Our planet and seven others orbit the Sun, which is only one of about 200 billion stars in our galaxy. Our galaxy, the
3、 Milky Way, is part of the universe, which includes millions of othergalaxies and their stars and planets. By comparison, the Earth is microscopic.Compared to a person, on the other hand, the Earth is enormous. It has a diameter of 7,926 miles ( 12,756 kilometers) at the equator, and it has a mass o
4、f about 6 x 1024 kilograms. The Earth orbits the Sun at a speed of about 66,638 miles per hour (29.79 kilometers per second). Dont dwell on those numbers too long, though; to a lot of people, the Earth is inconceivably, mind-bogglingly big. And its just a fraction of the size of the Sun.From our per
5、spective on Earth, the Sun looks very small. This is because its about 93 million miles away from us. The Suns diameter at its equator is about 100 times bigger than Earths, and about a million Earths could fit inside the Sun. TheSun is inconceivably, mind-bogglingly bigger.But without the Sun, the
6、Earth could not exist. In a sense, the Earth is a giant machine, full of moving parts and complex systems. All those systems need power, and that power comes from the Sun.The Sun is an enormous nuclear power source-through complex reactions, it transforms hydrogen into helium, releasing light and he
7、at. Because of these reactions, every square meter of our planets surface gets about 342 Watts of energy from the Sun every year. This is about 1.7 1017 Watts total, or as much as 1.7 billion large power plants could generate. You can learn about how the Sun creates energy in How the Sun Works.When
8、this energy reaches the Earth, it provides power for a variety of reactions, cycles and systems. It drives the circulation of the atmosphere and the oceans. It makes food for plants, which many people and animals eat. Life on Earth could not exist without the Sun, and the planet itself would not hav
9、e developed without it.To a casual observer, the Suns most visible contributions to life are light, heat and weather.Night and DaySome of the Suns biggest impacts on our planet are also its most obvious. As the Earth spins on its axis, parts of the planet are in the Sun while others are in the shade
10、. In other words, the Sun appears to rise and set. The parts of the world that are in daylight get warmer while the parts that are dark gradually lose the heat they absorbed during the day.You can get a sense of how much the Sun affects the Earths temperature by standing outside on a partly cloudy d
11、ay.When the Sun is behind a cloud, you feel noticeably cooler than when it isnt. The surface of our planet absorbs this heat from the Sun and emits it the same way that pavement continues to give off heat in the summer after the Sun goes down. Ouratmosphere does the same thing-it absorbs the heat th
12、at the ground emits and sends some of it back to the Earth.The Earths relationship with the Sun also creates seasons. The Earths axis tips a little-about 23.5 degrees. One hemisphere points toward the Sun as the other points away. The hemisphere that points toward the Sun is warmer and gets more lig
13、ht-its summer there, and in the other hemisphere its winter. This effect is less dramatic near the equator than at the poles, since the equator receives about the same amount of sunlight all year. The poles, on the other hand, receive no sunlight at all during their winter months, which is part of t
14、he reason why theyre frozen.Most people are so used to the differences between night and day (or summer and winter) that they take them for granted.But these changes in light and temperature have an enormous impact on other systems on our planet. One is the circulation of air through our atmosphere.
15、 For example:The Sun shines brightly over the equator. The air gets very warm because the equator faces the Sun directly and because the ozone layer is thinner there.As the air warms, it begins to rise, creating a low pressure system. The higher it rises, the more the air cools. Water condenses as t
16、he air cools, creating clouds and rainfall. The air dries out as the rain falls. The result is warm, dry air, relatively high in our atmosphere.Because of the lower air pressure, air rushes toward the equator from the north and south. As it warms, it rises, pushing the dry air away to the north and
17、the south.The dry air sinks as it cools, creating high-pressure areas and deserts to the north and south of the equator.This is just one piece of how the Sun circulates air around the world-ocean currents, weather patterns and other factors also play a part. But in general, air moves from high-press
18、ure to low-pressure areas, much the way that high-pressure air rushes from the mouth of an inflated balloon when you let go. Heat also generally moves from the warmer equator to the cooler poles.Imagine a warm drink sitting on your desk-the air around the drink gets warmer as the drink gets colder.
19、This happens on Earth on an enormous scale.The Coriolis Effect, a product of the Earths rotation, affects this system as well. It causes large weather systems, like hurricanes, to rotate. It helps create westward-running trade winds near the equator and eastward-running jet streams in the northem an
20、d southem hemispheres. These wind patterns move moisture and air from one place to another, creating weather patterns. (The Coriolis Effect works on a large scale-it doesnt really affect the water draining from the sink like some people suppose. )The Sun gets much of the credit for creating both win
21、d and rain. When the Sun warms air in a specific location, that air rises, creating an area of low pressure. More air rushes in from surrounding areas to fill the void, creating wind. Without the Sun, there wouldnt be wind. There also might not be breathable air at all.Water and FireThe Sun has a hu
22、ge effecton our water. It warms the oceans around the tropics, and its absence cools the water around the poles. Because of this, ocean currents move large amounts of warm and cold water, drastically affecting the weather andclimate around the world. The Sun also drives the water cycle, which moves
23、about 18,757 cubic miles (495,000 cubic kilometers) of water vapor through the atmosphere every year.If youve ever gotten out of a swimming pool on a hot day and realized a few minutes later that you were dry again, you have firsthand experience with evaporation. If youve seen water form on the side
24、 of a cold drink, youve seen condensation inaction. These are primary components of the water cycle, also called the hydrologic cycle, which exchanges moisture between bodies of water and land masses. The water cycle is responsible for clouds and rain as well as our supply of drinking water.注意：此部分试题

In some ways, however, very little has changed, particularly where attitudes are concerned. Ideas about social class-whether a person is working- class or middle-class-are one area in which changes have been extremely slow.In the past, the working-class tended to be paid less than middle-class people, such as teachers and doctors. As a result of this and also of the fact that workers jobs were generally much less se
