问题 单项选择题

41~45题基于以下题干:
一农民买了5种化肥,由于仓库地方有限只能将化肥袋子紧贴着排列放置,每个袋子内装一种化肥。化肥会从编织袋中渗出,如果起反应,将降低肥效,所以不能把两种能起反应的化肥装在相邻的袋子中。该农民的化肥种类有N,K,L,M和W,这些化肥仅有的反应关系如下:
N与K反应,N和K不能相邻;
W与K反应,W和K不能相邻;
N与L反应,N和L不能相邻;
L与M反应,L和M不能相邻。

若4种化肥分别属于N,K,L和M被放在4个连续的袋子内,但不一定按给出的顺序,则 M一定被放置在与谁相邻的位置

A.N和这一排两端的某个袋子。

B.L和这一排两端的某个袋子。

C.K和N。

D.N和L。

答案

参考答案:C

解析:N不与K相邻,也不与L相邻,则N只能与M相邻,N必然靠一端。由条件L和M也不相邻,则这4种化肥只能按N,M,K,L或L,K,M,N的顺序排放,所以与M相邻的只能是N和K。

There are three kinds of goals: short-term, intermediate and long-term goals. Short-term goals are those that usually deal with present activities. Such goals can be achieved in a week or two, or possible months. It should be remembered that just as a building is no stronger than its foundation (基础), our long-term goals cannot be achieved without the achievement of solid short-term goals. Upon completing our short-term goals, we should date the time and then add new short-term goals that will build on those that have been completed.

The intermediate goals build on the foundation of the short-term goals. They might deal with just one term of school or the entire school years, or they could extend for several years. Any time you move a step at a time, you never allow yourself to become discouraged. As you complete each step, you will have more belief in your ability to grow and succeed.

Long-term goals may be related to our dreams of future. They might cover five years or more. Life is not a static (静态的) thing. We should never allow a long-term goal to limit us or our course of action.
