Question

—________ the population of the U.S.A. in 2005?
—It ______ about 296 million.
A. What is; is             B. What was; was          C. How many was; was

Answer 1

B

解析試題分析：句意：2005年美國(guó)人口是多少？大約296 million。對(duì)population提問(wèn)常用What，時(shí)間是2005，所以用一般過(guò)去時(shí)。population相當(dāng)于一個(gè)整體,謂語(yǔ)是但是，所以用was。故選B。
考點(diǎn): 考查疑問(wèn)詞和動(dòng)詞時(shí)態(tài)的用法。
