P4 3c Now write about yourself

Five years ago, I was in No.1 Wuyi Primary School which is very close to my home. It took me only five minutes to walk there. I played tennis in my school team, because it could not only make me relax, but also reduce my pressure. I also had a cute hamster with creamy fur and thinking black eyes.

Today, I’m in Jianhua Middle School with a splendid history. There are many friendly classmates and patient teachers. I play golf in order to have a healthy lifestyle. I have a computer because in my free time, I like talking with my friends online and surfing the Internet.

In five years, I will be in a college. I’m willing to go abroad to finish my college. I’ll play the guitar, because it’s really cool. I’ll have a part-time job in order to get some valuable experiences for my future job.

People will use the subways more, so streets will be quieter.

There will be more trees and flowers, so cities of tomorrow will be more beautiful.

Robots will do housework, so people will have more free time to relax.

The world will be more colorful and mysterious beyond our imagination.

(世界将变得更加多彩和神秘,超出我们的想象.)

写作实操

In ten years, I will be a teacher. I will live in Shanghai because I went to Shanghai last year and fell in love with it. As a teacher, I will teach kids not only how to study, but also how to help others, how to build correct values and how to get on well with each other. I will help kids open up their eyes to the outside world. If I become a teacher, I’ll be happy. I’m sure I will be a friendly teacher and I will be good to kids like their sister or brother. As for my hobbies, I like playing sports and listening to the soft music because they are good ways to relax. I’ll dress some clothes which can make me look beautiful and smart. I hope I can do something I love and my life will be wonderful.

In ten years, I will be a writer. I love writing and I can always get some good ideas. And writing is also a relaxing job. I can just take something to write with, sit anywhere, make myself a cup of coffee to drink or just pour all my ideas on the paper or screen. As a writer, I will travel a lot of places to experience and explore local custom, culture, history, geography, etc. At the same time, I will make friends with local people. What’s more, a good book is not only worth a lot of money, but also good for our soul. It will be good if I can get a house in the countryside. I don’t need special clothes t o be a writer. And I’m sure if I become a writer, I’ll enjoy my life.

作文(Unit2 P12 4 )problem1

Jim, a Canadian boy, has come to live in China with his parents. He wants to practice his Putonghua, but he is very shy. Please write him a letter and give Jim some advice that may help him.

审题:shy Putonghua

Being shy is a result of a lack of confidence.

Practice makes perfect. You should practice as much as possible. Take a moment to admire the work you’ve done. You have a good reason to feel proud.

It is important that you realize your performance does not have to be perfect.

Make sure you don’t keep your talent inside.

You should practice Putonghua in front of the mirror or your family.

You’d better make some Chinese friends at your age.

If I were you, I would be a volunteer teacher to teach little Chinese kids English. By the way, I would chat with them without any embarrassment and shyness.

I'm very glad you'll come to Beijing to learn Chinese. I think Chinese is very useful. Many foreigners are learning Chinese now. Chinese is different from English. So it is very hard for you to learn it well. Don't worry. I have some suggestions for you to learn it well. First, I think studying Chinese by watching Chinese movies is a good way because you can improve your listening skills. Also, you can join a club. If you join a club, you will make many new friends and practice your spoken Chinese. Second is reading. Reading English books is too

difficult for me. So I think it's difficult to read Chinese books as well. You can read something you like. Even

though you don't like to read Chinese, you have to do it. Because I think reading is so good for writing. Third, I think you can find a Chinese pen pal to practice your writing. You can also keep a diary in Chinese every day.

Hope to see you soon in Beijing.

Problem2

Dear Mary,

I have a problem, and I need your help. I always thought I was popular at school. But I just found out that my friends were planning a birthday party for my best friend, and they didn't invite me. Everyone else in my class was invited except me, and I don't know why. I can't think what I did wrong. I am very upset and don't know what to do. What do you think? Can you help me?

suggestion

Maybe it doesn't mean that he doesn't like you. Maybe he forgot it carelessly. Ask yourself. Is he friendly? Is it fun for you to join the party? If your answer is yes, you could take with your friend and tell him you have prepared a gift. By the way, you'd better ask why.

Try being yourself, no need to follow the crowd. Maybe you could go to a movie or do what you like and don‘t mind it

I’m sorry to hear that there are some problems between you and your cousin. I hope I could give you some suggestion that may help you. Everyone has problems. First you could have a heart-to-heart talk with her honestly. If you express y our real feeling, I’m sure she will understand you. In addition, it’s a good way to still get on well with her,

though she has her own shortcomings.

After all, for the past few years, you two have been really good friends. In fact, if I were you, I would tell a white lie like “I can’t find that book.”

It wouldn’t mean hurting anyone, however, it’s perhaps the best solution. But if you truly insist on not telling a lie, you’d better set a bottom line of the time she should return things before you l end your things to her.

I’m looking forward to your good news.

Problem3

As a Chinese student, I agree that "Students should be given more free time." because it's not easy for most of us to have fun in our lives.

I often face cruel competition and in fact, I'm under pressure. I have to study hard and do much homework

every day. I feel so tired now. But my parents and teachers always think that if I have more free time, I will

concentrate more on my interests than on my studies. I don't think so. I think I can do something I like and get

more knowledge in my free time.

In a word, I think it's important and necessary for Chinese students to have more free time. It's good for our healthy growth.

suggestion

I’m sorry to hear that you h ave an unhealthy life. You are a middle school student at my age. I think you should know that junk foods are bad for your health, and eating more vegetables will help you to keep fit. If you

become too heavy, it will cause many problems. So you’d better s top eating junk food and do more exercise. Well,

Internet can be helpful too if you use it in a right way. However, spending too much time on-line is kind of waste

of time . Finally, as study is always our duty, you should make yourself be more interested in reading or

something like that. If I were you, I wouldn’t let my mom feel worried about me.

I’m looking forward to receiving your good news.

If you make your feeling inside it, it can even make you feel sick.

If you think you’ll have trouble saying what’s on your mind, write it down on a piece of paper instead.

Sharing also helps you to get closer to people who you care about and who care about you.

First, you should pay attention in class. It’s a good start for learning. It will help you lea rn more and faster. Try to keep your mind focused.

Second, Taking good notes can make it easier to study.

Third, planning ahead can help you get good grades. You could plan what to do and how much to do each day.

Planning is part of being organized.

Finally, if I were you, I would ask teachers for help. You could also ask some other people, like your classmates or your mom or dad.

It was eleven o’clock when Christina went to a park with her new pink bike. The weather was lovely, quite like what the guys said about her: bright, temperate and lovely. The bike seemed to be enjoying the weather too. It was a brand new pink bike with the sign “a nice girl” on it. It was an efficient bike which was the girl’s favorite. It was quite expensive too.

It was 11:10. There was a beautiful lake in the park. Some boys were swimming and playing water polo in the clean water happily. Fishes looked up and steered at her with their big bubble eyes.

But the only disappointing was that Christina’s boy friend was late. She was enjoying the beautiful scene, wait ing and waiting. Gentle breeze wiped away all her sadness and unhappiness.

But just at that very time, which was around eleven-fifteen, a boy pocked his head out of the bushes and saw the bike. “Look, what I’ve found! ” he thought, “my girl friend would love this bike! But how can I get this? It looks so expensive.” he decided to steal it. Unfortunately, Christina didn’t notice it.

Ten minutes later, Christina decided to go home, but she couldn’t find her bike! She got really nervous and upset, so she

called her boyfriend. “Hey, Chrissie! ” A boy’s voice answered the phone, but all he could hear was a girl choking on her own tears.

“What happened?” he asked anxiously.

“I…I lost my new bike.” Christina answered.

“What does it look like? I’ll get there and look for it for you.”

“Well, it’s a brand new pink bike, I just bought it yesterday.”

At 11:25, she was waiting for her boy friend beside the bushes.

At 11:00 o’clock in the morning, Mary was riding her pink bike to a beautiful park which is famous for its green leaves. She really wanted to relax on such a lovely day.

Ten minutes later, she got to the park and put her bicycle beside some bushes. In front of her was a beautiful lake where some boys were swimming there. She was enjoying the golden sunshine and blue water. Unfortunately, she forgot to lock her new bicycle. The new pink bicycle was shining in the bright sunshine. A man who was hiding in the bushes really wanted to get it.

At 11:15, He looked around everywhere to make sure that nobody noticed him, then he jumped out of the bushes and stole the bike while the girl was walking down the road leisurely. He ran away as quickly as possible.

Ten minutes later, the girl decided to go home, but she couldn’t find her bike anywhere! Nervous and upset, the girl was crying loudly . She had to call the police in the hope of finding the bicycle.

Maybe I’ll be a lawyer. If I become a lawyer, I’ll be able to help people. But I won’t be able to work outside and I won’t be able to work with children.

So I think I will be a teacher.

We often focus on building relationships with others that we forget the essential first step:

being friends of ourselves. That is the crucial first step if we are to have good relationships with others.

How can we have good relationships with others it we don’t even have a good relationship with ourselves?

The problem might be worse than we expect. Maybe we don't like ourselves without realizing it. Here is a simple checklist; is there anything you don't like about yourself from these list?

·Your past

Maybe you have made mistakes in the past which you feel bad about. You might be disappointed with yourself on why you could make such mistakes. Even it that happened in distant past, your subconscious mind still has a reason not to like yourself.

·Your background

You might wish that you were born in a different family, or that you have a different background. Maybe you could not accept the fact that you are not as lucky as others, who seem to get whatever they want effortlessly because of their background.

·Your personality traits

You might have some personality traits that you don't like. For example, you may be an introvert and you don't like it; you wish you are an extrovert.

·Your achievements relative to others

Others might have better achievements than you, and no matter how hard you tried, it might seem impossible for you to match them. You might then think that it's because you are not smart enough or don't have enough talents.

Is there anything that resonates with you? All these give reasons to you not to like yourself. That in turn makes it difficult for you to be a good friend to yourself. Fortunately, there are always things you can do to fix the situation. Here are some tips:

1. Forgive yourself

You may have made those mistakes in the past, but is there anything you can do about them? I don't think so, except learning from them. It's true that you are not perfect, but neither is everybody else. It's normal to make mistakes, so do yourself a favor by giving yourself forgiveness.

2. Accept things you can't change

There are some things you cannot change, such as your background and your past. So learn to accept them. You will feel much relieved if you treat things you can't change the way they deserve: just accept them,

smile, and move on.

3. Focus on your strengths

Instead of focusing on your weaknesses, focus on your strengths. You always have some strengths which give you a unique combination nobody else have. Recognize your strengths and build your life around

them.

4. Write your success stories

One reason we may not like ourselves is we are too focused on what we don't have that we forget about what we have. So make a list of your achievements; write your success stories. They do not have to be big things; there are a lot of small but important achievements in our life. For example, if you have some good friends, that's already an achievement. If you have a good family, that is also an achievement.

5. Stop comparing yourself with others

You are unique. You can never be like other people, and neither can other people be like you. The way you measure your success is not determined by other people and what they achieve. Instead, it is determined by your own life purpose. You have everything you need to achieve your life purpose, so it's useless to compare

yourself with others.

6. Always be true to yourself

You don't like other people lying to you, right? Similarly, you won't like yourself if you know that you lie to yourself. Whether you realize it or not, that gives your mind a reason not to like yourself. That's why it's

important to always be true to yourself. In whatever you do, be honest and follow your conscience. Remember this quote by Abraham Lincoln:

I desire so to conduct the affairs of this adm inistration that if at the end… I have lost every other friend

on earth, I shall at least have one friend left and that friend shall be down inside of me.

?Most people would like to be popular with others, but not everyone can achieve this goal.

?What is the secret to popularity? In fact, it is very simple. The first step is to improve our appearance.

We should always be in good shape and dress well. When we are healthy and well-groomed, we will not only look better but also feel better. In addition, we should smile and appear friendly. After all facial expression is an important part of our appearance. If we can do this, people will be attracted to our good looks and impressed by our confidence.

?Another important step is to be a nice person. We should be honest and care about others. We should always think about others first and place their interests before our own. What’s more, we also need to be good listeners; in this way people will feel comfortable enough to confide in us. However, no matter what we do, we should not gossip(爱说长道短). Only by being sincere(真诚的) and respectful of others(尊重他人) can we

earn their respect.

?If we can do all of the above, I am sure popularity will come our way.
