1,A 2,B3,D4,B5,B6,B7,C8,A9,B10,C11,D12,A13,A14,B15, A不懂可以追问顺便吐个槽，楼主不要介意。不知道这到底是什么考试，到底是考计算机还是考语法。不过题肯定是中国人出的了，因为中国老师最会挖坑了。比如第一道题，很多人看到switch第一反应就是switch on。。打开程序嘛。。实际上这里是切换程序的意思。。好吧，既然是切换程序，就要在between和among里选了。。一看是多应用切换，大于2个，肯定是among了。。。结果这又是个坑，因为switch between是个固定搭配，跟数量没关系。。你说出题的人是不是犯贱呢？ 在国外，你说switch between也好among也好，大家都能听的懂，完全不影响沟通，退一万步，这尼玛和计算机有一毛钱关系吗？？
