阅读下面短文和问题，根据短文内容，在相应题号后的横线上写下相关信息（不多于五个单词），

     Human activities have great effect on the environment. Everyone can make small life changes toward

a low-carbon (低碳) life. Such changes can not only make a difference for the environment, but also have

great health benefits for you.

     ● Burn less gas. Try walking or bicycling to work a few times a week and get a healthy exercise on the

way. Encourage children to walk to school. Cutting down on driving and using your own two legs helps

cut global warming pollution and helps deal with weight problems over time.

     ● Eat more thoughtfully. Eat less meat and more grains and vegetables, which helps reduce the need to

change forests or grasslands to pasturelands (牧场). Replace one or more of your weekly meals with a

meatless meal.

     ● Drink tap water rather than buy bottled water. Bottled water produces up to 1.5 million tons of plastic

waste per year. Bottled water is not necessarily cleaner than tap water, and tap water is cheaper.

     ● Reduce the use of paper. Think twice before you print. If you must print, try printing on both sides.

     ● Reduce the amount of water you use in your home. Turn off the water while brushing your teeth and

turn off the shower after soaping up. Wash your fruits and vegetables in a basin of water instead of running

water from the tap.

     ● Use energy-saving lamps to save money, use less energy and create less pollution. These lamps are easily

available and have various styles and brands.

有孪生二兄弟，当他们长到二十岁的时候，各自选择了自己的职业。哥哥立志于天体研究，并且当上了宇宙航行员。哥哥要出发了，弟弟去送行，临别前，他们俩相互对了对手表。哥哥以接近光速的速度在宇宙飞行了四年半。当他就要返航时，他给弟弟发了一份电报，弟弟欣然去迎接他哥哥，当他们重新见面时，哥哥以为是父亲来了，因为站在他面前的已是一位两鬓斑白的老人了。弟弟告诉哥哥说：“你“去有三十二年，我的孩子已经有二十四五岁了。”爱因斯坦的狭义相对论证明，空间、时间是随物质运动速度的变化而变化的，当物体以接近光速的速度运动时，物体沿前进方向的空间会缩短，内部过程会变慢：相对论效应只有在速度很高以至接近光速时才很显著。我们日常生活中见到的最大速度，只不过每小时一千公里的量级。在这种速度下，上述现象是无法从直观上看出来的。这些事实表明（）。

A．认识事物要透过现象抓住本质

B．时间和空间与物质运动是不可分离的

C．存在两种不同的时空

D．“哥哥天上正年少，弟弟地上已暮年”说明时空与运动是一致的
