News Report Two

    The Tunisian government said on Monday that 45 people have been killed after gunmen attacked a town near the border with Libya. 

    The Interior and Defense ministries said that the Tunisian government（3）has closed its two border crossings with Libya because of the attack. 

    The Tunisian military has sent reinforcements and helicopters to the area, and authorities have been hunting several attackers who were still at large. 

    The violence came amid increasing international concern about Islamic State extremists in Libya. Officials of the Tunisian government are especially worried after dozens of tourists were killed in the attacks in Tunisia last year. 

    Defense Minister Farhat Horchani said last week that German and American security experts were expected to come（4）to help Tunisia devise a new electronic video supervision system on its border with Libya. 

    Tunisia was targeted last year by three attacks that left 70 people dead and were claimed by Islamic State.

3. What did the Tunisian government do after the gunmen’s attack?

解析：C。该题目为细节题。问题为：枪击事件后，突尼斯政府采取了什么措施？根据问题关键字“Tunisian government”“attack”定位文章出处：The Interior and Defense ministries said that the Tunisian government has closed its two border crossings with Libya because of the attack. 内政和国防部表示突尼斯政府已经关闭了邻近利比亚的两个过境处。选项C）It shut down two border crossings with Libya，与原文内容含义一致。选项中shut down和 close为同义替换，译为“关闭”。因此正确答案为C。
