在逻辑意思都对时,to do比for doing更好,但两者都对 但此句中,discovery不是人,发不出表目的的to do,只有for doing合理
discovery to determine, discovery 不能发出动作表目的的to do 文章意思: discovery 提供了clues for doing sth (Provide sth for doing sth ... when and how 搭配明确,简介) in the determination: 不简洁 to determine.. how they did : for determining when ... and how they were : WORDY for determining how and when... CORRECT
特定對象邏輯主語可用for Ving for determining的邏輯主語是scientists clue的用法: clue for/to
how and when 更优越; 修饰clue
provide for doing how and when 句子很简洁。
provide sth for sb provide sb with sth
动词优于名词,provide sth for。。。
在逻辑意思都对时,to do比for doing更好,但两者都对 但此句中,discovery不是人,发不出表目的的to do,只有for doing合理
provide sth for doing
注意C选项中末尾的they指代不明确
provide sth for sb。。。。provide sth1 to do sth2: 强调意图 provide sth1 for doing sth2: 强调the use of sth1。代词THEY,代词优先指代主句主语Scientists,发现不合逻辑,只有E,利用how and when平行避免了代词的使用
