A．a(chǎn)re used; is	B．is being used; is
C．have been used; are	D．has been used; are

Answer 1

D

第一空考查主謂一致。means 方式，方法，單復(fù)數(shù)同形，主語是Every necessary means 每一種方法，謂語動詞應(yīng)用單數(shù)，deer也是單復(fù)數(shù)同形，在這里指復(fù)數(shù)所以謂語動詞用復(fù)數(shù)。句意：每一種必要的方法已經(jīng)被使用了來保護(hù)對我們來說非常有價(jià)值的麋鹿。結(jié)果，麋鹿的數(shù)量在增加。所以選D。
