职称英语考试卫生类语法总复习(2)

职称英语考试卫生类语法总复习(2)名词的数：重点应了解和掌握以下内容：1、名词的可数和不可数：与汉语不同，英语中名词要区分可数与不可数。

笼统地讲，物质名词，如：water(水), iron(铁), wood(木头)等, 和抽象名词，如：democracy(民主), freedom(自由), happiness(幸福)等为不可数。

不可数名词前不能加a (an)，后面不能加s (es)，这是考试中对此类题目判断的重要依据。

2、以下名词为不可数名词：news(消息) information(信息)furniture (家具) equipment(设备)advice (劝告) weather(天气)work*(工作) clothing(衣服)baggage(行李)work作“工作” 解释时为不可数名词，”找工作”不能说to find a work, 应为to find a job; work作”着作”、”作品”解时是可数名词，如：Deng Xiaopin’s works (邓小平着作)/ a work about Deng Xiaopin (一件关于邓小平的作品);作“工厂” 解释时，单复数同形：a steel works (一个钢铁厂) / two chemical works(两家化工厂) 实例：We have a large staff but there ______ in the office.A. haven’t many furnituresB. aren’t many furnituresC. hasn’t much furnitu reD. isn’t enough furniture解题思路：根据名词数的概念A、B肯定错，不必考虑;C、D的主要差异是”hasn’t”与“isn’t”, 句子中有there，说明该句是there be句型，故正确答案为D.题中staff, office 等词与解题无关。

Health officials have warned that a high caffeine intake could affect birth weight or the chance of having a miscarriage , pregnant women are advised against drinking more than four cups of coffee a day-or six cups of tea.3 the study ,by the university of Aarhus inDenmark ,recruited more than 1,000women before they were 20 week’s pregnant, who drank at le ast three cups of coffee a day. The group was split into two, with 568 women drinking ordinary instant coffee and 629 drinking decaffeinated. The authors then monitored the birth weight of 1,150 newborn babies and the length of pregnancy for the babies.4 the study, published by the British Medical Journal, found “no significant difference” between the two groupsfor birth weight or length of pregnancy. The researchers concluded that a moderate reduction in caffeine intake in the second half of pregnancy had “no effect” on the outcome.5 the women were not told what type of coffee they were drinking ,and the research was adjusted to take into account factors such as age, weight and whether the women smoked.When the adjustments were made, the average weight of babies born to women in the decaffeinated group was a mere 16g higher than those born to women in the caffeinated group, the study said. The average difference in the length of pregnancy was less than two days.6 A spokeman for the British Coffee Associationsaid：”this new study is very interesting and supports the consistent advice given that pregnant women should stick to a safe upper limit- in line with guidance issued by the Food Standards Agency.

2020 年职称英语考试卫生类概括大意(3)The Safeness of IUDs for HIV-positive Women1. Women infected with the most common form of HIV may safely use the intrauterine device (IUD)for contraception, provided they see a doctor regularly, new study findings suggest.2. World Health Organization guidelines currently state that, in general, HIV-infected women should avoid IUDs. “Those guidelines were essentially made on theoretical concerns, and there are really very little data on what contraceptive is appropriate for HIV- infected women,3 ” saidthe lead author Dr. Charles S. Morrison in North Carolina4.3. Morrison and colleagues gathered information on IUD- related complications at 1, 4 and 24 months after placement of the device in 636 women living in Nairobi, Kenya5. Of these women, 156 had HIV infection. Participating physicians did not know the patients ' HIV status. There was “littledifference in any side effects in HIV-infected women compared with HIV-uninfected women, suggesting that the IUD is likely an appropriate method for HIV- infected women, ” Morrison said. “This is an important issue, because there are now 16 million women living with HIV and a lot of them have a critical need for contraception, ” he added.4. The researchers did find6 that women with infections such as gonorrhea or chlamydia at the study 's outset were at increased risk of IUD complications, confirming current guidelines suggesting that women with sexually transmitted diseases not use IUDs.75. In addition, there was no difference in the amount of virus theHIV-positive women were releasing from their cervix, or shedding8, at thebeginning of the study compared with 4 months after the IUD was inserted, the researchers reported in the August issue of the British Journal of Obstetrics and Gynaecology. Conversely, some studies have shown a relationship between increased cervical HIV shedding and the use of oral contraceptives.6. “What this study suggests is that you need to avoid IUD use in women with a cervical infection but not women with HIVinfection, ”Morrison said. “ Women with cervical infections are at increased risk of complications ：women with HIV infection are not. ”词汇：intrauterine 子宫内的outset 开头，最初contraception 节育，避孕cervix . 颈，宫颈(pl. cervices 或cervixes) contraceptive 避孕的; n. 避孕工具，避孕药物shedding 脱落物complication 并发症妇科学obstetrics 产科学gonorrhea 淋病gyn(a)ecologychlamydia 衣原体(pl. chlamydiae) cervical 颈的（如宫颈的）注释：1.IUD = IUCD ( 为intrauterine contraceptive device 的首字母缩写）：宫内节育器2.

2020职称英语考试卫生类概括大意专项训练题（3）Science FictionAmongst the most popular books being written today are those which are usually classified as science fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore,some of the most successful films of recent years have been based on science fiction stories.It is often thought that science fiction is a fairly new development in literature,but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society,a theme which is still often found in modern stories.Most of the classics of science fiction,however,have been written within the last hundred years. Books by writers such as Jules Verne and H.G. Wells,to mention just two well-known authors,have been translated into many languages.Modern science fiction writers don't write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind； or in imagining future worlds which are a reflection of the world which we live in now. Because of this their writing has obvious political undertones.In an age where science fact frequently overtakes science fiction,the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going,however,may provide a valuablelesson on how to deal with the problems which society will inevitably face as it tries to master its new technology.1.

2020职称英语考试卫生类语法(3)

2020职称英语考试卫生类语法(3)分词1. 分词作定语1)分词作定语既能够放在所修饰的词之前，作前置定语，也能够放在所修饰的词后面，作后置定语。

其作用相当于一个定语从句。

例如：Where are the reserved seats?(=Where are the seats which have been reserved?)预定的座位在哪里?This is a pressing problem.(=This is a problem which is pressing.)这是一个紧迫的问题。

2)分词作后置定语可分为限制性(紧跟在所修饰的中心词之后)和非限制性(用逗号与其所修饰的中心词分开)两种，其作用分别相当于一个限制性定语从句和非限制性定语从句。

例如：The funds raised(= which have been raised)are mainly used for helping the homeless.筹集的资金主要用来协助那些无家可归的人。

There are many students waiting(= who are waiting)to get examined.有很多学生在等待检查。

This book,written(= which is written)in simple English,is suitable for beginners.本书是用浅显的英语写的，适合初学者。

3)分词常和形容词、副词或名词构成合成形容词作定语。

例如：The flower-carrying girl must be waiting for someone.那位手持鲜花的姑娘一定在等人。

The newly-built building is our office building.这座新建的大楼是我们的办公楼。

4)有些不及物动词的过去分词作定语，并不表示被动的意思而是表示完成。

这类过去分词常作前置修饰语。

2020年职称英语考试卫生类语法(3)

2020年职称英语考试卫生类语法(3)(12) special与especial的区别：表示事件不同寻常、过度或特殊时，两个词可互换，但special较为常用。

另外，special还能够表示特别的目的。

如： She pays (e)special attention toclothes.(她非常注重着装) / These are special chairs for small children.(这些是专门给小孩子的椅子)(13)gone、lost、missing的区别：gone表示“丢了，没了”，含一去不复返的意思，也能够表示“死了”，作表语或宾补，不能够作定语;lost表示“丢失”，含难以找回的意思，可作定语、表语或宾补;missing表示“失踪了，不见了”，强调某人物不在原处，可作定语、表语或宾补。

如：My fever(高烧) is gone， but I still have a cough.(发烧消退了，但我仍然咳嗽) / The parents found thelost child at last.(家长终于找到了迷路的孩子) / My dictionary is missing.Who’s taken it away?(我的字典不见了，谁拿走了?) / For more detailed information(详情) of the missing girls，please visit our website(网址).(如果想知道失踪女孩们的详情，请访问我们的网站)(14) living、alive、live、lively的区别：四个词都来源于动词live“生活、居住”。

living读[‘l iviN]有三个意思：①“活着的、现存的”，作表语或定语，②“一模一样的、逼真的”，③相当于lively，意思是“强烈的、活泼的”;live读[laiv]，指东西“活的”，能够替换为living;alive读[[‘laiv]作表语，指人“活着的”，如果作定语，则放在名词的后面;lively读[‘laivli]有三个意思：①有生气的、活泼的、快活的，②(色彩)鲜艳的，③生动的、真实的。

2020年职称英语考试卫生类语法(2)

2020年职称英语考试卫生类语法(2)(5) such用法： such + a(n) + 名词(单数)(+that从句)。

如：I have never seen such a foolish(愚蠢的) boy.(我从来没有见过这么蠢的男孩) / He had such a terrible accident that he could never forget it.(他遭遇了这么可怕的事故,他永远也不会忘记)(6) good与well：表示“好”时,作定语或表语用good,作状语用well;表示“(身体)好”时用well.如：Doing sports is good for us.(实行运动对我们有益) / Study well and make progress every day.(好好学习,天天向上) / --How are you?―I am very well.(你好吗?我很好。

)(7) nice与fine：的区别：nice表示令人愉快的,能够指东西、人物外表等;fine一般指身体或天气好。

如：Let’s go and share(分享) the nice cake.(我们去分享那块美味的蛋糕吧) / She is anice girl.(他是个漂亮的姑娘) / What a fine day!(多好的天气!)/He’s fine recently(最近).(近来他身体不错)(8) too much与much too：too much表示“太多的”,修饰事物数量;much too表示“太过,过度”,修饰形容词或副词。

如：I amfull because I have had too much rice.(我饱了,因为我吃了太多的米饭) / That coat is much too dear.(那件大衣太贵了)(9) quick、fast与soon：quick与fast基本同义,quick往往指反应速度快,fast往往指运动速度快,而soon则表示时间上很快即将发生。
