| In the early days of the old West in
North America, life was difficult. People lived on farms far away from other
families. And there were some big problems. For example, how did one family make
a house What did families do to build houses They asked for help. They invited their friends and neighbors to a work party for a few days. The women cooked together. The men worked on the building. For the children it was like a holiday. Together these people built a house or a barn (谷仓). At another time the family with the new house would help their neighbors. A work party is really cooperation. To cooperate means "to work together". Many people can work together, hen the big job becomes a small job for many workers. Working together can be fun too. Today there isn’t much cooperation. [简答题]回阳散功效与作用

Less Is More
It sounds all wrong-drilling holes in a piece of wood to make it more resistant to knocks.But it works because the energy from the blow gets distributed throughout the wood rather than focusing on one weak spot.The discovery should lead to more effective and lighter packaging materials.Carpenters have known______(51) centuries that some woods are tougher than others.Hickory（山核桃木）,for example, was turned into axe handles and cartwheel spokes（轮辐）because it can absorb shocks without breaking. White oak,for example,is much more easily damaged,______(52)it is almost as dense.Julian Vincent at Bathe University and his team were convinced that the wood's internal structure could explain the differences. Many trees have tubular（管状的）vessels that run _______(53) the trunk and carry water to the leaves.In oak they are large,and arranged in narrow bands,but in hickory they are smaller,and more evenly distributed.The researchers_______(54)this layout might distribute a blow's energy throughout the wood,soaking up a bigger hit.To test the idea,they drilled holes 0.65 millimetres across into a block of spruce（云杉）,a wood with ________( 55 ) vessels , and found that______( 56 ) withstood a harder knock.______(57)when there were more than about 30 holes per square centimetre did the wood's performance drop off. A uniform substance doesn't cope well with knocks because only a small proportion of the material is actually______(58).All the energy from the blow goes towards breaking the material in one or two places , but often the pieces left ______（59 ) are pristine（未经破坏的）. But instead of the energy being concentrated in one place,the holes provide many weak spots that all absorb energy as they break,says Vincent."You are controlling the places_______(60)the wood breaks,and it can then absorb more______(61),more safely."The researchers believe the principle could be applied to any material________(62)example,to manufacture lighter and more protective packaging.It could_______(63)be used in car bumpers,crash barriers and armour for military vehicles,says Ulrike Wegst,a_______(64)at the Max Plank Institute for Mental Research in Stuttgart. But she emphasizes that you______(65)to design the substance with the direction of force in mind. "The direction of loading is crucial,"she says. 62._________ A.among B.in C.as D.for [单项选择]实行PMS的船舶，船公司主管部门应提前（）个月将月计划指令下发船上。
