问题:

这是王聪同学设计的“中国象棋数字编码方案”,读一读王聪的编码方案,根据编码方案填相应的数字编码.

中国象棋棋子共有车、马、相(象)、仕(士)、帅(将)、兵(卒)、炮等7个兵种.行棋有平,前(进),后(退)3类.这样正好满足了数字0-9.

如果用棋子名在列线的位置号做为棋子号的话,就会产生以下编码:

1-车2-马3-相(象)4-仕(士)5-帅(将)7-兵(卒)8-炮

那么就剩下数字0,6,9了.

6的“小尖尖”不是向上指的吗?不就是前进的意思吗?同样,9的“小尖尖”不是向下指的吗?不就是后或退的意思吗?留下的0不说也知道了--那是不进不退只有横着走了,难道不就是“平”吗?

哈哈!原来什么事情分析出来后就划如此的简单!“中国象棋数字编码方案”几下就被剖编出来了:1-车2-马3-相(象)4-仕(士)5-帅(将)7-兵(卒)8-炮0-平6-前(进)9-后(退)

棋谱举例:

(1)炮二平五马8进7编码为:82052867

(2)马二进三车9平8编码为:22631908

写出下面棋谱的编码.

(1)前兵进一______后炮退三______

(2)前车平三______后卒平四______.

考点:数字和编码

A quarrel at home may result in your falling ill. Don’t laugh, it’s true. Family matters including living habits and even the way we speak have a big effect on our health, doctors say.

Wang Xiaoyu, a Senior 2 girl from Xichang, Sichuan Province, fainted (晕倒) in class when she heard her classmates quarrel at the top of their voices. Quarrels between her parents also put the girl into a coma. It is because she is suffering from depression (抑郁症), caused by bad relations at home, doctors explained.

“We don’t get sick or stay well by ourselves,” says Dr Robert Ferrer from the US. Ferrer shows that family forces may explain up to a quarter of health problems, in his recent research. The genes you get from your family may cause illness. If one of your parents has a heart attack, your risk of being affected may double. But effects on health are not only written in our DNA.

Unrelated people who live under the same roof also get similar problems. Diet, lifestyle and environment affect our health, too. Ferrer’s research also found that if teenagers feel they are ignored or unimportant at home they are more likely to get sick.

We may never fully understand all the effects that families have on our health. But just as individual (个别的) problems can have effects on others, a small improvement can have big benefits, Ferrer said.

小题1: Which of the following can best explain why Wang Xiaoyu fainted in class?

A.Because her classmates often quarreled in class.

B.Because her parents used to quarrel.

C.Because of her depression caused by bad family relations.

D.Because her classmates shouted loudly at her.小题2: According to Dr Ferrer, which of the following statements is TRUE?

A.We get sick or stay well by ourselves.

B.Only the genes we get from our family have a big effect on our health.

C.Our health has nothing to do with diet, lifestyle and environment.

D.Teenagers who are ignored at home get sick more easily than those who are not.小题3: The underlined word “coma” in Paragraph2 probably means ________.

A.surprise

B.faint

C.tiredness

D.sadness小题4:The best title for this passage is ________.

A.Family relations.

B.The reasons why we get sick.

C.Family---- another cause to health

D.A research about health.
