I am used to traveling by air.(改为否定句)I am not used to traveling by air.They haven’t decided yet.(改为同义句)=They have no decision.=They don't have any decision.祝你开心如意!那么第二题还有其他改法吗？原题是：They are 。再问一题：He urged me to accept a bottle of wine .(改为同义句) He a bottle of wine。可以变为They are with no decision.He urged me to accept a bottle of wine .(改为同义句) = He 【gave /offered me】 a bottle of wine。
