All of us know that ordinary movements—things as running, jumping, 【M3】______
and bending— made possible by muscles. Muscles also do many other things. 【M4】______
They suck air into your lungs, push food along your digestive tract, and tighten your blood vessels to raise blood pressure when you need more pressure for an emergency. Your heart is a muscular pump.
When your muscles are not used, or are not used enough, they do not develop and grow
proper. They soon become flabby and weak, shrink in size, 【M5】______
and lose the ability to do the jobs they were mean to do. 【M6】______
Recent studies showed that the average high school student spends fifteen to thirty hours a week watching television and only two hours a week in organizing play or exercise. 【M7】______
That is one reason why one-third of the 200,000 pupils tested for the President’s Council on Physical Fitness failed a simple test of strength, stamina, and flexible. 【M8】______
Some of the boys and girls could not raise themselves to a sitting position without
used their hands! 【M9】______

reduce strenuous physical activity. But our bodies still need exercise. Without it they soon become weak, ineffective, and unattractive.
【M6】
选项
答案
mean→meant
解析
语态错误。句中的动词“mean”前面的同是be的形式,这里既然不可能是进行时,那么应该用动词的被动语态,原句they were mean to do中的mean没有变化成过去分词,应该改为meant。
