16世纪末，伽利略用实验和推理推翻了已在欧洲流行近两千年的亚里士多德关于力和运动的观点，开启了物理学发展的新纪元．以下说法中与亚里士多德观点相反的是（ ）
A．两物体从同一高度自由下落，较轻的物体下落慢
B．用力推车车前进，撤去推力车就停下来，说明运动需要力来维持
C．石头和羽毛在真空环境下下落一样快
D．一个物体维持匀速直线运动，不需要力
A、两物体从同一高度自由下落，较轻的物体下落较慢，即重物比轻物下落快，是亚里士多德的观点．故A错误．
B、力是维持物体运动的原因，物体受力就会运动，不再受力了，它总会逐渐停下来，是亚里士多德的观点．故B错误．
C、石头和羽毛在真空环境下下落一样快，证明了不是重的物体下落快，与亚里士多德的观点相反．故C正确．
D、伽利略用实验和推理，证明了力不是维持物体运动的原因．故D正确．
故选CD
完形填空 Mr. and Mrs. Jones don’t often go out 36 , but last Saturday, Mrs. Jones 37___ to her husband, “There is a good 38 tonight. Can we go and see it?” Mr. Jones was quite 39 about it, so they went and both of them liked the film very much. They came out of 40 at 11 o’clock, got into their 41 and began to drive home.
