Passage Three
Considered as a continuous body of fluid, the atmosphere is another kind of ocean. Yet, in view of the total amount of rain and snow on land areas in the course of a year, one of the most amazing water facts is the very small amount of water in the atmosphere at any given time. The volume of the lower seven miles of the atmosphere--the realm of weather events- is roughly four times the volume of the world’s oceans. But the atmosphere contains very little water. It is chiefly in the form of invisible vapor, some of which is carried over land by air currents. If all vapor suddenly fell from the air onto the earth’s surface, it would form a layer only about one inch thick. A heavy rainstorm on a given area may use up only a small percentage of the water from the air mass that passes over. How, then, can some land areas receive more than 400 inches of rain per year How can several inches of rain fall during a single storm in a few minutes or h
A. The volume of the atmosphere is four times that of the world's.
B. The water in the oceans is the main source of rain and snow on land areas.
C. The atmosphere is mainly composed of the vapor carded over land by air currents.
D. The earth cannot support the water in the atmosphere if it falls down onto the earth suddenly.

Passage Three
Like the body, the memory improves with use. Unlike the body, the memory can improve with age.
For many years, doctors have been studying the way the brain works. We all know that the brain has two sides, the left and the right. The right side controls the senses (seeing, hearing, feeling, tasting and smelling), and is the creative and imaginative side. The left side of the brain controls our logical thinking. It processes the information which comes in, and puts it into order, We call the left side the "educated" side of the brain and generally, in western societies, people have developed this side of the brain more than the fight side.
Scientists believe that our brain will work much more efficiently if both the right side and the left side are developed equally. In many schools today, teachers try to educate the children in such a way that both sides of the brain are used. This can be done with logical subjects including m
A. both sides of the brain are used equally
B. the left side is fully developed
C. scientists work on it
D. the right side is fully developed

Passage Three
Most English people have three names: a first name, a middle name and the family name. Their family name comes last. For example, my full name is Jim Allan Green. Green is my family name. My parents gave me both of my other names.
People don’t use their middle names very much, So "John Henry Brown" is usually called "John Brown". People never use Mr. , Mrs. or Miss before their first names. So you can say John Brown, or Mr. Brown; but you should never say Mr. John. They use Mr. , Mrs. or Miss with the family name but never with the first name.
Sometimes people ask me about nay name. "When were you born, why did your parents call you Jim" they ask. "Why did they choose that name" The answer is they didn’t call me Jim. They called me James. James was the name of nay grandfather. In England, people usually call me Jim for short. That’s because it is shorter and easier than James.A. one

Passage Three
The traditional American Thanksgiving Day celebration goes back to 1621. In that year a special feast was prepared in Plymouth, Massachusetts. The colonists who had settled there had left England because they were denied of religious freedom. They came to the new land and faced difficulties in coming across the ocean.
The ship that carried them was called the Mayflower. The North Atlantic was difficult to travel. There were bad storms. They were assisted in learning to live in the land by the Indians who lived in the region. The Puritans, as they were called, had much to be thankful for. Their religious practices were no longer a source of criticism by the government. They learned to adjust their farming habits to the climate and soil.
When they selected the fourth Thursday of November for their Thanksgiving Celebration, they invited their neighbors, the Indians, to join them in dinner and a prayer of gratitude for the new life. They r
A. made life difficult for them
B. helped them to adjust
C. taken their land
D. been too afraid to talk to them

Passage Three
Cooperative competition. Competitive cooperation. Confused Airline alliances have travelers scratching their heads over what’ s going on in the skies. Some folks view alliances as a blessing to travelers, offering seamless travel, reduced fares and enhanced frequent-flyer benefits. Others see a conspiracy of big business, causing decreased competition, increased fares and fewer choices. Whatever your opinion, there’ s no escaping airline alliances: the marketing hype is unrelenting, with each of the two mega-groupings. One world and Star Alliance, promoting itself as the best choice for all travelers. And, even if you turn away from their ads, chances are they will figure in any of your travel plans. By the end of the year, one world and Star Alliance will between them control more than 40% of the traffic in the sky. Some pundits predict that figure will be more like 75% in 10 years.
But why, after years of often ferocious competit
A. Delight.
B. Indifference.
