Answer 1

C

試題分析：根據(jù)回答，不知道，我認(rèn)為大約花費(fèi)了他4000元。賓語(yǔ)從句的結(jié)構(gòu)：主語(yǔ)+謂語(yǔ)+連接詞+從句。從句在句中作賓語(yǔ)。從句要用陳述句的語(yǔ)序。如果主句是一般現(xiàn)在時(shí)，從句根據(jù)需要選擇時(shí)態(tài)，如果主句是過(guò)去時(shí)態(tài)，從句要用相應(yīng)的過(guò)去時(shí)態(tài)。但是從句是客觀真理，一般用一般現(xiàn)在時(shí)態(tài)。根據(jù)句意，可知用過(guò)去時(shí)態(tài)，問(wèn)價(jià)錢，故選C。
