Question

【題目】—To save energy, we should _________ the electricity when we don't use it.—I agree, you are really a greener person.
A.shut up
B.shut off
C.take away
D.take off

Answer 1

【答案】B
【解析】句意：——為了節(jié)約能源，我們應(yīng)該不用電的時候，關(guān)掉電源�！�—我同意，你真是一個綠色環(huán)保的人。shut up閉嘴；shut off關(guān)掉；take away拿走；take off脫下。根據(jù)when we don't use it可知不用電的時候，應(yīng)關(guān)掉電源。故選B。
