: 想請教我的觀念與排除答案方法對不對



: 1.我先用時態排除,因為1967比1968早,因此時態上1967子句要用過去完成式
: 1968子句要用過去式,但是對等連接詞(and,but不用計較時態先後,需一致)
: =>排除(A)(B)(C)(E)

應該只能排除A吧? 對等連接詞前後時態沒有一定要一致。

: 2.脫節=>排除(B)

脫節可以刪除B/C

B選項student變成announced的邏輯主語，應該是the pulsar was observed這件
discovery才是announced的邏輯主語。

C選項discovery變成observed的邏輯主語，但是應該是pulasr做邏輯主語才合理

: 3.(A)裡面although裡子句缺動語態分詞=>排除(A)
看不太懂所謂的缺動詞語態分詞，在A選項although的主詞是pulsar，動詞是was，沒有
問題

: 4.while有對比與同時兩個意思,導致歧意=>排除(E)

這樣刪是有風險的，基本上這題可以，但是應該看搭配的選項是否有更直接清楚的修飾語

: 綜合以上,選擇(D)
: 請問這樣分析正確嗎?尤其是時態排除法部分
: 謝謝
