Say you meet with difficulty, what’s the first thing you do? Call your best friend and ask for help? It turns out that doing this may be better for you than you think. Researchers find that friendship has a big influence on your health, well-being and business.

One study from scientists recently found that older people with a large circle of friends were 22% less likely to die during a 10-year period than those with fewer friends. Other researchers discovered that having a strong social network could improve brain health as we age.

Even more interesting, feeling close to your friends may give you a different view on things. Researchers gathered 34 college students out side and asked them to estimate the steepness(估计陡峭程度) of a hill after climbing it. Those standing with friends gave lower estimates, and the longer the friends had known each other, the less steep the hill appeared.

What is the reason that friends can make obstacles seem less difficult? “People with stronger friendship networks feel that there is someone they can turn to,” said Karen A. Roberto, director of the center of the hospital at Virginia Tech. “Friendship is a valued resource (宝贵的资源).”

It is truly the fact. Friends make your life better. They provide support in hard times. They inspire you to make changes in your life, encourage you to set goals and cheer you on every step of the way until you reach them.

阅读以下材料,说说以下化学探究活动是由哪些环节组成的,将其分别填在相应的括号内.

燃烧是我们经常接触到的一种化学变化.它与我们的生活密切相关.燃烧为人类带来了光明,如果失控也会给人类带来灾难.因此,人类必须了解物质为什么会燃烧,才能控制燃烧,使其更好地造福于人类.

小童想:物质燃烧需要哪些条件?(______)

(1)可能需要一种可以燃烧的物质;

(2)可能需要一定的温度;

(3)可能需要氧气.(______)

小童设计了实验方案:

实验1:用镊子分别夹取一小木条和小石子,将它们分别放在酒精灯外焰上加热,观察实验现象.

实验2:用镊子分别夹取一小纸片、小木条、小煤块,分别在酒精灯上点燃,观察实验现象,比较三者点燃的难易程度.

实验3:在桌面上点燃两支蜡烛,在一支蜡烛上方罩上250mL烧杯,观察实验现象.(______)

小童对实验现象进行了记录和分析:

 实验现象 得出的结论 
 实验1小木条燃烧了,小石子不燃烧.燃烧需要可燃物 
 实验2小纸片最易燃烧,小木条次之,小煤块最难燃烧. 燃烧需要达到可燃物燃烧所需的温度. 
 实验3 桌面上的蜡烛正常燃烧,罩上烧杯的蜡烛燃烧一会儿就熄灭. 燃烧需要氧气.
小童归纳总结,得出燃烧的条件:可燃物;温度;氧气.(______)

小童觉得,通过这次探究活动,知道了燃烧的条件,能解释钻木取火、森林灭火等现象和原理,并且体验了像科学家一般探究学习的乐趣.(______).
