问几个超简单的选择题，说下理由，谢谢

BABCA

1题.是虚拟语气和被动态两个原因使我们要选B.虚拟语气的基本句型是It is suggested that （should）do．这里should可以省略也可以不省略，根据实际需要．do就表示要动词原形了．这个句子中，学校是被修建的．所以要用被动态be set up．

2题.只有A才说的通啊.B. wherever(随便哪里)前面已经说了in my restaurant ,你再用个wherever来修饰就矛盾了啊.同理C. whatever 也与food矛盾.D. however 与 free相矛盾了.

3题.an expert on sth.是固定搭配哈.没有expert of这种用法.

4题.the last city 中修饰词是the last.所以定语从句后面的先行词就要用 that . 这是语法规律哈。

5题.leave是一个可以用现在进行时表将来的词语.题目中is leaving 就等于will leave了．

回答完了．不要讲解的是错误的答案，那就不好意思了．你就假装没看见吧．
