When another old cave is discovered in the south of France, it is not usually news. Rather, it is an ordinary event. Such discoveries are so frequent these days that hardly anybody pays heed to them. However, when the Lascaux cave complex was discovered in 1940,the world was amazed. Painted directly on its walls were hundreds of scenes showing how people lived thousands of years ago. The scenes show people hunting animals, such as bison or wild cats. Other images depict birds and, most noticeably, horses, which appear in more than 300 wall images, by far outnumbering all other animals.

Early artists drawing these animals accomplished a monumental and difficult task. They did not limit themselves to the easily accessible walls but carried their painting materials to spaces that required climbing steep walls or crawling into narrow passages in the Lascaux complex.

Unfortunately, the paintings have been exposed to the destructive action of water and temperature changes, which easily wear the images away. Because the Lascaux caves have many entrances, air movement has also damaged the images inside.

Although they are not out in the open air, where natural light would have destroyed them long ago, many of the images have deteriorated and are barely recognizable. To prevent further damage, the site was closed to tourists in 1963,23 years after it was discovered. 44. Based on the passage, what is probably true about the south of France? A. It is home to rare animals. B. It has a large number of caves. C. It is known for horse-racing events. D. It has attracted many famous artists.

45. According to the passage, which animals appear most often on the cave walls? A. Birds. B. Bison. C. Horses. D. Wild cats.

46. Why was painting inside the Lascaux complex a difficult task? A. It was completely dark inside.

B. The caves were full of wild animals. C. Painting materials were hard to find.

D. Many painting spaces were difficult to reach.

47. According to the passage, all of the following have caused damage to the paintings EXCEPT A. temperature changes B. air movement C. water D. light

Passage Four

Gold used in jewelry is mixed with harder metals to add strength and durability. The metals added can also be used to change gold' s color, giving it a fashionable rose or white tint, or to lighten or darken the natural yellow tone of pure gold. Mixtures like these, of less costly metals with more valuable ones, are called alloys. Copper and silver are the most common metals mixed with gold to make yellow gold jewelry. White gold is usually made with an alloy of gold and nickel.

The measure of gold' s purity is called a karat. The higher the karat rating, the higher the amount of pure gold: 24 karat is pure gold, 15 karat is 75% pure gold, 14 karat is 58.5% pure gold, and 9 karat is 37.5% pure gold. All other things being equal, the higher the percentage of pure gold used in the alloy, the more valuable and expensive the jewelry will be.

Gold jewelry pieces are usually stamped with a marking to identify the karat amount. While gold that is 24K is too soft for jewelry, 18K, 14K and 9K gold are all appropriate for jewelry, and they all make pieces that look great and wear beautifully.

48. Which of the following statements best captures the main idea of this passage? A. Although gold is very valuable, it is also very expensive. B. Gold jewelry is stamped with its karat weight. C. Gold jewelry is made using alloys.

D. Colored gold is more valuable than white gold.

49. Based on information in the passage, it can be understood that pure gold is A. not used to make rings B. stamped with 100K

C. an alloy of different metals D. colorless

50. According to the passage, the use of other metals in gold alloys

Ⅰ. can be used to make the gold different color Ⅱ. makes jewelry more expensive Ⅲ. makes gold more flexible A. I only

B. I and Ⅱ only C. Ⅱ and Ⅲ only D. I , Ⅱ ,and Ⅲ

51. Which of the following statements best explains the relationship between gold and its karat rating?

A. The lower the karat rating,the purer the gold.

B. The higher the karat rating,the more expensive the gold. C. The higher the karat rating,the less valuable the mixture. D. The lower the karat rating,the purer the alloy. Passage Five

It is bad to have food stuck between your teeth for long periods of time. This is because food attracts germs, germs produce acid ,and acid hurts your teeth and gums. Flossing helps to remove the food that gets stuck between your teeth. This explains why flossing helps to keep your mouth healthy, but some doctors say that flossing can be also good for your heart.

It may seem strange that something you do for your teeth can have any effect on your heart.

Doctors have come up with a few ideas about how flossing works to keep your heart healthy. One idea is that the germs that hurt your teeth can leave the mouth and travel into your blood. Germs that get into the blood can then attack your heart. Another idea is based on the fact that when there are too many germs in your mouth, the body tries to fight against these germs. For some reason, the way the body fights these mouth germs may end up weakening the heart over time. Not every doctor agrees about these ideas. Some doctors think that the link between good flossing habits and good heart health is only a coincidence. A coincidence is the occurrence of two or more events at one time apparently by mere chance. The incidence of these events is completely random, as they do not admit of any reliable cause and effect relationship between them. For example, every time I wash my car, it rains. This does not mean that when I wash my car, I somehow change the weather. This is only a coincidence.

The theory that flossing your teeth helps to keep your heart healthy might not be true. But every doctor agrees that flossing is a great way to keep your teeth healthy. So even if flossing does not help your heart, it is sure to help your teeth. This is enough of a reason for everyone to floss their teeth every day.

52. Flossing effectively helps to keep your mouth healthy by preventing A. germs from producing acid B. food from entering your body

C. germs from entering into your blood

D. acid from contacting your teeth and gums

53. In paragraph 2, the author explains how having too many germs in your mouth can “end up

weakening the heart. \ Using the passage as a guide, it can be understood that doctors are A. reluctant to hypothesize B. confident in their estimations C. extremely knowledgeable D. uncertain but speculative

54. Using information in paragraph 3 as a guide, which of the following is the best example of a coincidence?

A. Jim wakes up with a sore throat. He eats a piece of bacon for breakfast. By noon, he feels much better. Jim decides that the bacon has cured his sore throat.

B. Laura remembers to brush her teeth every day, but she only remembers to floss once a week. She writes a note to herself, reminding herself to floss and sticks it to her bathroom mirror.

C. Mario is not very good at baseball. He practices playing every day. After a several months of practice, he is a much better baseball player.

D. Jai has a bad heart. Her doctor tells her to eat more vegetables and less junk food. After nearly a year of doing this, the doctor tells Jai that her heart is doing much better. 55. Which of the following best states the main idea of the final paragraph?

A. Because doctors do not agree that flossing wilt help your heart, it is useless to floss. B. It is a fact that flossing can help your heart as well as your teeth.

C. Even if flossing is only good for your teeth, you should still do it every day.

D. There is no good reason to believe that flossing will help your heart, but it is still a good idea to do it every day.
