01:28查看AI文稿AI文稿高考全国假卷和乙卷的区别？呃，全国假卷和乙卷的区别呢？呃，有几个方面的不同。第一个呢，适用的地区不同，全国的假卷呢，适用于西藏、四川、贵州、广西和云南。 以卷呢，适用于甘肃、青海、内蒙、黑龙江、吉林、宁夏、新疆、陕西、河南、山西、山东和安徽这几个省份。第二个不同的是难度不同，全国的以卷呢，相比假卷呢，更难一些啊。全国的假卷呢，对应的是新课标的三卷，全国以卷对应的是新课标的二卷，新课标一卷。 那以卷的英语和物理的科目呢，能够很明显的看出来要比假卷难。不过呢，一些考生呢，会觉得假卷更难，这是根据学生的大体的程度去判断的。不过呢，甲乙卷呢，都会在高考当中去使用。第三个方面是不同的是科目不同。全国的甲乙卷里面的科目呢？呃，也有不同 的地方。首先呢，全国的语卷科目三家，文科综合和理科综合三家，文科综合，理科综合模式呢，各考六科四种试卷啊，既报考文科的学生考语数英和文科综合，那么报考理工科的学生呢，语数英加理科综合。 全国假卷科目啊三家，文科综合和理科综合三家，文科理科综合模式呢，各考六科四种试卷啊，即报考文科的这个学生考那语数英语文英语数学和文科综合。 报考理理工科呢，就是英语，呃，就是英语、数学、语文和理工增呃，理工的科目。如果还不清楚，家长啊，可以评论区互动。

01:51查看AI文稿AI文稿今天我们开始二零二四全国以卷理科的讲解，二零二三全国以卷适用御干陕、宁干清、新蒙这些省份。当然今年呢，还会有所变化。我们看第一题是考察复数， 复数 z 等于这样一个分式，注意到分母上有这样三项相加，我们知道 i 的平方是等于负一的， 那么 i 的四次方就等于 i 平方的平方，也就是正义。所以 i 的五次方呢，就是 i 的四次方，再乘以 i， 那就等于 i， 于是他要求的这个负数 z 等于二加 i 除以一减一加 i， 那就 就是二加 i 除以 i。 复数的除法，我们往往是上下同乘以分母的共额复数。分母现在是个 i， 它的共额复数就是复 i， 所以上下同乘以父爱，那么分母就变成了父爱方，上面是父爱，乘以二加爱。由于爱方呢，等于负一，所以父爱方就是一。 上面等于负二， i 再减去 i 方，这里呢，负 i 方又是一， 所以整个就是一减二挨。而这里注意他要求的不是复数 z， 是 z 的共厄，上面有一个杠，要注意看清，共厄复数就是跟原来的这个复数 十不相同，虚不互为相反数。所以呢， z 的共厄等于一加二， i 应该选择 b 项。

02:31查看AI文稿AI文稿都说今年的全国乙卷难，咱们来看一道天空压轴题，看看它难度到底如何。这 a 属于零到一，若这个函数在零到正无穷上单调递增，求 a 的取值范围。看到函数的单调性，我们应该想到利用求导的方式解决单调性， 所以咱们先对函数求导， f 撇 x 等于 a 的 x 次方乘以烂以 a 加上 一加 a 的 x 次方乘以烂音一加 a。 要想让原函数在零到正无穷上横增， 只需要导函数在零到正无穷上横大于等于零，所以我们要研究 f 撇这个函数的最小值，只需要最小值大于等于零即可。那么要想研究导数的最小值， 我们需要知道这个倒数的单调性，那么这个倒数的单调性该如何去研究？我们先把 x 的部分合在一起，两边同时除以一加 a 的 x 次方，因为一加 a 的 x 次方永远是一个正数，所以这个不等号的方向是不需要改变的， 变完之后就变成了 a 比上一加 a 的 x 次方乘以滥引 a， 再加上滥引，一加 a 大于等于零，我们不妨把它设成一个新函数 j x 来看。这个函数 a 比上一加 a 是在零到一之间的一个数， 零到一之间的一个数作为底数，对应的指数函数就是一个单调递减的函数乘以烂以 a。 注意， a 是在零到一之间，所以烂以 a 是一， 一个负数，单调递减的函数乘以一个负数，就是单调递增。所以 j x 单调性咱们就知道了，是一个增函数，那么 j x 就应该大于 j 零， 而 j x 又要大于等于零，所以只需要让 j 零大于等于零即可把零带入这一部分是一，所以就得到了烂音 a 加上烂音 一加 a 大于等于零，整理一下变成烂印。 a 方加 a 大于等于零，也就是 a 方加 a 大于等于一解这个不等式，最后就得到了 a 大于等于二分之根号五减一小于一。全国以卷的天空压轴体难度到底如何自己来评判。
