[江苏南通2020高一期末]Scientists say they have develped a system that uses machine learning t predict when and where lightning will strike. Researchers reprt the system is able t predict lightning strikes up t 30 minutes befre they happen within a 30-kilmetre radius.
Lightning is a strng burst f electricity in the atmsphere. Since it carries extremely pwerful electric charge，it can be destructive and deadly. Eurpean researchers have estimated that between 6,000 and 24,000 peple are killed by lightning wrldwide each year. Fr this reasn，climate scientists have lng sught t develp methds f predicting lightning.
The system tested in the experiments used a cmbinatin f data frm weather statins and machine learning methds. The researchers develped a predictin mdel that was trained t recgnise weather cnditins that were likely t cause lightning.
The mdel was created with the data cllected ver a 12-year perid frm 12 Swiss weather statins in cities and muntain areas. The data, related t fur main surface cnditins: air pressure, air temperature, relative humidity and wind speed, was placed unique machine learning algrithm(算法), which cmpared it t the recrds f lightning strikes. Researchers say the algrithm was then able t learn the cnditins under which lightning wuld happen.
The researchers tested the system several times. They fund that the system made predictins that prved crrect almst 80 percent f the time.“It can nw be used anywhere,”the Swiss Federal Institute f Technlgy said in a statement.
The researchers plan t keep develping the technlgy in partnership with a Eurpean effrt that aims t create a lightning prtectin prgramme. The effrt is called the Eurpean Laser Lightning Rd prject. Scientists wrking n the prject are experimenting with the laser technlgy that culd smeday cntrl lightning activity, transferring lightning charge frm cluds t the grund. They hpe that such technlgy can ne day be used as prtectin against lightning strikes. Pssible uses culd be at statins, airprts r places where crwds f peple gather.
1. Why was the system develped？
A. T shw the pwer f lightning.
B. T meet kids’ curisity abut lightning.
C. T prtect peple frm lightning.
D. T keep track f deaths caused by lightning strikes.
2. What is special abut the system?
A. It adpted a different machine learning algrithm.
B. It used an effective methd f cllecting data.
C. It was based n a number f samples wrldwide.
D. It required the lw cst f predicting lightning.
3. What will the researchers d next with the laser technlgy?
A. Generate electricity with lightning.
B. Transfer energy frm lightning.
C. Mnitr lightning activity.
D. Prevent the ccurrence f lightning.
4. What can be a suitable title fr the text?
A. A Thery f Emplying Lightning
B. A Mdel f Creating Lightning
C. A System f Cntrlling Lightning
D. A Methd f Frecasting Lightning
答案解析
刷单句填空
1. absence 句意为：由于缺乏明确的目标，我们被困在日常生活中，直到成为生活的奴隶。设空处作介词in的宾语且前有定冠词the限定，应用名词。故填 absence。
2. predictin 句意为：一些人总是把不久后是世界末日的预言当回事。设空处作take的宾语，其前有定冠词the限定，应用名词。故填predictin。
3. n 句意为：到了我们高度重视改善食品安全问题的时候了。place emphasis n意为“重视”，为固定搭配。故填n。
4. in 句意为：微信是一个与他人保持联系以及即时发布位置与动态的不错方式。keep in tuch with为固定搭配，意为“与……保持联系”。

6. buying can’t resist ding sth意为“忍不住做某事”，为固定搭配。故填 buying。
7. advcating 句意为：中国将通过资源保护来保障能源安全，倡导环保的生活方式和消费文化。分析句子结构可知，设空处应用非谓语形式，advcate与主语 China之间是逻辑上的主动关系，故用现在分词作状语。
8. will be imprved 句意为：我们相信环境会在我们减少污染的进步努力下得到改善。设空处作从句的谓语动词，根据句中的further可知，此处指发生在将来的动作，应用一般将来时；imprve与从句主语 the envirnment之间是被动关系，故用被动语态。故填will imprved。
9. will be standing 句意为：从事科学研究的探险家们明天这个时候将站在北极。根据句中的时间状语 this time tmrrw可知，此处指将来某一时刻正在发生的动作，应用将来进行时。故填 will be standing。
10. it make it a rule（t d sth）意为“定下规矩（做某事）”，it是形式宾语，真正的宾语是动词不定式短语。

【语篇导读】本文是一篇说明文，介绍了北欧几个城市正在试行的共享街道，它能够有效地缓解交通堵塞和减少交通事故。
1. faster 根据后面的than可知，此处用形容词比较级，故填 faster。
2. results result是可数名词，前有sme修饰，应用可数名词复数，故填results。
3. is called 句意为：这个系统叫作“共享街道”。call是谓语动词，与主语 The system之间是被动关系，且全文讲的是共享街道当下的状况，时态应为一般现在时，应该用一般现在时的被动语态，故填is called。
4. t g 句意为：虽然大多数人认为这会导致更严重的交通堵塞和交通事故数量的增加，但到目前为止，两者都有大幅度的降低。cause sb/sth t d sth表示“致使某人/某物做某事”，故填t g。
5. there 句意见上一题解析。此处为 there be句型的完成式，表示“已经有”，故填 there。
【易错警示】
There be句型是语法填空中最容易出错的考点。没有提示词时，我们常考虑介词、代词、连词等，而容易忽视特殊句型。语法填空中对There be句型的考查重点在于对句意的理解和句式结构的分析。
6. is 主语是 One reasn，且为一般现在时，故填is。
7. careful 作表语应用形容词，故填 careful。
8. t 句意为：没有了交通规则，人们会放慢速度，更加注意彼此。pay attentin t为固定搭配，意为“注意”，故填t。
9. which 句意为：另一方面，正常的交通系统依赖标志，人们经常注意不到或不遵守（标志），从而导致事故（的发生）。________ peple ften miss r dn’t fllw是非限制性定语从句，修饰先行词 signs，指物，关系词在从句中作宾语，故填 which。
10. freely 修饰动词短语 mve arund应用副词。free作副词意为“免费地；松脱地”；freely作副词意为“自由地；畅通地”。故填 freely。
