Ques:While only about 200 astronauts have had the excitement of looking down at Earth and commanding systems on the International Space Station, actually thousands of everyday middleschool students have experienced by Middle School Students, or EarthKAM, a camera system. EarthKAM is an educational activity and outreach investigation that also results in remote Earth sensing and observation. Using the Internet, the students control a special digital camera fixed aboard the space station, enabling them to photograph the Earth's coastlines, mountain ranges and other geographic items of interest from the unique advantage point of space. While EarthKAM offers a powerful way for students to investigate Earth from the unique perspective of space, it is also inspiring the next generation of flight controllers for space programs--involving university students to control and operate the camera system and related activities from the ground. In the interview, Brion Au, one of the investigation developers at NASA's Johnson Space Centre, said,"EarthKAM is a payload by students, for students. They are in charge. This system provides a viewpoint that the astronauts have...it's just aweinspiring!"So far, students have captured more than 40,000 photos of the Earth from the space station as it orbited the Earth once every 90 minutes, traveling at 17,500 miles an hour. The team at EarthKAM posts these photographs online for the public and participating classrooms around the world to view. Au explains that this education investigation is inspiring students to explore the world by examining Earth, while promoting social studies, art, geography, science, technology, and math, among other important lessons involving research and teamwork. EarthKAM was started by Dr. Sally Ride, originally flying on the shuttles. The camera is located in the window Observational Research Facility, also known as the WORF, one of many the station's research facilities. What doesn't belong to the next generation of flight controllers for space programs? A) University students' controlling the camera system. B) University students' operating the camera system. C) University students' related activities from the ground. D) University students' investigating Earth from space.

Ques:In August 2015, President Obama announced that North America's highest mountain, Mount McKinley, would be renamed. Its new moniker , Denali, was actually its original Aleut name, meaning "the high one". The previous name, on the other hand, only dates back to 1896--the year when it was named in honour of William McKinley(1843--1901), who was shortly to become President of the United States. Denali is of course not the only mountain with an interesting linguistic history, so let's travel to Asia, and across Europe, to explore the naming of those continents' most famous peaks and mountain ranges. The Nepalese name Himalaya comes from a Sanskrit word meaning "Abode of Snow", from hima for "snow" and alaya for "abode". In Buddhist sources, Himalaya is known by various names such as Himava and Himavanta. In 1856, Mount Everest was named after Sir George Everest (1790--1866), who was the superintendent  of the Trigonometrical Survey of India. Everest himself was initially displeased by the naming, since he feared that local inhabitants might not be able to pronounce it. K2 stands for Karakoram 2, because it was the second peak to be surveyed in the Trigonometrical Survey in the Karakoram system. It was also formerly known as Mount Godwin Austen after Col. H. H. Godwin Austen, who first surveyed it. Another alternative name for the mountain is Chhogori. Annapurna is a household Goddess for Hindus, who guarantees to her worshippers  that food will not fail. The name derives from a Sanskrit word meaning "one who gives nourishment". The Matterhorn's name derives from the name of the nearby town of Zermatt, the second element of which is apparently Matte "meadow", and Horn, "horn". Horn is not an unusual element in German names of mountains with jutting peaks. The mountain is called Mont Cervin in French and Monte Cervino in Italian, from the Italian adjective cervino "deer-like", which conjures up  a deer's antlers. Ben Nevis is the Anglicized form of the Scottish Gaelic name Beinn Nibheis, which means"Mountain by... How many continents' mountains are mentioned in the passage? A) 2 B) 3 C) 4 D) 5

Ques:When someone says, "Well, I guess I'll have to go to face the music", it does not mean he is planning to go to a concert. It is something far less pleasant, like being called in by your boss to explain why you did this or that, and why you did not do this or that. Sour(; )music, indeed, but it has to be faced. The phrase "to face the music" is familiar to every American, young and old. It is at least 100 years old. Where did the expression come from? The first information comes from the American writer James Fennimore Cooper. He said in 1851 that the expression was first used by actors while waiting in the wings to go on stage. After they got their cue(,) to go on, they often said, "It's time to go to face the music." And that is exactly what they did--- face the orchestra   which was just below the stage. An actor might be frightened or nervous as he moved on to the stage in front of the audience that might be friendly or perhaps unfriendly especially if he forgot his lines. But he had to go out. So, "to face the music" came to mean having to go through something, no matter how unpleasant the experience might be, because you knew you had no choice. The other explanation comes from the army. Men had to face inspection by their leader. The soldiers worried about how well they looked. Was their equipment clean--shiny enough to pass inspection? Still, the men had to go out, and face the music of the band, as well as the inspection. What else could they do? The passage is mainly about  _  . A) the meaning of the phrase 'to face the music" B) how to deal with something unpleasant C) how to learn English phrase D) how to go through difficulty
