“这个周末”,我的理解是指刚刚过去的周末,所以,我在翻译这句话时用了过去时.
How busy I were this past weekend!

we need take a good rest over this weekend.

科学探究包含有七个要素:提出问题→_______________→设计实验→__ ____________→分析和论证→_______________→交流
1、声音是由发声体的 而产生,它需要靠 传播,不能传声.
2、声音在固体、液体、气体中传播速度的快慢情况是
3、声音在空气中传播速度是 m/s= km/h
4人耳听到回声的条件是：回声比原声晚 S以上或人距离障碍物至少要 米
5、乐音的三要素：、 、
6、音调高低与 有关；响度的大小与 和 有关；闻其声而辨其人是因为各人的 不同.
7、人耳听到声音的频率范围大约是每秒 次至 次.
（1）、噪声是用 （符号） 来划分声音强弱的等级.
（2）、较理想的安静环境是 .
保护听力,噪声不超过 ；保证工作和学习,噪声不超过
8、噪声 ；保证休息和睡眠,噪声不超过
①、
（3）、减少噪声条件 ②、
③、
1、温度：表示物体 单位是
2、测量温度的工具：,工作原理是
3、温度计的使用：使用前要观察它的 ,认清它的 .
使用时要将温度计的玻璃泡 被测液体中,不要碰到 和 ,待温度计的示数 后再读数,读数时 继续留在被测液体中,视线要与液柱上表面 .
4、物质存在的三种状态：、 、
5、六种物态变化
八年级物理光现象重要知识点
光源：能够发光的物体
光的直线传播：同种均匀介质中,光是沿直线传播的.
光速：C=3.0×108m/s
色散：复色光分解成单色光的现象
光的三原色：红、绿、蓝
颜料的三原色：红、黄、蓝
任何物体的表面都会反射光
光的反射定律:反射光线与入射光线、法线在同一平面内；反射光线和入射光线分居法线的两侧；反射角等于入射角.
光路是可逆的
反射种类：镜面反射、漫反射
平面镜成像特点：物像关于镜面对称
即：物与像距平面镜的距离相等,物像连线与镜面垂直,所成像是正立、等大的虚像.
像的性质：等大、正立、虚像
虚像：是反射光线的反向延长线会聚所成的
应用：改变光路、成像
光从一种介质斜射入另一种介质时,传播方向一般会发生变化,这种现象叫光的折射.
光从空气斜射入水中或其他介质中时,折射光线与入射光线,法线在同一平面上;折射光线和入射光线分居法线两侧;折射角小于入射角;入射角增大时,折射角也随着增大;当光线垂直射向介质表面时,传播方向不变.光从空气斜射入水中时,折射角小于入射角.
垂直入射时传播方向不发生改变.
红外线的应用：红外线遥控、热效应强、红外线穿透力强
紫外线的应用：荧光效应、生理作用、化学作用
声现象
本章学习的声现象包括声音的发生和传播；音调、响度和音色——即乐音的三特征；噪声的危害及控制等三部分内容经过学习应对声音的产生、传播及其特点、特征有一定的了解,知道噪声的危害、避免或减弱的方法会利用声学知识有效地控制噪声,进行环境保护,能解释许多生活中遇到的相关现象
核心知识
本章学习的内容,见下图所示.需要说明的是：一、要突出本章重点；二、多与生活相联系.特别关注说理或简答题中考中其实未必会考声现象的相关知识,其实重要的都是通过学习努力掌握物理学科的学习方法,为后面的学习奠定良好的基础.
声源:1声音三特征:1音调
2响度
3音色
2声音的传播:1音速
2反射
3声音的分类:1乐音
2噪音:1来源
2利弊
3控制

五分之七?
七分之五吧.
设：这本书一共有x页
5/7(七分之五)x=35
则 x=49

would like to enjoy.

My friends will come this weekend

1、35÷ =49（页） 2、8÷ =11.4（千米/秒） 3、5200÷ =5500(km)

Helen going to do this weekend?

I am very busy this weekend ,I visit my uncle and play computer in the moning.At noon I and my friends to write homework.l sleep in the afternoon.
this is my weekend.
这个周末我很忙,我去拜访我的叔叔和玩电脑在早上.中午我和我的朋友一起写作业.我在下午睡.
这就是我的周末.

“I had a good time last weekend.
this weekend是指马上要到来的那个周末,用在这里是错误的”
这个网友说的有道理,但我认为说话的时候还是在“这个周末”的,所以我的答案是
I am enjoying this weekend.

last weekend
last weekend ,it was fine day

35乘7分之5等于49页
好简单啊---------

This weekend is my father ′s birthday .I pian to give him a birthday party .I hope him can get happy .

求你了!

唉,又到星期天了!为什么一年当中有那么多星期天呢?我这一生最讨厌星期天了,因为这个日子里我又要对付那些五花八门的补习班和堆得象山一样的作业.
早晨刚7点（大家注意,这是星期天的早晨呀!）我刚刚听到一连串的“快起来的”催促声.根据以往的经验,此时不管我咋困,咋不愿意,也不能留恋着温暖的被窝了,英语补习班已经在向我招手了.
晃晃荡荡地走进英语补习班,我还没从梦境之中挣脱出来.老师讲的单词,我是左耳听,右耳冒.当老师叫我起来读单词,还是同桌撤了一下我的衣角我才清醒过来,站起来竟然还问了一句“什么”,惹得全班同学哄堂大笑.老师当场把我指责得无地自容.虽然脸上火辣辣的,但是英语课还是混过去了.
出了英语班,我又进了作文班.
出了作文班,我又进了奥数班.
下午,按照惯例,只有做完老师布置的作业我在家才有发言权.于是我抓紧写了起来.妈妈坐在我身边的小板凳上,一边织毛衣,一边监工似的不时把怀疑的目光投到我身上.经过艰苦的奋斗,我终于在4点10分讲座也搞定.我问：“妈,我能出去玩会吗?”妈妈一听,瞪着眼睛又板着脸说：“不能,赶快把《数学同步活页》做完,否则别想出去玩!”啊,我晕倒!无奈之下,我只好提起笔来继续写啰.写完活页已经是5点30分了,妈妈宁愿把晚饭推迟,也要守着我把活页写完.
爸爸回来了,对我神秘一笑：“我给你带了一样好东西!”“什么?是洋娃娃还是零食?”“都不是,是《黄冈密卷》!”啊!看来我今晚又要奋战一晚了.
哎!这星期天可真难敖啊!

作为一名中学历史教师,我曾带领班级学生前往北京航天城参观学习,那次活动极大地激发了孩子们对宇航事业的热爱和向往.是啊,中国航天事业经过了50多年的发展,取得了辉煌的成就,从古中国的“嫦娥奔月”的登月幻想起就开...

I had a great time this weekend

This weekend I have the time, may see the fashion show on Sunday.
My parents probably going to Shanghai next week.
He will go swimming rather than play soccer.
I will return home within five minutes.
I forgot to bring tennis rackets, but I do not play tennis is unlikely.

白居易的《问刘十九》
绿蚁新醅酒,红泥小火炉.
晚来天欲雪,能饮一杯无?
新酿的绿米色酒,醇厚,香浓,
小小红泥炉,烧得殷红.
天色将黑,大雪欲来,
我的朋友,能不能否共饮这一杯酒?
“三驾马车”历史典故
汉代以前,军队中还没有现在所谓的骑兵,而是战车,就是两马拉一车的模式.中军统帅的战车和其他不同,是三匹马来拉,也叫“三驾马车”,是统帅的标志.这是帝王等级的待遇,所以“三驾马车”这个词也就有最好的,最豪华的意思在里面.

He is going to Shanghai this weekend.或者
He is leaving for Shanghai this weekend.
