1。wasn't he? 當陳述部分must表示“必須”時，疑問部分用mustn't當陳述部分must表示“有必要”時，疑問部分用needn't當must表示“一定”“想必”推測意義時，疑問部分不用must,而要根據陳述部分的不定式結構以及含義采用相應的動詞形式例如：You must be hungry,aren't you? 2。We should......otherwise3。cut......shorter （我也不是很確定，sorry）4。four times......length5。begin---begin with6。正確。以上為個人看法，僅供參考。注：好象不是初中的英語吧？
