It was believed that you should have your friends and family around you so that their good wishes and present-giving would keep the bad spirits away. People also believed that, by lighting candles, they were sending a signal or wishes to the gods. Later on, candles started to be used on birthday cakes. One story about the beginnings of the birthday cake is that it started with the Greeks, who made round cakes standing for the full moon for their moon goddess . They also placed candles on the cake to make it light, again like the moon. However, the Germans are said to have first used cakes and candles. They used a sweet cake and they put a large candle in the centre of the cake to mean "the light of life". The "Happy Birthday" song is more than a hundred years old. The music was written in 1893 by two sisters, Patty and Mildred Hill, who were schoolteachers in Louisville, Kentucky. The music was first used as a morning greeting to their students with the title, "Good Morning To All". In 1935, the words legally belonged to the Hill sisters, and the copyright has been bought and sold for millions of dollars ever since. The present copyright is owned by Warner Communications. They bought it in 1989 for more than $22 million. Question: When was the music written? Options: A: In 1893. B: In 1913. C: In 1935. D: In 1989.

This is no exaggeration , for reports show that man's greed has done much to destroy the earth. Man, in his greedy desire for financial growth, has polluted the air, land and water, and has robbed our valuable natural resources. Man's industrial plants pour out poisonous waste that pollutes the sea and puts life in the sea under the threat of dying out; at the same time, they release alarming amounts of carbon dioxide, chlorofluorocarbons (CFCs) and other pollutants. Small wonder that the air now is much warmer and more impure than ever before. Of course, this is not just because of man's greed--it is man's pressing need as well. For instance, in developing countries, huge financial foreign debts have forced governments to approve the cutting of forests for agriculture or ranching. As a result, forests are cut down just to meet man's immediate needs. Perhaps unknowingly,man has changed the make-up of the earth's atmosphere. Scientific studies have shown that CFCs used in refrigerators and industrial cleaners are fast destroying the ozone layer--a protective layer in the atmosphere that protects us against the harmful effects of the sun's ultraviolet rays. In fact, documented reports have shown a terrible fact that there are "holes" in the ozone layer over the Antarctic. And they appear to be expanding. Faced with these environmental problems, world leaders have shown deep concern. The UN Environmental Programme (UNEP) has arranged international agreements like the Vienna convention of 1985 and the Montreal Protocol of 1989 to preserve the ozone layer by controlling the production, use and trade of destructive chemicals. There may be some doubt as to how effectual these agreements may be, given that some countries still maintain an "I-don't-care" attitude. Their attitude is probably due to their failure to grasp the importance of the problem. Then, there is no doubt that environmental education on an international scale is greatly needed, so that... Question: The holes in the ozone layer are largely due to _ . Options: A: man's research activities B: the greenhouse effect C: the ultraviolent D: harmful chemicals

But Valentine's Day is not only about public displays of affection, and in recent years it has also become big business. In the UK alone, more than PS20 million is spent on flowers, while in the United States over $1 billion is forked out on chocolates. Although Valentine's Day has become a global industry with more than 80 million roses sold worldwide, the origins of the day are unclear. Nobody knows exactly who St Valentine was. It is said that the first recorded Valentine's card was sent by the imprisoned Duke of Orleans in 1415. It is believed that he sought solace from his imprisonment by writing love poems to his wife. Valentine's Day is now celebrated in many countries around the world. However, the traditions often differ from place to place. In Japan, for example, it is customary for the woman to send chocolates to the man, while in Korea April 14th is known as 'Black Day' when the unfortunate men who have received nothing on Valentine's Day gather to eat noodles and comfort each other. Technological developments have also played their part in keeping Valentine's Day relevant to the 21st century. Valentine's e-cards have been all the rage in recent years. Valentine's cards can also be used for less than romantic purposes. This year police in Liverpool sent Valentine's cards to criminals who failed to appear in court or have not paid fines. The cards contained the verse: "Roses are red; violets are blue. You've got a warrant and we'd love to see you." Who says romance is dead? Question: We can infer from the passage that _ . Options: A: Valentine's Day brings many benefits B: all countries celebrate Valentine's Day C: somebody knows who St Valentine was D: Valentine's cards are sent only by post
