英语外教一对一的费用和什么因素有关系？

　　不少人选择英语外教一对一的教学形式，但是不了解费用，今天来跟大家讲讲英语外教一对一的费用和什么因素有关系?

　　Many people choose the one-to-one teaching form of English foreign teachers, but they don't understand the cost. Today, let's talk about the relationship between the one-to-one cost of English foreign teachers and what factors?

　　1、上课时长

　　1. Class duration

　　上课时长是跟费用息息相关的，一般来说，上课时间越长费用就越高。不同的机构课程时长是不一样的，从30分钟-90分钟不等，时间短的话还可以选择两三个课时一起上。

　　The length of class is closely related to the cost. Generally speaking, the longer the class time, the higher the cost. The duration of courses in different institutions is different, ranging from 30 minutes to 90 minutes. If the time is short, you can choose two or three classes together.

　　2、上课方式

　　2. Class mode

　　现在的主流上课方式主要有两种，分为线上和线下。线上就是通过网络上课，可以在规定的时间内准备好上课资料，听老师讲课就行。线下有可能是去机构上课，也有可能是到家里来上课，可以根据自己的意愿选择。线上和线下教学各有优缺点，可以结合自己的实际情况选择。

　　There are two main ways to attend classes, online and offline. Online class is through the network. You can prepare class materials within the specified time and listen to the teacher. Offline may be to attend classes in institutions or at home. You can choose according to your wishes. Online and offline teaching have their own advantages and disadvantages, which can be selected in combination with their own actual situation.

　　3、外教老师

　　3. Foreign teachers

　　这个包括的范围就广了，比如外教老师是全职还是兼职，是国语国家外教还是非母语国家外教，是有经验还是没经验，是哪一所学校毕业的等等。

　　This covers a wide range, such as whether foreign teachers are full-time or part-time, whether they are foreign teachers from Mandarin speaking countries or non-native speaking countries, whether they have experience or no experience, which school they graduated from, etc.

　　4、课时长短

　　4. Length of class hours

　　报名36课时的跟报名98课时的肯定不是一个价格，费用也不仅仅是简单的叠加，很多机构都有优惠课时，一般是报名课时比较长的话会有优惠，或者说连报，报名促销课程等等。

　　Registering for 36 class hours is certainly not the same price as registering for 98 class hours, and the cost is not just a simple superposition. Many institutions have preferential class hours. Generally, if the registration class hours are long, there will be a discount, or even apply, sign up for promotion courses, etc.
