牛津双解还是朗曼双解？

I used Longman a long time ago. The example sentences are the best among all dictionaries I've used. Longman also has a rule that the examples only use words from a 2000-word vocabulary. (There're exceptions and the exception words are clearly marked.) Back in the days without the Internet, example sentences in dictionaries are crucial to English study. Now you can find them with a Google search. But still sentences in dictionaries are guaranteed to be correct in grammar and spelling. I highly recommend it to the people studying English as a foreign language.

Off-topic: More freedom after Olympics

Blogspot.com and wikipedia.com used to be blocked in mainland China, until some time before the Beijing Olympics. I was not sure whether the blockage would be lifted after the Games. Now it's mid-October, two months after the Games. The two web sites seem to be still open in China. And it's said foreign journalists in China get extended freedom about street interviews. Regardless other problems, I'm glad to see the positive effect of the Olympic Games on China's progress.
