|采纳率100%One may ask what is a good friend? Webster Dictionary defines good as having moral excellent and well behaved. Friend is defined as one who is understanding, caring, and shows concerns for others.
When you combine both of these words together you have created a good friend. A good friend must be a very understanding person.
What is meant by understanding is that he knew the feelings and thoughts of your situations. Whenever you felt as if you could not make it anymore and depression had weigh you down He could relate to how you felt. He would ask you to come to church and join him.
If someone hurt you or said something wrong that made you cry, he would cry as if they had spoken to him. He respected your feeling as well as your body.
you would also find answers to questions he'll have to finish at the end of each chapter. write down the questions and page number for him to go back and write down the answers.
In conclusion,We must use time as a tool, not as a crutch. As I end I'll like to recite a poem I wrote to him.
Friendship
Friendship with you is what I value most.
I hope that I can keep this, and chemist it to the utmost.
No matter where we go, or where we might be,
There is something that we should both remember that we're friends,
In friends we have grown a long time.
Trying to read each other's mind.
Trying to figure out what's right or wrong.
Trying to help each other to be strong.
Trying to overcome obstacles and hold on.
Friends are we; right to the heart; even if we grow apart
I'll still hold a special place for you in my heart.
Even if we never meet again, just remember
That you'll always be my friend, because a true friend's Friendship never ends1年前查看全部

Cq土木 共回答了22个问题
|采纳率100%(不是原创)As far as I’m concerned,prevention is superior to punishment in ensuring citizen safety.After all,if crimes could be prevented successfully,no one would ever get hurt,and there is no necessary for punishment.Punishment is what takes place when prevention fails,and is therefore rendered useless when prevention succeeds.Thus,to ensure citizen safety,the best place to start is with prevention.Although prevention is much harder to implement than punishment,there are still many ways crime could be prevented.
For example,policing hot spots,areas of known criminal activity,will help to decrease the number of criminal events in those areas.Also,community policing efforts can be made to capture known criminals,and secondary prevention techniques can be put into use:focusing on at risk situations such as youth who’re dropping out of school or getting involved in gangs.All of these measures can reduce crime,and in the future,could possibly even prevent crime.In conclusion,prevention is the better alternative in ensuring citizen safety.1年前查看全部

|采纳率87.5%when est meet west.
this is an culture-exchanging epoch,when no ester can escap from the impact of western culture. being a Chinese, what should we do to achieve the greatest benefit for our nation and race? shall we resist it , like a stubburn ostrich struggling to stick head into sand and pretending nothing happened,or embrace it , like a young plant absurbing new fresh nutrition from the earch and landing on our feet?
i personally prefer the later. any wise Chinese will agree with me. surely it is necessary and inevitable to forgo something to get new stuff.however it does not mean no good thing comes from our culture and we need to abundan them all, of course. contrarily, it is rational and reasonable to get a tradeoff between keeping our original culture and accepting new western culture. someone may have started to grumble already :"all your opinion and talking are nonsense, there is nothing we can do to accept western culture. it is too far from us, who are just some regular citizens living in a small town" .actully there is something we can do . we can start with accepting the phenomenon of emigration and overseas students instead of soaring grievance.
anyway, it is meaningless to act as a young cynic and discriminate anyone from overseas, despite of his/her nationality. If we really hope our country to become more powerful and thriving , it is a good beginning to abundon some old Chinese tradition like shouting slogans and writing english composition assignment and take new western culture like focusing on actions.

- 大学英语阅读,求解The earth is not the only body that travels around
大学英语阅读,求解
The earth is not the only body that travels around
the sun. With it are eight other planets (行星), fellow members of the sun's
family.
Two of them are nearer while the other six are farther from the sun than the
earth is. The farther they are, the longer trips they make around the sun.
People noticed long ago that these traveling bodies moved around in the sky in
fixed paths. It is a force called gravity (重力) that holds them in their paths.
We know that every little bit of matter in the universe (宇宙) pulls upon every
other bit of matter. Because the sun is so large, the pulling between the sun
and the planets must be very great. If it were not for this pulling, the planets
would fly off into space. In the same way there exists a pull between the earth
and the moon, which keeps the moon traveling in its orbit (轨道) around our
planet, the earth. Gravity holds you to the earth's surface, and pulls the ball
you throw into the air back to it. Of course, the ball also pulls on the larger
earth but the earth is so much larger that the pull is not noticed.
Now remember that large bodies bring to bear a greater pull on any body that
contains less material. But each object in the universe, no matter how small,
pulls on all other objects to some degree.

Most People Travel because they want to see their families and friends who live far away. For me, I love traveling the world, I feel a rush of adventure and love meeting new people and I suppose I love getting to play the foreigner. I also like experiencing the new, new different things that you simply cannot get anywhere else. I want to learn others cultures. I want to see the difference between our culture and other cultures. I want to learn others culture because for me traveling is fun while learning. One particular thing about the culture is the food. I want to know how food is prepared and how it is done. Obviously, I love to eat.
The most important reason is that I want to see all beautiful scenery of different countries. I would like to take pictures because it serves as souvenirs.
Traveling is not only for rich people. Whether you are poor or in the middle class, you can travel as long as it fits your budget. Some travel for their goals, some travel for fun and relaxation and some travel for experience.

|采纳率94.7%Ag2O(s) = 2Ag(s) + 1/2 O2(g)
1、估算Ag2O最低分解温度
ΔrSmθ = ΔrHmθ / T
因为一般情况下,ΔrHmθ和ΔrSmθ不随温度的变化而改变,所以可以利用查表查到各物质的生成焓和标准熵(298K数据)求出:
ΔrHmθ = 2ΔfHmθ (Ag,s) + 1/2ΔfHmθ (O2,g)- ΔfHmθ (Ag2O,s)
= 0+0+ - ΔfHmθ (Ag2O,s)
= - ΔfHmθ (Ag2O,s)
ΔrSmθ = 2 Smθ (Ag,s) + 1/2 Smθ (O2,g)- Smθ (Ag2O,s)
以上可以通过书上附表查到,代入计算可得.
2、求平衡常数Kθ
ΔrGmθ = - RT ln Kθ
ΔrGmθ = ΔrHmθ - T ΔrSmθ
ΔrHmθ 和 ΔrSmθ在1中已经计算出,代入即可.
3、求p(O2)
由化学方程式得:
[p(O2) / pθ ]^1/2 = Kθ
Kθ已在2 中求出,代入即可求得氧的分压,pθ为标压.1年前查看全部

|采纳率93.8%In order to build a civilized city,we students should try our best to behave well in the activities.
It's a good habit to keep our clothes clean and tidy.Our city should be kept clean every day.Don't throw litter or spit about.It's good manners to say "Thank you" and "Please" and so on.We should never say dirty words.Be friendly to others and always ready to help the people in need.For example,when we are on a bus,we should give our seats to the old and the women with babies.We should also obey traffic rules.When the traffic lights are red,we should stop.And we'd better not talk or laugh loudly in public.
If everyone behaves well,our city will be more beautiful and more attractive.1年前查看全部

|采纳率90%suggest有两个最常用的意思,
一个是建议,如是这个意思,那么后面的宾语从句要使用虚拟语气,就是从句的谓语用should do的形式,而should可以省略.
另一个是“表明”,后面的英语从句正常,不需要虚拟语气.
这个句子中,是表明的意思 ,翻译为:我们关于地球已知的知识表明,只要适当的条件存在,生命就会出现.
后面的wherever虽然是个让步状语从句,但是有点“条件”的意思,而英语中这用带有条件意味的状语从句,其时态通常按照“主将从现”的条件句来处理,所以才选择了D!

|采纳率90.5%We have two
different faces we can show the world.We can smile,or we can frown.The face
we choose to put on each day affects us a lot.Smiling is,of course,the
better way to live.
Smiling keeps us
healthy.When we frown,we tighten up our faces and our bodies become tense.Our
bodies function better when we are relaxed.A smiling face is a relaxed face.
Smiling makes us feel good,and keeps our bodies working smoothly.Smiling also
makes us look good.No one likes to look at a person who is frowning.Such
people make us want to turn and walk away.If we wear a happy face,then the
world will be more cheerful.Smiling is also important for success in the
business world.A smiling salesman will far outsell a competitor who frowns.A
smiling doctor will help his patients feel at ease and a smiling lawyer will win
the hearts of the jury.
In brief,smiling
improves our lives in every way.As the song says,“ When you’re smiling,when
you’re smiling,when you’re smiling,the whole world smiles with
you.”

It is really my honor to have this opportunity for an interview,
I hope i can make a good performance today. I'm confident that I can succeed.
Now i will introduce myself briefly
I am 26 years old,born in shandong province .
I was graduated from qingdao university. my major is electronic.and i got my bachelor degree after my graduation in the year of 2003.
I spend most of my time on study,i have passed CET4/6 . and i have acquired basic knowledge of my major during my school time.
In July 2003, I began work for a small private company as a technical support engineer in QingDao city.Because I'm capable of more responsibilities, so I decided to change my job.
And in August 2004,I left QingDao to BeiJing and worked for a foreign enterprise as a automation software test engineer.Because I want to change my working environment, I'd like to find a job which is more challenging. Morover Motorola is a global company, so I feel I can gain the most from working in this kind of company ennvironment. That is the reason why I come here to compete for this position.
I think I'm a good team player and I'm a person of great honesty to others. Also I am able to work under great pressure.

大学英语!阅读理解(2)!
My mind went numb when I saw the gun pointing against the car window as we pulled out of the garage:This can’t be happening to me.Then I felt the gun,cold,against my head,and I heard my friend Jeremy saying,“What do you want?Take my wallet,” but at the time I thought of nothing.I remember being vaguely annoyed when the gunman pulled me from the car by the hair.I remember the walk to the house ---- Jeremy,me,the two men with two guns.I remember the fear and anger in the gunmen’s voices because Jeremy was being slow,and I was wondering why he was being so slow.I did not realize that Jeremy had thrown the keys into the shrubbery.But I remember the sound of the gun hitting Jeremy’s head and the feeling as the man who had hold of my hair released me.And I remember the split second when I realized he was looking at Jeremy,and I remember wondering how far I could run before he pulled the trigger.But I was already running,and upon reaching the car across the street,I didn’t crouch behind it but screamed instead.I remember thinking there was something absurdly melodramatic about screaming “Help,help!” at eight o’clock on a Tuesday evening in December and changing my plea to the more specific “Help,let me in,please let me in!” But the houses were cold,closed,unfriendly,and I ran on until I heard Jeremy’s screams behind me announcing that our attackers had fled.
The neighbors who had not opened their doors to us came out with baseball bats and helped Jeremy find his glasses and keys.In a group they were very brave.We waited for the cops to come until someone said to someone else that the noodles were cold,and I said politely,“Please go and eat.We’re O.K.”
I was happy to see them go.They had been talking of stiffer sentences for criminals,of bringing back the death penalty and how the President is going to clean up the country.I was thinking,they could be saying all of this over my dead body,and I still feel that stiffer sentences wouldn’t change a thing.In a rush all the rage I should have felt for my attackers was directed against these contented people standing in front of their warm,cozy homes talking about all the guns they were going to buy.What good would guns have been to Jeremy and me?
46.When the writer saw the gun pointing against the car window,______________
a)she felt very much afraid.
b)she felt very angry.
c)she lost consciousness.
d)she lost the power to think about what was happening.
47.When the gunman pulled her from the car by her hair,______________

a)would sound as if she were mad.
b)would sound as if she were giving a false alarm.
c)would sound foolish and unreal.
d)would not sound emphatic enough.
