三、單項(xiàng)選擇。

1.Thisismy,andthesearehis.

A.dogs；dogsB.dog；dogC.dog；dogsD.dogs；dog

【答案】C

【解析】句意：這是我的狗，這些是他的狗。

考查名詞。根據(jù)“Thisis”可知，第一空應(yīng)用單數(shù)名詞；根據(jù)“theseare”可知，第二空用復(fù)數(shù)名詞，故選C。

2.Thereanappleandthreeonthetable.

A.are,glassofwaterB.is,glassesofwater

C.are,glassesofwaterD.is,glassofwater

【答案】B

【解析】句意：桌子上有一個(gè)蘋果和三杯水。

考查主謂一致和不可數(shù)名詞的表達(dá)。therebe句型中，be動(dòng)詞形式與最接近的名詞一致，應(yīng)與“an

apple”一致，用is；water是不可數(shù)名詞，表達(dá)數(shù)量應(yīng)用量詞，空前有“three”修飾，glass用復(fù)數(shù)形式，而wat

er不能加s,應(yīng)表達(dá)為threeglassesofwater,故選B。

3.—Whafsonthetable?

-Thereisalotofonit.Ilikeeatingitverymuch.

A.booksB.orangeC.breadD.vegetables

【答案】C

【解析】句意：——桌子上有什么？——有很多面包，我非常喜歡吃。

考查名詞辨析和不可數(shù)名詞。books書；orange橙汁；bread面包；vegetables蔬菜。There

is...“有"，主語(yǔ)應(yīng)該是單數(shù)或不可數(shù)名詞，排除A和D；根據(jù)“Ilikeeatingitvery

much”，B選項(xiàng)是飲料，不是吃的。故選C。

4.TomandTimhavesomeand.

A.tomatos;chickenB.tomatoes;chickensC.tomatoes;chickenD.tomatos;chickens

【答案】C

【解析】句意：湯姆和蒂姆吃了一些西紅柿和雞肉。

考查可數(shù)名詞復(fù)數(shù)和不可數(shù)名詞。tomato表示“西紅柿”，其復(fù)數(shù)形式為tomatoes；chicken表示“雞肉”時(shí)，

是不可數(shù)名詞，表示“小雞”時(shí)，是可數(shù)名詞。根據(jù)“TomandTimhavesome...”可知此處是指雞肉，故選C。

A.sport;shoesB.sports;shoesC.sport;shoeD.sports;shoe

【答案】D

【解析】句意：離我的學(xué)校不遠(yuǎn)有一家體育用品店和兩家鞋店。

考查名詞的用法。sport運(yùn)動(dòng)，復(fù)數(shù)形式為sports；shoe鞋，復(fù)數(shù)形式為shoes。sports

shop“體育用品商店”，固定短語(yǔ)；shoe

shop“鞋店”，shoe是名詞做定語(yǔ)，故用單數(shù)形式，變復(fù)數(shù)時(shí)，只需要shop變復(fù)數(shù)，shoe不變。故選D。

6.一DidyouwatchTVathomelastSunday?

-No,Ifedsomeatmygrandma'shome.

A.cowB.sheepC.chickenD.dog

【答案】B

考查名詞辨析。cow奶牛；sheep羊；chicken雞；dog狗?？涨懊嬗衧ome修飾，后面如果是接可數(shù)名詞應(yīng)該

用其復(fù)數(shù)形式。只有B選項(xiàng)sheep單復(fù)數(shù)形式相同，cow、chicken和dog都是單數(shù)。故選B。

7.一Mom,Iamhungry.MayIhavesome.

一Ofcourse.Butdon'teattoomuch.

A.breadB.noodleC.dumplingD.hamburger

【答案】A

【解析】句意：一媽媽，我餓了。我可以吃點(diǎn)面包嗎？一當(dāng)然。但是不要吃太多。

考查可數(shù)名詞和不可數(shù)名詞。bread面包；noodle面條；dumpling餃子；hamburger漢堡包。根據(jù)"some”可

知，此空需要一個(gè)不可數(shù)名詞或者可數(shù)名詞復(fù)數(shù)，結(jié)合選項(xiàng)，BCD均是可數(shù)名詞單數(shù)形式，因此“bread”

符合句意。故選A。

8.Thereis（有）much______intheplate（盤子）.

A.bananaB.appleC.pearsD.chicken

【答案】D

【解析】句意：盤子里有許多雞肉。

考查名詞辨析。banana香蕉，可數(shù)名詞單數(shù)；apple蘋果，可數(shù)名詞單數(shù)；pears梨，可數(shù)名詞復(fù)數(shù)；chicke

n雞肉，不可數(shù)名詞，根據(jù)空前的"much”修飾不可數(shù)名詞可知，應(yīng)該用chicken,故選D。

9.Letmeshowyousomeofsome.

A.photos,tomatoesB.photoes,tomatosC.photos,tomatosD.photoes,tomatoes

【答案】A

【解析】句意：讓我給你看一些西紅柿的照片。

考查名詞復(fù)數(shù)形式。photo是無(wú)生命的以o為結(jié)尾的名詞，變復(fù)數(shù)直接加s。tomato是有生命的以o為結(jié)尾的

名詞，變復(fù)數(shù)直接加es,故選A。

10.Wehavemuchtodoeveryday.

A.workB.jobC.jobsD.works

【答案】A

【解析】句意：我們沒(méi)太有太多的工作要做。

考查名詞辨析。job和work都有“工作”的意思，job是可數(shù)名詞，復(fù)數(shù)是jobs；work是不可數(shù)名詞?？崭袂?/p>

面的much修飾不可數(shù)名詞。故選A。

11KateandAliceareinthesame,buttheyareindifferent.

A.grade；classB.grade；classesC.grades；classD.grades；classes

名詞；pears梨，可數(shù)名詞的復(fù)數(shù)形式。how

詞，有復(fù)數(shù)形式，yuan沒(méi)有復(fù)數(shù)形式，此處應(yīng)該說(shuō)80doilars,排除選項(xiàng)A。故選C。
