【題目】They wonder ________ robots will make humans lose their jobs or not.

A. that B. if C. whether D. so

【答案】C

【解析】句意:他們想知道機器人是否會使人類失去工作?疾檫B詞辨析。A. that賓語從句引導(dǎo)詞,無實義;B. if是否,連詞;C. whether是否,連詞;D. so因此,連詞。本題是賓語從句,根據(jù)句意,可排除AD選項。ifwhether都可以引導(dǎo)賓語從句,但區(qū)別在于,當(dāng)句中有or(not)時,只能用whether而不可用if。故選C。
