一、选择题1．--How does Jerry go to Shanghai? -- train.A．On B．In C．By D．To C解析：C【解析】句意：——杰瑞怎样去上海？——乘火车。
考查介词辨析题。
on用于交通工具有短语“on foot步行”，in和to都不用于表示交通工具，可排除ABD；“by+交通工具”表示交通方式，固定用法；by train坐火车；根据句意语境，可知选C。
2．John is only a ________ boy, but he can do lots of housework.A．ten--years--old B．ten--year--oldC．ten years old D．ten year old B解析：B【详解】句意：John只是一个十岁的男孩，但是他会做很多家务。
ten-years-old形式错误，years应变为单数；ten-year-old十岁的，是复合形容词，作定语，修饰名词；ten years old十岁，后不能跟名词；D选项中year应变为复数。
空后boy是名词，因此这里应表示“十岁的”，故选B。
3．How far is ________ from your home ________ the library?A．it; to B．this; toC．that; in D．it; in A解析：A【解析】【详解】句意：从你的家到图书馆有多远？it非人称代词，指距离；this这个；that那个；to到…；in在…里面。
根据句中的How far可知，这里询问的是距离，应用it，先排除B和C；from…to…从…到…是固定搭配，故应选A。
4．—I often have hamburgers for lunch.—You'd better not.It's a bad habit ________ too much junk food(垃圾食品)．A．eat B．to eatC．eating D．to eating B解析：B【解析】【详解】句意：--我经常午饭吃汉堡。
--你最好不要这样。
吃太多垃圾食品是一个不好的习惯。
根据句意可知这里“吃太多垃圾食品” 作句子的主语，句首it是形式主语，故后面要用to do 不定式作真正的主语，故选B。
5．My brother has a healthy living habit. He stays up late, and he is an early bird.A．usually B．hardly C．often D．always B解析：B【详解】句意：我哥哥有一个健康的生活习惯。
他几乎不熬夜，而且是早起的人。
A. usually通常；B. hardly几乎不；C. often经常；D. always总是。
健康的生活习惯应该是不熬夜，故答案为B。
6．The engineer（工程师） early every morning to catch the first bus.A．gets up B．stands up C．looks up D．gives up A解析：A【解析】【详解】句意：这位工程师每天早上很早起床去赶早班公共汽车。
stand up站起来；look up查阅；give up放弃。
根据句中early、morning和catch the first bus可知此处应用动词短语get up，意为“起床”，故选A。
7．—How far is the small town from London?—It's about ______ kilometers.A．two hundred and thirty five B．two hundreds and thirty fiveC．two hundreds and thirty-five D．two hundred and thirty-five D解析：D【详解】句意：——这个小镇离伦敦有？——大约235公里。
考查数字的表达。
表示英语数字235时，百位数用“two hundred”表示，hundred无词形变化；35用thirty-five表示，与百位数之间用and连接，因此应用two hundred and thirty-five 表达。
故选D。
8．My Chinese teacher is like a father ______ me.A．for B．to C．at D．on B解析：B【详解】句意：我的语文老师对我像父亲一样。
考查介词辨析。
for为了；to对于；at在；on在……之上。
根据题意“我的语文老师像一个父亲____我”可知此处用to符合题意。
故选B。
9．It takes about 15 minutes ______ there.A．walk B．to walk C．walk to D．walking B解析：B【详解】句意：走路去那里花费大约15分钟。
考查it作形式主语。
walk走路。
根据题干可知此处用“It takes sb. some time to do sth.”句式，意为“做某事花费某人多长时间”，“It”在句中是形式主语，真正的主语是动词不定式短语to walk there。
故选B。
10．We need an hour ______ home.A．get to B．to get to C．get D．to get D解析：D【详解】句意：我们需要一个小时能到家。
考查不定式作目的状语及副词的用法。
get to到达。
根据题干可知此处要用不定式在句中表目的；home是地点副词，其前不用介词to，get home意为“到家”。
故选D。
11．— look at the girl in the square!— Oh. I'm surprised that a ________ girl can dance so well!A．three-years-old B．three-year-old C．three years B解析：B【详解】句意：——看广场上的女孩。
——噢，我很惊讶一个三岁的女孩能跳舞跳得这么好。
考查复合形容词。
three-years-old表达错误，因为复合形容词中的名词用单数；three-year-old三岁的，复合形容词；three years三年，名词短语。
空后girl是名词，应用形容词修饰。
故选B。
12．— ________ have you been here?— I have been here for five years.A．How soon B．How much C．How long D．How far C解析：C【详解】句意：——你在这里多长时间了？——我在这里已经五年了。
考查疑问词短语辨析。
How soon多久，对表将来的时间“in+时间段”提问；How much多少，对不可数名词或价格提问；How long多长，询问时间或物体的长度；How far多远，询问距离。
答语中for five years表示一段时间，应用How long提问。
故选C。
13．I usually go home ________ bike but today I ________ a bus.A．by; take B．take; by C．take; take D．by; by A解析：A【详解】句意：我通常骑自行车回家，但今天我坐公共汽车。
考查词汇辨析。
by表示乘坐，是介词，结构为“by+交通工具”；take表示乘坐，是动词，结构为“take +a/an/the +交通工具”。
第1空后bike是交通工具，应用介词by；后分句缺少谓语，应用动词take。
故选A。
14．It's difficult _______ her _______ to school because she lives far from the school. A．to；to get B．to；get C．for；to get D．for；get C解析：C【解析】【详解】句意：她上学很困难，因为她住在离学校很远的地方。
本题考查固定句型：It is+形容词+for sb. to do sth. 做某事对某人来说是⋅⋅⋅⋅⋅⋅样的。
故选C。
15．—How long does it take you?—The ________ takes me half an hour.A．ride bus B．bus ride C．rides bus D．buses' ride B解析：B【详解】句意：——你要花多长时间?——坐公共汽车要花我半个小时。
考查名词，根据提问“How long”可知是对时间的提问，回答应该是时间。
观察句子，这里缺少主语，名词bus作定语修饰ride“旅行，行程”，表示“乘坐公共汽车的路程”，符合语境，故选B。
16．—How amazing this robot is!—Wow, it has video cameras in its eyes, so it “see” and interact with people.A．may B．can C．must B解析：B【解析】【详解】句意——多么神奇的机器人！——哇，它的眼睛里有摄像机在，所以它可以“看到”并能与人交流。
考查情态动词。
A. may可能 B. can表能力 C. must必须。
