67. 一张纸fold 以后，求sheet of paper fold的面积（图跟不上，和狗狗的题号一样）
1. BC=18; 2. BE=13
107. 小明去度假，一共有11天是下雨的，一般呢要是上午下雨下午就不下，反之亦然。在度假期间有18天上午是没下雨的有20天下午是没下雨的（数字记不清了），请问小明一共有几天假期。
111.有个人在星期三写了一篇日记什么的，从今以后每天写一篇，共写了一千篇，问第一千篇是星期几？
114.<V4> the integer N can be expressed in this way: the sum of numbers made by a consecutive list 1 2 3 4 5 (note the word consecutive, it means the order should be 12345, not 13245 or 23415 etc), and you should put 2 plus sign between them, for example, 12+34+5 = 51 (warn: the N does not need to be a number consisted of 12345, in the example, 1 appear twice!), is N even?
1) N is 3 digit
2) one of the two plus sign is between 1 and 2
