参考答案及试题解析
1.C
【详解】句意:——我完全不知道假期该去哪儿。——为什么不考虑去北京游玩呢?那里有很多名胜古迹。
考查动词辨析。suggest建议;wonder想知道;consider考虑;regard看待。suggest doing sth.意思是建议做某事,但此句是对方给自己提建议,不是我去建议别人,A选项不符合语境;wonder常用表达为“wonder+疑问词+从句”或wonder to do sth.,B选项排除;consider doing sth.表示“考虑做某事”,Why not consider visiting Beijing 意思是“为什么不考虑去北京游玩呢”,符合语境和语法,C选项正确;regard...as...意思是“把……当作……”,D选项不符合。故选C。
2.C
【详解】句意:——电影《流浪地球》给我们讲述了一个人们如何努力拯救地球的故事。——是的。在电影中,人类选择留在地球上,而不是逃离它。
考查介词短语辨析。as for关于,至于;thanks to由于,多亏;instead of代替,而不是;together with和……一起。根据语境可知,此处是在描述电影中人类的选择,即他们选择留在地球上,而不是逃离。所以应该用instead of来表示“而不是”的意思。故选C。
3.B
【详解】句意:对许多外国人来说,上海已经成为他们的第二故乡。
考查数词。two二;second第二;the second第二。这里是说把上海当做第二故乡,表示第几用序数词,序数词前有形容词性物主代词时不用定冠词the。故选B。
4.D
【详解】句意:这是我第一次来这里,希望有人能多多帮助我。
考查序数词。first是序数词,前面一般加the,但是当序数词前有形容词性物主代词时,不用the。故选D。
5.B
【详解】句意:一个8岁的男孩帮我找到我的车钥匙。
考查年龄表达法。根据句子结构可知,空格处是定语,修饰名词boy。8-year-old是复合形容词,year后不能加s;8 years old是名词短语,year后必须加s,由数词及名词构成的复合形容词,各词之间应加连字符,且中间的名词用单数形式。故选B。
6.A
【详解】句意:托尼的母亲看起来很年轻漂亮。很难想象她已经五十多岁了。
考查年龄表达。在某人几十岁:in one’s +整十的复数,故选A。
7.B
【详解】句意:——这个游泳池有多长?——它50米长 。
考查长度表达方式。50-metre long表达错误;50 metres long50米长;50 metres’ long表述错误;50-metre-long50米长的。根据题干可知,问句询问物体的长度,答句需回答具体的长度,表达方式为“数词-单位-形容词”,metre意思是“米”,为可数名词,在本题中需用复数形式,故选B。
8.D
【详解】句意:今年7月1日是中国共产党95岁生日。
考查数词的用法。根据“July 1st of this year is the…birthday of the CPC”可知,此处说的是第95个生日,应该用序数词ninety-fifth。故选D。

考查数词。hundred百,基数词;hundreds数百,表示泛指;hundredth第一百,序数词;hundreds of数百的,表示泛指。根据“birthday”可知,此处表示“第一百个生日”,要用序数词表示顺序,故选C。
10.A
【详解】句意:2025年有365天。
考查基数词和序数词的用法。three hundred and sixty-five 三百六十五;three hundred and sixty-six 三百六十六;three hundred sixty-fifth 第三百六十五(序数词);three hundred and sixty-sixth 第三百六十六(序数词)。根据常识,平年有365天,闰年有366天。2025年不是闰年,因此有365天。故选A。
11.D
【详解】句意:这是一条200米长的河流,且那条河流长300米。
考查长度的表达。在英语中,当表示长度、宽度、高度等作定语时,通常使用“基数词+连字符+单位+连字符+形容词”的形式,且单位不加复数形式。第一个空位于名词river前,作定语,用200-meter-long;而在用作表语时,通常用“基数词+单位+形容词”结构。第二个空位于is后,作表语,基数词为300,meter用复数的meters,第三个空填300 meters long。故选D。
12.A
【详解】句意:Jerry是一个8岁的男孩,但他能照顾好自己。
考查复合形容词。空处位于名词boy前,填形容词作定语,用8-year-old,表示“八岁的”;8 years old在句中作表语,可排除。故选A。
13.C
【详解】句意:我是家里的第二个孩子。我有一个哥哥和一个妹妹。
考查序数词。only one只有一个;the first第一;the second第二;the third第三。根据“I have an elder brother and a younger sister.”可知,我有一个哥哥和一个妹妹,因此我是家里的第二个孩子,所以此处应用the second,表示“第二”。故选C。
14.B
【详解】句意:John在他三十多岁的时候开始自力更生。
考查年龄表达法。in his thirty错误表达;in his thirties在他三十多岁时;in the thirty错误表达;in the thirties在三十年代。根据“John began to make a living by himself”可知,此处用in his thirties,表示“在他三十多岁时”。故选B。
15.B

考查数词。forty40;forty-five45;fifty50;fifty-five55。根据“twenty girls and twenty-five boys”可知,一共45个学生,故选B。

17.A
【详解】句意:——珍妮为什么这么开心?——因为今天是她的第五个结婚周年纪念日。
考查序数词的用法。fifth第五;the fifth第五;five五;the five五。“anniversary”是单数,此处指第五个结婚纪念日,应用序数词。因空前有代词“her”修饰,序数词前不加定冠词the。故选A。
18.C
【详解】句意:这是我的朋友。他是一个14岁的男孩。
考查基数词。14-years-old,错误形式;14 years old,14岁,作表语;14-year-old,14岁的,作定语。此处在boy前作定语,用14-year-old。故选C。
19.B
【详解】句意:——Sue,你的爷爷多大年纪了?——79岁。
考查数词的正确表达。根据英语数词的书写规则,79应写作 “seventy-nine”,中间需用连字符连接。故选B。
20.A
【详解】句意:这条河很长,大约有20米宽。
考查长度的表达。20 meters wide20米宽;15 meters long15米长;30 meters high30米高。根据题干中“long”这个解题关键,说明河流很长,因此需要选描述宽度的选项来补全句意,A选项是“20 meters wide”。故选A。
21.B
【详解】句意:我的生日在7月21日。
考查序数词的表达。根据句意,结合选项可知,此处指7月21日,21 的序数词是 21st。故选B。
22.D

考查日期的表达。3月三号可表示为:March the third或the third of March,故选D。
24.C

考查日期的表达。the February 25错误表达;the February 21st 错误表达,月份前不加the;February 12th二月十二号;February the 12nd错误表达,序数词“第十二12nd”简写错误。英语中日期的表达可以是“月份加序数词简写”。故选C。
25.A
【详解】句意:——这是我的第三个篮球。 ——哇,我觉得你很喜欢打篮球。
考查数词用法。third第三;three基数词,三。根据“This is my … basketball”可知,此处指的是“第三个”,应用序数词,序数词前已有形容词性物主代词修饰,就不用需要再用the修饰,故选A。
26.C
【详解】句意:——你妈妈的生日是什么时候?——她的生日是2月12日。
考查日期的表达。英语中日期的表达可以是“月份加序数词”简写,月份名词前不能加定冠词,故排除ABD。故选C。
27.A
【详解】句意:——今天几号?——今天是三月八日。
考查日期表达。March the eighth三月八日;March eight形式错误;eight March形式错误;eighth March形式错误。根据“What’s the date today ”可知,此处应回答日期,表示日期应用序数词,三月八日用March the eighth或者March 8th表示。故选A。
28.A
【详解】句意:据说湖里的大鱼大约有四米长。
考查长度的表达。英语中,表示长、宽、高、面积等时,用“基数词+单位词 (meter, foot, inch, kilogram等)+形容词 (long, wide, high, tall等)”表示;此处应用“four meters long”表示“四米长”,在句中作表语;前有基数词“four”,所以名词meter应用其复数形式meters。故选A。
29.A
【详解】句意:——你妹妹多大了?——她八岁了。
考查年龄的表达。表示某人几岁的确切年龄,用“基数词+years old”,所以八岁应是“8 years old”。故选A。
30.B
【详解】句意:她的父亲身高1.78米。
考查身高的表达。当meter“米”前面的数字大于1时,meter需要用复数形式meters,且表示“(身)高”的tall要放在meters后面。故选B。
31.A
【详解】句意:——你多大了?——我五岁了。
考查数词。five五;fifth第五;fiveth错误表达;fiveteen错误表达。根据空后的“years”为名词复数及语境可知,此处指五岁,表示数量,用基数词five。故选A。
32.B
【详解】句意:我们学校的教学楼大约15米高。
考查表示高度的表达。“数词+单位名词+形容词”形式用于表达高度。15-metre-high形式通常作定语。故选B。
33.C
【详解】句意:今天是托尼的生日。今天是他十一岁生日。
考查序数词的用法。根据“birthday”可知其前应用序数词表示顺序,即“第十一个生日”,应用序数词eleventh,或11th,前面有物主代词修饰,应省略定冠词。故选C。
34.B
【详解】句意:我姑姑在我十岁生日时送给我一辆自行车作为礼物。
考查序数词。根据语境和选项可知,此处是表达“第十个生日”,应用序数词tenth,且空前有形容词性物主代词my,序数词前不加the。故选B。
35.B
【详解】句意:——那个女孩多大了?——她13岁。
考查年龄的表达。13-years-old 13岁的,作定语;13 years old 13岁,作表语;A、C两项表述错误。空处在句中作表语,所以用13 years old。故选B。
36.D
【详解】句意:十年前人们在这里种了一棵树,现在这棵树有3米高。
考查数词用法。three-meter-tall三米高,只能做定语,位于名词前;three-meters-tall表达错误;three meter tall表达错误;three meters tall三米高。根据“And now the tree is”可知,作表语时数词后跟名词复数形式,不用连字符。选D。
37.C
【详解】句意:这个男孩1岁。
考查年龄的表达。表达年龄应用“基数词+year(s)+old”,此处由于基数词为1,故year应用原形,“1岁”1 year old。故选C。
38.C
【详解】句意:安德鲁是一个18岁的男孩。他来自于美国西部。
考查基数词年龄段表达法辨析。an 18-year-old一个十八岁的。根据“boy”可知,前面应用形容词修饰,18岁的应表达为18-year-old,且首字母发音为元音音素,故用an。故选C。
39.A
【详解】句意:她今年12岁。
考查年龄的表达。“12岁”可以直接说12或12 years old。故选A。

42.B
【详解】句意:这个洞有两米深。小心不要掉进去。
考查深度、高度等表达。根据“Be careful not to fall into it.”可知,此处表示深度用deep,排除A和C选项;英语中长度宽度等的表示方法为“基数词+单位词+形容词”,基数词超过1的,后单位词需要用复数形式,所以B选项正确;D选项三个单词之前都需要连字符,且只能放在名词前作定语。故选B。
43.D
【详解】句意:爱丽丝11岁了,她有一个8岁的妹妹。
考查年龄表达。表示“……岁”时,用“数字+years old”;表示“……岁的”时,用“数字-year-old”,并且“8-year-old”这样的表达是形容词性的,后面可以接名词sister。故选D。
44.B

考查年龄的表达。thirteen years old表示 “13岁”,选项A、C、D写法错误。故选B。
45.C
【详解】句意;他在二十多岁时离开家去不同的城市工作。
考查介词与时间段搭配。在英语中表示年龄时,如果是整体年龄段,需要使用复数形式并搭配介词“in”,一般用“in one’s+几十的复数形式”来表示不确切的岁数。“in his twenties”是指一个人年纪在20到29岁之间,用于表示一个人在二十多岁时的范围。根据句意,此处是“在他二十多岁的时候”英文表示为“in his twenties”符合。故选C。
46.C
【详解】句意:——你的英语书有多长?——它有近30厘米长。
考查基数词中长度的表达。根据“How long is your English book ”可知,此处表达长度,其结构为:基数词+单位词(复数)+形容词,因此符合题意的只有选项C。故选C。

考查年龄表达。three years old三岁;three-years-old错误表达;three year old错误表达;three-year-old三岁的。此处修饰名词girl,用复合形容词用“数词-名词单数-形容词”表示,three-year-old符合。故选D。
53.B
【详解】句意:——金茂大厦有多高?——大约420米高。
考查数词。分析句子,设空处指的有多高,420 metres high“420米高”符合题意。故选B。
54.D
【详解】句意:陈先生1980年搬到北京,但他在50岁时买了第一套房子。
考查数词用法。根据“but he bought his first house”可知,本句是一般过去时,可排除C选项;in one’s+整十基数词的复数形式,表示“在某人几十多岁的时候”,可排除AB选项。at the age of fifty表示“五十岁的时候”,用于一般过去时。故选D。
55.C
【详解】句意:我爷爷九十多岁了,但幸运的是他还能照顾自己。
考查基数词。on his ninetieth在他90岁时;on his nineties表达错误;in his nineties九十多岁时;in his ninetieth表达错误。结合“but luckily he can still take care of himself.”可知,这里是指爷爷90多岁了。故选C。
56.B
【详解】句意:第三十一届大运会在成都举行。
考查数词。thirty-one三十一,基数词;thirty-first第三十一,序数词;thirty and one错误形式。此处表示第三十一届,要用序数词表顺序。故选B。
57.C
【详解】句意:李文是一个普通的15岁农村男孩。他学习努力,在学校表现很好。
考查年龄表达。 根据“a normal … boy”可知,此处应用a 15-year-old boy,意为“一个15岁的男孩”,15-year-old作前置定语,应用连词符号连接,中间的名词year不能用复数。故选C。
58.B
【详解】句意:这次歌唱比赛的获胜者是一个来自中国名叫张梅的19岁女孩。
考查年龄表达。19-years-old错误;19-year-old十九岁的;19 year old错误;19 years old十九岁。通常在句中作表语。“十九岁的”要用19-year-old,year不能用复数,且要用连字符连接,此处作定语修饰girl要用复合形容词19-year-old。故选B。
59.B
【详解】句意:我们的党是1921年成立的。我们将在今年7月1日庆祝她的100岁生日。
考查序数词。one hundred一百,为基数词;one hundredth第一百,为序数词。根据“her ... birthday”可知,此处表示第一百个生日,要用序数词,第一百one hundredth,序数词前面有物主代词时,省略冠词。故选B。
60.B
【详解】句意:我们确信他能表现得更好,但他在比赛中只获得了第五名。
考查序数词。根据“but he only finished...in the competition”可知,此处表示的是在比赛中的排名,可用“finish+序数词”,表示“排名第几”,因此空处应是fifth。故选B。
