    【题目】北京时间2011年11月3日1时36分6秒，“天宫一号”目标飞行器与“神舟八号”飞船成功实现首次会对接，右图是“神舟八号”与“天玄一号”首次对接空间位置示意图。读图回答下列各题。

    【1】

    A. ①线 B. ②线 C. ③线 D. ④线

    【2】

    A. 云雾 B. 流星 C. 太阳辐射 D. 太阳活动

    【答案】

    【1】A

    【2】C

    【解析】试题分析:

    【1】晨线与赤道的交点所在经线地方时为6点。当北京时间（东经120°经线的地方时）为1时36分6秒时，地方时为当天6时所在经线应该位于180°附近，所以A选项最合理。另②和④线与北极圈相切，应该表示的是12月22日左右的状况。

    【2】太阳活动强烈时，爆发的电磁波会引起电离层的扰动，引起无线电短波通信的中断，干扰航天器和地面指挥系统的通信联系，航天器和地面指挥系统联系主要靠无线短波进行，会受到太阳活动的干扰导致通讯衰减或中断。故C项正确。云雾、流星、太阳辐射均对通信没有影响。
