託福寫作中巧用分詞的3種方法
建議託福寫作目標衝7的考生，重點掌握分詞結構代替定語從句的用法。要寫出變化的句式，需在熟練掌握各種句型的同時，做到活學活用融匯貫通，並非易事。希望大家平時認真打好好語法和詞彙的基本功，多開口勤動筆，在實踐中學習。下面是小編給大家帶來的託福寫作中巧用分詞的3種方法，希望能幫到大家!
託福寫作怎麼慎用巧用分詞一：
用分詞替換定語從句時，分詞的邏輯主語就是定語從句前的先行詞。
如現在分詞：We stood on the bridge connecting the two halves of the building. (... the bridge which connects/connected the two halves...)前一句中的分詞connecting的邏輯主語是the bridge，和後一句中定語從句先行詞the bridge， 兩者一致。
試比較：The man who Tim is meeting for lunch is from Taiwan.此句的定語從句who Tim is meeting for lunch不可用分詞結構替換，即絕不能改成：The man Tim meeting for lunch is from Taiwan. 因爲分詞meeting的邏輯主語並不是定語從句先行詞the man，而是Tim，所以這是完全錯誤的說法。
又如過去分詞：The issue that club members are being asked to vote on at tonight’s meeting is that of a fee increase. 絕不可改成：The issue club members being asked to vote on at tonight’s meeting is that of a fee increase.分詞being asked的邏輯主語是club members，並不是定語從句先行詞the issue。
託福寫作怎麼慎用巧用分詞二：表因果
表因果，即當分詞所指行爲或事件引發了主句所指的事件或行爲，可以替換定語從句。
比較：A. The snow which fell overnight has turned to ice. (不可改爲The snow falling overnight...)只表先後，不表因果
B. The snow which fell overnight has caused traffic chaos. (可以用分詞The snow falling overnight has caused traffic chaos.)又先後，表因果。
託福寫作怎麼慎用巧用分詞三：用分詞時，不表動作先後，表伴隨狀態
用分詞時，不表動作先後，表伴隨狀態。如： The girl who fell over on the ice broke her arm. (不可改成The girl falling over on the ice broke her arm.)瞬間性行爲動詞fell over 和broke 有先後。 比較：I pulled off sheets which covered the furniture. 表狀態伴隨的動詞cover，替換成分詞ts covering the furniture.
託福寫作怎麼慎用巧用分詞四：情態動詞做謂語的定語從句，不可用分詞替換
情態動詞做謂語的定語從句，不可用分詞替換。如：There are a number of people who should be asked.
