8、 have an impact on research into human health. Zebra fish are quickly becoming the animal of choice for many researchers. “After mice，they are the most commonly used vertebrates，that is，animals with backbones，in genetic studies，”says Jose Cibelli，the leader of the team.“They are used in cancer and

9、 heart-disease research because they have many of the same genes as people have.” For more than 20 years，zebra fish have also served as an excellent model for understanding both normal development and birth imperfections.More recently，research with zebra fish has extended to modeling human diseases

10、. Traditional cloning uses an egg and a donor(捐贈(zèng)者) cell.The DNA is removed from the egg and replaced by the DNA taken from the donor.The resulting fish is an exact genetic copy of the donor.In Cibelli's technique，the egg is removed from the female zebra fish and placed in the ovarian(卵巢的) fluid of

11、a Chinook salmon，another kind of fish，before the donor cell is placed into the egg.The previous methods of cloning zebra fish had very low survival rates.With the new technique，the number of cloned fish is increased by 15 percent. What makes zebra fish so useful in research is that their eggs are t

12、ransparent(透明的)，making the fish's development easy to follow. Improving zebra-fish cloning techniques is also important because currently the mouse is the only good model for genetic research. “So far the mouse is the only animal from which you can delete genes in a reliable way，”Cibelli says.“Wha

13、t researchers do is mutate(使變異) a gene，destroy its function completely，and then study the consequences.” 1. What do we learn about zebra fish from the text? A．They can be used to cure human diseases. B．They have been used in genetic studies for 20 years. C．They are the only vertebrates used in c

15、 infer the following from the text EXCEPT that ________. A．the zebra fish cloning technology may provide a new model for genetic research B．mice will not be used in genetic research any more C．experimental results on zebra fish may apply to human beings D．Jose Cibelli led the new research of clo

17、ucing fat intake would be the surest way to greater health.In fact，there is such a thing as too little fat.Strange but true：eating without fat can lead to vitamin deficiencies(維生素缺乏癥)．That's because some vitamins require fat to be taken into the body and to do their jobs，which include providing ene

18、rgy，keeping the body working normally and supporting the body to fight against disease，for a start.Vitamins are necessary，which means fats are necessary，too. Dietary fat，which comes from the food you eat，is crucial to the intake of the vitamins soluble(可溶的)in fat，which includes vitamins A，D，E and

19、K．(Vitamin C，needed for healthy teeth，doesn't need fat) Among them，vitamin A is necessary for good eyesight，and vitamin D for bone health. When vitamins which are soluble in fat are taken in，they move from the mouth to the stomach and then to the small intestine(小腸)．Fats can move across the cell w

20、alls(細(xì)胞壁) of the small intestine and enter the body's general movement of blood.Any vitamins in that fat are taken into the body as well.The vitamins are then carried to the liver(肝臟)，where they're stored until the body needs them. Without enough fat in your diet，your body cannot successfully take

21、in the fat-soluble vitamins that are necessary to your health.However，the types of fat you eat matter a lot.There are some important rules to follow，including：avoid unhealthy fats and plant fats are best.Besides，eat healthy oils.Last but not least，don't overdo it.You only need a small amount of fat

22、 to help take in vitamins.Just a little with any vitamin-rich meal and it'll get those vitamins into position to do some good. 5．The first paragraph mainly talks about ________. A．why low-fat products are popular B．the best way to stay healthy C．the importance of different vitamins D．the impo

27、動(dòng)詞。 2．A　resist doing sth.為固定搭配，意為“抵制做某事，忍住不做某事”，再結(jié)合關(guān)鍵詞funny可知A項(xiàng)符合題意。 3．A　考查名詞詞義。in good condition意為“狀況良好”。atmosphere“氣氛”；case“情況”；situation“形勢(shì)”。 4．D　考查介詞短語(yǔ)。at one time“曾經(jīng)”；all the time“始終”；at a time“每次”；from time to time“有時(shí)”。由句意可知D項(xiàng)正確。 5．D　考查形容詞詞義辨析。available “可用的”；comfortable“舒服的”；convenient“方便

28、的”；reasonable“合理的，講道理的”。由句意可知D項(xiàng)正確。 6．C　根據(jù)“The work we have done has brought great benefits.”可知我們所做的工作帶來(lái)了很大的成效，所以我們的努力沒有白費(fèi)?！癷n vain”意為“徒勞，白費(fèi)力氣”，符合題意。 7．C　考查with的復(fù)合結(jié)構(gòu)用法。with＋名詞＋形容詞/分詞，在句中作狀語(yǔ)，表示謂語(yǔ)動(dòng)作發(fā)生的伴隨情況、時(shí)間、原因、方式等。 8．C　merely意為“僅；只；不過(guò)”。certainly一定，必定，當(dāng)然；hardly幾乎不；nearly差不多，幾乎。根據(jù)否定回答可知C項(xiàng)正確。 9．D　“t

29、hat the new school building be built next month”為同位語(yǔ)從句，解釋說(shuō)明名詞decision的內(nèi)容。 10．D　對(duì)話上句句意：對(duì)于明天的全國(guó)英語(yǔ)演講比賽我感到非常緊張。四個(gè)選項(xiàng)的意思分別是：A項(xiàng)“我真羨慕你”，B項(xiàng)“聽到這件事很高興”，C項(xiàng)“聽起來(lái)不錯(cuò)”，D項(xiàng)“別緊張”。由題中的關(guān)鍵信息nervous可知D項(xiàng)符合題意。 Ⅲ.1.D　根據(jù)第五段最后的“...the number of cloned fish is increased by 15 percent.”可以知道，這種新的克隆技術(shù)可以大大提高克隆斑馬魚的成活率。 2．D　根據(jù)第六段的“

30、What makes zebra fish so useful in research is that their eggs are transparent，making the fish's development easy to follow.”可知人們之所以選擇斑馬魚進(jìn)行基因研究是因?yàn)樗麄兊穆咽峭该鞯?，利于觀察。 3．B　根據(jù)最后一段的“‘So far the mouse is the only animal from which you can delete genes in a reliable way，’Cibelli says.”可以推知B項(xiàng)不正確。 4．B　通讀全文可以知

31、道，作者是在介紹一種比較新的克隆斑馬魚的研究，因此B項(xiàng)符合題意。 5．D　本段主要介紹了脂肪的重要作用。 6．A　根據(jù)第一段的“Strange but true：eating without fat can lead to vitamin deficiencies.That's because some vitamins require fat to be taken into the body...”可知，有些只溶于脂肪類的維生素只有在脂肪存在時(shí)才能被人體吸收，所以脂肪攝入不足會(huì)導(dǎo)致維生素缺乏癥。 7．D　根據(jù)第二段的“...the vitamins soluble in fat，wh

32、ich includes vitamins A，D，E and K．..and vitamin D for bone health.”可知，維生素A，D，E和K都是脂溶類維生素，無(wú)脂類食物可能導(dǎo)致這些維生素缺乏，而維生素D會(huì)對(duì)人的骨骼起重要作用。 8．B　根據(jù)最后一段“There are some important rules to follow，including：avoid unhealthy fats and plant fats are best.Besides，eat healthy oils.Last but not least，don't overdo it.”可知，

33、在攝取脂肪的問題上，文中共給出三種建議，即“避免攝入不健康的脂肪”、“食用健康的油類”以及“不要過(guò)量攝入脂肪”。 Ⅳ.1.I'm sorry to bother you，but can you tell me the way to the railway station？　2.You've done so much work that you're bound to pass the exam.　3.She is overweight，but she can't resist eating more delicious food.　4.I was struck by her youth and enthusiasm.　5.On no condition shall we give in to any difficulty.
