Q: Read the following article and select the best answer. Article: Robots are being used for the first time in hospitals. "Robot-nurses" perform a variety of tasks such as delivering medicine, food and laboratory samples to sickrooms and taking away waste. Patients aren't treated by robots, as this is still done by medical staff. The idea is to employ robots to transport supplies between departments. "Nurses often have to break off from what they are doing to gather supplies," says Peter Seiff, who makes the robots called TUGs. Research shows any interruption in medical work can lead to errors --- a nurse may forget whether she has given medicine and may give a patient double the dose or none at all. The robots vary in size according to what job they perform, but normally take the shape of a metal box on wheels, with a box on the side containing their software. After being programmed, the robots are able to find their way around a hospital unassisted. They also contain scanning technology to create electronic pictures or a "memory" of routes on their hard drives to help them go through passages, doors and other obstacles. Each robot is also monitored at the producer's headquarters in case it runs into any difficulties. Trials show TUGs reduce the time it takes for a patient to receive medicine, and stop drugs from going missing. A study at the University of Maryland Medical Centre in the U.S. found that when three TUGs were used over the course of a year, the average length of time from the drugstore receiving a prescription to the patient receiving it dropped from 74 minutes to 30 minutes and saved nurses 6,123 hours finding medicines. It also cut the number of medicines that went missing to zero. "The biggest complaints we receive from patients is that the nurses don't spend enough time with them. Anything that frees nurses is a _ ," says Katherine Mulligan, director of nursing at the hospital, "The TUGs allow nurses to spend more time focusing on patient care. Nurse satisfaction has improved." Question: Which of the following is TRUE according to the passage? - Robots can help nurses save a lot of time. - All robots have the same size. - Robots are unable to find their way by themselves. - Robots cannot get help if they run into difficulties.
A: Robots can help nurses save a lot of time.

Q: Read the following article and select the best answer. Article: Johann Gutenberg, who worked as a goldsmith , took what had already been discovered, and created a small invention that changed history. He created a machine that allowed him to move small blocks of letters in such a way that written material could be printed and mass-produced. Few people could read before Guttenberg made the invention, but once books became less expensive, more Europeans could read and write. Block printing existed long before Gutenberg. The Chinese had been using wood blocks to print books as early as 868, but a new set of woodcuts had to be made for each book. Producing one book was not easy; producing all kinds of books was more difficult. Writing ink dates from about 2500 BC in Egypt and China. Gutenberg used an oil-based printing ink that would last longer than other inks used in his time. We don't know much about Gutenberg because he was not famous during his lifetime. He was born in Germany about 1400. In 1448, Gutenberg developed signatures for each number, letter, and punctuation mark . He then built the molds to hold the signatures in place. Gutenberg published the first mass-produced book: a 1,282 page Bible. To this day, more copies of the Bible have been printed than any other book. Copies of Gutenberg's invention spread throughout Europe, but the German goldsmith did not get rich from his invention. Some officials _ the invention of printing because they feared that it would spread bad ideas. By 1500 there were 1,700 printing presses in Europe. The presses had already produced about 20 million volumes of 40,000 different books. Question: Compared with block printing in China, Johann Gutenberg's method _ . - was difficult to run - needed harder paper - used a new kind of ink - was put into use earlier
A: used a new kind of ink

Q: Read the following article and select the best answer. Article: My husband and I were once in Nepal to see sunrise over the Himalayas. One morning we awoke to total darkness at 5 o'clock.As we rushed through a town with cameras in hand,I noticed the calm,gentle way the Nepalese people greeted the morning.One man boiled a huge pot of milk tea,and other villagers gathered around his fire,cupping their hands around small glasses of the steaming sweet mixture.It was fascinating,but not to be left behind,we joined the stream of tourists moving quickly up to the lookout point. The top was crowded when we arrived,but after 10 minutes of cold waiting,the assembled group gave up."The cloud cover is too heavy,"one said.Then one by one they rushed down the hill to the next item on their sightseeing list.I was disappointed as well,but suddenly I noticed a small Nepalese boy absently playing with a stick and shooting quick glances at the clouds.He must know something we don't,I thought.I decided to wait with him. The boy and I didn't have to wait long.Moments later,a tiny stream of golden light burned through one thick cloud,then another.Rose-colored fog warmed the backs of the clouds,and suddenly the morning sun stole a glance around the side of the mountain,mile above where I'd expected it to be. Nothing I'd seen before prepared me for the moment the clouds withdrew with bowed heads,and the magnificent Himalayas were revealed before,around,and above me.I sat in astonishment,not breathing,not daring to look away,certain that God had placed me here at the backdoor of Earth to show me what Heaven really looks like.I certainly got the message.Never again will I rush a sunrise.I now know Nature will supply her fruits to me only when I am truly ready to receive them. Question: What can be concluded from the passage? - Do in Rome as the Romans do. - God helps those who help themselves. - Time and tide wait for no man. - Fortune rewards those having patience.
A: Fortune rewards those having patience.

Q: Read the following article and select the best answer. Article: In the second half of each year, many powerful storms are born in the tropical Atlantic and Caribbean seas. Of these, only about half a dozen becomes the strong, circling winds of 75 miles per hour or more that are called hurricanes, and several usually make their way to the coast. There they cause millions of dollars of damage, and bring death to large numbers of people. The great storms that hit the coast start as soft circling wind hundreds -- even thousands -- of miles out to sea. As they travel aimlessly over water warmed by the summer sun, they are carried westward by the southeast winds. When conditions are just right, warm, moist air flows in at the bottom of such a wind, moves upward through it and comes out at the top. In the process , the moisture in this warm air produces rain, and with it the heat is changed to energy in the form of strong winds. As the heat increases, the young hurricane begins to move in a counter-clockwise motion . The life of a hurricane is only about nine days, but it contains almost more power than we can imagine. The energy in the heat released by a hurricane's rainfall in a single day would satisfy the entire electrical needs of the United States for more than six months. Water, not wind, is the main source of death and destruction in a hurricane. A typical hurricane brings 6 to 12 inch downpours, causing sudden floods. Worst of all is the powerful movement of the sea -- the mountains of water moving toward the hurricane center. The water level rises as much as 15 feet above normal as it moves toward shore. Question: When is an ordinary tropical storm called a hurricane? - When it begins in the Atlantic and Caribbean seas. - When it hits the coastline. - When it is more than 75 miles wide. - When its winds reach 75 miles per hour.
A: When its winds reach 75 miles per hour.
