Probably I shouldn't have said it's a two-step process 'cause it's a three-step process to actually write and run it, and the third step is just going to be to run it.

也许我不应该说它是个两步完成的程序,准确来讲，应该是三步，前两步--写，第三步--运行。

Last year for the pieces that do vary year to year a bit, last year's first problem set challenged students to write their first or maybe second or third program using this environment called Scratch.

去年的教材有些地方有略微改动，去年的第一个问题集是让学生,在Scratch环境下,写下自己的第一或第二个或第三个程序。
