Some use them to keep a close watch on the demand for their line of work or gather information on compensation to arm themselves when negotiating for a raise.为什么or并列的是不定式to keep和(to)gather,而不能是use与gather并列呢?
The great development they made___(depend)on new technologies and their hard work.请问为什么是depends而不是depended?老师,您好!made是过去语态,难道统一有什么问题吗,个人觉得depends和depended在这里都可以,可以是强调客观事实对此评价也可...
