参考答案:C解析:本题考查税法解释。立法解释是税收立法机关对所设立的税法的正式解释。税收的立法解释与被解释的税法具有同等法律效力。只有全国人大才具有立法权,因此C选项为正确答案。

If you do not use your arms or your legs for some time, they will become weak; and when you start using them again, they will slowly become strong again.       knows this, but nobody would think of     the fact.
Yet there are many people who        to know that the memory works in the same way. When someone says that       has a good memory, he       means that he keeps his memory in practice     exercising it very     , either consciously or unconsciously. When someone else says that his memory is     , he means that he does not give it enough      to become strong. The position is exactly the same as that of       people, one of      exercises his arms and legs by playing ball, while the other       in a chair or a car all day. If a friend of yours says that his arms are weak, we know that it is his own      , But if he tells us that he has a poor memory,      of us think that his parents are to blame, or that he is just     , and few of us realize that it is just as it was his arms or legs that were weak. Not all of us can become very strong in body or very clever in mind,       all of us can improve our strength and our memory by the same means that      .
Have you ever       that people who cannot read or write usually have      memories than those who can? Why is this? Of course, because they cannot write down something in a little notebook or something else. They have to remember names, places, songs and stories; so their memory is always being exercised.
In a word, if you want to have a good memory, do practice       things。
