How often do you exercise词汇讲解与练习

How often do you exercise?词汇讲解与练习

1．exercise的用法

（1）作动词，意为“锻炼、运动”。

例如：--- 你多久锻炼一次？

--- I. 我每天都锻炼。

（2）作不可数名词，意为“锻炼、运动”。

例如：运动使我保持健康。

（3）作可数名词，意为“运动、操”，“练习题”。

例如：我们每天做早操。

我们做英语练习以便学好英语

2.sometimes，sometime，some time some times，几个形似的词的区别。

(1) sometime是副词，意为"在某个时候"，"某时"后面还加上一个大时间

eg：Will you come again sometime next week?

她明年的某个时候来这儿。.

(2) some time是名词固定词组，意为"一段时间"，做时间状语用

eg：我将在这儿还要呆一段时间。

He worked on the trouble for some time.

(3) some times是名词词组，意为"几次，几倍"。

eg：上个月我遇见他几次。.

The factory is some times larger than that one.

3.most表示“大部分，多半”的意思。

例如：大部分孩子喜欢电脑游戏。

most与most of 的区别

(1) most后可直接跟名词(可数或不可数)，同时，也可接有形容词修饰的名词。

例如：Most boys like playing football. 大部分男孩都喜欢踢足球。

I always spend most time learning English. 大部分时间我总是花在学习英语上。

(2)most后不能直接跟有定冠词、指示代词或物主代词所修饰的名词，遇到这些情况用most of 代替most。

例如：去年我把大部分时间都花在学弹钢琴上了。

I did most of that difficult work. 那件困难的工作绝大部分都是由我做的。

另外，还需要注意以下几点：

(3)most of 后跟人称代词时，应用复数形式的人称代词宾格。

例如：Most of them are going off to Guangzhou next week.

他们中的多数人都准备下星期去广州。

(4)most 前有定冠词时，可用来修饰多音节形容词，表示最高级，意为“最”。

例如：This is the most beautiful flower. 这是最漂亮的花。

但是，如果most前有不定冠词a，则表示“非常；很”，相当于very。例如：She is a most beautiful girl.

5. But my mother wants me to drink it. 我妈妈想让我喝它．

1）本句中me作动词want的宾语，to drink 应用来补充说明me，即want sb. to do sth. 想让某人做某事。例如：我想让他帮助我。

2）want还经常直接跟物作宾语，表示“想要某物”或直接跟不定式，表示“想要做某事”。

例如：我想要一件新衣服。

我想吃个苹果。

3）除want常用不定式做宾补外，其他常用于此结构的动词还用：tell, ask, invite, get等。

其肯定形式为：tell / ask / invite / get sb. to do sth.告诉/请求/邀请/让某人做某事。

例如：We invited him to attend our meeting yesterday.

昨天我们邀请了他出席我们的会议。

其否定形式需在to do sth. 前加not 构成：

tell / ask / get sb. not to do sth. 告诉/请/让某人不要做某事例如：I have told him not to play CDs so loud.我已经告诉他不要把CD的声音放的那么大。

此外：在感官动词hear, see, watch, feel, notice等和使役动词let、make、have等词后,动词不定式作宾补，要省略to。

例如：We felt the house shake. 我们感到房子在摇动。

Let him do it. 让他做吧。

6. She says it is good for my health. 她说这对我的健康有益．

1）be good for意为“对……有好处”；其反义词为“be bad for”，

意为“对……有害”．

例如：喝牛奶对你的健康有好处。

吃太多的糖对牙齿有害。

2）health为名词，意为“健康”，其形容形式为healthy，意为“健康的”。

在名词词尾加y构成形容词，类似的词还有：

rain—rainy 雨—下雨的sun—sunny 太阳—晴朗的

luck—lucky 幸运—幸运的wind—windy 风—刮风的

随时练习：My ____ lifestyle and good food _____me to study better . A. healthy，help B. healthy，helps C. health，help D. health，helps

由be good构成的其他词组

(1) be good at... 表示“擅长某一学科知识或某种技能”或“在某方面做的好”，后接名词、代词

或v-ing形式。

例如：Mary is good at Chinese.玛丽语文学得很好。

The twins are good at swimming.这对双胞胎擅长游泳。

(2) be good to... 表示“对……友好”，其中good可用friendly代替。

例如：天下父母都对自己的子女很好。

【2011中考题】

1. Reading in the sun is bad _____ your eyes

我尽量多吃蔬菜．

--- Will you come with us? 要不要和我们一起去？

--- Maybe. 可能吧。

may be是情态动词加动词原形的形式，译成“可能是，也许是”，使用时注意与maybe区分。

例如：He may be twenty. = Maybe he is twenty. 他可能是二十岁。

10. although表示“虽然……但是……”，英语与汉语不同，表示“虽然……但是……”时，

although与but只用其中的一个，不能同时出现在句中，

例如：Although it was dark, he still went on working.

= It was dark, but he still went on working.

虽然天黑了，可是他们还是继续工作。

注意：

与although类似，引导让步状语从句的词还有：though，even though，although，though和even though 这几个词意思都差不多，都是“虽然”，“即使”的意思，可以互换。其中although较为正式，even though略带强调。

11. time表示不可数名词，意为"时间"。表示可数名词，意为"次数，倍数"。

eg：What time is it?

Time and tide never wait for men.

I go to the movies three times a week.

The size of the new museum is four times larger than the old one 写作进行时

砌体结构复习题及参考答案

一．填空题 1、结构的 安全性 、 适用性 、 耐久性 统称为结构的可靠性。 2、多层砌体房屋的高度不超过40m ，质量和刚度沿高度分布比较均匀，水平振动时以 剪切 变形为主，因此采用 底部剪力法 简化分析方法。 4、砌体是由_块材 和 砂浆 组成的。 5、砌体受拉、受弯破坏可能发生三种破坏：沿齿缝（灰缝）的破坏，沿砖石和竖向灰缝的破坏，沿通缝（水平灰缝）的破坏。 6、一般情况下，砌体强度随块体和砂浆强度的提高而提高； 7、砂浆强度越低，变形越大，砖受到的拉应力和剪应力越大，砌体强度越低；流动性越大，灰缝越密实，可降低砖的弯剪应力； 8、灰缝平整、均匀、等厚可以 降低 弯剪应力；方便施工的条件下，砌块越大好； 9、普通粘土砖全国统一规格：240x115x53，具有这种尺寸的砖称为标准砖； 10、砌体抗拉、弯曲抗拉及抗剪强度主要取决于 灰缝 的强度； 11、粘接力分为 法向粘结力 和 切向粘结力 两种； 12、在实际工程中，按0.4m f σ=时的变形模量为砌体的弹性模量。 13、结构的功能要求：安全性 、 适用性 、 耐久性。 14、在截面尺寸和材料强度等级一定的条件下，在施工质量得到保证的前提下，影响无筋砌体受压承载力的主要因素是构件的高厚比和相对偏心距。《砌体规范》用承载力影响系数考虑以上两种因素的影响。 15、在设计无筋砌体偏心受压构件时，偏心距过 大 ，容易在截面受拉边产生水平裂缝，致使受力截面 减小 ，构件刚度 降低 ，纵向弯曲影响 变大 ，构件的承载力明显 降低 ，结构既不安全又不经济，所以《砌体规范》限制偏心距不应超过 0.6y 。为了减小轴向力的偏心距，可采用 设置中心垫块 或 设置缺口垫块 等构造措施。 16、局部受压分为 局部均匀受压 和 局部非均匀受压 两种情况。局部受压可能发生三种破坏：竖向裂缝发展引起的破坏、劈裂破坏和直接与垫板接触的砌体的局压破坏。其中直接与垫板接触的砌体的局压破坏仅在砌体材料强度过低时发生，一般通过限制材料的最低强度等级，可避免发生这种破坏。 17、砌体在局部受压时，未直接受压砌体对直接受压砌体的约束作用以及力的扩

词汇学 名词解释(部分)

Types of meaning Types of lexical changes 1.Elevation:词义升格 Definition: words rise from humble beginnings to positions of importance Some words early in their history signify something quite low or humble, but change as time goes by to designate something agreeable or pleasant. For example: nice: ignorant---foolish---delightful, pleasant Marshal: a keeper of horses---a high ranking army officer So elevation refers that the meaning of word changes from the neutral/negative to positive. 2.Old English:It refers to the English starting from 450 to 1100 AD. The old English is made up of different sources of languages spoken then –that of Anglo-Saxons, that of Celts, and that of Jutes, with a lot of Latin elements used for common peopl e’s life. 3.Bound morpheme: It is the smallest unit of grammar, a unit which cannot occur as separate words. They have no independent semantic meaning; instead, they have: Attached meaning E.g. un-kind, hope-ful Grammatical meaning E.g. cat-s, slow-ly, walk-ing, call-ed For an exact example, in the word “careful”, care is free morpheme, “-ful” is a bound morpheme. 4.Hyponymy: Hyponymy deals with the relationship of semantic inclusion, or to say, the relationship between general lexical items and specific lexical items. That is to say, when X is a kind of Y, the lower term X is the“hyponym”, and the upper term Y is the “superordinate”. For example, “fiction”is the superordinate of “novel”, “novelette”and “short story”, which are the hyponyms of “fiction”. Knowing the semantic features of the hyponyms and their superordinates can help us achieve vividness, exactness, and concreteness in expression.

词汇学概念整理

1、区别Lexeme Word Morphemes A lexeme is the smallest unit in the meaning system of a language. The lexeme “give” includes as members “give”, “gives”, “given”, “giving”, “gave”, but excludes “giver” and “givers”. A lexeme is an abstract unit. It can occur in many different forms in actual spoken and written sentences. A word is a minimal meaningful unit of a language that can function independently. Morphemes are known as minimal meaningful units of a language. 2、组合形式 A combining form is a bound root that can form a new word by combining with another combining form, a word, or sometimes an affix, for example techno- and -phobe in technophobe. 3、区别Root base sterm ?A root is the basic form of a word which cannot the further analyzed without total loss of identity. e.g. international ?A base is a form to which affixes of any kind (both derivational and inflectional) can be added. e.g. grace ---- graceful ---- ungraceful ?The stem is used only when we deal with inflectional affixes, so any form to which an inflectional affix is attached is a stem. e.g. works, workers, workshops 4、转化法定义 Conversion is the formation of new words by converting words of one class to another class. Since words that are made do not change in morphological structure but in function, this process is also known as functional shift. Words produced by conversion are primarily nouns, adjectives, and verbs. N---V bottle to bottle Adj----V dry to dry V------N look have a look 5、截短法定义及分类 Clipping/shortening(截短法)is the formation of new words by cutting a part off the original and using what remains instead. Words formed in this way are called “clipped words”. There are four common types of clipping: apocope/back clipping, aphaeresis/front clipping, front and back clipping, syncope.例子exam---examination phone---telephone tec----detective pacifist----pacificist 6、关联意义的定义与分类 Associative meaning is the secondary meaning supplemented to the conceptual meaning. It differs from the conceptual meaning in that it is open-ended and indeterminate. 1.Connotative meaning refers to the overtones(弦外之音) or associations suggested by the conceptual meaning.woman--frail,cowardly,emotional 2.Affective meaning expresses the speaker’s attitude towards the person or thing in question.dear hello 3.Collocative meaning is that part of the word meaning suggested by the words with which it co-occurs. pretty handsome 4.Stylistic meaning: daddy male parent 7、同形异义词的定义及分类 ?Concretely speaking, homonyms are words different in meaning, but either identical both in sound and spelling or identical only in sound or spelling. ?Homonyms fall into three types: absolute homonyms, which are words identical both in sound and spelling; date base . homophones, which are words identical only in sound but different in spelling and meaning; night/knight leak/leek homographs, which are words identical only in spelling but different in sound and meaning.tear sow 8、区分歧义与含混 Ambiguity refers to the phenomenon that a word, phrase or sentence has more than one meaning. Are you engaged?Vagueness is caused by the indistinction and unclearness of language. A vague word is one that has an indefinite denotation(外延概念).forest wood city town 9、同义词及其分类 A synonym is a word or expression that has the same or nearly the same meaning as another in the same language. Synonyms can be classified into two groups: perfect synonyms, which are words identical in grammatical meaning and lexical meaning including conceeptual and associative meaning, compounding/composition and partial synonyms, which are similar in essential meaning, but embrace different shades of meaning or different degrees of a give quality.couple/pair 10、上义词和下义词 The relationship in which the meaning of a more specific word is included in that of another more general word is called hyponymy. For example, the words animal and dog are related in this way. The specific term dog is called a hyponym, and the general term animal is called a superordinate term. 11、词义变化 Extension of meaning, also known as generalization, is a process by which a word which originally had a specialized meaning has now become generalized or has extended to cover a broader and often less definite concept. Narrowing of meaning, also called specialization, is a process by which a word of wide meaning acquires a narrower or specialized sense. Elevation or amelioration refers to the process by which words rise from humble beginnings to positions of importance. Degadation or pejoration of meaning is a process by which words of good origin or affective neutrality fall into ill reputation or come to be used in a derogatory sense. 12、为什么英语谚语具有结构固定性 Characteristics of idioms: 1) Semantic unity : Each idiom is a semantic unity. The meaning of an idiom is very often not the total sum of the meanings of the constituent parts. In other words, an idiom
