young, safety ,故選B。12.What do you think of the environment here, Mr. Wang?Wonderful! of the land covered with trees and grass.A.Two fifths。 is B.Two fifth。 is C.Two fifths。 are D.Two fifth。 are【答案】A【解析】句意:——你認為這里的環(huán)境怎么樣?——棒極了!五分之二的陸地被樹木和草所覆蓋。根據(jù)選項可知,第一個空所缺的詞為分數(shù);分數(shù)的表達法為分子基數(shù)詞,分母序數(shù)詞,分子大于1,分母加s,所以五分之二的表達方法為two fifths,排除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.Neither your sister nor mine the good news.

There ______ some milk, two eggs and a few cakes on the table.A.is B.a(chǎn)re C.has D.have【答案】A【解析】【詳解】句意:看!桌子上有一些牛奶,兩個雞蛋和一些蛋糕。本題考查There be句型的主謂一致。there be的主謂一致遵循的是就近原則,離be最近的some milk(不可數(shù)),所以用單數(shù)is,故選A。15.— your friend Tim have a new ipad?-No, he doesn’t, but I have one.A.Are B.Do C.Is D.Does【答案】D【解析】試題分析:句意:你的朋友提姆有一個新的iPad?-不,他沒有,但我有一個。謂語動詞have是一個實義動詞,主語your friend Tim屬第三人稱單數(shù),要構(gòu)成一般問句,需要助動詞does幫助。所以選D??键c:考查助動詞。16.Neither Amy nor her parents ______ to Australia, but _______ of them know Australian customs very well.A.have been, all B.have been, both C.has been, neither D.has been, none【答案】B【解析】句意:艾米和她的父母都沒去過澳大利亞,但他們都很了解澳大利亞的風(fēng)俗習(xí)慣。考查動詞時態(tài)和不定代詞辨析題。Neither A nor B,表示兩者都沒有/都不,遵循就近原則;空格前面的parents(父母)是復(fù)數(shù)形式,不可用has,可排除CD兩項。all全都;both兩者都,Amy和her parents是兩個方面,需用both。根據(jù)句意語境,可知選B。17.There ____ two concerts tomorrow evening.A.will are B.a(chǎn)re going to beC.is going to be D.a(chǎn)re going to have【答案】B【解析】試題分析:句意:明
