句子不完整这个错误是由于很多同学缺乏common sense， 不知道啥叫一个句子的完整，为啥自己写的就不完整。什么样的句子是完整的?一个主语+一个谓语已经可以构成最简单的完整句子。
例如：The society develops rapidly.The society是主语，develops是谓语，此时这个句子 就是完整的。
常见的错误写法：The society developing rapidly.此时这个句子是缺谓语的。
我们需要改写成:The society develops rapidly.或The society is developing rapidly.
一个句子有且只能有一个主谓结构。“我干，他不干”这句话正确的表达方法是：I do, but he does not.或: I do. He does not.然而常见的错误形式是：I do, he does not.此时这句话出现了两个主语：I, he.那么这句话肯定就是错误，我们需要用连接词but隔开，或直接句号后另起一句话。
我们举一个难一点的例子：Some people agree with the first statement, I disagree with it.这种错误的表达常见于同学们的写作第一段。这句话出现了两个主语：Some people; I.出现了两个谓语：agree; disagree.按照我们刚才已经讲过的，一句话不能出现两个主语判断，这句话是有问题的。
Some people agree with the first statement. However, I disagree with it.
或：Some people agree with the first statement, but I disagree with it.
I do; you do; she does; he does; it does.
a. Intelligence leads to success.
Intelligence lead to success.
b. The professor provides great opportunities for students to expand their horizons.
The professor provide great opportunities for students….
我们常用逗号，或连接词如：and，not only…but also…来连接两边平行的一些单词或句子。此时逗号及连接词左右两边连接的内容，需要形式平行，如名词和名词平行，形容词与形容词平行，动词与动词平行。
a. Expensive handmade items are creative and artistic.
b. Working out and taking a rest are the best ways to maintain health.
此处working out和taking a rest是动名词做主语，形式一致，是正确的平行结构。
working out and take a rest… 此处结构就出现了错误。
c. The media gives us information and tells us the truth.
the media gives us information and telling us the truth.
Some people think it is the best approach for students to learn if school start the day at a early time in the morning. But someone think the school should start the day at late time. Which one do you prefer? Use specific reasons and detailed examples to support your answer.
Many schools are planning to postpone the first class in the morning for less lateness and better educating quality. However, the schedule of late classes will cultivate students’ indolence, and pose many other negative effects. As a result, starting class late would not effectively reduce the rate of lateness and cannot secure the educating efficacy.
Firstly, early classes in the morning will force the students to keep a disciplined life style. In order to attend the first class, students have to get up early in the morning. This habit brings many benefits. For example, young people will live a much healthier life. Keeping the schedule in mind, they would no longer dally at night before sleep, and save their time in the morning. Then, they can have a good rest in the evening and keep themselves energetic at daytime. Besides, they could also shape many of their excellent characteristics, like self-discipline or persistence. Leaving the cozy bed requires a powerful willpower when we start a new day, and doing this every day asks for a strong self-control. Both of these virtues are keys to success. And one of the well-known, Kobe Bryant, is a beneficiary of starting his day early in the morning. He once gave his secret to become the MVP in the basketball playground. It was his getting up early in the 4 AM that contributes him. In conclusion, both physical and psychological benefits can be gained by the disciplined life style led by the early classes.
In addition, early start in the morning also leaves more extracurricular time for students. Earlier starting class generally results in earlier off-class. More spare time after class enables students to conduct other activities, such as further exploring in study, deepening their interests or doing some other activities. Those activities would help students to improve themselves. In spare time, students can do some practical experiments to apply knowledge into practice, which allow them to have in-depth understanding in knowledge learnt in class. Students would be also capable of learning instrument, painting or doing sports with abundant of time after class. Those extracurricular activities help students to achieve complete development. Obviously, earlier start in the morning means a longer day, providing more spare time for students to enrich their life and promote themselves in learning.
Late classes, to a degree, may lower the absence rate at the beginning. This is because that students do not need to be hurry in the morning, especially for those who cannot get up early. In the long run, however, the original purpose cannot be realized effectively. The allowance of starting class later would indulge the bad habits of procrastination. Some students will tend to put off all tasks late at night, if they do not need to get up early. Staying up later would in turn make students get up later. This is a vicious circle. As a result, students’ biological clock will be re-adjusted, making it harder for them to get up on time. Therefore, the absence rate would be decreased again.
In summary, compared to making classes late in the morning, starting the day early would bring many benefits in learning. Students would be able to maintain a healthy life physically and mentally, and to explore in study, all of which contribute to a higher quality of learning.
In the contemporary society, the length of study time on the part of students has become one of the most hottly debated issue among the general public. When it comes to whether students should be required to arrive school at the early time in the morning, people’s notions may vary from one to another. In my eyes, starting school day at a late time is a better choice for the following reasons.
To begin with, arriving school at the late time will ensure students have a good rest and thus contributes to the improvement of their study efficiency. As is common sense, the increasingly heavy study burden on the shoulder of students has squeezed their leisure time so much that their sleeping time cannot be guaranteed. As a result, with the implementation of starting school day in a late time, the quality of their rest will be improved, with the consequence that their attention will be more concentrated in class. On the contrary, shortening their rest time by requesting students begin class early will definitely produce a negative effect on their study. To be specific, it will be common to observe that students feel so sleepy as to have a short nap during the class.
In addition, students who start school day in a late time will obviously avoid being stuck in traffic jam and thus have a better mood in the morning. Undoubtedly, under the drive of a cheerful frame of mind, children will raise their efficiency of study to a large extent. The experience of my cousin, Tom, can serve as a good example to shed some lights on the above reasoning. Tom, a student in a middle school of Beijing, used to be required to arrive school at 8 a.m. every morning in order to prepare better for the National Examination of College Admission. However, the problem is that according to the regulations of most companies, employees also have to start work at 8 a.m. Therefore, it is not hard to imagine that the subways, buses and taxis are crowded with people in the morning. According to Tom’s recounting, no one will feel good after such a experience, let alone immediately devoting him/herself to study.
Taking what has been discussed into consideration, we can draw the conclusion that it is wise to require student to arrive school at a late time in the morining, in order to ensure the quality of their rest and develop a light heart.
Have you experienced struggling with your pillow every morning? Have you ever choked with the traffic jams in the rush hour? Have you ever felt sleepy in the first class? No matter what scientific evidence shows us the advantages of having class early, there is a new research from Mark Fischettiof Scientific America convince us that students' efficiency can be improved by going to school later. I totally agree with the statement for it’s beneficial for both of students and teachers.
First, students' efficiency can be elevated. Under the excessive burden, students always stay up late and that’s why their sleep time has been shrunk. If they are forced to get up early, their whole day will be windy. Thus, students would waste the most substantial content of study, nevertheless, students would be more fresh and have concentrations on the class. According to Kyla Wahlstrom, director of the Center for Applied Research and Educational Improvement at the University of Minnesota. She made a research in Minnesota February that tracked 9000 students in eight public high schools in Minnesota, Colorado and Wyoming. After one semester, when school began at 8:35 a.m. or later, grades earned in math, English, science and social studies typically rose a quarter step—for example, up halfway from B to B+. This conclusion perfectly convinces everyone that students should get up later.
Second, we should follow students' biological system. Adolescents' physiology has greatly altered from their childhood because of melatonin. The later the delay, the greater the payoff.Following their biological change can make them healthy and wealthy. Take me as an example, as a teacher, most of my students would like to finish their homework and chat with friend until the mid night. They can't control their biological clock, which makes they fell very sleepy in the first class. Moreover the rate of being on duty is lower compared with other time periods.
Third, traffic problems can be released. One should know that big cities have the traffic jams all the time, which makes students choked with the road and can’t get rid of it. Moreover, students who live far away from the school are hurry to get catch up with the early classes. If schools postpone their time to be later, it will help them stagger the rush time of traffic. Nevertheless, students would start their study restlessly, which influences their mood not mention to the study efficiency. A study in 2012 from California public schools shows that students can avoid transportation problems by changing their class time. What’ more, their literature and math scores are higher on the average.
To conclude, getting up early and attend class are good for both of students and teachers. I suggest that school should postpone their class time and improve students’ efficiency.
Some people believe that video games could inspire young students' interest and make their study more efficient rather than distracting them and a waste of time, so young students should be allowed to play video games.
Many parents with young children fret about the addictiveness of computer games these days. While the negative effects ranging from addiction, increased aggression and various health consequences such as strain injuries get far more media coverage than the positives, there is now a wealth of research which shows that video games can actually be put into educational use and affect the brain's development
Firstly, games that are designed to help teach and "brain training" have long and enormous popular appeal. According to an experiment conducted by the University of California, game players show improved performance in perception, attention and cognition. One of the redeeming qualities of all games, even those with violent content, is enhanced information-processing, logic-thinking and problem-solving abilities in novel contexts. In fact, while playing game, your brain is in the learning mode constantly, to move to the next level, you are vigorously improving your hand-eye coordination, enhancing split-second decision making and boosting auditory perception. Moreover, other carefully-designed studies have shown that video games improve several aspects of brain activity, including multitasking. Considering Pac-Man as an example, in that game, you must navigate your character through a spatial layout while monitoring the separate paths of four additional objects, while keeping the overall goal of clearing the small pellets in memory, as well as keep track of the remaining large pellets.
Secondly, games that convey positive social messages never fail to boost the children's confidence, encourage cooperation and teamwork. Games help children feel a sense of achievement, through those puzzles, exploration and discovery, players learn to succeed in ways that our brains actually prefer. Most games are designed to introduce a new concept and then provide players with an opportunity to master it. Children are then free to explore and utilize and achieve success with this new skill, growing in confidence all the while. Besides, many games today emphasize the cooperative aspects of game play, in which two or more players need to work together to reach a common goal. Taking a game called "World of Warcraft" as an example, children as young as 10 years old are learning to delegate responsibility, promote teamwork and steer groups of people toward a common goal. As video games themselves are not created by just one person, it is essential for the game players to pool everyone's talents together in order to require the desired product.
Admittedly, it is worth to consider the real concerns that today's parents have with video games, but it is also worthwhile to consider the benefits and positive aspects that contemporary interactive entertainment choices provide. Digital media such as computer games could inspire young children's interest, grow their intelligence and offer them a chance to escape from the mounting academic stress, as long as coupled with strong parental and teacher involvement.
From all the discussions mentioned above, we may safely draw the conclusion that today's young students should be allowed to play computer games for the tremendous benefits they bring.
