How do you explain that we are moving?
We cannot feel speed. But our senses let us know that we are moving. We see things moving past us and feel that we are being shaken. We can feel acceleration, an increase in speed. But we notice it for only a short time. For instance, we feel it during the take-off run of an airplane. We feel the plane’s acceleration, because our bodies do not gain speed as fast as the plane does. It seems that something is pushing us back against the seat. Actually, our bodies are trying to stay in the same place, while the plane is carrying us forward.
Soon the plane reaches a steady speed. Then, because there is no longer any change in the speed, the feeling of forward motion stops.
选项
A、That we are being thrown forward.
B、That we are pushed back against the seat.
C、That we are lifted out of the seat.
D、That we are pushed down into the seat.
答案
B
解析
题干问:“飞机起飞的时候,我们感觉怎么样?”听力材料中说:“It seems that something is pushing us back against the seat.”这和答案B的意思一致,所以本题答案选B。
