Question

We are confident that the environment ________ by our further efforts to reduce pollution.

A．improves

B．will be improved

C．has improved

D．was improved

Answer 1

B

試題分析：句意：我們確信經(jīng)過(guò)我們減少污染的進(jìn)一步努力，環(huán)境會(huì)被改善的。根據(jù)are confident我們現(xiàn)在確信， by our further efforts通過(guò)進(jìn)步的努力，那環(huán)境的改善應(yīng)是在將來(lái)，又因 主語(yǔ)environment 與謂語(yǔ)improve之間是被動(dòng)關(guān)系，故用一般將來(lái)時(shí)的被動(dòng)式。故選B。
