【題目】In the past, few people knew that the earth_______ around the sun.

A. moved B. had moved

C. moves D. was moving

【答案】C

【解析】句意：在過(guò)去，幾乎沒(méi)有人知道地球圍繞太陽(yáng)轉(zhuǎn)。A. moved一般過(guò)去時(shí)；B. had moved過(guò)去完成時(shí)；C. moves一般現(xiàn)在時(shí)；D. was moving過(guò)去進(jìn)行時(shí)。此句是賓語(yǔ)從句，主句是一般過(guò)去時(shí)，從句如果是客觀真理，時(shí)態(tài)不受主句的影響，要用一般現(xiàn)在時(shí)態(tài)表示，故答案為C。
