查询技巧:
1、输入单个单词准确查询。
2、使用%模糊查询,匹配任意长度字符:
   %a    以a结尾的单词;
   ab%    以ab开头的单词;
   %ac%    含有ac的单词。
3、使用_模糊查询,匹配单个任意字符:
   _a_    三位且a在中间的单词;
   _ad    三位且ad结尾的单词;
   ac_    三位且ac开头的单词;
   _a    两位且a结尾的单词;
   a_    两位且a开头的单词。
4、带连字符-的单词,需含-字符才能模糊查询,如well-know需输入 well-% 。
5、在手机键盘上,如果g上有%和v上有_,则可长按输入。

Olympiads

1. After Los Angeles, cities around the world began to vie to host Olympiads.
洛杉矶奥运会之后,世界各大城市开始争夺奥运会的主办权。
2. The physics competition is one of the International Science Olympiads held around the world.
该物理竞赛是在世界各地举行的国际科学奥林匹克竞赛的之一。
3. Whereas in earlier Olympiads Americans shone mostly in track and field, in Paris they took the lead in almost every venue.
在往届奥运会上,美国人士多在田径项目上独领风骚,而在巴黎他们几乎在所有项目上居领先地位。
4. China has been participating since only 1985, which makes its record all the more impressive: it has won almost two-thirds of the Olympiads it has competed in.
直到1985年中国队才首次参与国际数学奥林匹克竞赛,所以创下的记录是令人印象深刻的:中国队几乎赢了三分之二参加过的比赛。
5. There are of course several other problem-solving books, such as Polya’s classic “How to solve it“, which I myself learnt from while competing at the Mathematics Olympiads.
当然还有其他关于数学解题的书,如数学教育家 Polya 的经典之作《如何解题》,我参加奥林匹克数学竞赛时曾从中获益非浅。
