※ 引述《Diablotin (咕嚕咕嚕)》之銘言：
: Paragraph 5: The Jovian planets have very thick atmospheres consisting of
: varying amounts of hydrogen, helium, methane, and ammonia. By comparison,
: the terrestrial planets have [meager] atmospheres at best. A planet's ability
: to retain an atmosphere depends on its temperature and mass. Simply stated,
: a gas molecule can evaporate from a planet if it reaches a speed known as
: the escape velocity. For Earth, this velocity is 11 kilometers per second.
: Any material, including a rocket, must reach this speed before it can leave
: Earth and go into space. The Jovian planets, because of their greater masses
: and thus higher surface gravities, have higher escape velocities (21-60
: kilometers per second) than the terrestrial planets. Consequently, it is more
: difficult for gases to "evaporate" from them. Also, because the molecular
: motion of a gas depends on temperature, at the low temperatures of the Jovian
: planets even the lightest gases are unlikely to acquire the speed needed to
: escape. On the other hand, a comparatively warm body with a small surface
: gravity, like Earth's moon, is unable to hold even the heaviest gas and thus
: lacks an atmosphere. The slightly larger terrestrial planets Earth, Venus,
: and Mars retain some heavy gases like carbon dioxide, but even their
: atmospheres make up only an infinitesimally small portion of their total mass.
: 5. The word [meager] in the passage is closest in meaning to
: ○over time
: ○long ago
: ○simply
: ○certainly
: 答案是B 不懂怎麼選的耶......
: 又要請戰友們幫忙了 快考試啦～好緊張
只要看前兩句就可以了
我找到的TPO 選項不一樣耶
有些寫
○rich
○thin
○unique
○complex
所以是B
但是黃金閱讀7
○over time
○long ago
○simply
○certainly
也選B 就奇怪了
The Jovian planets have very thick atmospheres consisting of
varying amounts of hydrogen, helium, methane, and ammonia.
By comparison,the terrestrial planets have [meager] atmospheres at best.
重點應該是
Jp thick , varying amounts
<>
tp
<>相反 因為文章有寫 By comparison,相較之下
而且句尾at best (充其量)
所以我推斷這是相反的意思 應該是 thin
所以後面的選項應該有問題
並不是long ago,也不是simply(這是個副詞)
我覺得可能這題的題目不完整 或有出錯
