    Different weather makes people feel different．It influences health，intelligence and feelings．
    In August，it is very hot and wet in the south the US．People there have heart trouble and other kinds of health problems during this month．In the Northeast and the Middle West，it is very hot in the summer and very cold in the winter．People in these states have more heart trouble after the weather changes in February or March．
    The weather can also influence intelligence ． For example，in a 1983report by scientists，IQ(智商)of a group of students was very high when a very strong wind came, but after the strong wind,
    Their IQ was 10% lower than before. The wind can help people have higher intelligence. However,very hot weather can make it lower. Students in many schools of the US often get worse in exams(考试)in the hot months of the year(July and August).
    Weather also has a strong influence on people's feelings．Winter may be a bad time for thin people．They usually feel cold during these months．They might feel unhappy during cold weather．But fat people may have a hard time in hot summer．At about 18℃people become stronger．Low air pressure may make people forgetful．People leave more bags on buses and in shops on low-pressure days．
    Are you feeling sad，tired，forgetful，or unhappy today？It may be the weather's problem．

20世纪以来的三大理论对中国社会发展产生了重大影响。根据提示，完成下列有关三大理论的探究任务。

材料一  ……我们完成了孙先生没有完成的民主革命，并且把这个革命发展为社会主义革命。我们正在完成这个革命。

                                ——***《纪念孙中山先生(1956年11月12日)》

材料二  ***思想的基本点就是实事求是，就是把马列主义的普遍原理同中国革命的具体实践相结合。……***同志所以伟大，能把中国革命引导到胜利，归根到底，就是靠这个。马克思、列宁从来没有说过农村包围城市，这个理论在当时世界上还是没有的。但是***同志根据中国的具体条件指明了革命的具体道路，在军阀割据的时候，在敌人控制薄弱的地区，领导人民建立革命根据地，用农村包围城市，最后夺取了政权。……我们高举***思想的旗帜，就要在每一时期，处理各种方针政策问题时，都坚持从实际出发。

         ——邓小平《高举***思想旗帜，坚持实事求是的原则(1978年9月16日)》
