【题目】北京时间(东八区)2017年4月22日12时23分,我国天舟一号和天宫二号顺利完成自动交会对接。完成下面小题。

1居住在英国伦敦的华人华侨收看了卫星发射实况转播,完成自动交会对接时,伦敦时间(零时区)为

A. 4月22日12时23分 B. 4月22日0时23分

C. 4月22日8时23分 D. 4月22日4时23分

2造成两地时间不同的原因是

A. 地球是个两极略扁的椭球体 B. 地球绕太阳公转

C. 地球的自转 D. 地球是静止不动的

【答案】

1 D

2 C

【解析】

(1)理解“东加西减”,推算区时。已知西侧时区的区时,求东侧时区的区时,要用加法,即“东加”;已知东侧时区的区时,求西侧时区的区时,要用减法,即“西减”。

(2)地球绕着地轴不停地旋转叫地球自转,地球自转的方向为自西向东,地球自转产生的地理现象是昼夜交替和时间差异。

1北京在东八区,伦敦在零时区,相差八个时区,即八个小时。北京时间(东八区)20174221223分时,居住在英国伦敦的华人华侨收看了卫星发射实况转播,完成自动交会对接时,伦敦时间(零时区)为422423分。故选D。

2地球绕着地轴不停地自西向东旋转叫地球自转,地球自转产生产生时间差异现象,也就是两地时间不同。故选C。

考查地球自转产生的地理现象及时差的计算。

【题目】Mr. Weeks is fifty years old. He's taught maths in a middle school for twenty years. He works hard and always comes to his office on time. He hopes his students will be honest and he is strict with them. Some of his students have become famous persons,but they still remember him and often write to him. Of course the man is proud of them.

This term he began to teach Grade One. Some of the new students were told about him, but the others didn't know about him. On the first day of school he told the students how to be an honest person. He gave them some examples and said, “I don't like telling a lie.” Before class was over, he told all his students to finish Exercise 8 in Lesson 1.

The next morning, as soon as he came into the classroom, he asked, “Who's finished Exercise 8?” A few students raised their hands. He shook his head and said, “Open your workbooks and see if there's Exercise 8 in Lesson 1. ”

The students had a look at their workbooks and their faces turned red at once.
