Be ripe for sth：developed to a suitable condition for something to happen. （做某事的时机已成熟、已适合于）
例句：Sally and Sue were keen to translate their advertising and marketing skills into an online environment. To their surprise, they found that many websites seemed to have been developed without taking any account of users’ needs. Sure that the opportunity was ripe for a business with a strong marketing proposition, they started offering marketing services to other small online businesses.
例句2：She thinks the whole unemployment insurance system is ripe for an overhaul. （她认为整个失业保障体系是时候进行翻新和修整了。）
注：“Be ripe for”与”Be ready for”两个短语意思相仿，其不同之处在于：ripe强调的是时机上的成熟，而ready则强调的是条件上的具备。
