督查组接到群众反映，调查走访后作出的反馈是符合陕西省实际情况的。

②完善社会主义市场经济体制，需要市场在资源配置中起决定性作用。

但市场调节存在着自发性等弊病，当地某些小微市场主体为了自身不正当的利益，损害了社会的公共利益。

所以，还需要更好地发挥政府作用，加强市场监管，规范市场秩序，保障公平竞争，以弥补市场缺陷。

③针对小微市场主体的多起行政处罚中，罚款金额远远高于案值，当地执法部门只讲罚款力度，没有考虑到小微市场主体的生存艰辛。

因此，政府应坚持以人民为中心的发展思想，切实履行经济职能，优化公共服务，以保障社会公平正义，为小微主体的生存创造良好的营商环境。

④因此，结合国务院督查组的反馈，当地政府应尽快制定整改方案，聚焦问题，统筹好执法工作和服务市场主体。

（2）①坚持党的领导，确保地方治理在党的领导下始终沿着正确政治方向前进。

把法治政府建设作为全面依法治国的重点任务和主体工程推进。

②坚持依法履行法定职责，加强市场监管、优化公共服务，加快转变政府职能，为小微主体的生存创造良好的营商环境，维护经济发展秩序。

③坚持有法必依、执法必严、违法必究，严格规范公正文明执法，重点规范行政处罚等执法行为，恰当地行使自由裁量权，在法治营商环境建设中提高执法公信力。

④要全面推进政务公开，通过公开公正执法，有效保障入民群众的知情权、参与权、表达权、监督权，聚焦群众关心的问题，统筹好我法工作和服务市场主体。

⑤要提升行政执法水平，执法不能只讲力度，让人民群众在我法中感安到公平正义，保护人民群众合法权益，把权力用来为人民谋幸福。

This time, Nate saw her. His eyes narrowed, and he jumped in to help her.Just then, Nila felt someone’s arms grabbing her from behind. “Lie back,” her sister’s voice said. “I’ve got you.” Much to her surprise, it was at the critical moment that Lexi came to her aid! They got out of water quickly. “How are you feeling?” Lexi asked. “OK. That’s a little scary.” “Don’t worry,” Lexi said, “Next time we go swimming, I could keep you company. With more practice, you can surely pass Level 4.” Hearing this, Nila smiled broadly, a current of warmt h flooding over her, saying “You will be a good lifeguard someday because you’re already a good sister.”听力原稿：Text 1W: I’m sorry to bother you, but I can’t read the sign at this bus stop.

The virus has caused many people to work from home. If companies decide to continue allowing this, it will ease the burden on public transport. (18) Many train and subway systems in major cities were struggling with the number of daily passengers. With restrictions and social distancing in place on many modes of transport, people have been shifting towards cycling as an alternative way to get around. During June 2020, the UK saw cycling levels rise by 300%.(19) This was pushed by a government policy that allowed people to buy a bike tax free, allowing savings from 25% up to 39% depending on the cost of the bike. The coronavirus has also seen significant impact on jobs, with over 650,000 people in the UK having lost their roles during lockdown, mainly in the retail(零售) and service section. However, other sections such as technology were much better as people try to find technical solutions to lockdown, such as video calling. Although it has been a shock, the world has adapted quickly to coronavirus, and many are hoping that these changes are here to stay, (20) highlighting the fact that traditional ways of living and working should remain in the past.。
