我高中时数学也很差,也请过家教,可是还是不能从根本上提高能力,你可以找你的数学老师帮你补课,我高中时曾到一个挺有经验的老师那补过课,她就不断给我做练习卷,当时正好在学向量,我就去了几次吧,向量单元考出的成绩确实证明了自己只要努力就会有回报,可惜的是后来这老师生病不教学生了,我的数学成绩又变差了.平时多做卷子,比较差的题型多练习,不要怕麻烦,多做做就会有感觉了,千万不要懒,多花点精力肯定会有效果的!

动宾结构是语法里的知识
短语根据成分的不同分好多结构,就拿你说的动宾结构为例吧
动,指的是动词,比如吃,提出,打扫等都是动词
宾,指的是宾语,在一个短语或者一句话里,跟在动词或者形容词后边的成分叫宾语,宾语通常有名词或者形容词充当.比如高,米饭,意见,伟大,雄伟等等.
那动宾结构就是这两个成分组在一起的短语或者句子就是动宾结构.比如吃米饭,提出意见,打扫教室,等等好多.
明白了吗?
下面我给你出几个,你判断一下:

Hi there,how are you?I was busy working recently,didn't reply much to you as I felt tired.But anyway today is your birthday so HAPPY BDAY!you throw any good fun party today?

不知道什么时候,摩天轮成了幸福的代表,一个个如我一样的孩子,就在夕阳中仰望那代表幸福的摩天轮,在心中憧憬幸福的模样,一遍一遍,不知疲倦,只是向往.
　　时间像流水一般划过,夜,月光加带着现实的迷茫,触及心脏的尖端,零星但真切的疼痛,一阵一阵,一点一点,吞噬着我的幻想,恐慌不知所以.可还是固执的相信一切,于是,幸福而忧伤的自欺欺人.
　　终于,我受伤了,泪眼迷蒙中,再一次想起了,摩天轮.带着疑惑,带着伤心,我来到摩天轮脚下.
　　仔细端详着摩天轮真实的模样.
　　岁月在塔身上留下斑斑锈迹,在夜色里,斑驳诡异,抚摸塔身,粗糙且冰凉的质感……
　　摩天轮的映像在我心中轰然倒塌.
　　原来,所谓的幸福是如此的沧桑,我明白了,不怪摩天轮,是我自己太傻,心甘情愿把理想寄托在虚幻之上,现在终于明白,现实残酷,生活就是生活,没有那么多的幻想.
　　于是,懂了.
　　于是,不再仰望.
　　于是,脚踏实地.
　　向远方走去,心中默念：
　　再见,摩天轮.

证明:延长AE交BC的延长线于F,
在△BCD和△ACF中
∠BCD=∠ACF=90,
BC=AC
∠CBD=∠CAF,
所以△BCD≌△ACF(ASA)
∴BD=AF
又2AE=BD,
∴AE=EF
又AE垂直于BD的延长线于E
所以BE垂直平分AF,
∴BD平分∠ABC

这句话写错了一些地方哟!应当是：I like a quiet reading after supper.
主语：I
谓语：like
宾语：a quiet reading
after supper是时间状语,修饰动词like.
不明白的再问哟,请及时采纳,多谢!

你的地址有问题哦,按照英文直接翻译是：
新界元朗沙田米埔陇村58号邮箱34
但地址中的又有沙田又有元朗,明显是不对,因为沙田和元朗属于两个不同地区.

新界元朗米埔陇村58号邮箱34
楼上的很奇怪.
