阅读下列短文,根据短文中的信息完成文后表格。在答题卡标有题号的横线上,写出空缺处所填单词的正确形式。(每空一词)
Recently, the relationship between the two countries got worse because of the Diaoyu Islands.
The Japanese government signed a contract(合同) on Sep 11 with the Kurihara family. It was to pay the so-called “private(私人的) owner” 2.05 billion yen (166 million yuan) to “buy” part of China’s Diaoyu Islands.
Anti-Japan(反日) feeling grew strongly among Chinese people. Many people walked into the streets and shouted out “Diaoyu Islands are China’s.” Some have decided not to buy Japanese products any more. “I am boycotting(抵制) Japanese goods as a show of support. I’ll work hard to make the country much stronger,” Liu Xiushan, 33, a lawyer in Beijing said to China Daily.
However, some didn’t show their anger in the right way. They broke cars and stores of Japanese brands. Some used rude words. These actions are bad for our position and image. Some actions were against law.
Li Jingjun, a 17-year-old high school student in Guangzhou, was shocked by what he learned from TV and the Internet. He joined protects(抗议) in his city on September 15. But he acted differently. He called for rational (理智的) actions.
“We have every right to say the Diaoyu Islands belong to us, but we should watch our behaviour. Bad manners can harm our dignity(尊严) and sense of justice(正义感)” ,said Li Jingjun.
