英语外教一对一的费用与什么因素有关系？

　　英语外教的教学模式是很多家长的选择，但英语外教一对一的费用并不是固定的，那么英语外教一对一的费用与什么因素有关系?

　　The teaching mode of English foreign teachers is the choice of many parents, but the one-to-one cost of English foreign teachers is not fixed. What factors are related to the one-to-one cost of English foreign teachers?

　　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 also choose twoorthree classes together.

　　2、上课方式

　　2. Class method

　　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 types of mainstream classes, online and offline. Online is to take classes through the Internet. You can prepare class materials within the specified time and listen to the teacher. Offline classes may be in institutions or at home. You can choose according to your own wishes. Online and offline teaching have their own advantages and disadvantages, which can be selected according to 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。大嘴外教建议您可以到机构去试听看看，或者实在不知道怎样选择的可以听听顾问老师的建议。

　　This covers a wide range, such as whether the 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 not, and which school they graduated from, etc. Big mouth foreign teachers suggest that you can go to the institution to have a try, or if you really don't know how to choose, you can listen to the advice of the consultant teacher.

　　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 promotional courses, and so on.
