问题 In the opening paragraph, the author introduces his topic by______.
The New Horizons will first approach Jupiter on its way to Pluto because______.
选项 A、Jupiter is a must station on the way to Pluto
B、Jupiter can help it get into its track to Pluto
C、Jupiter has the gravitational field
D、it is the fastest way
答案B
解析 事实细节题。新视野太空船之所以要先到达木星然后再到冥王星，其原因要从文中提到"木星"的地方寻找，第一段就提到"As it soared toward a 2007 meeting with Jupiter, whose powerful gravitational field will shoot it on its way to Pluto…"(它升空去和木星2007年约会，木星重力场会将其发射到去往冥王星的路上…)，从这里可以看出，之所以先到木星是为了利用其重力场转到去往冥王星的轨道上，因此选项"木星是去往冥王星的必经之站"；"木星可以帮助它进入到冥王星的轨道"；"木星有重力场"；"这是最快的路径"中，最符合的是答案选项。选项"木星有重力场"有一定的迷惑性，但要注意其原因不是木星拥有重力场，而是其重力场可以帮助太空船进入轨道。
