Read the following article and select the best answer. Article: "Earthquake!"The word flashed in my brain.A roaring sound filled my ears.I tried to slide beneath my desk.The desk did a wild tap dance,slipping and sliding towards the centre of the room.I twisted my body and grabbed at the windowsill behind me,somehow kicking free of my dancing chair.I tried to stand.My legs skated away as if on a bucking escalator. My fingers shook,grasped and held the windowsill tightly.Somewhere through the roar sounded the terrified scream of some wounded animal.I looked behind me and tried to steady my gaze on the other kids but the scene was a dizzy nightmare.Some of the class were sitting in the middle of the room,surrounded by chairs and desks.One girl was screaming.A boy was trying to claw his way across the floor to the door in a crazy overarm crawl. My grip froze me to the windowsill. I cried aloud,"I'm going to die.I'm going to die.Save me,I'm not ready to die,I'm not ready!" I hunched forward on my knees and pressed my face against my clenched fingers.I looked at the backs of my fingers and stupidly noticed the fragile pale hairs growing out of the pores.The fingers would soon cease to exist.Somehow the impending horror of my death was too terrible to even cry about. Suddenly,I became aware that the rocking had ceased.Perhaps I wasn't going to die. Question: The roaring sound was made by _ . - a wounded animal - people screaming - children running - an earthquake
an earthquake

Read the following article and select the best answer. Article: Humans have observed and explored the oceans since ancient times.But it wasn't until the 19th century that the scientific study of oceans began.The first major scientific expedition,and the one that firmly established the field of oceanography,was the around-the-world voyage of H.M.S. Challenger.Setting out from England in 1872,the Challenger spent almost three and a half years gathering a wealth of information about seawater,sea life,and the ocean floor.Major oceanographic expeditions since then have included the South Atlantic voyage of the German ship Meteor in 1926 and the Deep-Sea Drilling Project from 1968 to 1983.Many individuals also have played important roles in advancing our understanding of oceans,beginning with Matthew Fontaine Maury in the mid-1800s;his work on oceanography and navigation led to a uniform system of weather reporting at sea.Since Maury's time,oceanography has progressed rapidly.Early oceanographers had to contend themselves with tossing buckets overboard to see what they might haul in.Today's oceanographers are equipped with space images,supercomputer models,and deep-sea robots that can crawl along the seafloor.As they set goals for the future,some oceanographers even dream of doing research in permanently manned stations on the bottom of the oceans. Question: Which of the following statements is true? - Humans didn't explore the oceans until the 19th century. - Maury first established the field of oceanography. - Maury spent a lot of time in studying seawater,sea life,and the bottom of the ocean. - Many individuals also plays a very important part in advancing our understanding of oceans,such as Maury.

Q: Read the following article and select the best answer. Article: When prehistoric man arrived in new parts of the world, something strong happened to the large animals; they suddenly became extinct. Smaller species survived; the large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans. That the seas are being over-fished has been known for years and researchers such as Ransom Myers and Boris Worm have shown how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) inanes fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then. Dr. Worm acknowledges that these figures are conservative . One reason for this is that fishing technology has improved. Today's vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around noise. Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the date support an idea current among marine... Question: Dr Myers and other researchers hold that _ . - people should look for a baseline that can't work for a longer time - fisheries should keep the yield below 50% of the biomass - the ocean biomass should restore its original level. - people should adjust the fishing baseline to changing situation.
A: people should adjust the fishing baseline to changing situation.

Read the following article and select the best answer. Article: Do you know that many clowns go to school to learn how to be funny? How would you like to go to that school? You could learn how to walk and talk like a clown. Then you could make people laugh. Clowns may go to school for a year. There they learn to move in funny ways. They learn to run and jump like different animals. They also learn how to fall down in a special way. They make sure they don't get injured. They make every move look easy. But really it's hard work. In a school clowns decide how they will look. They make funny pants and tops. Then clowns have their funny long shoes made. They also learn to make up their faces. Clowns carefully put special paint on, so they look silly. They start by making every part of their feces white. Then they use red paint around their mouths to make them look big. Clowns may paint re spots on each side of their faces, too. Big red noses are added. They put on funny hair or funny hats. Now they look silly. They are ready to go to work! You can see clowns at the circus or parade. They do funny things to surprise people. Ten big clowns may get out of a very small car. Or they may walk on a high rope. Then they almost fall. The faces they make when they try to stand up again make people laugh. Question: Which of the following is NOT mentioned in the passage? - Clowns learn to be funny at school to make people laugh - Clowns wear strange pants and tops and funny long shoes. - Clowns don't feel frightened when they walk on a high rope. - Clowns put on funny hair and hats and make faces
Clowns don't feel frightened when they walk on a high rope.
