试题题干
Fill in the blanks with an item as required.
With an appropriate conjunctive:
The relations between the two countries are improving: a trade agreement has been signed
a culture exchange arranged.
参考答案
试题解析
本题考查并列连词的用法。a trade agreement signed和a culture exchange （has been）arranged 是并列关系，都是两国关系改善的表现。所以填一个并列连词and。
句意：两国关系正在改善：双方签署了贸易协定，并安排了文化交流。
