我問我點可以怏d講英文

難聽o的講句你連中文都有語病所以英文亦一定唔會好.
(咩叫做 "快o的講英文?" 應該叫講英文可以講快o的? 或者流利一o的?)
我讀大學時英文堂個講師講得好:
"要英文流利, 先要知道自己要講o的咩"
即係話, 除左必要既英文能力之外,
先要冷靜想一下自己要講o的咩,
整理好之後就可以慢慢有條理咁將自己既想法講出黎.
越急就講得越差, 反而慢慢黎會好少少.
得個快字但係冇grammer冇organization等如冇講過.
所以咯喎, 先唔好緊張, 慢慢將自己既想法整理好,
再講出黎. 亦唔使怕人地笑你講野慢, 你慢人地唔知你講乜仲好啦
(我有時都講唔出我想講既野)
當然如果你既英文本身都唔得既話就要去上堂.
祝你好運勒~

talk everyday

睇多d 英文台, 由要睇字幕去到唔洗睇, 留意佢哋發音, 語調, 用詞
英文係一種溝通方法, 最緊要係溝通到同人哋明你意思, 只要你唔怕醜, 勇放去講同表達, 好多人唔會笑你, 會敎你 (但當然你要有比人笑0既心理準備, 我以前都比人笑唔少), 但你放心, 笑完通常都會敎你, d 外國人其實絕大部分都好nice, 你會喺佢哋身上除咗學會語言之外, 仲會令自己0既思想同視野擴大, 所以你要積極d 用你0既方法去密識一d 外國人千祈唔會淨係識群中國人, 咁只會令你自己中文同英文都無進步, 一種語言唔係單單喺本書或上堂去學, 係要喺生活中不斷運用而熟能生巧, 因為喺生活中你會學到一d 喺書到學唔到0既嘢, 例如講法, 聲調, 俗語等
我自己喺外國十年, 十一歲去咗留學, 喺一年之內已經學到一口流利英文, 你幾大個?? 因為學習同年齡有好大0既關係.

You may go to some non profitable community hall to see whether they can provide some kind of orientation course for the new immigrants. As I had been to Wisconsin before and they will provide some course for the people that they want to learn more English in order to have a much faster way to get into the community. The teachers are all voluntary and probably they are retired people.
good luck in USA.
