Milk was one of the main foods of people long before history was written. It will probably keep on being one as long as there are animals that give milk. Even the word "milk" is very old. It comes from Sanskrit ( ), one of the oldest languages known to man. A very old picture of _ has been found. It was drawn more than five thousand years ago. In the years long ago, people got their milk from their own animals. But later new inventions made the milk industry a big business. In 1851 Gail Borden found a way to take some of the water out of milk. This made it keep much longer. Four years later, Louis Pasteur introduced a way to kill the bacteria ( ) in milk. Next, a special milk bottle was made. This was followed by the invention of machines that could fill bottles with milk. These discoveries had a great effect on the milk industry. They meant that milk could be stored longer. Some people believe that milk drinking will become less popular that it has been. But remember how long milk has been an important food and think of many ways in which it is useful. It seems safe to say that milk industry will always be important. People got their milk mainly from their own animals _ . A) a hundred years ago. B) fifty years ago. C) one hundred and forty years ago. D) before a number of inventions were made.

Do successful businessmen need an office? Increasingly the answer seems to be no. Chris Ward, author of the book Out of Office explains how President Barack Obama's first inauguration speech was written by 27-year-old Jon Favreau sitting in Starbucks ; how Richard Tait, creator of Cranium, started the board game in a coffee shop; how Michael Acton Smith invented the children's virtual world Moshi Monsters in his local cafe Nero; and how JK Rowling, the novelist behind Harry Potter, believes a cafe is the best place to write. It is a convincing view, and for basic start-ups it makes much more sense to work from home and public spaces such as cafes than renting an expensive office. Offices are hard to find, costly to decorate and involve much tiring administration. Moreover, by staying independent you avoid the misery of a daily commute , which for many is the worst part of a job. Thanks to mobile communications, WiFi and cloud storage, together with the increasing heavy-duty equipment such as photocopiers, fax machines and desktop PCs, the traditional office is becoming redundant for many sorts of organizations and workers. Of course, factory managers, surgeons, chefs and industrial chemists are still tied to specialist locations. But many of us---from software engineers and copywriters to architects and fashion designers---can operate almost anywhere. That freedom, and a willingness to adapt, can make one's career more enjoyable and, sometimes, more efficient. What can we infer from the text? A) Many people hate commuting daily. B) The tradition office will no longer exist. C) Working in public places will reduce efficiency. D) Chefs can work anywhere.

Q: If you have ever been sad because of failure,please remember,for often,achieving what you set out to do is not the most important thing. A boy decided to dig a deep hole behind his house.As he was working,a couple of older boys stopped by to watch."What are you doing?" asked one of the visitors."I want to dig a hole all the way through the earth!" the boy answered excitedly.The older boys began to laugh,telling him that digging a hole all the way through the earth was impossible.After a while,the boy picked up a jar.He showed it to the visitors.It was full of spiders,worms and other insects.Then he said quietly and confidently,"Even if I can't dig all the way through the earth,look what I found along the way!" The boy's goal was far too difficult,but it did cause him to dig.And that is what a goal is for--to cause us to move in the direction we have chosen,in other words,to cause us to dig! Not every goal will be fully achieved.Not every job will end successfully.Not every dream will come true.Not every love will last.But when you fall short of your aim,maybe you can say,"Yes,but look what I found along the way!Look at the wonderful things which have come into my life because I tried to do something!" It is in the digging that life is lived.And I believe it is joy in the journey that really matters. The best title for the passage should be _ . A) Joy in the Journey B) A Boy Dug a Hole C) No Pains,No Gains D) Failure Is the Mother of Success

Each Indian tribe had a different language. Many Indians never learned any languages except their own. Do you know how Indians from different tribes talked to each other? They had two ways to talk without sound. One way was by sign language; another way by signals. Sign language is a way of talking by using signs. Indians used sign language when they met strangers. In this way, they could find out whether the stranger was a friend or an enemy. In Indian sign language, signs were made with the hands. One sign meant "man". Another meant "horse". To tell the time of day when something happened, an Indian pointed to the sky. He showed where the sun had been at the time. Indians usually used signals when they wanted to send messages to someone far away. To make signals, an Indian might use a pony. He might use a blanket. Or he might use smoke, a mirror or fire arrows. To signal that he had seen many animals, an Indian rode his pony in a large circle. Sometimes the Indian gave a signal like this and then went away to hide. This meant that there was danger. The blanket signal was visible from far away. An Indian held the corners of a blanket in his hands. Then he began to swing the blanket from side to side in front of him. An Indian could send many different signals with his blanket. He could also send many signals with a mirror. He usually used the mirror to warn someone of danger. Of course, mirrors could be used only when the sun was shining. At night, Indians used fire arrows for signaling. Now you can see that Indians didn't need to learn each other's language. They could talk to one another by using signals or sign language. Blanket signals _ . A) could be seen far away B) could be seen at night C) were used only for warning D) were considered the best way of sending messages
