Read the article and select the best answer. Article: Greenwich is on the River, five miles from the middle of London, and its history is two thousand years old. The first English people were fishermen there, and they named the place Greenwich, meaning "green village". Later the English kings and queens lived at Greenwich in their beautiful places. The name of the earliest palace was Placentia. Its windows were made of glass--the first in England. But trouble was coming to Greenwich. In 1649, a war started in England and for eleven years there was no king. The men who had worked for him at Placentia decided to live in the place themselves. They sold all its beautiful things, and bought small pieces of the palace garden with money. Finally, the war ended and King Charles II came back. But Placentia was falling down. So King Charles built a new and bigger palace, which is now open to the public. At this time, Charles was worried about losing so many of its ships at sea because their sailors did not know how to tell exactly where they were. So in 1675, Charles made John Flamsteed, the first astronomer in England, try to find the answer. Flamsteed worked in a new building on the high ground in Greenwich Park. From it with a telescope which he made himself, Flamsteed could look all round the sky. And he did, night after night, for twenty years. Carrying on Flamsteed's work a hundred years later, an astronomer called Harrison finally made a clock which told the time at sea, and helped sailors to know where they were.You can see Harrison's clock, still working, in Greenwich's museum of the sea. Because of Flamsteed's work, every country in the world now tells its time by Greenwich time. Question: Who made the first clock which could tell the time at sea? Options: A: Harrison B: Flamsteed C: Henry D: Charles

Article: A new study revealed that the formation of the Earth, Sun and Moon that cause changes in Earth's tides can also trigger a special kind of Earthquake along the California's San Andreas Fault . The study, published in the journal Proceedings of the National Academy of Science,is based on previous researcher suggesting that the gravitational tug of sun and moon is not only affecting the sea levels of Earth, but can also stretch and compress that Earth's crust, producing tremors and quakes. Furthermore, the new study showed that small tremors deep underground were more likely to occur during certain periods of the tidal cycle. For the study, the researchers looked at about 81,000 low-frequency earthquakes from 2008 to 2015 along the Parkfield section of the San Andreas Fault and compared it to the two-week tidal cycle known as the "fortnightly tide," Low-frequency earthquakes are named due to the rumbling sound they make and not by the rate of its occurrence. These kinds of earthquake only occur about 15 to 30 kilometers below ground and are no larger than magnitude 1 in the Richter scale. The researchers discovered that low-frequency earthquakes tend to occur during the waxing period of the tidal cycle, when the tides are getting little by little. It is already known that the strongest Earth tides occur when the sun and moon are in a straight line, while the tide is at its weakest state when the sun and moon are 90 degrees apart. According to the researchers, low-frequency earthquakes show that some part of the San Andreas Fault is creeping, or slowly moving, almost all the time. With the help of the tidal forces, low-frequency earthquakes could provide more information about the deeper part of the fault. "They tell us that the fault continues down below where the regular or typical earthquakes stop on the San Andreas, about 10 or 12 km (about 6 to 7 miles)," said David Shelly, a seismologist at USGS and helped write the study, in a statement. "And they tell us a lot of things about that deep part of the fault... Question: What causes tremors and quakes according to the passage? Options: A: The formation of the Earth, Sun and Moon. B: The change of the sea levels of Earth. C: The effect of the gravitational tug of sun and moon on Earth's crust. D: The movement of creeping in the deep part of the San Andres Fault.

Read the article and select the best answer. Article: I'm Grace, 13 years old and in seventh grade in Florida. This school year has been normal. However, my family and I spent my sixth-grade year driving all over Europe, seeing amazing places, meeting all kinds of people, and getting closer as a family in the process. When my family decided to move to Europe, we were excited . But we had a problem. We couldn't find a vehicle that had enough space to work for our five-member family, so my dad decided he'd just made one. No matter where we were , our new home took some getting used to . I had to leave a lot of my stuff behind because so little of it would fit into my tiny new room. We had to be careful to save our water. And we were doing home school, which worked out great. No matter what, I made sure to look out my window every morning , because the view was different every day -- England, then France, Italy,Greece... each special in its own way. In country after country, we touched around and tried to pick up little bits of the local language, but that didn't help us much. Luckily we kept finding people who knew some English. Everywhere we went , we saw the most amazing things. I love reading about places in my textbooks and then getting out of our vehicle to look right at them . I can't pick a favourite spot, because whichever one we were at seemed to be the best at the time. After our trip ended , we moved to Florida. But it makes me happy that my family had this great year-long experience together. I'm thankful for that. Question: Compared with the seventh-grade school year, Grace's sixth-grade year was _ Options: A: normal B: painful C: unusual D: successful

Article: The Knowledge Society According to American economist Peter Drucker, every few hundred years in Western history a sharp transformation takes place in which society rearranges itself. One such period happened between 1455 and 1517, beginning with the invention of the printing press, and included the Renaissance, the European discovery of America, a reawakening of science, and the Protestant Reformation. All these events had significant effects on the development of Western society. The next period lasted from the American Revolution and the Perfection of the steam engine in 1776 until Napoleon's defeat at Waterloo in 1815. During this time, the Industrial Revolution took place, public schools systems were established on a large scale, the first modern university was founded in Berlin in 1809, and both capitalism and communism emerged as economic and political ideologies. Again, society had been altered.Drucker suggested that another services to them. Question: What is the major characteristic of the new society today ? Options: A: Labor will be the basis of wealth. B: Class conflict will appear. C: Knowledge will be used as an economic resource. D: People who provide various types of services must be socially and economically disadvantaged.
