Question: Article: The 9.2magnitude earthquake which caused the tsunami in the Indian Ocean on Boxing Day last year occurred at 7:58 a.m.,95 miles off the west coast of Aceh, Indonesia. Eighteen minutes later.10-metre high waves crashed the ashore along a 500----mile-long stretch of Aceh. Two hours later the tsunami hit Thailand and Malaysia and then Burma, Bangladesh, India,the Maldives,Sri Lanka,Kenya and Somalia.The final death toll is thought to be about 280,000,with tens of thousands more listed as missing.More than l.8 million people lost their homes. *What Is Tsunami? A tsunami is a chain of fast moving waves caused by a sudden strong quake in the ocean.They can be caused by earthquakes,volcanic eruptions ,or even the collision of meteorites .Tsunamis are also incorrectly known as tidal waves,but unlike tidal waves they are not caused by changes in the tides. They are also most common around the edge of the Pacific,where more than half of the world's volcanoes are found.These fast moving waves can attack coastlines,often with little or no warning.Rocks weighing as much as 20 metric tonnes have been pulled from sea walls and carried l 80m inland. *Wave Power Atsunami can have a wavelength in excess of 1 00km and there may be an hour between them.They travel at great speeds across an ocean with hardly any energy losses and are barely noticeable out at sea. Over the deep Pacific Ocean,a tsunami travels at about 800kph.If an earthquake happened in Los Angeles.a tsunami could hit Tokyo quicker than you could fly between the cities by jet. *Strange Animal Behaviors Ten days before giant waves slammed into Sri Lanka and India coastlines,wild and domestic animals seemed to know what was about to happen and fled to safety. Elephants screamed and ran for higher ground. Dogs refused to go outdoors. Zoo animals rushed into their shelters and could not be enticed to come back out.
Question: ..What does the first part of the passage mainly tell us?
Options: (A) The great speed of a tsunami. (B) The number of deaths caused by a tsunami. (C) The countries which were struck by a tsunami. (D) The serious destruction caused by the great power of a tsunaml.

Answer: D

Question: Article: Dan Bebber is a senior research fellow at the University of Exeter in Britain. He says research has shown that wild plants and animals are moving toward Earth's North and South poles as the planet warms. Mr Bebber wanted to know if the same thing was happening with organisms that attack agricultural crops. He examined reports of first sightings of new insects and diseases around the world. The records came from CABI - the Centre for Agricultural Bioscience International. He says the group began collecting information from developing and industrialized countries years ago. Dan Bebber and his research team studied 612 different organisms - from viruses and bacteria to insects like beetles and butterflies. They found that since 1960, crop pests and diseases have been moving toward the poles at an average rate of about 3 kilometers each year. Mr Bebber says this puts the most productive farmland in the world in danger. "As new species of pests and diseases evolve and potentially the environment for them becomes more _ at higher latitudes, the pressure on the breadbaskets of the world is going to increase." Farmers face other threats. Invasive species passed through trade are also causing problems. Gene Kritsky is an Entomologist at the College of Mount St. Joseph in Ohio. He specialises in the study of insects. He says climate change may improve conditions for some invasive species. "It means that species in other parts of the world that might do well in warmer temperatures can now do well in the breadbasket of America." Another Entomologist Christian Krupke of Purdue University says the effects of these changes will depend very much on the crop, the insect and the disease. But he says the research is a warning sign that people should care about climate change and do something about it.
Question: The purpose of Dan Bebber's research was to find _ .
Options: (A) if farmland could be moved to colder places thanks to global warming (B) if diseases and insects harmful to crops were going towards colder areas (C) if organisms were moving to the north and south poles (D) if the number of crop pests was increasing

Answer: B

Question: Article: Don't you find that it is getting increasingly darker every day when you wake up for school ? As winter comes ,days become shorter while the nights become longer ,In the past people slept more in winter ,but in modern times we just use more electric light instead of sunlight to continue our normal routines . But scientific research is finding that manhandling of electric light is making us sick . Electric light is fooling the body's biological clock into releasing awaking hormones ( )at the wrong times ,scientists say .This might be leading to seasonal fatigue and depression . Much more than mental health is at stake ,Recent scientific studies have found that women who work at night ,have higher chances of getting breast-cancer . "Electric lights are wonderful ,but as with a lot of other things ,we really mess ,things up "said David Avery ,a psychiatrist ." Our ancestors evolved in a very regular light -dark cycle ,and our bodies just work better that way ." Researchers have known for a long time that all living things have a biological clock that is linked to light ,Being of the natural day-night cycle can cause fatigue ,mood change and depression ,This is known as seasonal affective disorder ,or SAD. Scientists disagree on the cause of SAD ,Some say it is caused by winter's late sunrises , others blame the early sunsets . However ,they all agree the perfect solution to SAD is to give up artificial light ,It will quickly bring someone into a cycle of long ,restful nights and easy awakenings at dawn . But realistically most people need to use electric light in their everyday life . Ironically the next best solution is to use more bright lights to reset the body's biological clock . By getting bright light first thing in the morning it simulates an earlier dawn and shifts the body clock forward ,according to Alfred Lewy ,a psychiatrist at Oregon Health & Science University . A 2005 study done by the American Psychiatric Association showed that daily exposure to bright light was about as effective as medicine used to treat several forms of depression .
Question: According to the text ,electric light is bad for health mainly because _
Options: (A) is shortens people's sleeping time (B) it makes people upset and unable to concentrate (C) it releases radiation and increases people's chances of getting sick (D) it stimulates the body to release awaking hormones at the wrong time

Answer:
D
