问题 解答题

王老师带领五年级一班同学去植树,一共植树148棵,已知王老师和每个同学植的树都一样多,五年级一班同学正好能站成三路纵队。你知道每人植了几棵树吗?五年级一班有多少名同学?

答案

148棵树应该是总人数和每人植树棵的倍数,再来考虑人数,五年级一班人数应是3的倍数,那么总人数应是3的倍数多1。148=1×148,148=2×74,148= 4×37

①148=1×148= 147+1= 49×3+1,每人植树1棵,五年级一班有147人。(一个班不可能有这么多人)

②148= 4×37= 4×(36+1)= 4×(12×3+1),每人植树4棵,五年级一班有36人。

完形填空

根据短文内容,从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Are you a team person? Are you at your best as part of a small, tightly united group of dedicated workers? If so, the future may hold more for you than you think.

小题1:   That’s happening in those areas of business and data processing where one person and a computer can replace a team of workers.

小题2: High technology has led to a new type of teamwork in a number of fields, including advertising, scientific research, engineering design, architecture and ocean exploration.

Through computer networking, scientists, engineers, and technicians at different locations — often thousands of miles apart --- can work on the same project at once.    小题3:   

Examples? An engineering team can now design and try out a robot system --- a new manufacturing process, or an entire factory — before it is built. An architectural team can do the same with a building or a bridge. A medical team can simulate a dangerous operation before performing it on a patient.

Of course, computer-assisted team effort doesn’t end with investigation and simulation.  小题4: “CAD-CAM --- computer-aided design and manufacture --- is breaking down barriers between traditional design and manufacturing functions.” explains Dr. Prakash Rao, an engineering manager at General Electric. “Interdisciplinary(跨学科的) teams and engineers follow a product from concept to production. Everything is interconnected like a network.”

小题5:  A team that produces robots may use them to explore space and ocean depths. For high-technology teamwork, the future seems limitless.

A.They can exchange ideas, try out different designs, and test their results.

B.It now usually continues into actual design, manufacturing, and testing.

C.In the future, team work will be highlighted by the introduction of new technology.

D.Sometimes, a computer-aided effort can extend beyond production.E. But, elsewhere, teamwork is very much alive.

F. It ends in the products which are extensions of the traditional design.

G. High technology, some predicted, would make team work a thing of the past.
