例句與造句

1. Regular local variables in source code are defined within a block , which may be the entire method body or some nested block
   源代碼中一般的本地變量都定義在一個(gè)塊中，這個(gè)塊可能是一個(gè)完整的方法體或者是一個(gè)嵌套塊。
2. A local variable , already declared in an enclosing block and therefore visible in a nested block , cannot be redeclared in the nested block
   一個(gè)語句塊里的變量，可以被其他語句塊再次聲明，但是不可以在嵌套語句塊聲明，但是在嵌套塊里他是可視的。
3. It's difficult to find nested blocks in a sentence. 用nested blocks造句挺難的
