【題目】Television is more than an electronic equipment; it _____ a powerful tool for communication.

A.was becomingB.has becomeC.had becomeD.will become

【答案】B

【解析】

考查時態(tài)。句意: 電視不僅僅是一種電子設備； 它已成為強大的交流工具。根據(jù)前文的is可知本句應該用現(xiàn)在時。根據(jù)句意，這里表達的是電視“已經(jīng)成為”強大的交流工具，是過去發(fā)生的事到現(xiàn)在造成的結果，所以用現(xiàn)在完成時，故選B項。
