(7.21)
If you weigh 90 pounds, you ________ to the earth by a gravitational force of 90 pounds
意思是如果你重90磅,你已经受到90磅的地球引力。引力造成了体重90磅,对现在结果造成了影响,所以用现在完成时
If you weigh 90 pounds, you have been pulled to the earth by a gravitational force of 90 pounds.
如果您称90 磅, 您被拉扯了对地球由90 磅引力。
分析可得,是你“已经”“被”(地球)拉扯了对地球由90 磅引力,所以用现在完成时的被动语态形式,所以用have benn pulled。
是受到地球的重力吧 拉扯比较费劲
