The weather is a national obsession in Britain, perhaps because it is so changeable. It's the national talking point, and most people watch at least one daily weather forecast. Most of the viewers imagine that the presenter does little more than arrive at the studio a few minutes before the broadcast, read the weather, and then go home.
In fact, this image is far from the truth. The two-minute bulletin which we all rely on when we need to know tomorrow's weather is the result of a hard day's work by the presenter, who is actually a highly-qualified meteorologist.
Every morning, after a weather forecaster arrives at the TV studios, his/her first task of the day is to collect the latest data from the National Meteorological Office. The information is very detailed and includes predictions, satellite and radar pictures, as well as more technical data. After gathering all the relevant material from this office, the forecaster has to translate the scientific terminology and maps into images and words which viewers can easily understand. The final broadcast is then carefully planned. The presenter decides what to say and in what order to say it. Next a “story board” is drawn up which lays out the script word for word.
The time allocated for each broadcast can also alter. This is because the weather report is screened after the news, which can vary in length. The weather forecaster doesn't always know how much time is available, which means that he/she has to be thoroughly prepared so that the material can be adapted to the time available.
What makes weather forecasting more complicated is that it has to be a live broadcast and cannot be pre-recorded. Live shows are very nerve-racking for the presenter because almost anything can go wrong. Perhaps the most worrying aspect for every weather forecaster is getting the following day's predictions wrong. Unfortunately for them, this is not an unusual occurrence; the weather is not always possible to predict accurately.
These days, a weather forecaster's job is even more complicated because they are relied upon to predict other environmental conditions. For example, in the summer the weather forecast has to include the pollen count for hay fever sufferers. Some also include reports on ultraviolet radiation intensity to help people avoid sunburn. The job of a weather forecaster is certainly far more sophisticated than just pointing at a map and describing weather conditions. It's a job for professionals who can cope with stressful and challenging conditions.

Rachel Carson was born in 1907 in Springdale, Pennsylvania. She studied biology in college and zoology at Johns Hopkins University, where she received her master's degree in 1933. In 1936, she was hired by the US Fish and wildlife service, where she worked most of her life. Carson's first book, Under the Sea Wind, was published in 1941. It received excellent reviews, but sales were poor until it was reissued in 1952. In that year, she published The Sea Around Us, which provided a fascinating look beneath the ocean's surface, emphasizing human history as well as geology and marine biology. Her language had a poetic quality. Carson consulted no less than 1,000 printed sources. She had voluminous correspondence and frequent discussions with experts in the field. However, she always realized the limitations of her non-technical readers. In 1962, Carson published Silence Spring, a book that sparked considerable controversy. It proved how much harm was done by the uncontrolled, reckless use of insecticides. She detailed how they poison the food supply of animals, kill birds, and contaminate human food. At that time, spokes men for the chemical industry mounted personal attacks against Carson and issued propaganda to indicate that her findings were flawed. However, her work was vindicated by a 1963 report of the President's Science Advisory Committee.

A pilot cannot fly by sight alone. In many conditions, such as flying at night and landing in dense fog, a pilot must use radar, an alternative way of navigating. Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving. The basic principle of radar is exemplified by what happens when one shouts in a cave. The echo of the sounds against the walls helps a person determine the size of the cave. With radar, however, the waves are radio waves instead of sound waves. Radio waves travel at the speed of light, about 300,000 kilometres in one second. A radar set sends out a short burst of radio waves. Then it receives the echoes produced when the waves bounce off objects. By determining the tune it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects. The word "radar" in fact gets its name from the term "radio detection and ranging". "Ranging" is the term for detection of the distance between an object and the radar set. Besides being of critical importance to pilots radar is essential for air traffic control tracking ships at sea, and for tracking weather Systems and storms

There is no conflict between big business and the green movement towards the fight  against climate change and the two are “totally compatible”. That’s according to Mike Hughes, Zone President, Schneider Electric UK & Ireland, who believes while there may be differences on how organisations play their part in the move towards the net zero target and the speed at which it happens, the two are “totally aligned”.  Speaking to ELN at the Energy Live Expo event last week, which attracted more than 450 people from across the industry, he said: “Big business goes where there is opportunity. Big business is a force for good. It has to be involved in this transition, in this change, in this climate change. If you look at it, there are two things that have happened in the last five to seven years that have really accelerated this topic. One is the general public getting on board with the whole concept of climate change, the emergency. The second is actually the business community and particularly the financial community starting to look at the financial risks around climate change and moving its money and where it will invest.”  Mr Hughes added the UK’s target for net zero carbon emissions by 2050 is a “hugely ambitious step” and it shows leadership, direction and ambition, enabling businesses to focus on where they can invest. He is also “extremely optimistic” and from a technology point of view, he believes there are technologies available to support the transition. He said: “It’s now around awareness, incentives from government, the right regulations to get people to make the right step and boosting the use of these technologies. I’m extremely positive.”

According to the report, we can expect some pretty remarkable changes to our homes  and our personal spaces, overlooked things that make up so much of our daily routine. As human populations soar, our cities and homes will have to adapt; interior living spaces will change as a cloud changes, easily reconfigured and rearranged to suit our fickle tastes, or accommodate different purposes.  Imagine walls and floors made of a malleable “skin,” and embedded with tiny sensors and actuators so that the shape and size of living spaces can quickly change, or even be divided into smaller rooms; imagine fully programmable “smart homes” that can be controlled remotely, and provide feedback to their owners - yes, there’ll even be an app for that.  Virtual decorations will alter with changing tastes, moods and whims; and the entire interior surface of the home will be implanted with LED technology - television screens and computer displays will form and unform in any room, as needed. Even our furniture will be adaptable, molding to custom fit our bodies, responding to changes in posture, or disappearing altogether when not needed.  It will be the ultimate evolution of the “Internet of Things.” Misplaced something? Can’t find your keys? No problem. Just use an online search function to find it. Hate the color of that accent wall? Delete it. Need more storage space? Watch new shelves appear, as if by magic. And the amenities are fantastic. Every home will come standard with a 3D printer; they’ll be able to churn out just about anything you could wish, using downloadable patterns, probably including even complex electronic devices. They may even print out your meals, designed and programmed by the world’s master chefs.  Walk-in “medical pods,” meanwhile, will contribute to the decentralization of healthcare - their imaging sensors will diagnose your ills and, for the more easily treatable maladies, dispense drugs, inject antibiotics, and recommend health regimens. It may even be possible to undergo remote, robot-mediated surgery, in the comfort of your own home.  This barely scratches the surface. Imagine homes whose very building material is salted with dormant limestone-producing bacteria, which awaken upon contact with moisture and repair any cracks or structural damage.  There will be “digestion tanks” full of anaerobic bacteria, to dispose of our waste; and our homes will produce, store, and reuse their own energy, using “microbial fuel cell stacks” and more efficient solar panels to generate electricity, and power-banks like the Tesla power wall to store it against future use. Personal homes will be almost fully independent of a dangerously overtaxed energy grid.  One hundred years in the future, our houses will be, in almost all respects, semiliving, artificial organisms - closed systems with a metabolism, sensory apparatus, immune response, and an approximation to a nervous system. We’ll be living in homes that are practically alive.

Altruism is a type of behavior in which an animal sacrifices its own interest for that of another animal or group of animals. Altruism is the opposite of selfishness; individuals performing altruistic acts gain nothing for themselves. Examples of altruism abound, both among humans and among other mammals. Unselfish acts among humans range from the sharing of food with strangers to the donation of body organs to family members, and even to strangers. Such acts are altruistic in that they benefit another, yet provide little reward to the one performing the act. In fact, many species of animals appear willing to sacrifice food, or even their life, to assist other members of their group. The meerkat, which is a mammal that dwells in burrows in grassland areas of Africa, is often cited as an example. In groups of meerkats, an individual acts as a sentinel, standing guard and looking out for predators while the others hunt for food or eat food they have obtained. If the sentinel meerkat gains nothing – it goes without food while the others eat, and it places itself in grave danger. After it issues an alarm, it has to flee alone, which might make it more at risk to a predator, since animals in groups are often able to work together to fend off a predator. So, the altruistic sentinel behavior helps ensure the survival of other members of the meerkat’s groups.

Dr. Daniel Quon has been an oral surgeon in Jackson for over 30 years. “Growing up  in the family business, I knew that in order for you to gain something, you have to give back,” Quon said. “And being in the field of dentistry, we have a special gift that we can help people and I thought that was an appropriate way to help out.”  Quon volunteers his dental services at the Jackson Free Health Clinic to patients who can’t afford it. Through the Mississippi Dental Association, Quon also provides free dental care for the Mission Service of Mercy program. Dental Assistant Carley Welch has been a part of this experience. “We actually did that last year together and we plan on doing that again this year together,” he said. “Best boss you can ask for,” Welch continued. “Very patient, always willing to teach you; even things that most people wouldn’t go very far to teach you, he will. Just so you have the experience.” But Quon serves in other ways too. “Wife and I volunteer at the Stewpot. We serve lunch on Saturdays when we can. I was actually on the board of Stewpot for 3 years until this passed year.” And he donates blood platelet at the Mississippi Blood services. “I’m almost up to 18 gallons right now in donations. That’s a lot of blood! still got a little bit left though.” “It takes very little time to volunteer. It’s a great thing where you can help someone who needs an extra hand or helping hand.” “I think he does his part to contribute as much as possible,” Welch added. “Whether it’s helping dental wise or even just in general with the public.”

The human criterionfor perfect vision is 20/20 for reading the standard lines on a Snellen eye chart without a hitch. The score is determined by how well you read lines of letters of different sizes from 20 feet away. But being able to read the bottom line on the eye chart does not approximate perfection as far as other species are concerned. Most birds would consider us very visually handicapped. The hawk, for instance, has such sharp eyes that can spot a dime on the sidewalk while perched on top of the Empire State Building. It can make fine visual distinctions because it is blessed with one million cones per square millimetre in its retina. And in water, humans are farsighted, while the kingfisher, swooping down to spear fish, can see well both in the air and water because it is endowed with two foveae – areas of the eyes, consisting mostly of cones that provide visual distinctions. One foveae permits the bird, while in the air, to scan the water below with one eye at a time. This is called monocular vision. Once it hits the water, the other foveae joins in, allowing the kingfisher to focus both eyes, like binoculars, on its prey at the same time. A frog’s vision is distinguished by its ability to perceive things as a constant moving picture. Known as “bug detectors”, a highly developed set of cells in a frog’s eyes responds mainly to moving objects. So, it is said that a frog sitting in a field of dead bugs wouldn’t see them as food and would starve.
The bee has a “compound” eye, which is used for navigation. It has 15,000 facets that divide what it sees into a pattern of dots, or mosaic. With this kind of vision, the bee sees the sun only as a single dot, a constant point of reference. Thus, the eye is a superb navigational instrument that constantly measures the angle of its line of flight in relation to the sun. A bee’s eye also gauges flight speed. And if that is not enough to leave our 20/20 “perfect vision” paling into insignificance, the bee is capable of seeing something we can’t – ultraviolet light. Thus, what humans consider to be “perfect vision” is in fact rather limited when we look at other species. However, there is still much to be said for the human eye. Of all mammals, only humans and some primates can enjoy pleasures of colour vision.

According to the passage, why might birds and animals consider humans very visually handicapped?

Communication in general is process of sending and receiving messages that enables humans to share knowledge, attitudes, and skills. Although we usually identify communication with speech, communication is composed of two dimensions - verbal and nonverbal.

Nonverbal communication has been defined as communication without words. It includes apparent behaviors such as facial expressions, eyes, touching, tone of voice, as well as less obvious messages such as dress, posture and spatial distance between two or more people.

Activity or inactivity, words or silence all have message value: they influence others and these others, in turn, respond to these communications and thus they are communicating.

Commonly, nonverbal communication is learned shortly after birth and practiced and refined throughout a person's lifetime. Children first learn nonverbal expressions by watching and imitating, much as they learn verbal skills.

Young children know far more than they can verbalize and are generally more adept at reading nonverbal cues than adults are because of their limited verbal skills and their recent reliance on the nonverbal to communicate. As children develop verbal skills, nonverbal channels of communication do not cease to exist although become entwined in the total communication process.

Thirty years after ghostwriting Donald Trump’s The Art of the Deal, Tony Schwartz described the experience as like putting lipstick on a pig. He felt a “deep sense of remorse” at helping bring the man who would become president gain wider attention. This week, the writer Natalie Beach joined the grand tradition of ghostwriters speaking out about their subjects, with a deeply intimate essay in the Cut laying out how she used to ghost everything for her former friend and controversial “influencer” Caroline Calloway: from Instagram captions to the aborted book that once attracted a $375,000 (£300,000) publishing deal, until their relationship broke down irretrievably. Beach’s account says that after the pair put the book proposal together, the influencer felt unable to write it. Beach says she “bought us time with the publishers by writing a quarter of the manuscript by myself”. As a ghostwriter himself, Crofts questions the ethics of speaking out about his subjects’ lives. “I do think Tony Schwartz shouldn’t have come out and said anything about Trump, because you’ve taken the money. It’s like a lawyer: if you find that the person you’re representing is a murderer you can’t then go around bewailing the fact you defended them – that was your job,” he said. “But I think he made Trump, I don’t think Trump would be president if he hadn’t written that book for him, because he’d never have got The Apprentice without the book, and the presidency without The Apprentice. So it must be weighing heavily on his conscience.”  Ghostwriters must be good at several things – being amenable to being steered by a subject, while also being firm enough to guide them away from tangents and uninteresting details. But the most important thing in ghostwriting, says Crofts, is absence of ego. “Which is maybe what went wrong [with Calloway] – Natalie isn’t a born ghost, she’s a writer herself. She was really young and well out of her depth, completely swamped by this girl’s flamboyance,” he says. “Ghostwriters do attract a lot of fantasists and people who have ideas way above the likelihood of success. They always think their story is fantastically interesting and going to be a bestseller. You’re always dealing with people with larger-than-life egos, so there’s always a danger you’re going to run up against someone who is impossible to manage.”
