一般现在时，动词单数第三人称系动词现在进行时，现在分词一般将来时动名词
一般现在时：表示现在经常反复发生的动作、存在的状态或习惯性的动作的时态。可概括为①经常性或习惯性动作；②长期存在的特征或状态；③普遍真理、客观事实等。构成：一般现在时用行为动词的原形，但第三人称单数作主语时，动词的词尾要加-S。a. 表示经常性或习惯性的动作。&例：Li Ming always helps the old man. 李明一直帮助这位老人。&We usually go to school on foot. 我们通常步行上学。&They sometimes go fishing on Sundays. 他们有时周日去钓鱼。 b. 表示永恒不变的事实或真理。&例：A bird flies with wings. 鸟用翅膀飞翔。 c. 用在格言、谚语中。&例：Pride goes before a fall. 骄者必败。&一般现在时具体用法:1.表示经常的或习惯性的动作，常与表示频率的时间状语连用。时间状语：always，usually，every morning/night/evening/day/week/year，often，sometimes，occasionally，from time to time，twice a week，rarely,seldom，once a month，hardly，ever,never.e.g： I leave home for school at 7:00 every morning.2.表示主语具备的性格、能力、特征和状态。e.g：I don't want so much.Ann Wang writes good English but does not speak well.比较：Now I put the sugar in the cup.I am doing my homework now.3.表示客观事实和普遍真理。e.g ：The earth moves around the sun.Shanghai lives in the east of China.4.在时间状语从句和条件状语从句中，常用一般现在时代替将来时。5.表示预先计划或安排好的行为。6.小说故事用一般现在时代替一般过去时。新闻报道类的内容，为了体现其“新鲜”性，也用一般现在时来表示过去发生的事情。7.有些表示状态和感觉的动词表示现在发生的具体行为时，只用一般现在时，而不用进行时态。8.表示现在发生的具体动作或存在的状态9表示格言或警句中。　e.g Pride goes before a fall.　骄者必败。注意：此用法如果出现在宾语从句中，即使主句是过去时，从句谓语也要用一般现在时。例：Columbus proved that the earth is round.. 第一句用一般现在时，用于操作演示或指导说明的示范性动作，表示言行的瞬间动作。再如：Now watch me,I switch on the current and stand back.第二句中的now是进行时的标志，表示正在进行的动作的客观状况，所以后句用一般现在时。一般现在时用法表:&
第三人称单数的构成见下表：
第三人称单数
work(工作)stop(停止)
worksstops
以-ch, -sh, s, x, o结尾
teach(教)wash(洗)dress(装扮)fix(安装)go(去)
teacheswashesdressesfixesgoes
以“辅音字母+y”结尾
变y为i，再加es
fly(飞翔)try(尝试)
fliestries不规则变化have和be动词 变have为has 变be为am,is,are例: have- be-am,is,are一般现在时的特殊用法:一些动词可用一般现在时来表达现在进行时：verbs of the senses: hear,see,taste,smell，feelverbs of the thinking: believe,know,mean,realize,think,rememberverbs of the linking: dislike,fear,heat,like,love,wantverbs of the possession: belong,have,own,possess系动词：亦称连系动词，作为系动词，它本身有词义，但不能单独用作谓语，后边必须跟表语，亦称补语（形容词），构成系表结构说明主语的状况、性质、特征等情况。be（是）是最基本的系动词。小学涉及到的系动词需要掌握的am, is, are&如：I am from Beijing. 我来自北京。&My mother is a teacher. 我的妈妈是一位老师。&除了系动词be，常用的系动词还有look（看起来）、sound（听起来）、feel（感觉到）、become（变成）、smell（闻起来）等。 例：The boy looks very happy. 这个男孩看起来很高兴。&&&&&&&& The dish smells good. 这盘菜闻起来很香。 be动词意思和用法:一般的意思是：是，此种用法，有多种变化形式，is，am，are，was，were，being，been，to be.另外，be动词还有成为的意思。根据句子中不同的人称、数和时态，应该选择相应的be动词。
要看句语的时态:
如果是一般过去时,就用was/were
如果是一般现在时,就用am/is/are
如果是一般将来时,就用will be
然后看主语的人称及复数形式:
一般过去时：
第一人称和第三人称的单数形式，则用was
第一人称和第二人称、第三人称的复数，则用were
一般现在时：
第一人称单数形式，用am
第三人称单数形式，用is
第一人称复数、第二人称、第三人称的复数形式，则用are
一般将来时：
一般时态有关be动词的口诀：
我用am，你用are，is连接他/她/它，复数形式就用are
be动词的用法：现在时 I am, you are, he is, we are, you are, they are （缩略式 I'm, you're, he's, we're, you're, they're），（否定缩略式 I'm not, isn't, aren't），过去时 I was, you were, he was, we were, you were, they were （过去时否定缩略式 wasn't, weren't），过去分词been,现在分词being英语的“be”是个特殊动词；有些语言，如马来文等，并没有“be”这样的动词。“Be”除了原形的“be”之外，还有另外七种形式：am, is, are, been, being, was, were.在句子中，“be”可以是主动词(The Principal Verb)或助动词(The Auxiliary Verb)系动词Be(am, is, are&)的用法：一、口诀：我用am，你用are，is连着他，她，它；单数名词用is，复数名词全用are；变疑问，往前提，句末问号某丢弃；变否定，更容易，be后莫忘记；疑问否定任你变，句首大写莫迟疑。二、Be动词在一般过去时中的变化：1、am和is在一般过去时中变为was；2、are在一般过去时中变为were3、带有was或were的句子，其否定、疑问的变化和am is are一样，即否定句在was或were后加 not，一般疑问句把was或were调到句首。现在进行时：表示动作发生的时间是“现在”，动作目前的状态是“正在进行中”。所谓“正在进行中”，是指在谈到这件事的时候，这个动作还在进行中。现在进行时由“系动词am/ is/ are+动词-ing形式”构成。&例：We are reading the text. 我们正在读课文。&&&&&My sister is working in a hospital. 我的妹妹在医院工作。&&&&&They are watching TV now. 他们正在看电视。&&&&&What are you doing, Li Lei? 你现在正在干什么，李雷？ 现在进行时的基本用法：A表示现在( 指说话人说话时) 正在发生的事情。例：We are waiting for you.B. 表示现阶段正在进行的动作，说话时未必正在进行。例：Mr. Green is writing another novel.(说话时并未在写，只处于写作的状态。)例：She is learning piano under Mr. Smith.C.已经确定或安排好的但不确定会不会发生的将来活动。I'm leaving for a trek in Nepal next week.（我下周要去尼泊尔旅行)We're flying to Paris tomorrow.(我们明天乘飞机去巴黎）一般现在时与现在进行时的区别：一、准确理解两种时态的主要含义：（一）一般现在时：1.表示事物的本质特性或客观存在，没有时限性。The table ____ soft。（feels) 表特性特征。Japan ___ in the east of China。　 (lives) 表客观事实2.现阶段经常性、习惯性的行为，可带频率时间。The shop closes at 7:30 p.m.Father doesn’t smoke. （习惯）3.表说话时的状态，感觉或结果，一般用状态动词，如：It doesn’t matter. Does it hurt? （感觉结果）4.特殊用法：－在条件、时间、让步从句中用现在时代替将来。－If you go there,I’ll help you.—用在begin,come,go,leave,return,open,close 等短暂谓语动词表规定计划。The plane takes off at 11:30. （不受主观支配的计划）－在剧本、解说、标题或there(here）开头的句中表进行There goes the bell/Here comes Mr.Wang.I declare the meeting opens.（正在宣布）He meets the ball and hits back to No.2 （正在发生）（二）现在进行时：1.说话时正在发生，进行的动作Look! Dark clouds are gathering . （正在发生）2.表现阶段正在进行，但此刻不一定正在进行的事。He usually gets up at 6:00,but this week he is getting up at 7:00. （现阶段正在进行，但说话时不一定在起床）3.现在进行时的特殊意义－表示主观打算常用于 go,come,leave,start,begin 等，位移、趋向动词。How long are you staying here （准备停留）－表示眼前刚过去的语意即“话音刚落”，适用于tell,say,talk,discuss ….You don’t believe it You know I’m telling the truth.－表示安慰、关心、喜欢、讨厌等感情色彩。He is always making noises in class. （讨厌）－在条件、时间、让步状语从句中表示将来正在进行。Don’t bother him if he is reading this time tomorrow.
二、严格区分进行时与一般时的语义1.持续动词的一般时表持续情况，经常性，习惯性行为或客观存在的事实，进行时表暂时性或有限时刻的持续。2.短暂动词的一般时叙述事实，特征，能力而短暂动作进行时描述反复发生，即将发生或刚开始行为。3.短暂动词和静态动词一般时表示实际情况客观状态、结果、特征、特性，进行时表未完成含开始或渐进之意。The bus stops. （车停了－事实）The bus is stopping. （渐渐停下来）I love the job. （静态事实）I am loving the job. ( 渐渐爱上了）4.come,go,leave,start,return,move,reach,sail,fall 等一般时态表客观规定计划，进行时表主观打算推测。Flight 254 leaves at 5:30. （表客观规定计划）The plane is taking off an hour later.（主观判断）5.现在进行时带always,continually, constantly, for ever等频率副词表感情色彩，一般现在时则没有此用法。现在进行时的构成是：主语+be+v.ing〔现在分词〕形式
现在分词的构成：
goingwalking
以不发音字母e结尾
去e，再加ing
writingcoming
以重读闭音节结尾，且末尾只有一个辅以字母
双写词尾+ing
runningcutting
以ie结尾的重读闭音节
变ie为y+ing
dyinglying
结尾为c且c读作/k/时
在结尾加k再加ing
picnicking一般将来时：表示将来某个时间要发生的动作或存在的状态，也表示将来经常或反复发生的动作。 由“助动词will+动词原形”构成。“be going to+动词原形”结构是将来时的另一种形式，表示将要发生的事或者事先经过考虑打算去做某事。 例：We will go to Shanghai next year. 明年我们要去上海。&&&&&& &&We are going to have a football match tomorrow. 我们明天要举行一场足球比赛。&&&&&& & Tom is going to have a bath. 汤姆要去洗澡了。 一般将来时常见结构:1、will / shall + 动词原形（否定句在will/shall后加not）will 常简略为 'll，并与主语连写在一起，如： I'll，she'll,he'll，it'll，we'll，you'll，they'll。一般疑问句如用will you…？其简略答语须是Yes，I will或 No，I won't；如用 Shall I…？（较少见）其简略答语须是 Yes，I shall．或 No， I shall not．这种方法一般单纯地表示将来某个时间将要发生的动作或存在的状态。will用于各种人称;shall只用于第一人称。 例如 :I will / shall go to visit him next week. 下周我将去拜访他。What time shall we go there tomorrow? 明天我们几点去那儿?2、be going to 动词原形be going to 相当于一个助动词(其中be有人称和数的变化),与它后面的动词原形一起构成谓语。用来表示近期将要发生的动作以及计划、安排和打算要做的事。例如:There is going to be a football match this afternoon.今天下午将有一场足球赛。I‘m going to go to the park. 我将要去公园。常用结构:1、用于"I expect, I'm sure, I think, I wonder宾语从句"中。Don't worry about the exam. I'm sure you'll pass.不要担心这次考试，我确信你会通过的。2、用于祈使句和陈述句中。Work hard and you will succeed.如果你努力，就会成功的。3、与表示时间或条件的状语从句连用。I'll let you know as soon as he arrives.他一到我就通知你。be going to与will的区别:be going to与will两者都可表示将要发生的事、将要去做某事，但它们有如下几点区别：1. be going to 表示近期、将要发生的事情，will 表示的将来的时间则较远一些，如：He is going to write a letter tonight.He will write a book one day.2. be going to 表示根据主观判断将来肯定发生的事情，will表示客观上将来势必发生的事情。He is seriously ill. He is going to die.He will be twenty years old.3. be going to 含有“计划，准备”的意思，而 will 则没有这个意思，如：She is going to lend us her book.He will be here in half an hour.4.在有条件从句的主句中，一般不用 be going to, 而多用will, 如：If any beasts comes at you, I'll stay with you and help you注意be going to和will在含义和用法上稍有不同。be going to往往表示事先经过考虑的打算；will多表示意愿，决心。两者有时不能互换。如：She is studying hard and is going to try for the exams.她正努力学习并尝试参加考试。（is going to不能用will替换）一般将来时一般用法:（1）一般将来时表示将要发生的动作或情况。例如：I will(shall) arrive tomorrow.我明天到。（主语是第一人称时最好用shall）Will you be free tonight? 你今晚有空吗？We won’t (shan’t) be busy this evening. 我们今晚不忙。（2）在一般将来时的句子中，有时有表示将来时间的状语，有时没有时间状语，这时要从意思上判断是否指未来的动作或情况。例如：Will she come? 她（会）来吗？（3）在以第一人称I或we作主语的问句中，一般使用助动词shall，这时或是征求对方的意见，或是询问一个情况(b)：a. Where shall we meet? 我们在哪儿碰头？b. Shall we have any classes tomorrow?明天我们有课吗？在这类问句中，近几年来也有不少人用will，特别是在美国。例如：How will I get there? 我怎么去？（4）be going to+ 动词原形a.表示计划、打算、准备做的事。例如：We are going to put up a building here.我们打算在这里盖一座楼。How are you going to spend your holidays?假期你准备怎样过？b.表示即将发生或肯定要发生的事。例如：I think it is going to snow. 我看要下雪了。常用时间状语:1）tomorrow,the day after tomorrow,tomorrow morning/afternoon/evening2）next year/week/month/hour/day/century3）in+一段时间4)in the future5)this afternoon/Sunday/evening6)from now on7)one day,someday （未来的）某天8)soon动名词：如果一个动词加上了-ing变成了名词，那么这个词称动名词。 动名词是一种兼有动词和名词特征的非限定动词。它可以支配宾语，也能被副词修饰。动名词有时态和语态的变化。 例：Reading is an art. 读书是一种艺术。&Swimming is a good sport in summer. 游泳是夏天一项好的运动。&There is no saying when he'll come. 很难说他何时回来。&No smoking. (=No smoking is allowed here) . 禁止吸烟！&No parking. 禁止停车！&Let’s go shopping. 让我们去购物。 &动名词常见题型:1）动名词做主语时，谓语动词为单数2）在动名词和不定式中，作为介词的宾语是动名词3）动名词的否定直接在其前加否定词，通过代词的宾格或所有格形式给出逻辑主语例：I would appreciate_______ back this afternoon.A．you to call B．you call C．you calling D．you’re calling（Key：C；换成your calling也对）4）有些词后只能接动名词 can’ understand...5）另外还有一些接-ing形式的常用说法it’ it’s no/little/hardly any/ it’s not/hardly/ it’ spend money/ there’ there’ there’ what’s the use/point...6）有些词后面加不定式和动名词均可remember,forget,try,stop,go on,continue,stop,regret,cease,mean后面均可用不定式和-ing形式，但意义截然不容。例：remember to do/doing：①I remembered to post the letters.（指未来/过去未来将要做的动作）②I remembered posting/having posted the letters.（我记得做过这个动作）forget与remember的用法类似。regret的用法：①I regret to inform you that…（我很遗憾地通知你……）②I regretted having left the firm after twenty years.（为了“二十年前的离开”而遗憾。）try to（努力）与try +–ing（试验）：①You really must try to overcome your shyness.②Try practicing five hours a day.
动名词用法口诀：动名词常泛指，句法作用宾/表/定与主，时态/语态之形式，一般/完成/被动式。Being done 系被动，不含任何进行意。用作主语请留意，常用it作形式主语，不指未来发生事，表达的信息系已知。用作表语请记清，作用相当一名词，检验方法很简单，主与表换位能成立。用作定语也易辩，表示名词之用途。用作宾语稍复杂，关键留意谓语动词（跟动名词作宾语的常用动词附后），时态同谓动作比较，先于谓动用完成式，其逻辑主语不固定，在句中/句外均有之。否定式其前加not，复合式其前加物主词，非句首宾格词也可用，尤其口语中更如此。说明：1、主-----主语 2、宾-----宾语 3、表------表语 4、定------定语 5、谓动---谓语动词

A research and development () department is responsible for innovations in design, products, and style. This department is responsible for creating innovative new products to keep companies a step ahead of the competition. Many companies also rely on the R&D department to improve existing consumer products, and to explore new ways of producing them.
Companies thrive and succeed by creating innovative products, as well as by increasing company profit and utilizing cost-efficient methods. A research and development department is primarily responsible for ensuring that these goals are met. This is an especially important function in the fields of manufacturing and pharmaceuticals, but can be applied to virtually any industry.
Often, research and development works closely with the marketing department. Marketing studies consumer trends by surveying and researching consumer demands, purchasing methods, product sales, and the existence and development of technology across the relevant market. The marketing department gathers all the data, and makes this information available to the R&D department, which will take action in response to the findings and proceed to keep the company on top of current market needs.
Consumer demands often change very quickly, and the research and development department must be alert and adapt to these market fluctuations accordingly. Companies often allocate millions of dollars to research and development so that they can continually modify and update their products to preserve a brand's position within the market. Leading products — whether a drug, or a laundry detergent, or anything else — usually will not remain in the number one market position forever without some type of improvement and advancement.
An R&D department may also be tasked with ensuring that products are manufactured within an appropriate time frame, and that they meet specific quality and cost requirements. For example, a particular ingredient or component of a product suddenly may become too expensive or outdated, and the department will need to explore other means to replace the missing pieces. Therefore, R&D departments often maintain close ties with engineers, chemists, and other product specialists.
Research and development departments will provide advancements in products that range from simple updates of features to dramatic discoveries of new cures for diseases, depending on the field and the company's needs. The aim, in most cases, is to ensure that each product meets all regulations, legal requirements, and the highest standards in quality control. Research and development works in conjunctions with other departments to achieve these aims.

We have a patent pending product being reviewed in the R&D department of a major food company. It has been passed from the senior purchasing director to the R&D and has been three, going on four weeks in their hands. Our latest correspondence from the company is that it is still in review. Our question is how long does something like this take? And is this a positive thing on the longer it takes?
And when should we ask them again on any progress? (last time we asked was four days ago).

so why do we have the department exactly?

R&D is the main function of a company.
surfNturf- Mercedes Benz has a research and development facility in India for the last 50 years. There the engineers create improvements to the Mercedes line of cars which have recently included a shut off mechanism when a person has fallen asleep or driving in a erradic manner.
Suntan12-I have also noticed that research and development responds to the general public’s preferences and concerns with respect to food.
For example, with the heighten awareness of the dangers of Trans fats, many products now have had the Trans Fat removed from its products. Even fast food chains have removed Trans Fats from their menus.
Research and development can also change product packaging to make it more attractive and make consumers more likely to buy the product. Sometimes changing the color of a package will increase sales.
Bhutan- I have seen those panels. A lot them have to do with weight loss or diabetes drugs.
I also wanted to add that research and development is very important in the toy industry. Toys are constantly redeveloped and created to offer maximum entertainment for children.
For example, the Wii product line offers an interactive experience for kids that are multisensory.
The Wii fit model offers a series of exercise activities that measure cardiovascular fitness and balance. In fact, the Wii model will offer you a balance test in order to determine your age with respect to fitness.
This highly entertaining product was a breakthrough a few years ago because there was nothing else like it on the market. The great thing about the Wii Fit product is that it offers a great fitness experience that also improves hand eye coordination in children.
Research and development is important for a company to grow. Pharmaceutical companies research and develop drugs as the time that will improve the quality of life of people.
Often these experimental drugs might be tested in clinical trials in which the participants are terminally ill and taking these experimental drugs in order to lengthen and improve the quality of life.
Sometimes researchers conduct drug studies in which they ask for participants that may have been affected my certain medical conditions if they would like to participate in the study.
The participants are compensated and have to take the drug proposed in the study in order to measure its effectiveness.
