1、阅读微技能训练4细节理解题(1)I. Reading comprehensionCHELYABINSK, Russia - A meteorite(piece of rock or metal that has reached the earths surface from out space) streaked across the sky and exploded over central Russia on Friday, raining fireballs over a vast area and causing a shock wave that smashed windows, d
2、amaged buildings and injured 1,200 people.People heading to work in Chelyabinsk heard what sounded like an explosion, saw a bright light and then felt the shock wave, according to a Reuters correspondent in the industrial city 1,500 km (950 miles) east of Moscow. The fireball, travelling at a speed
3、of 30 km (19 miles) per second according to Russian space agency Roscosmos, had blazed across the horizon, leaving a long white trail that could be seen as far as 200 km (125 miles) away.Car alarms went off, thousands of windows shattered and mobile phone networks were disrupted (扰乱). The Interior M
4、inistry said the meteorite explosion, a very rare spectacle, also unleashed a sonic boom (音爆).I was driving to work, it was quite dark, but it suddenly became as bright as if it were day, said Viktor Prokofiev, 36, a resident of Yekaterinburg in the Urals Mountains. I felt like I was blinded by head
5、lights.The meteorite, which weighed about 10 tonnes and may have been made of iron, entered Earths atmosphere and broke apart 30-50 km (19-31 miles) above ground, according to Russias Academy of Sciences. The energy released when it entered the Earths atmosphere was equal to a few kilotonnes, the ac
6、ademy said, the power of a small atomic weapon exploding.The Emergencies Ministry said 20,000 rescue and clean-up workers were sent to the region after President Vladimir Putin told Emergencies Minister Vladimir Puchkov to ease the disruption and help the victims. The Interior Ministry said about 1,
7、200 people had been injured, at least 200 of them children, and most from shards (碎片) of glass.Experts drew comparisons with an incident in 1908, when a meteorite is thought to have devastated an area of more than 2,000 sq km (1,250 miles) in Siberia, breaking windows as far as 200 km (125 miles) fr
8、om the point of impact.Simon Goodwin, an expert from Britains University of Sheffield, said that roughly 1,000 to 10,000 tonnes of material rained down from space towards the earth every day, but most burned up in the atmosphere. While events this big are rare, an impact that could cause damage and

Forget about placing an order, paying the bill online and waiting for days for it to be delivered to you. In the near future, youll be
14、able to get it in minutes just by hitting “print on your computer.You might find it hard to believe that you could actually “print an object like you would a picture. But it is not that hard to understand how it would work. Just as a traditional printer sprays ink onto paper line by line, modern 3-D
15、 printers spread material onto a surface layer by layer, from the bottom to the top, gradually building up a shape.Instead of ink, the materials the 3-D printer uses are mainly plastic, resin and certain metals. The thinner each layer is from a millimeter to less than the width of a hair the smoothe
16、r and finer the object will be.This may sound like a completely new technology, but the truth is that 3-D printing has been around since the late 1980s. Back then, it was barely affordable for most people, so few knew about it.Last year, though, saw a big change in the 3-D printing industry printers
17、 became much cheaper. For example, 10 years ago a desktop 3-D printer might have cost 20,000 (200,000 yuan), while now they cost only about 1,000, according to the BBC.Taken out of the factory and introduced to more diverse and common uses, 3-D printing can create just about anything you can think o
18、f flutes, bikinis, jewelry, aircraft parts and even human organs. In fact, scientists from Cornell University in New York have just made an artificial ear using a 3-D printer, according to Science Daily. The fake ear looks and acts exactly like a natural one.However, as 3-D printing becomes more com
19、monplace, it may trigger certain problems such as piracy. “Once you can download a coffee maker, or print out a new set of kitchen utensils on your personal 3-D printer, who will visit a retail store again? an expert in 3-D printing told Forbes News. Even more frightening, what if anyone in the worl
20、d could use a 3-D printer to print out a fully functioning gun?1. According to the article, in the future, the 3-D printing technology will _.A. enable people to make better purchases onlineB. be applied as widely in our daily lives as computersC. revolutionize the way we make many productsD. shorte

The 3-D printer became more affordable for consumers.C. The 3-D printer was used for medical treatment f
22、or the first time.D. 3-D printing technology began to be used in various fields.3. How is the last paragraph developed?A. By analyzing a cause and an effect.B. By making comparisons.C. By giving examples.D. By presenting research findings.(B)LAST year, more than a quarter million people worldwide di
23、ed from pancreatic (胰腺的) cancer. After losing a close family friend to the disease, Jack Andraka, 16, learned firsthand just how deadly it can be.That prompted the American teenager to create a simple and inexpensive test to detect pancreatic cancer at its earliest stage of development. Typically, t
24、he cancer is not discovered until it has reached later stages. So, Andrakas invention is a breakthrough that could save many lives.How does a teenager create a test that scientists have been trying to figure out for years?“I got all of my information from the Internet, Andraka said.Andraka said the
25、whole project started when a family friend died from pancreatic cancer.This made him take a sharp turn from his interest at the time: studying the impact that nano-particles tiny particles found in consumer products like makeup and sunscreen have on the environment.From the Internet, Andraka learned
26、 that people with pancreatic cancer have elevated (提升) levels of a protein called mesothelin in their blood, and that early detection is key to increasing the chances of survival.He was so absorbed in his work that he snuck it into his biology class to read on his lap under his desk. His teacher cau
27、ght him and took the papers away, Andraka said.Realizing he needed a place to work, he sent 200 letters to researchers around the country asking for permission to use their laboratories. He received 199 rejections and one “maybe from a professor at Johns Hopkins University. There, he was interviewed
28、 at the lab and finally earned an “OK for his project.Starting from a $1,500 (around 9,370 yuan) budget, he began growing cells and other materials once again, he got these from the Internet using the equipment in the lab. For six months, he worked on a solution until he had enough proof that it wor

What inspired Andraka to work on pancreatic cancer?A. His teachers encouragement
30、. B. The death of one of his family friends.C. His parents suffering from the disease.D. His strong interest in medical research.5. In what way is Andrakas invention revolutionary?A. He proved that nano-particles could be used to detect pancreatic cancer at an early stage.B. He discovered a solution
31、 which can make patients with pancreatic cancer fully recover.C. He invented an effective way to help patients to lower levels of mesothelin in their blood.D. His method for detecting pancreatic cancer is simpler, cheaper and faster than current methods.6. How did Andraka collect most of the informa
32、tion he needed for his research?A. By surfing the Web.B. By looking things up in libraries.C. With the help of a professor at Johns Hopkins University.D. By interviewing researchers around the country.7. Which of the following can best describe Andraka?A. Hes good at persuading people.B. He is addic
33、ted to advanced technologies.C. Once he sets a goal, he is determined to achieve it.D. In his teachers eyes, he is imaginative and attentive.(C)IT was just after sunrise on Feb 15. Anna Kolesnikova, 31, was getting ready for work when she looked out her window and saw a big burst of light in the sky
34、. Suddenly she heard a loud explosion and the door to her balcony flew open. All of the car alarms on the street were going off. Kolesnikova crouched down in fear, bewildered as to what was going on.Just like Kolesnikova, residents of Chelyabinsk, the Russian city 1,500 kilometers east of Moscow, we
35、re all thrown into a panic. “My first thought was that it was a plane crash, a resident told The (London) Guardian. But what had actually happened was beyond their wildest guesses it was a meteor (陨石) falling to Earth. The meteor entered the atmosphere at a speed of 52,000 kilometers per hour, about
36、 15 times the speed of a bullet, according to Xinhua News Agency. It then exploded into tiny pieces before reaching the ground. The force from the explosion was so strong that it blew out windows and damaged buildings. Nearly 1,200 people were injured by flying glass, but fortunately no one was stru
37、ck directly by a falling piece of meteor.Scientists from Russias Academy of Sciences said that the meteor weighed about 10 tons and was probably made of iron. One of the meteor pieces was found to have crashed into a frozen lake, leaving a 6-meter-wide hole in the ice, The Guardian reported.However,
38、 this meteor is not the only alien object that has put Earth in danger. Less than a day after the meteor hit, an asteroid (小行星), known as DA14, passed by the Earth at a proximity of 27,520 kilometers, even closer than some television and weather satellites.These two incidents aroused concerns about
39、objects falling from space. Dmitry Rogozin, Russias deputy prime minister, called for an international push to create a warning system, because for now, “neither the US nor Russia has the capability to bring down such objects.But Simon Goodwin, an astrophysics expert from Britains University of Shef
40、field, said that there is no need to worry since such incidents are so rare. About 1,000 to 10,000 tons of meteors fall toward Earth every day, but most burn up in the atmosphere.8. The underlined word “bewildered in the first paragraph probably means _.A. annoyed B. confused C. disappointed D. curi
41、ous9. When the meteor fell to Earth in Russia, _.A. most of it was forced to land in remote areas to reduce destructionB. it caused explosions and resulted in great loss of life and destruction of buildingsC. the shockwave from its explosion caused most of the damage and injuriesD. it remained in on
42、e piece and traveled much faster than a bullet10. By mentioning DA14 in Paragraph 5, the author intends to _.A. show that objects fall from space frequentlyB. show that there are concerns about objects falling from spaceC. inform readers about constant threats to EarthD. compare the asteroid and the
43、 meteor that hit Russia11. What can we infer from the text?A. The number of meteors falling toward Earth may be on the rise in the future.B. Most of the meteors falling toward Earth are destructive and uncontrollable.C. There are warning systems for objects falling from space in certain countries.D. There are no existing technologies that can bring down meteors falling toward Earth.
