原文:Variables which are static and which are initialized only have their
initial value assigned once during the program’s execution. Thus, they can be
preferable over initialized auto objects which are assigned a value every time
the block in they are defined begins execution.
问题主要是在第二句，which are assigned a value every time the block in 感觉后面
不应该直接+they(这边的they我也不清楚是initialized auto abject还是 static
variables)
they are defined begins execution. 这边不是应该要+一个to吗?

少了which: the block (in which they are define)这个they 是指init. auto objects

谢谢，多一个which我就懂它的文法结构了
