sew on a button meaning in Chinese
缀纽扣
Examples
- I had no idea if she could even sew on a button
我甚至不知道她会不会缝扣子。 - I had no idea if she could even sew on a button
我甚至不清楚她是否能缝上一个钮扣。 - Taking this analogy a little further , if one needle had to sew on a button ( blocking i / o ) , the other needle could continue doing other useful work even if the other needle took 4 hours to sew on a single button
把这个比方再扩展一下，如果一颗针要缝一个钮扣（ i / o阻塞） ，即使这项工作要耗去4小时，另外一颗针也能同时做别的有用的工作。
