翻译英语

让我来帮助你吧，首先看到这十个题目就会发现这是在考察英语的事态，主要涉及现在时，过去式，以及完成时。只要区分好其区别，我会随后附上翻译解析，帮助你更好的理解，那么解决这些题目就游刃有余了。那么我们现在就开始翻译吧！

①她每个月买一件衣服。She buys a piece of clothes every month.(这句话强调的是经常性的习惯动作，所以采用一般现在时)

②他正在买一辆车。She is buying a car right now,(正在表示现在时)

③我想要成为一个医生。I want to be a doctor(既然是想那肯定是还没成为呢，对吧，所以是对自己将来的期待，我们用一般将来时)

④我在三年前想成为一个老板。I wanted to be a boss three years ago。或者I aspired to become a boss three years ago.(这句话我想要解释一下，三年前是一个过去的状态，所以用了过去式，而为什么用了ago没有用before呢，很简单ago表示过去式，而before表示完成时，而这句只强调了一个过去的状态或要求)

⑤他们正在电脑房里下棋。They are playing chess in the computer room.或者They are playing chess in the net bar.(正在表示进行时。而我觉得net bar更为口语一点，就看楼主的喜好了，两者皆可)

⑥昨天他已经弹过钢琴了。He had already played the piano yesterday.(这句话要注意的是乐器前面加the.而球类和棋类不加冠词，比如play basketball)

⑦他们三小时前在教室里。They were in the classroom three hours ago.(三小时前是一个明显是过去表现所以要用过去式were)

⑧我不喜欢教Z（Z是人名）Actually,I do not like to teach Z.或者说，I do not want to be the teacher of Z(这句话用了翻译技巧中的词类转化，完全可以，使句子更加灵活，而我不喜欢这句话是说我的特性，是一个惯常的行为，所以要用一般现在时)

⑨太阳在东边升起。The sun rises from the east(这句话考查的是真理要用一般现在时，比如，太阳围绕地球转啊，三角形内角和为180度啊~等等这些恒常不变的定理规律都要用一般现在时)

⑩警察昨天抓了一个小偷。A policeman caught a thef yesterday.或者A thef was caught by a policeman.(我要强调的是这个定冠词the 是不能随便用的，我看了别人的回答，怎么能用the呢这句话只是说一个警察，而不是说就是那个警察，对吧，所以一定要用a表示泛指，表明这个小偷是警察抓的而不是工人或者职员等等)。

恩，好，翻译完了，觉得还可以吧！
知其然还要知其所以然，授人以渔不如授人以渔，研究语法已经很多年了，楼主能给出这样的分数，肯定有其用意，所以我也花了些心思揣摩之后形成我的译文，希望能够对楼主有所帮助！
