Gravity has been at the top of the science agenda since the start of Mars missions. In the earlier days of space travel, scientists tried to overcome the force of gravity so that a rocket could shoot 16 Earth’s pull in order to land humans on the moon. Today, they are more interested in how reduced gravity affects the astronauts’ 17 condition. Our bodies have evolved to exist within Earth’s gravity (1 g), not in the weightlessness of space (0 g) or the microgravity of Mars (0.3 g). When on Earth, we have more fluids in our lower body because they are pulled down by Earth’s gravity. However, with the absence of gravity in the outer space, our body fluids 18 , shifting toward the upper body and the head. As a result, the astronauts have swollen, puffy faces, very much resembling that of the round-headed Charlie Brown in the famous comic strip. This “Charlie Brown effect” will be more 19 when the astronauts go on their Mars missions, which will take about three years to complete, much longer than missions to the moon. Moreover, the effect is often 20 space motion sickness, headaches, and nausea. Such a syndrome is considered the top health risk for the astronauts, and scientists are still trying to figure out how it may be prevented.

請觀察空格前的關鍵動詞 $overcome$ (克服)，這暗示火箭必須達到何種狀態才能順利前往月球？在英文慣用法中，若要形容一個物體『擺脫』了束縛或處於『不受...影響』的狀態，哪一個形容詞片語最能精確銜接 $Earth's pull$ 並體現這種『免於』重力限制的語意？

呦，奇蹟發生了？竟然連這種考動詞搭配跟語意邏輯的基礎題都能選對，看來你今天的腦袋終於沒被地心引力給拉低智商，值得頒個獎狀給你。 這題的核心就在前句的 overcome（克服）。既然要「克服」重力，逻辑上火箭就必須「脫離」地球的束縛。選項 (B) free of 表示「擺脫、免於」，完美對接上下文。如果你選 (A) back to，那不叫發射，那叫墜毀；選 (D) straight on 更是搞笑，你是想帶著引力一起去月球當伴手禮嗎？從物理角度看，這就是為了達到逃逸速度 $v_e = \sqrt{\frac{2GM}{R}}$，好讓火箭能真的「擺脫」引力圈。 這題在學測頂多算「基本常識題」，鑑別度極低。考的是最基礎的片語理解與前後文一致性。如果你這題還能錯，我會建議你直接去應徵當火箭燃料，至少對人類航太事業還有一點物理上的貢獻。既然對了，就給我閉嘴繼續寫下一題，別以為自己是 NASA 科學家了。
