我大概看明白你的意思了,大家讨论一下吧.
首先,不可或缺可以翻译成：不可以有一点点的缺失
“不可”是状语+动词,“或缺”是定语+名词,去掉状语和定语,其实这个短语的结构是动词+名词,显然可以看出这是一个动词性短语,当然可以做谓语
再进一步,动词+名词我可以理解成是动宾短语,动宾短语作形容词的也有很多,比如：耀眼,刺耳
最后我的理解是：不可或缺是动宾短语做形容词,可以做谓语.

El viaje es una parte imprescindible de la vida,me gusta viajar solo con equipaje simple,camino sin la carga del destino.No importan las condiciones del arrendamiento,tampoco tengo la preocupación sobre la discrepancia con un compañero.Tiro fotos en el viaje,hago lo que quiero,también puedo practicar la habilidad de resolver los problemas,no hace falta que nadie me ayude.Pienso que a la vez se desarrollan lo fisíco y lo psicológico en mi.
Por lo tanto,me gusta viajar solo.

不可或缺
基本释义 非常重要,无法替代或缺少的.
或：稍微.编辑本段近反义词
近义词：至关重要,必不可少
反义词：多此一举( 注释:举：行动.指多余的,没有必要的举动.

B

须臾：刹那者为一念,二十念为一瞬,二十瞬为一弹指,二十弹指为一罗预,二十罗预为一须臾.须臾指很短的时间、片刻.
不可或缺：或,稍微；不可以缺少.
须臾不可或缺：片刻都不能缺少,片刻都离不开.
至于由来,并不是古语演化来的, 不可或缺前面一般为名词,须臾作为状语只能是强调、修饰的作用,如A对B而言不可或缺------A对B而言须臾不可或缺.须臾不可或缺是由两个无关联的词语随意组合而来,没有什么深刻含义或内涵.

The love of beauty is an essential part of all healthy human nature. It is a moral quality. The absence of it is not an assured ground of condemnation, but the presence of it is an invariable sign of goodness of heart. In proportion to the degree in which it is felt will probably be the degree in which nobleness and beauty of character will be attained. Natural beauty is an all-pervading presence. The universe is its temple. It unfolds into the numberless flowers of spring. It waves in the branches of trees and the green blades of grass. It haunts the depths of the earth and the sea. It gleams from the hues of the shell and the precious stone. And not only these minute objects but the oceans, the mountains, the clouds, the stars, the rising and the setting sun---all overflow with beauty. This beauty is so precious, and so congenial to our tenderest and noblest feelings, that it is painful to think of the multitude of people living in the midst of it and yet remaining almost blind to it. All persons should seek to become acquainted with the beauty in nature. There is not a worm we tread upon, nor a leaf that dances merrily as it falls before the autumn winds, but calls for our study and admiration. The power to appreciated beauty not merely increases our sources of happiness---it enlarges our moral nature, too. Beauty calms our restlessness and dispels our cares. Go into the fields or the woods, spend a summer day by the sea or the mountains, and all your little perplexities and anxieties will vanish. Listen to sweet music, and your foolish fears and petty jealousies will pass away. The beauty of the world helps us to seek and find the beauty of goodness.

应该是这样的.

解题思路：（1）明矾、硫酸铝、硫酸铁等可水解生成具有吸附性的胶体；
（2）净水是除去水中的悬浮物，水的软化是除去水的钙离子和镁离子；
（3）根据离子的定向移动判断；
通电时，阳极发生氧化反应生成氯气；
（4）先生成氢氧化镁，氢氧化镁和盐酸反应生成氯化镁，易除去氯化钠等杂质；
（5）增大压强，可使平衡向正向移动，分离出生成物，可使平衡向正向移动，提高转化率．

（5）混凝剂是吸附水中的微小悬浮颗粒，凝聚成较大的颗粒，而快速沉降的主要作用，要具备水解生成胶体的性质，所以常有铝盐或铁盐在水中发生水解生成相应氢氧化物胶体，
故答案为：铝盐或铁盐在水中发生水解生成相应氢氧化物胶体，它可吸附天然水中悬浮物并破坏天然水中的其他带异电的胶体，使其聚沉，达到净化目的；
（2）明矾中铝离子水解生成胶体，使水中胶体及悬浮物沉淀下来，水的软化为降低水中钙、镁离子浓度，
故答案为：用混凝剂将水中胶体及悬浮物沉淀下来；除去水中Ca²⁺和了3²⁺；
（3）阳离子交换膜只允许阳离子自由通过，隔膜B和阴极相连，阴是阳离子放电，所以隔膜B是阳离子交换膜，阳离子向阴极移动，以得到得到淡水的目的，通电后，阳极是氯离子放电，生成氯气，其电极反应为：2Cl^--2e^-═Cl₂↑；
故答案为：B；2Cl^--2e^-═Cl₂↑；
（4）因海水中了3Cl₂的浓度较小，所以要经过富集这1过程：先加熟石灰形成沉淀：了3Cl₂+Ca（OH）₂═了3（OH）₂+CaCl₂，然后将沉淀过滤，接着将了3（OH）₂沉淀转化为了3Cl₂：了3（OH）₂+2HCl═了3Cl₂+2H₂O，这样就实现了了3Cl₂富集，将溶液蒸发结晶得到六水合氯化镁晶体（了3Cl₂•6H₂O）（这步是为了得到纯净的了3Cl₂），又因了3Cl₂ 易水解，为防止了3Cl₂水解的水解，加热六水合氯化镁晶体必须在HCl氛围下中进行：了3Cl₂•6H₂O

加热
.
了3Cl₂ +6H₂O．
故答案为：②④③⑤①；
（5）①第（5）着设备中先把N₂和H₂压缩，可使压强增大，有利于使平衡向生成氨气的方向移动，
故答案为：使平衡向生成氨气的方向移动；
②在第（3）着设备中用冷却方法分离出液氨，生成物浓度降低，可使平衡向正向移动，提高转化率，
故答案为：液氨；使平衡右移，提高氮气和氢气的转化率．

You are an indispensable part of my life.

Let me become an indispensable talent.

My friend and I
My best friend, Linda, is the same age as me.
In some ways, we look the same, but in other ways, we look different. For instance, she is serious. However, I’m opposite,I’m outgoing.I like making a lot of friends.Linda likes sitcoms.Maybe that’s because of her personality.
As for me,I can’t stand action movies. I think they are too exciting.When watching them, I feel my heart nearly jumping out of my chest.When talking about future, she says she is going to be a teacher. And in order to achieve her dream,she is going to study hard to get good grade.But for me,I am going to be a reporter so I will read more
And keep on writing articles.
Although we have so many differences, I regard her as my closest sister, that’s because whenever I meet any difficulty, she’ll try her best to help me out. A the saying goes,”A friend in need is a friend indeed.” I know its real meaning from her—my best friend,Linda.

1.As for me,confidence is the most important.
2.They should admit their wrong deeds.
3.I can make it.
4.(We should) face the problem with reason.
5.Cherish what you own now.
6.First of all,it is not a good phenomenon anyway.
7.As for this problem,I think we should solve it in this way.
8.Find all your potentials and abilities and use them in the work you do.
9.Don't care too much about the outcomes.
10.Reflect yourself from time to time.

Growing up, there are three things to shape my personality and character training played an indispensable role. That was the beginning of a small rise, people addicted to my whole movie. Entrance examination results came out, I was shocked, normally the top student of the class actually retreated more than twenty. Dream high school and I pass by. So my first real experience to the feeling of failure. The experience of failure in my heart left a deep imprint, so I never forget the meaning of diligence. On the junior high school, my physics class is the class representatives. Close examination, the teacher arranged for me to task for everyone finishing the test center. We looked at the rising scores, listening to everyone enthusiastic applause. Collective unity and dedication these words forever remain in my heart.

我似月亮番必不可少

在标准状况下每mol气体为22.4L,所以标况下44.8L=2mol=2*32g/mol=64g
有2NA个氧分子

解题思路：（1）液体的凝固点和沸点跟液体的种类、气压、杂质有关．种类不同，凝固点和沸点不同；气压增大，凝固点和沸点降低；有杂质掺入凝固点降低，但沸点升高．
（2）一切物体都具有惯性，质量越大，惯性越大；
（3）根据公式P=FV可知，汽车功率一定时，减小速度，可以增大牵引力；
（4）电动机的工作原理是通电导体在磁场中受力转动．

A、在汽车水箱k冷却水中加入防冻剂，是为1降低水k凝固点，防止结冰，故A错误；
6、惯性与质量有关，与速度无关，增大速度，可以增大车k动能，而不是惯性，故6错误；
C、汽车功率一定时，根据公式图=Fv可知，汽车在爬坡k过程中应减速行驶，才能增大其牵引力，故C正确；
g、汽车发动机启动时所用电机，其工作原理为通电导体在磁场中受力转动，故g错误．
故选C．
