Model essay on life speech 1

Dear teachers and students:

Hello everyone!

With the announcement of the results of the college entrance examination, our seniors and sisters will begin to fill in their volunteers, fill in their volunteers for the university they want to go to, and pave the way for their yearning life. As a senior two student, before I enter senior three, I still want to talk about "the life I yearn for" and the direction I will work hard in senior three.

I used to be a person who didn't like studying very much. Now I love studying, because I have a life I yearn for. I yearn for a university that can make me more free, and I yearn to know more souls who think independently. I am eager to go to my favorite city and start my real life in that city without my parents' concern; I look forward to staying in my favorite city after graduating from college, looking forward to taking root there, and then bringing my parents together. These are all indispensable parts of my yearning life, and they are also the reasons why I love learning completely.

Because I know that whoever wants to live the life he yearns for must work hard, and as a student at school, learning is our struggle. Only by studying can we fly to the life we yearn for, say hello to the life we yearn for, and then live in it and continue to create a better life.

Students, have you ever thought about what your life is like? If you thought about it, you must be very angry now! If you haven't thought about it yet, think about it quickly and give yourself a direction to move forward! As students who are about to enter senior three, our awakening at this time is very important. This is so important that we can even write about our future.

If life is a mirror, then I can always see what we really look like in life. If you have the life you want, you have to work hard. Only when you stand in front of the life you want, will you accept that life, otherwise you will always find that your life seems to be a failure, your life seems to be not beautiful, and you don't seem to know where the direction is.

Students, when you have the life you want and the life you yearn for, you won't worry about the immediate things. You will always forget the small troubles in front of you because of your long-term planning, and then become an atmospheric person, a person who can live the life you yearn for with his own actions!

One year, it is only one year or even less before we fill in our volunteers like seniors and sisters at this time. Only when things are clear can we start better. We all want to live the life we want. Think about it!

Thank you!

Dear students:

Good afternoon, everyone. I am very happy to be here with you to discuss the speech on network security. The topic of my speech today is: Internet, a wonderful and dangerous world.

Network world, a wonderful world. But there is danger behind the wonderful. Have you ever thought that the theft of your qq number may be caused by a virus, your system may be hijacked, and it may be the fault of hooligans; Your online bank was stolen, probably a phishing website. Your data is missing, don't say, it's probably a hacker. Everyone has always had a "special feeling" for hackers, thinking that all hackers are very powerful, otherwise how can they create viruses in computers.

Since there are hackers, there must be security personnel. What kind of "confrontation" is going on behind this online world? So today I will take you into the security field of this online world as a security officer.

My speech is divided into five parts: what is network security, the importance of network security, the current situation of network security, how to prevent network security and build a harmonious network.

First, let's take a look at what we mean by "network security". Network security refers to protecting the hardware, software and data in the network system from being destroyed, changed or leaked by accidents or malicious reasons, and the system runs continuously, reliably and normally without interrupting network services.

The specific meaning of network security is users (individuals, enterprises, etc. It is hoped that information involving personal privacy or business interests will be protected by confidentiality, integrity and authenticity when transmitted on the network.

At the same time, network security is a comprehensive subject involving computer science, network technology, communication technology, cryptography technology, information security technology, applied mathematics, number theory, information theory and other disciplines.

Alvin toffler Toller, an American futurist, once said, "Whoever can get information and control the Internet will own the whole world." In the past, President Clinton of the United States also said, "The country that will control the world in the future will not rely on the army, but the country with leading information capabilities." This shows how important it is to master the network, and the importance of network security is also reflected.

Here are some fbi data: According to fbi statistics, the economic losses caused by cyber security problems in the United States are as high as $7.5 billion every year. On the other hand, there is an average network computer intrusion every 20 seconds in the world.

In a large number of applications of internet/intranet, the security of internet/intranet is facing great challenges. In fact, resource sharing and security have always been a contradiction. In the open network environment, a large amount of information flows online, which provides the target for criminals to attack. Moreover, the diversity of computer network components, the wide distribution of terminals and the openness and interconnection of the network provide more convenience for it.

They use different means of attack to access or modify sensitive information flowing in the network, break into the computer system of users or government departments, peep, steal and tamper with data. Internet fraud, which is not limited by time, place and conditions, has stimulated the growth of crime to some extent because of its "low cost and high income". Criminal activities against computer information systems are increasing.

Let's take a look at the content of the third section "Network Security Status", which is also the problem that our network is facing now.

1, the problem of network security integrity is serious.

With the development of the Internet, especially the rapid development of commercial applications, many lawless elements have extended their black hands to the Internet, resulting in frequent threats to network security and credit crisis in recent years. According to the white paper "Internet Status in China", in 20__ years, the ip addresses of computers controlled inside and outside China reached 1 10,000; There are 42,000 websites tampered with by hackers; The number of computers infected with "phreak" worm network virus reaches180,000 every month, accounting for about 30% of the number of infected hosts in the world. According to the information provided by the Ministry of Public Security, in the past five years, the number of viruses spread on the Internet in China has increased by more than 80% annually. Eight out of every 10 computers on the Internet are controlled by hackers, and the cases related to hacker attacks and sabotage activities accepted by public security organs have increased by 1 10% annually. Therefore, the network

The construction of network security environment has become an obstacle to the development of the Internet.

2. Weak awareness of information protection

Safety awareness needs to be improved urgently. This requires netizens to learn more about the network and enhance their awareness of self-protection of personal information online.

3. The development of information network security service industry is not mature enough.

I won't explain this much, mainly related to the network security department.

Regarding network security, it can be said that malicious codes are rampant and the number of viruses is exploding. Please look at ppt, which is the data of Kabbah Laboratory in recent 20 years (1992-20__). According to the data, more than 30 million new malware were discovered in 20__ and 20__ years alone. It shows that the network security situation is extremely severe.

Network security is a problem, of course, it must be solved, so how to prevent it? First of all, there will be no pie in the sky, don't be greedy and cheap, and don't be confused by some "winning traps". However, if you disclose a lot of personal information, the password setting should not be too simple. Don't use your birthday as a password, because it is not safe. As we all know, I won't say much about this. There are also many softwares downloaded to regular websites to avoid downloading files that bind Trojans. Don't be fooled by "fishing nets" in online shopping. Install anti-virus software and firewall on the computer, update security vulnerabilities in time, and avoid hacking.

Well, that's all for me. I wish everyone a safe and harmonious online life. Thank you for watching! ! !

Dear teachers and students:

Hello everyone!

I saw the propaganda about "low-carbon life" from many places and felt its importance.

"Low-carbon life" can be achieved in many ways, such as saving water and electricity and planting trees. Our family has achieved a "low carbon life" in many details. Please listen to my detailed introduction below.

Take saving water as an example. The water used for washing clothes, washing face and bathing in our house is accumulated in a large washbasin, and you can use it if you want to flush the toilet. Perhaps, you are familiar with saving rice washing water and washing water, but you don't know much about how to save bath water. When I take a bath, I put two washbasins in front and one washbasin in the back. The first two are smaller and the last one is bigger. In this way, excess water can enter the washbasin to achieve the purpose of accumulating water. In addition, the faucet in our house is usually not too big, which is conducive to controlling the flow of water. These are the stories of saving water in our family.

Next, let's tell a story about saving electricity. After each bath, we will unplug the water heater to avoid empty burning of the water heater; Every time after cooking, we will unplug the power supply of the rice cooker so that it will no longer use electricity; Every spring or autumn, we will unplug the air conditioner to prevent it from "eating electricity" for half a year, which can save a lot of electricity.

Every spring, I go to my grandmother's house and plant some small trees in the field with them. Sometimes grandpa will buy some flowerpots and seeds for us to plant. After I got these flower seeds, my sister and I immediately went to the field to find some soil and put it in flowerpots for adults to teach us to grow flowers. This is both low-carbon and ornamental. It's killing two birds with one stone.

As the saying goes, "If you share your happiness with your friends, it will become two happiness." Here, I hope to share my experience of "low-carbon life" with you, and hope that our living environment will become more and more low-carbon, more environmentally friendly and healthier.

Before I came there to go to college, I always imagined that my college life was perfect. Then a senior told me not to imagine college life too beautiful. I didn't realize it until I went to school. Although someone told me about college before, I was still a little disappointed. I believe many people talk to me about their ideas. The reason why many people don't adapt to college life is largely misled by some novels about college life on the internet or in magazines. Many authors describe university life in a mocking tone and describe an ideal university for readers. Misguided by this, everyone will have an ideal description of their college life before entering the university. With this perfection, many people will be confused for a period of time after entering the university, and fully enjoy the sudden freedom and novelty. However, after class and self-study day by day, this passion gradually faded and began to enter a confused stage, missing high school classmates and high school life.

There are a lot fewer classes this semester, and every day is very free. Sometimes I sleep in the dormitory. Even if I sleep for a day. I like reading books and go to the library in my spare time. Then cut

When I am free, I will think about something. Talk about the future with your classmates. And then found that we were still confused about the future. Although I was confused in high school, I had at least one goal. At that time, the only goal was the college entrance examination. I'm even more confused when I get to college. I always think that college life should be rich and colorful. But the reality is not entirely so. But overall, it's good. My classmates always ask me how to go to college so far away. Then I will tell them that maybe I can go to school anywhere, but I want to go to different places and see different cultures and customs. In fact, these are all a kind of learning. They don't agree with my idea. But these can only be understood by yourself. I think these are the biggest gains from coming there. I learned a lot there.

In the past, I always liked to daydream with my chin cupped. In my dream, I was so happy and smiled so brightly! Live all kinds of lives you want, and don't want to wake up for a long time. At this moment, I will still dream, but I will always wake up soon, and then I will find the existence of reality, breathe out a sigh gently and start a new life. College is the perfect time to fall in love in my life, but I have no desire and pursuit for feelings. I like being bored with my good friends every day. We fantasize about our future, share our stories and dream all kinds of dreams together!

Many people ask me what I think of college life, and I will smile. I don't think I can find specific words and sentences to describe him. It is still my dream place. I will cherish every day and spend this different dream with my dearest friend, my university.
