Python 分析 35 年的考研英语真题词汇，解读孤独的考研大军！

一、数据介绍

本文统计的对象为1980年以来英语试卷所包含的词汇，并对其进行了分析和总结。

二、实现过程

1、加载基础词汇

bw = open('data/basic_words.txt')

basicwords = []

for eachLine in bw:

basicwords.append(sw.simplify_word(re.split("[^A-Za-z]", eachLine)[0].lower()))

#print re.split("[^A-Za-z]", eachLine)[0]

print(len(list(set(basicwords))))

basicwords = list(set(basicwords))

2、加载超纲词汇

3、词汇分析

def simplify_word(a):
 #如果已经可以判断是名词,动词,形容词,副词,连词
 if enumerate.is_noun(a) or enumerate.is_verb(a) or enumerate.is_adjective(a) or enumerate.is_adverb(a) or enumerate.is_connective(a):
 return a
 try:#测试是否为动词,如果是则返回
 enumerate.is_verb(enumerate.verb.present(a))
 return enumerate.verb.present(a)
 except:#否则继续检查
 pass
 
 #测试是否是名词
 if enumerate.is_noun(enumerate.noun.singular(a)):
 return enumerate.noun.singular(a)
 otherwordlist.append(a)
 #print a
 return a

4、加载大纲词汇

dagang = open('data/5495大纲词汇.txt')
dagangwords = []
for eachLine in dagang:
 dagangwords.append(sw.simplify_word(re.split("[^A-Za-z]", eachLine)[0].lower()))
 #print re.split("[^A-Za-z]", eachLine)[0]
print(len(list(set(dagangwords))))
dagangwords = list(set(dagangwords))

5、考研英语真题单词数据可视化

x33 = 1980*np.ones(33)+range(33)
x32 = 1981*np.ones(32)+range(32)
plt.figure('wordeachyear')
plt.plot(x33,wy.eywords_volume,'r--o',alpha = 0.5)
plt.grid(True)
plt.show()
plt.figure('notindagang')
plt.plot(x33,cgw.notindagang,'o-', alpha = 0.5)
plt.grid(True)
plt.show()
plt.figure('wn')
plt.plot(wy.eywords_volume,cgw.pnotindagang,'bo')
plt.show()
plt.figure('pchaogang')
plt.plot(x33,cgw.pnotindagang,'o-', alpha = 0.5)
plt.grid(True)
plt.show()
plt.figure('notinpast')
plt.bar(x33,nip.words_not_in_the_past, color = 'green', alpha = 0.5)
plt.grid(True)
plt.show()
plt.figure('wordsAppearLastTime')
plt.plot(x32, walt.es, 'b--o', alpha = 0.5)
plt.grid(True)
plt.show()
plt.figure('pwordsAppearLastTime')
#plt.axes([1980, 2013 , 0.35 ,0.6])
plt.plot(x32, walt.esr1, 'r-o')
plt.plot(x32, walt.esr2, 'b--o', alpha = 0.4)
plt.plot(x32, walt.esr3, 'y--o', alpha = 0.4)
plt.grid(True)
plt.show()
