Everyone has a school bag, but mine is different!

My bag is sometimes happy, and it should be filled with infinite knowledge in my head. Whenever I carry it to school with the morning sun, I always feel that every morning is so beautiful, and it seems to say, "Come on, come on, a new day and a new beginning." ”

My bag is sometimes angry, probably because I make it a mess! Maybe I didn't get anything out of the day! At this time, it seems to say: "The sun and the moon are like a shuttle, we must use the good time of each day to gain more knowledge, and we can't "wait for the rabbit"! ”

My schoolbag is sometimes sad and sad because I didn't do well in the exam, which makes it disappointed and sad. Somehow, I was a little nervous in every exam, afraid that I would not do well in the exam, but the more this happened, the worse the exam, so the first place in the grade of the monthly exam was reduced to the sixty-ninth place in the mid-term exam, at this time, it would say in a sad and comforting tone: "I don't do well in the exam, it is caused by not being active and not working hard, I must work hard in the future, don't be nervous about the exam."

Remember, when doing the usual practice paper, treat it as if it were a final exam paper; When it comes to the actual exam, treat it as a small practice paper, and in this way, you will be well equipped in the ocean of study! ”

My bag is sometimes joyful. Because when I am praised or when a teacher entrusts me with something, it is happy, joyful. I asked it why.

It straightened up and said proudly, "The teacher praises you, which means that you have done a good job; The teacher gives you things to do, which means that the teacher trusts you. "Oh, I see.

Look, isn't my bag very exciting? It's always a reminder of what to do, and I love my bag.

Nanjing Yangtze River Bridge.

The Yangtze River is connected to the north and south, and the distant water floats through the ancient and modern. In December 1968, the Nanjing Yangtze River Bridge, the first double-decker railway and highway dual-purpose bridge designed and built by China on the Yangtze River, was fully completed and opened to traffic, and was listed in the "Guinness Book of World Records" as "the longest road-rail dual-purpose bridge".

The Nanjing Yangtze River Bridge is located in the lower reaches of the Yangtze River.

The railway bridge on the lower level is 6,772 meters long and 14 meters wide, paved with double tracks, allowing two trains to cross at the same time. The main bridge is 1577 meters long, which is the largest bridge in China.

The railings on both sides of the main bridge are embedded with 200 cast-iron reliefs. There are two bridgeheads of 70 meters high at the north and south ends, there is an elevator in the fort, and there is a sculpture of workers, peasants and soldiers with a height of more than 10 meters in front of the fort.

Introduce your object, say its appearance, color, function, and add some beautiful words!!

It is sufficient to write about the shape and function or function of a physical object. To give you an example reference, tomatoes are also called tomatoes. Because of its bright color, fruit juice, sweet and sour, nutritious, and unique flavor, it is deeply loved by everyone.

I also love tomatoes and ask my mom to bring me a tomato or two almost every day when she buys groceries. I think there are five reasons why tomatoes are so popular. First, the color of the tomato is very bright, the surface is red, the red is so bright, so cute, so delicious, you are sure to be hungry as soon as you see it.

The second is its delicious taste, whether it is eaten raw or cooked, it always tastes sweet and sour, which makes people have a great appetite. Thirdly, it is its light fragrance, if you put your nose close to it, you will smell a unique fragrance of tomatoes, which seems to be mixed with sweet and sour taste. Fourth, it is the shape of the tomato, speaking of the shape of the tomato can be described as strange, some like a red pumpkin, some like a red baby face, and some can't say what it looks like.

Secondly, the nutritional value of tomatoes is also a lot, and tomatoes contain more calcium, phosphorus, iron, carotene, vitamins, nicotinic acid and other nutrients than many vegetables. Traditional Chinese medicine believes that tomato is sweet and sour, slightly cold, has the effect of strengthening the spleen and appetizing, quenching thirst, etc., and can be used medicinally for loss of appetite, fever, heatstroke, thirst and other symptoms. From this point of view, tomatoes have a lot of effects!

Tomatoes are both a delicious fruit and a nutritious vegetable!

First of all, you can explain the characteristics of your thing in the first natural paragraph, then write its appearance (appearance) in the second natural paragraph, write its characteristics (characteristics) in the next few natural paragraphs, and finally summarize. (Refer to Lesson 10: Squirrels, insert a column of numbers, give examples, make comparisons, hypothesize, and define .......)）

Everything has its own characteristics, and it is a sign that distinguishes it from other things. When writing an expository essay, only by grasping the characteristics of things can the explained things be accurately and clearly introduced to the readers, so that people can have an accurate understanding of things. To grasp the characteristics of things and to write is to grasp the center of the explanation.

Of course, things often have many characteristics, and it is impossible to cover them in an expository essay, so you can only talk about one or two characteristics at a time as needed. For example, ducks and chickens are both poultry, they can walk, they both have wings, and they can both make meat.

Fear of harming the plate.

The fan's self-report.

When it comes to me, everyone must be familiar with me. Since ancient times, I have been an indispensable summer relief for people, and some of them are exquisite handicrafts! "The cool world comes from the hands; Fine, ingenious. This is a poem written by the poet Guo Moruo in praise of me.

Don't look at my small body, I'm not young. As early as more than 3,000 years ago, in the Yin Shang era, I was born. It's just that at that time, I didn't belong to the heat, but as an ornament.

For example, the ancient emperors traveled without me. As for me, it is made of the feathers of rare birds, which are used to shield them from the sun and dust, to show their majesty. In the Han Dynasty, my use was also very common, and there were many types, such as yarn fans, silk fans, Luo fans, silk fans, etc.

After the Wei and Jin dynasties, my form was constantly updated, with stacked fans, waist fans, square fans, round fans, hexagonal fans, etc., each with its own characteristics and exquisite. In order to make me more beautiful, people have taken a wider range of materials, and they have matched me with gold, silver, jade, agate, jade, etc. In recent years, many members of my family have become well-known at home and abroad, such as sandalwood fans in Suzhou, bamboo silk fans in Zigong, Sichuan, and silk fans in Hangzhou.

Now, my family is huge, with hundreds of varieties. I am colorful and loved by people.

In addition, I have a variety of uses. In addition to being practical, I can also be used as a work of art. I have a very close relationship with literature, calligraphy and painting, opera, dance, etc.

The ancient literati and Danqing saints inscribed poems and paintings on my body: many people also regarded me as a gift and gave them to each other. There are also many poems and songs that praise me.

For example, "the silver candle autumn light cold painting screen, light Luo small fan fluttering fireflies", "there is no wind without moving, there is no wind without moving" and so on are my famous sentences. I used it as a song and dance prop in the Han Dynasty. In the traditional repertoire, I am often a prop for actors to express their feelings and portray the characters' personalities.

For example, the goose feather fan in Zhuge Liang's hand in the masterpiece of classical literature "Romance of the Three Kingdoms", which is even more interesting and funny, is unbearable.

In today's developed material civilization, although electric fans and air conditioners have entered the field of people's lives, because I have the characteristics of easy to carry, I still have an irreplaceable position in the hot summer.

Speech at the Spring 2009 Commencement Ceremony.

Dear teachers and students:

Good morning!

The breeze can't lock the flowing clouds, but the flowing clouds take away the years. "Time is always so poetic in the eyes of poets, yes! The years have turned another page, we have to wave goodbye to 2008, and we have to admit that the rings of our lives have grown by another year.

As Tao Yuanming said: "Be encouraged in time, and time will not treat others." Today, we Longhua people are standing on a new starting line.

In the early spring of February, it was warm and cold, but it was also full of spring. Spring is the first touch of green in the budding of willow silk, the first cry of migratory birds returning to the north, the first fragrance of peach blossoms, the first crisp sound of the river ice release, and the dawn of dawn that is pregnant with the hope that will be sprayed. As the saying goes:

The plan of the year lies in the spring. "Spring is the season of sowing hope, and it is the beginning of hard work and meeting challenges.

I remember a philosopher once said, "On the road of life, the greatest enemy you encounter is yourself." "For us, every fall, every illness, every loneliness is a challenge to ourselves.

Mencius said: "Heaven will descend on the people, and they must first suffer their minds, strain their muscles and bones, starve their bodies and skins, empty their bodies, act chaotically, and gain what they cannot." "We can only surpass ourselves by facing challenges.

In the summer of 2008, the hottest topic in the entertainment industry was "Supergirl", and "Supergirl" also led to a new term - "PK", "PK" is an opportunity, a competition, an elimination, and a challenge. And the "supergirls" are to grow up in challenges, surpass in growth, pursue excellence in transcendence, and finally stand out.

In fact, we are surrounded by challenges and opportunities. If you've never spoken in class before, why don't you try raising your hand? Why can't you jump out of the covers at the first bell in the morning?

I think that as long as we dare to challenge ourselves, we will definitely surpass ourselves.

Here, I sincerely wish that the students of Longhua School will dare to accept themselves, face themselves, find their goals, lay a good foundation, and continue to move forward in the new semester; May the seniors of junior high school be firm in their goals, persevere, and pursue their ideals without hesitation; May the high school seniors and seniors never give up in the final stage of the sprint, believing that "before dawn is the darkest hour". We firmly believe that you will leave a touch of brilliance in your life in Longhua and have a beautiful and brilliant tomorrow.

Here, on behalf of all the students, I would like to wish the teachers a smooth work, health and happiness; And sincerely wish that every one of us Longhua people can continue to surpass themselves and pursue excellence in the struggle. Thank you!

Dinner is a very important family time in our house, and my parents and I get together to eat after a day of work and study, and exchange news and interesting news about the company and society with each other in the interval, and they will also take advantage of this time to care about and ask about my school class.

One day, I heard my mother's voice: "It's time to eat!" I got up from the writing desk and ran to the table in three steps and two steps, and when I looked down, there were braised hairtail, black pepper steak, green beans, borscht and ......Yes!

It's all my favorite dish. As soon as my parents sat down, I couldn't wait to pick up the chopsticks and devour them. I ate the fish on the left and the steak on the right, and my mother smiled and said

Eat slowly, don't choke". Dad looked at me carefully for a while and said, "Xuanxuan, why are you like an African refugee and haven't eaten at noon?"

I said, "There was a dish in the school lunch today that I didn't like to eat, and I only ate one of the eggs and secretly threw out the rest." Dad said angrily when he heard this

It's not good for you to do this, if you want to be healthy, you have to have balanced nutrition, you can't be picky eaters, lunch is the most important meal of the day, if you don't eat enough lunch, you will not concentrate when you go to class in the afternoon, which will affect the effect of listening to the class, and you will waste it by doing so. Hearing this, I couldn't help but slow down the pace of eating and realized my mistake. Mom went on to say:

Girls love beauty, and eating too much dinner will make a lump of fat accumulate on your little belly, arms and thighs, how ugly it will be! "Listening to what my mother said, I really seemed to see a fat little girl in front of me, so ugly! I thought to myself, I must not let myself become like that, so I said to my parents

I know that in the future, I will try to eat the food in school as much as possible, and for those foods that I don't usually like to eat, I will think of them as vitamins A, B, C, D, and E that are good for the body, so that I can eat them." Hearing this, Mom and Dad laughed happily. The story at the dinner table is ...... every day
