问题 填空题

关节在运动中起______作用,是骨绕着转动的点.(P29)

答案

骨骼肌一般要跨越一个或是几个关节,由肌腱附着在相邻的骨上.骨和关节本身没有运动能力,必须依靠骨骼肌的牵引来运动.当骨骼肌受到神经传来的兴奋刺激后,就会收缩变短,并产生一定的拉力,牵动骨围绕着关节活动,从而产生运动.因此,关节在运动中起着支点的作用,骨起着杠杆的作用,骨骼肌起着动力的作用.

故答案为:支点

What makes a house a home?

Not size, of course. I’ve been in some of the grandest houses in America and it’s readily apparent no one lives there. Earlier this year in a mud hut in Ethiopia, where we sat on chairs next to the hostess’s bed—a home that had more warmth than any house I’ve been in since.

Now John Edwards is exploring what makes a house a home in his just-released book-- The Blueprints of Our Lives. There Edwards writes, “ This is a book about homes, the values they rest on, the dreams they are filled with, and the people they have shaped. The houses and circumstances (环境) are different, but much of what you find inside will be familiar.”

Whether you’re sitting in an airport right now, waiting to fly to your childhood home for Thanksgiving, or in your own home waiting for the relatives to arrive, you know what he’s talking about.

We’ve lived in our townhouse for 21 years--the loose windows that make noise in the wind, the fireplace so shallow it holds only one log, the kitchen window that offers a view of the world passing by. It is where friends sit on the kitchen counter drinking wine while dinner is being fixed. I lived there for only 18, but it will always be my true home. Even the lamp in the west living room window, which I could see far down the road when driving home late at night, still shines.

While all this talk about childhood memories can be warm and comforting, home is whom you’re with, not where you are. As Edwards writes, “ Home is family. Home is safety. Home is faith.”
