Cells grow and develop，reproduce and interact with the environment。 这句话中with the environment 是跟interact搭配，那and前是个动词reproduce，后面是动宾，这样的and前后是并列成分吗？ The people who hire and director the work of other employees are managers。这句话hire和direct是并列的，为什么hire不是修辞 the work of other employees而只是修饰employeess呢？ Benefits include vacation time,health insurance and bonuses for employees who do a good job. 这里的for employees who do a good job是修饰vacation time，health insurance and bonuses还是只修饰bonuses? 写的有点多，但都是同一个问题，望老师通过并解惑，谢谢！
