一般annoying inventions好像总和环境问题有关我觉得。。 vehicles - huge carbon emissions cause global warming! disposable chopsticks - destruction of forests nuclear weapons - undoubtedly a threat to our environment and peace of the world 还有比如 cctv（不是中央电视台，是英国的监控系统 哈哈 我觉得也蛮annoying的）people feel loss of privacy hope this is of some help! cheers! :)))
