问题
选择题
--- 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
答案:D
“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。
