1.According to a survey, four out of five women do housework at home, but only _________ of men would do it.

【答案】D
【详解】
考查数词。句意:根据调查显示,五分之四的女性在家做家务,但是只有五分之二的的男性会在家做家务。分数的表达方法为:分子用基数词,分母用序数词,分子大于“1”时,分母要加s,根据规则可知,五分之四的正确表达为four fifths,五分之二的正确表达方法为two fifths;结合空格前“but only”可知,男性在家做家务的数量比较少,所以应填五分之二。故选D。
2._____ of the land in that district _____ covered with trees and grasses.
A.Two-fifth; is B.Two-fifth; are C.Two-fifths; is D.Two-fifths; are
【答案】C
【详解】
考查分数表达法和主谓一致。句意:那个地区五分之二的土地被树木和草覆盖。首先看第一个空,涉及到英语中分数的表达方法,在英语中,分子用基数词表示,分母用序数词表示,如果分子大于1,分母则要用复数形式,题干中的五分之二的分子大于1,故分母应用复数形式,应填Two-fifths。再看第二个空,当分数修饰的名词在句中作主语时,谓语动词的单复数形式取决于分数所修饰的名词,即与名词保持一致。本题中分数所修饰的名词是land,意为“土地”,为不可数名词,故谓语动词应用单数is。故选C项。
3.There are ________ books in our library.
A.hundreds of B.hundred of C.five hundreds D.five hundred of
【答案】A
【详解】
考查数量词。句意:我们图书馆里有几百本书。A. hundreds of 数百;B. hundred of(错误表达);C. five hundreds(错误表达);D. five hundred of+名词“……中的五百 ”;根据句意可知,该句表达有数百本书。故选A项。
4.The new school will be ________ the old one.
A.as big as twice B.twice as big as
C.as bigger as twice D.twice as bigger as
【答案】B
【详解】
考查形容词比较级。句意:这个新学校的占地面积会是原来的两倍大。根据句意,本句应用倍数的表达句式“倍数(once/twice/three times…)+as+形容词或副词的原级+as ...”。故选B。
5.It is reported that the United States uses ___________energy as the whole of Europe.
A.as twice B.twice much
C.twice much as D.twice as much
【答案】D
【详解】
考查倍数表达法。句意:据报道美国使用的能源是整个欧洲的两倍。本题使用的是:“A+倍数 + as + 形容词 + 名词 + as + B”,表示“A的…正好是B的多少倍”。故选B。
点睛:倍数表达要牢记,倍数表达法是高中英语教学的重点,也是历届高考的热点。当我们要表达甲是乙的几倍时,通常用句型来表示: “A+倍数+形容词或副词的比较级+than+B”,表示“A比B大(长、高、宽等)多少倍”。 2.“A+倍数+as+形容词或副词的原级+as+B”,表示“A正好是B的多少倍”。 3. “A+倍数+the size/height/length/width, etc+of+B”,表示“A正好是B的多少倍”。 4. “……times+what+从句”。
