Prices____ all the time and no one knows when they         stable.
A．a(chǎn)re going up; becomeB．have been going up; will become
C．have gone up; will becomeD．have been gone up; become
B
考察時(shí)態(tài)。根據(jù)all the time一直可知第一空應(yīng)該使用現(xiàn)在完成進(jìn)行時(shí)。第二空是賓語(yǔ)從句，根據(jù)句意可知是將來(lái)時(shí)。句意：物價(jià)一直都在上漲。沒(méi)有人知道什么時(shí)候會(huì)穩(wěn)定下來(lái)。故B正確。
