1.        Unlike transplants between identical twins, whose genetic endowment is the same, all patients receiving hearts or other organs must take antirejection drugs for the rest of their lives.

(A) Unlike transplants between identical twins, whose genetic endowment is the same

(B) Besides transplants involving identical twins with the same genetic endowment

(C) Unless the transplant involves identical twins who have the same genetic endowment

(D) Aside from a transplant between identical twins with the same genetic endowment（C）

(E) Other than transplants between identical twins, whose genetic endowment is the same

这题说因为D,E都用a transplant和后面的patient比较，所以不对。

1.        With diamonds, as with all gems, one should ask for a written description of one’s purchase; the description may prove useful later if you have reason to believe the jeweler misled you.

(A) one should ask for a written description of one’s purchase

(B) you should ask for a written description of your purchase

(C) a written discretion of your purchase is what one should ask for

(D) a written description of one’s purchase is what should be asked for（B）

(E) a written description of your purchase is what should be asked for

所以做这题的时候，我居然想到了上面的话，于是认为是否B用diamond和you比较，所以不对，很犹豫。

语法基础不好，请帮解释一下有什么不同，这两个题的考点是什么？谢谢！

with和like,unlike是不一样的，后两词才要求逻辑一致。
