解析試題分析：考查將來(lái)時(shí)的表達(dá)法。Be to do sth表示將來(lái)時(shí)的時(shí)候，表示一種語(yǔ)氣，非要做某事，相當(dāng)于must，be sure to do sth；be about to do sth即將做某事，不與具體的將來(lái)時(shí)的時(shí)間狀語(yǔ)連用；be going to do sth表示計(jì)劃好要做某事，或者根據(jù)某種跡象要做某事；be due to do sth表示預(yù)定好了要做某事；句意：如果你一定要趕上早班公交車(chē)，務(wù)必要在5點(diǎn)之前就起床。故A正確。
