这样回答可以吗？第二点不知道是否成立，麻烦老师看看。

1.repurchase agreements is close-end, it usually short-term and has maturity, securities lending is open-end, and do not has maturity.

这句能感觉是想说：Repo有特定的时间期限，及到期日，Securities lending往往不会有特定的到期日。

这个回答OK。

2. repurchase agreements usually has requirment of the collateralized security, while securities lending do not.

后面while securities lending do not有点问题，两个策略都有抵押物。Repo的抵押物就是债券；Securities lending的抵押物可以是cash，也可以是债券
