l'll never forgive you ____ what you said last night.
A./ B.on C.to D.for
选 D.用 for 表原因.
Half of the class_____done most of the work.The left _____ rather difficult.
A.have,is B.has,is C.have,are D.has,are
选 A.“班上一半的学生”显然为复数,第一空用 have；“剩下的工作”显然为单数（因为work不可数）,故选 is.

forgive sb. for sth. 原谅某人(做了)某事(D)
考的是谓语单复数（A）

D.for
forgive for 原谅(某人)做了(某件错事)
A.have,is
half of the class意为全班半数同学，需接复数形式动词,强调个体成员时必须用复数的，后半句翻译为“剩下的活相当困难”，work不可数，要用单数
