小同学你是求什么的详解?X的值么
1/X-1/(X+2)=(X+2)/(X+2)*X-X/(X+2)*X=2/(X+2)*X=2/195
(X+2)*X=195
X²+2x-195=0
（x+15）（x-13）=0
可得X=-15或X=13

文言文状语后置概念
现代汉语中状语置于谓语之前,若置于谓语之后便是补语.但在文言文中,处于补语的成分往往要以状语来理解.
例如：《鸿门宴》：“将军战河北,臣战河南.”“战河南”即“战（于）河南”,应理解为“于河南战”.《促织》：“覆之以掌”即“以掌覆之”应理解为“用手掌覆盖（蟋蟀）”.
另外,还有定语置于中心词之后,修饰名词的量词放在名词之后等特殊现象,因不常用,因此按下不表.
状语后置的类型
状语后置有三种情况：
1、用介词“于”组成的介宾短语在文言文中大都处在补语的位置,译成现代汉语时,除少数仍作补语外,大多数都要移到动词前作状语.
例：青,取之于蓝,而青于蓝.（荀子《劝学》）
分析：此句中的“于蓝”介宾短语,前者应该移到“取”的前面做状语；后者“于蓝”介宾短语应该移到“青”的前面做状语,即译为“比蓝青”.
2、介词“以”组成的介宾短语,在今译时,一般都作状语.
例：具告以事.（《史记·项羽本纪》）
分析：“具告以事” ,即“以事具告” ,“以事”介宾短语做“告”的状语.
3、还有一种介词“乎”组成的介宾短语在补语位置时,在翻译时,可视情况而定其成分.
例：生乎吾前,其闻道也固先乎吾.（韩愈《师说》）
分析：“生乎吾前”中的“乎”就是介词“于”；“乎吾前”应该移到“生”的前面做状语.

顾名思义,磷脂双分子层是双层的.组成那双层结构的就是磷脂,我们可以形象的把它比喻成有两条尾巴的蝌蚪.它们占了磷脂双分子层的50%~60%.组成细胞膜的磷脂分子和蛋白质分子大都是可以运动的,这种结构特点,使细胞膜具有一定的流动性.

氧化还原反应是有元素化合价变化的反应.一般来说,置换反应,分解出单质的反应,单质与单质之间的化合反应都属于此类反应.在判断氧化还原反应能否发生时,要比较氧化剂和还原剂的氧化性和还原性的强弱,当氧化剂的氧化性较强时,能与弱还原剂反应,氧化性弱的只能与强还原剂反应.
不懂可以追问.

1.that 先行词是最高级修饰,关系代词用that
2.that 这里先行词是做定于从句的宾语 spent days ,不是做状语,所以不用when

状语从句
由从句担任的状语,在句子中可修饰谓语（或其它动词）、形容词、副词或是整个句子,它可以用来表示时间、地点、原因、目的、结果、条件、方式、比较、让步等.状语从句是一较大的语法项目,也是近几年高考题中常见的一个重要试点.高考中已考查了时间、让步、地点、条件、目的等状语从句,这些从句仍是今后高考热点,应作充分准备.同时对方式状语从句也应引起重视.
（一）时间状语从句
表示时间的状语从句可由when,as,while,whenever,after,before,till (until),since,once,as soon as (或the moment ),immediately,by the time,no sooner … than,hardly (scarcely) … when,every time等引导.

x05e.g.He is disappointed because he didn't get the position.
x05x05As it is raining,I will not go out.
x05x05Now that you mention it,I do remember.
（三）地点状语从句

e.g.Speak clearly,so that they may understand you.
x05She has bought the book in order that she could follow the TV lessons.
x05He left early in case he should miss the train.
（五）结果状语从句
x05结果状语从句是表示事态结果的从句,通常主句是原因,从句是结果.由so that （从句谓语一般没有情态动词）,so … that,such … that等引导.
x05e.g.She was ill,so that she didn’t attend the meeting.
x05x05He was so excited that he could not say a word.
x05x05She is such a good teacher that everyone admires her.
（六）条件状语从句
x05条件状语从句分真实性（有可能实现的事情）与非真实性（条件与事实相反或者在说话者看来不大可能实现的事情）条件句.引导条件状语从句的词（组）主要有if,unless,so (as) long as,on condition that,so (as) far as,if only ( = if ).注意：条件从句中的if 不能用whether替换.
x05e.g.If he is not in the office,he must be out for lunch.

x05x05So far as I know（据我所知）,he will be away for three months.

选 C
这是一个非限制性定语从句,用who 来指代前面说到的 his three sons,但因为放在介词of 的后面,所以用宾格 whom.
如果用them的话,这就是两个分开的句子,要么none前面用句号,要么none前面加个连词and

这个公式的作用是你只需要在A2单元格输入一个东西,这个公式就会自动找到它相关的信息.

楼上说的没错,
learning French = 学法语 ,
这里 French 是名词.
但就你的提问,正确的说法是
learning the French language
按英语规范,语言名词这种专有名词若含有 language
（即 French language,English language,Chinese language,等等)
前面要加冠词 the,这是因为在这情况下,French/English/Chinese 变成了形容词 .

What _does_the boy in a yellow coat_do__?He is a student.
这是问职业的固定句型

1 根据公式Vt^2-V0^2=2aL
因为汽车刹车后做匀减速运动,运动距离=22.5m,末速度为0,加速度最大为5
因此V^2=2*5*22.5
V^2=225
V=15m/s
行驶速度不能超过15m/s
2 距地面1.2m时,开始做匀减速运动,到达地面时速度为0,那么末速度为0,初速度为10m/s
根据公式Vt^2-V0^2=2aL
10^2=2*1.2*a
2.4a=100
a=41.7
3 因为飞机起飞做初速度为0的匀加速运动,起飞速度为50m/s,那么末速度为50m/s,跑道长100m,所以位移为100m
假设可以起飞,那么所需最小加速度为a
Vt^2-V0^2=2aL
50^2=2*a*100
200a=2500
a=12.5
而发动机最大加速度为5,因此无法起飞
假设所需初速度为V,那么
50^2-V^2=2*5*100
2500-V^2=1000
V^2=1500
V=38.7m/s

介词后跟动词ing形式,by是介词,所以后面是starting

你这是程序设计里的吧
for（i=0; i

protect ...from sth /doing sht .是固定的句型 .保护...不受.
这种句型还可以用 step/prevent ...from...sth/doing (sth) .

There is a well-know incident in one of Moliere's play,
(主句) （先行词）
where the author makes the hero express unbounded delight on being told that he had been talking prose during the whole of his life.（定语从句中的宾语从句）
（定语从句）

题目应该是(m+n)²-4n(m+n)+4n²
=(m+n)²-2×2n(m+n)+(2n)²
=(m+n－2n)²
=(m－n)²

C--on
drum表示鼓,按意思理解应该是安仔墙上的那种,under是“在.下面”,鼓不可能到了墙的下面,故排除A；in表示“在.里面”,一般表示一体的意思或包含的意思,如果鼓到了墙的里面了就没法敲了不是,故排除B,就只剩下C了啊!

两个都对,两个as的中间加形容词或者副词的原形,表示象或者如同什么什么一样

cos2 - sin2
= - 0.416147 - 0.909297
= - 1.32544

he did是整个句子的主句,what he thought was right是整个句子的从句,做did的宾语,所以是宾语从句.而what he thought was right.本身又是一个主从复合句,what he thought在这个句子中做主语,本身又是一个句子,所以是主语从句,was right是宾语从句中的从句

B
正常的语序是In China.Every student doesn't walk to school
所以转到前面就选B了

x立方-16x-x立方+9x+3x平方-27+5x
=(1-1)x^3+3x^2+(-16+9+5)x-27
=3x^2-2x-27

一般情况下,时间和条件状语从句的谓语动词一般用“一般现在时”表示“一般将来时”,用“现在完成时”表示“将来完成时”.例如： I will call you as soon as I arrive in Beijing. 我一到北京就给你打电话.（这是由as soon as引导的时间状语从句,从句中的谓语动词arrive是一般现在时,表示一般将来时,决不可用will arrive） As soon as I have finished this work, I will go home. 我一完成此工作,就回家.（从句中的谓语动词用现在完成时have finished,表示将来完成时,决不可用will have finished） If he comes back, please let me know.如果他回来了,请通知我.（从句中的谓语动词用comes back,表示一般将来时,决不可用will come back） 状语从句讲解和练习 状语修饰动词、形容词、副词或整个句子.通常由副词、介词短语、动词不定式、分词和从句等担当.例如： 1. Naturally , our grandparents were pleased to get our phone call . (副词) 2. We worked hard , from sunrise to sunset . (介词状短语) 3. To help my disabled aunt , I spend an hour working in her house every day . (不定式) 4. Seen from a distance , the farmhouse looked deserted . (过去分词) 5. I know how to light a camp fire because I had done it before .（原因状语从句） 状语的位置比较灵活,可以位于句首、句末或句中.enough用作状语修饰形容词和副词时必须后置. 状语从句主要用来修饰主句或主句的谓语.一般可分为九大类,分别表示时间、地点、原因、目的、结果、条件、让步、比较和方式.尽管种类较多,但由于状语从句与汉语结构和用法相似,所以理解和掌握它并不难.状语从句的关键是要掌握引导不同状语从句的常用连接词 和特殊的连接词即考点.现分别列举如下: 1． 时间状语从句 常用引导词：when, as, while, as soon as, before, after, since , till, until 特殊引导词：the minute, the moment, the second, every time, the day,the instant, immediately , directly, no sooner … than, hardly …when, scarcely … when I didn’t realize how special my mother was until I became an adult. While John was watching TV, his wife was cooking. The children ran away from the orchard(果园), the moment they saw the guard. No sooner had I arrived home ,then it began to rain.

Wherever you go, you should work hard. 3． 原因状语从句 常用引导词：because, since, as, for 特殊引导词：seeing that, now that, in that, considering that, given that. My friends dislike me because I’m handsome and successful. Now that everybody has come, let’s begin our conference. The higher income tax is harmful in that it may discourage people from trying to earn more. Considering that he is no more than 12 years old, his height of 1.80 m is quite remarkable. 4． 目的状语从句 常用引导词：so that, in order that 特殊引导词：lest, in case, for fear that,in the hope that, for the purpose that, to the end that The boss asked the secretary to hurry up with the letters so that he could sign them. The teacher raised his voice on purpose that the students in the back could hear more clearly. 5． 结果状语从句 常用引导词：so … that, such … that, 特殊引导词：such that, to the degree that, to the extent that, to such a degree that, He got up so early that he caught the first bus. It’s such a good chance that we must not miss it. To such an degree was he excited that he couldn’t sleep last night. 6． 条件状语从句 常用引导词：if, unless, 特殊引导词：as/so long as, only if, providing/provided that, supposing that, in case that, on condition that We’ll start our project if the president agrees.

Sometimes we teach our children the way our parents have taught us. 10. 状语从句的简化 状语从句的省略 状语从句同时具备下列两个条件:①主句和从句的主语一致,或从句主语为it；②从句主要动词是be的某种形式.从句中的主语和be动词常可省略.例如： When ( the museum is ) completed , the museum will be open to the public next year . He’ll go to the seaside for his holiday if (it is ) possible. 另外,比较状语从句经常省略.例如： I’m taller than he (is tall ). The higher the temperature (is), the greater the pressure (is ). 就状语从句而言,有时为了使语言言简意赅,常常将状语从句进行"简化".状语从句的"简化"现象在口语中较为普遍,而且在高考中的复现率也较高.因此,有必要对其进行全面、透彻的了解. 状语从句的"简化"现象常存在于以下五种状语从句中:①由if, unless等引导的条件状语从句;②由although, though, even if / though等引导的让步状语从句;③由when, while, as, before, after, until / till等引导的时间状语从句;④由as, as if等引导的方式状语从句;⑤由as, than等引导的比较状语从句.下面针对这五种情形作一归纳. (1)当状语从句的主语是it,且谓语动词是be时,it和be要完全简化掉.例如: If (it is) possible, he will help you out of the difficulty.如果可能的话,他会帮你摆脱困境. You must attend the meeting unless (it is) inconvenient to you.除非情况对你来说不方便,否则你必须出席这次会议. (2)当状语从句的主语和主句的主语一致时,从句可以将主语和be动词简化掉.常用于以下几种情形: a.连词+形容词 As (he was) young, he learned how to ride a bike.他小时候就学会了骑自行车. Whenever (she is) free, she often goes shopping.她有空就去逛商店. Work hard when (you are) young, or you'll regret.少壮不努力,老大徒伤悲. b.连词+名词 While (he was) a young boy, he was always ready to help others.他在孩提时代就乐于助人. Although (he was) a farmer, now he is a famous director.尽管他曾是个农民,而现在是位著名的导演了. c.连词+现在分词 As (she was) walking along the river bank, she was singing a pop song.她沿着河堤边走边唱着流行歌曲. Although (he is) doing his best in maths these days, he has still got no good marks.尽管近来他一直在学数学,但他仍然没有取得好成绩. d.连词+过去分词 He won't go there with us unless (he is) invited.除非受到邀请,否则他不会和我们一道去那里. The concert was a great success than (it was) expected.这场音乐会出乎意料地取得了巨大成功. e.连词+不定式 He stood up as if (he were) to say something.当时他站起来好像要说什么.He wouldn't solve the problem even if (he were) to take charge.即使他来负责,他也解决不了这个问题. f. 连词+介词短语 She looked anxious as though (she was) in trouble.她看上去很焦急,好像遇到了麻烦. He had mastered the English language before (he was) in the USA.他到美国之前就懂英语了. 注意:当从句主语和主句主语不一致时,从句部分要么用完全形式,要么用独立主格结构来表达.(=The meeting over,

c 都是前一个数字加后一个数字,在减一,不信试试

独立主格结构
如果非谓语的逻辑主语与句子不是相同的,则要用从句或分词独立主格结构来表示.独立主格结构的构成:主语+ to do / done/ doing / (being) +adj / adv/ prep / n.例如：
Here are the first two books,the third to come out next month.
She appeared in front of us,her face bright with joy.
x05Weather permitting,we will go to the Center Park.或:If weather permits,we ….
Her mother (being) ill,Mary stays at home looking after her.

求给分

“独立主格结构”也叫“独立结构”,把复合句变成一个简单句.它与真正的句子的不同之处：句子要有谓语动词,而独立结构是“非谓语动词”,即,逻辑谓语,或其它词性,有以下种类：注：括号表示可以省略.
1) ing动词作逻辑谓语 （表示主动的含义）
e.g.The storm having damaged everything,many people became homeless.
John arriving home,Mary asked him to dine.
There being nothing to do,we played game.(there be)
Time permitting,I can finish in one hour.(If I am given enough time …)
2) ed 动词作逻辑谓语 (表示被动的含义)
e.g.He rushed into the room,his head (being) covered with snow.
All things (being) considered,he has done his best.
The job (being) finished,we went home straight away.
The first problem (being) solved,the second will be found easier.
The table (being) set,we began to dine.
So much money having been spent,we haven’t seen any good result.
3) 不定式动词做逻辑谓语 (表示将来的含义)
e.g.I now pay you half the sum,the other half to be paid next month.
The plan was that the two parties should first reach an agreement on the basic principle,the details to be worked out later.
4) “主系表”句型里的形容词或其它词性
e.g.The children were watching the acrobatic show,their eyes (being) wide open.
The weather (being) fine,we went out for a walk.
He sat there,his face (being) serious and his attention (being) steady.
5) 以上部分都可以在前面加用“with” “without”
e.g.
a) V-ing
With night coming on,we hurried home.
I read newspapers with the morning sun shining through the window.
Finally she came without anyone accompanying her.
I stole away without anyone noticing me.
b) V-ed
With the tree planted,we get tired.
With the tree grown,we get more shade.
They sat face to face,without a single word said.
He enjoyed listening to music with his eyes closed.
c) To-V
What is to become of Miss Hilary now,with her parents (being) gone so quickly,and with nobody to look after her?x09
D) 其它词性
He went away with the light (being) still on.
The little girl came to me,with eyes (being) red.
