简单啊,最好的就是I want to improve my English,至于怎么improve嘛,自己组装一下吧.比如：read English magazines,
talk with foreighner,
watch English movies,Because I can watch the actor say the English.
Find a great way to learn English is the most improtant,so Iwill do it.
等等等,自己组装一下句子吧.还有其他的句子吗？额.....你心真大啊，好嘛，虽然我觉得已经50个词了。帮你加个结尾吧。I want to improve my English ,becabse I want to travel all over the world.When I go back,I will become a teacher,and teach my students how to improve English!就可以了，很简单滴，求赏分~~~~~我已经不用了，作业已经交上去了，不过还是谢谢你，赏分就给你了吧
