Question

9．学生们看上去很疲劳，因为他们既要努力学习又要为体测做准备．
The students look very tired because they have tonot only study hard but also get ready for the PE test．

Answer 1

分析 not only study hard but also get ready for．

解答 答案：not only study hard but also get ready for．表示既要…又要…用not only…but also…连接两个对等成分，have to表示不得不，后加动词原形，故这里是用not only…but also…连接两个动词短语，努力学习study hard，为…做准备，结合后面的the PE test名词短语用get ready for表示为…做准备，故答案是not only study hard but also get ready for．

点评 not only…but also…表达的意思是"不但…而且…"，注意以下用法：
■主要用于连接两个对等的成分；若连接两个成分作主语，其后谓语动词与靠近的主语保持一致．如：
She likes not only music but also sport．她不但喜欢音乐而且喜欢运动．
The place was not only cold，but also damp．那个地方不但很冷而且很潮湿．
We go there not only in winter，but also in summer．我们不仅冬天去那儿，而且夏天也去．
Not only the students but also their teacher is enjoying the film．不仅学生们在欣赏这部影片，他们的老师也在欣赏这部影片．
