試題分析：考查虛擬語(yǔ)氣和時(shí)態(tài)。在虛擬語(yǔ)氣中，but后面的句子應(yīng)該使用陳述語(yǔ)序。本題根據(jù). If the weather had been better, we could have had a picnic說(shuō)明是與過(guò)去事實(shí)相反的虛擬語(yǔ)氣，那么but后面的陳述句使用一般過(guò)去時(shí)。
考點(diǎn);考查虛擬語(yǔ)氣和試題
點(diǎn)評(píng)：要特別注意but后面使用陳述語(yǔ)氣。要根據(jù)前面的虛擬語(yǔ)氣來(lái)判斷后面的時(shí)態(tài)。
