What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, that knowing how to investigate, how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the Theory of Relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, and Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.

Reading comprehensionPassage One ( 2 points each, 10 points)Read the article and then judge the statements are true(T) or false (F). Write your answers on the Answer Sheet.Its a sad fact that many societies have singled out left-handed people as being “different” or “unusual”, or worse, have held them in low esteem. For example, in Christian tradition, the devil is generally associated with the left hand and the word sinister comes from the Latin for left, sinistra. This prejudice is all the more surprising when you consider that left-handedness is also linked with creativity. Leonardo da Vinci was left-handed, as were Michelangelo, Isaac Newton and Albert Einstein. While right-handed people seem to have better cognitive skills on average, studies find that left-handed people are more common among the highly innovative.About 11 percent of the population is left-handed (with slightly more men than women). Learning and working in a world of machines designed for a principally right-handed population, left-handed people are at a disadvantage. Tools like the screwdriver work well for both. But others, like scissors and the standard classroom writing desk - not to mention writing from left to right, with all the smudges and blackened fingers that entails - are explicitly designed for right - handed people. This ought to make left-handed people less productive and therefore make less money. However, thats clearly not always the case - at least for men. A recent study in Britain and Ireland looked at about 5,000 people born in 1958 and found modest earnings differences: 5 percent higher pay for left-handed males, relative to their right-handed counterparts and, surprisingly, 5 percent lower pay for left-handed females compared to right-handed females. Whats more noteworthy is that the pay difference for males appears to increase with college education. In a US study, college graduates overall earned an average of 30 percent more than high-school graduates. Interestingly, after accounting for other determinants of pay - such as age and marital status - left-handed males with a college education earned 10 to 15 percent more than their right-handed counterparts. By contrast, the study found no systematic difference between the pay of left-handed and right-handed females. The identification of two styles of thinking may help explain why college-educated left-handed males make more. Most people make use of “convergent” thinking - focusing on existing knowledge and rules in order to come up with a single, correct answer. Left-handed males are more likely to engage in “divergent” thinking, in other words moving outwards into unexplored association. In an experiment in which subjects devised uses for pairs of common objects, such as imagining that a stick and a can could together be a birdhouse, those who are left-handed on average came up

Good evening, ladies and gentlemen, I’m Roy , and this is my show. This is a television show for all families, and I know you’ll enjoy it.
Let’s start with a story. Once there was a proud pig on a farm . He thought he was the most important of all the animals on the farm. But it was not enough that he himself thought this: he had to be sure that other animals thought it, too. So he went up to a chicken and asked, “ Who is the most important animal on the farm?” The chicken answered, “ You are, Mr. Pig .” Then he asked a dog, and he got the same reply.
Next, he asked a cow. When the cow seemed uncertained of the right answer, the pig looked angry, and showed his teeth, “ Oh, you are, of course, Mr. Pig.” said the cow. “ Of course, ” the pig said, “ there is no doubt about it. ”
At last the pig asked a big horse the same question. The horse lifted one foot, rolled the pig over and placed his foot on the pig’s head. “ I think you know the answer now. ” said the horse.
