Question

8．課外活動不僅能幫助我們保持健康，而且還能增進友誼．
After-class activities cannot only help us keep healthy but also develop our friendship．

Answer 1

分析 not only help us keep healthy but also develop our friendship．

解答 答案：not only help us keep healthy but also develop our friendship．這里含有情態(tài)動詞can，后加動詞原形，表示不僅…而且…用not only…but also…，連接兩個對等成分，這里是連接兩個動詞短語原形，幫助某人做某事help sb do sth，保持健康keep healthy，故not only help us keep healthy but also，增進develop后加賓語我們的友誼our friendship，故答案是not only help us keep healthy but also develop our friendship．

點評 該表達的意思是"不但…而且…"主要用于連接兩個對等的成分；若連接兩個成分作主語，其后謂語動詞與靠近的主語保持一致．如：
She likes not only music but also sport．她不但喜歡音樂而且喜歡運動．．
Not only the students but also their teacher is enjoying the film．不僅學(xué)生們在欣賞這部影片，他們的老師也在欣賞這部影片．
