Q: Article: Howling is a behavior commonly observed among a wolf nark. An animals, wolves work together to hunt and rely on howling was an important means of communication each other. There are different explants of a wolf's howl and it appears that there may be more to discover.      One theory is that wolves howl to bend better together. It's almost as if howling together helps the pack stay together. Perhaps something similar to people feeling a sense of involvement with each other when singing a song together . But this theory may be wrong, explains Fred H. Harington, a professor who studies wolf behavior.     Indeed, there have been tines when wolves have been seen one moment howling in a exhorts, and the next, quarreling anions each other. It appears that usually the lowest-tanking menthes of the pack may actually be "punished" for Joining in the churs at times. So is howling a way to strcagthen a social boad or just a way to reconfirm status among its members? ----Why do welves howl for sure? What is cleat, however, is that howling is often used among packmates to locate each other. Hunting grounds are distant and it happens that woloves may separate from one another at times. When this happens, howling appcars to be an ercellent means of gathering. Howling, interestingly, is a contagious behaviour. When one wolf starts to howl, very likely others will follow.

Q: Article: The English language is the result of the invasion  of the island of Britain over many hundreds of years.The first invasions were by a people called Angles about 1, 500 years ago. The Angles were a German tribe who crossed the English Channel . Later two more groups crossed to Britain. They were the Saxons and the Jutes. Through many years, the Saxons, Angles and the Jutes mixed their different languages. The result is what is called Anglo-Saxon or old English. The next great invasion of Britain was done by Vikings about 1, 100 years ago. Many English words used today come from these ancient Vikings. The next invasion of Britain took place more than 900 years ago, in 1066. History experts call this invasion the Norman Conquest. The Normans were a French-speaking people from Normandy in the north of France. These new rulers  spoke only French for several hundred years. It was the most important language in the world at that time. It was the language of educated people. But the common people of Britain still spoke old English. Old English took many words from the Norman French. Some of these include "damage", "prison", and "marriage". The French language used by the Norman rulers greatly changed the way English was spoken 800 years ago. English became what language experts call Middle English. Middle English sounds like Modern English. But it is difficult to understand now. The history of the English language continues as Middle English becomes Modern English, which is spoken today.
