1. It is called a sea, but the landlocked Caspian is actually the largest lake on Earth, which covers more than four times the surface area of its closest rival in size, North America’s Lake Superior.
(A) It is called a sea, but the landlocked Caspian is actually the largest lake on Earth, which covers
(B) Although it is called a sea, actually the landlocked Caspian is the largest lake on Earth, which covers
(C) Though called a sea, the landlocked Caspian is actually the largest lake on Earth, covering
(D) Though called a sea but it actually is the largest lake on Earth, the landlocked Caspian covers
(E) Despite being called a sea, the largest lake on Earth is actually the landlocked Caspian, covering
答案解析如下：
(A)It is called a sea, but the landlocked Caspian is actually the largest lake on Earth, which covers
【錯誤】 修飾成分：定語從句“which covers……”本意上修飾“the largest lake”或“Caspian”，因此構成了跳躍修飾(與“which”就近的是“Earth”)，正確選項應儘量避免跳躍修飾，因此本選項遜於(C)——“，covering”是“is actually the largest lake”
的伴隨狀語(只有針對定語才討論是否存在跳躍修飾的問題)，與其同(邏輯)主語“Caspian”。
(B)Although it is called a sea, actually the landlocked Caspian is the largest lake on Earth, which covers
【錯誤】 修飾成分：類似地，見(A)。
(C)Though called a sea, the landlocked Caspian is actually the largest lake on Earth, covering
【正確】 “Though called a sea” 屬於從句省略，根據從句省略的語法要求，被“called a sea”的是主句的主語“landlocked Caspian”，表意合理。“covering……”是“is actually the largest lake on Earth”的伴隨狀語，兩者(邏輯)主語同為“landlocked Caspian”，表意合理。
【大意】 儘管被稱作海，內陸湖裡海實際上是地球上最大的湖，覆蓋面積是僅次之的北美五大湖之Superior湖的.四倍。
(D)Though called a sea but it actually is the largest lake on Earth, the landlocked Caspian covers
【錯誤】 句子結構：“though”和“but”，在一對轉折關係中只用其一，不得同時使用。
(E)Despite being called a sea, the largest lake on Earth is actually the landlocked Caspian, covering
【錯誤1】 句子意思：“Despite being called a sea, the largest lake on Earth is actually the landlocked Caspian”中“被稱作海”與“地球上最大的內陸湖是裡海”是一對轉折關係，但這種轉折關係並不合理。
【錯誤2】 簡潔明瞭：動名詞“being”在GMAT考察的標準書面英語中不具有簡潔性。
【最優解題思路推薦】
“though”和“but”不應放在同一個轉折關係裡，立即排除(D)。
(A)、(B)存在正確選項應儘量避免的結構——跳躍修飾，(E)中“being”不具有簡潔性，因此選擇(C)。
