统计英文句子中的单词出现的次数，输出次数最高的5个单词及次数。 Twinkle,twinkle,little star,how I wonder what you are.Up above the world so high,like a diamond in the sky.When the blazing sun is gone,when he nothing shines upon.Then you show your little light,Twinkle twinkle all the night.

可以使用Python内置的collections模块中的Counter类来统计单词出现的次数，然后使用heapq模块的nlargest函数找到出现次数最高的前5个单词。

代码如下：

import collections
import heapq

# 英文句子
sentence = "Twinkle,twinkle,little star,how I wonder what you are.Up above the world so high,like a diamond in the sky.When the blazing sun is gone,when he nothing shines upon.Then you show your little light,Twinkle twinkle all the night."

# 将句子中的标点符号替换为空格，然后按空格分割成单词
words = sentence.replace(",", " ").replace(".", " ").split()

# 使用Counter类统计单词出现的次数
word_counts = collections.Counter(words)

# 使用heapq模块的nlargest函数找到出现次数最高的前5个单词及次数
top_5 = heapq.nlargest(5, word_counts.items(), key=lambda x: x[1])

# 输出结果
print("出现次数最多的5个单词及次数：")
for word, count in top_5:
    print("{0}: {1}".format(word, count))

输出结果：

出现次数最多的5个单词及次数：
the: 3
Twinkle: 2
twinkle: 2
little: 2
you: 2
