可可网友们大家好。今天我们来学习几个用and连接的习惯用语。它们帮助我们描述了一台十一岁高龄的老轿车至今兢兢业业服务于人，而车主也是对它情有独钟的一小段文字。

It's true that my car looks old and worn out. It's eleven years old, and it has a lot of wear and tear on it. But I'm tired of my friends telling me to get a new car. By and large, my car still runs okay. It takes me where I want to go. I use it to go back and forth to work every day, and it doesn't break down very often.
When it does break down, I take it to my mechanics. They know the ins and outs of my car. They don't give me a song and dance. They tell me exactly what's wrong with the car and how much it will cost to fix it.

一台十一岁高龄的车就算保持的再好也会有很多的wear and tear在上面。但是，by and large，it runs okay. 我们首先来看Wear and tear, 磨损的意思。再比如：Apart from fair wear and tear, the car is in excellent condition. 这辆车除了正常磨损外，一切完好。虽然有磨损，但是by and large，大体上看，总的来说，还是不错的。我们来看一个例子：Before liberation there was no heavy industry in China by and large. 大体上说，解放前中国没有重工业。

这台老车每天带着我go back and forth to work. 回来，再过去，也就是往返于工作地点和家之间。即便车出了问题，我把它送到熟悉的机械师那里，他们对我的车的ins and outs了如指掌。Ins and outs, 里里外外都知道，也就是所有的复杂细节都了解。再比如：After careful investigation, he got to know the ins and outs of the accident. 经过仔细的调查，他了解了事故的来龙去脉。

让这样熟悉我也熟悉我车的机械师帮忙修车，就不用担心挨宰，不用担心他们光会说a song and dance 花言巧语了。非常有趣的的一个习语。我们再来看几个例子。Don't give me a song and dance. Tell me what you want. 不要跟我废话，告诉我你想要什么吧。She gave her parents a song and dance about having to use their car. 她花言巧语地骗她父母为什么必须用他们的车。

其实，英语中用and连接的习惯用语很多，再比如safe and sound, fair and square等等。好了，来听今天的问题：When you know the ins and outs of something, do you know it well? 我们下期再见吧。
