路上有一排路灯,相邻两个路灯之间相隔5米,小明从第一个路灯走到最后一个,共走了80米,请问路上共有多少

50÷10+1=6棵

Jane is still on the way to school

1. I ran into Uncle Li on my way to school. （run into 偶然遇见， come across 偶遇）
2. There is not enough water on the earth.
on earth与on the earth
on earth有三层含义和用法：
作“到底”或“究竟”解，置于 what，when等疑问词之后，以加强问句的语气。例如：
①What on earth is it？这到底是什么东西？
②Why on earth did you tell a lie？你究竟为什么要说谎？
作“当今”或“世界上”解，用于最高级之后，以加强语气。例如：
He said，“I'm the happiest man on earth．” 他说：“我是世界上最幸福的人。”
用于否定词之后，作“一点儿也不”解，以加强否定的语气。例如：
It's no use on earth．这一点儿也没有用。
He said，“Nothing on earth can change my mind．” 他说：“无论什么也不能改变我的主意。”
on the earth作“在地球上”解。例如：
We live on the earth．我们生活在地球上。

第三个人是老实国的人，只有这个结果是可以成立的。

14-12=2（小时）
2×3÷（5-3）=3（小时）
3+2=5(点）
乙在5点追上甲
设x小时后追上甲
3x+2×3=5x
6=2x
3=x
x=3
3+2=5(点)

大雾天气,你根本分辨不清15米之外的情况.

Friday that day, suddenly overcast, I have no umbrella, I go home in the rain, the road have a classmate sent me home.

有A,B两段路,A段路厂600米,B段路长540米,在这两段路上等距离安装路灯,要在这两段路的的终点必须按一盏灯,那么至少需要安装几盏灯?算式
600、540的最大公因数是60
600÷60+1+540×60+1
=10+1+9+1
=21盏

C

your words is the light before my feet,as well as the brightness on my way

（1）
12-10+7=2+7=9（小时）
答：该汽车路上用了9小时。
（2）
414÷9=46（千米/小时）
答：该汽车平均每小时行46千米。
祝你开心

i got lost on the way to Beijing yesterday

金秋时节雨纷纷
路上行人欲断魂
孤身远影人踪灭
唯见少年道旁留
离离路边草
青翠新雨后
人生自古谁无厄
咬定青山不放松
任尔东西南北风
不是律诗,文绉一点的打油而已.望有裨益

这属于平抛运动
下落的高度为：h=Lsin30=20
h=gt^2/2
解得t=2
水平方向的距离为：Lcos30=vt
起跳的速度v=10*根号下3=17.3
2.运动员的速度与斜面平行时,离斜面最高
你可以把山坡看成水平面,它做斜抛运动
垂直斜面向上的速度为vcos60=17.3/2
此方向的加速度为gcos30=5*根号下3
所以v^2=2as
s=v^2/2a=75/(2*5*根号下3）=4.33

jim can meet an old man every day on his way to school.

在b从(b的)下一个路口离开时,总共经历的时间为行进的20s和停留的30s,在这50s内a一共走了250m,所以a和b的间距变为200m+200m-250m=150m
设题目中给出的b所处位置为第x个路口,分类讨论如下
1.若x后面路口数小于等于3,则a和b不会相遇
2.若x后面路口数等于4,则a和b正好相遇于最后一个路口,此时b正好要从这个路口出发.
3.若x后面路口数大于4,在第五个路口,b停留10s时,a到达,第二次相遇;b出发时,a在b前面100m,这样a和b会同时到达下一个(六)路口,第三次相遇;这次b出发时,a在b前面150m,在以后的路程中,b就再也赶不上a了,故不会再相遇.

解；当汽车的前窗玻璃倾斜时,车内乘客经玻璃反射成的像在车的上方,而路上的行人是不可能出现在上方的空中的,这样就将车内乘客的像与路上行人分离开来,司机就不会出现错觉．若车玻璃是竖直的,这样车内的乘客经玻璃的反射成的像就在车的前方,这样司机在驾驶的时候就会产生错觉,影响驾驶

下雨天的路面通常相对较滑,原来车子质量相对较小,对地面的压力也相对较小,所以驱动轮的摩擦力较小而不能使车子得到较大的牵引力（牵引力实质是驱动轮受到的向前的摩擦力）,车子难以开动.
　　当车上多坐十几个人后,车子与人的总质量大大增加,对地在的压力也大大增加,所以驱动轮的摩擦力受到的向前的摩擦力（即牵引力）也大大增加,从而能使车很快开出了路滑的地方.

盐的成分是氯化钾,雪的成分是水.氯化钾是极溶于水的化学物质.氯化钾溶于水后生成氯化钾水溶液,其中含有钾离子和氯离子.
水要结冰时,有氯离子和钾离子存在时,氯离子和钾离子会破坏水的结晶网状结构,使水不能结冰.
也就是说,盐能使雪不结冰
其实雪是在不断融化和凝固的,只不过二者速度相等,所以始终保持固态!撒上盐以后,雪周围的水就便成盐水,因此就凝固不了了!这样雪就会不断融化,而不能再凝固回去,所以就越来越少了!
大学的溶液知识中有一个重要的性质：稀溶液的依数性. 它的两个重要的表现是：稀溶液的凝固点降低,沸点升高. 具体的原因是根据拉乌尔定律的一个公式推导出来的
实验表明,如果食盐溶液里含有20%的盐分,它的冰点就会降低到-16℃.
同样,不同金属制成的合金的熔点往往比组成中熔点最低的那种金属的熔点还要低.
再说,盐的代价便宜,并且没有污染(不像煤).因此,下雪时,经常给路面撒盐,防止雪水结冰.

只有几个支路并联才称为并联电路,才有干路和支路之分.只剩一条支路根本就没有干支路之分.你后一句是对的.

清明
杜 牧
清明时节雨纷纷,
路上行人欲断魂.
借问酒家何处有,
牧童遥指杏花村.
诗的首句“清明时节雨纷纷 ”,点明诗人所置身的时间、气象等自然条件.清明节为唐代的大节日之一 ,这一天 ,或合家团聚,或上坟扫墓,或郊游踏青,活动多样.但是杜牧在池州所过的清明节却不见阳光,只是“天街小雨润如酥”,细雨纷纷.
第二句“路上行人欲断魂 ”,由写客观转入状摹主观,着重写诗人的感情世界.他看见路上行人吊念逝去亲人,伤心欲绝,悲思愁绪.
“借问酒家何处有”一句 .诗人融景伤怀至极,而又要冒雨赶路,雨湿衣衫、春寒料峭.诗人希冀借酒消愁.于是,他便向人问路了.
结句“牧童遥指杏花村 ”,点明了上句诗人问路的对象 ,“牧童遥指”把读者带入了一个与前面哀愁悲惨迥异的焕然一新的境界,小牧童热心甜润的声音,远处杏花似锦,春意闹枝,村头酒旗飘飘,真有“柳暗花明又一村”的韵致诗的前两句创造了一幅凄迷感伤的艺术画面,后两句则创造了一幅鲜明生动的画面,前抑后扬,对比交错,相映成趣.与诗人的感情脉搏一致.

1,内容上加也许,丰富了文章的主题,使中心明确,衔接后文的可是,用我们经历过的挫折来表现在我们自己手中的摆渡的船的重要性.在结构上承接上文开启下文.
2,人有悲欢离合,月有阴晴圆缺,此事古难全.

在放学回家的路上,我听到了清脆悦耳的鸟鸣.循着声音抬头看,发现有两只可爱的小鸟在欢快地唱歌,真的好美妙~

是的.两站之间车票上的始发站和终点站不同,但票价相同.
比如说,北京至上海与上海至北京,是两张不同的车票,但票价是相同的.
车票,就是从五个站中,任取两个进行排列.我们用1,2,3,4,5表示5个站
（1,2）,（2,1）就是两张不同的车票,票价相同.
所以,车票数是排列：5取2的排列,5×4=20种.
车票价,5取2的组合：5×4÷2=10种.

(1) the site farewell to collecting from working hours, the sun has just jumped into the sea, the after glow of sunset dyed the good wine red.
(2) meet an evening walk in on the way back to the article, who is out for a walk after supper of city dwellers, leaving behind him a share of good smell of soap flavor. Farewell to think, is it well with city dwellers will, old people is not the dark won't eat dinner.

In the remaining two dollars, pass by small supermarket, turn to go in and spend a half jins of bulk sorghum, Britain delighted to go home.
(4) living in the basement of the sultry farewell, 4 piece of paper put aside a ZhuTa tiles is his bed, take off the paint two square stool is farewell to pick up, a square stool be him as the dinner table. Farewell to the rice cooker burn with dinner. And table stool on the ground to move the road, prepare to eat dinner. The table has two bowls of two pairs of chopsticks, carefully unlock LuWei, bend, struggled to breath, ah, delicious! ([B] farewell to sit down, first to the opposite in the empty bowl pour a bit wine, give your bowl pour a bit, since the bowl to the empty opposite, mumbling way: "the child he niang, today is the Mid-Autumn festival, I bought meat, bought food, you also drink wine solution. It refreshment") and pick up a piece of essence, pass to the opposite: "children he niang, to eat some meat, this meat can be fragrant." Farewell to feel his women smiling opposite to pick up the meat, he said: "his dad, you're a day, quick drink bar." Farewell bow sniffed the wine, closer to bowl along, squint, took a sip and oral swings in the swing, slowly swallow, open your mouth, one breath, oh, it's great!

(5) to eat laozhao.laozhao irony is drinking, enjoying his dinner, the distance spread familiar song: the moon 15, as in my hometown, as in the border, the quiet night, you also miss, I also think about. Farewell to soft heart in a big mess, with his eyes misty also follow gently hum up.

下午2点当乙到达B地时,甲应在A地前方11*（14-11）=33千米处
因为A,B两地间的路程为21千米
所以此时甲,乙间距离=33-21=12千米
因为甲,乙的速度差=14-11=3千米/小时
所以乙需要12/3=4小时才能追上甲
即在甲过A地的3+4=7小时后乙能追上
即乙在离A地7*11=77千米处追上甲

可以设甲每小时行a千米,所以乙每小时行a+2千米.即8a=7（a+2),解得a=14.
（14+2）乘以7=112

莫听穿林打叶声,何妨吟啸且徐行.竹杖芒鞋轻胜马,谁怕?一蓑烟雨任平生.
