Within just the last few months, new reports from around the world have been ing in and most agree that our climate situation is much worse than previously thought.At this point, it doesnt matter what is causing it, but rather, what can be done about it.Whats more, our world is getting more and more unstable every year.There is war and threat of war everywhere.Natural disasters are being more frequent and serious.However, other planets are experiencing global warming as well as our own and some scientists believe there may be some connection between this.No one knows anything for sure at this point because there is simply not enough data.【語(yǔ)篇導(dǎo)讀】本文敘述了氣候的變化會(huì)導(dǎo)致的嚴(yán)重后果如：動(dòng)物遷徙、地震和海嘯?，F(xiàn)在導(dǎo)致氣候變化的原因不重要了，重要的是我們應(yīng)該采取措施，應(yīng)對(duì)氣候的變化。1Which of the following would be the best title for the Passage ?AWays to protect our planet.BSolutions to climate change.CBe prepared for climate change.DClimate change and its effects.【解析】標(biāo)題確定題。根據(jù)文章第一句Based on new analysis, we are rapidly approaching major climate change and the effects on society and the environment could be quite severe.關(guān)鍵詞climate change and the effects?！敬鸢浮緿2What is the authors purpose in using the examples of earthquakes?ATo show the damage earthquakes caused.BTo remind people to prevent future earthquakes.CTo show major changes are taking place on the planet.DTo tell us more earthquakes will happen in the future.【解析】細(xì)節(jié)理解題。根據(jù)第三段的第三句The planet itself has been showing signs of change.我們的星球已經(jīng)表現(xiàn)出變化的跡象。【答案】C3What does the underlined word “devastated” in Paragraph 3 mean?ASeparated.BDestroyed.CRemoved.DAffected.【解析】詞義猜測(cè)題。根據(jù)第三段的最后一句Egypt was hit in 2009 with a major earthquake and Haiti was devastated in 2010 by yet another massive earthquake.埃及2009年發(fā)生了大地震，海地2010年有一次遭受了大地震，被地震破壞，摧毀?！敬鸢浮緽4What can be inferred from the Passage?AAnimals and plants wont die out as long as climate changes slowly.BTheres enough data for us to predict the future of climate change.CThe world is getting more unstable because of animal migration.DThe earth is not the only planet that is experiencing climate change.【解析】判斷推理題。根據(jù)最后一段第一句However, other planets are experiencing global warming as well as our own不僅我們的星球而且其他星球都在經(jīng)歷著全球變暖。【答案】DBScientists have discovered thirteen kinds of vitamins.They say vitamins help to carry out chemical changes within cells.If we do not get enough of the vitamins we need in our food, we are at risk of developing a number of diseases.Which foods should be eaten to keep us healthy? Let us look at some important vitamins.Vitamin A helps prevent skin and other tissues from being dry.People who do not get enough vitamin A cannot see well in darkness.Vitamin A is found in fish liver oil and the yellow part of eggs.Vitamin B1 is also called thiamine.Thiamine changes starchy(含淀粉的)foods into energy.Thiamine is found not just in whole grains like brown rice, but also in beans and peas, nuts, and meat and fish.Vitamin B12 is needed so folic acid can do its work.Together, they help produce red blood cells.Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy.Vitamin B12 is found naturally in foods like eggs, meat, fish and milk products.Vitamin B12 is found in green leafy vegetables and other foods, like legumes and citrus fruits (柑橘類水果)Vitamin C is needed for strong bones and teeth.The body stores little vitamin CSo we must get it every day in foods such as citrus fruits, tomatoes and uncooked cabbage.Vitamin D prevents the childrens bone disease rickets (佝僂病)Ultraviolet light from the sun changes a substance in the skin into vitamin DFish liver oil also contains vitamin D.Vitamin K is needed for healthy blood.It thickens the blood around a cut to stop bleeding.It can also be found in pork products, liver and in vegetables like cabbage, kale and spinach (菠菜)Vitamins are important to our health.A lack of required vitamins can lead to health problems.【語(yǔ)篇解讀】本文為大家介紹了維生素的重要性，并列舉了幾類維生素。5What is the main idea of the passage?AThere are thirteen kinds of vitamins in total.BOne can not live without enough vitamins.CVitamins can carry out chemical changes within cells.DEnough vitamins are vital to keep healthy.【解析】主旨大意題。本文為大家介紹了維生素的重要性，并列舉了幾類維生素。故D選項(xiàng)正確。【答案】D6Women who wish to bee mothers should take in _.Avitamin ABvitamin B1Cvitamin B12Dvitamin C【解析】細(xì)節(jié)理解題。根據(jù)第四段Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy.一句，可知答案選C?！敬鸢浮緾7What can change a substance in the skin into vitamin D?AFish liver oil.BUltraviolet light from the sun.CFresh milk drunk by people.DDoing a certain amount of exercise.【解析】推理判斷題。根據(jù)文中Ultraviolet light from the sun changes a substance in the skin into vitamin D可知紫外線可以促進(jìn)維生素D的形成，故答案B正確?！敬鸢浮緽8According to the passage, taking in enough vitamin C can _.Amake our eyesight betterBhelp to stop bleedingCmake our bones and teeth strongDhelp produce red blood cells【解析】推理判斷題。根據(jù)文章Vitamin C is needed for strong bones and teeth.一句可知，答案C正確?！敬鸢浮緾.閱讀填句Its such a mon event that you probably never asked yourself why you sleep._1_In fact, for sleep researchers, its one of the biggest unanswered questions in the field.Stop and think about it for a second.Why should we sleep? _2_ But we sleep every night, even when we have had plenty of rest.There are, no doubt, several different answers to this question, but lets just consider one general purpose of sleep: _3_Human beings are creatures that are normally active during daylight hours, when our senses functions most effectively._4_We cant see objects well, our color vision is entirely lost, and we dont have the smelling or hearing sharpness of other animals.So it actually does make sense to have us stay where we are during the dangerous period when nightwaking animals are walking here and there.And one sure way to make sure we dont fall down everywhere and get lost or eaten is to have us not move for seven or eight hours, rising again only when the light is back and our survival chances are better.Its not the only reason we sleep._5_Perhaps even the most important one.AIs it because we get tired?BShould that put human beings in a terrible situation?CBut from a scientific point of view, this is far from an ordinary matter.DBut in terms of evolution, it may have been one of the first reasons.EFurthermore, if you were designing an animal, would you have it e into long periods of unconsciousness every twentyfour hours?FSleep as a survival approach.GAt night, humans do rather poorly.【答案】15CAFGD
