Man cannot live without air.
25、Can I go now? Yes, you can. could也可表示请求，语气委婉，主要用于疑问句，不可用于肯定句，答语应用can（即could不能用于现在时态的简略答语中）。如： Could I come to see you tomorrow? Yes, you can. （否定答语可用No, Im afraid not.） can表示能力时，还可用be able to代替。如： Ill not be able to come this afternoon. b. 表示惊异、怀疑、不相信的态度。（主要用在否定句、疑问句或惊叹句中） Can this be true? How can
