中国改革开放的第一个突破口是

A．农村实行的家庭承包经营

B．乡镇企业的异军突起

C．兴办经济特区

D．十一届三中全会确立实事求是的思想路线

答案

参考答案：A

解析： 中国改革首先在农村取得突破，所以“第一个”突破口是农村的家庭承包经营；兴办特区是继农村改革之后的“另一个突破口”，乡镇企业被称为农村改革的“意外收获”，实事求是的思想路线是整个“新时期”的前提、基础和历史转折点，不只是“突破口”的意义。

单项选择题

Why is（）fun What delights may its practitioner expect as his reward First is the sheer joy of making things. As the child delights in his mud pie, so the adult enjoys building things, especially things of his own design. Second is the pleasure of making things that are useful to other people. Third is the fascination of fashioning complex puzzle-like objects of interlocking moving parts and watching them work in subtle cycles, playing out the consequences of principles built in from the beginning. Fourth is the joy of always learning, which springs from the（）nature of the task. In one way or another the problem is ever new, and its solver learns something: sometimes （）, sometimes theoretical, and sometimes both. Finally, there is the delight of working in such a tractable medium. The（）, like the poet, works only slightly removed from pure thought-stuff. Few media of creation are so flexible, so easy to polish and rework, so readily capable of realizing grand conceptual structures. Yet the program（）, unlike the poet’s words, is real in the sense that it moves and works, producing visible outputs separate from the construct itself. It prints results, draws pictures, produces sounds, moves arms. Programming then is fun because it gratifies creative longings built deep within us and delights sensibilities we have in common with all men.

Fourth is the joy of always learning, which springs from the（）nature of the task.

A．repeating

B．basic

C．non-repeating

D．advance
