h=1/2gt^2,h为高度,g为重力加速度,一般可认为g=9.8m/s^2,积雨云臃肿庞大,云底高度一般约在400-l000米,但各地气候地理等情况不同,那我们就按1000m计算吧,可得14

以我的英语水平加上在线翻译功能,勉强只能弄出这4句对话了.
虽然水平不咋的,但是我废了好大的劲,给分吧,你应该做的~

设按照规定的时间是x
(x+5)*90=(x+3)*100
9(x+5)=10(x+3)
9x+45=10x+30
10x-9x=45-30
x=15
准时是15分钟
路程是（15+3）*100=18*100=1800
速度：1800/15=120
他应以每分钟120米的速度走才能准时到达

演讲稿内容大致：
1.你学的内容
2.你感兴趣的生物知识
3.你学到了哪些你以前不知道的知识
4.你对生物前景的远瞻
5.各生物学家的贡献,由此结尾,你以他们为榜样.
内容详略自己安排,顺序也不是固定的.三五分钟的演讲稿很简单的,但也要自己完成啊.加油哦!

第一个问题,five minutes' walk; 分钟用复数,只是后面省略了表示所有格的S；
第二个问题,复数名词后所有格的名词用单数还是复数取决于这个名词本身是单数还是复数；你的例子中,是一个房间就用单数；如果不止一个就用复数；你并不一定非得使用所有格的形式,可以用OF

这句话文笔优美,情景交融,充满了梦幻朦胧的味道.作者充分调动视觉、嗅觉、触觉等多种感官,表现了自己看社戏途中的愉悦感受.

啥叫关于response的对话?
只要是对话,难道没有response吗?
不解题意.
可谈论的话题很多,包括：
•weather
What's the weather like?
•location / hometown
Where do you come from?
•jobs
What do you do?
•General family situation
How many people are there in your family?
Are you married?
•sports / hobbies
Do you like playing basketball?
•movies / books / music
Do you know Tom Cruise?

任何回答者都可以用：
Do you?
And you?
或其他方式 ask back.

1.电功率P=IU*√3=50*380*√3=33000W=33kW,每小时（连续运行）耗电33度.
2.按题意,每小时内运行时间为40分钟即2/3小时,每小时耗电：22度.比不间断时省电.
3.使用变频器启动不能省电,只有使用变频器不断调节工况时才能省电,具体省电多少根据工况而定.

应该包括,就好象你考试,60分以上算及格,也包括60分啊,所以五分钟以内,是包括五分钟的

LZ你什么都不给,怎么回答

When I got to the train station,the train has left since five minutes ago.
They have finished this work yesterday afternoon.
He stars doing homework as soon as he gets home.
I don't know how to solve that problem until he explains me twice.
This is the fifth time for them to fight last week
我也是学生,所以一般老师要求的短语我都有用到

分针5分钟走了一圈的5/60=1/12
一圈的周长为2×3.14×6=37.68
所以5分钟走了37.68×1/12=3.14厘米

依然 仍然 依旧
精心 细心

110/(2+3)=22（第一次相遇用了22秒）
300﹣22=278
278/(22*2)=6…3第二次开始44秒相遇一次（因为来回跑）
6+1=7
共相遇7次.

我也问过类似的问题,连接如下
http://zhidao.baidu.com/question/538711309?quesup2&oldq=1
交换两个比的位置,这算是不同的比例.

纸张里含微量淀粉,所以遇到淀粉变蓝,然后蒸发掉酒精后,大量的碘产生氧化作用,将纸氧化,产物是棕黄色的

1、曾经相遇,曾经相爱,曾经在彼此的生命光照,就记取那份美好,那份甜蜜.虽然无缘,也是无憾.
2、“一粒貌不惊人的种子,往往隐藏着一个花季的灿烂；一条丑陋的毛虫,可能蜕变为一只五色斑斓的彩蝶.因为,生命本身就是一桩奇迹.”
抱歉,只找到这么多

电感式的换启辉器,电子式的最好换镇流器 .家用的话个人觉得没必要用日光灯,换上灯座改灯管节能灯或者LED节能灯更方便

小红最快。求出他们三人每分钟做几题，然后通分，小红最大。采纳吧！

这个问题的速度和时间分别是指什么?不看问题,就看题目的话,我能想到的问题是走路速度与跑步速度比.如果是两个速度比的话,下面是解题方法
设走路速度v,跑步速度w,算匀速的.回来时的跑步时间X,全路程S
可列方程：
5V+8w=S
10v+xw=s
10+x-（5+8）=3.25得x=6.25
x带入之后得10v+6.25w=s
即10v+6.25w=5V+8w 得v/w=7/20

他们是同时出发的?如果是,如下
设小明走了x分钟
80x=60(x+8)
x=24
学校到运动场距离为24*80=1920（米）

小丽31*5=155小花46*3=138

没有,果园里没有玉米

小强提前五分钟到,赵明迟到十五分钟,小强等了二十分钟才等到赵明…

ENGLISH,SO I AM HAPPY
Dear teachers,students:
I am very happy to meet with you here today to tell you my speech is entitled "English,so I am happy."
English,spread to all over the world,people talk about memorization.Since my time in first grade began to learn English,I was not interested in it,but the third and fourth grade,when a sudden interest in reading in English every day,and even self-learning,to raise a lot of English results .
Now,my greatest interest is the time to see the English.Each weekend,I always find time to read English books or see on the English comic books,information books,and even outside the time when shopping,but also with some English information on the book,simply put it down.
Each school,I sometimes went to the library of books on English,a view that is 30 minutes,the harvest has been so many.
Once again,the summer vacation,I went to the United Kingdom.Where I see a lot of the city,this afternoon I have friends with the British dialogue in English,but also know a lot of knowledge of English,they also compliment away一extra-curricular knowledge of the English book.
I have often in the Monday and Tuesday,when listening to English tapes,one is 3 hours.Also frequently used sentence patterns learned review again,I learned to feel very proud.
The book in English class after school,but also extra-curricular English book out to read,every time I think:if these extra-curricular English read the end,learned that their English,reading and writing is not improved.Therefore,I,day and night,every day,reading,really English results improved reading and writing,I am more proud of.
I know that Rome was not built in a day.I believe that through continuous efforts to learn,one day,I can speak English very well.
Therefore,I am very happy of.
亲爱的老师们、同学们：
很高兴在这里跟大家见面,今天我给大家讲的演讲稿的题目是《英语,使我快乐》.
英语,流传到了世界各地,使人讲的滚瓜烂熟.自从我在一年级的时候就开始学起了英语,以前我是对它没兴趣,但到了三、四年级的时候,突然起了兴趣,天天都在读英语,甚至自学,英语成绩提高了不少.
现在,我最大的兴趣就是读、看英语.每次周末,我经常抽空看英语书或者看关于英语的漫画书、资料书,甚至到外面的时候,逛街的时候,还要带些英语资料书,简直爱不释手.
每次放学,我有的时候还到图书馆里关于英语的书,一看就是30分钟,得到许许多多的收获.
再一次暑假,我去英国.在那里我去看了很多的城市,下午我跟英国的朋友用英语对话,还懂得了很多英语知识,他们还送了一本英语课外知识的书.
我经常在星期一和星期二的时候听英语磁带,一听就是3个小时.还经常用学到的句型复习一遍,学会了我感觉非常自豪.
把课内的英语书学完之后,还把课外的英语书拿出来读,我每次想：要是把这些课外英语书读完了,学会了,那英语成绩、读写岂不是提高了.所以我不分昼夜,天天读,果然英语成绩、读写提高了,我更加自豪了.
我知道,罗马不是一日建成的.我相信,经过不断的努力学习,有一天,我可以讲英语非常好.
因此,我非常的快乐了.

甲、乙、丙三人跑步比赛,跑同一路程,甲用了一又二分一分钟,乙用了1.7分钟,丙用了六分之五分钟,请你帮他们排名次,看谁跑的快?
因为：5/6＜1又1/2＜1.7
所以：丙跑得快.（相同的路程,用时少的速度快）
2.甲、乙工程队修一条长720米的水渠,甲每天修20米,乙每天修25米,他们从两端同时开工,多少天后可以修完这条水渠?
720÷（20＋25）＝16（天）
3.有两块面积相等的平行四边形实验田,一块底边长80m,高55m,另一块底边长100m,高是多少米?
80×55÷100＝44（米）

Sleep is the first priority for me.Morning alarms won't work at all on me,they "snooze" every five minutes.In the end,I had to get up,and go to brush my teeth with my eyes still closed.After washing my face,I am more or less awake.Then I would be the most energetic one in the morning in my dorm.I often intentionally hum songs off the pitch,and that makes my dormies threaten to throw me out.

I HAVE A DREAM
Every body has a dream. There are many kinds of dreams. You may have a dream of being a superstar, to be a king of Kongfu, to be a millionair, to have a dog, to marry somebody.

m=lg20,2n=lg0.2
9^m=9^(lg20)=3^(lg400)
3^(2n)=3^(lg0.2)
所以原式=3^(lg400-lg0.2)=3^(lg2000)=3^(3+lg2)=3^3*3^(lg2)=27*3^(lg2)

如果轮船是在堪察加半岛附近海或者南半球低纬度海域往东越过180度经线,它就还在日界线的西侧,时间应该是,当天14点零5分；否则就是2月21日14点零5分.
如果是往西越过180度,日期应该加一天（23日或者22日）.
