When the weather is hot, you go to a lake or an ocean. When you are near a lake or an ocean, you feel cold. Why? The sun makes the earth hot but it can not make the water very hot. Although the air over the earth becomes hot, the air over the water stays cool. The hot air over the earth goes up. Then the cool air over the water moves in and takes the place of the hot air. When it moves in, you feel the wind. And the wind makes you cool.
Of course, scientists can not answer all of our questions. If we ask, “Why is the ocean full of salt?” Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks (断裂). Rain falls into the cracks. The rain then carries the salt into the ocean. But then we ask, “What happens to the salt in the ocean?” The ocean does not get more salty every year. Scientists are not sure about the answer to this question.
We know a lot about our world. But there are still many answers that we don’t have and we are curious about.

Winter depression (or winter blues) is a common affliction (折磨) for those who live in our northern climate. Its clinical name is seasonal affective disorder (or SAD) and up to 5% of the population (especially in northern states) may suffer from it. Seasonal affective disorder is characterized by feelings of sadness and depression that occur in the winter months when the temperatures drop and the days grow short 
. The depression is often associated with excessive eating or sleeping and weight gain. Women are twice to three times more likely to suffer from the winter blues than men.
There are many effective treatments for winter depression, some of which you can do to help yourself. Increasing your daily exposure to as much natural light as possible can be helpful to many. Any time that you have the opportunity to gain access to more sunlight in the winter months, you should try to do so. Taking walks throughout the day (even if you don’t normally do so), sitting next to a south-facing window at your office, in a classroom, or at home will increase your sunlight exposure. Exercising next to a window or outdoors (when possible) is another activity that can help.
Although it may be difficult to do, maintaining your schedule and lifestyle will help to keep the depression at bay. A regular pattern of sleep is the most important thing to maintain. It may be helpful, for instance, to have your bedroom lights on a timer to turn on a half-hour before you wake. This may help in waking at a regular time every morning, when it is still dark outside in the winter months.
Light therapy has shown to be an effective treatment for seasonal affective disorder. While you can purchase expensive, specialized light therapy lighting fixtures for your home or office, some inexpensive alternatives are also available. Another lighting technique to try is to replace commonly used light bulbs in your home with brighter full spectrum (also known as broad spectrum) light bulbs. While more expensive than regular light bulbs, these bulbs provide light that is similar to natural sunlight.
If none of these techniques seem to help your depressive symptoms, you should consider consulting your family physician or a mental health professional. The winter blues are a form of depression and can be readily treated w ith medications or psychotherapy when other self-help methods aren’t effective. Don’t be afraid to talk about this condition with a professional; it’s nothing to be ashamed or afraid of. With a little effort, the winter blues can be beaten
What do we know about winter depression?
A. It is very common where the weather is cold.
B. It may lead to weight gain.
C. It occurs when the temperatures drop.
D. It seldom affects men.
What is the most important factor in the therapy introduced in the second paragraph?
A. Exposure to natural light.
B. Sports in winter months.
C. Outdoor activities.
D. Sunlight through the window.
What does “to keep the depression at bay” mean in the third paragraph?
A. To shorten the duration of the depression.
B. To use light to resist the depression.
C. To keep the depression manageable and minimal.
D. To delay the occurrence of the depression.
For winter depression, light therapy ___________.
A. is much more effective than other kinds of therapy
B. is so expensive that some may not be able to afford it
C. encourages people to do outdoor exercises
D. needs specialized bulbs to replace ordinary ones
We can infer from the passage that __________.
A. self-help methods do not work 100% of the time
B. medications or psychotherapy is much more effective
C. mental health professionals don’t recommend self- help methods
D. most people prefer self-help methods to medications

The First of May is a Bank Holiday—the first public holiday of the year in England. Most people consider it a special day, the beginning of summer, a day when the light lasts long into the evening, and when we can look for warm weather. We don't always get it. We feel disappointed, but not surprised if there are cold winds and frosts at night in May. Winter should be over. Most people know that in the past, when farming occupied almost everyone, the changing seasons were of great importance. In that older time there was every reason to celebrate May Day. Customs of those celebrations remain.?
Of these customs, the best known is the choosing of a May Queen and the dancing round Maypole. Even these customs are little more than memories now—but in the last century it was quite common in villages and small towns, and even in schools and colleges, for a pretty and popular girl to be chosen Queen of the May. It was a great honour to be chosen. For a day she wore a light and flowery dress, carried garlands（花环）, and was ceremonially crowned with flowers. She presided over a procession, as a rule with a number of attendants, and over the Maypole dancing and all kinds of entertainment. The Maypole was slender（苗条的w.w.^w.k.&s.5*u.c.#o） tree trunk, cut off its branches, with beautiful ribbons fastened to the top. The dancing was designed in such a way that the dancer's movements move the ribbons into a pattern. This, as you can imagine, required skill from the dancer, and was not achieved without practice.
It's the Celtic people who celebrated the First of May as a spring festival. Their celebration seems to have had little to do with taking pleasure in early, beautiful flowers and in warmer weather! They called it Beltane—the fire of the god Bel. They lit fires, in the expectation that their blaze would help the sun in its struggle to regain its strength. They drove their cattle between banks of flame in the expectation that the terrified beasts would be purified and protected from disease. A tree, which must have been blackened with smoke, stood in the middle of the fires, and is thought to have been the origin of the Maypole. Their priests（牧师） made sacrifices to the goods in the hope of good harvests and sufficient store of food for the winter. There was dancing certainly, but it was noisy and cheerful, since its purpose was not to weave a pattern of colored ribbons, but to drive out evil spirits from the earth and to arouse those kind spirits.?
57. The main purpose of the passage is to show ________.?
A. the reason why they celebrate May Day
B. the start and customs of May Day
C. the way they celebrate May Day
D. the choosing of a May Queen during May Day
58. According to the passage, which sentence is NOT true??
A. In the old days they celebrated May Day for the changing of the seasons.?
B. In England summer begins at the first of May.?
C. The custom of the choosing of a May Queen still exists in the present May Day celebration.?D. The Celtic people celebrated the first of May as a spring festival.??
59. From the surrounding words and sentences we know that the word “presided” means ____.
A. 管理 B. 越过 C. 指挥 D. 主持?
60. The best title for this passage is ________.
A. The First of May B. The Beginning of Summer
C. May Queen D. The Holiday of the Year?
