结合上述资料，用200字左右的篇幅分析我国安全生产问题频发的深层次原因。要求：分析深刻，条理清晰。
参考答案：第一，经济快速增长，增长方式落后。经济快速增长给安全生产带来了挑战。
第二，长期投入不足，安全欠账严重。特别是煤矿、重化工企业，投入不足不仅是安全投入不足，基础产业更是投入不足。
第三，行业管理弱化，企业管理滑坡。监管不扎实，执法不严格，责任不落实，措施不到位。
第四，农村劳动力转移。农村劳动力的安全生产意识比较淡薄，要对其进行安全生产的培训，提高其安全生产意识。
第五，我国煤矿地质条件和其他国家不能比。和美国、西方发达国家甚至和发展中国家比先天不足，井工矿占95%，露天矿太少了。我国高瓦斯矿占46%，煤层容易自燃的占一半，条件比较恶劣。
阅读下列短文，根据短文中的信息完成文后表格。在答题卡标有题号的横线上，写出空缺处所填单词的正确形式。（每空一词） ‘USA? Britain? Which country is better to study in?’ We often hear such discussions. As China opens its door, it is a dream for many Chinese students to study abroad. They want to learn about the outside world. It’s true that studying abroad can help students develop themselves. Their foreign language skills will be improved and it may be easier to find jobs. But there are problems that should be considered. Language is the first. Students must spend a lot of time learning another language. Students must also learn to live without parents’ care and deal with all kinds of things they haven’t had to do before, like looking after themselves. There are reports about Chinese students abroad running into an ocean of difficulties and giving up finally. When they have to take care of themselves, it is hard for students to study well. Finally, studying abroad brings a heavy burden（负担）to the family. For most Chinese parents, the cost of studying abroad is very high. But is it worth it? We know that there are many famous people who have achieved success through their hard work in China. Liu Xiang is a good example. Once an American teacher invited him there, but he refused. He kept training hard with his Chinese teacher. He surprised the world when he won a gold medal at the Athens Olympic Games. So when you wonder which country is better to study in, think again.
