1、课时一other,another,others,the others,the other的用法和区别1.other可作形容词或代词，做形容词时，意思是“别的，其他”，泛指“其他的（人或物）”。如： Do you have any other question(s)? 你还有其他问题吗？ Ask some other people. 问问别人吧！ Put it in your other hand. 把它放在你另一只手里。 2.the other指两个人或物中的一个时，只能用the other，不能用another，此时的other作代词。如： He has two daughters. One

2、 is a nurse, the other is a worker. 他有两个女儿，一个是护士，另一个是工人。 the other后可加单数名词，也可加复数名词，此时的other作形容词。如： On the other side of the street，there is a tall tree. 在街道的另一边，有一棵大树。 Mary is much taller than the other girls. 玛丽比其他的女孩高得多。 He lives on the other side of the river. 他住在河的对岸。 3.others是other的复数形式，泛指“另外几个”

3、，“其余的”。在句中可作主语、宾语。如： Some of us like singing and dancing, others go in for sports. 我们一些人喜欢唱歌和跳舞，其余的从事体育活动。 Give me some others, please. 请给我别的东西吧！ There are no others. 没有别的了。 4.the others意思是“其他东西，其余的人”。特指某一范围内的“其他的（人或物）”。是the other的复数形式。如： Two boys will go to the zoo, and the others will stay at home

4、. 两个男孩将去动物园，其余的留在家里。 the others=the other +复数名词，这在第2条中已经有所介绍。 5.another=an+ other，既可作形容词，也可作代词，只能用于三个或更多的人或物，泛指同类事物中的三者或三者以上的“另一个”，只能代替或修饰单数可数名词。如： I dont like this one. Please show me another. 我不喜欢这一个，请给我看看另一个。 I have three daughters. One is a nurse, another is a teacher and another is a worker. 我有

5、三个女儿。一个是护士，另一个是教师，还有一个是工人。 else表示“另外的”表示“除此之外 ，还有”，相当于besides,如： What else can I say? 我还能说什么呢？1Shehastwosons,_isateacher,_isanengineer Aone,theotherBone,anotherCanother,anotherDone,other 2Youhaveseenoneofthephotosofmysisters,nowIllshowyou_ AanotherBotherCothersDtheothers 3_wenttothegreatwall,_visite

AanotherBotherCothersDtheother课时八频度副词 1.定义usually/ sometimes/always/often等词在英文中被称为“频度副词”，是用来表示动作频率的，但程度上有别。常见频度副词按频率大小排列如下： always（100%）usually（80%）often（60%）sometimes（40%）sel

9、dom（20%） never（0%） 2.频度副词的位置频度副词在句中习惯上位于be动词、助动词等之后，行为动词之前。 1. 在be动词之后。如： She is sometimes very busy. 她有时很忙。 2. 在第一个助动词或情态动词之后。如： I will never forget this lesson. 我将永远忘不了这一课。 3. 在实义动词之前。如： We often go there. 我们常去那儿。 sometimes也可放在句首、句中或句末，often也可放在句末（一般不放在句首）。如： Sometimes she writes to me. =She write

10、s to me sometimes. 她有时候给我写信。 She writes to me often. 她经常给我写信。 如果有两个助动词，频度副词通常放在第一个助动词后面。如： We have never been invited to one of their parties. 他们聚会，一次也没邀请过我们。 She must sometimes have wanted to run away. 她有时候一定想到过要逃走。3.频度副词的用法always 频率最高，表示动作重复、状态继续，表示“一直、总是”，其反义词为never。always等与not连用时，表示部分否定。如： The r

11、ich are not always happy. 有钱的人并不总是快乐的。 如果要变为否定句，应将always改为never才能全部否定。如： Li Ping is always late for school. 上学总是迟到。 Li Ping is never late for school. 李平上学从不迟到。（全部否定） Li Ping is not always late for school. 李平上学不总是迟到。（部分否定） 频度副词通常和一般现在时连用，表示动作发生的频率。但always与进行时连用时，并不强调动作正在进行，而是表示赞叹、厌烦等情绪。如： He is alway

12、s thinking of others. 他总是想着别人。（赞叹） She is always asking silly questions. 她总是问些愚蠢的问题。（厌烦） The boy is always asking for money. 这个小男孩总是要钱。（厌烦） usually意为“通常”，表示习惯性动作或状态，很少有例外。如： We usually go to school at seven in the morning. 我们通常在早上七点上学。 My mother and I usually go shopping on Sundays. 我和妈妈通常在星期天去买东西。

13、Often意为“经常，时常”，表示反复性的动作或状态，中间有间断，不如usually那么频繁。其反义词是seldom。often在句尾时常被very或quite修饰。如： It often rains here in April. 这儿四月份常下雨。 he boys often eat noodles and the girls sometimes eat them. 男生经常吃面条，女生有时吃。 I often chat with my friends under the big tree. 我经常在这棵大树下和朋友聊天。 He writes to his friends quite oft

14、en. 他常给他的朋友写信。 sometimes意为“有时”，频率不及often，表示动作偶尔发生，间断时间较长。其位置比较灵活，放在句首、句中、句末都可。如： Sometimes we go to the cinema and at other times we go for a walk. 有时我们去看电影，有时我们去散步。 I sometimes watch TV in the evening. 我有时晚上看电视。 My father has lunch in the factory sometimes. 我父亲有时在工厂吃午饭。 seldom意为“很少”；never意为“从不”。这两个

15、副词表示否定意义，动作几乎不会发生。如： He seldom eats breakfast. 他很少吃早餐。 The little girl seldom goes out. 这个小女孩很少外出。 I will never forget your kindness. 我永远忘不了你的好意。 The boys never eat chocolate and the girls seldom eat it. 男生从不吃巧克力，女生很少吃。 Btter late than never. 谚语 迟到（迟做）总比不来（不做）好。 hardly具有否定意义，表示“几乎不、简直不”，除非特殊情况，否则不会发

16、生。如： The boy is so young that he could hardly understand it. 这个孩子太小了，不可能懂得这件事。 对上述频度副词提问时，用how often。如： I write to my brother sometimes. How often do you write to your brother？ 4.频度副词位于助动词之前两种情况1.）为了表示强调，频度副词有时也可位于动词be、助动词、情态动词之前，此时助动词等应重读。如： She always was late. 她老是迟到。 I never can remember. 我永远也记不住

17、。 2.） 在简略答语中，当频度副词与动词be、助动词或情态动词位于句末时，频度副词必须前置。 “Philip is late again.” “Yes, he always is.” “又迟到了。”“是的，他总是迟到。” “Can you park your car near the shops?” “Yes. I usually can.” “你可以在商店附近停车吗?”“是的，通常可以。” 5.频度副词在否定句中的用法在否定句中，有的频度副词位于否定词之前或之后均可，而有的频度副词则必须位于否定词之后，而还有的频度副词却必须要位于否定词。大致情况如下： 1.） 频度副词usually和of

18、ten可位于否定词not之前或之后。 他们不常开这样的晚会。 正：They dont often hold such parties. 正：They often dont hold such parties. 星期日我们一般不在9点以前起床。 正：We dont usually get up before nine on Sundays. 正：We usually dont get up before nine on Sundays. 在否定句中，频度副词用于句中或句首，有时但会导致意思不同。 He doesnt usually sleep for two days at a time. 他很

19、少一连睡两天。 Usually he doesnt sleep for two days at a time. 他连续两天不睡觉是常事。 2.） 频度副词always总是位于否定词之后，不可位于否定句之前。 Things are not always what they seem to be. 外表往往是靠不住的。 Silence must not always be read as consent. 沉默并不见得一定意味着同意。 3.） 频度副词sometimes总是位于否定词之前，不可位于否定词之后。 Jim is sometimes not very punctual. 有时不太准时。

20、Debbie is sometimes not responsible for what she does. 有时对她所做的事不负责任。 6.频度副词位于句末的用法1）sometimes常可用于句末。 如： We all get into trouble sometimes. 我们有时都会遇到麻烦。 You cant work all the time，it does you good to go out and enjoy yourself sometimes. 你不能总是工作，有时出去放松一下会对你有好处。 2） often有时可置于句末，但通常会带有very, quite, fairly

21、, more, so等修饰语。如： Weve been there quite often. 经常去那里。 When I was young, I used to play tennis very often. 我年轻时经常打网球。 Diana used to travel a lot. These days she doesnt go away so often. 娜过去经常旅游。最近她不常出门了。 Were not exactly on intimate terms, but we see each other fairly often. 虽算不上关系密切，但还常见面。 注：有时也可不带修

22、饰语，但主要见于否定句或疑问句。 如： He writes to me often. 他经常给我写信。 Do you come here often? 你常来这儿吗? I dont come here often. 我不常来这儿。 3. usually有时也用于句末，其前不用修饰语。 Im not late, usually. 我通常不迟到。 I get paid on Fridays usually. 我通常在星期五领工资。 4.seldom 一般不用于句末，除非其前带有only，very等修饰。 We go out very seldom. 我们绝少外出。 I play basketbal

23、l very seldom indeed. 我很少打篮球。 5. always一般不用于句末，偶尔用于句末，此时它不表法“总是”，而表示“永远”。 Ill love you always. 我将永远爱你。 另外，有时用于句末是因为句子有所省略的缘故。 Generally they walked together on Sunday, but not always. 他们一般在星期日一起散步，但并不总是如此。 句中的but not always=but they didnt always walk together on Sunday。 7.频度副词位于句首的用法1） sometimes常可用于

24、句首。 Sometimes she comes late. 有时她来得晚。 Sometimes she didnt agree with me. 有时她和我意见不一致。 Sometimes we get a lot of rain in August. 有时在8月份雨水很大。 2.）often用于句首时，通常表示强调，且其前一般有quite, very修饰。 Very often he comes in late. 他常常迟到。 Quite often the phone rings when Im in the bath. 电话经常在我洗澡时响。 3）usually有时也用于句首，其前不用修

25、饰语。 Usually I get up early. 我平时起得早。 Sometimes he comes by bus, but usually he comes by taxi. 有时他坐公共汽车来，不过他通常还是打的来。 Usually cooking pots have two small handles but pans have one long handle. 通常地深底煮锅有两只把手而平底锅只有一个长长的把手。 4）always一般不用于句首，除非是用在祈使句中。 Always remember this. 请时刻记住这一点。 Always look in the mirro

26、r before starting to drive. 一定要先看看反光镜再开车。 另外，never也可用于祈使句的句首。 Never tell him the news. 千万不要告诉他这消息。 Never ask her about her marriage. 决不要问她结婚的事。 5）在正式文体中，表示否定意义的副词seldom, never可位于句首，但此时其后要用语序。 Seldom has there been such a happy meeting. 过去很少有过这样愉快的会议。 Never did he think the book would be finished so

27、soon. 他可没想到这本书会这么快看完 8.另外，once a year (每年一次), twice a week (每周两次), three times a day (一天三次), every Saturday afternoon（每星期六下午）等，这些时间状语也表示频率，它们可以和频度副词用在同一个句子中，表达上没有重复。如： We usually go to the cinema four times a month. 我们通常一个月看四次电影。 课后练习单项选择（ ）1.How often does your sister surf the Internet?

37、 this is a new one. 我的旧相机丢了，这是一架新的。Did you get a ticket?Yes， I managed to get one. 你搞到票了吗?是的，我设法搞到了一张。注：若 one 前没有形容词的修饰，则其前不能有不定冠词。比较：Im looking for a flat.

38、garden.）没有形容词修饰的 one 前不能用不定冠词，但可用 another。如：This pen doesnt work. I must buy another one. 这支钢笔坏了，我要另买一支了。另外，注意它与表特指的 it 的区别。如：Can you lend me a pen?Sorry. I havent got one. 你能借给我一支钢笔吗?对不起，我没有钢笔。Can I borrow your pen?Sorry， Im using it.我能借用你的钢笔吗?对不起，我自己正在用。二、替代表特指的单数名词，可用 it， that， the one。三者的区别是：1.

39、替代单数可数名词时，三者均可用；替代不可数名词时，不能用 the one，而要用 it 或 that。此时 it 与 that 的区别是：表示同一事物时，用it；表示同类事物时，用 that 或 the one。如：The weather here is too cold. I dont like it. 这儿的天气太冷了，我不喜欢这儿的天气。（it 在此指前面提到的 the weather）The weather of Beijing is colder than that of Guangzhou. 北京的天气比广州冷。（that 在此指代的天气与前面提到的天气为同类）My uncle b

40、ought me a dictionary and I like it very much. 我叔叔给我买了一本词典，我非常喜欢它。（it 在此就是指前面提到的叔叔给我买的词典）Your dictionary is more useful than the one my uncle gave me. 你这本词典比我叔叔给我的那本词典更有用。（the one 在此表示与前面提到的词典为同类）2. 替代事物时，三者均可用；替代人时，只能用 the one。如：Who is her husband?The one by the window. 哪位是她的丈夫？窗户边的那一位。注：当要替代性别不明的婴

41、儿时可用 it。3. 当有前置定语修饰时，只能用 the one。如：Which do you want?The red one. 你想要哪个?那个红的。She would rather have the small one than the large one. 她宁愿要小的，不要大的。4. 当有后置定语修饰时，通常用 the one。如：My room is better than the one next door. 我的房间比隔壁房间好。He said he would have the one near him. 他说要靠近他的那一个。Is that the one that was

42、 published recently? 是最近出版的那一种吗?Here are six rings. Pick out the one you like best. 这里有六枚戒指，选出你最喜欢的一枚。但是，若后置定语为 of 引起的介词短语，则通常用 that。如：The population of China is much larger than that of Japan. 中国人口比日本人口多得多。A grandparents job is easier than that of a parent. 祖父母的任务比父母的任务要轻松一些。三、替代表泛指的复数名词，通常用 ones。如

43、：Hard beds are healthier than soft ones. 硬板床比软床有利于健康。Green apples often taste better than red ones. 青苹果往往比红苹果好吃。We can lend you plastic chairs or metal ones. 我们可以借给你塑料椅子或者金属椅子。These chairs have the great advantage of being much cheaper than conventional ones. 这些椅子具有比普通椅子便宜得多的优势。四、替代表特指的复数名词，通常用 the ones。如：Id like to try on those shoes. The ones at the front of the window. 我想试试那双鞋子。橱窗里前边的那一双。Are they the ones who moved here recently? 是最近搬到这儿来的那些人吗?Dont buy the expensive apples; get the cheaper ones. 别买那价钱贵的苹果，买那便宜的。注：在口语中，也可用 those 来替代表特指的复数名词，尤其是当其后有 of 引导的介词短语或 who 引导的定语从句修饰时。如：Waves
