I must admit that the ames of passion are more active, sharp and keen. But that re is a rash one, ckle, uctuating and variable; it is a feverish re, subject to attacks and relapses, which only gets hold of a corner of us. The love of friends is a general universal warmth, temp真的不掉线吗？、？erate moreover and smooth, a warmth which is constant and at rest, all gentleness and evenness, having nothing sharp nor keen. What is more, sexual love is but a mad craving for something which escapes us:Like the hunter who chases the hareThrough heat and cold,Over hill and dale, yet, Once he has bagged it, he thinks nothing of it; Only while it ees away, does he pound after it.As soon as it enters the territory of friendship (where wills work together, that is) it languishes and grows faint. To enjoy it is to lose it: its end is in the body and therefore subject to satiety. Friendship on the contrary is enjoyed in proportion to our desire: since it is a matter of themind, with our souls being puried by practising it, it can spring forth, be nourished and grow only when enjoyed. Far below such perfect friendship those ckle passions also once found a place in me not to mention in La Boe tie, who confesses to all too many in his verses. And so those two emotions came into me, each one aware of the other but never to be pared, the rst maintaining its course in a proud and lofty ight, scornfully watching the other racing along way down below.As for marriage, apart from being a bargain where only the entrance is free (its duration being fettered and constrained, depending on things outside our will), it is a bargain struck for other purposes; within it you soon have to unsnarl hundreds of extraneous tangled ends, which are enough to break the thread of a living passion and to trouble its course, whereas in friendship there is no trac or merce but with itself. In addition, women are in truth not normally capable of responding to such familiarity and mutual condence as sustain that holy bond of friendship, nor do their souls seem rm enough to withstand the clasp of a knot so lasting and so tightly drawn. And indeed if it were not for that, if it were possible to fashion such a relationship, willing and free, in which not only the souls had this full enjoyment but in which the bodies too shared in the union where the whole human being was involved it is certain that the loving-friendship would be more full and more abundant. But there is no example yet of woman attaining to it and by the mon agreement of the Ancient schools of philosophy she is excluded from it.真的不掉线吗？、？完形填空专练完形填空讲解 完形填空题是英语考试中的必考题，它既是考查同学们的英语知识又是检测同学们的分析判断的能力和综合运用所学知识的能力。是一种高要求的试题。 一般来说，完形填空是将一篇难度适中的短文，将其中某些词挖空，让同学们在所给的ABCD四项选项中选出最佳答案，使其通顺，挖空的密度越大，试题越难，反之亦然。一般文中有10至20个单词或短语被抽去，做题时可按以下几个步骤进行。 1. 通读全文，掌握大意。 做完形填空题，阅读理解是关键，要快速读完全文，也可进行“跳读”或“掠读”。虽然文章中有些空格，但仍可以了解文章的主要内容。在阅读时，短文的第一句往往很重要，提供时间、地点、人物、事件，因此我们可以凭借此句推断文章的内容。此外，短文各段的第一句也很重要。把握这些关键词，往往能理清文章的脉络。 2. 然后读一遍选项，知道均有哪些备选项。 3. 再读全文，并且可以边读边用铅笔将所选的选项的内容填在空白处。 这是一个关键性的分析判断阶段。就是要根据文章提供的线索选择各空白处的最佳答案。在此同时要根据上下文的联系，瞻前顾后，掌握文章脉络，还要掌握文中暗含因素，同时还要掌握一些常识，选择最佳答案。对每题所给词语的确切含义进行分析比较，考虑到全文意境的影响，还要进行逻辑思维、推理的方式来进行答题。做题时，不要孤立地局限于某个单句所提供的语境，以免断章取义，顾此失彼或无所适从。文中人物的观点，态度、语气、感情等对于选项的确定也起着重要的作用。在无法确定最佳选项时，可采用排除法，逐一排除干扰选项。首先剔除内容上、逻辑上明显矛盾的选项，然后再仔细鉴别词、句的含义，选出最佳答案。 4. 再串读，用铅笔填上，然后看看文章意思是否通顺，语法语义是否准确，是否可恢复原貌。 此时对全文意思的理解程度会更为清楚，这样就为在解决那些少数疑难问题时排除了在逻辑意义上易选错的选项。先看看哪些选项与文章不符，然后综合运用词汇、句型、语法等知识反复地字斟句酌，来确定最后的答案。这时就要凭借语感和语言综合运用能力做出判断，真的不掉线吗？、？纠正错误，提高答案的正确率。不能孤立地检查每个要求填的空白处，应遵循由整体到部分，再由部分到整体的理解文章的规律，认真检查所选的词是否得当，语法是否正确。如果此时你对某一选项产生了怀疑，改动时要格外慎重，否则，可能把正确的答案改错。 5. 最后还要利用自己各方面的知识和语言知识、历史知识、生活常识等，细微分析比较，理解中心，全面验证。 例题 Carol and Susan are very good friends They are in the same _1_ at school and they often visit _2_ home at weekends (周末). Now they are _3_ eight years old. Carols mother has got a new baby. Carol is very _4_ to have a little sister. So she is always talking about her to Susan. At first she is very _5_ in the new baby because she doesnt have any brothers or sisters. But _6_ some time she begins to get tired of Carols endless talking (喋喋不休地谈论) about it. She also feels a little jealous (嫉妒) of her friend. One morning when the two girls _7_ in the school ground, Carol says to Susan, Do you _8_, Sue, my baby sister has put on nearly half a pound in weight (体重增加了半磅) this week. That is not very _9_. answers Susan. I know a baby and he puts on ten pounds a day. Oh, that cant be _10_. answers Carol laughingly. Whose baby is it? An elephants says Susan. 1. A. grade B. table C. class D. group 2. A. each others B. their C. theirs D. each other 3. A. all B. two C. both D. either 4. A. angry B. sorry C. surprised D. glad 5. A. interesting B. interested C. happy D. satisfied 真的不掉线吗？、？6. A. before B. for C. after D. at 7. A. play B. meet C. weight D. walk 8. A. hear B. think C. find D. know 9. A. much B. many C. few D. little 10. A. impossible B. wrong C. true D. sure 解题指导1、选C。从Carol和Susan每天在一起可推测她们同班。故C项class是正确选择。不同班的学生，即使在同年级也接触较少，故不选A。 2选A。本句意为她们经常互相到对方家里去玩，由此可知，home前应该是一个修饰语，B项人称错误，CD两项是名词性的，只有A项名词所有格可起形容词作用，修饰名词home。 3选C。这里是指两个人都八岁，both是代词，指两个人，all指三者 或三者以上，either指单数，two是数词，只有C项both正确。 4选D。从下面Carol经常对Susan谈起她的小妹妹来看，Carol得了小妹妹是很高兴的。因此可推断glad是正确答案。 5选B。在所给的四个选项中，与介词in连用的只有B项interested，其余三项无此用法，意思也不与上下文连贯，故应排除。 6选C。这里是指过了一段时间，Susan对此事厌倦了，应该用after来表示，before是反义词，for也表示一段时间，但那是指谓语动词持续的时间，本句谓语是终止性动词，故不妥。 7选B。本题是指两个女孩在操场上遇见，若用play或walk，应该用进行时态才对，C项明显不合题意。 8选D。这里是Carol告诉Susan，所以说Do you know即“你知道吗？”这里用不着Susan思考或发现，故应排除BC两项，容易混淆的是hear后接宾语从句时作“听说”解，“听说”的是别人的事，自己家的事一般不会问别人是否听说，故A项也不正确。 9选A。本句是对上句的回答，应选A项much意即“那不算多”，CD两项意思相反，B项many要修饰可数名词，均应排除。 10选C。这时对Susan所说话真实性的否定，由于本句是否定句，故选C项true ，A B两项意思相反，D项sure的主语应该是人，均不合题意。 真的不掉线吗？、？ 完形填空练习 完形1 Ma Lili is a Chinese _1_.
