"New York City is not America." That’s what kind American friends are sure to tell you when you arrive. "You must see Boston, visit Niagara Falls, go to Virginia, fly down to Florida, and so on; but first, of course, you will want to see New York. It is not the capital city of the United States (that is Washington, D. C., where the President lives) or even the capital city of New York State (that is Albany), but many people call it `the greatest city on earth’".
The five parts, or boroughs, of New York City are Manhattan, Queens, Bronz, Richmond and Brooklyn. Although Manhattan is not all of New York, it is the heart of the city. It is an island, which is only about 13 miles long and 2 miles wide. From the air its shape looks like a long finger, and from the sea it’s just like the picture we all know. Those tall, straight buildings - the skyscrapers - packed so close together on that island of rock are sometimes seen in the distance through a veil of early morning mist. You have imagined it so often that now it’s difficult to believe this beautiful sight is real, and unless your heart is as hard as stone, excitement will make it beat a little faster. Perhaps "greatest", "tallest", "longest", "biggest", "brightest", are the words you will find most often in the city guide books.

A heat pump is a single electric system (系统，制度) that both heats and cools. In summer, a heat pump is a conventional (普通的，习惯的) air conditioner which removes heat from a building. In winter, the system reverses itself to use the natural heat that is always present in outdoor air. By taking advantage of the free heat, a heat pump is more economical (节约的) to operate in winter than a system using electric resistance (阻力，抵抗，电阻) heat. Electric resistance heat uses electricity as a raw (生的，天然的) material to create (创造，产生) heat where no heat existed before. Heat pump, on the other hand, uses electricity to move existing heat from where it already exists naturally (outdoors) to where it is wanted (indoors (在室内)).
Heat energy will naturally flow from areas of greater concentration to areas of lesser (较少的，次要的) concentration. That is what happens when hot food grows cool. The heat from the food flows into the air in the room until the food stabilizes at room temperature. Blowing air over substance (物质，本质，主要部分) will speed up the process (过程，工序，诉讼，加工), which is why a winter day will seem cold when there is a strong wind than when the air is still.
A heat pump uses this heat transfer (转移，转让，改乘) process to move heat which is always in the air. The outdoor coil (线圈，卷) is made colder than the outdoors air. A fan blows outdoor air across the coil where heat is absorbed by the refrigerant (冷却剂). The refrigerant is then compressed and moved to the indoor coil and the heat is distributed in the building.
During the summer, a heat pump reverses this process. The indoor coil is made cooler than the indoor air, and so room heat flows into the refrigerant which is compressed and moved to the outdoor coil. The outdoor coil, which is hotter than the outdoor air, will lose heat energy.
