科普知识类
阅读下列四篇短文，从每小题后所给的A,B,C或D四个选项中，选出最佳选项。
FILTON, just outside Bristol, is where Britain’s fleet of Concorde supersonic（超音速的）airliners was built. There, something remarkable is being created. Little by little a machine is “printing” a complex titanium bracket (钛合金支架), about the size of a shoe, which normally would have to be cut from a solid block of metal. Brackets are only the beginning. The researchers at Filton have a much bigger ambition: to print the entire wing of an airliner.
Unrealistic as this may seem, many other people are using 3D printing technology to create similarly remarkable things. These include medical implants, jewellery, football boots designed for individual feet, lampshades, racing-car parts, solid-state batteries and customized mobile phones. Some are even making mechanical devices (仪器). At the Massachusetts Institute of Technology (MIT), Peter Schmitt, a PhD student, has been printing something that is like the workings of a grandfather clock. It took him a few attempts to get right, but eventually he removed the plastic clock from a 3D printer, hung it on the wall and pulled down the counterweight. It started ticking.
Engineers and designers have been using 3D printers for more than a decade, but mostly to make original types quickly and cheaply before they embark on the expensive business of tooling up a factory to produce the real thing. As 3D printers have become more able to work with a broader range of materials, including production-grade plastics and metals, the machines are increasingly being used to make final products too. More than 20% of the output of 3D printers is now final products rather than original types, according to Terry Wohlers, who runs a research firm specializing in the field. He predicts that this will rise to 50% by 2020.
1. Which of the following is true according to the passage?
A. Filton is in the centre of Bristol.
B. Peter tried to print a clock, but in vain.
C. a remarkable metal bracket is being created.
D. 3D printing technology is available to all of us.
2. The underlined word “embark” probably means “_________”.
A. workB. landC. dependD. fix
3. We can conclude from the last paragraph that __________.
A. Terry Wohlers’ s firm will make great profits
B. the technology of 3D printers will be widely adopted
C. 3D printers have been in use for at least 100 years
D. engineers and designers prefer printing original products
4. The passage is developed mainly in the form of _______.
A. time and events
B. definition and description
C. contrast and conclusion
D. examples and statements

2016高考模拟题。阅读理解阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。Death Valley is a land of beautiful yet dangerous extremes．Death Valley can be dangerously cold during the winter months． Storms in the mountains can produce sudden flooding on the floor of the Valley．
The air temperature during the summer has been as high as fifty- seven degrees Celsius． The sun can heat the ground so that the temperature of the rocks and soil can be as high as seventy -four degrees Celsius.
Death Valley contains evidence of several ancient volcanoes that caused huge explosions． Evidence
of one of these explosions is called Ubehebe Crater． The explosion left a huge hole in the ground almost a
kilometer and a half wide．
In many areas of Death Valley it is easy to see where the ground has been
pushed up violently by movement deep in the Earth． This movement has created unusual and beautiful
rock formations． Some are red． Others are dark brown, gray, yellow or black．
The area was named by a woman in 1849． Thousands of people from other parts of the country traveled Lo the gold mining areas in California． They Were in a hurry to get there before other people did．One group trying to reach California decided to take a path called the Old Spanish Trail． By December
they had reached Death Valley．They did not have to survive the terrible heat of summer, hut there was
still an extreme lack of water．There were few plants for their work animals to eat．
The people could not find a pass through the call mountains to the west of the Valley, Slowly, they began co suffer from a lack of food．To survive, they killed their work animals for food and began to walk out of the Valley．
As they left, one Woman looked back and said, "Good -bye, death valley． ” The name has never been changed．
Almost everyone who visits Death Valley visits a huge house called Scotty' s Castle．The building design is Spanish, with high thick walls to provide protection from the fierce heat．
The castle is named for Walter Scott , called Scotty． by his friends． He was a gold miner．He told everyone that he built the house with money he made from his gold mine, Many people believed him．But it was not really the truth．
1．The first two paragraphs discuss Death Valley' s
．
A． geography
B． climate
C． location
D． Size
．The woman who named Death Valley intended to
．
A．explore the mystery of the valley
B．find an area with plants for animals
C．experience the terrible heat of summer
D．look for gold in California
．If the passage continues, it will be about
.
A．the truth about Scotty's Castle
B．why Spanish built the castle
C．when the castle was built
D．where the castle lies in1.B段落大意题。根据前两个段主要介绍了死亡谷的温度，暴风和洪水等情况，总之介绍了它的气候。

.A推理判断题。根据最后一段可知下面将些关于Scotty's Castle的真实情况。
A,B,C或D四个选项中，选出最佳选项。
People who are taking aspirin regularly to thin their blood and are about to undergo coronary artery bypass surgery (冠状动脉旁路搭桥术) are usually to stop the aspirin a week before the operation – but they could be better off if they keep taking it.
Taking aspirin up to the day coronary artery bypass grafting (移植) is performed seems to speed lung function recovery afterwards, without increasing the risk of bleeding significantly, according to a report from Israel.
Release of a substance called thromboxane (血栓素) is associated with lung injury after heart bypass grafting, Dr Rabin Gerrah at Assuta Medical Center in Tel Aviv and his colleagues explained in the medical journal Chest. Aspirin is believed to inhibit release of thromboxane, so Gerrah’s group theorized that the administration of aspirin until the day of the surgery could improve outcomes.
They therefore followed 14 patients who took 100 milligrams of aspirin daily until the day of the surgery and 18 who stopped taking aspirin at least 7 days before the surgery.
Those who continued with their aspirin had significantly lower thromboxane in fluid around the heart, better oxygen levels in their blood and spent less time on a ventilator(呼吸器) than the group who discontinued taking aspirin.
On the other hand, the need for blood transfusions was no different between the groups, indicating that bleeding complications were no worse with aspirin.
The researchers had excluded patients who had suffered a heart attack and those with heart failure because patients like these have a higher level of thrombaxane. “They will probably benefit even more than its inhibition.”
Based on their findings, Gerrah’s team recommends that aspirin therapy(治疗) not be discontinued before coronary artery bypass surgery.
1. From the passage we know that_______.
A. doctors usually get people who will have coronary artery bypass surgery to stop taking aspirin 7 days before the operation
B. aspirin is believed to increase release of thromboxane
C. taking aspirin up to the day coronary artery bypass grafting is performed seems to slow lung function recovery afterwards
D. patients suffering a heart attack have a lower level of thromboxane
2. The purpose of the passage is to introduce to us that _________.
A. aspirin can make for release of thromboxane
B. aspirin is useful for patients suffering a heart attack
C. different ways turn out to be the same result
D. aspirin may improve recovery after heart bypass
3. According to Dr Rabin Gerrah, patients who will have heart bypass surgery should _______.
A. stop taking aspirin before the surgery
B. take aspirin as much as they like until the day of the surgery
C. be allowed to take 100 milligrams of aspirin daily until the day of the surgery
D. take aspirin after the heart bypass operation
4. What does the underlined word “inhibit” in paragraph 3 mean?
A. to become larger or better than normal
B. to make something happen more slowly than normal
C. to cause to be nervous or embarrassed
D. to improve something in poor condition
