Question

15．Most people usually travelled by ship and train which are driven by steam engine．It played an important part in many kinds of vehicles several scores of years ago．Who invented steam engine and what units could be used to measure the power of engine？
The word"horse-power"was first used two hundred years ago．James Watt from a worker's family made the world first widely used steam engine．At first，he couldn't tell people how powerful it was，because there were no units at that time．Watt decided to find out how much work one strong horse could do in one minute．He named that unit one horse-power．In this way he could measure the work of his steam engine．
He discovered that a horse could lift a 3300-pound weight 10 feet into the air in one minute．His engine could lift a 3300-pound weight 100 feet in oe minute．Because his engine did ten times as much work as the horse，Watt called it a ten horse-power engine．

1．The main idea of the passage isB．
A．James Watt invented the steam engine
B．James Watt first used horse-power as a unit of measure
C．how much power does a horse have
D．why Watt's engine is called a ten horse-power engine
2．The story says that Watt made the firstD．
A．engine
B．horse-power engine
C．useful engine
D．widely used steam engine
3．James Watt was born inA．
A．a(chǎn) worker's family       B．a(chǎn) farmer's family
C．a(chǎn) teacher's family       D．a(chǎn) doctor's
4．Watt wanted to find a way toD．
A．measure the work his engine could do
B．tel people how powerful his engine was
C．lift a 3300-pound weight
D．both A and B
5．One horse-power means theA．
A．work a horse could do in a minute
B．weight a horse could do in ten minutes
C．work a horse could do in ten minutes
D．weight of one horse．

Answer 1

分析 本文是一篇人物故事類閱讀．文章主要講述了James Watt發(fā)明第一個(gè)被廣泛使用的蒸汽機(jī)并第一次使用馬力作為計(jì)量單位的故事．

解答 1-5 BDADA
1．B．主旨大意題．縱覽全文并根據(jù)"The word"horse-power"was first used two hundred years ago．James Watt from a worker's family made the world first widely used steam engine．"可知文章主要介紹了James Watt第一次使用馬力作為計(jì)量單位．故選B．
2．D．細(xì)節(jié)理解題．根據(jù)"James Watt from a worker's family made the world first widely used steam engine"可知James Watt做了第一個(gè)被廣泛使用的蒸汽機(jī)．故選D．
3．A．細(xì)節(jié)理解題．根據(jù)"James Watt from a worker's family made the world first widely used steam engine．"可知James Watt出生在一個(gè)工人家庭．故選A．
4．D．細(xì)節(jié)理解題．根據(jù)"he couldn't tell people how powerful it was，because there were no units at that time．Watt decided to find out how much work one strong horse could do in one minute．He named that unit one horse-power．In this way he could measure the work of his steam engine．"可知James Watt想找到一個(gè)方法測量發(fā)動(dòng)機(jī)能做的工作，并告訴人們發(fā)動(dòng)機(jī)有多強(qiáng)大．故選D．
5．A．推理判斷題．根據(jù)"He discovered that a horse could lift a 3300-pound weight 10 feet into the air in one minute．His engine could lift a 3300-pound weight 100 feet in oe minute．Because his engine did ten times as much work as the horse，Watt called it a ten horse-power engine．"可知一馬力相當(dāng)于一分鐘內(nèi)一匹馬所做的工作．故選A．

點(diǎn)評(píng) 本文是一篇人物故事類閱讀．此類題型主要考查學(xué)生的細(xì)節(jié)理解和推理判斷能力．細(xì)節(jié)理解題是針對(duì)文中某個(gè)細(xì)節(jié)、某句話或某部分具體內(nèi)容設(shè)置問題，所以在做細(xì)節(jié)理解題時(shí)要結(jié)合原文和提干有針對(duì)性的找出相關(guān)語句進(jìn)行仔細(xì)分析，再結(jié)合選項(xiàng)選出正確答案．在做推理判斷題時(shí)不要以個(gè)人的主觀想象代替文章的事實(shí)，要聯(lián)系上下文根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．在做主旨大意題時(shí)考生首先要仔細(xì)閱讀短文，完整了解信息，準(zhǔn)確把握作者觀點(diǎn)，確定主旨．
