Let us look at some important vitamins.Vitamin A helps prevent skin and other tissues from becoming dry.People who 4do 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 (柑橘类水果)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 children's bone disease rickets (佝偻病)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.【语篇解读】 本文为大家介绍了维生素的重要性，并列举了几类维生素。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】 主旨大意题。本文为大家介绍了维生素的重要性，并列举了几类维生素。故 D 选项正确。【答案】 D6Women who wish to become mothers should take in _.Avitamin ABvitamin B­1Cvitamin B­12Dvitamin C5【解析】 细节理解题。根据第四段 Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy.一句，可知答案选 C。【答案】 C7What 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】 推理判断题。根据文中 Ultraviolet light from the sun changes a substance in the skin into vitamin D可知紫外线可以促进维生素 D 的形成，故答案B 正确。【答案】 B8According to the passage, taking in enough vitamin C can _.Amake our eyesight better Bhelp to stop bleedingCmake our bones and teeth strong Dhelp produce red blood cells【解析】 推理判断题。根据文章 Vitamin C is needed for strong bones and teeth.一句可知，答案 C 正确。【答案】 C.阅读填句It's such a common event that you probably never asked yourself why you sleep._1_In fact, for sleep researchers, it's 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 let's 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 can't see objects well, our color vision is entirely lost, and we don't 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 don't fall 6down 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.It's 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 come into long periods of unconsciousness every twenty­four hours?FSleep as a survival approach.GAt night, humans do rather poorly.【答案】 15 CAFGD
