such a phenomenon emerge? As far as I’m concerned, there are possibly two reasons contributing to this phenomenon. On the one hand, exam-oriented education makes many schools lay emphasis on passing the English exams, which leads to the lack of speaking environment for students to practice their spoken English. On the other hand, students themselves don’t realize the importance of the ability to speak English which has a great influence on their future study and career development.To change this situation, I think, we can take the following measures. First, the importance of o ral English should be emphasized to raise students’ awareness of the necessity of speaking English. Second, exams should be modified to make students pay attention to their spoken English. Third, schools can organize various activities to arouse students’ interest in speaking English.预测作文7. Creating a Harmonious Campus1. 建设和谐校园很重要2. 和谐校园不仅指和谐的环境3. 为建设和谐校园我们应该……【范文】Cre ating a Harmonious CampusA harmonious campus is of vital importance. It is just like a solid, colorful and appealing textbook. It nurtures the students’ mentality, beautifies their minds, sparks their aspirations, enlightens their wisdom and accelerates their overall development.When it comes to a harmonious campus, we do not merely mean a beautiful environment on campus. We also mean a healthy interpersonal relationship, where teachers and students get along well, while students respect and care for each other. We mean a sustainable campus that brings teachers and students to fully play their enthusiasm and positivism as well, while at the same time reinforce campus regulations and campus order.The creation of a harmonious campus needs joint efforts of institutes and students. Colleges and universities should introduce advanced campus culture which encourages a variety of creative extra-curricular activities and puts first staff, faculty and students. As students, we should behave ourselves, learn to be tolerant and respect each other.预测作文8. Free Admission to Parks1. 越来越多的公园免费开放,目的是什么2. 也会带来一些问题3. 你的看法【范文】Free Admission to ParksTo encourage people to go outside and relax, a mounting number of parks offer free admission now. People benefit from it, especially during these tough economic times. With free entry, more people will have the opportunity for affordable vacations for families, taking pleasure in the natural landscape.Fresh air and landscapes in parks are good for people. However, too many people flocking into parks might not be so good for the parks.For example, some visitors leave their garbage behind, which may cause environmental pollution. And people’s barbeques and stamping will also bring damage to the grassland and other greeneries in parks.As a university student, I’m in favor of free admission to parks. Free entry to parks not only saves people’s expendi ture, but also makes things fairer — people like the poor and students can go to parks frequently as well. On the other hand, visitors should be informed to preserve the environment while enjoying the beauty of the nature.预测作文9. Green Consumption1. 绿色消费的概念在中国日渐流行2. 中国推行绿色消费还存在许多困难3. 如何解决这个问题【范文】Green ConsumptionThe conception of green consumption has gradually become popular in China. More and more green foods are making their appearance on the market and more and more people are becoming conscious of environmental protection.However, there still exist quite a few difficulties in the further promotion of greenconsumption. On the one hand, many people are still not quite clear of the advantages of green foods. On the other hand, due to high profits, many fake green foods are found in the market. Moreover, many consumers don’t want to pay extra money for green foods.There may be several ways to solve these problems. Firstly, the government should supervise the good quality strictly to protect con sumers’ interests. Secondly, the conception of green consumption should be further promoted and emphasized. Thirdly, the government should work together with manufacturers to make the price more reasonable.预测作文10. The Internet1. 有人认为网络可以让学习、工作更有效率2. 有人却认为网络让青少年沉迷,影响学习3. 我的看法【范文】The InternetIn the era of information and technology, the Internet plays an important role in our society. However, people’s opinions are still divided on this point. Those who are in favor of the Internet claim that it has a lot of advantages. Firstly, information searching is no longer a tough job with the help of all kinds of search engines. Secondly, we can contact friends or business partners via e-mails or software such as Internet Meeting and Yahoo Messenger.Those who are opposed to the Internet hold that its disadvantages are numerous. In the first place, using the Internet costs considerable time, money and energy, especially for those with poor self-control. In the second place, increasing young people are indulged in online games and unhealthy information, which are extremely harmful to their development.In my opinion, its pros outweigh the cons. The past twenty years have witnessed the fast development of the Internet along with the national economy. A brighter future is awaiting us if we make good use of the Internet.预测作文11. Youngsters’ Worship1. 大学生现在过分崇拜大明星2. 分析产生这一现象的原因3. 我的看法【范文】Youngsters’ WorshipNowadays, star-worshiping is popular among teenagers, especially many university students.Why? When it comes to the symptoms of worshiping a star, the main factor I’d like to mention is imitation. With a blind love for their idols, teenagers firmly believe that their choices are the best. As a result, the stars’ clothes, hairstyles and hobbies, as well as their behaviors in public, are closely observed or followed, though, to some extent, they may be considered improper or even ridiculous.In my opinion, having idols is not a bad thing. However, we should make it clear who are the real “heroes”. As far as I am concerned, the real heroes are those who are making the most contributions to our society, such as teachers, doctors and scientists. As students, we should learn from them. Only in this way can we become useful persons in the future.预测作文12. On Moral Building on Campus1. 校园道德建设十分重要2. 因此,学校可以……3. 我们自己应当……【范文】On Moral Building on CampusRecently, if you search the internet or other media, you would see reports on demoralization now and then. Universities are no exception. These demoralization shows in the following aspects: theft, lack of credibility, cheating in examinations, plagiarism in papers, improper interaction with the opposite sex etc. In sum, moral building on campus is of critical importance in students’ all-round development.On one hand, this requires the universities to attach great importance to natural environment planning and building. A good campus environment plays an active role in cultivating students’ ideology and moral education. On the other hand, the staff in the university should find the best in both Chinese and Western culture to educate the students. Students can learn important lessons from Western cultures, adding to our profound morality.We, as students in the university, should be aware of the importance of moral building. We should do something to support the moral building work, starting from little things around us. Students Union should organize some activities for students to take part in, highlighting the importance of moral building.预测作文13. On Dishonesty in Tourism1. 近年来旅游行业中不诚信现象比较普遍2. 出现这一现象的原因3. 我对这一现象的看法和建议【范文】On Dishonesty in TourismSince 1980s, the economy of China has developed greatly.

李白被贬回乡,却豪放不减,安心享受难得的自由。

于是,有了“且放白鹿青崖间,须行即骑访名山”;“安能摧眉折腰事权贵,使我不得开心颜”的潇洒与大气。

苏轼流放海南,却悠然依旧,安心享受难得的悠闲,于是,有了“日啖荔枝三百颗,不辞长作岭南人”的自在。

李白、苏轼仕途失意,但内心却并不为之所动,而是依然心安自在,快乐满怀,于是,成就了他们驰骋诗坛,流芳千古的伟业。

心安者,成万事。

身处逆境时,需要心安。

史铁生,不到二十,下身就残废,但他却并未被吓倒,而是安心于写作,终于成为现代文坛一颗耀眼的明星;海伦·凯勒,双目失明,但她却并未被压弯,而是安心练习说话,终于成为生活的强者、世人学习的楷模;史蒂芬?霍金,全身仅有两根手指能动,但他却并未被击垮,而是安心努力用两根手指写书和工作,终于,一部《时间简史》惊叹世人。

他们,都是生活中的不幸者,然而,他们却用内心的安然和自身的努力,使自己成了生活中的万幸者。

心安者,成万事。

面临成功时,需要心安。

试想,如果没有居里夫人在发现钋后仍安心钻研,怎会有化学元素“镭”的发现?如果没有我国领导人在国家高速发展之时,仍不满足于现状,安心办事,怎会有中国今日傲立于世的辉煌?不沉湎于已有的成绩,安心创造新的业绩,一次次的成功必将不断垂青于他。

心安者,成万事。

前方乌云密布,与其无方向乱窜,不如安心静待并不断积蓄能量,待准备好,调整好,以一颗安然之心,借风之势、山之力,还怕撑不出个晴空万里?面对坎坷,安心处之;遭遇失败,安心处之;面对成功,安心处之。

朋友,携一颗安然的心,快乐出发吧!梦想,就在不远处。

心安者,成万事。
