为了提高初一英语作文写作水平，平时应加强阅读，多背诵一些句形、段落甚至短文。俗话说：读书破万卷，下笔如有神，只有多读，多记，多背诵，才能出口成章，下笔成文。此外，写好初一英语作文还要掌握一些应用文体的写作方法，如书信、日记、通知等，它们大多有固定的格式。

二、认真审题，明确要求

在写初一英语作文的时候仔细看清写作要求和提示，分清材料的主次，接着确定体裁、格式和人物、地点等要素；最后确定时态，同时考虑相关的语态搭配用法。 三、遣词造句、表达规范

初一英语作文用词要恰当，不可逐句把提示翻译成英语。写作时，应尽量选用你最熟悉、最有把握的词和句型来表达思想。如果有些单词不会些，有些句型不会表达，可以设法绕开，用熟悉的同义词、同义短语或同义句来代替。要学会善于运用适当的关联词，如and, or, but, so，because, since等，以使初一英语作文行文逻辑紧密，自然流畅。 四、认真撰写，卷面整洁

初一英语考试中也会有初一英语作文题，如果时间允许，书面表达一定要先写草稿。在抄写入答题卷前，要先进行检查修改。首先检查所写内容是否切题；之后检查主题是否明确，表达方式是否恰当；最后检查所用时态、语态、人称是否符合要求，前后是否一致。 中考复习研讨会指导课件，极具价值。 关联词

Though the science is highly advocated, people try to explain everything in science, there are still some people believe that something happen for some certain reasons, and the ghosts manipulate the supernature.

In the older generation, they believe in ghosts so much, my grandma is one of them. She burns joss sticks day and night, she says if she keeps doing this, and the immortal will see her sincere and will bless our family fast and sound.

As for me, I don’t believe in superstition, a ghost exists in those people who do the guilty things’ heart. But if people believe in superstition and have faith, that will be good for them, so they won’t feel empty and do the right things.

虽然科学得到了高度的提高，人们尝试着用科学解释每一件事情，但是仍然有一些人相信事出是有因的，鬼魂在背后操纵着超自然现象。

在老一辈里，他们很相信鬼怪，我的奶奶就是期中一个。她从早到晚的烧香，她说如果她坚持这样做的话，神仙就会看到她的诚意，就会保佑我们家身体健康。

对于我来说，我不相信迷信，鬼魂存在于那些做了亏心事的人心中。但是如果人们迷信并且有信仰，这样对他们来说也是好的，这样他们就不会感到空虚，也会做对的事情。

The Importance of Details

"The devil is always in the details" is a proverb which means that details determine our success. Therefore, this quotation aims to tell us that every detail is important enough to be paid attention to.

Some people may think that one who wants to achieve great success shouldnt pay much attention to details，but those who desire to do something big at once will constantly be haunted by disappointment, frustration or even failures，as when something big " shows up，they can hardly seize the opportunity because of the lack of ability to deal with small things. Keeping an eye on details may help us in many ways. For instance, when we were small children, we were sometimes very careless and there were many lapses in our homework, but if we could pay much more attention to these trifles, we would get a higher mark in the exam. Whats more, when we make decisions, making every detail clear will reduce risks.

To sum up，under no circumstances should we undervalue the importance of details, for paying attention to small things is the first step of success and will lay root for doing something big.

At that moment, nature and me were united, we just like a group.

Directions: For this part, you are allowed 30 minutes to write a short essay entitled Goal Setting Is Important by commenting on John Ruskins 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 todays 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.

Whether you handed a cup of warm tea after your parents were tired, handed a card on their birthday, and greeted and comforted them when they were lost.

Self-confidence, as is approved by research and practice, has an amazingly powerful influence on the output of people’s activities. Patients who believe that they’ll recover soon generally cures faster than those who think they won’t. Students with optimistic characters usually provide better performance, even if they work the same hard as others. Although someone may regard such conclusion as superstitious, it does take place everyday and everywhere. Neural scientists have discovered that, when a man feels confident, his brain will secrete some kinds of hormone that boost brain activity and improve the efficiency of his immune system. In contrast, a melancholic brain is suppressed by other chemicals and cannot fully exhibit its potential.

To help building up self-confidence, you can take the following two steps. First, identify your merits and value them. If you constantly compare your weakness to others’ advantages, you’d only gain frustration rather than confidence. Second, track every little progress you’ve made and review them frequently. You may not possibly become perfectly

successful in one day, but if only you can see yourself growing gradually, surely you’re on the right way.

There’re also other methods making you more confident that depend on yourself to find out, and they’re all necessary elements to make you more competitive in your area.

The traditional East Asian calendars divide a year into 24 solar terms (節氣). Lìchūn (pīnyīn) or Risshun (rōmaji) (Chinese and Japanese:立春; Korean: 입춘; Vietnamese: Lập xuân; literally: "start of spring") is the 1st solar term. It begins when the Sun reaches the celestial longitude of 315° and ends when it reaches the longitude of 330°. It more often refers in particular to the day when the Sun is exactly at the celestial longitude of 315°. In the Gregorian calendar, it usually begins around February 4 and ends around February 18 (February 19 East Asia time).

Lichun signifies the beginning of spring in East Asian cultures. Chinese New Year is celebrated around this time. Farmers often celebrate the beginning of Lichun with special village events, worship and offerings to the gods and ceremonies for a blissful and prosperous new year. In China, people eat chūnbǐng (春餅) on this day.

In the lunisolar calendar, New Years Day might be before or after Lichun. A year without Lichun is called 無春年 (no spring year). 無春年 is also known as 寡婦年 (widow year) in northern China or 盲年 (blind year) in southern China. Marriage is believed to be unlucky in a year without Lichun.

In the Republic of China, Lichun has been Farmers Day since 1941.

传统的东亚日历将一年划分为24节气(節氣)。Lichūn(pīnyīn)或Risshun(rōmaji)(中国和日本:立春;韩国:입춘;越南:Lập宣,字面意思:“春天的开始”)是第一个节气。开始当太阳到达黄经315°,结束时达到330°的经度。更经常特别是指一天太阳黄经的正是315°。公历,一般在2月4日开始和结束在2月18日(2月19日东亚时间)。

People always attach the importance to the promise, they hate people who break their promise. I remember once a time, my friend asked me to go to see the movie with her, I said yes without hesitation.

My friends called me, she asked why did I disappear, I said I was sleeping at home, she became very angry, until then did I think about our date. I felt so sorry, I break my promise for the first time, I realize I did the very bad thing.

Even though I apologized for many times, my friend was still angry with me. I learn the lesson, promise is very important, we must keep it, other people will see through our personality to decide what kind of person we are.

After 5.12 earthquake struck sichuan province since 2008, we, I was so frightened by an earthquake, I felt the earthquake many houses will be apart, can let many people lost their lives, is one of the worlds most terrible disaster. Today I saw "China childrens encyclopedia, really know anything about earthquake.

It turns out that the earthquake happened all of a sudden the vibration phenomenon, like the wind, rain, is a kind of common natural phenomena. Vibrations in the earth, in fact, very frequently, probably every 30 seconds there will be time, but most of them are very ease, people did not feel. We can feel the earthquake is due to the relative movement between earths tectonic plates, rock is squeezed, produce a huge amount of energy to make rock failure in an instant, or make originally the already existing fracture activity, suddenly release a large amount of energy, and some of the energy to the earths surface, make the earth trembling violently, causing strong earthquake. Started happening earthquake site is called the source, the source above the ground is called the epicenter, the ground of the devastating earthquake is the most strong place is called the magistoseismic area, while the magistoseismic area often is the place where the epicenter. When the earthquake occurred, the source of shock wave in the earths crust to all directions called seismic waves. Seismic waves hit the ground, the result will be a disaster.

We Chinese people are very smart, as early as the eastern han dynasty, there is a man named zhang heng scientists invented to measure the earthquake Hou Feng seismograph, and our modern scientists are generally measured the spread of seismic wave speed with the help of a seismograph, the place and time of the earthquake.

Know the earthquake knowledge, learning even before the earthquake early warning and self protection method, I think, to know that knowledge is very useful for our own.

自从2008年我们四川发生5.12大地震之后，我就特别害怕地震，我觉得地震会震垮很多房屋，会让许多人失去生命，是世界上最可怕的灾难。今天我看了《中国少年儿童百科全书》后，才真正知道地震是怎么回事。

原来，地震是突然间发生的大地震动现象，就像刮风、下雨一样，是一种很普遍的自然现象。地球上的震动实际上非常频繁，大概每30秒种就会有一次，但大多数都非常缓和，人们都没有感觉。我们能感觉到的地震是由于地球板块之间产生相对运动，岩石层受到严重挤压，产生巨大的能量使岩石在瞬间发生断裂，或者使原来已经存在的断裂突然活动，释放出大量能量，而其中一部分能量传到地球表面，使大地剧烈地颤动，从而引起强烈地震。地震开始发生的地点称为震源，震源上方的地面称为震中，破坏性地震的地面最烈处称为极震区，而极震区往往就是震中所在的地方。地震发生时，震源发出的在地壳中传向四面八方的冲击波称为地震波。地震波冲击到地面，就会引发灾难。

我们中国人非常聪明，早在东汉时期，就有一位叫张衡的科学家发明了用来观测地震的侯风地动仪，而我们现代的科学家也一般都借助地震仪来测量地震波的传播速度，判断地震发生的地点和时间。

知道了地震知识以后，还要学习地震发生前的提前预警和自我保护方法，我想，了解到这些知识对我们自己是非常有用的。
