Other things can also carry messages. For example, a sign at the bus stop helps you to know which bus to take. A sign on the wall of your school helps you to find the library. Signs on doors tell you where to go in or out. Have you ever noticed that there are a lot of signs around you and that you receive messages from them all the time?People can communicate in many other ways. An artist can use his drawings to tell about beautiful mountains, about the blue sea and many other things. Books are written to tell you about all the wonderful things in the world and also about people and their ideas. Books, magazines, TVs, radios and films all help us to communicate with each other. They all help us to know what is going on in the world and what other people are thinking about.41. Can we communicate with each other without words?A. Yes, sometimes we can.B. No, we can’t.C.

They are open five days a week and on Saturday mornings. From Monday to Friday, they are usually open from 8:30 to 4:30.If you know how much the postage (邮资) is for your letter, you can buy stamps at any window. In some post offices you can buy stamps from machines. Every post office sells stamps at many different prices, from one cent to many dollars. If you are not sure how much the postage for your letter is, you can ask the clerk (职员).If you are sending your letter far away, write on the envelope that you want it to go by air or use an airmail envelope. Remember that postage will be more expensive for an overseas (海外的) letter.At a post office you can also buy postcards. A postcard is cheaper than a letter.

The answer has changed over the years. Two thousand years ago, you were old at 35. At the beginning of the 20th century, the average life span (平均寿命) was 45. In 1950, 70-year-olds werereally old. Today, a healthy 70-year-old is still thought young.So, how old is “old”? The answer is one you’ve heard many times, from all kinds of people. “You are as old as (or young) as you feel.” Your age simply tells you how many years you have lived. Your body tells you how well you have lived.“Nobody grows old by living a number of years,” said a writer. “people grow old when they don’t have their ideals.” People shouldn’t have the wrong ideas about aging. Sometimes, older minds (头脑) can be bright as young minds, Alice Brophy once said, “It makes me unhappy when people say, “You look young for your age.” What does that mean? You know you can die old at 30 and live young at 80.51. About 100 years ago, the average life span was ___________A. 35B. 45C. 70D. 8052.
