This tiny organism, invisible under a normal microscope, can wreak havoc on worldwide.There are more viruses on Earth than stars in the universe, so why haven’t we always been maintaining social distance? Primarily because not all viruses can infect us, and for those that do, the body handles them quite well. To put it simply, viruses are extremely small parasites that infect all sorts of life, from the smallest bacteria to the largest mammals; they are considered parasites because they can’t survive by themselves. Viruses infect health y host cells and use their cellular “tools” to make more copies of themselves.Viruses are everywhere—in the air we breathe, the water we drink, and the land on which we walk. Yet, even after being bombarded with viruses, our body still manages to stay strong. This is because of our immune system and its clever strategies to fight back against viral attacks! Fortunately, with our modern healthcare advancements, we have extra help to fight viruses. These include vaccines, antiviral drugs, and other health technologies to keep us going in this never-ending war.As time goes by and our bodies encounter more viruses, we develop better immunological memory. This is the body’s way of remembering past infections, making it better prepared for future ones.8.Which can replace the underlined phrase “wreak havoc on” in paragraph 1?A.Depend heavily on.B.Have a bad effect on.C.Take the side effect off.D.Cut the whole power off.9.Why do we always fail to maintain social distance despite lots of viruses?A.Not all viruses infect humans.B.Not all viruses are small.C.Viruses need host cells.D.Viruses infect all life forms.10.What is one of the strategies our body uses to fight viral attacks?A.Reducing the number of viruses in the environment.B.Avoiding contacting with infected individuals.C.Taking advantage of the immune system.D.Increasing exposure to viruses.11.What can be the best title for the text?A.What is the definition of unusual viruses?B.How to know well the immune system?C.How does our body fight viruses?D.How to break down the viruses?A major tech company has expanded options for keeping personal information from online searches. The company stated earlier this week that it would allow people to request the removal of more types of content, such as personal contact information like phone numbers, email addresses, and physical addresses, from search results. The new policy also permits the removal of other information that may pose a risk for identity theft, such as confidential (机密的) login accounts.In a statement, the company said that open access to information is vital. “But so is empowering (授权) people with the tools they need to protect themselves and keep their sensitive, personally identifiable information private,” the statement continued. “Privacy and online safety go hand in hand. And when you’re using the Internet, it’s important to have control over how your sensitive, personally identifiable information can be found.”Previously, the company had allowed people to request the removal of highly personalcontent that could cause direct harm. This included information such as bank account or credit card numbers that could be used for fraud (欺诈).“However, as information increasingly appears in unexpected places and is used in new ways, policies need to evolve,” the company said. Having personal contact information openly available online can also pose a threat, and the company reported receiving requests to remove such content as well. It states that when it receives such requests, it will review all the content on the web page to avoid limiting the availability of useful information or content on public record on government or other official websites. “It’s important to remember that removing content from our search results won’t remove it from the Internet, which is why you may wish to contact the hosting site directly, if you’re comfortable doing so,” the company advised.12.What can we learn from the company’s statement?A.Keeping online private information safe is a must.B.Improving the net environment for citizens is a dream.C.The exposure of public information causes a discussion.D.Making a balanced approach to online safety is a fashion.13.Why does the company review web page content before removing personal information?A.To obey data privacy laws.B.To take down the entire website.C.To increase online personal information.D.To avoid removing useful or publicinformation.14.What is the main idea of the text?A.Personal information can be removed from online searches.B.Tech companies can find more images and information.C.Privacy risks arise from publishing private information.D.Tech companies know what you’ve done over the years.15.What is the text likely to be?A.A research paper on online privacy.B.A new approach to using a search engine.C.An advertisement for a data privacy service.D.A news report about privacy protection.Do you know what carpet cleaning is and how it works?

活着的英语流行语Living English Idioms。

Idioms are a fascinating aspect of language that add color and depth to our conversations. They are expressions that have a figurative meaning, different from the literal meaning of the words used. In this article, we will explore some commonly used English idioms that are still very much alive in today's language.1. "Break a leg"This idiom is often used to wish someone good luck, especially before a performance or an important event. It originated in the theater, where actors would wish each other the opposite of good luck, as a way to ward off bad luck. It is believed that saying "break a leg" brings good fortune instead.2. "Bite the bullet"When someone is faced with a difficult or unpleasant situation and decides to face it bravely, we say they are "biting the bullet." This expression originated from the practice of giving soldiers a bullet to bite on during surgery to help them endure the pain without making noise.3. "Cost an arm and a leg"If something is very expensive, we can say it "costs an arm and a leg." This idiom emphasizes the high price of something, even though it is not to be taken literally. It is often used to describe extravagant purchases or overpriced items.4. "Hit the nail on the head"When someone accurately identifies or solves a problem, we say they have "hit the nail on the head." This idiom comes from the act of hitting a nail directly on its head, resulting in a successful outcome. It is often used to praise someone's precise understanding or solution.5. "Piece of cake"If something is very easy or simple to do, we can describe it as a "piece of cake." This idiom refers to the ease of cutting and eating a piece of cake, implying that the task at hand requires minimal effort. It is commonly used to express confidence or dismiss a challenge.6. "Break the ice"When we want to initiate a conversation or make a situation more comfortable, we "break the ice." This idiom comes from the idea of breaking the ice that forms on a body of water, symbolizing the initial barrier between people. It is often used in social situations or when meeting someone for the first time.7. "Spill the beans"To reveal a secret or disclose confidential information unintentionally, we say someone has "spilled the beans." The origin of this idiom is unclear, but it is commonly used to describe someone accidentally sharing information that was meant to be kept secret.8. "Kick the bucket"When someone passes away or dies, we say they have "kicked the bucket." This idiom is a euphemism for death and is believed to have originated from the act of a person standing on a bucket with a noose around their neck, kicking the bucket away to commit suicide.9. "The ball is in your court"When it is someone's turn to take action or make a decision, we say "the ball is in your court." This idiom comes from sports, particularly tennis, where the ball is hit back and forth between players. It is often used to prompt someone to take responsibility or make a choice.10. "Hold your horses"If someone is being impatient or rushing into something, we tell them to "hold their horses." This idiom refers to the need to control one's excitement or impatience, just like holding onto the reins of a horse to prevent it from running off. It is often used to advise someone to be patient or wait.In conclusion, idioms are an integral part of the English language, enriching our conversations with vivid imagery and cultural references. These ten idioms are just a glimpse into the vast array of expressions that are still very much alive in everyday English. By understanding and using idioms appropriately, we can enhance our language skills and better connect with native speakers. So, go ahead and break a leg in incorporating these idioms into your English conversations!。

难道这就是生活吗英语作文

难道这就是生活吗英语作文

难道这就是生活吗英语作文Is this what life is all about? Waking up every morning to the same routine, the same responsibilities, the same struggles. It feels like a never-ending cycle of monotony and predictability.Sometimes I wonder if this is really all there is to life. Working hard, paying bills, dealing with stress and anxiety. Is this really what I signed up for when I entered the adult world?But then there are moments that make me think otherwise. The laughter of friends, the warmth of family, the beautyof nature. These are the moments that remind me that lifeis more than just a series of tasks and obligations.I guess life is a mix of both the mundane and the extraordinary. It's about finding joy in the little things while navigating through the challenges that come our way.It's about creating our own meaning and purpose in a worldthat can sometimes feel overwhelming and chaotic.So maybe this is what life is all about the ups and downs, the twists and turns, the moments of despair and the moments of pure bliss. It's messy and unpredictable, butit's also full of opportunities for growth and self-discovery.In the end, maybe life is what we make of it. It's about finding our own path, pursuing our passions, and learning to appreciate the journey, no matter how bumpy it may be. Maybe, just maybe, this is what life is all about.。

急救与生活英语作文

急救与生活英语作文

急救与生活英语作文The Intersection of First Aid and Daily Life.Life is unpredictable, and emergencies can strike at any moment, without warning. It is crucial to be prepared with the knowledge and skills necessary to respond effectively in such situations. First aid is not just a set of techniques to be learned in a classroom or a course; it is an essential life skill that can make a significant difference in someone's life, perhaps even saving it. The integration of first aid principles into our daily lives is vital, as it empowers us to act confidently and competently in the face of danger.The foundation of first aid is built on the concept of ABC – Airway, Breathing, and Circulation. These three elements form the cornerstone of any emergency response. Ensuring a victim's airway is clear, maintaining their breathing, and promoting blood circulation are paramount in stabilizing a situation and preventing further harm. In ourdaily lives, we can apply these principles by beingvigilant of our surroundings and prepared to assist in case of an accident.For example, when driving, we should always keep an eye out for pedestrians and cyclists, ready to react quickly if necessary. In the event of a collision, knowledge of first aid can guide us in assessing the situation and providing immediate assistance. Similarly, in our homes, we should be aware of potential hazards such as slips, falls, and fire accidents. By having a basic first aid kit handy and knowing how to use it effectively, we can minimize the risk of injury and potentially save lives.Moreover, first aid skills are not limited to physical injuries. Mental health emergencies are equally important and often require a different approach. Listening attentively, offering reassurance, and guiding individuals towards professional help can be as crucial as applying a bandage to a wound. In our social interactions, we can apply these skills by being empathetic and supportive towards those who may be experiencing stress or distress.The integration of first aid into our daily lives also involves promoting a culture of safety and preparedness. This can be achieved through education and awareness. By sharing knowledge and skills with family, friends, and community members, we can create a safer environment where everyone is equipped to handle emergencies. Additionally, organizations and institutions can play a crucial role by providing regular first aid training and making it a part of their emergency response plans.In conclusion, the integration of first aid into our daily lives is not only a practical necessity but also an expression of our humanity. It is about being prepared, being responsible, and being compassionate towards others. By embedding first aid principles and skills into our daily routines, we can create a safer, more resilient society where everyone has the ability to make a difference in an emergency. Let us make the commitment to learn, practice, and share first aid, so that we may all be agents of change in promoting health and safety in our communities.。

Title mutated from Tom Ray's \ancestor". 1
for all cells in the lattice. Because of this the c.a. are in information theory called sliding block codes; one moves e.g. a rule template like in Figure 1a over the integers (the upper rule computes the value in the grey cell based on two neighboring cells above, the lower according to the cell and its three nearest neighbors on both sides). If the local rule is instead de ned on a two-dimensional neighborhood we will get a two-dimensional c.a.
1. What are they?
Cellular automata ( ) c.a. in their purest form are deterministic rules for describing the evolution of an array of objects. Consider the simplest set-up of a cellular automata de ned on the one-dimensional integer lattice. Let each cell (integer site) be in one of two possible states, 0 = dead and 1 = alive. The c.a. rule is the recipe how the cells are updated based on their own and neighbor's states. The same local rule is applied everywhere and the update is synchronous i.e. done simultaneously
Figure 1b. shows a 16 step evolution of a simple c.a. The rule is 1 0 7! 1, 0 1 7! 1 whereas the other four triples map to 0 ( is the wild card). Zeros are rendered white and ones as black squares and time runs downwards. The rule is simple since it is a linear c.a. i.e. allows superposition of con gurations. Yet surprisingly it shows some promise in our quest for alife: by examining the con gurations (the horizontal strings of 0's and 1's) one notes that the nal con guration (bottom) consists of two exact copies of the initial con guration (top). So the initial con guration has self-reproduced under the c.a. rule! One should note that this is not the property of the chosen string i.e. same would hold for any string of the same length.
The phenomenon at hand is relaxation, evolution towards the ground state of the system where the colors form large contiguous blocks. Another way of describing this process is by considering the boundaries between domains of di erent colors. These \particles" seem to move in a random fashion and depending on how their types match, upon collision they annihilate or coalesce ( 3]). The process is irreversible and indeed this is a prime example of non-equilibrium statistical mechanics. Note that the phenomenon is in a way also self-organization as the system transforms the completely random initial \symbol soup" into something more structured. But the problem is that the complexity of the limit is low i.e. the rule doesn't create patterns with intricate structure so characteristic of life. By complexity we simply (!) mean the length of the minimal description of the object.

Is it alive or is it a cellular automaton?

eloranta@janues cannot be synthesized my man." (Vitalists)
Introduction
Ever since the fundamental contribution by von Neumann cellular automata have enjoyed a central position in the development of ideas of arti cial life ( 7]). They are at the crossing point where physical phenomena described by statistical mechanics and information theoretic concepts of computation meet with often surprising results. In this article we will make a brief excursion to this territory.
2
2. What are they capable of?
In simulations (e.g. 8]) c.a. exhibit a staggering variety of phenomena. Instead of trying describe it all and classify c.a. we will here discuss those types of behavior that seem to have bearing to self-organization and evolutionary phenomena. Figure 2a. it is not a snapshot of stalactites in an ice cave but it does in a very physical sense model a system freezing towards a ground state. It represents a hundred step evolution of a c.a. with a rule of the type in Figure 1a top. There are six states, which are rendered white, grey and black, each with two shades. The initial state is completely disordered i.e. the \color" and shade of each cell is independent of the other.
The key ingredients in the de nition are the locality of interaction of the cells and the fact that the rule, the \physical law" is everywhere the same. Variations exist, e.g. one can add noise to the updating process to get a probabilistic c.a. or do asynchronous updates. These are interesting and important but we'll omit them here.
