What are you doing here？ 是最常见的、中性的、比较正宗的询问方式，不像汉语里，如果想用这句话表达反感、不欢迎等态度只需加重语气即可，英语如果想表达不耐烦、不欢迎、惊讶等情感，最好加上上下语境。

8.

14.
"Have you been here before?"" Yes, I have.""When was is?""It was in 1996."
“你来过这儿吗？”“来过。”“什么时候来的？”“1996年来的。”
15.

2.我这句话这样用英文表达正确吗不能说 people who without friends~
the truth 而不说 this truth
~
参考：
这个世界上有一种人，没有朋友..也没有爱..而我就是这种人的一半..这个事实永远都不会变..或者这就是我的命运"
there is a group of people, who have no friends nor love, and I am part of the group. the truth will never be changed, but this might be my fate.
3.这句话用英语怎么说上面的回答有点生硬，似乎是在翻译软件里面的
我觉得可以这样翻译
i want to earn money from foreingners in foreingn countries to do something for motherland ,other than (instead of)seeing the foreingers flow into china and earn money back.
嗯。
i want to make(earn两个都可以啊) money for the country from abroad,not foreigners earn money in china
make money是一个固定搭配 意思就是赚钱，挣钱。
如果是要表达赚很多钱，可以说make much money
明白吗？
4.这句话用英语怎么说呢I don't really like the job which already has a certain direction.For example, math. Cause this kind of major feels like put me in a circle, and force me stuck in ot; it gives me a feeling of uncomfortable. I may feel like I'm living in the jail if I lean or do such job. And I feel that kind of career is limiting my work energetically.
My dream career should give me the unlimit vision, cause this kind of job doesn't give any certain direction. Just like graphic design or speech, I would never feel tired to do that kind of job. I would rather get less pay, or no call-back pay, and I could even take it back home and keep my passion on it. Please give me some advances about the major which fit for me.
不要用kinda 去代替 kind of，不要有hate 和 piss off. 太口语话。我将hell改成jail是不教委婉，太不委婉给别人感觉不太好。我将certain answer改成certain direction 是觉得answer太笼统，certain direction明确的方向我觉得更能体现你的想法。我也不是改的完全没有错误，不过觉得稍微比开始的好点。我是美国大学的学生，语法不能保证。毕竟是你的想法，别人只是理解很难帮你达到充分的表达。还需要自己多加修改。对话最重要的是自己想到什么说什么，事前准备再充分也会出错。只要敢说就好了，他们会明白的。
5.这句话英文怎么表达好呢另外，这两款产品的开模费用需要$400， 但工厂承诺，当每款订单量超过1000套的时候，样品费用会返还给你。
In addition, you have to pay $400 modelling fees for these two products, but the factory has promised that your sample fees will be refunded when the order is more than 1000 units. 替你翻译好了。【很希望我的回答会对你有帮助。
