But man was limited by what he could see with his eyes alone. The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens. Each new tool added to the field of astronomy helped man reach out into space. They did not know that the planet called Saturn had rings around it. Their sight was so limited that they could not see all the planets. In the early 1700s, people thought there were only six planets. Nepture , the last of eight planets to be discovered, was not seen until 1846. Before the spectroscope , man did not know what kind of gases was in the sun or other stars. Without the radio telescope, we didn't know that radio noises came from far out in space. Today, astronomy is a growing science. We had learned more in the last fifty years than in the whole history of astronomy. Question: . Until there were _ , man knew very little about the moon. Options: A: telescopes B: spectroscopes C: radio telescopes D: spaceships

Read the article and select the best answer. Article: When I decided to write the story of my early years growing up in poverty, many of my friends and family members were shocked. They were more interested in my story of success, such as how I was able to create the nation's largest firm for millions of dollars. That's the story everyone wanted me to write, but it's not the story I wanted to tell. Looking back, I see so clearly how often, throughout my boyhood, I was touched by random acts of kindness that helped shape me into the man I am today. And random acts of violence and ignorance played just a powerful lawyer involves hard work, bur escaping generational poverty is the hardest thing I ever done. I chose to write the story of my childhood years in poverty, with the hope that a child somewhere in the world will read my story and be inspired to break the cycle of poverty. My publisher was quick to point out that the market would be small for a memoir written by a ly unknown author. To everyone's surprise, the book received over 1,000 pre-publication orders one month before the scheduled launch date. The book launch scheduled for October 1, was moved up to September 14. Less than four months later, the first print run of 5,000 copies were sold out. Today, the memoir is being used by universities, high schools and middle schools, as a case study of the behavior patterns of the culture of poverty as well as valuable lessons on how to succeed in life. Here is a quote from the principal of a middle school in Texas on October 27, who is using my memoir for students 5th through 8th grades; "We are halfway through your story. It is changing the lives of our students and the perspectives of our teachers. Question: In the author's opinion, he wrote his memoir mainly for _ . Options: A: children living in poverty. B: students all over the world. C: employees in law firms and banks. D: successful people in all circles.

Q: Read the article and select the best answer. Article: A group of soldiers were stationed in the country near the home of a big landowner, called Lord Hunt. As they wanted to stay on good terms with the landowner, they offered to blow up a large tree _ that had remained after part of a tree had been blown down in the storm. But Lord Hunt asked them not to damage the plantation of young trees that was next to the stump. The officer in charge of the engineers promised him that they would be careful. Lord Hunt was so pleased that he asked the whole group to lunch on the day of the explosion. The day came and just before lunch, the officer checked with one of his men to see if they had put enough explosive in the stump. "I checked the maths," said the soldier "and it comes to 32 kilos." "Are you sure?" asked the officer. "Perhaps you'd better put in a bit more just to make sure." The lunch continued and everyone ate a lot and drank a lot. A little later, the group of soldiers went outside with Lord Hunt to see the explosion. "You just see, Lord Hunt, that tree will fall in exactly the right place without hurting any of your young trees," said the officer. The soldier lit the fuse, then walked quickly away to take cover. After a minute the tree, instead of falling over on its side, rose with the explosion 20 metres into the air, taking with it a huge quantity of earth together with all the young plantation. "Sorry sir, I made a mistake!" said the soldier. "It should have been 3.2 kilos, not 32 kilos." Lord Hunt was so upset that he turned around and walked back to his house. He looked at the house in horror and saw that every single window had been broken by the explosion. He was so upset that he went to the toilet on the ground floor to get over his feelings of shock. When he had finished, he pulled the plug of the toilet and the whole ceiling, which had been weakened by the explosion, fell on his head. Question: When the explosion came, it _ . Options: A: destroyed the tree without harming the plantation B: blew up the tree but left the stump C: was stronger than expected D: blew up the tree in the expected direction

*Question*
Read the article and select the best answer. Article: Which is safer --- staying at home, traveling to work on public transport, or working at the office? Surprisingly, each of these carries the same risk, which is very low.However, what about flying compared to working in the chemical industry? Unfortunately, the former is 65 times riskier than the latter! In fact the accident rate of workers in the chemical industry is less than that of almost any of human activity, and almost as safe as staying at home. The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby.It is this that makes chemical accidents so newsworthy.Fortunately, they are extremely rare.The most famous ones happened at Texas City (1947), Flixborough (1974), Seveso (1976), Pemex (1984) and Bhopal (1984). Some of these are always in the minds of the people even though the loss of life was small.No one died at Seveso, and only 28 workers at Flixborough.The worst accident of all was Bhopal, where up to 3,000 were killed.The Texas City explosion of fertilizer killed 552.The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives, just a month before the unfortunate event at Bhopal. Some experts have discussed these accidents and used each accident to illustrate a particular danger.Thus the Texas City was caused by tons of ammonium nitrate, which is safe unless stored in a great quantity.The Flixborough fireball was the fault of management, which took risks to keep production going during essential repairs.The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep.When the poisonous gas drifted over the town , local leaders were incapable of taking effective action.The Pemex fire was made worse by an overloaded site in an overcrowded suburb.The fire set off a chain reaction of exploding storage tanks.Yet, by a miracle, the two largest tanks did not explode.Had these caught fire, then 3,000 strong rescue team and fire fighters would all have died. Question: Which of the following statements is TRUE? Options: A: Working at the office is safer than staying at home. B: Travelling to work on public transport is safer than working at the office. C: Staying at home is safer than working in the chemical industry. D: Working in the chemical industry is safer than traveling by air.
