Text 2 Good teachers matter. This may seem obvious to anyone who has a child in school or, for that matter, to anyone who has been a child in school. For a long time, though, researchers couldn’t actually prove that teaching talent was important. But new research finally shows that teacher quality is a close cousin to student achievement: A great teacher can cram one-and-a-half grades’ worth of learning into a single year, while laggards are lucky to accomplish half that much. Yet, while we know now that better teachers are critical, flaws in the way that administrators select and retain them mean that schools don’t always hire the best. Failing to recognize the qualities that make teachers truly effective and to construct incentives to attract and retain more of these top performers has serious consequences. Higher salaries draw more weak as well as strong applicants into teaching — applicants the current hiring system can’t adequately screen. Unless administrators have incentives to hire the best teachers available, it’s pointless to give them a larger group to choose from. Study after study has shown that teachers with master’s degrees are no better than those without. Job experience does matter, but only for the first few years, according to research by Hoover Institution’s Eric A. Hanushek. A teacher with 15 years of experience is no more effective, on average, than a teacher with five years of experience, but which one do you think is paid more This toxic combination of rigid pay and steep rewards for seniority causes average quality to decline rather than increase as teacher groups get older. Top performers often leave the field early for industries that reward their excellence. Mediocre teachers, on the other hand, are soon overcompensated by seniority pay. And because they are paid more than their skills command elsewhere, these less-capable pedagogues settle in to provide many years-of ineffectual instruction. So how can we separate the wheat from the chaff in the teaching profession To make American schools competitive, we must rethink seniority pay, the value of master’s degrees, and the notion that a teacher can teach everything equally well — especially math and science — without appropriate preparation in the subject. Our current education system is unlikely to accomplish this dramatic rethinking. Imagine, for a moment, that American cars had been free in recent decades, while Toyotas and Hondas sold at full price. We’d probably be driving Falcons and Corvairs today. Free public education suffers from a lack of competition in just this way. So while industries from aerospace to drugs have transformed themselves in order to compete, public schooling has stagnated. School choice could spark the kind of reformation this industry needs by motivating administrators to hire the best and adopt new strategies to keep top teachers in the classroom. The lesson that good teachers matter should be taught, not as a theory, but as a practice. According to the text, which of the following is true
Text 3 To understand how astrology works, we should first take a quick look at the sky. Although the stars are at enormous distances, they do indeed give the impression of being affixed to the inner surface of a great hollow sphere surrounding the earth. Ancient people, in fact, literally believed in the existence of such a celestial sphere. As the earth spins on its axis, the celestial sphere appears to turn about us each day, pivoting at points on a line with the earth’s axis of rotation. This daily turning of the sphere carries the stars around the sky, causing most of them to rise and set, but they, and constellations they define, maintain fixed patterns on the sphere, just as the continent of Australia maintains its shape on a spinning globe of the earth. Thus the stars were called fixed stars. The motion of the sun along the ecliptic is, of course, merely a reflection of the revolution of the earth around the sun, but the ancients believed the earth was fixed and the sun had an independent motion of its own, eastward among the stars. The glare of sunlight hides the stars in daytime, but the ancients were aware that the stars were up there even at night, and the slow eastward motion of the sun around the sky, at the rate of about thirty degrees each month, caused different stars to be visible at night at different times of the year. The moon, revolving around the earth each month, also has an independent motion in the sky. The moon, however changes it position relatively rapidly. Although it appears to rise and Set each day, as does nearly everything else in the sky, we can see the moon changing position during as short an interval as an hour or so. The moon’s path around the earth lies nearly in the same plane as the earth’s path around the sun, so the moon is never seen very far from the ecliptic in the sky. There are five other objects visible to the naked eye that also appear to move in respect to the fixed background of stars on the celestial sphere. These are the planets Mercury, Venus, Mars, Jupiter, and Saturn. All of them revolve around the sun in nearly the same plane as the earth does. So they, like the moon, always appear near the ecliptic. Because we see the planets from the moving earth, however, they behave in a complicated way, with their apparent motions on the celestial sphere reflecting both their own independent motions around the sun and our motion as well. According to the last paragraph, five other planets
Text 4 Here is a quick way to spoil a Brussels dinner party. Simply suggest that world governance is slipping away from the G20, G7, G8 or other bodies in which Europeans may hog up to half the seats. Then propose, with gloomy relish, that the future belongs to the G2: newly fashionable jargon for a putative body formed by China and America. The fear of irrelevance haunts Euro-types, for all their public boasting about Europe’s future might. The thought that the European Union might not greatly interest China is especially painful. After all, the 21st century was meant to be different. Indeed, to earlier leaders like France’s Jacques Chirac, a rising China was welcome as another challenge to American hegemony, ushering in a “multipolar world” in which the EU would play a big role. If that meant kow-towing to Chinese demands to shun Taiwan, snub the Dalai Lama or tone down criticism of human-rights abuses, so be it. Most EU countries focused on commercial diplomacy with China, to ensure that their leaders’ visits could end with flashing cameras and the signing of juicy contracts. Meanwhile, Europe’s trade deficit with China hit nearly∈170 billion ( $ 250 billion) last year. In five years, China wants 60% of car parts in new Chinese vehicles to be locally made. This is alarming news for Germany, the leading European exporter to China thanks to car parts, machine tools and other widgets. As ever, Europeans disagree over how to respond. Some are willing to challenge China politically — for example, Germany, Britain, Sweden and the Netherlands. But they are mostly free traders. That makes them hostile when other countries call for protection against alleged Chinese cheating. In contrast, a block of mostly southern and central Europeans, dubbed “accommodating mercantilists” by the ECFR (The European Council on Foreign Relations), are quick to call for anti-dumping measures: But that makes them anxious to keep broader relations sweet by bowing to China on political issues. The result is that European politicians often find themselves defending unconditional engagement with China. The usual claim is that this will slowly transform the country into a freer, more responsible stakeholder in the world. The secret, it is murmured, is to let Europe weave China into an entangling web of agreements and sectoral dialogues. In 2007 no fewer than 450 European delegations visited China. Big countries like France and Britain add their own bilateral dialogues, not trusting the EU to protect their interests or do the job properly. There are now six parallel EU and national “dialogues” with China on climate change, for example. In the eyes of European politicians, China
