29、s, which hadnt developed an immunity (免疫力) against it.But there is something more about the new H7N9 bird flu.Unlike the H5N1 bird flu, which causes severe sickness in birds, the H7N9 has been evolving under the radar(悄悄地) since it travels between birds without causing noticeable illness.That makes
30、it difficult to keep track of the disease.The good news is that theres so far no sign that the virus is spreading from person to person.But since there is no vaccine (疫苗) for the disease yet, the World Health Organization recommends that you wash your hands after meeting with sick people and before

57、 _A_ 解析：细节理解题。根据第一项自行车旅行中的“Reserve your spot before availabilityand the cherry blossomsdisappear！”可知，这项自行车旅行需要预订。其他三项自行车旅行都没有提到需要预订。22_D_ 解析：细节理解题。根据第三项自行车旅行中的“Knowledgeable guides will entertain you with the most interesting stories about Presidents，Congress，memorials，and parks.”可知，在Capital City Bi
58、ke Tour中，导游会为你讲述关于总统、国会、纪念碑和公园的最有趣的故事。A项颠倒是非，尽管文中提到总统、国会等，但这只是导游要讲述的故事的主题，并不是说可以见到名人。B项颠倒是非，文中提到导游会讲述关于公园的故事，没有提到参观国家公园。C项无中生有，文中没有提到参观著名博物馆。23 _D_ 解析：细节理解题。由题干中的at night可定位到最后一项自行车旅行。根据最后两句“Tour includes bike，helmet，and bottled water.All riders are equipped with reflective vests and safety lights.”
59、可知，在晚上进行的这项自行车旅行给游客配备了安全灯。A、B、C三项无中生有，文中都没有提到。B篇文章大意：这是一篇记叙文。叙述了亚历山大博士在实验中无意发现一种抗细菌的霉菌盘尼西林(青霉素)的经过。后来霍华德博士把这一发现发扬光大，并使之在二战中发挥巨大作用，挽救了成千上万人的生命。24 _C_.解析：细节理解题。由第一段的“He had been studying some germs(细菌)that he was growing on a plate。They were very dangerous germs because they caused different kinds of
60、illnesses that could kill people.”两句可知亚历山大博士正在对他在培养皿上培养的细菌做实验。C项符合这一意义。A项错在mould上。文中mould是有益的，而不是有害的；B项错在“could cure illnesses”上；D项意思是“他在对不同的能使病人康复的细菌做实验”与原文不符。25_D_.解析：推理判断题。实验中死亡的25只小鼠被注射了毒菌而没注射盘尼西林(penicillin)，青霉素可以杀菌，因而注射了青霉素的小鼠几乎都得以存活。26_C_.解析：细节理解题。由倒数第二段“He found that penicillin was effective
61、 in treating blood poisoning in human beings.”可知答案。27 _D_ 解析：词义猜测题。根据上下文，二战时青霉素供给不足，因此弗洛里博士去了美国帮助制造这种药，这种药的数量应该是D项，意为“巨大的，多的”。后文也证实，这些药救了成千上万人的性命。C篇文章大意：文章介绍了几种克服害羞的方法。28 _B_.解析：细节理解题。根据第二段前三句，尤其是“I was shy”，“My shyness made me focus on me instead of her.”可得知答案是B。29 _C_.解析：细节理解题。根据文章第三段第一句不难得出答案是C。3
62、0 _C_.解析：推理判断题。由第一段中的“Shyness equals losing opportunities，less pleasure and fewer social connections.”并结合作者在第二段中叙述的自己的经历来看，由于害羞，人们会遭受很多痛苦，当然也会不高兴。31 _D_ 解析：细节理解题。根据文章倒数第二段知，作者建议，不要问一些只用“Yes”或“No”来回答的问题。选项A、B、C中的问题都要用Yes或No来回答，所以答案选D。D篇文章大意：本文是一篇说明文。新一波禽流感疫情来袭，你该如何应对？文章就10年前的禽流感与现在的H7N9禽流感情况做了比较介绍，并给
63、人们提出来一些建议。32 _D_ 解析：细节理解题。A项文中没有提及， B项提到的600多人是感染the H5N1 bird flu的人数， 死亡人数为这一人数的60%, 也就是不到400人； 由第三段的“Most of the mutations only affect birds, such as chickens and pigeons, and dont normally spread to humans.”可以推知C项不对； 由第三段的“Any change of the numbers of the two proteins indicates a new mutation(变异)
64、”可推知，H7N9禽流感的名称表明，病毒中的蛋白质发生了新的突变。故选D。33_C_.解析：推理判断题。这里列举SARS的例子是为了说明本段首句谈到的“Any time an animal influenza virus crosses to humans, it is a cause for concern”， 而本段又是进一步说明上一段最后一句话“But once they do, the results can be disastrous.”， 所以C项动物流感病毒一旦传播到人类就会产生可怕的影响为正确答案。故选C。34_D_ 解析：细节理解题。由倒数第二段可知， H7N9禽流感与H5N
65、1禽流感不同的是它不会在禽类间导致明显的疫情，这使得它的传播不容易被及时发现。故选D。35 _C_ 解析：细节理解题。由最后一段可知，专家建议人们勤洗手，尽量避免接触禽类以及禽类下的蛋，所以C项为正确答案。最后一段提到了现在还没有针对H7N9禽流感的疫苗，故a不对。c，d文中没有提及。故选C。七选五：36-40 GBCDA文章大意：这是一篇说明文。主要说明了家庭作业给学生带来的益处：锻炼学生时间管理能力，老师的积极评价帮助学生树立自信等等。同时也指出家庭作业应当适当布置，否则就会变成一种惩罚。36解析：根据前文“Homework is made up of outofclass activit
66、ies and athome activities teachers assign to students.It can include practice assignments that emphasize newly acquired skills.”可知家庭作业由课外活动和教师分配给学生的家庭活动组成。家庭作业可以包括巩固新获得的技能的实践作业。因此下文应为进一步说明家庭作业的类型和作用，上文中的assignments可对应到G项中的assignments，表示：它可以是准备作业，使学生为课堂活动做好准备。符合文意，故选G。37解析：本句位于段首，有总起全段的作用。且根据后文“For e
67、xample，to complete their homework in time，children start dividing their time into studying and playing，thus learning to complete their scheduled tasks within the time they have.”可知为了按时完成作业，孩子们开始把时间分成学习和玩耍，从而学会在有限的时间内完成预定的任务。可知本段是说明家庭作业可以通过锻炼学生的时间管理能力，而使学生受益。故选B。38解析：根据后文“Teachers positive remarks ca
68、n help develop students confidence and encourage them to keep up with their good work.”可知老师的积极评价有助于培养学生的自信心，并鼓励他们跟上好工作的步伐。下文中remarks对应到C选项中comments，指老师对学生做的工作给出评价。上下文连贯通顺，故选C。39解析：根据前文“It provides them with a platform to express what they know or have newly found, and exhibit their talents.”可知家庭作业给他
69、们提供了一个平台，表达他们知道或新发现的东西，展示他们的才华。可知本段是在列举家庭作业带给学生的好处有哪些。根据上下文D项：“It also gives students the practice of whatever they learn in school.”它也让学生练习他们在学校学到的任何东西。符合文意，故选D。40解析：根据上文“The amount and difficulty level of homework assignments should match the ages and abilities of students.”家庭作业的数量和困难度应该与学生的能力和年龄相
70、匹配，故可推测下文是指如果不匹配，家庭作业就会成为一种惩罚。故选A。完形填空:41-45CCBCC 46-50BDACA 51-55DBDCA 56-60BDACB语法填空： 61. argument 62. the 63. saying 64. walking 65. where 66. dangerous 67. immediately 68.to 69.replied 70.However文章大意：一个人和朋友在沙漠中穿行，两人之前发生了争论，这个人打了他的朋友，他的朋友怎么做的呢？他们继续走发现了一个湖，朋友掉到湖里，他把朋友救出来，朋友又是怎么做的呢？61解析：考查名词。由an确定应
71、填名词形式，argue的名词是argument。62解析：考查冠词。hit sb. in the face“打某人的脸”。63解析：考查非谓语动词。without是介词，后跟动名词。64解析：考查非谓语动词。keep on doing“继续做”。65解析：考查定语从句。这是一个非限制性定语从句，先行词是a lake，where引导定语从句，在从句中作状语。66解析：考查形容词。形容词修饰名词situation。67解析：考查副词。修饰动词save应用副词。68解析：考查介词。come back to life“苏醒过来”。69解析：考查动词的时态。根据语境，需用过去时。70解析：考查副词。根据
72、前后句的逻辑关系是转折关系，并且有逗号与后面隔开，故填However。短文改错：Recently I have heard that you feel as a student of Senior Three.Here is some on how to study .First of all，learn in relaxing way.This will remove our pressure，making study an easy job.Another way to keep up with our spirits is to take part in sports.Not onlye
73、xercise build up the body，but also it provides us with time to relax and refresh our mind，helping us memorize things faster and .Music, too， another effective means of refreshing and helping concentrate better.Last but not least, we should exchange ideas with our classmates.Through the communication
74、 we can find support， will encourage us to overcome difficulties in our study.解析：71表示“(人)感到有压力的”应该用过去分词转化的形容词 stressed。72advice是不可数名词，没有复数形式。73副词effectively作状语修饰动词study。74这里说的是“一种放松的方式”，表示泛指概念，故用不定冠词a。75keep up表示“保持(某种状态)”，keep up with表示“跟上，不落后于”。根据语境可知，此处表示“保持饱满的精神”，故with在此处多余。76not only置于句首时，此时句子要
75、用部分倒装，因此在exercise前加助动词does。77与前面的faster呼应，这里应该用比较级longer。78主语是抽象名词music，故谓语动词用单数形式。79与前面的our，us等词呼应，语境表示“帮助我们更好地集中精力”，因此用us。80which引导非限制性定语从句，关系代词在从句中作主语，指代主句内容。that不能引导非限制性定语从句。书面表达参考范文：Dear Mayor， Im Li Hua, a student in Grade Two.Since our city is struggling for National Civilized City, as a resp
