When we are faced with them, nothing is more important than having hope and self-confidence.With confidence, we can find sometimes the question is not as “huge” as we imagine.Take most of us for example, the entrance exam to college seems to be a horrible monster.Accordingly, some people give up, some persist.In my eyes, with confidence, right assessment of the difficulties, as well as full preparation,try our best, and then we will overcome all problems and challenges.On the whole, I believe we youngsters should face the difficulties in right manner.And nothing is impossible, brave it out（拼命干）and just do it!

二、转换法
在词性不变的情况下，英语中一个单词由一种词性用作另一种词性，称为转换法。
构词法第 1 页（共4页）
1.动词转化为名词。
很多动词可以转化为名词，大多数情况下，意思没有多大变化。如： Let’s go out for a walk.Let me have a try.We stopped there for a swim.He is a man of strong build.2.名词转化为动词。
英语中，很多表示物体、身体部位等的名词及某类人的名词，可以转化为名词。如： Since graduation, I have authored 34 nationally published children’s books.It can seat 1000 people.Please hand me the book.She nursed her husband back to health.3.形容词转化为动词。
英语中，少数形容词可以转化为动词。如：
The promoters of such products say they can shape the legs, slim the face, smooth wrinkles.The train slowed down to half its speed.This will help warm up the soil.4.形容词转化为名词。
英语中，表示颜色的形容词常可以转化为名词。如： You should be dressed in black at the funeral.某些形容词如old, young, poor, rich, wounded, injured等与the连用，表示一类人，作主语时，谓语常用复数。如：
The old in our village are living a happy life.考点

left happily.The boy never came back after he picked the apples.The tree was sad.One day, the boy returned and the tree was so excited.“Come and play with me,” the tree said.“I don’t have time to play.I have to work for my family.We need a house for shelter.Can you help me?”“Sorry, but I don’t have a house.But you can chop off my branches to build your house.” So the boy cut all the branches off the tree and left happily.The tree was glad to see him happy but the boy never came back since then.The tree was again lonely and sad.One hot summer day, the boy returned and the tree was delighted.“Come and play with me!” the tree said.“I am sad and getting old.I want to go sailing to relax myself.Can you give me a boat?”“Use my trunk to build your boat.You can sail far away and be happy.” So the boy cut the tree trunk to make a boat.He went sailing and never showed up for a long time.The tree was happy, but it was not true.Finally, the boy returned after he left for so many years.“Sorry, my boy.But I don’t have anything for you any more.No more apples for you...” the tree said.“I don’t have teeth to bite,” the boy replied.“No more trunk for you to climb on.”“I am too old for that now,” the boy said.“I really can’t give you anything...the only thing left is my dying roots,” the tree said with tears.“I don’t need much now, just a place to rest.I am tired after all these years.” The boy replied.“Good!Old tree roots is the best place to lean on and rest.Come, Come to sit down with me and rest.”
The boy sat down and the tree was glad and smiled with tears...This is a story of everyone.The tree is our parent.When we were young, we loved to play with Mom and Dad...When we grown up, we left them, and only came to them when we need something or when we are in trouble.No matter what, parents will always be there and give everything they could to make you happy.You may think that the boy is cruel to the tree but that’s how all of us are treating our parents.****************************************************************************** Take time out during the day for quiet time to listen to your inner voice.You may want to use your quiet time to meditate or pray.However you use this time, the key is to shut out all of the noise around you by focusing deep within yourself.Breathing deeply during quiet time will also help you focus.I know it’s hard to find quiet time during a particularly busy day, but it’s so important — even if it’s just 10 minutes a day and you have to sneak away to get it.Quiet time can really make a difference in your life.It enables you to hear God speaking to your heart reminding you of His perfect love for you.Be honest with yourself by paying attention to your actions.Actions speak louder than words, and they always tell the truth.What do your actions say about you? If you say you love your job, but your actions say otherwise, which do you think is more true — your words or your actions? On the other hand, if you say you’re not good at a certain job, but your actions say otherwise, that’s also important.What do you do with this insight? You can use it to make more beneficial choices in your life.By being honest with yourself based on your previous actions, your actions moving forward will be based on truth instead of just what you tell yourself.Despite what your subconscious may be telling you, you can have love with no limits.The key is to unconditionally love yourself first.The Apple Tree参考译文
苹果树
很久很久以前，有一棵又高又大的苹果树。一位小男孩，天天到树下来，他爬上去摘苹果吃，在树荫下睡觉。他爱苹果树，苹果树也爱和他一起玩耍。
后来，小男孩长大了，不再天天来玩耍。一天他又来到树下，很伤心的样子。苹果树要和他一起玩，男孩说：“不行，我不小了，不能再和你玩，我要玩具，可是没钱买。”苹果树说：“很遗憾，我也没钱，不过，把我所有的果子摘下来卖掉，你不就有钱了？”男孩十分激动，他摘下所有的苹果，高高兴兴地走了。然后，男孩好久都没有来。苹果树很伤心。
有一天，男孩终于来了，树兴奋地邀他一起玩。男孩说：“不行，我没有时间，我要替家里干活呢，我们需要一幢房子，你能帮忙吗？”“我没有房子，”苹果树说，“不过你可以把我的树枝统统砍下来，拿去搭房子。”于是男孩砍下所有的树枝，高高兴兴地运走去盖房子。看到男孩高兴树好快乐。从此，男孩又不来了。树再次陷入孤单和悲伤之中。
一年夏天，男孩回来了，树太快乐了：“来呀！孩子，来和我玩呀。”男孩却说：“我心情不好，一天天老了，我要扬帆出海，轻松一下，你能给我一艘船吗？”苹果树说：“把我的树干砍去，拿去做船吧！”于是男孩砍下了她的树干，造了条船，然后驾船走了，很久都没有回来。树好快乐……但不是真的。
许多年过去，男孩终于回来，苹果树说：“对不起，孩子，我已经没有东西可以给你了，我的苹果没了。”
男孩说：“我的牙都掉了，吃不了苹果了。” 苹果树又说：“我再没有树干，让你爬上来了。” 男孩说：“我太老了，爬不动了。”
“我再也没有什么给得出手了……，只剩下枯死下去的老根，”树流着泪说。
男孩说：“这么多年过去了，现在我感到累了，什么也不想要，只要一个休息的地方。” “好啊！老根是最适合坐下来休息的，来啊，坐下来和我一起休息吧！”男孩坐下来，苹果树高兴得流下了眼泪……
这就是我们每个人的故事。这颗树就是我们的父母。小时候，我们喜欢和爸爸妈妈玩……长大后，我们就离开他们，只在需要什么东西或者遇到麻烦的时候，才回到他们身边。无论如何，父母永远都在那儿，倾其所有使你快乐。你可能认为这个男孩对树很残酷，但这就是我们每个人对待父母的方式。
****************************************************************************** 白天花些时间出去，独自倾听自己的心声。你可能想利用这段安静的时间沉思或祈祷。无论如何利用这段时间，关键是要排除周围所有的噪音，关注自己的内心深处。安静的时间进行深呼吸也能帮你集中注意力。我知道在特别忙碌的日子找到安静的时间很难，然而这很重要——即使一天只有10分钟，你也要溜开抓住它。安静的时间确实能使你的生命变得不同，它促使你倾听上帝与你的心灵对话，使你想起他赋予你的完美的爱。
坦诚对己，注重行动吧。事实胜于雄辩，行动才能证明事实。你的行动是如何说明你的呢？如果你说热爱自己的工作，而你的行动正好相反，你认为哪个更有说服力呢——言语还是行动？另一方面，如果你说不擅长某项工作，但你的行动正好相反，这也很重要。你怎么处理你这种能力？你可以由此在生活中做出更多的选择，坦诚对己也建立在以前的行为上，你以后的行动将会以事实为基础，而不只是你的言词。
不管你的潜意识告诉你什么，你都能够拥有无尽的爱，关键是首先你要无条件地爱自己。
构词法答案：
中考英语词法复习总结 篇4
1.掌握所学单词的形态变化，中考英语复习语法(词法Ⅰ)。
2.掌握简单句的五种基本句型，四笔头练习基本正确。
3.能理解不复杂的、含有状语从句或宾语从句的复合句。
4.掌握动词的五种基本时态(一般现在时、一般过去时、一般将来时、现在进行时、现在完成时)的基本用法。
5.能理解并初步掌握过去进行时、过去完成时和过去将来时的基本用法。
6.掌握一般现在时(包括含有情态动词的一般现在时)、一般过去时的被动语态的基本用法。
7.掌握动词不定式作宾语、宾语补足语和状语的用法(作主语和定语的用法只要求理解)。
【重难点问题归纳】
语法知识是在掌握一定量的单词和短语的基础上才能获得的。因此，单词的形态变化和简单句的五种基本句型是语法学习的基础之基础。五种基本时态和含有不复杂的状语从句及宾语从句的复合句是初中毕业班学生学习的重点也是语法学习的难点。五种基本时态中的一般过去时和现在完成时的基本用法及其区别是学习的难点。状语从句中的时态问题，宾语从句中的主语和谓语的语序问题是学生感到头痛的问题。被动语态是中国学生最不喜欢学习和使用的一种语态。因此，学生在学习时，时常感觉到很困难。动词不定式是初中英语语法中的一个重点。不定式在句中作宾语、宾语补足语和状语等用法均要求掌握，特别是一些动词，有些后面要求跟不定式作宾语，有些则要求跟动词一ing形式作宾语。
总之，语法部分是英语学习的重点和难点。语法知识掌握得好，将大大加快英语学习的进程。
【中考热点分析预测】
语法部分历年来是中考的必考内容。考试的范围广，涉及单词词形变化、基本句子结构、五种基本时态搬动语态、不定式用法以及状语从句、宾语从句，等等。近年来，在教学改革方面加大了对听说教学的力度，初中段以培养学生的交际能力为主，为高中段的英语学习打好基础，对语法知识的要求作了调整，降低了难度，但考查的范围并没有减小。单纯考语法知识的题比以前明显减少。试题往往设置一个情景，在对话中考查时态及基本句型。当然，有些语法项目设置在单句中，如：不定式、被动语态以及词语搭配。
语言学习是一个积累的过程，不记住相当数量的词语、习惯用语。句型和语法规则，是学不好英语的。因此，对词形变换、句型结构、状语从句中的时态以及常用的五种基本时态的考查仍将是中考命题的热点。
【应试策略】
