问题     “神舟九号”载人飞船即将从酒泉卫星发射中心发射升空,而气象保障在航天发射活动中发挥着举足轻重的作用。
    在酒泉卫星发射中心载人航天发射场的气象台,操作人员正在调试为这次“神九”载人飞船发射任务最新装备的高空电场传感器。
    这种高空电场传感器随高空探测气球一起升空,传感器上的发射机将探测到的电场强度、经纬度、海拔高度等数据发回到地面的计算机里,供气象人员分析、判断是否符合发射的条件。
    飞船发射时温度要求在零下二十度至零上四十度之间,湿度不能大于95%,不能下雨雪,更不能有雷电。

选项

答案 The Shenzhou-9 manned spacecraft is about to blast off from the Jiuquan Satellite Launch Center, and in this process meteorological support plays a decisive role. At the observatory of Launch site for manned space flight in Jiuquan Satellite Launch Center, operators are busy testing and debugging the latest high-altitude electric field sensor equipped for this space mission. Carried by a sounding balloon, this sensor will rise into the air, and its transmitter will send the data, including the electric field intensity, longitude, latitude and altitude, back to the computer at the observatory for the meteorologists to analyze and decide whether the weather conditions for the launch are met. Upon the spacecraft launches, the temperature is required to be in a range of minus 20 degrees to 40 degrees and the humidity is expected to be lower than 95%. There can be no rain or snow, and certainly there can be no thunder or lightning.

解析     “发射升空”使用表主动的动词词组blast off,意思是“点火起飞,发射升空”,与之后使用的表示发射的动词launch意思相同,使用多样词汇,增加了用词的丰富度。“发挥着举足轻重的作用”可以用play a decisive role来表达,decisive有“关键性的,决定性的”的意思。
    “‘神九’载人飞船发射任务”在上句中已经出现,为使表述简洁,用this space mission来指代。“高空”对应英文中的high-altitude。
