Living closer to open fields and trees reduces your risk of being obese(肥胖), research suggests and the benefits can be seen even in poor neighborhoods where risks of both obesity and poor mental health are known to be much higher. The newstudy, supported by Friends of the Earth Europe (FoE), also showed that the great outdoors had benefits for pregnant women. Those living close to trees and openfields, considered a "natural healers" by the researchers at the Institute for European environmental policy, gave birth to children of much healthier sizes.It is believed that the increased opportunity to be active and breathing in less air pollution may explain the reduced death rates and obesity prevention. After reviewing hundreds of previous studies, scientists say it can even reduce the chance of an early death by 16per cent compared to those living in an "urban jungle." The green spaces also reduced depression (抑郁)by allowing for people to meet others more easily and get away from busy and noisy activities of a city, experts state.Robbie Blake, a campaigner for FoE, told The Guardian: "The evidence is strong and growing that people and communities can be energetic and lively when they have access to nature."We all need nature in our lives and it gives us freedom and helps us live healthily; yet poor communities are routinely cut off from nature in their surroundings and it is holding back their wellbeing."The findings back up much evidence that shows setting up a home in a heavily﹣polluted city can be damaging to someone's health. After studying the well﹣being of nearly110, 000 women, they found living in cities also increased the risk of cancer and respiratory (呼吸)illnesses. Those in the greenest areas had a 34 percent lower rate of respiratory disease﹣related deaths and a 13 percent lower rate of cancer deaths.(1)What can we know about obesity from Paragraph 1?________A The outdoors can prevent obesity.B Obesity can cause mentaltrouble. C Urban mothers can have obese babies. D Pregnant women can get obese easily.(2)What is the social benefit of living in the countryside?________A Having more freedom to rest.B Meeting other people moreconveniently. C Breathing healthier air. D Keeping more wealth and happiness.(3)What does the underlined word "We" in Paragraph 4 refer to?________A Pregnant women.B Patients with respiratory illnesses.C Ordinary people.D People living in poor communities.(4)What is the best title for the text?________A Ways of living in the countryside.B Living in healthyneighborhoods. C Countryside, the greenest area. D Access to nature.4. While there are a few ways to make use of your old smartphone, one of the better ways is to convert into a dash cam (行车记录仪) that you can use on your bicycle. With the camera, you can record your rides, which is especially helpful if you are involved in a crash with another vehicle.To use your smartphone as a dash cam on your bike, you will need to make sure it is properly secured to your bike. To do this correctly, you must take two strips of heavy﹣duty Velcro (a kind of cloth used as fastening) along with two pipe Clamps (管夹) and a flat corner brace (角撑) to properly attach ________.

【题文】阅读下面的材料,根据要求写作。
①白日不到处,青春恰自来。
苷花如米小,也学牡丹开。
一一清代诗人袁枚②时间,你不开拓它,它就悄悄长出青苔,爬上你生命的庭院,把你一生掩埋一一格言③让自己的内心藏着一条巨龙,既是一种苦刑,也是一种乐趣。
——雨果④欲速则不达,见小利则大事不成。
——春秋孔丘弟子⑤多少事,从来急;天地转,光阴迫。

要求自选角度,明确文体,自拟标题。

【答案】野百合也有春天清代诗人袁枚有一首赞美青苔的诗。
写青苔即使阳光照不到,花儿又小如米,却也依旧如牡丹般自豪地开放,绽放出亮丽的青春色彩。
弱小的苔花之所以能绽放自己,实现价值,就在于他坚定自信的行动以及不懈追求的作为。
自然告诉我,青苔和野百合也有春天;生活告诉我,只要自信和努力,凡夫俗子也能赢得属于自己灿烂的春天。
积极人生态度,会产生积极的生活目标。
人生在世,如白驹过隙。
突然地来临了,突然地离开。
而能在这个世界留下的,不是肉体,而是自己在世上所实现的人生价值。
好比中国历史,皇帝千百,而真正名垂青史的,不过秦皇汉武、唐宗宋祖等充分实现自己人生价值的贤明君主罢了。
挥一挥衣袖,不带走一片云彩,但不在世上留存点什么,岂不枉活一世,太可惜了。
因此,积极的人生态度就会引导我们积极去奋斗,最终实现人生价值。
积极生活目标,必将产生强大的内驱力。
有了积极的人生态度就能成功吗?我认为还需要强大的内驱力,驱使我们来实现这些目标。
生命中有些东西是不能选择的,比如容貌、资质、物质条件等因素,因为平庸凡俗,因为贫困落后,因为自身条件差就放弃拼搏进取,这样的人生是没有出路的。
相反,愈挫愈勇,越贫越需改善,越差越需内涵,结果前途一片光明。

There a remore traffic accidents and more people are suffering from breathing problems becaus eof smog.There are some reasons for smog in China. First of all, too many cars give offwaste gas in the street. Second, a lot of fossil fuel like coal, petrol and naturalgas is consumed in factories, which produces too much carbon dioxide. Bes ides, Chinahas many smokers, who are making smog even worse.It is time for us to fight against smog. We had better walk or ride to school to reduce the consumption of fossil fuel. We should plant more trees to absorb poisonous gas in the air. Besides, it can help improve the air quality to persuadepeople around us to give up smoking.Let’s take immediate action to fight against smog.Li Hua。
