Quick and Quack were two brave little ducks who lived with their mother. Both were really fast and were always competing against each other. One day, after visiting their uncle Ducklass, Quack shouted, "Last one home is a goose!" and both ducks swam quickly down the river. They both knew the way well, but Quack had been preparing a trick for some time. He had realized that the current in the middle of the river was stronger, and would help him. So, even though Mother Duck had told them never to swim in the middle of the river, Quack paddled over to it. "I'm old enough now to swim here," he thought to himself. It wasn't long before he realized his mother had been right. He was going much faster than Quick, and was developing a big lead. Quick was not amused. He never disobeyed his mother, and now he was going to lose the race! As they went on, the current got stronger. Quack proudly crossed the finishing line, without realizing he headed straight for a big whirlpool in the middle of the river. Before he could react, he was turning around in it, unable to escape. No duck was strong enough to swim in those waters, and poor Quack kept swallowing water. The fact that he was struggling hard didn't help matters much either. Fortunately, a cow from a nearby farm came by, and seeing Quack, he jumped in and rescued him. When he was on dry ground, he remained uncomfortable for quite some time. That provided quite a laugh for different animals that had been watching. Before the race in the river began, _ . A) Quick had been well prepared for it B) Quack was quite sure of his success C) Quick decided to teach Quack a lesson D) Quick and Quack planned a trick for each other

Wild elephants live in herds of 10 to about 50. The leader is usually a female. A herd can go through a forest quietly. It travels in a single line. It goes about 6 miles an hour. When frightened, it may run at about 25 miles an hour. When they reach water, elephants swim across. They are great swimmers. Elephants eat grass, leaves, small branches, and bark. They particularly like the tender leaves on the top of trees. How do they get these leaves? They use their heads to knock trees down. They can easily knock down a 30-foot tree. Elephants also eat berries, mangoes, coconuts, corn, and sugar cane. They love salt. A wild male adult eats 500 to 600 pounds of food a day. Many people want to find the graveyards of elephants. There is a strong belief that such graveyards exist. Here is why. Bones and tusks of dead elephants have almost never been found. Searches have been made in forests. Grassy plains have been searched too. But neither bones nor tusks are found. Elephants don't live forever. Where are their bones? They don't just bury themselves. Here is one belief. When an elephant gets sick or old, it instinctively knows death is near. It leaves the herd. It goes off to a secret graveyard. The place is known only to elephants, and perhaps other animals, but not to humans. Obviously, such a graveyard would be filled with tusks. These were once very valuable. The objective of explorers was to find this "gold" mine. This graveyard belief may be a truth or a myth. But it is romantic. It would be nice if it were true. From the passage we can learn that _ . A) other animals know where elephants' graveyards are B) elephants bury themselves when their deaths are near C) people have found bones and tusks of dead elephants D) whether there are graveyards of elephants is still not known

Ques: Everyone has heard of the San Andreas fault , which constantly threatens California and the West Coast with earthquakes. But how many people know about the equally serious New Madrid fault in Missouri? Between December of 1811 and February of 1812, three major earthquakes occurred, all centered around the town of New Madrid, Missouri, on the Mississippi River. Property damage was severe. Buildings in the area were almost destroyed. Whole forests fell at once, and huge cracks opened in the ground, releasing some strong smell chemicals. The Mississippi River itself completely changed character, developing sudden rapids and whirlpools . Several times it changed its course, and once, according to some observers, it actually appeared to run backwards. Few people were killed in the New Marid earthquakes, probably simply because few people lived in the area in 1811; but the severity of the earthquakes are shown by the fact that the shock waves rang bells in church towers in Charleston, South Carolina, on the coast. Buildings shook in New York City, and clocks were stopped in Washington, D.C. Scientists now know that America's two major faults are essentially different. The San Andreas is a horizontal boundary between two major land masses that are slowly moving in opposite directions. California earthquakes result when the two masses make a sudden move. The New Madrid fault, on the other hand, is a vertical fault; at some points, possibly hundreds of millions of years ago, rock was pushed up toward the surface, probably by volcanoes under the surface. Suddenly, the volcanoes cooled and the rock collapsed, leaving huge cracks. Even now, the rock continues to settle downwards, and sudden sinking motions cause earthquakes in the region. The fault itself, a large crack in this layer of rock, with dozens of other cracks that split off from it, extends from northeast Arkansas through Missouri and into southern Illinois. Scientists who have studied the New Madrid fault say there have been numerous smaller quakes in the... The New Madrid fault is _ . A) a vertical fault B) a horizontal fault C) a more serious fault than the San Andreas fault D) responsible for forming the Mississippi River
Ans: A
Ques: What's the difference between the British Isles, Britain, the United Kingdom and England? The British Isles is made up of two large islands: One is called Ireland and the other Britain. Britain, or Great Britain, is the larger of these two islands and it is divided into three parts: Scotland, Wales and England. The United Kingdom (UK) is short for the United Kingdom of Great Britain and Northern Ireland. It is made up of Scotland, Wales, and England (i.e. the whole of Britain), and also about one-sixth of Ireland, the Northern part. The rest of Ireland is self-governing . England is the largest, most populous , and generally speaking, the richest section. English people often use the words "England" and "English" when they mean "Britain" and "British". This sometimes makes the Scots and the Welsh angry. The Scots are very proud of their separate nationality. The Welsh too do not consider themselves as England, and have a culture and even a language of their own. Ireland became part of the United Kingdom in 1801, but is soon grew discontented , and for forty years the "Irish Question" was the greatest headache of British Parliament . At last, Ireland divided itself into two: Northern Ireland remained loyal to the Crown , and in 1922 the rest of the country broke away to form Irish Free State, now the Republic of Ireland. Which is the largest island of the British Isles?. A) Ireland B) Britain C) England D) Northern Ireland
