化学平衡(习题及答案)解析

101kPa大气平衡的水中此c(O2)。[大气中p(O2)=21.0kPa]
解：
K ceq (O2 ) / c pO2 / p
20℃时： K 1.38 103 1.38 103 1
K
ceq (O2 ) / c pO2 / p
ceq (O2 ) / c 21.0 /101
1.38103
ceq(O2)=2.87×10-4(mol·dm-3)
对于放热反应， ΔrHm⊙ <0，温度升高， K⊙减小， Q> K⊙，平衡向逆向移动。
对于吸热反应， ΔrHm⊙ >0，温度升高， K⊙增大， Q <K⊙，平衡向正向移动。
2．反应3H2(g)＋N2(g)=2NH3(g) △rHmθ>0，在密闭容器该反应达到平衡时，若降低温度，平衡向逆反应方向移动；若恒容条件下，充入惰性气体，增加系统的总压力，则平衡不移动。

香港朗文英语4A-Chapter-5复习提要

《朗文英语4A》复习提要Chapter 5: Animals big and small大大小小的动物I. 经过第5章的学习，下面的新单词我们要准确无误地读(read them correctly)，知道它们的中文意思(know the Chinese meaning)，不看书进行英汉互译(translate)，并且还要会拼写(spell)。

The panda, the hippo and the elephant are heavy.The hippo is heavier than the panda.The elephant is the heaviest.4. The rabbit, the rat and the mouse are small.The rat is smaller than the rabbit.The mouse is the smallest.总结: (1). 比较级结构：A+ be+ adj.er + than+ B. : A比B……be动词由时态和主语A决定。

Chapter5第二节省词法

Chapter 5 英汉词法翻译技巧第二节省略法（omission）省略译法——是指出于译文语法和习惯表达法的需要，把原文中需要而译文中又不需要的单词、词组等在翻译过程中加以省略的翻译方法。

原文中有些词在译文中不译出来，是因为译文中虽无其词而已有其意，或者在译文中是不言而喻的。

换言之，省略是删去一些可有可无的，或者是那些如在译文中保留下来则会使语言表达累赘啰嗦或不合汉语语言表达习惯的词语，而不是把原文的某些思想内容删去。

省略法一般用于以下两种情况：一是从语法角度进行省略；二是从修辞角度进行省略。

一、从语法角度英汉两种语言在语法上差异较大，如：英语有冠词，汉语没有；英语重形合、连接词较多，汉语重意合、连接词较少；英语介词丰富，多达280多个，汉语介词较少，只有30来个；英语中经常使用代词，尤其是经常使用人称代词、关系代词等，汉语中代词则用得较少。

因此，英译汉时可在不损害准确传达原文内容的前提下根据具体情况将冠词、连接词、介词、代词等省略，使译文练达晓畅。

省略冠词1) A teacher should have patience in his work. （表类别）2)The horse is a useful animal.3)The moon was slowly rising above the sea. （独一无二）4)He left without saying a word.5)Robert said he was getting a dollar a mile. 每开一英里就赚一块钱6)The children are of an age.省略连接词7)He looked gloomy and troubled. （并列）忧愁不安8)Despite the privation, and the mounting toll of dead and wounded, however, morale remained intact, andpeople still smile in the street. 尽管供应不足，伤亡增加，然而士气并未受到影响。

The Indo-European Language Family is one of the most important language families in theworld. It is made up of most of the languages of Europe, the Near East and India. English belongs to this family and the other members of the Indo-European have more or less influence on English vocabulary. A knowledge of the Indo-European Language Family will help us understand English words better and use them more appropriately.2.

When in the course of human events, it becomes necessary for one people to dissolve the political bonds which have connected them with another, and to assume among the powers of the earth separate and equal station to which the laws of nature and of nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.Most of the content words are either of Greek or Latin origin. What are left are mostly functional words. This shows that Greek and Latin play a very important part in the English vocabulary.8. eventful [Latin + English] hydroplane [Greek + Latin]falsehood [ Latin + English] pacifist [Latin + Greek]saxophone [German + Greek] heirloom [ French + English]joss house [ Portuguese + English] television [Greek + Latin]9. amateur (late) finacé (late) empire (early)peace (E) courage (E) garage (L)judgement (E) chair (E) chaise (L)grace (E) servant (E) routine (L)jealous (E) savaté (L) genre (L)gender (E) début (L) morale (L)state (E) chez (L) ballet (L)11. allegro, f 轻快andante, j 行板diminuendo, g 渐弱largo, d 缓慢pianoforte, a 轻转慢alto, i 女低音crescendo, b 渐强forte, e 强piano, h 轻soprano, c 女高音12. cherub (Hebrew) snorkel (G)coolie (Hindi) tulip (Turk)lasso (Sp) wok (Ch)shampoo (Indian) chocolate (Mex)tepee (Am Ind) jubilee (Gr)kibitz (G) Sabbath (Heb)chipmunk (Am Ind) tamale (Mex)cotton (Arab) voodoo (Afr)loot (Hindi) sauerbraten (G)13. a. alligator b. lococ. rodeod. bonanzae. igloof. blitzkriegg. wigwam h. canoei. hurricane j. boomerangk. ponchos【Chapter 3】1. a. morpheme b. allomorphc. bound morphemed. free morphemee. affixf. inflectional affixg. derivational affix h. rooti. stem j. base6. individualistic undesirablesindividualist [stem, base] undesirable [stem, base]individual [stem, base] desirable [stem, base]dividual [stem, base] desire [root, stem, base] dividu [root, stem, base]7.free morpheme = free rootmorpheme bound rootbound morpheme inflectional affixaffix prefixderivational affixsuffix【Chapter 4】Affixation5. non-smoker incapable impracticaldisobey insecurity irrelevantimmature inability/disability unofficiallyunwillingness illegal disagreementillogical disloyal inconvenientnon-athletic6. harden horrify modernizememorize falsify apologizedeepen glorify sterilizelengthen intensify beautifyfatten sympathizea. apologizedb. beautifyc. lengtheningd. sympathizede. fatteningf. falsifyg. memorizing h.

The word board first denoting "a table" has later acquired two very divergent senses. Each of them has given rise to another sense from which the original notion has disappeared. The process can be shown as follows:Homonymy4. 1) Make both ends meat is a parody of make both ends meet which means “have enoughmoney for one’s needs”. Here the butcher cleverly uses the pair of homonyms meat and meet to make a pun. It makes a proper answer to the lady’s question. (1) Butchers cannot make both ends meat (make whole sausages with all meat) because they cannot make both ends meet (If they made sausages with all meat, which is more costly, they would not earn enough money to survive.) (2) Don’t complain. All the butchers do the same. I am not the only one who is making sausages with bread.2) Swallow is a bird which is seen in summer. But by one swallow we see, we cannotdeduce that it is already summer time. Swallow can also mean a mouthful of wine. On a cold winter day, if one has a swallow of wine, one may feel warm.3) Arms has two meanings: weapons; the human upper limbs. Since “a cannon ball took offhis legs”, the soldier was not able to fight on, so he “laid down his arms”, which means “surrender”. It can also mean he laid down his upper limbs.Synonymy3. avaricious: greedy courteously: politelyemancipate: set free customary: usualwidth: breadth adversary: opponent gullible: deceived remainder: residueinnocent: sinless obstacle: obstruction vexation: annoyance5. a. identifiable b. safetyc. motivatesd. delicatee. surroundingsf. artificialg. prestige h. perspirei. accomplishment j. silentk. impressive l. evaporate6. run move spinturn whirl roll7. a. stead b. gee-gee c. riped. maturee. effectivef. efficientg. fatigued, children h. tired, kids i. declinedj. refused k. rancid l. addledm.

In Sentence 1), got, furniture, recently are superordinates because they are general and convey a very vague idea whereas in Sentence 2), the three words are replaced respectively by bought, cupboard, three days ago, which are subordinates, conveying a definite and clear idea. So Sentence 2) is better than Sentence 1.In Sentence 3), it is said, magnificent building, destroyed, yesterday are superordinate terms, which are comparatively much more general than the news says, Royal Hotel, burnt down, last night respectively in 4), which can be described as subordinates. Since 4) is clearer than 3) in meaning, it is better.Semantic field3. Group 1 is synonymously semantic field and Group 2 is semantic filed. The difference lies: In 1 the words are synonyms, none of them covers the meaning of another, and they differ only in style and emotive values. In 2 the words are not synonyms, but each refers to a specific type of horse. Horse is a cover term or superordinate, and others are subordinates. These terms have no difference in style or affective meaning.【Chapter 7】4. 1) extension 2) extension3) narrowing 4) degradation5) elevation 6) narrowing7) extension 8) extension9) narrowing 10) narrowing11) elevation 12) degradation13) degradation 14) degradation5. a. associated transferb. abstract to concretec. concrete to abstractd. abstract to concretee. abstract to concretef. abstract to concreteg. associated transferh. associated transferi. synesthesia (transfer of sensation from sight to hearing)j. synesthesia (transfer of sensation)6. a. objective b. subjective, objectivec. objectived. subjectivee. subjectivef. subjectiveg. subjective h. subjective, objective7. a. die b. graveyardc. bedlam疯人院d. old peoplee. strikef.
