这是一个简单的文本处理任务,可以使用编程语言如Python来完成。首先,你需要读取输入的英文句子,然后分割成单词列表,排除掉标点符号。最后,按照出现顺序输出单词的数量以及每个单词。
下面是一个Python示例:
```python
import string
def count_words(sentence):
# 移除标点符号并将句子转换为小写
sentence = sentence.translate(str.maketrans('', '', string.punctuation)).lower()
# 分割单词并计数
words = sentence.split()
word_count = {word: words.count(word) for word in words}
# 按照出现顺序输出单词及次数
for word, count in sorted(word_count.items()):
print(f"{word}: {count}")
# 示例输入
sentence = "Hello, world! This is a sample sentence."
count_words(sentence)
```
运行这段代码后,它会输出每个单词及其在句子中的出现次数。如果需要只输出单词个数,可以直接返回`len(words)`。

好的,这是一个简单的Python程序,可以实现您的要求:
```python
sentence = input("请输入一个英文句子:")
words = sentence.split()
for word in words:
if word[-1] in [".", ",", "!", "?", ";", ":"]:
print(word[:-1])
print(word[-1])
else:
print(word)
```
您可以将英文句子输入到程序中,程序将把句子分割成单词,并按照要求输出每个单词。如果单词的最后一个字符是标点符号,则将标点符号和单词分别输出。
