【分析】
本题为根据中文提示填写英语单词的基础题,需结合句子语境、固定句式及词性要求确定单词:1. 提建议的常用疑问句结构对应“将要”的表达;2-5题分别考查核心名词、动词的拼写,需匹配句意和语法规则。
【解析】
1. 表示建议的固定句式“Shall we + 动词原形”,对应中文“将要”的语境,故填Shall;
2. “钱包”的英语名词为wallet,符合“丢了钱包没现金”的句意,故填wallet;
3. “癌”的英语名词为cancer,“cure for cancer”是固定搭配,故填cancer;
4. “现金”的英语不可数名词为cash,some后接原形,故填cash;
5. “通过考试”的固定表达为pass the exam,情态动词can后接动词原形,故填pass。
【答案】
1. Shall 2. wallet 3. cancer 4. cash 5. pass

答案

解析

【分析】
本题为英语单词适当形式填空题,需结合句子的语法结构、语境、时态及代词用法等确定括号内单词的正确形式,具体思路:1. 由many判断需用名词复数;2. 由定冠词the和句意判断需用表示人的名词;3. 由主语人称和语境时态判断动词的第三人称单数形式;4. 由形容词性物主代词their判断需用名词复数;5. 由语境判断需用一般将来时。
【解析】
1. 句意:很多人去音乐会听现场音乐。many修饰可数名词复数,concert的复数形式为concerts,故填concerts。
2. 句意:比赛的获胜者将获得大奖。定冠词the后需接名词,win对应的表示“获胜者”的名词是winner,此处用单数形式,故填winner。
3. 句意:他几乎不练习,所以从来没通过驾照考试。主语he是第三人称单数,结合语境用一般现在时,谓语动词需用第三人称单数形式,pass的三单形式为passes,故填passes。
4. 句意:在拥挤的地方,人们应保管好他们的钱包。their是形容词性物主代词,后接可数名词复数,wallet的复数形式为wallets,故填wallets。
5. 句意:John很友好,我认为他会成为一名好老师。根据语境,此处表达将来的情况,用一般将来时,结构为“will+动词原形”,故填will be。
【答案】
1. concerts 2. winner 3. passes 4. wallets 5. will be
【知识点】

本题为英语基础题型,考查单词适当形式的运用,涉及名词单复数、词性转换、动词时态等核心基础语法,是初中英语常考内容,难度适中,需学生掌握单词的不同形式及语境适配。

三、用more,fewer或less填空
1. She has to eat
less
meat because she wants to be thinner.
2. Be friendly and kind to your friends, or you will have
fewer
friends.
3. Don't worry. We'll give you
more
information.
4. I'm healthier now, because I eat
more
vegetables these days.
5. The cities will be more crowded because there will be
more
people.

答案

1. less 2. fewer 3. more 4. more 5. more

解析

【分析】首先明确more、fewer、less的用法区别:more既可以修饰可数名词复数,也可以修饰不可数名词,意为“更多的”;fewer仅能修饰可数名词复数,意为“更少的”;less仅能修饰不可数名词,意为“更少的”。解题时需先判断每个句子中被修饰的名词是可数还是不可数,再结合句子语境选择合适的词。
【解析】1. 句中meat是不可数名词,结合“想变瘦”的语境,需用表“更少的”且修饰不可数名词的less;2. 句中friends是可数名词复数,结合“对朋友不友好”的语境,需用表“更少的”且修饰可数名词复数的fewer;3. 句中information是不可数名词,结合“别担心,我们会给你”的语境,需用表“更多的”more;4. 句中vegetables是可数名词复数,结合“更健康”的语境,需用表“更多的”more;5. 句中people是可数名词复数(指人,复数形式),结合“城市更拥挤”的语境,需用表“更多的”more。
【答案】1. less 2. fewer 3. more 4. more 5. more
【知识点】形容词比较级(more/fewer/less的用法)、可数名词与不可数名词
【点评】本题是初中英语基础词汇运用题,聚焦易混形容词的用法辨析,要求学生掌握三个词的修饰对象差异,结合语境即可作答,属于基础练习题型。
【难度系数】0.6
四、阅读理解
Would you like to live in a city where buildings turn the lights off for you, and self-driving cars find the nearest parking space themselves? Although it might sound a little far from you, living in a “smart” city like this could happen sooner than you think.
Great changes have taken place in towns that we have lived in for centuries, while completely new cities are being built. One such place is the city of Songdo. Every home there will have a “telepresence” system(远程呈现系统)—allowing users to control the heating and locks, take part in video meetings and receive education, healthcare and government services. Around the city, escalators(自动扶梯) will only move when someone is on them, and offices and schools will all be connected to the system.
The great mind behind Songdo is from the company Cisco. In fact, technology companies around the world such as IBM, Siemens and Microsoft are already in the business.
About 75% of the world’s population will live in cities by 2050, so cities will need to be more modern to deal with the coming problems. “Making cities smarter is one way out, and I think this will in turn make cities greener,” said Dan Hill, the head of a research company.
