They therefore believed that anything above them was nearer to their gods than the m. Naturally, they thought that birds were messengers from the gods. People also believed that birds carried their souls to the gods when they died. There were many beliefs about how to treat birds. Some people even believed that killing a bird was an act against the gods and would bring bad luck. In some parts of the United States, people still believe that if they hear an owl (猫头鹰) in the early evening, it means death. Another link with these past beliefs is in an English expression. People no longer believe that birds are messengers of the gods, but when someone knows a secret about another person, he or she might say, “A little bird told me about it.”We know, of course, that birds can‟t talk and that owls don‟t really mean death, yet we still have these superstitions. Many sailors believe that if they see an albatross (信天翁), it will bring bad luck to their trip. People all over the world use the dove (鸽) as a symbol of peace and feel good when they see one. North Americans think of the eagle as a symbol of freedom, and some people still hold that dreaming a bird means that they are seeing the loss of a soul.1. Primitive people thought that ________.A) their gods lived high above themB) their gods lived on tree topsC) their gods lived undergroundD) their gods could fly high2. Ancient people considered the birds as messengers because ________.A) birds could talkB) birds could carry their letters to the godsC) birds lived higher above themD) birds could bring letters from gods to them3. When people say “A little bird told me about it”, they ________.A) they do believe the message is brought by a birdB) they don‟t want to say the secretC) they try to prevent bad luckD) they are making a joke4. The birds mentioned in the passage which refer to bad luck are ________.A) eagles and dovesB) owls and eaglesC) eagles and albatrossesD) albatrosses and owls5. The passage talks about superstitions ________.A) in the United StatesB) in EnglandC) in Europe and AmericaD) all over the worldTask 2For most people, the word “fashion” means “clothes”. When people ask the question, “What‟s in fashion in Italy?” they normally say, “What clothes are in fashion?”But, of course, there are fashions in many things, not only in clothes. There are fashions in holidays, in restaurants, in films and books, even in university courses. A few years ago, it was quite fashionable to study Russian while now quote a lot of students want to learn Chinese. There are programs about China on TV and a number of students now study in Western countries.There are fashions in all sorts of things. Even in a language text book! Look at the book you use to learn English. If it was published in Britain during the last five years, it probably has a lot of pictures. These will probably be handwritten letters and postcards. There may be a story and photographs of the characters at the beginning of the book.Nowadays, fashions change very quickly. Some of this is natural. We hear about things much more quickly than in the past. Newspapers, radio, telex and television send information from one country to another in a few hours.But there are other reasons. New fashions mean that people will buy new things. Fashion is helped by clever advertising and journalism. There is money in fashion.6. For most people, the words “fashion” means ________.A. filmsB. clothesC. university coursesD. holidays7. Which of the following statements is NOT the explanation for more and more foreigners learning Chinese?A. It is becoming a fashion.B. People want to visit China.C. A lot of students study in Western countries now.D. Chinese is easy to learn.8. In an English book published five years ago, readers may find _____ at the beginning of it.A. a story and photographs of the charactersB. a life story of the writerC. a brief introduction of the pressD. the price9. Newspaper, radio, telex and television send ______ in a few hours.A. informationB. ideasC. laughterD. exciting stories10. Clever advertising and _______ help fashion.A. managersB. salesmenC. reportersD. productsTask 3After reading the following passage, you should complete the information by filling in the blanks marked 11 though 15 below.
