【題目】北京時(shí)間2011年11月3日1時(shí)36分6秒，“天宮一號”目標(biāo)飛行器與“神舟八號”飛船成功實(shí)現(xiàn)首次會對接，右圖是“神舟八號”與“天玄一號”首次對接空間位置示意圖。讀圖回答下列各題。

【1】

A. ①線 B. ②線 C. ③線 D. ④線

【2】

A. 云霧 B. 流星 C. 太陽輻射 D. 太陽活動

【答案】

【1】A

【2】C

【解析】試題分析:

【1】晨線與赤道的交點(diǎn)所在經(jīng)線地方時(shí)為6點(diǎn)。當(dāng)北京時(shí)間（東經(jīng)120°經(jīng)線的地方時(shí)）為1時(shí)36分6秒時(shí)，地方時(shí)為當(dāng)天6時(shí)所在經(jīng)線應(yīng)該位于180°附近，所以A選項(xiàng)最合理。另②和④線與北極圈相切，應(yīng)該表示的是12月22日左右的狀況。

【2】太陽活動強(qiáng)烈時(shí)，爆發(fā)的電磁波會引起電離層的擾動，引起無線電短波通信的中斷，干擾航天器和地面指揮系統(tǒng)的通信聯(lián)系，航天器和地面指揮系統(tǒng)聯(lián)系主要靠無線短波進(jìn)行，會受到太陽活動的干擾導(dǎo)致通訊衰減或中斷。故C項(xiàng)正確。云霧、流星、太陽輻射均對通信沒有影響。
