【文章內(nèi)容簡介】
B,D;分數(shù)后面的名詞為land,又知land意為“陸地,土地”,為不可數(shù)名詞,根據(jù)主謂一致的原則,所以第二個空缺處應(yīng)用is,故答案選A。點睛:“分數(shù)或百分數(shù)+名詞”等作主語時,謂語動詞的單復(fù)數(shù)形式取決于名詞,如果是單數(shù)名詞或不可數(shù)名詞,則謂語動詞用單數(shù)形式;如果是可數(shù)名詞復(fù)數(shù),則謂語動詞用復(fù)數(shù)形式。如:Two fifths of the machines on display are new items. 展出的機器有五分之二是新產(chǎn)品。 70% of the meat has gone bad. 70%的肉都變質(zhì)了。13.
