因為他很聰明，所以他的成績總是很高。
Incorrect English：
“Because he is smart ，so his grades are always very high。”
Correct English：
“Because he is smart ，his grades are always very high?！監(jiān)R“He is smart ，so his grades are always very high。”
解釋：
這個問題與“問題3”非常類似。這種類型的句子，我們可以用“because”或“so”，但兩者不能同時出在一個句子里，其中之一既可表達(dá)“因為。。。。。。所以。。。。。?！钡囊馑?。在表達(dá)“因果關(guān)系”的句子里，用“because”的句子與用“so”的句子并沒有明顯的區(qū)別。
Explanation：
This problem is very similar to the problem in number 3。In a sentence of this kind，we can use “because”or “so”。We cannot use both words，as this is incorrect。One word is enough to convey the meaning . There is no real difference between the sentence with “because”and the sentence with “so”。
Examples：
“Because the tea is too hot，he doesn’t want to drink it。”O(jiān)R“The tea is too hot，so he doesn’t want to drink it?！?BR> “Because the Chinese economy is developing quickly，we can see rapid changes in China?！監(jiān)R “The Chinese economy is developing quickly，so we can see rapid changes in China?！?BR> 注意：
在英語中有另外一種很自然的方式表達(dá)上述類型的句子，即先說結(jié)果，再用“because”引出原因。
Note：
There is another very natural way to express this kind of sentence in English。We put the result first，insert the word “because”，and then put the reason last。
Examples：
“His grades are always very high because he is smart?！?BR> “He doesn’t want to drink the tea because it is too hot”。
“We can see rapid changes in China because the Chinese economy is developing quickly?！?
Incorrect English：

“Because he is smart ，his grades are always very high?！監(jiān)R“He is smart ，so his grades are always very high。”
