A．Evidences． B．Facts． C．Faults． D．Failures． 答案： C　词义猜测题。根据第一段“A new study has found no evidence that sunscreen， commonly used to reduce the risk of skin cancer， actually increases the risk．(一项新的研究发现，没有证据表明常用来降低患皮肤癌风险的防晒霜实际上会增加患皮肤癌的风险。)”，同时结合画线词所在句子中的“studies that had reported associations between sunscreen use and higher risk of melanoma(研究认为使用防晒霜会有较高风险患黑素瘤)”可知，以前的研究结论是存在错误的，因此flaw意为“错误”，故选C。 答案 课后课时作业(五) 2．What can we know about people with fair skin and freckles? A．They seldom use sunscreen． B．They are more in danger of skin cancer． C．They can be free from the harm of the sun． D．They often expose themselves to the sun． 答案： B　细节理解题。根据第五段中的“people with fair skin and freckles (雀斑)， for example—are more likely to use sunscreen． As a result， it may appear that sunscreen users get cancer more often (例如，皮肤白皙、有雀斑的人更倾向于使用防晒霜。因此，使用防晒霜的人更容易患癌症)”可知，白皮肤和有雀斑的人更有可能得皮肤癌，故选B。 答案 课后课时作业(五) 3．What can we learn from the passage? A．Sunscreen users get skin cancer more often． B．The volunteers have proved the effect of sunscreen． C．The new study was based on the experiences of volunteers． D．The number of skin cancer patients is increasing in America． 答案： D　细节理解题。根据第三段可知，大多数健康专家认为，防晒霜通过保护皮肤免受太阳的有害影响，有助于预防皮肤癌。在美国，皮肤癌的发病率增长速度比其他任何癌症都要快。由此可知，美国的皮肤癌的病人数量在增加，故选D。 答案 课后课时作业(五) 4．Which of the following can be the best title for this passage? A．Sunscreen to Prevent Skin Cancer B．Sunscreen to Increase Skin Cancer C．Skin Cancer Caused by Sunscreen D．Skin Cancer Caused by Freckles 答案： A　标题判断题。根据第一段并结合全文谈论防晒霜与皮肤癌的关系，并从最新的研究中证明防晒霜可以帮助预防皮肤癌可知，A项(预防皮肤癌症的防晒霜)最适合作文章标题，故选A。 答案 课后课时作业(五) B On January 7th， 2022， David Bennett became the first person to have a heart transplanted successfully into him from a pig． On that occasion， mere operation success was the goal． This operation is a milestone for xenotransplantation (异种移植)—the transfer of organs from other species to human patients． 课后课时作业(五) For decades， researchers have attempted to deal with xenotransplantation's basic problem． This is that the human body， when it recognizes foreign tissue， tends to turn against it． In the case of pigs， the most important marker of foreignness is a sugar molecule (分子) called alpha­Gal． While this molecule does not exist in humans， antibodies to kill it do． So no transplant from a pig with alpha­Gal would last more than a couple of minutes in a human body． In 2003 pigs were produced with a changed genome so as to prevent the enzyme (酶) responsible for making alpha­Gal． This was a step in the right direction， but other barriers popped up． 课后课时作业(五) The pig for David's operation had a genome changed in ten ways to increase the chances of success． Three genes had been removed to reduce the risk of a human antibody rejecting the organ． A fourth， a growth gene， had also been knocked out， to ensure the heart did not enlarge after transplantation． And six human genes had been added to promote acceptance． There are other concerns． One is any unknown rejection mechanism． Another is the possibility that the organ may pass viruses to its new host． The pig in question was raised where there was no virus to reduce the chance of that， but it remains a possibility． 课后课时作业(五) In theory， pigs can be raised to provide humans with any solid organ， but some will be more complex than others． Moreover， even if these barriers can be overcome， most researchers still acknowledge that increasing xenotransplantation to meet the world's demand for organs may take decades． After this news， however， the chances that it will happen eventually have increased． 篇章导读：本文是一篇新闻报道。文章报道了全球首例异种移植手术成功，David Bennett (大卫·贝内特)成为第一个从猪身上成功移植心脏的人。 篇章导读 课后课时作业(五) 5．What is the basic problem of xenotransplantation? A．The human body lacks alpha­Gal． B．The human body resists foreign tissues． C．The life of the transplanted organ is too short． D．The enzyme is prevented from making alpha­Gal． 答案：B　细节理解题。根据第二段中的“For decades， researchers have attempted to ... tends to turn against it．”可知，异种移植的基本障碍是人体排斥外来组织。故选B。 答案 课后课时作业(五) 6．Why was a growth gene removed in David's case? A．Because it would change David's genome． B．Because it would lead to heart enlargement． C．Because it would make the heart more acceptable． D．Because it would be recognized by David's antibodies． 答案：B　细节理解题。根据第三段中的“A fourth， a growth gene ... enlarge after transplantation．”可知，移除生长基因是为了确保移植后心脏不会扩大。故选B。 答案 课后课时作业(五) 7．What can we learn about the pig? A．It saved the patient's life perfectly． B．It had a decreased number of genes． C．It had an unknown rejection mechanism． D．It was raised in a virus­free environment． 答案：D　细节理解题。根据倒数第二段中的“The pig in question ... it remains a possibility．”可知，为了减少感染的可能性，那头猪是在没有病毒的地方饲养的。故选D。 答案 课后课时作业(五) 8．What is the author's attitude towards the future of xenotransplantation? A．Optimistic． B．Indifferent． C．Disturbed． D．Uncertain． 答案：A　推理判断题。根据最后一段中的“Moreover， even if these barriers ... eventually have increased．”可知，作者认为，这次异种移植手术的成功，表明未来异种移植以满足世界对器官的需求的可能性增加了。由此可推知，作者对异种移植的未来持乐观态度。故选A。 答案 课后课时作业(五) Ⅱ　语法填空 Many kinds of music can stir the imagination and produce strong feeling． For some people， romantic composers such __1__ Chopin increase feelings of love and sympathy． Religious and spiritual music can help some people feel peace． __2__ one musician seems to have a unique ability of healing the human body—Wolfgang Amadeus Mozart． Scientists __3__ (find) Mozart's music to be remarkable in its ability __4__ (calm) its listeners． It can also help them express themselves more clearly． 课后课时作业(五) Many amazing cases have been documented using Mozart as a healing aid． For example， a tiny baby __5__ (name) Kissy， who weighed just 1．5 pounds at birth， was on total life support． Doctors thought she had little chance of survival． Her mother insisted __6__ playing Mozart for Kissy， and thought it saved her daughter's life． Kissy lived， but she was very small for her age and __7__ (slow) than the average child． At the age of four， she showed __8__ interest in music and her parents gave her violin lessons． 课后课时作业(五) To their __9__ (astonish)， Kissy was able to play musical pieces from memory that were far beyond the ability of an average four­year­old． __10__ (play) music helped her improve in all areas of her life． 1． ________　2． ________　3． ________　4． ________　5． ________　 6． ________　7． ________　8． ________　9． ________　10． ________ 篇章导读：本文是一篇记叙文。一个出生即病危的小女孩，父母坚持为她播放莫扎特的音乐，孩子活了下来，并在四岁时展现出对音乐的极大兴趣。 篇章导读 课后课时作业(五) 1．as　考查固定搭配。such as “比如；例如”。故填as。 2．But　考查连词。前面提到很多音乐家演奏的音乐能影响人的精神，这里指莫扎特的音乐却能治愈人身体的疾病。与上文形成转折，应用连词but；位于句首首字母大写。故填But。 3．find/have found　考查动词的时态和主谓一致。此处find这个动作已经完成并对现在造成影响，应用现在完成时；又可用一般现在时表述事实；主语scientists为复数。故填find/have found。 4．to calm　考查非谓语动词。ability to do sth意为“做某事的能力”，此处应用动词不定式作后置定语。故填to calm。 答案 课后课时作业(五) 5．named　考查非谓语动词。name作动词，意为“命名，起名字”，在句中作后置定语修饰名词baby，与name之间为被动关系，应用过去分词。故填named。 6．on　考查介词。insist on doing sth意为“坚持做某事”。故填on。 7．slower　考查形容词的比较级。根据下文than the average child可知，此处应用形容词的比较级。故填slower。 答案 课后课时作业(五) 8．an　考查冠词。show an interest in ... 意为“表现出一种对……的兴趣”。故填an。 9．astonishment　考查词性转换。to one's astonishment意为“令某人感到惊诧的是”。故填astonishment。 10．Playing　考查非谓语动词。句意：演奏音乐帮助她在生活的各个方面都有所提高。此处应用动名词作主语；位于句首首字母大写。故填Playing。 答案 课后课时作业(五) Ⅲ　应用文写作 假设你是李华，针对当前学生的近视问题，你代表学生会发出“保护眼睛”的倡议。内容包括： 1．目前学生的近视现状； 2．保护眼睛的具体措施； 3．呼吁同学们保护眼睛。 注意：1．写作词数应为80左右； 2．可以适当增加细节，以使行文连贯； 3．开头和结尾已经给出，不计入总词数。 参考词汇：近视 myopia/short­sightedness 课后课时作业(五) Dear fellow students， ﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍﹍ Student Union 课后课时作业(五) [精彩范文] Dear fellow students， Faced with heavy academic arrangements， we have to bury ourselves in study for a long time, which makes our vision gradually decline． Considering its seriousness， I put forward the following initiatives on behalf of the Student Union． In the first place， take advantage of the reasonable schedule that can reduce excessive use of eyes． If so， our eyes won’t be in a fatigue condition． In addition， put regular eye exercises into a good habit． They can relax our eyes， thus reducing the chance of myopia． Above all， stay away from the Internet or mobile phones as far as possible． Otherwise， it will cause short­sightedness easily． 答案 课后课时作业(五) Eyes are the windows of our mind． With them， our life becomes colorful． Please take action immediately to cherish， love， and protect our eyes． Student Union 答案 课后课时作业(五) R $$
