【題目】讀經緯網地圖,回答問題:

(1)寫出下列四點的地理坐標A B C D
(2)A、B、C、D四點中,位于東半球的是 , 位于北半球的是
(3)A點在C點的方向,B點在A點的方向,A點在D點的方向.

【答案】
(1)40°W,20°N;40°W,70°N;0°,20°N;10°W,0°
(2)CD;ABC
(3)正西;正北;西北
【解析】讀圖分析可知:(1)依據經緯度的判讀,圖中A點的地理坐標是40°W,20°N; B點的地理坐標是40°W,70°N;C點的地理坐標是0°,20°N;D點的地理坐標是10°W,0°.(2)東西半球分界線是20°W和160°E組成的經線圈,20°W以東、160°E以西為東半球,20°W以西、160°E以東為西半球.南北半球的劃分是以0°緯線即赤道為界,赤道以北為北半球,以南為南半球.由此可判定,A、B、C、D四點中,位于東半球的是CD,位于北半球的是ABC.(3)在經緯網地圖上,用經緯網定方向,緯線指示東西方向,經線指示南北方向.可判定,A點在C點的正西方向,B點在A點的正北方向,A點在D點的西北方向.故答案為:(1)40°W,20°N;40°W,70°N;0°,20°N;10°W,0°;(2)CD;ABC;(3)正西;正北;西北.

【題目】New Technology Revolutionizes(變革) Learning

More and more people believe that technologies are great for learning. Today, such teaching tools as iPads are used in a lot of courses, including language, history and science.

Many teachers are supporters of using iPads in language learning. They say that students now have much more time for discussion in the classroom.Instead of spending valuable class time listening to texts or watching teaching videos, students can do this on their own and come to class prepared for discussion.

The teachers also say that iPads allow students to learn at their own pace. Some students might listen to a dialogue only once and understand it, so they can save time for doing other things. Other students, however, might need to listen to the same dialogue again and again to understand it. Using iPads is especially helpful to students who are learning a language at different paces.

The students who are using the new tool in some courses are also happy. They believe that using iPads is a more enjoyable way to learn (such as listening to stories and watching movies). The class has become much more interesting and creative.

There are other advantages for students. By using iPads, they can pay more attention to the material and learn more. Teaching notes are stored in their iPads and are easy to find .Some students spend more time studying now.“I can listen to my language material or watch teaching videos on the bus, instead of having to wait until I get home,” a studentspan> explained.

Many adults complain that technologies such as iPads are doing harm to students. They worry that students might use iPads to download teaching notes and use them to cheat during exams. Some believe that iPads may separate students from each other. If a student spends more time watching videos on an iPad, he will have fewer opportunities to have face-to-face communication with others.

However, technologies are already a part of most students’ day-to-day lives. As for cheating, teachers can ask students to hand in their iPads when they take exams. Education needs to make changes with the times as technology is playing an important part. We should look forward to a wonderful future when iPads and other technologies can add a lot to the classroom.
