However, we do know a lot about languages, the languages of today and also the languages of earlier times. There are probably about three thousand languages in the world today. Chinese is the language with the most speakers. English, Russian and Spanish are also spoken by many millions of people. On the other hand, some languages in the world have less than one hundred speakers. There are several important families of languages in the world. For example, most of the languages of Europe are in one large family called Indo-European. The original language of this family was spoken about 4,500 years ago. Many of the present day languages of Europe and India are modern forms of the language of 4,500 years ago. Languages are always changing. The English of today is very different from the English of 500 years ago. In time some even die out completely. About 1,000 years ago English was a little -known relative of German spoken on one of the borders of Europe. If a language has a lot of speakers or if it is very old, there may be differences in the way it is spoken in different areas. That is, the language may have several dialects. Chinese is a good example of dialect differences. Chinese has been spoken for thousands of years by many millions of speakers. The differences between the dialects of Chinese are so great that speakers of Chinese from some parts of China cannot understand speakers from other parts.

Zoo officials say they are concerned about animals.How ever, most zoos remain "collections" of interesting "things" rather than protective habitats .Zoos teach people that it is acceptable to keep animals bored, lonely, and far from their natural bones. Zoos claim to educate people and save endangered species , but visitors leave zoos without having learned anything meaningful about the animals' natural behavior, intelligence, or beauty.Zoos keep animals in small spaces or cages, and most signs only mention the species' name, diet, and natural range .The animals' normal behavior is seldom noticed because zoos don't usually take care of the animals' natural needs. The animals are kept together in small spaces, with no privacy and little opportunity for mental and physical exercise.These results in unusual and self-destructive behavior called zoophobia.A worldwide study of zoos found that zoophobia is common among animals kept in small spaces or cages.Another study showed that elephants spend 22 percent of their time making repeated head movements or biting cage bars, and bears spend 30 percent of their time walking back and forth, a sign of unhappiness and pain. Furthermore, most animals in zoos are not endangered.Captive breeding of endangered big cats, Asian elephants, and other species has not resulted in their being sent back to the wild.Zoos talk a lot about their captive breeding programs because they do not want people to worry about a species dying out.In fact, baby animals also attract a lot of paying customers.Haven't we seen enough competitions to name baby animals? Actually, we will save endangered species only if we save their habitats and put an end to the reasons people kill them.Instead of supporting zoos, we should support groups that work to protect animals' natural habitats. Question: The author tries to persuade readers to accept his argument mainly by _ . Options: A: pointing out the faults in what zoos do B: using evidence he has collected at zoos C: questioning the way animals is protected D: discussing the advantages of natural habitats

(Question)
Read the article and select the best answer. Article: A French wine producer is spreading the wealth with his workers after they discovered nearly $ 1milion worth of gold coins stored in the building's ceiling, according to a French newspaper. "One of the workers was attacking the building's ceiling when gold coins started to rain down on him, followed by sacks of gold, " Francois Lange, the head of a wine company in Les Riceys, France, told the reporter. It's not unusual to hear about treasure hunters searching the ocean for gold and other precious metals lost at sea, but finding $ 1million in your office ceiling is an uneasy thing and a valuable one too, given that demand for gold has reached a new height recently. In 2011, about 31 grams of gold was valued at $ 1,920.30. In all, 497 gold coins were discovered, raining down upon the workers who were busy repairing the building. Made between 1851 and 1928, the coins have a face value marking of $ 20 each. However, together they are now worth nearly $ 1million, according to the newspaper. Lange says he will keep half of the money for himself, and the other half will be shared with the workers who made the discovery. No one knows for sure who placed the coins in the building, but the newspaper reports the building was owned by a wine producer in the 1930s. People haven't known much about these coins for now but don't be surprised if this "buried" treasure story still has another chapter to be told. After all, the $ 1 million of gold coins once belonged to somebody. Just look at the recent legal case being argued between Spain and people who found more than $500 million worth of gold coins in a sunken ship. Question: What can we learn about Francois Lange? Options: A: He is a French wine producer. B: He is a reporter of a newspaper. C: He will have all the valuable coins. D: He is the head of the building workers.
