be used to doing和used to do的区别

例句：I used to cut fruit with the knife which is used to cut meat, so now I am used to eating fruit with the flavor of meat.

直译：我过去常常用切肉的刀来切水果，所以现在我习惯于吃带肉味的水果了解析：1.used to do sth.表示“过去常常做某事”变否定句既可以在used的前方加didn't，也可以在used后方加not.

I used to be short, but now I am tall.

我过去很矮，但是现在很高。

He used to be afraid of dark, didn't he? / usedn't he?

他过去很怕黑，不是吗？

be used to do sth.表示“被用来做某事”，这是一个完整的被动语态形式。to do可以用介词for来替换，be used for sth.

Knives are used to cut fruit.

刀用来切水果。

Knives are used for cutting.

刀用来切东西。

be used to doing sth.表示“习惯于做某事”，此处的to是一个介词，介词后一律加动词的ing形式。

I am used to walking along the river after dinner.

我习惯于饭后沿着河边走一走。

PS：常见的to是介词的短语。

be accustomed to doing

devote oneself to doing

look forward to doing

pay attention to doing

prefer doing to doing。

循环字符串的每一个字符，判断是否为汉字，是的话占长度2,否则占长度1

取：left(str,长度)

这样你总会了吧

if abs(asc(whichChar))>127 then

Response.write whichChar & "是一个汉字"

else

Response.write whichChar & "不是一个汉字"

end if
