5B班的趣味地理课

In the past few weeks, we have been learning about latitude and longitude in geography class. We learned that the lines of latitude and longitude create a co-ordinate grid that we can use to find different places on earth.

过去几周里，我们在地理课上学习了经度和维度。我们发现经纬线交织在一起形成的网格可以帮助我们在地球上定位不同的地方。

Lines of latitude are the horizontal lines on the grid and each line of latitude is a measurement either North or South of the Equator. The Equator is the line of latitude that separates the northern and southern hemispheres. Lines of latitude are measured in degrees, the equator represents 0° (degrees) of latitude. The farther away from the equator you are, the greater the latitude. The North pole is 90° (degrees) North and the South pole is 90° (degrees) South of the equator.

纬线是网格中的横线，每条纬线可以来确定是在北部、南部还是赤道。赤道指的是将地球分成南北半球的那条线。纬线一般用度表示，赤道代表0度。离赤道越远，表示纬度越高。北极位于北纬90度，南极位于赤道以南90度。


Lines of longitude are the vertical lines on the grid. Each line of longitude is a measurement either East or West of the Prime Meridian. Lines of Longitude are also measured in degrees and the Prime meridian represents 0° degrees of longitude. The prime meridian also separates the eastern and western hemispheres. You can travel 180° East or 180° West of the prime meridian. This will bring you to the opposite side of the planet.

经度是网格中竖直的线。每条经线都是本初子午线以东或以西的一个量度。经线也是用度测量，本初子午线表示经度0度。本初子午线将地球分成东西两个半球，你如果向东或向西行180度，会将你带到地球的另一端。


The students found latitude and longitude interesting because we are using something that we have learned in math before, the co-ordinate grid, in the real world. We can use latitude and longitude co-ordinates to find places all over our planet. Students enjoyed finding the coordinates to some of their favorite places. Here are some examples:
Beijing - 40°N, 116°E
Dublin - 53°N, 6°W
New York - 40°N, 74°W
Sydney - 34°S, 151°E

学生们觉得经纬度非常有趣因为我们在使用之前数学上学的坐标格应用在了真实世界。我们可以使用经纬网在地球上找到任何一个地方。学生们很喜欢在经纬网上寻找他们最喜欢的地方。比如：

北京——北纬40°，东经116°
都柏林——北纬53°，西经6°
纽约——北纬40°，西经74°
悉尼——南纬34°，东经151°
