有没有值得推荐的新概念英语2的英语老师
新东方李延隆老师，有钱买正版课程，没钱去哔哩哔哩自己搜。新概念的3.4册有两个老师的版本，个人比较喜欢李延隆，讲解清晰，老师的普通话也说得很好，另外一个老师讲得稍微简单一点，自学还是看李延隆的吧。如果资金不足的话，有个app，好像就叫新概念英语，iosappstore可下载，里面有北大的老师讲解的视频，觉得还不错，就是年代有点久远了，画质不好，但是内容差不多的。新概念是世界经典，修订只是改了一下通货膨胀，内容基本没变，可以听的。有小伙伴说爱奇艺可以买，我记得曾经在爱奇艺里看到过，有会员的可以去看一看.
PR教程
AdobePremiere是Adobe家族的一款剪辑软件，它给我的感觉就是入门快、功能强大，无论是对于新手还是专业人士，PR在大部分情况下都是很友好的。
认识PR
Pr全称AdobePremiere，是Adobe公司开发的一款视频剪辑&编辑软件。主要用于视频采集、视频剪辑、调色、添加字幕、编辑音频、渲染输出。
Premiere提供了采集、剪辑、调色、美化音频、字幕添加、输出、DVD刻录的一整套流程，并和其他Adobe软件高效集成，使用户足以完成在编辑、制作、工作流上遇到的所有挑战，满足用户创建高质量作品的要求。
下载PR软件
Adobe官网下载
进入Adobe官网进行下载https://www.adobe.com/cn/products/premiere.html
其他网页下载
1、打开浏览器今日头条搜索3D溜溜网，进入官网
2、打开浏览器百度搜索3D溜溜网，进入官网，点击上面【···】三个点之后选择【软件插件】里的【羽兔网软件下载】
3、选择【常用软件】里的【视频制作】
4、向下滑，在下面找到PR2018版本的进行【软件下载】，里面还有其他版本，这里选择的是适配win7的。
PR窗口介绍
Premiere软件由菜单栏、常用工具栏、时间轴、侧边面板栏（组件窗口）组成。主工作区有素材（项目）管理窗口、素材预览窗口、视频监视器窗口、时间轴窗口、调音台窗口、调色窗口等。
菜单栏
菜单栏可以说是整个软件的功能导图，为软件中大多数功能提供了菜单入口，例如PR软件中的绝大多数功能在对应的菜单栏中都可以找到。
功能窗口切换区域:(组件、编辑、颜色、效果、音频、字幕、库......)
功能窗口切换区域是软件为剪辑、调色、音频、字幕等不同功能定义的界面布局方案。点击对应的功能，软件会自动切换到使用该功能时的界面布局。
源素材预览窗口
源窗口主要是为项目面板中素材(视频、音频、图片)提供实时预览，双击项目面板中的素材即可在源窗口中进行播放预览。
节目监视窗口
节目窗口主要用于监视时间线上剪辑的画面，可以实时播放。
项目面板
项目面板主要是用于项目及素材的管理，我们导入到软件中的素材及新建的序列、字幕等素材全部都存放在项目面板中。
时间线窗口
时间线窗口可以简单理解为剪辑工作台，我们对素材的剪辑工作全部都是在时间线面板中操作完成。时间线窗口又可分为视频轨道和音频轨道。
工具栏
工具栏集合了所有视频剪辑工具，当然有一些是辅助剪辑工具。
选择工具（快捷键：V）
顾名思义，它的作用就是用来选择东西的，不过在有的时候它也会变为其它的形状，作用也随之改变。
向前选择轨道工具（快捷键：A）
使用此工具可以选择该轨道上以后的所有素材，视音频链接在一起的则音频同时也被选中；按住Shift键可以变为多轨道选择工具，此时单头变为双头，即使是单独的声音（比如音效、音乐等）也会被同时选中。
波纹编辑工具（快捷键：B）
使用此工具可以改变一段素材的入点和出点，这段素材后面的会自动吸附上去，总长度发生改变。
剃刀工具（快捷键：C）
pr中导入素材之后，利用剃刀工具切割开视频，视频就分开为多段了，可以分别剪辑切割后的每一段视频，包括删除、添加效果等。
外滑工具（快捷键：U）
作用于一段素材，用来同时改变此段素材的入点和出点。
钢笔工具（快捷键：P）
这个工具和字幕中的钢笔工具是一样，主要用来绘制形状。选中此工具，在需要的位置点击一下确定起点，直接点其它位置可以绘制直线，而在点第二个点的同时按住鼠标不放并进行拖拽可以绘制曲线；它还有一个作用就是进行关键帧的选择。
手形工具（快捷键：H）
点击鼠标左键，在时间轴上拖动，移动时间轴上显示素材的位置。当程序监视器放大时。拖放程序监视器中的可移动显示区域以观察细节。
文字工具（快捷键：T）
文字工具即在画面中输入我们想要的文字。
效果面板
效果面板集合了很多视频和音频效果控件，对视频或者音频添加模糊及转场等效果时，需要在效果面板中找到对应的效果控件然后添加到时间线上的剪辑。
效果控件面板
效果控件面板是对已经添加到素材上的效果进行参数调节的窗口。
音轨混合器窗口
对音频进行声道和音量调节的窗口，当然也可以通过这个窗口进行现场录音。
PR剪辑教程
创建项目
首先新建项目，暂存盘里的地址栏跟项目一样就可以。
新建序列
新建序列，选择1080p25，点击确定，就建立了一个时间线。
一般的剪辑软件里边都有现成的预设，只要知道这个尺寸就行，高清格式选择1080P或者720P都行。
导入素材
在项目列表双击，找到我们的素材，按住shift一块儿导入，导入之后可以对素材进行分类，让我们可以看的更仔细一些。（养成一个好的分类习惯，有助于提高我们工程的有趣性和效率，以后打包工程的整理都非常的有好处）。
拖入时间线
素材分类好之后，把视频音频素材按住shift一起都拖拽到时间线里。
设置比例
发现视频素材的大小不一，我们调整视频整体比例大小。找到信息，看见比例为640*360，在我们新建的时候不是这个比例，我们在序列里进行更改设置为640*360，这样时间线就跟我们相匹配了。
编辑视频
导入素材之后，我们开始对视频进行剪辑。
添加效果
添加效果，让视频看起来更流畅。
添加字幕
添加结尾字幕。
导出
剪辑完成，导出成品。
PR导出格式一般用MOV、mp4、AVI等等。PR输出视频的时候，要求不一样，输出的格式的就不一样。因为没有统一的标准，要根据需求和目的才能定什么是合适的。
1、如果想输出文件后继续进行编辑，一般推荐输出MOV。
2、如果输出文件后直接就要观看，或传到视频网站。推荐输出H.264，即mp4。
3、如果输出文件给电视台标清播出，就输出AVI格式。
成品
下面这张是成品
这里用的是PR2018版本
PR基础快捷键
1、按i可以设置入点，O可以设置出点。
2、Shift+delete键可以删除视频同时，把视频之间的间隙去掉；Ctrl+Z撤销。
3、向前选择轨道工具（A）和链接选择项的结合使用可以删除选择点后面的视频和音频
4、向前选择轨道工具（A）和取消链接选择项的结合使用按shift键可单独删除视频，保留音频。
5、按Q键可删除剪辑的开始，按W键可删除剪辑的结尾，但是它们会从每个音轨中删除内容，如果有多层音轨，这个快捷键就不适用，可以通过锁定音频轨道来避免音频被删除。
6、按光标键→，按一下前进一帧，按Shift键+光标键，一下会前进5帧。
7、alt+拖动素材=复制
常用的快捷键如下：
注：如果自己不适应默认的快捷键可以在PR界面快捷键设置修改，步骤如下：
打开快捷键界面有两种方法：第一种方法，打开PR后，在菜单栏找到编辑选项下的快捷键菜单，单击后就会弹出设置界面。第二种方法，打开PR后，我们直接使用快捷键Ctrl+Alt+K后，也会弹出设置界面。
打开快捷键界面后在搜索框里我们直接输入想要添加的快捷键功能，然后在空白处单击鼠标，就会产生一个框，按下要设置的快捷键，最后点击确定保存设置，这样就快捷键就设置好了。
PR视频特效
添加滤镜
首先就是滤镜的位置是在左下角的【效果】选项里面，如下图箭头指向所示：
里面的滤镜很多，可以选择自己喜欢的滤镜进行使用，如下图箭头指向所示：
然后，我们直接将滤镜拖拽到素材身上就可以进行使用了，如下图箭头指向所示：
调整滤镜的内部可调节参数，素材的效果就能实时预览。点击前面的【FX】可以进行滤镜效果的开启以及关闭，如下图箭头指向所示：
效果里面，除了视频滤镜，还有音频滤镜以及各种转场可用，如下图箭头指向所示：
添加字幕
在工具栏，点击文字工具；
使用文字工具点击视频，在文字框中输入字幕，就添加字幕成功了。
视频的删减
导入完素材之后我们将素材拖到右边，便能对视频素材进行编辑了（点击播放按钮可预览）。接下来我们讲一下视频内容的删减。
比如说：我们觉得某一段内容不好，想把它删掉，那么该怎么办呢？在PR中我们有两种方法：
1、选择左侧工具栏的刻刀工具，在想要删去内容的两头进行点击，然后即可将商品分割成三段，可从中选择自己不想要的内容；
2、直接从末尾拖动即可（只能对开头或末尾内容进行删减）。
视频的倍速播放
视频的倍速播放在PR中很容易就能实现了：右键-速度/持续时间。选择速度（百分比，如200%就是两倍速），点击【倒放速度】就能倒放了。
音乐淡出效果
添加音乐的方法和添加视频的方法一样，导入以后拖动到右边就可以了。删减运用上述方法也是可以完成的。
音乐淡出的效果：
添加完音频后，拉开轨道，点击左下的小按钮，选择：轨道关键帧-音量；
选择：添加-移除关键帧按钮，在想要淡入、淡出的地方添加关键帧，即可对音量进行修改，完成淡入、淡出的效果；
如果你是第一次使用PR并且佩戴耳机的话，要到PR的【编辑】-【首选项】-【音频硬件】里的【默认输出】修改输出设备为：耳机。
音效增益
打开PR软件，将音频导入进去，拖到右下方的【时间轴】操作区；
右击鼠标，点击音轨，在出现的选项中点击【音频增益】；
在【音频增益】页面，选择【将增益设置为】；
输入合适的音频值，负数表示减少，完成后点击【确定】。
视频转场
首先打开电脑上的PR，打开项目文件后，选择右侧的【效果】面板，效果面板中有音频效果、音频过渡，视频效果、视频过渡；
鼠标点开【视频过渡】，其中有7类转场特效，我们这里点击进入【溶解】，选择【溶解】下的【交叉溶解】；
选择【交叉溶解】拖动到视频上，可以看到我们可以将转场放置到视频末尾，视频开头或两段视频中间，这里选择【视频中间】；
插入完成后我们双击此转场，进入【设置过渡持续时间】，拖动蓝色字体即可增加或减少时间。
