5. As the years passed, many occasions—birthdays, awards, graduations — ______ with Dad’s flowers. (2007湖南卷)

A. are marked                            B. were marked

C. have marked                          D. had marked

【解析】B。由于句中增加了插入成分birthdays, awards, graduations，使得句子的主語與謂語were marked分離，從而增加了考生對句子理解的難度。根據(jù)句意，空格處應(yīng)填被動語態(tài)；再根據(jù)句中的passed的時(shí)態(tài)特點(diǎn)可知，空格處也應(yīng)用一般過去時(shí)，故選B。
