Question

—Computer is so useful. It can do almost everything.
—Yes, but it ______ what to do.

A．will tell

B．has known

C．must be told

D．is told

Answer 1

C

試題分析：根據(jù)語(yǔ)境可知此句的含義是電腦很有用,它幾乎能做任何事情,但它必須被告訴做什么.因主語(yǔ)是it,是動(dòng)詞的承受者,故用被動(dòng)語(yǔ)態(tài),根據(jù)語(yǔ)氣可知要用含有情態(tài)動(dòng)詞的故用C.
點(diǎn)評(píng)：含有情態(tài)動(dòng)詞的被動(dòng)語(yǔ)態(tài)，其結(jié)構(gòu)為“情態(tài)動(dòng)詞can/could/may/might/should/will
/shall/would/need等+助動(dòng)詞be+及物動(dòng)詞的過去分詞”
