伽利略通过对自由落体运动的研究,把实验和逻辑推理和谐地结合起来,从而发展了人类的科学思维方式和科学研究方法。下列说法正确的是(     )

A.伽利略首先建立起平均速度、瞬时速度及加速度等概念

B.伽利略运用逻辑推理推断出重物与轻物应该下落得同样快

C.伽利略靠滴水计时的方法测量出了物体自由落体运动所用的时间

D.伽利略把日常生活中见到的较重的物体下落得比较快的原因归之于空气阻力对不同的物体的影响不同

答案

ABD

A、伽利略首先建立了平均速度,瞬时速度和加速度等概念用来描述物体的运动,并首先采用了实验检验猜想和假设的科学方法,把实验和逻辑推理和谐地结合起来,从而有力地推进了人类科学的发展.故A正确

B、伽利略通过逻辑推理的方法,否定亚里士多德统治人们2000多年的理论,伽利略的猜想是轻、重两物体下落得一样快,只是猜想,并未推断出,故B错误.

C、伽利略靠滴水计时的方法测量出了物体自由落体运动所用的时间,故C正确

D、伽利略把日常生活中见到的较重的物体下落得比较快的原因归之于空气阻力对不同的物体的影响不同,故D正确

     [1]Everyone has dreams. Usually they obey the rule that if you can dream it, you can achieve it!If you

want to obtain a perfect life in the future, there are always some goals.

     [2]The first goal common to all of us is health and energy. We all want to be healthy and fit, to have

high levels of energy and to live free of pain and illness. Today, with the incredible advance in medical

science, the quality of our health and fitness, and our lifespan is largely determined by design, not by

chance. People with excellent health habits are far healthier, have more energy, and live longer and

better than people who have poor health habits. Remember that health is not everything, but without

health everything is nothing!

     [3]The second goal that we all have in common is to enjoy excellent relationships-personal or

social-with  the people we like and respect, and who in turn. Fully 85% of your happiness will be

determined by the quality of your relationships at each stage, and in each area of your life. How well

you get along with people, and how much they like and respect you, have more impact on the quality

of your life than perhaps any other factor.

     [4]The third common goal is to do work that we enjoy, to do it well, and to be well paid for it. You

want to be able to get and keep the job you want, to get paid more and promoted faster. You want to

earn the very most that is possible for you at each stage of your career, no matter what you are engaged

in.

     [5]The fourth goal we all have in common is to achieve financial independence. You want to reach the

point in life where you have enough money so that you never have any financial worries. You want to

be completely free of them. You want to be able to order dinner in a restaurant without referring to the

price listings to determine what you want to eat.
