SQLPlus中的復(fù)制和粘貼技巧

1. 用鼠標拖拽選取內(nèi)容

Improve Your Oral English NOW！

1．自己要有改變口語現(xiàn)狀的迫切要求，并開始行動。

2．要有一個方便的既能交流更能提高的語言環(huán)境。

3．持之以恒，細水長流，一步一個腳印。

4．學(xué)以致用，用了才能掌握。否則學(xué)了再多，浪費更多。

5．不要怕說錯。養(yǎng)成“舌頭先于大腦”的習(xí)慣，敢于說，敢于說錯，然后才能說對。

6．學(xué)會用最簡單的詞來表達。李陽說過：簡單重復(fù)，創(chuàng)造奇跡。

7．經(jīng)常練習(xí)英語表達，如問自己：“What is a table?” 然后試著用英語回答后，再去翻英英字典對照答案。每天堅持問自己幾個“ What is a…?”，獲益良多。

8．多看一些原版的DVD片，同時大聲模仿其中的對白。既練聽力，又練發(fā)音，還練語感，一石三鳥。
