不能一概而论,要分清从逻辑上你到底要表达什么意思。比如你说: , c' k- f% d1 A( b' j5 |7 I3 I
Don't drink and drive., s9 M3 y: t$ a5 _1 s2 I
: R) U5 @$ _. q. R3 K# I* l' M
I didn't hit and run. / d+ Q6 E+ f1 b9 k5 l6 V% x$ U' o6 a& F( l: m; G
要是把and换成or,那意思就又不对了。, f0 j; H, v3 W, T

3 p% i. u! I, L % C+ b$ o* j- q$ V. Q# |很多时候只是语言习惯问题。不知有没有常听这里的人说"i have no nothing" 意思是说我什么也没有。可用我们的逻辑否定的否定是肯定的话,意思正好相反。再来看看你的中文: 7 ?0 i# I' l8 k8 y. Q+ G' o" g+ i. c1 g+ D4 ^9 L6 M

你这话的意思是“学过计算机。。。。。。的朋友。。。。一写英文句子就犯糊涂”。难道不是很成问题吗?
