[集训中明晰考点]
考点1 连接并列成分
1. (2021·新高考Ⅰ卷)Though it is the only unnatural thing on your way up the mountain, still it highlights the whole adventure offers a place where you can sit down to rest your aching legs.
解析:and 空格后的动词offers与前面的动词highlights之间构成并列关系,故填and。
2. (2021·全国甲卷)My bike was old and shaky did the job.
解析:but 根据空处前后的语境可知,“自行车又旧又摇晃”与“能骑”之间是转折关系。故用表示转折的连词but。
3. (2020·浙江1月高考)It's also that they are on average healthier more productive for longer.
解析:and 根据语境可知,healthier和more productive之间构成并列关系,故填and。
4. (2018·全国卷Ⅲ改编)Everyone was silent, waiting to see who would be called upon to read his her paragraph aloud.
解析:or 此处表示“他的或者她的”段落,属于一种选择关系。
考点2 连接并列句式
连词的选择取决于连接的两个分句之间的逻辑关系,并列用and,转折用but,因果用so,for, 选择用either ...or,否定用neither/nor。注意:neither/nor位于句首时要用倒装语序。
1. (2021·浙江1月高考)In a study of 33 years of trends in Body Mass Index (体重指数) across 200 countries, the scientists found that people worldwide are getting heavier that most of the rise is due to gains in BMI in rural areas.
解析:and 分析句子结构可知,此空前后连接两个that引导的宾语从句,且根据语境可知,前后两个从句之间是并列关系,故填并列连词and。
2. (2019·全国卷Ⅱ)I work not because I have to, because I want to.
解析:but 句意:我工作不是因为我不得不工作,而是因为我想工作。not ...but ...为固定结构,表示“不是……而是……”。
3. (2022·肇庆模拟)Yellow represents happiness and joy in some places, in other places it is a symbol of loss.
解析:while 句意:黄色在某些地方代表着幸福和快乐,而在其他地方则代表着损失。分析句子可知,此处连接两个简单句,且表示对比关系,因此使用连词while。
考点3 句型:祈使句+and/or+陈述句
(1)陈述句中的时态原则上用一般将来时;
(2)该句型中and 表示前后句是顺承关系,意思是“那么”;or 表示前后句是转折关系,意为 “否则”。祈使句可以转换为if引导的条件状语从句,这时要去掉连词and/or。
1. (2022·郑州模拟)Compare Wuhu with Shanghai, to be frank, ________ you'll find it's more convenient to live in the former.
解析:and 句意:坦率地讲,把芜湖和上海相比,你就会发现住在前面那座城市中更方便。前后句之间为顺承关系,故填and。
2. (2022·宜春模拟)Don't use your mobile phone while charging, you may be shocked by electricity.
解析:or 句意:不要边充电边使用手机,否则你可能会被电击。根据句意可知,应用or。

while→when
which→them或去掉but
or→and
1.(should) be founded 考查被动语态和虚拟语气。主语a university和动词found之间是被动关系,故用被动语态;suggest表示“建议”时,后接从句,从句用虚拟语气,即谓语动词用“(should+)动词原形”。
2.better 考查副词的比较级。根据语境可知,空处表示“更好地”,故用副词比较级。
3.universities 考查名词复数。university为可数名词,该处表示“其他许多大学”,故用复数形式。
4.donation(s) 考查名词。根据该句中的及物动词raise可知,空处作该及物动词的宾语,故用名词形式。
5.with 考查介词。with表示“具有,带有”。
6.which 考查定语从句。分析该句结构可知,该句为非限制性定语从句,句中his library and half his estate为先行词,故用which引导该定语从句。
7.standing 考查非谓语动词。John Harvard和动词stand之间为逻辑上的主谓关系,故用现在分词作宾语补足语。
8.known 考查形容词。根据空处后的名词“landmark”可知,空处修饰该名词,表示“知名的,著名的”,故用形容词known。
9.a 考查不定冠词。该处泛指“一句格言”,且saying的发音以辅音音素开头,故用不定冠词a。
10.and 考查连词。空前的“Harvard is the crown of American education”和空后的“Harvard Business School is the shining diamond on it”为并列关系,故用连词and。
Ⅳ.短文改错
The first foreign language I never learnt was French, but it didn't go very well. My mother asked our neighbor teach me when I was seven. French wasn't his native languages, but he used to live in France, so he could speak a little. However, I learnt very little until I didn't feel it related to my daily life anyway. When I entered into a senior high school, my attitude to language learning changed. I decided to learn Latin, that I've always been interested in because I want to study law. Learning Latin wasn't a struggle for myself for this reason. Soon I begin to read classics in Latin. Read those books opened a window for me to another world or gave me a new point of view on my own world.
答案:第一句:never→ever
第二句:neighbor后加to
第三句:languages→language
第四句:until→because/since/as
第五句:去掉into
第六句:that→which
第七句:myself→me
第八句:begin→began
第九句:Read→Reading; or→and
