Every drop of water in the ocean, even in the deepest parts, responds to the forces that create the tides. No other force that affects the sea is so strong. Compared with the tides, the waves created by the wind are surface movements feltno more than a hundred fathoms below the surface. The currents also seldom involve more than the upper several hundred fathoms despite their impressive sweep.

The tides are a response of the waters of the ocean to the pull of the Moon and the more distant Sun. In theory, there is a gravitational attraction between the water and even the outermost star of the universe. In reality, however, the pull of remote stars is so slight as to be obliterated by the control of the Moon and, to a lesser extent, the Sun. Just as the Moon rises later each day by fifty minutes, on the average, so, in most places, the time of high tide iscorrespondingly later each day. And as the Moon waxes and wanes in its monthly cycle, so the height of the tide varies. The tidal movements are strongest when the Moon is a sliver in the sky, and when it is full. These are the highest flood tides and the lowest ebb tides of the lunar month and are called the spring tides. At these times, the Sun, Moon, and Earth are nearly in line and the pull of the two heavenly bodies is added together to bring the water high on the beaches, to send its surf upward against the sea cliffs, and to draw a high tide into the harbors. Twice each month, at the quarters of the Moon, when the Sun, Moon, and Earth lie at the apexes of a triangular configuration and the pull of the Sun and Moon are opposed, the moderate tidal movements called neap tides occur. Then the difference between high and low water is less than at any other time during the month.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

  Since water is the basis of life, composing the greater part of the tissues of all living things, the crucial problem of desert animals is to survive in a world where sources of flowing water are rare. And since man’s inexorable necessity is to absorb large quantities of water at frequent intervals, he can scarcely comprehend that many creatures of the desert pass their entire lives without a single drop.

   Uncompromising as it is, the desert has not eliminated life but only those forms unable to withstand its desiccating effects. No moist- skinned, water-loving animals can exist there. Few large animals are found. The giants of the North American desert are the deer, the coyote, and the bobcat. Since desert country is open, it holds more swift-footed running and leaping creatures than the tangled forest. Its population is largely nocturnal, silent, filled with reticence, and ruled by stealth. Yet they are not emaciated. Having adapted to their austere environment, they are as healthy as animals anywhere else in the word. The secret of their adjustment lies in the combination of behavior and physiology. None could survive if, like mad dogs and Englishmen, they went out in the midday sun; many would die in a matter of minutes. So most of them pass the burning hours asleep in cool, humid burrows underneath the ground, emerging to hunt only by night. The surface of the sun-baked desert averages around 150 degrees, but 18 inches down the temperature is only 60 degrees.

Question: The title for this passage could be

A. “Man’s Life in a Desert Environment”

B. “Desert Plants”

C. “Animal Life in a Desert Environment”

D. “Life Underground”

Visiting London with children? Here’s a guide to some attractions for younger tourists.

The Barbican Centre has its annual children’s festival, Summer in the City, on 1-5 August. Each day’s timetable is handed out as you enter. It may include magic shows, face painting, hat making and music. One ticket (£4.50 for children, £1 for adults, and no children or adults allowed on their own) buys a full day’s activity so you can have a go at everything.

At the South Bank Centre young dancers can join in Sleeping Beauty workshops with the English National Ballet on 3 August. On 4 August Peter Badejo encourages all comers to join in African dance and there’s outdoor dance, theatre and music for all the family on the terraces around the Centre at weekends. For example, on 21 August the Teatro Buendia from Cuba will present a show for children of all ages called An Elephant Takes Too Much Room. At London Zoo there is a special exhibition about animals which have disappeared as well as animals in danger of disappearing. There are lifesize moving models of dinosaurs, but you can also see living examples of endangered species such as tigers and bird-eating spiders. While you may not want to get too near these, there are plenty of friendly animals in the new Children’s Zoo which will be happy to let you get close to them.

The Tower Hill Pageant is a dark ride museum showing the history of the City of London. Outside, the Town Crier calls visitors to Coin Striking when children can beat out copies of old coins in metal using traditional methods. Musicians and street performers will also be appearing throughout the summer.

The Museum of the Moving Image is about the cinema, its guides are actors dressed as cowboys and film stars. You can learn about film-making In special classes and there is a special exhibition at eye-level for very young children under one metre tall.

If adults are ready for a rest why not book Sunday lunch at the Russell Hotel? The Jumping Jelly Bean Club offers an exercise class (with qualified instructors) for children while you have a drink. Sit down to lunch together (£14.25 for adults, £3.95 for the children’s menu), then while you have your coffee the Jumping Jelly Beaners watch children’s films. The Club is held every Sunday lunchtime and it’s free to children with families eating in the hotel.
