A．five hundreds B．hundred of C．five hundreds of D．five hundred 【答案】D 【解析】考查数词。句意：在我们学校有五百名学生。hundred：百，是基数词，基数词+hundred：几百；“five hundred”表示“五百”。故选D。 【考点二：考查序数词用法】 7．I am _______ child in my family.

A．two third B．two thirds C．second third D．second thirds 【答案】B 【解析】 考查分数的表达。句意：在我们学校大约三分之二的学生是女孩子。根据“About...of the students”可知，此处指大约三分之二的学生。分数的表达法：分子用基数词，分母用序数词，当分子超过一，分母用复数，two thirds表示“三分之二”。故选B。 23．________ of the money ________ used out. We have to cut down daily use. A．Three fifth; has B．Three fifth; have been C．Three fifths; has been D．Three fifths; have 【答案】C 【解析】考查数词和主谓一致。句意：五分之三的钱已经用完了。我们必须减少日常使用。第一空处，英语中，表示分数时， 分子用基数词分母用序数词，分子大于1时分母变复数，“五分之三”应表达为“Three fifths”。第二空处，分数后接名词或代词作主语时，谓语动词的单复数取决于名词或代词的单复数，本题中 money 是不可数名词，故谓语动词用单数，“money”是被使用的，需用被动语态；再根据“We have to cut down daily use.”可知，此处强调“钱已经被用完”，应用完成时的被动语态（have/has been + 动词过去分词）。故选C。 24．________ of the students in our class are girls. A．Three fourth B．Threes fourth C．Three fourths D．Third fourths 【答案】C 【解析】考查分数表示法。句意：我们班四分之三的学生是女生。英语中分数的表示法，分子用基数词，分母用序数词，当分子大于1时，分母用复数，“四分之三”的正确表达是“Three fourths”。故选C。 25．—You’ve eaten too little. ________ of the milk ________ still left in the bottle. —I’m full now.

A．third fifths; is B．third fifth; are C．three fifth; is D．three fifths; are 【答案】D 【解析】考查分数表达及主谓一致。句意：在我们班，五分之三的学生是女生。对于分数的表达，分子用基数词，分母用序数词。当分子大于1时，分母要用复数形式。“五分之三”的正确表达是“three fifths”；当分数作主语时，谓语动词的单复数取决于分数所修饰的名词，“students”是复数名词，所以谓语动词要用复数形式“are”。故选D。 27．________ of the teachers in our school are from the south. A．Two sixths B．Two sixth C．Sixthes two D．Sixths two 【答案】A 【解析】考查分数表达法。句意：我们学校六分之二的老师来自南方。分数的基本结构为：分子用基数词，分母用序数词。当分子大于一时，分母需用复数形式，因此A项符合题意。故选A。 28．The number of the fans going to this concert is about three ________.

A．thousand; two third B．thousands; two third C．thousand; two thirds D．thousands; two thirds 【答案】C 【解析】考查数词。句意：去这场音乐会的粉丝人数约为三千人，其中三分之二是女孩。thousand被具体的基数词修饰时，thousand用单数形式，且不与of连用，表示具体的数量。根据“three”可知，第一个空应用thousand；英语中，表示分数时，分子用基数词，分母用序数词，当分子大于1时，分母中的序数词要变为复数，故“三分之二”的正确表达是two thirds。故选C。 29．________ of the surface of the earth is covered by water. A．Two third B．One thirds C．One half D．Two thirds 【答案】D 【解析】考查分数表达法。句意：地球表面的三分之二被水覆盖。分数词由基数词和序数词构成；分子用基数词，分母用序数词，分子超过1时，分母用复数。根据“of the surface of the earth is covered by water.”可知，地球上的水覆盖了三分之二以上的地表，“Two thirds”表示“三分之二”。故选D。 【考点四：考查时间表达法】 30．My grandfather retired ________.

A．twenty-five past five B．twenty-five to six C．twenty-five to five D．thirty-five to six 【答案】B 【解析】考查时间表示法。句意：—现在几点了？—现在是五点三十五分。在英语中，当分钟数小于等于30分钟时，常用“分钟数+ past +整点”的结构来表达时间，意为“几点几分”；当分钟数大于30分钟时，常用“（60－分钟数）+ to +（下一个整点）”的结构来表达时间，意为“距几点还差几分”；因此，“5:35”应用“twenty-five to six”来表示。故选B。 34．________, great changes took place in China.

A．The number of; four-fifths B．A number of; four-fifth C．A number of; four-fifths D．The number of; four-five 【答案】C 【解析】考查固定搭配及分数表达。句意：许多人更喜欢华为手机，其中约五分之四是成年人。The number of表示“……的数量”，谓语动词使用单数；A number of表示“许多，大量”，谓语动词使用复数。分数表达中，分子使用基数词，分母使用序数词，当分子大于1时，分母的序数词用复数。第一空，谓语动词“prefer”是动词原形，由此可知，此处表示许多人，应使用A number of；第二空，五分之四的分子大于1，因此应使用four-fifths。故选C。 38．My grandfather still plays tennis _______ A．in his seventy B．in his seventies C．at his seventy D．at his seventies 【答案】B 【解析】考查年龄的特定表达法。句意：我爷爷七十多岁了还在打网球。“in one’s + 整十复数”表示“在某人几十多岁的时候”，“在某人七十多岁时”表达为“in his seventies”。故选B。 39．In ________ year, students in the vocational school begin to get hands-on experience by doing internship.
