--- Whom shall I give the document?
--- To ______ is in the office. However, ______ to require a written paper for it.

A． whom; make sure	B． who; make sure
C． whomever; be sure	D． whoever; be sure

答案

D

解析

“我应该把文件给谁？”“谁在办公室就给谁。然而，要保证是用信纸写的。”句子缺少主语，故用who/whoever，排除A、C；make sure后常加that从句。be sure to do sth.“确保......”。故选D。
