Caves (洞穴) have a primary appeal — they hold the secrets to our past and are mysterious in and of themselves.

● Mammoth Cave

Kentucky, USA

The longest cave system in the world lies beneath the Green River Valley in Kentucky and while over 400 miles of passageways have been mapped, it has yet to be fully discovered. The complex limestone labyrinth (石灰岩迷宫) was discovered by humans 4,000 years ago.

● Blue Grotto

Capri, Italy

Once used as the personal swimming hole for the Roman Emperor Tiberius, this extremely bright sea cave is almost 200 feet long and 82 feet wide. Its unique glow comes from the light entering the small opening to the outside.

● Avshalom Cave Nature Reserve

Beit Shemesh, Israel

Also known as the Soreq Cave Nature Reserve, Avshalom is considered to be the Rosetta Stone of climate history in the Eastern Mediterranean through the packed stalactites (钟乳石) found in the cave, some of which are over 13 feet long, and are as old as 300,000 years.

● Cave of the Crystals

Naica, Mexico

This unique cave system in Mexico contains some of the largest natural crystals (水晶) ever found—the longest of which is 39 feet long and 13 feet thick. However, it is rarely explored due to logistical difficulties: it is extremely hot due to its location above a volcanic vent, and the huge crystals block also block the passage.

Scientists have found what look like caves on Mars, and say they could be protecting life from the planet’s terrible environment.

The first caves discovered beyond the Earth appear as seven mysterious black dots on the pictures sent back by NASA’s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural caves below the Martian surface.

“If there is life on Mars, there is a good chance you’d find it in caves,” said Jut Wynne, one of the researchers who noticed the features while working on a US Geological Survey Mars Cave Detection Program.

Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as exciting.

One photo taken at night by an infrared imager(红外线成像器) showed one hole to be unusually warm, suggesting hot air trapped during the day is flowing out.

“I said: ‘Wow, that’s a cave’.” Dr. Clarke said excitedly. “People have been looking for these for a long time; now we have found them.”

He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold, radiation-soaked(充满辐射的), dry surface.

“Tiny drops of water could collect inside,” he said. “If there are gases coming out, they could provide energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is exposed to high levels of space radiation.”

The caves probably formed when tube-shaped lave flows(管状岩浆流) spread across the planet long ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the remaining have to flow out, forming caves.

1.What does the passage mainly talk about?

A. How the caves were formed on Mars.

B. How scientists found these caves on Mars.

C. Caves on Mars may be full of hot air or a sign of life.

D. Scientists have completely recognized the surface of Mars.

2.What can the “cave” be used for according to the scientists?

A. They can protect life from the planet’s terrible environment.

B. They can provide energy for people’s life.

C. They can be used to prevent space radiation

D. Both A and C.

3.We can learn from the passage that　　　　 .

A. water has already been found on Mars

B. the scientists found all the caves at night

C. it is certain that there is life in these caves

D. the surface of Mars is bitterly cold, radiation-soaked and dry

4.According to the passage, Dr. Clarke was so excited because　　　　 .

A. such caves could provide energy for life

B. they had finally found the caves on Mars

C. such caves would be perfect places to hunt for life

D. scientists had long been looking for these caves

5.Necessary conditions for life on Mars mentioned in the passage may include　　　　 .

A. lave and energy

B. water and radiation from space

C. gases and lave

D. water and protection from radiation

Have you ever wondered why certain people always say they are lucky? Some people say the secret of being born lucky is probably a summer birthday. May babies are the most likely to enjoy a lifetime of good fortune, a study of 40,000 people has found. The time of year you are born has a lasting influence on optimism and whether people think they are lucky, British and Swedish scientists said. May is the luckiest month to be born in, with half of those born then considering themselves lucky. October is the least lucky month with only 43 percent claiming good fortune.

The study adds to evidence that luck is not all down to chance, but is also affected by a person’s attitude. Another research has shown that whether people think themselves lucky depends more on having a “glass half-full” (instead of “half-empty”) approach to life, than on success. Professor Richard Wiseman, who led the study, said, “Something is influencing how people feel about their luck. People create their own luck through their attitude towards life.”

Luck is a mental state and not a matter of blind chance. There could be two reasons why those born in spring and summer reported themselves luckier than those born in autumn or winter. “One theory is that the temperature at the time of birth might be helpful to the development of the brain.” He said. “People born in winter are more likely to suffer from depression”. He said another possible reason is that mothers may be in a bad mood during winter, which influences their babies. The researchers said their findings were based on statistics only, and would not be true for everyone.

What’s depression? Medical depression is when one feels so sad and hopeless that sometimes he can’t imagine being happy. The pain becomes so deep that you don’t feel like participating in life. People who are permanently depressed usually have physical problems like stomachaches, headaches, and lack of energy. As you probably know, some people experience such deep depression that they believe suicide (killing yourself) is the only way to escape their pain.

1.Why can your birthday influence your attitude towards life?

A. The time of your birthday determines how fortunate you will be.

B. Mothers may feel differently in different seasons, and their moods influence their babies.

C. How successful you will be lies in the hour of your birthday.

D. How you feel about your health is influenced by the time of your birthday.

2.Having a “half-full” approach to life is a (an) ______ attitude.

A. optimistic　　 B. pessimistic　　 C. lucky　　 D. depressing

3.Which of the following is NOT true according to the passage?

A. People born in summer are probably more optimistic than those born in winter.

B. A person’s luck may be affected by his attitude.

C. Depression may harm one’s physical health.

D. Luck is never a matter of chance.

4.According to the research result, one’s luck mainly depends on ______.

A. chance　　 B. the month to be born in

C. one’s attitude to life　　 D. health state

The appeal of advertising to buying motives can have both negative and positive effects. Consumers may be convinced to buy a product of poor quality or high price because of an advertisement. For example, some advertisers have appealed to people’s desire for better fuel economy for their cars by advertising automotive products that improve gasoline mileage. Some of the products work. Others are worthless and a waste of consumers’ money.

Sometimes advertising is intentionally misleading. A few years ago a brand of

bread was offered to dieters (节食者) with the message that there were fewer calories in every slice. It turned out that the bread was not dietetic (适合于节食的), but just regular bread. There were fewer calories because it was sliced very thin, but there were the same number of calories in every loaf.

　On the positive side, emotional appeals may respond to a consumer’s real concerns. Consider fire insurance. Fire insurance may be sold by appealing to fear of loss. But fear of loss is the real reason for fire insurance. The security of knowing that property is protected by insurance makes the purchase of fire insurance a worthwhile investment for most people. If consumers consider the quality of the insurance plans as well as the message in the ads, they will benefit from the advertising.

　Each consumer must evaluate her or his own situation. Are the benefits of the product important enough to justify buying it? Advertising is intended to appeal to consumers, but it does not force them to buy the product. Consumers still control the final buying decision.

56. Advertising can persuade the consumer to buy worthless products by _________.

A. stressing their high quality

B. convincing him of their low price

C. maintaining a balance between quality and price

D. appealing to his buying motives

57. The reason why the bread advertisement is misleading is that ________.

A. thin slices of bread could contain more calories

B. the loaf was cut into regular slices

C. the bread was not genuine bread

D. the total number of calories in the loaf remained the same

58. The passage tells us that _______.

A. sometimes advertisements really sell what the consumer needs

B. advertisements occasionally force consumers into buying things they don’t need

C. the buying motives of consumers are controlled by advertisements

D. fire insurance is seldom a worthwhile investment

59. It can be inferred from the passage that a smart consumer should ________.

A. think carefully about the benefits described in the advertisements

B. guard against the deceiving nature of advertisements

C. be familiar with various advertising strategies

D. avoid buying products that have strong emotional appeal

60. The passage is mainly about ________.

A. how to make a wise buying decision

B. ways to protect the interests of the consumer

C. the positive and negative aspects of advertising

D. the function of advertisements in promoting sales
