范文
In recent years, the vast majority of Chinese parents tend to make arrangements and decisions for their children. And most children take such excessive attention for granted and depend on their parents for almost everything. According to a survey, of all the parents interviewed, over 80% still accompany their children to schools, even to examinations, and more than 85% do housework for their kids including cooking meals and washing clothes.
However, kids cannot depend on their parents forever because it is just a matter of time before their parents are too old to look after them. Besides, being independent is such a good quality as to help kids succeed later in the world of tough competition. Therefore, parents need to realize the importance of helping their children to be independent.
Parents should encourage their children to make decisions on their own and to take responsibility for themselves. By doing so, parents actually help them develop an ability to think independently and become a responsible individual. In addition, parents should urge their kids to take care of their own business and to work for what they want. For example, if Jack’s bedroom is in a mess, Jack’s parents, instead of cleaning it up for him, should ask Jack to do the job himself as soon as possible. Similarly, when Jack wants a new toy, they should ask him to do some work, say memorize 100 English words, before they agree to his request.

范文
The modern world runs on energy, most of which comes from coal, oil and natural gas. These resources have one thing in common: their reserves/supplies are limited, so they can be used up/exhausted. On the other hand, as economies develop fast, the world’s demand for energy is growing enormously day by day. The two factors combined help us understand why we are threatened with the approach of energy crisis.
What, then, can we do to prevent energy crisis? The answer lies partly in conserving energy sources. Large amounts of energy are being wasted in all sections of the modern society. We need to raise the public awareness of the importance of using energy economically and urge our governments to pass laws to ensure a rational exploration and development of exhaustible resources.
Of course, conservation is not the sole/only solution to the energy problem. Even if the prospect that natural resources like coal and oil will run out is inevitable, many renewable sources of energy are already available, such as wind and solar power. We need to take measures to encourage scientists to continue developing such new sources of energy.
We are convinced that so long as both solutions are applied, energy crisis can be prevented.

范文
Recently, a survey was carried out on students’ attitudes to breakfast. The findings are quite surprising to us / just what we expected.
Only a few students take breakfast seriously while the vast majority of students just eat their breakfast in a hurry. Worse still, some students even go as far as to skip breakfast.
When asked how they accounted for their choices, students gave different answers. But the most common reason is that they tend to oversleep and lack enough time for breakfast. Therefore, they don’t bother with breakfast. Instead, they prefer a big meal at lunch or some snacks between classes.
In my opinion, skipping breakfast is really a bad habit. Not having breakfast will do great harm to our health and cause our body to malfunction. Moreover, attending a class on an empty stomach, we will not be able to concentrate or keep up. So for the sake of our health and study, we should make sure that we eat breakfast on time every day.

Advantages and Disadvantages of the Internet
As every coin has two sides, the Internet, too, has both advantages and disadvantages.
The main benefits of the Internet are as follows. Firstly, thanks to various kinds of search engines, it is no longer a tough job to obtain the information we need, whether it be the latest news or some historical data. In the second place, we can contact friends or business associates by email or other devices such as QQ and MSN, which are cheaper and more convenient than traditional means of communication like phone calls and letters. Last but not least, the Internet provides a platform where we can discuss or debate issues of common interest, and exchange or share things with others.
However, the negative effects of the Internet cannot be ignored. To begin with, surfing the Internet can be addictive to teenagers who, without enough self-control, tend to waste considerable amounts of time and energy playing online games. As a result, they have trouble concentrating in class and lag behind in learning. Secondly, staying too long on the Internet may do harm to our physical health, in particular our eyesight. Prolonged exposure to a computer screen will lead to strained eyes. Finally, since the Internet offers easy access to a rich source of information, we, when looking for answers, will probably not take the trouble to read through reference books. Instead we may be tempted to plagiarize others’ answers from the Internet.
In conclusion, as a technological development, the Internet, despite its flaws, has made information flow around the globe faster and brought people around the world closer. In other words, the advantages of the Internet outweigh its disadvantages.

范文
Today in China as well as in many other countries, an increasing number of people go to work by bike. This trend/practice should be encouraged/advocated for its following advantages.
First of all, bicycling to work helps to lighten the burden on public transportation, which is already too crowded. In rush hours, it often takes a lot of waiting to get on a bus and to transfer from one bus line to another, no wonder a cyclist often arrives at his workplace sooner than his colleagues who are stuck in traffic jams.
In addition, cycling needs no fuel and therefore does not in the least pollute the air. It benefits not only the rider himself but also everyone else of the whole community. Just imagine how much fresher the morning air would be if everyone rode a bike to work.
Last but not least, cycling helps improve people’s health. Nowadays, with the automation of factories and offices, many people’ work has been reduced to button-pressing. What better exercise could such workers have than cycling to and from work?
To sum up, bicycling to work contributes to easing overcrowded traffic, reducing air pollution and improving people’s health.

Threats to Endangered Species
Many species are now in danger of dying out. / Many species are now faced with the threat of becoming extinct. There have been reports about the extinction of tigers, whales and hundreds or even thousands of other animals.
Among the threats to engendered species are human activities, which can spoil or ruin wildlife habitat. For example, forests and grasslands are cleared to develop residential or industrial areas for people to live or work in. Besides, an increasing amount of chemical waste is dumped into rivers for the convenience of economic development. All these human activities can make wildlife habitat shrink considerably, thus pushing species to the brink of extinction / thus threatening species with extinction.
To prevent endangered species from dying out/becoming extinct, we should draw up rules and regulations to ban the human destruction of wildlife habitat. In the meantime, great efforts should be made to encourage people to strike a balance between environmental protection and economic development/ adopt an environment-friendly approach to economic development.
Threats to Endangered Species
Many species are now in danger of dying out. / Many species are now faced with the threat of becoming extinct. There have been reports about the extinction of tigers, whales and hundreds or even thousands of other animals.
Among the threats to engendered species are human desires for food and clothes, which can lead to overhunting. For example, an increasing number of whales are killed to make traditional dishes in Japan. Besides, some wild animals like deer and tigers are skinned to make fur coats for those who live in luxury. Such acts of killing can reduce wildlife population considerably, thus pushing species to the brink of extinction / thus threatening species with extinction.
To prevent endangered species from dying out/becoming extinct, we should draw up rules and regulations to limit the commercial hunting of wildlife. In the meantime, great efforts should be made to encourage people to have a diet free of endangered species and wear fur coats made of artificial materials

As living standards keep rising, more and more parents see their children’s education as a top priority. They are willing and able to send their kids abroad for studies. Meanwhile, many foreign universities are opening the door to Chinese students, who have displayed enough talent and hard work to attract their attention. As a result, an increasing number of Chinese students choose to go abroad for further education. Frankly speaking, studying overseas has both advantages and disadvantages.
Those who argue against the trend say that living far away from home, Chinese students tend to suffer from loneliness and homesickness, since they are used to being taken care of by their parents. In addition, most students in China lack enough experience of living alone, which makes it difficult for them to adjust to everyday life in a foreign country.
However, those who support the phenomenon argue that studying abroad, Chinese students find it easy to improve their foreign language, since they have to use it every day. Besides, compared with domestic colleges, foreign universities have academic advantages, including advanced facilities and excellent professors. Chinese students, therefore, can receive better academic training in science and technology and keep up with the latest developments in their fields. Last but not least, when they graduate from a foreign university, they will have more career choices both in china and abroad.
In my opinion, attending foreign universities has more advantages than disadvantages. Being exposed to a foreign culture broadens a student’s horizons. Living alone overseas helps a student become independent. Foreign universities provide students with easy access to world-class scholars and academic resources. A degree from a foreign university opens up a wider range of career choices to graduates. In short, I will choose to pursue a better education overseas if my parents can afford it.

What Electives to Choose
Nowadays, many universities provide a variety of electives for students to choose from. The standards by which to choose electives differ from individual to individual.
Some students, who have made their career choices, prefer the electives relevant to their future jobs. Some students choose the electives that will help their major studies. Others take the electives whose contents are similar to their hobbies. There are also a few students who care little about the nature of electives and choose those where it will be easy for them to get enough credits.
As far as I am concerned, most electives are supposed to equip me for future jobs. Since I want to become a car mechanic, I prefer electives that will give me basic instructions in car repair and maintenance.

Last Sunday, it was a sunny day, and I had an opportunity to visit a well-known university campus.
Upon entering the campus, I was greeted by the pleasant smell of flowers and the friendly smiles of teachers. Walking on campus, I saw students playing basketball, reading books, or riding bikes. When I stepped into a building, I was amazed to find all classrooms filled with students either attending lectures or doing self-study. I went into one lecture-room and asked a student there what the lecture was about. He was happy to hand me his notebook. A glance at his notebook showed how attentive he had been. Upon leaving, I thought to myself that I would apply to this university for postgraduate studies.
Compared with my college, the university has a variety of lectures and courses that will help enrich my knowledge and broaden my horizons. This visit not only let me briefly experience a different university atmosphere, but also inspired me to study harder to pursue a better education.

Then grasp your chance with your perfect performance o n the dating night, by learning the following principle in heart. Dress properly. While everyone wants to give an impressive debut on the first date, you should avoid wearing something too bizarre to be accepted. If you are st ill in school, a sportswear can fulfill your purpose. For businessman or grownups, c asual clothes are recommended. Never put up your working uniforms,no matter ho w well you like that Armani suit. It is no work. A few accessories such as a pair o f sunglasses or silver loops on the wrist can add up to the romance sphere. Take a bath before dating. And if you like, spray a little perfume, but unless y ou＇re sure that he or she likes the smell,don＇t use ones that are too strong. Watch your manner. You＇re no prince of the Scotland nor Cinderella in the le gend. Proper manners will ensure a lasting relationship while bad ones scare away your sweetheart. And do make sure you do not boast about your fortune, for, not everyone are green addicts. And your way of smiling, or your greatestoath, should neither be "coy" nor "by St. Loy!" after the nun in Chaucer. Be a little sensitive than merely innocent. Do make sure you do not intrude hi s or her privacy on the first date. For there maybe something deeply concealed wit hin the inner core of every heart, of which the owner doesn＇t share often with an yone but his intimacy. Finally, wish you good luck.

大学英语作文四级万能模板 开头万能公式 1．开头万能公式一：名人名言 有人问了，“我没有记住名言，怎么办？尤其是英语名言？”，很好办：编！ 原理：我们看到的东西很多都是创造出来的，包括我们欣赏的文章也是，所以尽管编，但是一定要听起来很有道理呦！而且没准将来我们就是名人呢！对吧？ 经典句型： A proverb says, “ You are only young once.” （适用于已记住的名言） It goes without saying that we cannot be young forever. （适用于自编名言） 更多经典句型： As everyone knows, No one can deny that… 开头万能公式一：数字统计 原理：要想更有说服力，就应该用实际的数字来说明。 原则上在议论文当中十不应该出现虚假数字的，可是在考试的时候哪管那三七二十一，但编无妨，只要我有东西写就万事大吉了。所以不妨试用下面的句型： According to a recent survey, about 78.9% of the college students wanted to further their study after their graduation. 看起来这个数字文邹邹的，其实都是编造出来的，下面随便几个题目我们都可以这样编造： Honesty：根据最近的一项统计调查显示，大学生向老师请假的理由当中78%都是假的。 Travel by Bike：根据最近的一项统计调查显示，85%的人在近距离旅行的时候首选的交通工具是自行车。 Youth：根据最近的一项统计调查显示，在某个大学，学生的课余时间的70%都是在休闲娱乐。 Five-day Work Week Better than Six-day Work?：根据最近的一项统计调查显示，98%的人同意每周五天工作日。 更多句型： A recent statistics shows that … 结尾万能公式 1．结尾万能公式一：如此结论 说完了，毕竟要归纳一番，相信各位都有这样的经历，领导长篇大论，到最后终于冒出个“总而言之”之类的话，我们马上停止开小差，等待领导说结束语。也就是说，开头很好，也必然要有一个精彩的结尾，让读者眼前一亮，这样，你就可以拿高分了！比如下面的例子： Obviously（此为过渡短语）, we can draw the conclusion that good manners arise from politeness and respect for others. 如果读者很难“显而见之”，但说无妨，就当读者的眼光太浅罢了！ 更多过渡短语： to sum up, in conclusion, in brief, on account of this, thus 更多句型： Thu s, it can be concluded that…, Therefore, we can find that… 如此建议 如果说“如此结论”是结尾最没用的废话，那么“如此建议”应该是最有价值的废
